A building with machines, power and cooling whose output is compute. It gets financed like a power plant, not like software.
Update, 16 August 2026: the wires are part of the factory too. On 11 August NVIDIA explained the 800 VDC architecture - high-voltage direct current so there are fewer conversions between the grid and the chip and more of the power reaches the compute. NVIDIA, Google and Microsoft develop it through the Open Compute Project; according to NVIDIA more than 80 manufacturers are already building equipment to the specification. A hybrid 800 VDC rack for existing buildings arrives in the second half of 2026, a row-level power centre up to 2 megawatts - in 2027. Models change in months; a building's electrical installation - once.
