CLOCK SPEED BY ITSELF IS NEARLY IRRELEVANT. Also important is how many clocks a processor takes to get anything done. An 8088/8086/68000/32016 take 4 clock cycles to do a basic memory access. A 6502 (and, I assume, a 65816) take ONE. By this quick and dirty calculation the Apple IIGS is equivalent to a 12 MHz 8086. To get real, though, you also have to factor in the difference in power between the instruction sets, bus width, the degree of pipelining, etc... -- +----------------+ ! II CCCCCC ! Jim Cathey !
