I mean, 288-E Core Xeons are about to ship. Xeon 6900 series, right? (Estimated to ship in Q1 2025) So Larrabee lives on for... some reason. These E cores are well known to be modified Intel Atom cores and those were modified Xeon Phi cores which were Larrabee based. Just with.... AVX512 being disabled. (Lost when Xeon Phi turned into Intel Atoms). Intels technical strategy is completely bonkers. In a bad way. Intel invented all this tech 10 to 20 years ago but fails to have a cohesive strategy to bring it to market. There's clearly smart people there but somehow all the top level decisions are just awful |

Ironically, AMD waited so long to implement AVX-512, but now has it on both server and mobile chips (natively and 256 bit emulation, respectively). Intel started the whole thing, has a very fragmented stack and is now preparing those E cores with even more new extensions.
Most importantly for Search and AI, it adds AVX_VNNI, which can be used for faster 8-bit integer dot-products: https://github.com/ashvardanian/SimSIMD/blob/75c426fb190a9d4...
Would be interesting to see how matrix multiplication throughput will differ between AVX-512-capable P cores and a larger quantity of AVX_VNNI-capable E cores!
