I would guess that the AVR would lead in arithmetic and RAM->RAM
activities, while the PICs would lead in I/O intesive operations. So you
should take great care defining a "real world" application, and even
more care interpreting the results.

BTW for true speed nothing beats an SX at 75 MHz (no /4) - OK, an SX at
100 MHz but those are no longer sold.
