I believe the new Compaq ("DEC") alpha 667 MHz XP1000, based on the latest
alpha ("21264", aka by the project name of ev6 and, I think, ev67) is the
fastest on both integer and floating point.
The various 500 MHz 21264 alphas (264dp, XP1000, DS10, and DS20) are also
the fastest on floating point, and might be the fastest integer processors.
(The Intel chips are pretty fast on integer benchmarks, and it's hard even
for the alpha to stay clearly ahead of them.) The alphas certainly have
by far the fastest memory bandwidth.
Here are the approx SpecFP95 rankings...
9 typical x86 PeeCee
16 top-of-the-line x86 PeeCee
52 500 MHz EV6
67 667 MHz EV6
Or, Intel vs Alpha on SpecFP95 in blob graphics...
Typ X86 IIIIIIIII
Fast X86 IIIIIIIIIIIIIIII
