Tesla is building its own AI chips for self-driving cars

“Nvidia’s hardware was handling about 200 frames per second, its specialized chip is able to do crunch out 2000 frames per second “with full redundancy and failover”.”

What are the real-world benefits going from 200 to 2000 frames a second? 200 seems quite fast.

Multiplexing different camera feeds perhaps? Could could do 200/fps split over 10 different camera feeds.

Nothing seems that fast at 50 m.p.h., however, excuse the mix in units, but each of those 200 frames is the equivalent of 10cm or so along the road. At 2000 frames per second then that is the equivalent of 1cm.

I don't make a habit of crashing cars but I did have one glancing head on crash, combined speeds around 125 m.p.h. and it was only centimetres that meant I did not wipe out that family and trash the car I was in.

As a consequence I would say that this 10x frame rate really is quite game changing, particularly for on-coming vehicles.

I think that comparison is just to illustrate the computational improvements. In other words, the new system is 10x faster. As Elon said on the call, that means they can now process all the cameras at full resolution and full framerate, which can improve accuracy and therefore ability and safety... which sounds like the real world benefits you're looking for.
