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 is supported in Intel's Knights Landing processor. AVX-512 is not the first 512-bit SIMD instruction set that Intel has introduced in processors. The earlier 512-bit SIMD instructions used in Xeon Phi coprocessors, derived from Intel's Larrabee project, are similar but not binary compatible and only partially source compatible.

AVX-512 consists of multiple extensions not all meant to be supported by all processors implementing them. Only the core extension AVX-512F (AVX-512 Foundation) is required by all implementations.

Instruction set

The AVX512 instruction set consists of several separate sets each having their own unique CPUID feature bit, however they are typically grouped by supporting processor generation.
