252 Gops/s is a reasonable number as this is ~90% hardware efficiency. Currently FBGEMM and MKL-DNN can reach this number. For the current PR, the reason is that we didn't fully utilize the accumulation in `vpdpbusd` instruction, and we get 205.6 Gops/s (73% efficiency). -- You are receiving this because you are subscribed to this thread.
