According to WDC, a 1 mhz 65C02 can do c. 500,000 8 bit instructions per
second. (Similar data on the 65SC816) If memory serves (wow, is that an
intro to fantasy land?) a 5 mhz 8088 does about 250,000 16 bit
instructions per second. Perhaps an 8086 in a 16 bit computer (remember
that the PC is basically an 8 bit machine except inside the 8088) would
do better, since it could retrieve code and data twice as fast. But, an
8 mhz 65C02 would be about a 4 mips machine. I honestly don't remember
how many mips a 16 mhz 80386 (SX or otherwise) would do. But comparing
mips isn't really a great gauge of how fast a computer is in real world
applications.
