I don't get why you are so upset about the CPU thing, what are you hinting at? that they are trying to run it at a speed where it doesn't use much power, or that they want to be sure that they will have higher yields on the CPU portion of the die? ... would you have prefered it if they went the Intel + Xe direction? Why not match such a CPU with a 4TF GPU assuming you lower your target resolution?
The point would be to have a lower cost version of the console that can still play 4K games in 1080p, for this to work you need the same (or a very close CPU), but you can sacrifice GPU power memory bandwidth, maybe have less RAM and storage on board, and remove a couple of non essential features from the system... Remember, this is an entry level system meant to play the same games at lower resolution.
I don't know if 4TF is the right number, but it would make sense to me, assuming the idea is to provide a lower cost entry.
