The only reason it’s harder for the computers on the roads is because there are a lot more stupid humans in close proximity than there would be in open air. Under a well designed fully autonomous system cars wouldn’t need 95% of the things we humans need to drive effectively.
I got a 13900k for $425 so I’m back on Intel, but if AMD could offer their 7800x3d at sub $300 I definitely wouldn’t have sprung for that deal. Buying under half the multithreaded performance for a mere $60 in savings didn’t really appeal to me (especially since I run an Unraid server and put parts from my gaming desktop in there once I upgrade).
