Tesla updates its AI accelerator roadmap: The SI6 chip delivers 80 times the computing power of HW4, and Dojo D3 is now being designed for space deployment.

Tesla has announced an updated AI accelerator roadmap. The sixth-generation inference chip, the SI6, is expected to deliver 80 times the computing power of the fourth-generation HW4 chip and will be manufactured by Samsung using a 2nm process. Tesla has also restarted development on the Dojo D3 training chip, shifting from its original wafer-scale architecture to a multi-chiplet design with stacked HBM, while renaming its AI product line to the SI series.
