He's probably referring to the "overall performance", ie, raster may not be much better but it's RT performance is generationally superior than leaks suggest.
He's just using a semantic battle is my two cents. Which is wrong of course to speak and address in generalities when you full well know that's not what people are thinking.
I could be wrong but we'll see. If I'm not he's going to make AMD look even worse than they already do.
