NASA G5 v PC speed comparisons

It seems NASA thinks that G5s are pretty fast, and they're independant

Well, yeah, of course it matters. However, it's not the only thing that
matters when comparing processor performance. Still, at its rawest, the
basic idea with processor speed is (size of data) X (CPU frequency).

Within a chip family, of course. But the 2Ghz G5 Mac running with
G4-optimized code doing scalar computations managed to match a
2.66Mhz Pentium4, and the G5 had significantly higher MFLOPS/Mhz than
the G4 and Pentium.
