Key facts
- Elon Musk wants to pack 660,000 NVIDIA GB300 GPUs into his Colossus 2 AI training cluster by late December
- The broader Memphis complex, which encompasses Colossus 1, Colossus 2, and future buildings internally referred to as “Minihard,” aims to eventually exceed 1 million total GPUs with an aggregate
- The longer-term answer is a 1.2 GW permanent power plant in Southaven, Mississippi, expected to reach full operational capacity by mid-2027
- Each Blackwell GPU delivers substantially more floating-point operations per watt, which is why 612,000 B300 GPUs can deliver the equivalent of 1.8 million H100s worth of compute
Summary
The xAI supercomputer in Memphis is already the world's largest AI data center by power consumption, and it's about to nearly double its GPU count. Elon Musk wants to pack 660,000 NVIDIA GB300 GPUs into his Colossus 2 AI training cluster by late December. The planned expansion would bring the Memphis complex’s total GPU count well past the half-million mark for Blackwell-series chips alone. Powering all of this requires 946 megawatts of IT power. XAI, operating under the designation SpaceXAI for this project, isn’t keeping the facility to itself either.
