Intel Prepares to Graft Google’s Bfloat16 onto Processors
> At this point, Intel doesn’t have bfloat16 implemented in any of its processors, so they used current AVX512 vector hardware present in its existing processor to emulate the format and the requisite operations.  According to the researchers, this resulted in “only a very slight performance tax.”Why implement bfloat if you get just slightly less performance emulating it with AVX512, which already exists? Maybe it’s an “us too” claim?
