The whole architechture is just better. Although it will be changing in the future, up untill now games have rarely used more then 4 cores and have relied more upon IPC and single threaded performance. These are two areas where the current amd architechture lacks performance.

When people say that the 3570k/4670k will not be worth having in a few years they are wrong. Even if a game used 8 cores, the 4 cores of the i5 are still miles ahead in terms of performance per core.

I agree. I have a quad-core Athlon II, and it was at least as good as a tri-core Phenom that my grandmother's computer has. Also, this link says that my particular Athlon gets a benchmark score of 3500 compared to a range of 1500 to 2000 for various Phenom II x2's.

I think it's architecture too. Intel is always introducing new concepts to CPUs, and then AMD catches up, so it's more likely little tweaks that AMD hasn't caught up to yet.

This was a very good article. I had no idea that the DirectX API took care of threading. I thought that was up to the programmer. I'm glad I have a quad-core.
