Bob, it actually works-out to be about "right" at that speed. The clincher here is the algorithm and the domain, i.e. required output. At work we (software) had a contest with the hardware dudes, who were using FPGAs (and what-have-you) ... and outcome was that in some of the cases (less than %20) the G5 won against the best FPGAs you can buy. Best Regards, Hristo p.s. The Apple claim is easily verifiable because you can download their example applications and test it for yourself; FIR, FFT work very well under Altivec. The problem, obviously. is that this speed doesn't apply to every problem (situation).
