en.wikipedia.org/wiki/List_of_the_top_supercomputers_in_the_United_States

This page is specifically a list of top supercomputers in the United States, so including Cambridge-1 implies it is a U.S.-based system. NVIDIA's own current Cambridge-1 page calls it "one of the UK's most powerful supercomputers," and NVIDIA's launch article describes it as "UK-Based Cambridge-1" and "The U.K.'s most powerful supercomputer." Those primary sources contradict treating Cambridge-1 as a U.S. supercomputer.

The number in the article matches an older TOP500 result, not the current one. TOP500's current El Capitan system page shows 06/2026 values of 11,340,000 cores and 1,809.00 PFlop/s, with El Capitan ranked No. 2. The same official page also shows that 1,742.00 PFlop/s was El Capitan's older 06/2025 and 11/2024 figure. So the article is presenting a superseded performance value as current.
