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. [1] [2] Bulldozer is the codename for this family of microarchitectures. It was released on October 12, 2011, as the successor to the K10 microarchitecture.
The XOP (eXtended Operations [1]) instruction set, announced by AMD on May 1, 2009, is an extension to the 128-bit SSE core instructions in the x86 and AMD64 instruction set for the Bulldozer processor core, which was released on October 12, 2011. [2] However AMD removed support for XOP from Zen (microarchitecture) onward. [3]
The AMD Lightweight Profiling (LWP) feature was introduced in AMD Bulldozer and removed in AMD Zen. On all supported CPUs, the latest available microcode updates have disabled LWP due to Spectre mitigations. [31] These instructions are available in Ring 3, but not available in Real Mode and Virtual-8086 mode. All of them use the XOP prefix.
Advanced Micro Devices (NYS: AMD) has introduced the first processors based on the Bulldozer chip architecture, under the FX product banner. Sporting as many as eight processor cores per chip ...
Bulldozer is designed for processors in the 10 to 220 W category, implementing XOP, FMA4 and CVT16 instruction sets. Orochi was the first design which implemented it. For Bulldozer, CPUID model numbers are 00h and 01h. AMD Piledriver Family 15h (2nd-gen) – second generation Bulldozer (First optimisation). CPUID model numbers are 02h (earliest ...
AMD FX are a series of high-end AMD microprocessors for personal computers which debuted in 2011, claimed as AMD's first native 8-core desktop processor. [1] The line was introduced with the Bulldozer microarchitecture at launch (codenamed "Zambezi"), and was then succeeded by its derivative Piledriver in 2012 (codenamed "Vishera").
AMD Excavator Family 15h is a microarchitecture developed by AMD to succeed Steamroller Family 15h for use in AMD APU processors and normal CPUs. On October 12, 2011, AMD revealed Excavator to be the code name for the fourth-generation Bulldozer-derived core. The Excavator-based APU for mainstream applications is called Carrizo and was released ...
^ All models support AMD Turbo Core, v2.0 for BULLDOZER and v3.0 for PILEDRIVER. ^ The clock multiplier is applied to the 200 MHz HyperTransport base clock. ^ A line of Socket F and Socket AM2 processors launched in 2006 were named Athlon 64 FX, the first being the AMD FX-60.
