Hmmm, there are only two desktop processor vendors. Is AVX-512 at all available on mobile?
From the two desktop vendors AMD has AVX-512 support on all their AM5 CPUs. Intel has support of AVX-512 on all 11th gen CPUs and on some 12th gen CPUs. The supports is there in the silicon on all P-cores in 12/13th gen CPUs, just disabled in microcode.
So AMD and Intel have already paid the cost.
- ben-schaaf 3y agoAMD - until AM5 - has not been willing to pay the cost. Intel was not willing to pay the cost for their E-cores. AVX-512 is almost 10 years old at this point and because of adoption issues still can't be relied upon.
- adrian_b 3y agoPreviously Intel had AVX-512 support in 3 generations of mobile CPUs, Cannon Lake U, Ice Lake U, Tiger Lake H/U, but only the last generation had widespread availability. Starting with Alder Lake, Intel has dropped the AVX-512 support in non-server CPUs. On the other hand, AMD has just launched their Phoenix mobile CPUs (Ryzen x 7x40 HS or U), which have excellent AVX-512 support.
