Mac claims its G4 chip is faster than a Pentium of similar speed because it processes more bits per cycle or something like that. <UL TYPE=SQUARE> <LI>If this is true then how much faster? For instance, how does a 400mhz G4 compare to a 600 mhz Pentium III etc?<p> <LI>Also, assuming the PC based version of 001 ever comes out, what will you need in a PC to make it comparable to a G4.[/list]Please help a poor novice. Thanks.
craig- The general thing to remember when it comes to any claim of speed or performance is that such claims may or may not translate into a real-world benefit for the end user. Individual benchmarks can and have been tailored to reflect well on some systems, and (believe it or not) processors have on occasion been optimized for particular benchmarks. The problem with that is that the optimization doesn't necessarily boost the performance of any real-world application, just the benchmark. So the upshot of this is that a computer is not just a processor, but a very complicated system of hardware and software, every piece of which can affect performance. I'd use benchmarks and performance claims as guidelines and suggestions, no more. The only way to determine which system is best suited for your particular tasks is to try them out for yourself. As lwilliam pointed out, one CPU's strong suit may not be the thing you'll be needing most. Having said that, yeah: the G4 is technically faster than a Pentium of the same speed if you consider both in a vacuum. Right now, anyway. But a CPU in a vacuum isn't very useful. Much less in a vacuum cleaner. Er. Anyway, because of all the variability in software and hardware, it's hard to predict what you'll need in particular for PTLE in a PC. By the way, I believe the AltiVec unit can be used for both integer and FP operations. But it's really only useful when you need to perform the same operation on several numbers at once, as you do frequently with graphics and vector math. So leveraging it for 3D transforms and bitmap graphics is a no-brainer, but figuring out the best way to use it for audio is a little tricker. That's my guess, anyway. Still, vectors are handy things...
