The claim
Tesla's refreshed accelerator roadmap renames AI chips to SI (Super Intelligence); SI6 aims for about 80x HW4/SI4 compute and 9x memory around 2029-2030, while Dojo D3 becomes a chiplet design with stacked HBM aimed at scalable and space-ready training.
Why we rated it Likely
Tom's Hardware reported the roadmap from a Tesla presentation dated around Nov 4-6, 2026, including a table that maps SI4 (current car inference), SI5/SI6 and Dojo D3. The SI branding matches Musk's recent 'Super Intelligence' language, and HW4/AI4 already shipped, so the rename of current silicon is straightforward. Absolute TOPS numbers are estimates derived from Musk's old HW3/HW4 multipliers, and D3's schedule, process and performance are still blank on the slide, so this is Likely rather than Confirmed company product timing.
