Intel core i5 750 performance according to aida. Intel Core i5 with Lynnfield core. Top architecture - to the masses! Sufficient QPI bus bandwidth
The year 2009 was marked by the release of the updated Lynnfield processor architecture, the most accessible representative of which was the Cor i5-750 chip at that time. The characteristics of this semiconductor product are not that much different from today's quad-core CPUs from this manufacturer. Therefore, this processor is still relevant and allows you to solve most of the various tasks at the moment.
The niche of the processor market, which the hero of this review was focused on
With the release of the LGA1156 platform, Intel has divided the microprocessor market into the following segments:
Entry-level PCs were based on Celeron processors (these chips provided the minimum level of performance sufficient for office computers) and Pentium (in this case, one could even count on launching some new toys with minimal settings, but such a gaming system unit could only be called a game one ). The difference between these two products was the increase in the cache size and the increase in the processor clock frequency, and this made it possible to get additional performance percentages in practice.
The mid-range segment was occupied by chips of the i3 and i5 families. It was to this group of CPUs that the processor solution considered in this material belonged. The younger i3 models included only 2 physical blocks of program code processing. But due to the introduction of proprietary HT technology, this semiconductor crystal at the software level could already process information in 4 streams. But the i5s were full-fledged processors with 4 physical cores. They also have increased cache memory and support for TurboBoost technology. The latter made it possible to adjust the CPU frequency depending on the degree of optimization of the program code for multithreading, the thermal state of the semiconductor crystal and the level of complexity of the problem being solved.
Most productive system blocks both then and now are based on the i7 family of chips. They have 4 physical blocks of code processing, but support for HT technology allows you to get 8 threads at the software level. Also, the frequency formula in this case is increased, like the cache memory.
Although formally the hero of this review belongs to the middle class processor products, nevertheless, among almost all the software that existed at that time, it was he who could easily compete with the flagship microprocessor. Most of the software, even now, is focused on using 4 physical cores, and it is for this reason that there is currently no big difference in terms of performance between the older CPUs of this manufacturer.
Contents of delivery
This product was sold in two configurations. The more modest one was called TRAY. In this case, in addition to the CPU itself, an instruction manual, a warranty card and a sticker with the name of the chip model for the front panel were purchased. Such a package is aimed primarily at large assemblers of system units, but it is also sometimes purchased by computer enthusiasts. The second configuration option for this processor product was called BOX. In common people, the name "boxed version" was stuck behind it. In this case, the delivery list was supplemented with a cooler and thermal paste.
CPU socket
The Kor i5-750 was designed for installation. The characteristics of this processor socket indicated that it was oriented towards the assembly of single-chip system units. This socket made it possible in 2009 to organize computer systems that were completely different in purpose and cost. This computer platform remained relevant until 2011, when it was replaced by LGA1155. But even now, the products of this series continue to be relevant for at least one reason that the level of their performance still allows you to solve most problems.
Semiconductor crystal production technology
At the beginning of 2009, Cor i5-750 was produced according to a typical technology. The characteristics of this entire generation of chips indicate that they were all manufactured using the 45 nm process technology. At that time it was perfectly worked out and in this case there were no significant problems with the yield of suitable silicon wafers. In the future, it was replaced by technology with a tolerance of 32 nm.
Kesh
Like all modern most progressive processor products, the Intel i5-750 has a three-level cache. The characteristics of this semiconductor product in this case are as follows:
The first level included 4 64 KB segments tied to a specific computing module.
Similarly organized 4 blocks of 256 KB at the second level.
The cache at the third level was shared by all CPU resources and had a total size of 8 MB.
RAM
Subsystem has been significantly redesigned random access memory in solutions based on LGA1156, including the Core i5-750. The characteristics of this product indicated that, along with the controller, the RAM was moved from the motherboard to the semiconductor chip of the central processor. This made it possible to significantly increase the speed of the RAM. But, on the other hand, the integration of the RAM controller led to the fact that the chip could function only with a certain list of RAM sticks. In this case, this set was limited to DDR3-1066. Also, in combination with this CPU, it was possible to use faster memory cards, but the frequency of their operation was limited to only one value - 1066 MHz. In this case, it was impossible to get anything more.
Temperature Range. Thermal package
The processor i5-750 was designed for a thermal package of 95 W. The characteristics of this model of the central processor indicate the maximum allowable temperature value of 72 degrees. In the usual mode, the temperature regime of this chip was limited to values of 40-50 degrees. In the case of overclocking, this range increased and was already in the range of 50-60 degrees. In practice, it is not possible to load this CPU within the nominal operating range so that it reaches the maximum possible value. It was possible to go beyond the established boundaries only in two cases. One of them is a breakdown of the cooling system, and the second is overclocking the chip in combination with a complete cooler and running several resource-intensive applications on the PC.
Frequencies
2.7 GHz was set to the initial frequency for this CPU performance indicating support for TurboBoost technology. That is, this processor could adjust the frequency value and the number of active computation units. When using all four units, the maximum frequency was limited to 2.8 GHz. If the processor operated in dual-threaded mode, then the frequency value was 2.93 GHz. Well, in the case when only one unit for performing calculations was working, this value could generally increase to 3.2 GHz. There was also the possibility of overclocking this CPU. As experience shows, with the proper configuration of the system unit, this processor could be overclocked to 4 GHz and due to this, almost a 30% increase in performance could be obtained.
CPU architecture
As noted earlier, the 4 physical code processing modules included an Intel Core i5-750. The characteristics of this product indicated that it lacked support for HyperTrading technology. Therefore, at the software level, it was represented by the same 4 threads. And this value, even today, continues to be relevant due to the fact that most of the software is optimized for a maximum of 2 or 4 streams. In this case, the difference with the more expensive i7-family CPUs was hardly noticeable.
Owners' opinion. Price
This modification of the Core i5 was estimated at $ 213. The CPU 750 (its characteristics were really excellent as for 2009) made it possible to solve any problems. Even now, this CPU can handle almost all workloads with ease. Only the freshest toys can cause problems. But in this case, you can lower the quality of the displayed image, which will allow you to fully immerse yourself in excellent gameplay.
Outcomes
A decent processor product for 2009 was the Cor i5-750. Its characteristics continue to be relevant to this day and still allow most problems to be solved. Also, the advantages of this CPU model are affordable cost, four physical code processing units and excellent energy efficiency, as for the 2009 chip. But still, the owners of such system units will very soon have to think about the planned upgrade of their computing system.

In 2009, the American microprocessor manufacturer Intel presented a new line of crystals based on the modern Lynnfield architecture. The cheapest processor in this line is the Core i5 750, specifications which were almost identical to last year's line. Nevertheless, these crystals are very popular among users and can solve many modern problems.
Market positioning and price range
Engineers from the innovative technology development section, when developing a processor socket, LGA 1156 divided the die market into several categories:
- Processors of the Celeron and Penrium series. The former were designed to assemble budget system units ideal for performing office tasks, while the latter had more high level performance sufficient to run some modern PC games with low graphical interface settings. The main difference between both representatives was in the amount of cache memory and clock frequency, thanks to which a higher performance is achieved;
- CPUs of the Core i3 and i5 families, to which the model of the crystal considered in our today's article belongs. These processors are designed for advanced users in need of increased performance. Low-end models have only two physical cores, however, thanks to the hyper-threading technology capable of processing program code in four threads, these solutions are in no way inferior to similar AMD processors with 4 cores. CPU models of the Core i5 line are more powerful due to full four cores, increased cache, as well as proprietary TurboBoost technology, which provides tremendous performance gains when performing more complex tasks.
- Crystals Core i7 are the ideal solution for enthusiasts and professionals who, due to the specifics of their work, need powerful productive desktop computers. These processor models have four physical cores and HyperThreading technology, thanks to which the crystal is capable of operating in eight-threaded mode. In addition, this line of microprocessors has increased cache memory and increased clock speed.
Despite the fact that the CPU Core i5 750 is a representative of the mid-price range, in terms of its hardware characteristics and level of performance, it may well compete with some of its older brothers. The thing is that most modern programs and computer games are designed to work with quad-core processors, so there is no tangible difference in the process of performing various tasks between our today's hero and the flagship crystal lines.
Factory complete set
There are two options for the delivery of this processor to consumers: Tray and Box. The first option is cheaper and, in addition to the microprocessor itself, the consumer receives a FGT, an Intel branded sticker that can be glued to the system unit, and an instruction manual. The Trey package is designed primarily for more advanced users who assemble a powerful system unit on their own and want to install a more efficient cooling system for their CPU. The boxed version, which among ordinary people is called boxed, in addition to all of the above, contains Intel's proprietary cooling fan and thermal paste to provide better thermal conductivity between the crystal and the cooling heatsink.
The CPU Core i5 750 is designed to work with all motherboards based on the LGA1156 socket. The peculiarity of this connector is that it assumes operation on a single chip. At the time the processor went on sale, Socket LGA1156 allowed assembling completely different system units: from budget and simple machines to powerful gaming computers. This processor socket was popular until 2011, after which it was gradually superseded by the more modern LGA1155. Nevertheless, many users today continue to use processors and motherboards with socket 1156 due to the fact that their performance is sufficient to this day to solve a large number of tasks.
Technological process
Considering the fact that the CPU Core i5 750 hit store shelves in 2009, it is clear that it was manufactured using a 45nm process, which was one of the most modern at the time. This technology made it possible to create reliable and efficient processors with no problems. Later, engineers at Intel developed a thirty-two nanometer manufacturing process that made it possible to create thinner crystal plates.
Architecture
As mentioned at the beginning of this article, the Core i5 750 CPU is based on four physical cores. At the same time, this model does not support HyperThreading technology, as a result of which the processor operates in four-threaded mode. Nevertheless, this did not prevent the crystal from coping with the most difficult tasks and working with all modern software. Therefore, if you compare it with representatives of the older generation of Core i7 crystals, the difference in the speed of task execution will not be noticeable.
Cache memory
Like any other modern processor, the Core i5 750 has a three-level cache memory, which has the following hardware characteristics:
- The cache memory of the first level consists of four clusters, each of which is equal to 64 KB, working with one computational module;
- The cache memory of the second level is arranged in the same way, however, the size of each block is 256 kilobytes;
- The cache of the third level is used by all computational modules of the processor, and the size of each cluster is 2 megabytes.
RAM compatibility
One of key features processor socket 1156 is that engineers have completely redesigned the compatibility with RAM modules. Among the main changes is the transfer of the north bridge, which is responsible for supplying power to the crystal, and the RAM controller to the CPU, thanks to which the engineers managed to significantly increase the speed of the RAM memory. As for compatibility with RAM modules, the Core i5 750 supports the work with third-generation DDR memory sticks and a bandwidth of 1066 MB. It should be noted that installing a more expensive RAM memory that supports a higher frequency does not give any increase in the speed of information exchange between the RAM and the microprocessor.
Thermal package and operating temperature
The thermal package of the microprocessor considered in our today's article is 95 watts. Thus, the maximum crystal temperature when performing complex operations does not exceed 72 degrees. The temperature in normal operation is around 45 degrees, and after overclocking it rises to 55 degrees. However, this is all about the official information provided by the manufacturer, but how does this crystal behave in practice? Under maximum load, it is possible to bring the processor to the maximum temperature only if the cooling cooler fails, or when an overclocked CPU is running with resource-intensive applications on a weak cooling system.
Clock frequency
The maximum frequency of the Core i5 750 is 2.7 GHz, which is not used when performing everyday tasks. The crystal supports the innovative TurboBoost technology, which automatically adjusts the clock speed of each core at the software level depending on the complexity of the operations being performed. With the simultaneous operation of four cores in four-threaded mode, the peak value of the clock frequency is 2.8 GHz, and when performing tasks in 2 threads, this figure increased to 2.93 GHz. But when only one computing unit was operating, the operating frequency could increase to 3.2 gigahertz. In addition, the manufacturer supplies the crystal to stores with an unlocked multiplier, so anyone can overclock the CPU and get a thirty percent increase in performance.
Retail value and consumer reviews
The purchase of a CPU Core i5 750 will cost users approximately $ 213, which is quite acceptable, since in 2009 it was possible to assemble a powerful gaming machine on the basis of this crystal. Moreover, even today this CPU has not lost its relevance and perfectly copes with any tasks. Some problems may arise when launching the latest computer games with maximum settings for graphic effects, but at minimum settings this kid provides a very comfortable gameplay.
Conclusion
The CPU Core i5 750 from Intel Corporation became a real masterpiece of high technology in 2009, the demand for which remains to this day. This crystal will be an excellent solution for the majority of average users who do not distinguish between work and leisure, and use their computer both for office tasks and to enjoy their favorite toys. The main advantages of this model are low cost, excellent performance and low power consumption.
A little over a year has passed since the launch of the Nehalem platform, but the prices for the new processors still cannot be called affordable. The expansion of the modern line of CPUs at the expense of models based on the Lynnfield core for LGA1156 did not in any way affect the pricing of the older brothers, and they themselves did not differ in democratic cost. Until recently, the most economical processor based on the new architecture was the Core i5-750, which led to a fairly large popularity of this model. And even the recent appearance of Clarkdale processors from the same series is unlikely to shake the position of the "old man", which has real four cores versus four "virtual" ones in new products. But we will have a separate material devoted to Clarkdale, and in this article, as you might have guessed, we will focus specifically on the Core i5 750.
In retail, the Intel Core i5 750 comes in a boxed version, but sometimes you can find tray-options, which are provided with a 12-month warranty from the seller.
The standard cooler has a rather compact size and a small heatsink height; the core is made of copper. The design does not differ from the cooling systems of processors with the LGA775 construct.
The architecture of Lynnfield processors was discussed in detail by us in one of the previous materials. The Northbridge is fully embedded in the processor, which itself provides support for 16 PCI Express 2.0 lanes. By the way, this also gives rise to a small drawback of the platform, connected with the limited bandwidth of the interfaces of two video cards operating in CrossFireX mode. Unlike their predecessors for Socket LGA1366, the new CPUs have only a dual-channel DDR3 memory controller. Thanks to the x6 multiplier (effective x12), the new Core i7 processors in nominal modes can work with DDR3-1600 (not an officially supported standard), and the younger Lynnfield, Core i5 750, in particular, with a x5 (effective x10) multiplier with DDR3-1333. Higher memory frequencies can only be used by raising the base frequency (BCLK), and if you are using high frequency memory, then for its X.M.P. the board will automatically raise BCLK and decrease the multiplier on the processor as the voltages are adjusted accordingly. For DDR3-2000, the reference frequency will be set to 200 MHz, and the multiplier on the Core i7 750 processor will be x14 instead of x20. If the memory does not have X.M.P. for LGA1156 processors, then the user will need to make all adjustments in manual mode... The frequency of the Uncore block, which includes a memory controller and a shared L3 cache, is fixed relative to the base frequency by means of a x16 multiplier at 2130 MHz. The QPI bus now connects the processor only with the PCI Express controller, its frequency is formed as the product of BCLK by x18 (x36), which gives 2400 MHz (4800 GT / s). A lower multiplier of x16 (x32) can also be set manually.
The processor frequency in the nominal mode is 2.66 GHz with a multiplier of x20. The quad-core Core i5 750 lacks Hyper-Threading support.
Turbo Boost can increase the frequency of individual cores when running applications that are poorly optimized for multithreading. This overclocking can be up to 4 points (133 MHz) for one of the cores. More specifically, in single-threaded applications, the loaded core will operate at 3.2 GHz. If the load falls on two cores, then their frequency rises to intermediate values, and even with a load on all cores, the frequency of all of them will rise by one point. In the latter case, we actually get a quad-core CPU clocked at 2.8 GHz (at x21 multiplier) instead of 2.66 GHz. By the way, such a multiplier can be initially set manually for the Core i5 750 in the BIOS of almost all LGA1156 motherboards and without activating the Turbo Boost mode.
For tests in nominal mode, we used a 4 GB memory kit (Team TXD34096M2000HC9DC-L), which worked with timings of 7-7-7-20. All other delays and settings are shown below in the screenshot of the CPU-Tweaker utility.
Well, a few words about overclocking. It is carried out by increasing the base frequency. Since the frequencies of other blocks and DDR3 memory depend on it, the corresponding multipliers are lowered on them if necessary. So for DDR3, you can set the minimum multiplier x6, which in nominal will give a frequency of 800 MHz, and when BCLK is overclocked to 200 MHz, already 1200 MHz. Reducing the QPI frequency in Lynnfield processors is of no practical use for overclocking (at least with air cooling). But to reduce the Uncore frequency in overclocking will not work at all, and at 200 MHz according to BCLK this unit will work already at 3200 MHz. However, increasing the L3 cache frequency will only have a positive effect on performance.
With air cooling, all Core i5 processors obey the BCLK frequency of about 200-220 MHz. Having in stock several budget motherboards for Socket LGA1156, we found out that the base frequency limit of our CPU (with air cooling) is 220 MHz. At higher values, significant system instability was observed. Thus, with the maximum multiplier x21 "in the air", theoretically, you can even get 4620 MHz. In fact, we stopped at 4066 MHz, at which full stability in stress tests was maintained (OCCT, LinX, etc.). Note that given result achieved on a Gigabyte GA-P55M-UD2 board with a CPU Vcore of 1.4 V and a QPI / Vtt Voltage of about 1.35 V. Further overclocking required a significant increase in voltages for stability, which entailed overheating in stress tests.
All memory settings during overclocking are shown in the following screenshot:
As you can see above, the overclocked memory frequency was only 642 MHz (effective 1284 MHz). In fact, the Team memory kit itself is designed for 2000 MHz, but with Gigabyte board GA-P55M-UD2, when overclocking the processor, it was simply impossible to set the memory to a more efficient mode. At a higher multiplier, the system freezes before loading the operating system, and raising the corresponding voltages did not help. And in the nominal mode, the board had problems with the X.M.P. profile, but we will cover these nuances in a separate article on this board. Due to the "incompatibility" of the high CPU frequency and high memory multipliers (by the way, we met with something similar in some AMD Phenom II units), we had to limit ourselves to a low DDR3 frequency, but at 6-6-6-16 delays, which should somehow compensate for the lag even from the nominal 1333 MHz. For a slight increase in the memory frequency with its minimum multiplier, the multiplier on the CPU was also specially lowered so that it was possible to raise the BCLK frequency even higher.

Testing methodology
The testing methodology is described in the previous material. POV-Ray was excluded from the list of tests, because the built-in performance test in the version 3.7 beta 27 we are using did not work correctly on the LGA1156 platform, and in newer versions the results have changed significantly on older processors. In the absence of an opportunity to repeat the test in the new version of POV-Ray on processors from our list, we had to do without this program. For general information, we can only note that in POV-Ray 3.7 beta 35, the Intel Core i5 750 processor showed a result almost 10% lower than the Core 2 Quad Q9550, and with Turbo Boost enabled, it was 5% lower. Resident Evil 5 was excluded from gaming tests due to the strange behavior of the "fixed test" and "limiting" performance on quad-core CPUs after running the application on dual-core configurations.
Test results
Synthetics. Application software
PCMark Vantage
The first synthetic test demonstrates the unconditional superiority of the Core i5-750 over the rest of the test participants, even surpassing the Phenom II X4 955 operating at 3.2 GHz. Compared to the Yorkfield-based Core 2 Quad, Lynnfield has an advantage of about 13% at a single frequency.
In this test, the difference is no longer so great, although again Lynnfield's lead over the older Yorkfield tends to 10%. Unlike the previous overclocking test, the Core 2 Quad Q9505 and Core i5-750 demonstrate identical results.
In the Productivity Suite benchmark, we again see the advantage of Lynnfield over Yorkfield with 12MB of cache by about 10%. If senior AMD processor in this test it bypasses rivals Intel of the previous generation, the Core i5 is already too tough for it.
In this archiver, Lynnfield has a huge advantage over its predecessors - more than 30%. Activating Turbo Boost helps you win another couple of percent, but no more. The leading position of Core i5 with overclocking only strengthens, and at 4066 MHz this processor already demonstrates a 40% advantage over the Q9550 and 47% over the Phenom II X4 955. However, the performance test results in WinRar strongly depend on the performance of the memory subsystem. archiving, the difference may not be so staggering.
The 7-Zip archiver is pretty cool about the Lynnfield processor. The performance of the Core i5 is only slightly higher than that of the Core 2 Quad Q9450. It manages to bypass the Q9550 by activating Turbo Boost. In the same mode, the considered processor falls short of only 0.6% of the performance of the Phenom II X4 940 operating at 3 GHz. With overclocking, the Core i5-750 is again ahead of the pack.
Paint.Net
In this test, Lynnfield at 2.66 GHz was only 1% faster than Yorkfield with 12 MB of cache at the same frequency. In Turbo Boost mode, our processor is already on par with the Core 2 Quad Q9550. With overclocking, it is quite traditional that the Core i5 outperforms other rivals, the difference with the Core 2 Quad is again not great, but already more than 3%.
In Adobe Photoshop, the junior Lynnfield confidently outperforms all other Intel rivals even without Turbo Boost, yielding only 11 seconds to the AMD Phenom II X4 955. In turbo mode, the Core i5 is out of competition, outperforming the senior Phenom II processor by more than a minute. With overclocking, the Core i5-750 copes with the task almost two minutes faster than the older Core 2 Quad, operating at frequencies of about 4 GHz, and almost three minutes faster than AMD rivals overclocked to 3.7-3.8 GHz.
CineBench
At the same frequency, the difference between Lynnfield and Yorkfield with 12 MB of cache reaches 13% in favor of the former. In Turbo Boost mode, the Core i5 processor outperforms its steel competitors. Without "turbocharging" the CPU is second only to the Phenom II X4 955, and even then by less than one percent. And at a frequency of 4066 MHz, the processor in question is completely out of competition: the Core 2 Quad at 4 GHz is inferior to it by up to 19%, and the Phenom II X4 at frequencies of 3.7-3.8 GHz is up to 33%.
Xvid video encoding in VirtualDub
Again, no surprises. The Core i5 is the fastest to do the job. Only without Turbo Boost, only the Phenom II X4 955 demonstrates an identical level of performance (and this is with a 540 MHz frequency). With the same frequency, Lynnfield beats Yorkfield for almost a minute. When overclocked to 4.07 GHz, the advantage of the Core i5-750 over other rivals at higher frequencies is calculated in even greater numbers. Interestingly, the younger Core 2 Quad Q8300, even at 3.5 GHz, is slightly inferior in performance to the Core i5-750 with Turbo Boost. And the older Phenom II X4 only with overclocked to 3.8 GHz outperforms the processor in question in this mode for only seven seconds.
X264 Benchmark
In nominal modes, the Core i5-750 is inferior to the Phenom II X4 955 alone, and even then, not so much. The advantage of Lynnfield over Yorkfield at one frequency reaches 12%. With overclocking, not a single processor is simply able to adequately compete with the CPU in question, which bypasses its predecessors by almost 16%, and AMD representatives by 20% or more.
PHP Benchmark
In this test, which is mainly sensitive only to the frequency of the processor itself, the Core i5-750 also did not hit its face in the dirt, and in Turbo Boost mode it turned out to be no worse than the high-frequency Phenom II X4 955. With overclocking, the processor again copes with the task faster than anyone else. although the difference with the Core 2 Quad is already minimal.
Fritz Chess Benchmark
The Core i5 is slightly faster than the Core 2 Quad Q9550 only in Turbo Boost mode. At 2.66 GHz, it is slightly inferior to the older quad-core CPUs of the previous generation, bypassing the Core 2 Quad Q9450 by only 2.8%. With overclocking, the younger Lynnfield strengthens its position, beating its closest competitors (Core 2 Quad Q9505 and Q9550) by about 7%.
Super pi
In this test application, the Core i5-750 demonstrates a very impressive advantage over all processors in nominal mode, even without Turbo Boost enabled. Lynnfield has a 23% advantage over Core 2 Quad on a Yorkfield core with 12 MB of cache at the same frequency. The rest of the overclocked rivals at best show the same result as the Core i5 without overclocking, but with Turbo Boost. Game applications
The first gaming test demonstrates the complete superiority of the Core i5-750 over the rest of its rivals. Younger Lynnfield manages to bypass Core 2 Quad Q9550 and Phenom II X4 955 even without Turbo Boost activation. And when this mode is enabled, the Core i5 demonstrates the same results as the overclocked AMD Phenom II X4. Intel's predecessors for Socket LGA775 are not so sad, but they cannot compete with the overclocked Lynnfield either, despite the fact that they all reached frequencies close to 4 GHz with overclocking.
Battlestations: Pacific
In this game, despite high fps, we "rested" on the capabilities of the video card, and, as a result, the difference in the results is minimal. This is also explained by the peculiarity of the selected script scene, which creates a minimum load on the CPU. In any case, the Core i5 along with the Core 2 Quad Q9550 demonstrate the highest scores in this game. When Turbo Boost is activated, a minimal drop in performance is noticeable, but it is difficult to talk about anything specific with such a small difference.
X3 Terran Conflict
In this game, the Core i5-750 doesn't even need Turbo Boost to beat the competition. When activated, the result of the CPU in question turns out to be 5-10% higher than that of the older Core 2 Quad and 9-17% higher than that of the Phenom II X4 955. With overclocking, the lag of AMD processors reaches a huge 25-28%, and Q9550 with its 3.96 GHz lags behind the leader with a frequency of 4.07 GHz by 8-10%. Younger Core 2 Quad and Phenom II X4 with overclocking only reach the performance of an unclocked Core i5 with Turbo Boost.
H.A.W.X.
One of the few gaming applications in which AMD processors are significantly more productive than the old Intel Core 2 Quad, and even then, only in low resolution. But the newer Core i5-750, unlike its predecessors, is not inferior to competitors from the "green camp", bypassing their older processor with a frequency of 3.2 GHz at 2.66 GHz by as much as 15%. The superiority of Lynnfield over older Yorkfield at one frequency reaches almost 35%! But the Turbo Boost mode has almost no effect on the result - only plus 3%. During overclocking, the gap between the leader and other rivals is no less impressive.
But with the maximum image quality, the alignment of forces changes. So nimble in a weaker mode, the Core i5-750 suddenly takes the last place. Interestingly, the Turbo Boost mode does not affect performance in any way, and there is little sense from overclocking.
World in Conflict
Intel Core i5 once again demonstrates a level of performance unattainable for competitors. The advantage over Yorkfield is about 30%. All processors except Core 2 Quad Q9550 with overclocking only approach the leader's performance in nominal. And the Core 2 Quad Q9550 at 3.96 GHz does not have a particularly impressive advantage over the Core i5-750 with Turbo Boost, given the huge difference in frequency.
Higher resolution and heavier graphics settings slightly temper the fervor of the "unstoppable" Core i5-750, and now all overclocked Core 2 Quad manage to bypass its result in nominal mode. By minimum fps the leader is losing ground to the older Core 2 Quad even more noticeably, and even in the nominal value does not bypass the Core 2 Quad Q9550 in this parameter.
Unreal Tournament 3
In Unreal Tournament 3, the irreplaceable leader pushes all rivals to the margins. For AMD processors, everything is completely sad - even when overclocked to 3.8 GHz, they cannot demonstrate the same results as the Core i5-750 at 2.66 GHz. And the advantage over its predecessor Core 2 Quad Q9450 reaches almost 30%, and Core 2 Quad Q9550 is inferior to a significant 20%. Turbo Boost boosts Lynnfield's performance by up to 4%. With overclocking, the balance of forces between Intel processors almost does not change, but AMD's lag behind them only increases.
S.T.A.L.K.E.R .: Clear Sky
Unlike the previous game in this domestic project, the Core i5-750 secures its leadership without any reservations. Its advantage over the older models Core 2 Quad and Phenom II X4 reaches almost 30% in low resolution and 23% in high resolution. And even with overclocking, competitors hardly manage to somehow make up for such a lag. AMD processors, by tradition, when overclocked to 3.7-3.8 GHz, do not reach the Core i5 at the nominal 2.66 GHz.
Far cry 2
In a low resolution, the Core i5-750, as usual, turns out to be "faster" than everyone else, and the "poor" AMD processors again cannot achieve the same results when the frequencies are increased to 3.7-3.8 GHz.
But at maximum settings, quite unexpectedly, the Core i5 again becomes an outsider, as it was in H.A.W.X. And again, Turbo Boost does not give any advantages, as well as overclocking (mainly an increase in the minimum fps).
In low resolution, everything is quite predictable and the leadership position of the Core i5-750 is undeniable. The advantage of Lynnfield over Yorkfield with 12 MB of cache at the same clock speed of 2.66 GHz is 26%. With Turbo Boost activated (which brings only 3%), the advantage over the older Core 2 Quad Q9550 and Phenom II X4 955 reaches 21-22%, and when overclocked these rivals reduce their lag to only 17-20%.
In high resolution in nominal modes, the leadership of the Core i5 also raises no questions, even though in this mode the performance is already significantly limited by our video adapter. But with overclocking, the CPU for some reason demonstrates the result slightly lower than the older Core 2 Quad. The difference is, of course, scanty, but still this is not an error, which, according to the results of several test runs, usually fits into much smaller frames.
Crysis warhead
Crysis Warhead does not bring any surprises, and at all resolutions Core i5 is the undisputed leader, and the identical results with the Q9550 at 1280x1024 during overclocking are fully explained by the insufficient power of the video card, which played the role of a "limiter". In low resolution, the advantage of Lynnfield over Yorkfield at a single frequency of 2.66 GHz reaches 17.5%. Turbo Boost activation helps to increase the result by 4.5%, and AMD rivals cannot achieve such indicators even in overclocking. The second place on the "pedestal" Core 2 Quad Q9550 is inferior to the leader from 10% (without Turbo Boost) to 16% in nominal and 10% during overclocking.
Grand Theft auto 4
According to the test results in this extremely processor-dependent game, it can be seen that the requirements for the video subsystem are also quite high, despite the far from advanced graphics. As a result, in both low and high resolutions we hit a certain "ceiling" and the differences between the processors are calculated in very scanty values, which in case of instability of the built-in benchmark itself can often be attributed to measurement errors. True, this does not interfere with the resolution of 1024x768 at medium settings, the Core i5-750 quite confidently takes the place of the leader, but at higher settings it is already slightly inferior to the Phenom II X4 955. But in the same mode (at a resolution of 1280x1024) with overclocking, when the results of all processors, it would seem, ran into the boundary value of 56 frames and higher, the video card is no longer "letting in", the Core i5 suddenly showed a higher (by almost 1 frame) result. And this is clearly beyond the margin of error, and once again demonstrates the powerful potential of Lynnfield.
Armed assault 2
We have already noted the low results of AMD processors in this test application in a recent article. As a reminder, we are using a pre-release demo version of the game, which is equipped with its own gaming test. It is possible that in full version For a game that is overgrown with a huge number of patches, the performance of the Phenom II has improved significantly.
The object of our review, Intel Core i5-750, is quite expectedly the leader, but the Core 2 Quad Q9550 is literally a few percent behind it. With overclocking, the Core i5 at 4.07 GHz bypasses the Core 2 Quad Q9550 at 3.96 GHz by a more significant 10%.
Cryostasis: Sleep of Reason (Anabiosis)
In this poorly optimized application for multi-core processors, the Core i5-750 can bypass the older Core 2 Quad Q9505 and Core 2 Quad Q9550 only when Turbo Boost is activated. With overclocking, Lynnfield's most significant advantage is in the minimum fps (which is more relevant for this benchmark with NVIDIA PhysX software processing), and in terms of average fps, the overclocked older Core 2 Quad is on par with it.
conclusions
It's time to summarize some of the results of our testing. The Intel Core i5-750 we reviewed turned out to be out of competition against the background of other processors of the previous generation and against the background AMD solutions... In almost all applications, it has demonstrated a performance level higher than running at a higher Core frequency 2 Quad Q9550, sometimes even without Turbo Boost activation. The very benefit of this auto-overclocking technology for different cores brings on average an increase of no more than 5%, although in rare single-threaded tasks (for example, in the SuperPi test) it can reach all 15%.
The junior Lynnfield has the most significant advantage in gaming tests, but it must be admitted that in a number of applications the situation is ambiguous. With a significant advantage over all other CPUs at low settings, the Core i5-750 could be slightly inferior to them with high-quality graphics at a higher resolution. This was most clearly manifested in FarCry 2, when at a resolution of 1024x768 Lynnfield's gap from its closest competitors was almost 17-20%. But at the same time, at 1280x1024 and rendering in DirectX 10, these same competitors demonstrate the result 15% higher. In similar applications, overclocking the CPU itself brings minimal benefit, and activating Turbo Boost has almost no effect on the result. The mechanism of such a decrease in performance is not entirely clear, we can only state that the Core i5-750 is not always good at high resolutions and at high graphics settings. But this does not diminish the merits. this processor... Maybe it is somewhere inferior to competitors in certain conditions, but in most games it demonstrates performance that is unattainable for them, often at the same frequency, the superiority over its predecessors on the Yorkfield core (with a maximum of 12 MB L2 cache for them) reaches 30 % and more! It is also significant that the younger Yorkfield with 4 MB of cache in a number of applications reaches a comparable level of performance only with overclocking to 3.5 GHz. But the Core i5-750 is also the youngest representative of its family. Progress, as they say, is evident.
However, the older Core 2 Quad against the background of the Core i5-750 in low resolutions are also not impressive, but thanks to overclocking to 4 GHz they are even more or less comparable to a newcomer in some gaming applications. As for the overclocking of the object of our article, its frequency potential has grown a little relative to its predecessors. The 4.07 GHz we received does not seem to differ much from the 4 GHz in the Core 2 Quad Q 9505 or 3.96 GHz in the Core 2 Quad Q 9550, but further Lynnfield overclocking was limited mainly due to the insufficient performance of the Thermalright Ultra-120 eXtreme cooler ... If we take into account that we used a powerful fan at maximum speed, then when working in quiet modes with air cooling systems in everyday use, the frequency limit for all these processors will be approximately the same. But users of CBO can well count on the great results of overclocking the Core i5-750.
Due to Intel's pricing policy aimed at promoting new products, there is no sense in buying an older Core 2 Quad Q9550 now, because a Core i5-750 on the local market will cost you at least $ 65 cheaper with higher performance. And Core 2 Quad Q9500 or Core 2 Quad Q9505 are also not particularly attractive in terms of price. This situation makes many Core 2 Duo users, instead of upgrading to Core 2 Quad, think about a complete platform change. And the Core i5-750 in this case will be the ideal choice, because at its performance level it is best processor for $ 200-220.
AMD processors against the background of the Core i5-750 generally look depressing, especially in gaming applications. In particular, the Phenom II X4 955, with a frequency difference of about 500 MHz in games, is almost always inferior to the younger Lynnfield. At the moment, it is simply impossible to consider AM3 processors as a basis for a promising gaming platform, and this is sad. It can be countered that the cost of AMD products is lower and for the price of Intel's solution, you can take the top-end Phenom II X4 965 with a frequency of 3.4 GHz. But will these additional 200 MHz help, if 500 MHz did not really help the Phenom II X4 955? .. I would like to see more worthy and competitive solutions from AMD, which could withstand not only the previous generation Intel processors, but also newer models. Let's hope that the upcoming Phenom II X6 will meet our expectations.

The data is obtained from tests of users who have tested their systems both with and without overclocking. Thus, you see the average values corresponding to the processor.
Speed of numeric operations
Different tasks require different CPU strengths. A system with few fast cores is great for gaming, but will outperform a system with a lot of slow cores in a rendering scenario.
We believe that a processor with at least 4 cores / 4 threads is suitable for a budget gaming computer. At the same time, individual games can load it by 100% and slow down, and performing any tasks in the background will lead to a FPS drawdown.
Ideally, the buyer should aim for a minimum of 6/6 or 6/12, but keep in mind that systems with more than 16 threads are currently only applicable for professional tasks.
The data was obtained from tests of users who tested their systems both in overclocking (maximum value in the table) and without (minimum). The typical result is shown in the middle, the color bar indicates the position among all tested systems.
