Toms’ Hardware has been looking under the bonnet of AMD's Zen 5-based Ryzen 9000-series processors and discovered that they handle AVX-512 instructions with minimal speed reduction and power increase, ...

In context: Advanced vector extensions are a type of "single instruction, multiple data" extension to the x86 instruction set architecture, implemented by Intel and AMD in modern CPUs. These ...

As chip technology advances over time, new instructions can be added to a given architecture. A key is to make sure that these systems are backward compatible, that older applications can still run, ...

Intel AVX-512 is the latest in a long history of x86 vector instruction sets. Vector instructions, commonly known as SIMD instructions, are special because they do more than one operation at a time.

For the majority of workloads, fiddling with assembly instructions isn’t worth it. The added complexity and code obfuscation generally outweigh the relatively modest gains. Mainly because compilers ...

Single-instruction, multiple-data (SIMD) instructions that can process multiple data with one instruction greatly contribute to the speedup of CPU operation. However, since SIMD instructions require a ...

Intel has warned that it is about to release its AVX-512 instructions which it claims will offer the highest degree of compiler support by including an unprecedented level of richness in the design of ...

First, architecture basics are detailed with information on the register sets, data types, and memory and instruction formats. Next, instruction set extensions are detailed, which include Intel® ...
