It is my pleasure to present the first detailed article on Bulldozer. I didn't get all the details I wanted (that is to say, everything), but it's certainly the most complete description of the microarchitecture available:

Altogether, Bulldozer looks to be quite interesting. But there are too many questions outstanding to determine whether they can match Sandy Bridge or not.

Hopefully over time I'll be able to fill in more details as they become available and confirm some of my educated guesses (or correct them).
