If you really want to analyze die space usage ou have to do a lot better than that. Take the XB1Xfor instance, it has 12GB of GDDR5 RAM.. its memory controllers fit into a chip thats about 350mm2 along with a CPu and 40CU GPU. Going from 12GB of GDDR5 to 24GB of GDDR6 (just an example) will take the same amount of space with regards to on chip memory controllers. Its been calculated that the Ryzen CPU will take about the sameamount of space on a die that jaguar takes right now. That leaves a gd dalaount of space for the GPU.

Ryzen 3 is about 80mm2 for an 8-core complex at 7nm.
Jaguar is 24.8mm2 for an 8-core complex at 28nm.
That doesn't include things like I/O.
At the end of the day, CPU cores themselves tend to be relatively small anyway, it's everything tacked on to hide bandwidth and latency (I.E. Caches) that drives die sizes of CPU's up.

Its not really an apples to apples comparison though.... cause I/O in a dedicated CPu and I/O in an APu are kinda two very difeent things.
How about this...
AMD Ryzen 3 3600G (7nm)
- 8C/16T
- CPU clock 3.2GHz base/ 4Ghz Boost
- Navi 20CU GPU
- TDP 95W
- MSRP (rumored) ~$225
AMD Ryzen 3 3600 (7nm)
- 8C/16T
- CPU clock 3.2Ghz base/ 4.4Ghz boost
- TDP 65W
- MSRP ~$200
I think that is where we need to start looking at things from. This is the closest thing to an apples to apples comparison we will see. Here are my takeaways.
- TDP for a spec of the chip (at least the CPU) is only 95W for CPU and a 20CU GPU. But thats to accomodate a CPU that is designed to clock as high as 4Ghz.
- Addition of a 20CU Navi GPU (of unknown clock for now) raises TDP of the package by 30W.
When that chip is released later this year, we can then look atthe size of the chip and see where it falls in the whole 200mm2 to 400mm2 range.
