Intel to withdraw AVX512 support on Alder Lake-S

The launch of the Intel Alder Lake-S processors was undoubtedly one of the most important events of the year that we recently left behind. With this generation, the chip giant took an important step in terms of performance, and also efficiency, although in this sense it is necessary to highlight the role that the AVX512 support could play.

AVX512 instructions can make a significant difference in certain professional settings, but when used, the efficiency of Intel Alder Lake-S processors drops dramatically, and operating temperatures skyrocket. These instructions are also supported on processors Intel Rocket Lake-S, known as Gen11 (predecessors of Alder Lake-S), and on the chips Cascade Lake-X HEDT.

Due to this significant loss of efficiency, and the fact that AVX512 instructions do not play an important role in most cases, Intel is considering the release of a new firmware that would allow disabling support for these instructions on Core Gen12 processors. , that is, in the Alder Lake-S series. It would not be a badly calculated move since, in the end, these instructions make a difference in sectors such as cloud and high-performance computing, two levels where the chip giant’s Xeon solutions are typically used.

And speaking of the Xeon series, it is said that the AVX 512 instruction support will remain in the next generation HEDT processors that will be derived from the series. Sapphire Rapids, although we still don’t have much information about it. If this is confirmed, this new generation of HEDT chips will offer a clearer differential value compared to the Alder Lake-S.

We remind you that Alder Lake-S processors offer a high level of performance, both single and multi-threaded, and that thanks to the use of high-performance and high-efficiency cores, this generation is capable of offering much higher energy efficiency, especially when compared to the previous generation.
