It depends on the CPU type (bronze/silver < gold/platinum). My workstation saw 1.4-1.6x end to end application speedups, including throttling (even on multiple cores) for JPEG XL decoding and vqsort. [ General observation, not directed at parent comment: ] Frequency throttling, even on the most affected Skylakes, has always been a non-issue if you run say 1ms worth of continuous SIMD instructions. How could a 10-40% drop negate speedups from 2x vector width plus double the registers and a much more capable instruction set? It is time we buried this myth :)
