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.

The x86 is bigger requires twice the clock speed, generates 4 times the heat do do the same amount of work as the PPC.
This isn't true for (at least) P3s, Athlons, Pentium Ms or P4s, except in a few *very* specific cases, so which x86 CPUs are you thinking of ?
They may be about the same speed, but the PPC has a lot more room to grow.
I remember this being said about PPC and x86 once before, about a decade ago. Since then, PPC processors had the better performance of the two for less than a year, around the release of the first G4s,
Intel have a much better track record for delivering than any of the members of the AIM alliance.
