SpecFP and the mighty clouds of joy - For all of us trying to pierce the fog around those stunning CUmine benchmarks, JC's page jc-news.com has a very interesting message from a fellow doing some scientific simulation work. He modified his heavily floating point oriented code, running on an Athlon 500, to use the SSE prefetch instructions and voila! Up to 45% increase in performance on data-sets of similar size to those used by SpecFP. So the mystery remains: what will the actual performance of 733 CUmine look like? If Intel's assertion, as reported by Ten, of ~20% imp over PIIIB holds, then the Athlon will be in trouble on many benchmarks. If, on the other hand, the bulk of the improvement was due to compiler-optimization, then the picture is much brighter for AMD. We have all had a couple days to ponder, what do you think? (I consider the estimated 266 FSB scores to be fighting today's fire with tomorrow's rain; I am mostly concerned with Athlon 700 performance on Oct. 25.)

Vacillating,

Vince
