SiS 645: Pentium 4 DDR - Take II

Business & Content Creation Application Performance

It's been with us since the start and we continue to use it; Winstone has always been a great benchmark as a way of measuring performance as seen through the eyes of the normal user that is bound by the same I/O limitations (HDD performance) as everyone else.

Office Application Performance Business Winstone 2001 SiS 645 (DDR333) SiS 645 (DDR266) Intel 850 (PC800) VIA P4X266 (DDR266) 54.6 53.5 53.2 48.1 | 0 | 11 | 22 | 33 | 44 | 55 | 66

If we say that the only significant performance advantages are those above 10% we can conclude that the SiS 645 does have a significant performance advantage over the P4X266 as it is 11% faster in DDR266 mode. Switching to DDR333 buys you another 2% performance improvement which is pretty much unnoticeable. The Intel 850 is pretty much as fast as the SiS 645 with DDR266 SDRAM.

Content Creation Performance Content Creation Winstone 2001 SiS 645 (DDR333) Intel 850 (PC800) SiS 645 (DDR266) VIA P4X266 (DDR266) 72.6 72.4 70.7 64.8 | 0 | 15 | 29 | 44 | 58 | 73 | 87

Content Creation Winstone is a bit less disk limited than Business Winstone and thus stresses difference in memory bandwidth even more. Here we only have a 9% advantage when comparing the two DDR266 contenders, but the Intel 850 moves up a notch to be on par with the DDR333 equipped SiS 645.
