For a while, it looked like AMD was pursuing the same route they did with their CPUs on their GPUs, developing small-scale GPU dies and connect them through some variation of the Infinity Fabric they use for their processors. And I think it would have been a great idea, using smaller and cheaper chips to create bigger and more powerful GPUs that are able to compete with Nvidia's offerings (remember the "2x480 offer the same performance as a 1080" bluff we got when AMD launched Polaris?), but it looks like they underestimated the difficulties, or the results weren't as good as they hoped for.

In any case, going for smaller dies isn't going to work now unless they have the performance to challenge/match Nvidia's products, and given that they can't do it now with big dies, I don't see how they'll be able to do it with small ones (unless they can use magic, of course).

Well. It might be possible now as nVidia has pulled a Geforce FX with the 2000 series, that has given AMD some breathing room to catch up possibly.
Th RX 480/580 was still a large chip for the performance level we got though... And Vega 64 was massive.

Vega 64 for example was 486 mm².
The Geforce 1080 was 314mm2.
***************************
Radeon RX 480 was 232mm2.
Geforce 1060 was 200mm2.

AMD has a big issue in regards to efficiency and die size, they need to rein it all in, because not only were the nVidia chips smaller, they used less power and they were faster.

Well, now that AMD has a proper CPU I'm sure they could scale back the compute side of their GPUs, freeing space to make them smaller or better at games. But that would probably affect their DX12 performance and, with Ray Tracing gaining traction, that side of their GPUs could come in handy for that.

So, what AMD/RTG needs is to drop GCN and develop a new architecture from scratch (or almost). Too bad that's easier said than done.
