Remind me again why consoles are still a thing? They are literally rebadged AMD PCs. PlayStation 5 graphics card (GPU) is equivalent to the NVIDIA GeForce RTX 2070 and the Radeon RX 5700 XT.
As soon as Sony adopted the x86 platform, it was over. Mark Cerny did 15 presentations convincing Sony to use x86 for PS4. PS4 in particular is just BSD on AMD64, its fricking piss easy to write and optimize code for. PS4/PS5 are essentially x86 amd pcs running a OpenGL/Vulcan compatible GPU on top of a BSD based OS. couple that with numerous games using ue4x and its pretty easy and economical to put games on more machines.
