Yeah, I think that's some salesmanship peeking through.  I got the 
impression he was moving along the thought process that 6502 can perform 
an activity in 1/4 the cycles as an 80XXX CPU, so for the same speed, 
the 6502 would be faster.  But, the Pentium of today is a far cry from 
the one in the past, and I highly doubt one can push more functionality 
out of a CPU that ARM or Intel does at a given clock speed.
