The G5 was compared to the Xeon because you cannot get a duel P4.

Photoshop has always been faster on Mac's. X86 computers are just obnoxiously slow when dealing with images and video. In many cases My Amiga is still faster with video. It's just not what the x86 was made for. > >BTW, you mention Altivec. What makes you think IBM's implementation of Altivec >is any better than Intel's implementation of SSE2? Come on, this is common cense. Obviously Altivec makes for a bigger speed difference in the mass majority of applications than SSE2. If you doubt the usefulness of Altivec please read Nasa's G4 study. http://members.cox.net/craig.hunter/g5/NASA_G4_Study-1.pdf > >One also has to ask what in the world Jobs is doing up there, oh so happy about >having a 2GHz processor, when MHz don't matter. ;) It is called marketing, the only reason x86 has stayed the standard in home PC's. Apple has to take a shot at the perception game. Too bad Apple will gain very customer base from it anyway. > >-Tom Obviously there are plenty of tasks that even the x86’s on sale today can accomplish faster than the G5’s of tomorrow also. Does anyone really expect Apple to show those benchmarks? It won’t happen. Different CPU’s are intended for and are better at different tasks, so a straight across comparison will never be fair for both sides. Each company should be expected to show their best side. Intel and AMD do the same. -Ryan
