You can build your own in an FPGA for something on the order of 2500 gates.
That will ostensibly operate at 80 MHz or so. Some vendors make claims
about their silicon that sport higher speed claims, e.g. 150-200 MHz.
I'll believe the 80 is realistic.

I was pointing out that is the processor was running fast enough even a
dog can look good. ;) Obviously using a 8mhz z80 as the standard your
comparison CPU had better be of similar generational speed or it may fail
the test. the inverse is with a 33mhz z185 I know I can blow the 65c02
out of the water unless someone has at least a 25-30mhz 6502!
