Testbed and Methods

This testing session is about the performance of i925 and i915 chipsets with different memory types in contrast to that of i865/i875 chipsets. I took the following mainboards for my tests:

Intel D925XCV. This mainboard is based on the Intel 925X Express chipset. I used this mainboard to examine the performance of this chipset with dual-channel DDR2-533 and dual-channel DDR2-400 memory.

Intel D915PBL is based on the Intel 915P Express; it will help us estimate the performance of the chipset with DDR2 SDRAM.

ABIT AG8. ABIT made its i915P-based mainboard compatible with DDR SDRAM rather than with DDR2. This mainboard will help us evaluate the performance of the Intel 915P Express chipset with dual-channel DDR400 SDRAM.

ASUS P4P800-E Deluxe. This is an i865PE-based mainboard, but it matches the performance of i875-based products due to ASUS’ exclusive HyperPath technology. Note also that this mainboard can work with DDR533 SDRAM with the processor operating at its rated frequency, which makes it a most exciting object for comparison with the i925/i915-based boards.

I used the following hardware for my tests:

• Processors:
• Intel Pentium 4 3.4E GHz (Socket 478, Prescott core)
• Intel Pentium 4 3.4E GHz (LGA775, Prescott);
• Mainboards:
• Intel D925XCV (LGA775, i925X Express chipset);
• Intel D915PBL (LGA775, i915P Express);
• ABIT AG8 (LGA775, i915P Express, DDR SDRAM);
• ASUS P4P800-E Deluxe (Socket 478, i865PE).
• Memory:
• 1024MB DDR400 SDRAM (2-2-2-6 timings);
• 1024MB DDR533 SDRAM (3-4-4-8);
• 1024MB DDR2-400 SDRAM (3-3-3-10);
• 1024MB DDR2-533 SDRAM (4-4-4-12).
• Graphics cards:
• NVIDIA GeForce FX 5900 XT (390/700MHz);
• NVIDIA GeForce PCX 5900 (390/700MHz).
• Disk subsystem:
• Western Digital Raptor WD740GD.

I performed the tests in Windows XP SP1 with DirectX 9.0b installed.
