Ali - Re: Everyone knows that it is performing exactly the same way as overclocked P-III, plus-minus 2-3%. Elmer would probably disagree again, and lose again :) If we look to the mobile processors for guidance, I believe the following is the benefit of 256kB on-die compared to 512kB half-speed: 7% SPECint 15% SPECfp 5% Winstone99 0% MultimediaMark 1% 3DMark99 CPU (source: Intel.com) Note that these are, of course, without the benefit of SSE (only the last two use SSE). I have been told (and seen benchmarks that tend to indicate) that SSE and 3DNow! are significantly more cache-dependent than normal operations (presumably because so many more numbers are crunched). Note also the massive increase in SPECfp, which when coupled with a 133MHz FSB and Rambus DRDRAM could well give the CuMine almost exactly the same SPECfp as the Athlon. --fyodor
