The BC250 does not use a PS5 APU, it uses another APU which has the same CPU core. By that measure the Cell in the PS3 and the Xenon of the XBox 360 were the same, or any AMD Jaguar device is a PS4.

This relates to the Intel problem because they see the world the way you just described, and completely failed to grasp the importance of SoC development where you are suddenly free to consider the world without the preexisting buses and peripherals of the PC universe and to imagine something better. CPU cores are a means to an end, and represent an ever shrinking part of modern systems.

There's almost no chance it isn't using rejected PS5 APU dies. It has fused off two of the eight CPU cores, as well as 12 of the 36 GPU compute units, but otherwise has the exact same specifications. The one customization Sony did get, the use of GDDR6 RAM, is still present. It also exhibits the same very short-lived mix of Zen 2 with RDNA 2 and has the same die size and aspect ratio.
