Speaking in my professional capacity, I will tell you that phrases like "hyperthreading" are marketing terms. "Hyperthreading" is dependent on a number of factors, primarily the willingness of the game manufacturer to buy a proprietary compiler tailored to the hardware, at a very hefty price. That is, forget about performance improvements if your game was assembled using the universally available and free gcc compiler.

Also, CPU benchmarks are meaningless without knowing precisely how they were measured; I can write a program that will show higher numbers just by simplifying the tasks I'm counting.

I'm not even going to go into the irrelevance of internal CPU clocking, other than to say that memory and peripheral bus performance is way, way more important.

I sincerely doubt that the graphics chip is anything other than an OEM from one of the major manufacturers. Besides, my 21" monitor has over four times the resolution available from a TV.

That said, gaming consoles should consistently outperform PC's, simply because they are dedicated to one function. The problem I see is that they lack software portability.

PC's will keep the advantage because of the portability issue, and because of their ubiquity; everyone needs to have a computer, but a game console's just a toy.
