Well, yes, unless he's running in Thumb mode. 
Anyway, the ARM's instruction set does get a lot more done per 
instruction than the AVR, which, although being an 8-bit processor, 
is using 16-bit instructions.

I have not played so much with the ARM chips yet, so I'm not quite
sure of how code sizes look when ARM/AVR is compared. 
The GCC compiler for ARM is pretty bad at optimizing and cannot
compete with the AVR version. The IAR tools are pretty good though.
And, the ARM is obviously much faster.
