SPECviewperf

Those results prove that, under workstation conditions, i850 is still holding the lead over SiS645 with DDR333, but only a very small one. At the same time you can see that VIA's Apollo P4X266 seems to have some kind of problem in LIGHT-04 and DX-06, where it falls well behind SiS645 with DDR266 memory.

This test is a streaming benchmark and streaming applications want bandwidth. So it is not surprising to see i850 in the lead and SiS645 with DDR333 close behind.
