Qualcomm Falkor (ARMv8 AArch64) vs Intel Broadwell and Skylake https://blog.cloudflare.com/arm-takes-wing/ Multicore AVX512 lowers the frequency The Qualcomm CPU only has the 128-bit wide NEON SIMD, while Broadwell has 256-bit wide AVX2, and Skylake has 512-bit wide AVX-512. This explains the huge lead Skylake has over both in single core performance. In the all-cores benchmark the Skylake lead lessens, because it has to lower the clock speed when executing AVX-512 workloads. When executing AVX-512 on all cores, the base frequency goes down to just 1.4GHz---keep that in mind if you are mixing AVX-512 and other code. |
