Intel 3.2E vs. 3.2EE vs. 3.2C: Comparing Baseline Performanceby Wesley Fink on February 12, 2004 2:46 PM EST

Performance Test: ConfigurationTo provide a baseline for future motherboard tests, we tested all three 3.2GHz processors using our latest Motherboard tests. The same Socket 478 motherboard, the widely available and excellent performing Asus P4C800-E, was used for all tests. This is our standard Socket 478 motherboard for memory testing, and it is the motherboard recommended by both Corsair and OCZ for running their fastest DDR550 memory.
|Performance Test Configuration - 3.2GHz Socket 478|
|Processor(s):||Intel Pentium 4 3.2E (Prescott, 1MB L2 cache)
Intel Pentium 4 3.2EE (512kb L2 Cache + 2MB L3 cache)
Intel Pentium 4 3.2C (Northwood, 512kb L2 cache)
|RAM:||2 x 512Mb OCZ 3500 Platinum Ltd
2 x 512Mb Mushkin PC3500 Level II
|Hard Drive(s):||Seagate 120GB 7200 RPM (8MB Buffer)|
|Video AGP & IDE Bus Master Drivers:||Intel Chipset Drivers|
|Video Card(s):||ATI Radeon 9800 PRO 128MB (AGP 8X)|
|Video Drivers:||ATI Catalyst 4.1|
|Operating System(s):||Windows XP Professional SP1|
|Motherboard:||Asus P4C800-E (Intel 875P - 478) Rev. 2.00|
It has been reported on other sites that the P4C800-E will not run the Prescott processor. We had no problem at all with the 3.2E Prescott on our P4C800-E. This particular board has been at AnandTech for about 2 months and is a late model Revision 2.00. Asus tells us that all versions of the P4C800-E will work fine with Prescott as long as BIOS is updated to version 1014 or later. You can find a CPU compatibility list for Asus motherboards at http://www.asus.com.tw/support/cpusupport/cpusupport.aspx.
All performance tests were run with the ATI 9800 PRO 128MB video card with AGP aperture set to 128MB with Fast Write enabled. Resolution in all benchmarks is 1024x768x32 unless otherwise noted. Results at 1280x1024 have also been provided where they are useful in comparing performance.
With the retesting required to compare Prescott, EE, and Northwood, benchmarks were updated with additional games and updates to other benchmarks.
Content Creation and General UsageWe have recently updated to the latest release of Winstone benchmarks. Veritest Multimedia Content Creation Winstone 2004 and Veritest Business Winstone 2004 are now the standard tests for system benchmarking.
Media EncodingDivx 5.1.1 has added support for additional extensions on both Intel and AMD processors. As recommended by both Intel and AMD, we have updated to Divx 5.1.1. We also updated to the latest XMpeg 5.03 as the front end for Media Encoding. Encoding is now benchmarked as a common dual-pass setup, so the results reported with XMpeg 5.03/Divx 5.1.1 are not comparable to earlier Media Encoding results.
GamesWe have added several new benchmarks to our standard Gaming tests. These include Halo, Microsoft's Direct X 9.0b game; Splinter Cell, a DX9 game; X2 Benchmark, a DX 8.1 game that includes Transform and Lighting effects; the DX9 Aquamark 3; and the DX 8.1 Comanche 4 benchmark. Since we have found that Comanche 4 can become video card limited at higher resolutions, we will only include benchmarks that run with 4X anti-aliasing enabled to differentiate system performance better using our standard ATI Radeon 9800 PRO video card.
We have dropped Yeti Studios DX9 Gun Metal 2 from our standard motherboard and system benchmarks, since there are many other DX9 choices now available that measure system performance variations better.
Heat and CoolingAll of our testing was done on air with Intel's stock CPU cooler supplied with the 3.2E. There is absolutely no doubt that Prescott gets hotter than either Northwood or Extreme Edition in our benchmarks. We did not measure temperatures, but the Heatsink felt much warmer during benchmarking Prescott. This was also the case with other HSF, like the Zalman 7000, OCZ Eliminator 2, and Thermalright SLK900. However, we never experienced a shutdown or throttle during several days of testing, and we did not have to use water-cooling to keep temperatures under control.
Our advice is to buy Retail with the Intel HSF or use only the best HSF with Prescott because it is definitely a hotter CPU than Northwood or EE. For those who will overclock, the Intel HSF is outpaced pretty quickly and you may need to consider water, phase-change, or other cooling methods. This should not be a concern for normal operation, however, since we had no real issues with the standard Intel heatsink.
