Memory Subsystem Performance

This memory test produces most exciting results: the i865PE is the fastest here! That is, the low latencies of DDR SDRAM help this chipset to outperform the new i915/i925. Note also that DDR533 SDRAM permits to get even better results, although the i865PE hadn’t been originally designed to support this memory type. This test is also indicative of the less careful implementation of DDR400 SDRAM support in the i915P – this chipset works much slower with this memory than the i865PE.

Another synthetic memory test from the SiSoftware Sandra 2004 suite produces similar results.
