SiS 648 - Taking Advantage of the P4 Situation

High End Workstation Performance - SPEC Viewperf 7.0

The latest version of SPEC Viewperf proves to be an excellent stress test for memory bandwidth and overall platform performance as you're about to see. The benchmarks included version 7 of the benchmark suite are:

High End Workstation Performance SPEC Viewperf 7.0 - 3DSMAX-01 Intel 850E (PC1066) SiS 648 (DDR400) SiS 648 (DDR333) VIA P4X333 (DDR333) VIA P4X400 (DDR333) SiS 645DX (DDR333) VIA P4X400 (DDR400) Intel 845E (DDR266) 3.845 3.751 3.747 3.727 3.727 3.667 3.344 3.015 | 0 | 1 | 2 | 2 | 3 | 4 | 5

There's a significant separation between the 850E and the slowest performing 845E in this benchmark, with a performance gap of over 27%. Once again we have the 850E and SiS 648 at the top of the charts, with VIA's P4X333 and P4X400 falling slightly behind. Also note that the P4X400 with DDR400 is slower than the same setup with DDR333.

Seeing as how the P4X400 is essentially a rebadged P4X333 chipset, the close proximity of the two motherboards in this test is expected.

The standings don't change at all in the DesignReview test.
