The only change is in the memory prefetching. P2, K6, P1, 486 will not see any benefit - nor harm.

This version should be safe. I ran the torture test for two minutes on all FFT sizes from 40K to 4096K.

I'm surprised the Duron's tiny 64K L2 cache didn't cause more problems than it did. I guess the fact that AMD caches are additive, the Duron (64K L1 + 64K L2) acts more like a Celeron with a 128K L2 cache. I'm inclined to ignore the Duron's slowdown over 896K FFT as I imagine most Duron's are doing double-checking.

Thanks for the benchmarks. I don't own a PIII or Duron so I really needed those benchies.

So, George, you got that XP I sent you working??

Best time for 1792K FFT length 209.371 ms.

2048k line deleted, as there's nothing to compare it to.

I dunno why the CPU clock picks up differently - I didn't change anything between the tests. It's LOWER on the new version, though, and very minor - shouldn't affect the benches significantly.

ASUS A7V266, slightly overclocked due to CPU cooling limits (even Alpha 8045/Deltas have
some problem keeping a Palomino cool when the ambient is significantly above 80 F!) - I
normally OC this machine to 144 Mhz, but have had to down-clock a little since the summer
heat hit.

I'll be curious to see what my Thoroughbreds and the P-IV manage, as those are my fastest
machines - can't check the K5 and K6 and Celerons yet, as those are all Linux boxen.

ok, I'll be an early adopter. Just to play safe, I'll run a few hours of torture. It hasn't caused any funny stuff, i.e., cpu detected as normal.

btw with respect to durons, I do run first time tests, even the big 19M ones. That is, until the orphanage found a bonanza in the 12 - 13M range.
