Samsung to build HW5 chip for Tesla

"The chips, to be manufactured on Samsung’s 4-nanometer node, will go into Tesla’s Hardware 5 (HW 5.0) computers, which the EV maker plans to mass-produce three to four years from now, industry officials said on Tuesday."

Out of curiosity what is the fab size of HW3 and HW4 chips? Usually automotive grade chips are made using standard designs in older fabs to save costs but since Tesla's are proprietary (also are they ARM architecture?) are they made on newer/smaller fabs like maybe 10nm/HW3 to 5nm/HW4?

According to this, HW4 is likely either a 4nm or 7nm TSMC process. HW3 used a 14nm process.

Well 1 to 2nm is got to be about the limit since your are getting into the limits of atoms. Remember clock speed used to be THE measurement thing for CPU's and that was supplanted by the number of cores and GPU's. So we will probably see some other shift since we are reaching the limit of size.

Yes, the old um days are long gone.

Think was a play to protect Tesla against the China invasion into Taiwan?

I remember sitting at lunch in the early 1980s, a new engineer amongst the seasoned veterans at the table. Some remark came up about vacuum tube circuits.

I mentioned that in my courses, I had only one lecture hour on vacuum tubes, and that an impromptu one, only at the request of the students.

An older engineer sitting across from me slumped down a little, and said that when he went to college he had only one lecture hour on transistors.

Next thing you know you are going to say Gen Z can't even tell time on an analog clock.

Let me fix that for you: ..., it reminds me how experienced I am.
