I do think games have a lot more vary needs than most AI - which primarily need to crunch matrixes - so I'm a little sympathetic to a jump to many-chip failing. You also burn power on chip to chip interconnect, try as we might to ever optimize this down.

Well, the good news is RDNA4 is the last consumer chips. Good news because they are merging RDNA with CDNA (compute/ai) to make a new UDNA (unified), which all next next gen chips will be.
