hmm i think i read @dweiss results in the wrong order... it seems like a fairly big difference? we actually regress scalar dotproduct for his cpu here. And I assume the vector case behaves the same way? if we want to avoid it on zen2 I am fine with it, if you tell me how to detect it. But i assume on zen3 things are fine, fma has lower latency. -- This is an automated message from the Apache Git Service.
