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.

First off, HT (Hyper Threading) is a form of SMT (Simultaneous MultiThreading), so stop all this nonsense of HT vs SMT!

Second neither IBM nor DEC (with their EV8) ever claimed 100% performance increase of a SMT implementationg vs. non SMT of the same architecture.

I also have a few bones to pick with the author, since he makes a lot of false claims, for example:

"The amount of voltage the CPU can use restricts the power available and this effects the speed the clock can run at, x86 CPUs use relatively high voltages to allow higher clock rates, "

This statement is so wrong, that I do not where to begin with the nitpicking! phew...
