Cyrix Revisited: Do VIA's DDR S370 boards improve its performance at all?

[MadRat]

I'm curious.

I'm surprised this hasn't been brought up before.

Anand, can you help us out?

hmmm...interesting.

i'd like to know if the via ddr chipset works well w/ the cyrix processors as well...

it's probably never been considered since ddr, at the moment, is a high-end solution...cyrix, not.

 

[MadRat]

I'd like to know how flexible is that little jobby. It really hasn't been said if it works in dual boards, original S370, Intel 81x-family boards, etc. I'd like to see a good detailed review of the little sucker.

The problem is that the Duron 800 is cheaper than the Cyrix 700, and so much faster. Besides its low power dissapation, the Cyrix III looks like a pretty dead horse.

DDR doesnt help out the Cyrix 3 at all... the Cyrix3 really doesnt demand a whole lot in terms of memory bandwidth.

 

[BurntKooshie]

It's a single issue design. As stated, it requires beans for bandwidth. The on-chip cache is used to increase hit-rate, and lower latency, not for bandwidth.

More robust processors require high bandwidth, and low latency (low latency is always a good thing, and they need bandwidth because they can chew through so many instructions / cycle), and that's the other reason why chips have cache - one, because of spatial locality, it dramatically lowers average latency, and two, because it's cheaper to give smaller amounts of memory higher bandwidth (the same holds true for low latency).

 

[MadRat]

Why would single issue have anything to do with it?
