For any heavy math program the PIII is another order of magnitude better. A few sample timings: op 8088 cycles Push register 11 Jump Not Equal 4 or 16, depending on if the branch was taken increment reg 3 AND reg,reg 3 16 bit multiply 118(reg*reg) 16 bit divide 165-184(reg/reg) I havn't done assembly langage programming in a decade, so I can't give the PIII timings. I expect that they can do any of these in 0.5 to 1 cycle, except for the branch instruction, which can cost a lot of cycles if it is predicted wrong. Angrim
