![]() Only Bulldozer GEN4 ( Excavator) supports AVX2 instruction sets.Īccording to AMD, Bulldozer-based CPUs are based on GlobalFoundries' 32 nm Silicon on insulator (SOI) process technology and reuses the approach of DEC for multitasking computer performance with the arguments that it, according to press notes, "balances dedicated and shared computer resources to provide a highly compact, high units count design that is easily replicated on a chip for performance scaling." In other words, by eliminating some of the "redundant" elements that naturally creep into multicore designs, AMD has hoped to take better advantage of its hardware capabilities, while using less power.īulldozer-based implementations built on 32nm SOI with HKMG arrived in October 2011 for both servers and desktops. The Bulldozer cores support most of the instruction sets implemented by Intel processors ( Sandy Bridge) available at its introduction (including SSE4.1, SSE4.2, AES, CLMUL, and AVX) as well as new instruction sets proposed by AMD ABM, XOP, FMA4 and F16C. AMD claims dramatic performance-per-watt efficiency improvements in high-performance computing (HPC) applications with Bulldozer cores. The core is specifically aimed at computing products with TDPs of 10 to 125 watts. It was released on October 12, 2011, as the successor to the K10 microarchitecture.īulldozer is designed from scratch, not a development of earlier processors. ![]() Bulldozer is the codename for this family of microarchitectures. The AMD Bulldozer Family 15h is a microprocessor microarchitecture for the FX and Opteron line of processors, developed by AMD for the desktop and server markets.
