I have build a cyrix system (again), this time withe an asus sp97-v (sis chipset). I like comparing systems in 3dmark99 max and everest benchmarks.
I went with the cyrix mII-300 cpu and clocked it to 3x75mhz=225mhz. The board is fit with edo ram and has 4x 16mb. I have no larger modules so 64mb is the max i can do.
Complete config:
At case and psu
Asus sp97-v
cyrix mII 300
64mb edo
3dfx voodoo1
s3 virge 2mb
4gb quantum bigfoot (a very slowwww BEAST!)
windows 98se
When running 3dmark with the voodoo1 it is slower compared to intel cpu's but nothing shocking and actual games (nfs1, nfs2, nfs3, sega rally) run at a playable speed.
When running everest it is painfully slow in fpu and memory write speed. Fpu is a known factor ofcourse but it is extremely slow i think. Memory write speed is simply aweful.
Memory read speed is exactly the same as the intel mmx (and a bit faster than the k6-2)
Memory write speed for the cyrix: 72mb/sec.
putting in an intel 166mmx with the exact same settings (except the multiplier is locked so it does 2,5x 75mhz= 187mhz) does 760mb/sec!!
putting in a k6-2 (3x75mhz again) gives 540mb/sec.
Even lowering the speed of the mmx cpu to 2x 50mhz fsb= 100mhz still gives 3x the write speed of the cyrix. Fpu tests are the same at this speed! (score of 9 for the cyrix@225mhz and 10 for the 166mmx@100mhz!!!)
Is my cyrix a bad unit? Or is it normal to be THAT slow? It is fast in integer but why is the memory write speed so slow?
Can anyone with a cyrix socket7 cpu at any speed run everest build 2253 for me and post results for the 3 fpu benchmarks and the memory speed tests?
VERY curious what other systems do.
