Britain just launched its top supercomputer. Here’s how it ranks globally
The UK has launched its most advanced supercomputer, Isambard-AI, which is the 11th most powerful in the world. The machine, built by Hewlett-Packard Enterprises (HPE) using its Cray EX architecture and fitted with over 5400 NVIDIA Grace Hopper superchips, has a raw computing power of 216.5 petaflops and a peak theoretical performance of 278.6 petaflops. This makes Isambard-AI more than 10 times faster than the UK's next-fastest supercomputer, the Njoerd supercluster in London. The launch of this powerful supercomputer reflects the UK's efforts to advance its technological capabilities and remain competitive in the global race for supercomputing dominance.
