Sneak Peek at 800MHz FSB Performance

There are a few interesting things to take away from this chart; for starters, dual DDR333 performance is better than dual DDR400 performance, which absolutely isn't the case you'll see with the 865/875 chipsets assuming you're using fast DDR400 memory. This should give you an idea that the SiS 655 obviously isn't optimized for dual DDR400 operation, much less 800MHz FSB operation, but again, that's why this is a preview.

As you would expect, the 800MHz FSB doesn't increase performance tremendously under office applications, mainly because we're not FSB/memory bandwidth bound in these cases.
