2.4GHz overclocked to 3.15GHz
v23.2 vs 23.3 vs 23.4

v23.4 can run even faster if I close some of my apps. Got quite a few apps running in the backgroud which I cannot be bothered to close when doing the benchmark :)

Versions 23.3.1 and 23.4.1.
I already reported the 23.3.1 results, just repeating them in this thread.

Just for kicks I tried benchmarking an Athlon XP 1800+. It seems most of the recent optimizations hurt the Athlon code path, but that's not too surprising.

I'd benchmark my 3.3Ghz P4 too, but I doubt that'd turn up any surprises.

All changes have been "neutral" on the Athlon. That is, the non-SSE2 code has not changed at all.

Yeah you're right, they're pretty consistent. I'd forgotten that v23 raised the top benchmark to 2048k.

S3SJK · 2003-05-24, 12:16

Maybe I'm just be as blind as a bat but where is V23.4 ?

Thanks
