Yes, though our prime interest is decoding (though people doing lots of
transcoding will want to look at encoding benchmarks, though ideally
mp2 to mp4 benchmarks.)   I see a much more dramatic difference there,
though some of it may also come from the better memory bandwidth I am
getting on my P4 system over my Athlon XP 3000 systems.  I don't know
if that's the chipset or the 800mhz FSB or the CPU or what.

A 10% difference for example, might lean you to the lower-heat Athlon.  However
I am seeing a much larger difference on the decoding which is what we
care most about, and would love to see other people's numbers, especially
for celerons and Athlon64s in 64 bit mode.
