AVX-512 Foundation (F) – expands most 32-bit and 64-bit based AVX instructions with the EVEX coding scheme to support 512-bit registers, operation masks, parameter broadcasting, and embedded rounding and exception control, implemented by Knights Landing and Skylake Xeon
AVX-512 Half-Precision Floating-Point Instructions (FP16) – vector instructions for operating on floating-point and complex numbers with reduced precision. Only the core extension AVX-512F (AVX-512 Foundation) is required by all implementations, though all current implementations also support CD (conflict detection).
AVX-512: 512-bit vectors, operating on zmm0..zmm31 registers (zmm0..zmm15 are extended versions of the ymm0..ymm15 registers, while zmm16..zmm31 are new to AVX-512). AVX-512 also introduces opmasks, allowing the operation of most instructions to be masked on a per-lane basis by an opmask register (the lane width varies from one instruction to ...
Then, for each of 4 consecutive AVX-512 registers, they will, for each 32-bit lane, interpret the lane as a two-component vector (signed 16-bit) and perform a dot-product with the corresponding two-component vector that was read from memory (the first two-component vector from memory is used for the first AVX-512 source register, and so on).
Xeon Platinum, Gold 61XX, and Gold 5122 have two AVX-512 FMA units per core; Xeon Gold 51XX (except 5122), Silver, and Bronze have a single AVX-512 FMA unit per core-F: integrated OmniPath fabric-M: 1536 GB RAM per socket vs 768 GB for non-M SKUs (2 memory controllers per socket vs 1 for non-M SKUs)-P: integrated FPGA
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 in 2016 with Knights Landing, and in 2017 on the HEDT and consumer server platform, with Skylake-X and Skylake-SP respectively.
Zen 4 is the first AMD microarchitecture to support AVX-512 instruction set extension. Most 512-bit vector instructions are split in two and executed by the 256-bit SIMD execution units internally. The two halves execute in parallel on a pair of execution units and are still tracked as a single micro-OP (except for stores), which means the ...
