sony bad and all that but I enjoyed their ps5 teardown video.

their "no load times" marketing translated into actual engineering is soldering ssd chips to the board and using a custom controller chip to maximize read throughput.
also the cpu is x86-64, was kind of expecting ARM64.
@dthompson why arm? It would take a lot of effort to match the actual gaming performance of x86_64 with arm from what I know.
@dthompson if I remember correctly arm is a better low power solution. Battery powered devices can get a lot more time from an arm based processor. It's not as much of a concern for wall powered devices
