" That GPU section is, not surprisingly, massive. The full chip is 360.4mm square, with 15.3 billion transistors. Doing some quick image analysis, the GPU takes up roughly half of the die (47.5% if you want a more precise estimate)."

"A Zen 2 CPU chiplet measures 74mm square (with four times the L3 cache compared to the Xbox Series X APU), and then tack on a GPU that has more features and shader cores than Navi 10 (RX 5700 XT), which measures 251mm square. That's 325mm square without the enhanced Navi 2x cores and 12 additional CUs."

Is it just me or do those sizes don't add up?

360mm², out of which the GPU takes less than 50%, so only ~175mm²? I find that die size hard to believe since Navi is already produced in 7nm, has less CU and no hardware Raytracing yet was already 251mm². If that is truly the size of the GPU part, then they would have needed to severely cut down on the cache sizes inside Navi to make it this small, I don't see what else they even could have cut.

CPU looks like cut out right of Renoir, complete with the cache size.
