:How's your P4 for floating point? Is real-life perf as good as the :specbench numbers would indicate, or do you need a better compiler :than GCC to get any benefit from it? My wife is a statistician, and :she runs some really fp intensive workloads. This Athlon is faster :than the Serverworks box and (barely) faster than a year-old Alpha :UP1000 for her code. : :Drew : :------------------------------------------------------------------------------ :Andrew Gallatin, Sr Systems Programmer http://www.cs.duke.edu/~gallatin My understanding is that Intel focused on FP performance in the P4, and that it is very, very good at it. I dunno how to test it though. GCC generally does not produce very good code, but I would expect that it would get reasonably close in regards to FP because Intel's FP instruction set is a good fit with it. -Matt To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
