I daresay that the PII is turning more than 10 MIPS (any guesses? > How many clocks per instruction does a PII use, under average workloads?),
Other way around. Modern processors are in instructions per clock. On raw CPU power it doesn't just beat the mainframe - it steamrollers them. Your I/O bus is typically PCI however so you are limited to about 100Mbytes/second I/O throughput in the real world.
