@rygorous So if you have 10 adds and 10 muls, you could do them simultaneously, right, because they issue to different units. -
@rygorous So the throughput doesn't "take that into account", in that sense... you're just saying that _for the mul_ itself? - Show replies

@cmuratori That's the problem I'm alluding too - the figures are all over the place in every reference, sadly. :/ -
@cmuratori For example, the "0.33" rcp througput for PANDs in the Intel reference is not "takes 1/3 of a cycle", it's "can issue 3/cycle". - Show replies
