But the FX moniker always disappointed
In my memory, the FX51 and FX53 where dual socket 3GHz ish Athlon X2s which were competing against the first core 2 and the Intel "two-chips in a box mashup" quad cores (a technique finally taken onboard in Magny Cours). And they lost.
My favourite review was XBitLabs who compared the IPC of Bulldozer with Thuban and Sandy Bridge where it only had 1/2 and 2/3 respectively. I wonder how well it would have fared against an E350.
Bulldozer is a core designed for server loads not as a desktop where software is poorly threaded. It would be a gross mistake to replace the Llano core with a bulldozer core. If AMD wants to compete on the desktop it needs to throw as many transistors into its core as it can: double the FPU and get a 5% speed increase, double the integer units and get another 5% etc. Bulldozer takes intelligent transistors out of the core and replaces them with dumb cache transistors. Going from 65nm to 32nm, AMD could fit 4 original Phenoms onto their die with 16 cores and 8Mb L3 cache, and it would probably be faster.
Over the last decade I've bought about 20 AMD CPUs and 2 Intel CPUs.
