Aren't you an old guy ?I really don't think AMD has ever came close to matching Intel's performance have they?
The Athlon line was pretty competitive until around when the 2.8+ GHz 478 P4s came out which started outpacing the XP's by a decent margin.
A64 were much faster than the Intel offerings and crushed the Pentium Ds until the C2D started coming out.
But it's been a long time since then.
