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 are 512-bit extensions to the 256-bit Advanced Vector Extensions SIMD instructions for x86 instruction set architecture proposed by Intel in July 2013. [ 3 ] AVX-512 instructions are encoded with the new EVEX prefix .
AVX-512, introduced in 2014, adds 512-bit wide vector registers (extending the 256-bit registers, which become the new registers' lower halves) and doubles their count to 32; the new registers are thus named zmm0 through zmm31. It adds eight mask registers, named k0 through k7, which may be used to restrict operations to specific parts of a ...
Since then, there have been several extensions to the SIMD instruction sets for both architectures. Advanced vector extensions AVX, AVX2 and AVX-512 are developed by Intel. AMD supports AVX, AVX2, and AVX-512 in their current products. [5]
Intel released processors in early 2011 with AVX support. [7] AVX2 is an expansion of the AVX instruction set. AVX-512 (3.1 and 3.2) are 512-bit extensions to the 256-bit Advanced Vector Extensions SIMD instructions for x86 instruction set architecture.
Each core has two 512-bit vector units and supports AVX-512 SIMD instructions, specifically the Intel AVX-512 Foundational Instructions (AVX-512F) with Intel AVX-512 Conflict Detection Instructions (AVX-512CD), Intel AVX-512 Exponential and Reciprocal Instructions (AVX-512ER), and Intel AVX-512 Prefetch Instructions (AVX-512PF). Support for ...
AVX-512 are 512-bit extensions to the 256-bit Advanced Vector Extensions SIMD instructions for x86 instruction set architecture proposed by Intel in July 2013, and released on 2016 with Knights Landing, and in 2017 on the HEDT and consumer server platform, with Skylake-X and Skylake-SP respectively.
Predicated SIMD - also known as associative processing. Two notable examples which have per-element (lane-based) predication are ARM SVE2 and AVX-512; Pure Vectors - as categorised in Duncan's taxonomy - these include the original Cray-1, Convex C-Series, NEC SX, and RISC-V RVV. Although memory-based, the CDC STAR-100 was also a vector processor.
