“It isn't just about performance, either. AMD says that the chip will offer “leadership efficiency for exceptional battery life,” “
AMD could have left out “Leadership efficiency” to make the media release seem more impressive. Instead they went with a used car TV ad slogan. The industry accepts, because they pretty much have to, that X86 chips can ramp up power consumption to provide multi core performance above Apple Silicon M series — knowing what they can’t do is compete on efficiency. That’s accepted reality of the two different chip technologies. But obviously what they can do is say Hyper Optimum Efficiency! The Cutting Edge Of Green Performance! (in other words, empty slogans)
As far as single and multicore scores? It’s a big claim, let’s see it actually done.
