AMD BullDozer processors to launch on OCT 12 2011

Bulldozer is the codename Advanced Micro Devices (AMD) has given to one of the next-generation CPU cores after the K10 microarchitecture for the company’s M-SPACE design methodology, with the core specifically aimed at 10-watt to 125-watt TDP computing products. Bulldozer is a completely new design developed from the ground up.  AMD claims dramatic performance-per-watt improvements in HPC applications with Bulldozer cores. Products implementing the Bulldozer core were originally planned for release during the second quarter of 2011.

The Bulldozer cores will support most of the instruction sets currently implemented in Intel processors (including SSE4.1, SSE4.2, AES, CLMUL, and AVX) as well as future instruction sets proposed by AMD (XOP and FMA4).

The higher end models has 8 cores and they are FX-8170, FX-8150, FX-8120 and FX-8100. These models have 8MB L2 cache and is 125W  TDP. The FX-6120 and FX-6100 are 6 cores with 6MB L2 and FX-4120 and FX-4100 are 4 quad cores with 4MB L2 Cache. The hex cores and quad cores are all 95W TDP. All models support memory of 1866MT/s. They are all multiplier enabled and supports turbo cache. It fits existing AM3+ AMD 990FX boards and they are on 32nm SOI manufacturing process. The processor speed information can be found tabulated below.*
