Meaningless Indicator of Performance?

MIPs is inversely proportional to clock spead. Neither is better than 
the other as a measure of performance except in the same generation (and 
revision) of CPU of the same architecture.

Mostly, but not necessarily, the big changes are at the generational 
changes: a Pentium III at 1 Ghz outperformed a Pentium IV at the same 
speed, and an Athlon outperformed both.


It gets even more complicated when comparing different architectures: 
choose amongst current generations of IA32, IA64, AMD-64, Power, 
UltraSparc, Sparc64, MIPS and ARM. And IBM's zSeries, which don't 
compute all that well, but do disk I/O at gigabytes/sec.
