remember that some changes are possible let's say up to 24 / 18 months from launch other are not, at least if you don't want to trash millions of dollars invested in in r&d and start over pushing away the launch. From the size of the console and the problems they are having to cool the removable SSD it does not seem that the cooling was all so calculated. The fact that the console performs well (or that the Xbox still underperforms hahaha) doesn't make me change my mind about how it is gone the design of the ps5 and you know how I think.That is core of architecture design. To me PS5 made clear deliberate bets on SoC size (for cost), portion of the die to dedicate to the custom SSD I/O (and minimise latency and remove memory bandwidth waste, see cache scrubbers), and GPU design to hit the high frequency needed to hit their performance targets (then they figured out how to cool it and how to keep frequency high on CPU and GPU). The advantage of this approach was that a lot of the GPU core shared by the CU arrays is now running a lot faster and the CU’s themselves can handle branchy code (dynamic if statements).
If anything, including the Zen FPU customisations as well as other customisations inside the GPU too (geometry engine customisations, smartshift, and Coherency Engines + cache scrubbers) speak of a very coherent architecture approach not a series of jumps reacting to “the enemy’s plans”.
