HW3 Verification

SR+. So what does HW3 actually provide as opposed to 2.5? Can't find much info on it. . .

Isn't a lot known yet.

As far as we know right now, the only change is the computer module itself. HW3 is the custom FSD chip Tesla has been working towards for years, with Tesla designed neural network accelerators.

The board has two CPUs, each with two accelerators on it, for failsafe/redundancy. It is supposed to be a couple of orders of magnitude faster than HW2.5 at running NNs, and able to handle larger matrices as well.

Right now we have been told it is still running the same networks as HW2.5 cars for Autopilot - hence the similar performance. At some point it'll transition to the new FSD networks they've been developing in the background, which would mean an abrupt change in capabilities (hopefully for the better. :) )

I believe the only known difference in performance today is the identification method above - the new board includes hardware to encode video more efficiently in a format that didn't exist when HW2.5 was designed, so the TeslaCam videos take less space and (combined with the other board advantages) require a little less energy.
