Some reading here won’t know there already is an MCU3, sometimes referred to as MCUZ. The new cars all use AMD Ryzen chips. The instruction set didn’t change like from MCU1 (ARM) to MCU2 (x64) but the Ryzen’s embedded GPU has instructions that are certainly in use. Anyway, Tesla isn’t developing for future hardware as much as for a currently growing installed base of MCUZ.…and then we'll have an MCU3, MCU4, etc…as they develop more and more for future hardware…
It is a really big step to get the current, liquid cooled Ryzen in its different form factor into the legacy cars.…Do you really anticipate newer MCU retrofits for the legacy cars?
Also noteworthy is that the (self driving) HW3 is more physically integrated in MCUZ. So will Cybertruck and new roadster use the same CPU with HW4 and 4x resolution cameras in testing?
