Talk, Rumors, X Versus Y This article started life when I was asked to write a comparison of x86 and PowerPC CPUs for work. We produce PowerPC based systems and are often asked why we use PowerPC CPUs instead of x86 so a comparison is rather useful. While I have had an interest in CPUs for quite some time but I have never explored this issue in any detail so writing the document proved an interesting exercise. I thought my conclusions would be of interest to OSNews readers so I've done more research and written this new, rather more detailed article. This article is concerned with the technical differences between the families not the market differences.

G4 = G3 + Altivec

"This was added in the G4 CPUs but not to the G3s but these are now expected to get Altivec in a later revision."

The G4 is simply a G3 with Altivec. Currently the G3 is the "consumer" processor while the G4 is the "Professional" processor. This is similar to the P4 vs Celeron.

Now that the G5 is around the G4 will become the "Consumer" processor.

I'm really not sure what role the G3 will have after the G5 ships but i wouldnt expect it to disapear untill apple gets a portable G5 on the market.
