The five-volume set of the x86-64 Architecture Programmer's Manual, as published and distributed by AMD in 2002. x86-64 (also known as x64, x86_64, AMD64, and Intel 64) [ note 1] is a 64-bit version of the x86 instruction set, first announced in 1999. It introduced two new modes of operation, 64-bit mode and compatibility mode, along with a new ...
Advanced Vector Extensions 2 (AVX2), also known as Haswell New Instructions, [ 24] is an expansion of the AVX instruction set introduced in Intel's Haswell microarchitecture. AVX2 makes the following additions: expansion of most vector integer SSE and AVX instructions to 256 bits. Gather support, enabling vector elements to be loaded from non ...
AVX-512. AVX-512 are 512-bit extensions to the 256-bit Advanced Vector Extensions SIMD instructions for x86 instruction set architecture (ISA) proposed by Intel in July 2013, and first implemented in the 2016 Intel Xeon Phi x200 (Knights Landing), [ 1] and then later in a number of AMD and other Intel CPUs ( see list below ). AVX-512 consists ...
AMD was the first to introduce the instructions that now form Intel's BMI1 as part of its ABM (Advanced Bit Manipulation) instruction set, then later added support for Intel's new BMI2 instructions. AMD today advertises the availability of these features via Intel's BMI1 and BMI2 cpuflags and instructs programmers to target them accordingly.
3DNow! is a deprecated extension to the x86 instruction set developed by Advanced Micro Devices (AMD). It adds single instruction multiple data (SIMD) instructions to the base x86 instruction set, enabling it to perform vector processing of floating-point vector operations using vector registers. This improvement enhances the performance of ...
AMD's GPUOpen website hosts a PDF document aiming to describe the environment, the organization and the program state of RDNA devices. It details the instruction set and the microcode formats native to this family of processors that are accessible to programmers and compilers.
SSE4 (Streaming SIMD Extensions 4) is a SIMD CPU instruction set used in the Intel Core microarchitecture and AMD K10 (K8L).It was announced on September 27, 2006, at the Fall 2006 Intel Developer Forum, with vague details in a white paper; [1] more precise details of 47 instructions became available at the Spring 2007 Intel Developer Forum in Beijing, in the presentation.

AMD Athlon (early version), a technically different but fully compatible x86 implementation. x86 (also known as 80x86[ 3] or the 8086 family[ 4]) is a family of complex instruction set computer (CISC) instruction set architectures [ a] initially developed by Intel based on the 8086 microprocessor and its 8-bit-external-bus variant, the 8088.
