Based on the rumors that PS5 is using either a monolithic APU or dedicated chiplets, what if PS and AMD combined the APU and chiplet idea?

Instead of having one big APU or many smaller dedicated chiplets linked with infinity fabric, what if they had two smaller APU 'chiplets' linked?

Since we know it has Ryzen and Navi, each APU 'chiplet' could have 4 Ryzen CPU cores, and maybe 36 Navi GPU CU's let's say (the same amount as the PS4 Pro GPU). Take both APU 'chiplets' and link them together with infinity fabric, and use an I/O die if necessary. This way you would end up with 8 CPU cores and 72 GPU CU's, and could do so much more cheaply because your yields should be remarkably higher due to having much smaller chiplet APU's instead of one big monolithic APU.

Maybe this isn't technically possible or just wouldn't make sense, as a monolithic APU or dedicated chiplet design would be better overall possibly?

Yea, large monolithic chips hopefully can be replaced by clusters of chiplets in the future as that would mean much less wasted silicon waver area and should result in better prices. The problem is the bandwith of Infinity Fabric (IF), which afaik isn't quite high enough to seemlessly link several GPU chiplets into a big GPU. Even if AMD has a much more advanced IF rdy to go it could be prohibitively costly, as they don't seem to use it in their upcoming Navi GPUs (the one Lisa showed on stage at Computex was monlithic).
