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.

re: 21064

The early generations of Alpha really took the RISC principles (read KISS) to the extreme. Maybe I'm thinking of the 21164 rather than the 21064, but I know that later generations (21364 and possibly 21264) started using things like instruction reordering that are less in line with the principles of RISC. The 21264 and 21364 were great designs, but they weren't as "pure" RISC as the earlier generations. EPIC takes the RISC ideas of letting the compiler do the work one step further (though I haven't seen any evidence that this is paying off yet).
