My new athlon XP system just got fried..

I have some questions. I've heard the Athlon64 3200+ can beat a P4 3.2 EE in
most tests. Is this true, and is there any reason why one would buy the P4
over the A64 other than bias?

I when I compared my Dell P4 3 GHz Hyperthreaded PC3200 dual channel at
work with my HP Athlon64 3200+ (2GHz) PC3200 single channel at home, the
P4 beat the AMD64 in all Sandra math, multimedia, and memory tests. Yet
3DMark03 results with the same exact video card (FX 5700LE) were faster on
the AMD64. But it is not a fast enough video card to be cpu limited.
Bumping up HTT 10% on the 1g cache AMD64, which bumped cpu to 2.2 GHz, RAM
to 440, PCI bus (everything except AGP), bumped Sandra scores 10%, but had
almost no effect on 3DMark03 or Doom3 timedemo.

So maybe my AMD64's 1200 MHz FSB with 400 MHz interleave RAM is close to
P4's slightly faster math, 800 MHz FSB and dual-channel RAM in certain
tasks. Note that P4 RAM access in this case was only 68% efficient vs.
95% for the AMD64. So 1200/800 = 1.5 AMD vs. 68 * 2 / 95 = 1.43 P4
plus its math advantage which varies by test.
