To me whats going on seems clear enough, Intel has been chosen as a military- strategic company (always has been, but I mean further into this, like defense companies) while Nvidia is both, strategic and consumer. Hence this fusion is a matter streamlining purpose for Intel, probably processors , memory, fabs, and gods knows stuff we will never see now.
AMD has been left alone in the consumer market, and as maybe backup roles.
It wouldnt surprise me if Intel got bigger, but more silent, while AMD stays more flashy in the the consumer market.
