the name of this "feature" is appalling

It has been widely reported that zen4 will finally add avx512, including leaked screen shots of an AMD manual. AFAIK there has been no public confirmation from AMD. There are probably enough engineering samples floating around at this point that we will know one way or the other soon. Avx512 complicates the decision as to whether or not to use a gpu for fp intensive code. It is a lot easier to change some compiler flags/add some code annotations than committing to debugging a cuda pipeline. Without fancy SIMD instructions, the choice of cpu is less relevant as the system will probably have one or more Nvidia gpus installed anyways.
