Indeed. I have a single Opteron 3400 that is cranking a measured 1.65
times better performance than my previous machine on doclifter, my
monster Python app -- which doesn't sound impressive until you
consider that the previous machine was a 2-processor SMP with 1.8GHz
Athlons. So my real-world throughput is as good or (allowing for
Amdahl's Law inefficiencies) better than what I'd get from a 6 GHz
Athlon, if such a thing existed.

That should do it. I expect the PPC to rise in importance rapidly over the
next two years, but I don't see anything other than x86_32, x86_64 and PPC
achieving significant market share.
