and that decision kills Alder lake for me and my org. We've had 5 years to optimize libraries for AVX-512 (since launce of the 79xx on X299 and corresponding Xeons) and are now able to get great performance at acceptable power consumption and are able to run on Sky lake, Ice lake and Tiger lake CPUs (even on laptops). With the AVX-512 fuse off decision on consumer CPUs, intel kills all this code and all gains (regressing to AVX2).
So the hope now goes to Sapphire Rapids and that there will be competitively priced HEDT CPUs and corresponding laptops parts (W series), and that potentially AMD's AVX512 implementation hopefully reaching consumer grade CPUs. but the potential to target a broad roll out to all modern consumer grade CPUs is gone.
