Not that it isn't good for the M1 but is such a setup really something other companies are attempting to pull off? It seems like GPU makers just put more cores on a single die. Does this tech apply to discrete graphics? You can't really connect separate cards with this, right? Are you saying this is a blow to Intel's graphics? Or maybe you're implying it's a way for integrated graphics to become dominant?
