(I later optimised the slower benchmark in that post: https://github.com/simdjson/simdjson/pull/1708 https://github.com/simdjson/simdjson/pull/1708 ) Obviously the GPU will be better, but at one point I compared the M1 CPU to other ARM GPUs (in laptops at that time) and found it had both better memory bandwidth and compute throughput, which is quite funny.
