Chuck Moore - CTO of Technology Development at AMD - has indicated that the new Bulldozer x86 architecture is basically two quad cores stitched together. Bulldozer has two quad cores with an integer scheduler, which share two FPU 128bit FMAC schedulers.
Each int scheduler quad has a dedicated L1 cache, which interacts with an L2 shared cache used by both cores and FPU units. The final layer has shared L3 cache as well as Nortbridge support. The CPU is designed to easily and efficiently interconnect with the system graphics, but this kind of product will not likely launch before 2012. AMD has stated that the Bulldozer and Bobcat chips have been designed with different usage models in mind, so expect one to significantly outpace the other at folding and other computationally intensive tasks.
Bulldozer is intended to provide AMD with an integrated CPU option for linking against GPUs in highly scalable, single-chip Accelerated Processing Unit (APU) configurations. Bobcat on the other hand will target the low power, ultra-power efficient PC markets. It will feature a tiny, highly flexible core that is also designed to be easily scaled up and combined with other IP in APU configurations.
The Bulldozer is tentatively planned for desktop and server market release sometime in 2011.
