Thing is a fast clock doesn't necessarily mean a fast system.
I do a lot of designs with 100MHz ARM and a 16MHz AVR Mega can outperform it in some situations.

Could you please give an example. I do find it hard to believe a 100Mhz 
system is being overperformed by a
much lower speed 16Mhz. Perhaps the HW (UI,UART,CAN etc)  on the 16Mhz 
is perhaps faster or offers more
possibilities?
