AMD Zen 5 architecture will support a variety of new instruction sets to further enhance AI performance

News from this site on February 11, according to Phoronix, the new version of the GNU Compiler Collection (GCC) has provided preliminary support for the upcoming AMD Zen 5 architecture, and confirmed that the Zen 5 processor will introduce at least 5 new instruction sets , such as AVX-VNNI.

This site noticed that 4 of these 5 new instruction sets have already been introduced on Intel CPU, and another instruction will soon appear on Intel Granite Rapids server CPU. AMD has not paid as much attention to instruction set support as Intel, especially AVX related instructions.

Public information shows that AVX-VNNI is an instruction set introduced by Intel for Alder Lake CPU in 2021, where VNNI stands for Vector Neural Network Instructions. In today's AI-centered It is extremely important in the environment.

It should be noted that AVX-VNNI is different from AVX512-VNNI. AVX-VNNI is relatively weak, but both instructions can perform the same operation, and AVX512-VNNI can use 512bit vector sum EVEX extensions for better performance.

Currently, Zen 4 already supports the AVX512-VNNI instruction set, so it does not seem to make much sense whether AVX-VNNI is supported or not, but at least it is meaningful for consumer-level processors, and Intel has done it before Lived the same thing.

The above is the detailed content of AMD Zen 5 architecture will support a variety of new instruction sets to further enhance AI performance. For more information, please follow other related articles on the PHP Chinese website!
