Bulldozer is designed from scratch, not a development of earlier processors. The core is specifically aimed at 10 to 125 watt TDP computing products. AMD claims dramatic performance-per-watt efficiency improvement in high-performance computing (HPC) applications with Bulldozer cores.
The Bulldozer cores support most of the instruction sets implemented by Intel processors available at its introduction as well as new instruction sets proposed by AMD.
