I did a consultancy report comparing 6502, Z80 and
6802, the project
was for a Torque, Speed and Power measuring system that had a PWM
input from the transducer to an analogue out 200 times a second, I
dont have the paper doc any more but the 2 meg 6502 beat the Z80 and
6802, everyone at the time would mention the clock rate of the Z80
claiming it was faster, they never notice the clock is divided, basic
instruction rate was about 1 meg on the Z80.
True, but on an original 6502, the clock rate is only 1MHz. The 2MHz
version is a 6502A :-)
In fact the 6502 was part of the inspiration for the ARM chip.
