It's not about the chip per se. In order to build a scalable super computer there are a lot of stuff you need to build (operating system, scheduler, networking, et c et c.). Then you need to port pytorch and everything else and optimize it. It was hubris to try to build it all in house.

Elon: FSD Beta tweets
- Thread starter Terminator857
- Start date
It is usual Elon bollocks, overpromise and under-deliver stuff.
Tesla is quiet about D2 chip specifics or integrating into Dojo. Elon said the hardest part was getting the cluster to work. There were probably more than a few issues. Some high performance computer folks say the D2 is a lab queen beast and a daunting task to attempt. Tesla will likely never recover all that time and money lost.
And then there's the D1 Dojo cluster of ~3000 chips in 2021. More recently Tesla opted for ~10,000 NVDA H100 GPUs around the time the D2 cookie crumbled. I'm not sure Tesla can officially call NVDA clusters Dojo. If so dojo might be DOA-jo.

S and X to get front bumper cameras in March. How long before 3 and Y also get them?

Bizarre this would be in the plans fleet-wide but not have been done during the Highland refresh of 3
The early pics showed it so it is likely all the wiring and mounting are in place. I suspect Tesla removed it before release because they didn't want to deprecate the Y any more than they already were. Which means there may be an upgrade path for Highland buyers.

I know on HW4 Model Ys at least it's neither wired, nor is it even populated on the HW4 computer--- is there any evidence production Model 3s got HW4 with wiring or a populated connector on the computer?
Since there is no tear down yet we can only speculate but the early test cars had it and Tesla even accidentally showed a Model 3 with it on the Chinese Tesla website. Here is a Tesla website screen grab.

Theory: waiting on part(s), such as camera to be in sufficient supply.

Then why would they have made HW4 boards without the connections to attach it if they planned to attach them later?
They obviously make HW4 boards WITH the connectors since they are in the Cybertruck.

Right.
Why make two different boards if they planned to retrofit 3/Y later.
Tesla HATES making multiple configs of parts.
It's "the same board" just not populated completely because they don't plan on retrofitting those cars.

No, it's not the same board that they just didn't solder a connector. Green specifically called that out in the quote I provided, see the part in parenthesis.

A reply from Elon to James Douma. Elon says training compute is still the limiting factor:
Nothing happens fast for FSD nor does it follow the 'you can get it fast or good' golden rule.
