AMD's Nervous Breakdown

So Bulldozer bombed. The biggest change in CPU architecture for AMD since the K7, and their one true hope for finally making up the miles worth of lost ground towards Intel in the processor performance race. Up in smoke.

Oh, it's a disappointment alright. On paper -- and granted, I'm not a whiz at processor architectures -- it sounded pretty darn good. Sure two threads had to share a single FP unit inside one of its modules, but it could do 256-bit vector operations. General consensus is that the design of the chip, from a high level, was sound. But it hinged on something very important: clockspeed. It was a beefier engine, and it needed more cycles to keep it fed, and the end product was simply starved of those. Unless you were following all the leaked benchmarks and performance indicators leading up to its launch, you were shocked. The world was shocked.
