Elmer, Re:<They say Athlon should be able to execute the pre-fetch instructions from the Intel C/C++ version 4.5 compiler> Well, whoever suggests that is dumb. Intel would really have lost it if they shipped a compiler that illustrated the strengths of Athlon.

Elmer re...<<<<<When Intel intro'd Willamette at a far higher speed than Athlon, it was put up or shutup time for AMD, they chose to shutup. >>>>>>>> Elmer, if amd did shut up, why did AMD take on Willy with its Thunderbird, and guess who won the award for best processor at Cebit. Both were there, both were judged, Athlon won best of show. Who shut who up in their first head to head competition.

Elmer, re: <<"Only if Intel open source it will you get anyone to accept benchmarks from code built with this compiler.">> Elmer:<That's not what people here have been whining about. They say Athlon should be able to execute the pre-fetch instructions from the Intel C/C++ version 4.5 compiler and without those instructions that's why CuMine kicks Athlons but so badly in SPECint & SPECfp. They want a head to head comparison using the same compiler. Now they can have it along with prefetch.> I don't think the prefetch instructions in Athlon and Coppermine or bit-by-bit identical, although they may be very similar and perform the same functions. Anyhow, I expect the runtime libraries and DLL's for the Intel compiler check the processor ID info before allowing use of the prefetch instructions. So I don't think the Intel compiler will be useable for generating optimized Athlon code. The only advantage I see is that AMD can check for any blatant tricks in the compiler, such as substituting hand tuned assebly code for SPECint and SPECfp benchmarks when source code is recognized. If Microsoft is really using Athlon in X-Box, I expect that Visual C++ 7.0 will generate optimized Athlon code. Petz
