你這個問題在當初Tesla Autonomy Day 就已經回答過了
有與會者問了Tesla AI晶片設計負責人Pete Bannon 一個問題:
將目前Tesla AI晶片所使用的14 nm 技術降低到10 nm 或是更低會有意義嗎?
通過後面一系列的問答可以知道
Tesla 自製晶片的目標是在提升效能的同時也要降低製作成本
HW3.0 的成本比起HW2.5 的成本降低了20%,但是效能(TOPS)卻提升了6-7倍
對於車用晶片來說,散熱並不是很大的問題、空間更不是問題
要如何在效能與成本之間取捨才是問題
若用上更新的製程來設計、製造晶片,那研發與製造費用會大增
同時效能不見得會有相同幅度的提升
追求最新製程對Tesla 來說是沒有意義的

PS:
Pete Bannon 他是晶片大神Jim Keller 的長期工作夥伴,主要設計完成Jim
離開Tesla 後就將負責人職位交給他。
