The chip that Tesla revealed on Thursday is called “D1,” and it contains a 7 nm technology. Venkataramanan proudly held up the chip that he said has GPU-level compute with CPU connectivity and twice the I/O bandwidth of “the state of the art networking switch chips that are out there today and are supposed to be the gold standards.” He walked through the technicalities of the chip, explaining that Tesla wanted to own as much of its tech stack as possible to avoid any bottlenecks. Tesla introduced a next-gen computer chip last year, produced by Samsung, but it has not quite been able to escape the global chip shortage that has rocked the auto industry for months. To survive the shortage, Musk said during an earnings call this summer that the company had been forced to rewrite some vehicle software after having to substitute in alternate chips.

Aside from limited availability, the overall goal of taking the chip production in-house is to increase bandwidth and decrease latencies for better AI performance.</sup>
