Tops != Tflops
Hz = cycles per second
ops = operations per second
flops = floating point operations per second
The 6502 ran at 1.023MHz, doing about 300 Kops, but only 1.7 Kflops.
It took 2-5 cycles per operation, and around 600 cycles to do a floating point
16-bit multiply or divide.
That's an extreme difference compared to today's pipelined architectures,
but you generally can't interchange flops and ops. Or Hertz, for that matter.
