64CU? That would still be about 400m2 in Navi (RX5700 with 40CU comes to ~260mm2), and thus a pretty expensive chip to produce. I doubt it will get such a big chip and rather rely more on GPU clock, as that alone could make the console probably $50-100 more expensive than a chip with less than 300m2. |
Yep probably even higher, I always assumed Sony/Microsoft will use 7nm EUV because of my estimated die sizes, I ran the numbers for 64CU's:
251mm2 (Navi10) + 54.36mm2 (24CU) + 20mm2 (ray-tracing) + 40mm2 (cpu) + 32.64mm2 (2x 64-bit controllers) + 50mm2 (wasted die area) = 448mm2 on tsmc 7nm.
EUV reduces die area by 20% but I don't think it will have perfect scaling so I used 15% instead.
448mm2 * 0.85 = 380.8mm2 on tsmc 7nm EUV.
Ofc it could be smaller depending on how much wasted die area Microsoft can reduce, Xbox one X had about 50mm2 wasted die area and PS4 pro 70mm2 wasted die area, going from 16nm to 7nm might reduce wasted die area, I don't know.
What's interesting is that his TF number for Xbox series X is almost certainly a Devkit number and not retail version, the verified insider says PS5 has higher TF than Xbox series X but the retail version might be lower, all from 10.1-11.2TF as the memory bandwidth for PS5 just isn't there for 12TF.
