Intel core 2 duo e6600 year of manufacture. Available options for embedded systems

Alexey Shobanov

“Finally, what we have been waiting for has happened!” For the third month now, they have been replete with exclamations like these or ones similar in meaning. computer publications, devoting more and more reviews and tests to Core 2 Duo processors, the release of which Intel announced in mid-July. The appearance of these chips, built on the new Intel Core microarchitecture, without exaggeration, became the main event of the current year, demonstrating to everyone that the “crisis of the genre” has been overcome and all the problems associated with the previous Intel NetBurst microarchitecture are behind us. Naturally, our magazine did not stand aside either - a number of articles were published on its pages, telling both about the features of the architecture of new processors, and about chipsets and motherboards designed to work with them. But, unfortunately, until recently we were not able to conduct a direct comparison of new processors from Intel with solutions from their main competitor - Advanced Micro Devices (AMD). Moreover, AMD, anticipating the release of Core 2 Duo, presented its new platform AM2 (which was also described in detail on the pages of our magazine). It is based on processors built on the AMD64 microarchitecture, which has long been familiar to us, but in this case has a built-in memory controller capable of supporting DDR2 SDRAM memory and made in a new form factor with an AM2 processor socket. Today we finally had the opportunity to bring our competitors face to face and evaluate their capabilities in performing a wide range of tasks. For comparison, we chose Intel Core 2 Duo E6600 and AMD Athlon 64 X2 5000+, and here's why: both models have about the same price. Thus, the AMD Athlon 64 X2 5000+ processor in batches of a thousand units costs $301, and the Intel E6600 costs $316. In addition, today both chips occupy the same place in model range manufacturing companies, being the second oldest model in their respective lines. In table 1 shows some of the key characteristics of these chips.

In order to compare the capabilities of these two processors, we used a number of specialized programs, as well as test scenes and scripts for popular applications, which allowed us to evaluate the performance computer systems based on these central processing units to perform various tasks. Here is a list of tests and applications used:

• working with 3D graphics:

Alias ​​WaveFront Maya 6.5 (script SPECapc Maya 6.5 v1.0);

For testing, two stands were assembled:

• for AMD Athlon 64 X2 5000+ processor:

Motherboard - ASUS M2N32-SLI Deluxe (chipset - NVIDIA nForce 590 SLI),

Hard drive: Seagate Barracuda 7200.7 120 GB (ST3120827AS), file structure NTFS;

• for Intel Core 2 Duo E6600 processor:

Motherboard - ASUS P5B Deluxe (chipset - Intel P965 Express),

Video card - Sapphire RADEON 1900 XTX,

System memory - 2xCorsair CM2X512-8500 in DDR2-800 SDRAM mode (total capacity 1 GB), timings 4-4-4-12 (CAS Latency-RAS to CAS Delay-Row Precharge-Active to Precharge),

Hard drive - Seagate Barracuda 7200.7 120 GB (ST3120827AS), NTFS file structure.

Testing was carried out under operating system control Microsoft Windows XP SP2 with ATI CATALYST 6.7 video driver installed.

Let us turn to the results we obtained during testing (Table 2). Based on the results of synthetic tests FutureMark PCMark 2005 and CrystalMark 9.0, which allow us to evaluate the performance of individual subsystems of a computer system, we see that the performance of the processor subsystem and memory subsystem of the configuration, which is based on Intel processor Core 2 Duo E6600, 10-15% higher than similar subsystems based on AMD Athlon 64 X2 5000+. At the same time, subtests related to other subsystems (disk and graphics) did not reveal any significant advantage of the Intel platform, with the exception of the OpenGL test OGL CrystalMark 9.0, which, however, calculates geometry with intensive loading central processor, therefore, it is impossible to say that this is a pure test of the graphics subsystem. Moreover, in two other graphics tests of the same test suite - GDI and D2D - the AMD Athlon 64 X2 5000+ platform had a noticeable advantage over the competing solution. A similar situation arose in subtests assessing the performance of the disk subsystem: according to the results of the HDD FutureMark PCMark 2005 test for a computer system based on an AMD processor, it was the same for both computer systems, and according to the results of the HDD CrystalMark 9.0 test it was 12% higher than for the platform Intel. From all that has been said, we can draw a very important conclusion: when conducting all subsequent tests, the resulting difference in performance between the compared configurations (if we're talking about that the advantage is on the side of the Intel platform) is determined primarily by the capabilities of the processor subsystem and the processor-memory link, since neither the graphics nor the disk subsystem in this case has any advantage over a competing solution.

Next up is a set of tests for the Science Mark 2.0 utility, designed to evaluate system performance when performing scientific calculations. Looking at the results of these tests, it is easy to see that when performing scientific computing (Molecular Dynamics, Primordia and Cryptography subtests), the advantage of the AMD Athlon 64 X2 5000+ looks very convincing. This result is quite understandable, since it has long been known that floating point operations (on which all calculations performed in this case are based) are the strong point of AMD processors with the K8 generation core, as well as the K7. Although in this case it is very interesting that in a pure synthetic test for performing BLAS/FLOPs floating point operations (calculating special matrices ranging in size from 64x64 to 1536x1536), the Intel processor turns out to be a third faster!

Another set of tests where the AMD Athlon 64 X2 5000+ processor managed to prevail over the Intel processor was the VeriTest 2004 package, which simulates the user’s work with office applications (VeriTest Business Winstone 2004 v.1.0.1), as well as creating the Internet -content (VeriTest Multimedia Content Creation Winstone 2004 v.1.0.1). It can be assumed that in this case the slight advantage of the AMD platform is due to a slightly best job disk subsystem and higher processor clock speed (2.6 versus 2.4 GHz for the Intel Core 2 Duo E6600). Moreover, in the multitasking test when working with office applications (VeriTest Business Winstone 2004 v.1.0.1 Multitasking Test) Intel platform turns out to be more productive. Most likely, one of the reasons for this was the more efficient use of the second level cache (L2), which is common and not individual for each of the cores (as is implemented in processors of the AMD Athlon 64 X2 family) and also has four times more volume (4 MB versus a total of 1 MB for the AMD Athlon 64 X2 5000+).

On tasks of encoding video and audio files and archiving, the system with the Intel Core 2 Duo E6600 processor turned out to be significantly faster than the platform on the AMD Athlon 64 X2 5000+ - its gain here ranged from 4.4 (MainConcept H.264 Encoder v.2.0) to 24. 5% (MainConcept MPEG Encoder v.1.51). Moreover, this advantage was achieved by the processor from Intel has already not due to a higher clock frequency, as was the case with NetBurst architecture processors, but due to better organization working with streaming data...

What about games? Until recently, the advantages when testing gaming applications unconditionally remained with AMD processors. And it was on its own field that the brainchild of Advanced Micro Devices this time suffered a crushing defeat. In all gaming tests The first was the platform based on Intel Core 2 Duo E6600, and in test scenes of real games the advantage was quite significant (from 21% in the scene for Quake 4 to 38.8% for Half-Life 2).

In tests assessing system performance when working in the popular 3D packages Discreet 3ds Max 7.0 and Alias ​​WaveFront Maya 6.5, as well as when executing a script simulating the user's work processing digital photos in Adobe Photoshop CS2, the advantage of the Intel Core 2 Duo E6600 processor over its competitor also does not raise the slightest doubt.

Thus, based on the results of this comparison, we can state: the new Duo 2 Core processors from Intel, built on the Intel Core microarchitecture, today significantly surpass the solutions of competitors in terms of performance, the only serious of which is Advanced Micro Devices. In addition, we can say that the enemy, represented by the AMD Athlon 64 X2 5000+, which acted here as a successor to the glorious legacy of processors with the AMD64 microarchitecture, was beaten with its own weapons. Thus, having abandoned the race for frequencies, which was embodied in the processors of the family Intel Pentium 4 with their NetBurst microarchitecture, Intel has focused on increasing the number of operations performed per clock and optimizing the execution of calculations in Intel Core. It is also interesting that the Intel Core 2 Duo E6600 outperformed its opponent not only in pure performance, but also in all its relative terms: relative performance per unit of cost and relative performance per unit of power. Let us recall that the TDP of the Intel Core 2 Duo E6600 processor is 65 W, and the power dissipation level of the AMD Athlon 64 X2 5000+ is 89 W. Directly comparing these values, of course, is not entirely correct, since companies use different methods to determine them, however, they are quite suitable for making some rough comparison.

Not much time has passed since the release of the previous material about new Intel processors, so it would be more logical to perceive this article not as an independent one, but as a kind of addition. It just so happened that the Intel Core 2 Duo E6600 processor fell into our hands after the publication of the first article. Of course, in itself it is not very interesting because... differs from the Core 2 Duo E6700 only in the multiplication factor reduced by one (and, accordingly, at 266 MHz lower frequency). Of course, it would be much more interesting to test the E6300/6400 with a “halved” cache, or even the youngest in the E4200 line, which also had the bus reduced to 800 MHz. Unfortunately, these CPUs have not yet reached us. Therefore, in the absence of the most desirable things, we suggest that you read yet another material on the topic “performance of the new Intel architecture in widespread real-world tasks.” Fortunately, the topic couldn’t get too boring - this is only the second material devoted to it :).

Intel Core2 6600 test

The data comes from user tests who tested their systems both overclocked and unoverclocked. Thus, you see the average values ​​​​corresponding to the processor.

Numerical speed

Different tasks require different strengths CPU. A system with a small number of fast cores will be great for gaming, but will be inferior to a system with a large number of slow cores in a rendering scenario.

We believe that for the budget gaming computer A processor with at least 4 cores/4 threads is suitable. At the same time, some games can load it at 100% and slow down, and performing any tasks in the background will lead to a drop in FPS.

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 suitable for professional applications.

The data is obtained from tests of users who tested their systems both overclocked (the maximum value in the table) and without (the minimum). A typical result is shown in the middle, with the color bar indicating its position among all systems tested.

Accessories

We have compiled a list of components that users most often choose when assembling a computer based on Core2 6600. Also, with these components the best test results and stable operation are achieved.

Most popular config: motherboard for Intel Core2 6600 - Asus M4A785TD-M EVO, video card - GeForce 6600 GT.
