What is established
Operational. 5 MW confirmed energized (gross site power); 5,448 accelerators (NVIDIA GH200); $288M announced investment; owned or developed by University of Bristol.
What is not disclosed
Timeline, named tenant, power source, cooling technology — not disclosed by any source on this page. Recorded as unknown, never as zero.
Analyst note
UK's most powerful supercomputer, fully launched July 2025, serving the UK AI Research Resource; 5,448 GH200 superchips. The 5 MW figure describes the operating facility, stated by the operator, hence recorded as confirmed. Capex converts the quoted £225M.
