Which pic or avr is faster (by Olivier)
I need an application where i control phase angle on 120hz (8.3ms that i need to divide in at least 100) , so i need a cycle time less than 0.1 ms, with pic it gives cycle time too fast error, can i get better speeds with atmega even if it has a 16mhz oscillator

(no subject) (by Jonathan Westhues)
The AVR processors are 1 MHz/MIPS, but the PICs are 4 MHz/MIPS. So e.g. an AVR at 16 MHz executes 16 MIPS, but a PIC16 at 20 MHz executes only 5 MIPS.

It's a bit more complicated, since the same operation may require a different number of PIC vs. AVR instructions, but an AVR will generally be ~4x as fast as a PIC with the same clock.
