Everybody loves benchmarks, so here's some pitting several AmigaOne models, the Pegasos board and an AMD Athlon XP 1800+. The AmigaOnes where running Linux and none of the tests where optimized for AltiVec.
AmigaOne benchmarksNot surprisingly the Athlon comes out on top in most tests, though AmigaOne G3/1Ghz does better in several tests. Down at the bottom the A1 G3/600Mhz and the Pegasos duke it out for last place, it's odd how there seem to be small variations between what should be the same kit.
The real test will come when these tests are run under OS4- I think losing the Linux baggage might give it a bit of an extra push. And maybe using AltiVec too on the G4...
...then again you know what they say about statistics and benchmarks...
