Dear Tench: The only fp benchmarks that Cmine is quicker is the dirty SPEC. When compiled by standard compilers, and Intel is not a standard compiler, Cmine loses 1568MHz (2 x 784MHz) to a single 700MHz Athlon (See QMC benchmarks). VFC 4.5 (Intel) failed to compile QMC benchmark (see Tim Willkin's scientific benchmark page). Unless I see Willie benchs by third parties using current standard compilers beating Athlons, all you have is rumors. I still think that the only publically verifiable benchmarks are those whose code, compiler, and OS are public domain. Given this, the type of benchmark shenanigans that go on (on all sides) will go up in smoke. Scientific (and public) review will separate the good from the hype. If some hardware vendor wants to prove that theirs is better, they must submit, publically available source code for the benchmark program, compiler, and OS. They could simply say use an already written benchmark, say QMC, on a compiler, say gcc, on an OS, say Red Hat Linux, using the following makefile. If they want a different code generator in the compiler, they submit the public source code required to change it. Any special fix in the compiler is available to all the competitors as well. For CPU manufacturers, the validity of this method will allow the playing field to be level and the scores to be much more forceful and useful. Their will be no rocks to hide with or under, the customers can rely on time tested benchmarks, the Manu. of CPUs, Memory, Chipsets, and other hardware can have a PR bonanza, and the competition will advance knowledge for everyone. By the way, the resulting code could build diagnostic sets for determining and fixing system performance problems for the casual user. Pete
