The 360/91, still in the punched card days, had a 60 ns cycle time. So that is 60 x 10^(-9) seconds per cycle or (1/60) x 10^(9) Hz or 17 MHz. Not so shab

It read memory 64 bits at a time interleaved 64 ways. And it had IRCC 8 locations of 64 bits each of an instruction cache. Some loops could fit in the cache at which time the machine would go into loop mode.
