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.

Yup, you are probably right. My main point was that the guy was pulling numbers out of his arse. Like I said in my original statement...

"though I have no doubt that Power5 SMT will provide more improvement than Pentium4 SMT"

The 100% improvement just sounded inflated to me. There are certainly cases where SMT will provide large performance increases, but we aren't talking about a 100% improvement in most cases.

RE SteveToth: Yup, you are right too. I never meant web-servers, but it looks like SMT/HT helps more for heavy computation tasks (scientific, multimedia editing, games possibly someday). Servers (web/database) in general are more I/O bound.
