Re: Why is Athlon some much faster in Linux?...

It's not Linux, in particular. Athlon is much faster, per clock, in 95% of software. Intel has bought off then manipulated all commercial benchmarking groups (Bapco, SPEC, etc) to get them to tailor their benchmarks to the 5% of software that is simplistic enough so that it doesn't choke on P4's overlong pipeline.

Virtually any "real" application runs at roughly the same speed on a 1.2GHZ Athlon 4, a 1.4GHZ Athlon, and a 1.8GHZ P4. We've seen these results over and over again from independent sources like Anandtech, Aces Hardware, and ChipOnline. "Older" software runs at about the same speed on a 900MHZ PIII, a 900MHZ Athlon, and a 1.8GHZ P4.
