There is no real way to know how it will stack up against the G5 as it has not been released yet only engineering sample. Be patient and we will all see how it performs.
Apples and oranges, I will be happy with a *portable* PowerBook that is SMP and can actually come close to a clunky Powermac that guzzles electricity like a SUV does to gasoline...
Initial benchmarks do show the performance to be neck to neck.. I foresee the entire Powermac line going quad once these monsters start shipping.
That fast!? My god.... it's sounds just...so....incredible....
Gonna make my 1.2 GHz G4 look like a 386. Damn you Apple, I don't have anywhere near the money for a new system. I just hope 10.5 will run nicely on my machine when I bump it up to 1.25GB RAM.
