It has been months since AMD's Bulldozer architecture surprised the hardware enthusiast community with performance all over the place. The opinions vary wildly from “server benchmarks are here, and they're a catastrophe” to “Best Server Processor of 2011”. The least you can say is that the new architecture's idiosyncrasies have stirred up a lot of dust.</p>

Although there have been quite a few attempts to understand what Bulldozer is all about, we cannot help but feel that many questions are still unanswered. Since this architecture is the foundation of AMD's server, workstation, and notebook future (Trinity is based on an improved Bulldozer core called "Piledriver"), it is interesting enough to dig a little deeper. Did AMD take a wrong turn with this architecture? And if not, can the first implementation "Bulldozer" be fixed relatively easily?</p>

We decided to delve deeper into the SAP and SPEC CPU2006 results, as well as profiling our own benchmarks. Using the profiling data and correlating it with what we know about AMD's Bulldozer and Intel's Sandy Bridge, we attempt to solve the puzzle.</p>
