In _Programming the 65816_ by Lichty and Eyes, there is a comparison of the speeds of a 4Mhz 65816, a 4.77(?)Mhz 8088, a 4Mhz 6502 and a 8Mhz 68000. The tests were conducted by running an assembly language version of the sieve of erastosthenes. I forgot the exact results, but the 65816 was more than 2 times faster than the 6502, and about 3(?) times faster than the 8088. The 68000 was 4 times faster than the 65816. If someone has the book, maybe they could post the exact results. If my memory is correct, though, it would seem that a 1Mhz 65816 would be faster than a 4.77Mhz 8088. -- David Huang | Internet: ifar355@ccwf.cc.utexas.edu | "My ganglion is stuck in UUCP: ...!ut-emx!ccwf.cc.utexas.edu!ifar355 | a piece of chewing gum!"
