Can't argue with that, however, I would point out that you can do MPEG
video encoding on a P3-400MHz system at 320x240 resolution in true colours,
and that's *with* a 16 bit stereo audio stream and no hardware encoder (my
450MHz manages 16fps unassisted). I still find it hard to believe that a
machine that can manage that wouldn't be able to do ATRAC encoding fast
enough.

At a guess I'd say 35 MHz with 70MHz on-chip....
