The only reason for a multicore benchmark is when the benchmark represents some common task that is not embarrassingly parallel. If your multicore benchmark is just a single threaded test run on a bunch of cores, it’s pointless. I can simply do math to find that result, max(single core performance multiplied by the number of cores, memory bandwidth divide by bandwidth required per thread). A good benchmark will be something people actually do. |
