This is not strictly true. Many AVR chips can handle more computation than their clockspeed would suggest due to some really nice assembly codes that allow for common DSP calculations.

I ported an AVR code base to a cortex M4 last year, and some of the inlined asm didn’t translate. I ended up having to use inlined C instead. So, my 120Mhz M4 chip struggled to do what a 90Mhz AVR did no problem.

Note that it seems you're talking about AVR32, then, and not an 8-bit AVR like we were talking about.

AVR32 was neat, but has lost all commercial relevance.

Oh, yeah, good call. I guess I would be surprised to see significant DSP related asm in any 8 bit processor.
