Musk Clarifies Massive Terafab Site Needs Dwarf Giga Texas; Multiple Locations Evaluated

Post-announcement, Elon Musk distinguishes the small 'advanced technology fab' at Giga Texas from the enormous full Terafab, which requires thousands of acres and 10GW power, with sites under review.

Key facts

  • Terafab far larger than entire Giga Texas campus
  • Advanced fab for rapid chip iteration only
  • Requires unprecedented land and power infrastructure
No, that’s just the little advanced technology fab, where we will be iterating on chip designs. We couldn’t possibly fit the Terafab on the GigaTexas campus. It will be far bigger than everything else combined there. Several locations for Terafab are under consideration. It needs thousands of acres and over 10GW of power at full scale.
