Here's a different opinion of AVX-512 (from: https://www.prowesscorp.com/what-is-...oes-it-matter/
). Just because it's useless to Linus Torvalds doesn't mean other people can't find a use for them.
Intel AVX-512 can accelerate performance for workloads and use cases such as scientific simulations, financial analytics, artificial intelligence (AI)/deep learning, 3D modeling and analysis, image and audio/video processing, cryptography, and data compression.
Intel AVX-512 can also help data centers more efficiently use available storage resources. Simply put, it accelerates storage functions, such as deduplication, encryption, compression, and decompression. It accomplishes this by doubling the number of bits in the register from 256 to 512 (see an illustrative animation here). In fact, it calculates storage functions in half the time of the previous generation.
This acceleration has a number of use cases:
63 times faster high-performance computing*
2 times faster AI/deep learning*
1 times faster cryptographic hashing performance*
2 times faster data protection*
This exceptional processing of encryption algorithms helps reduce the performance overhead for cryptography, which means you can deploy more secure data and services into distributed environments without compromising performance.
