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: Mission critical

"Actually, the space shuttle computers use old x86 technology. We all know how that story ends. Maybe its time they update.
Maybe you should tell NASA about your theory the last shuttle crash was because of x86 processors and not a chunk of foam smashing a hole in the wing...
"
Duh... I realize that the crash wasn't because of the the processors. I only made a comment that x86 are, in fact used for mission critical applications. ANd that even the 8086 is still being used and sought after by NASA:
