- Nvidia’s GH200 chips are the core of Britain’s Isambard-II Supercomputer
- It is the 11th fastest in the world and 10x faster than Britain’s second fastest
- The British Government hopes it will help with the discovery of drugs and more
Britain’s most powerful AI super computer, Isambard-II, is now fully operational in the Bristol Center for Supercomputing (BRICS), with some serious NVIDIA power at its core.
With 21 Exaflops of AI performance supported by 5,448 NVIDIA GH200 Grace jumps super chips, Isambard-IA now ranks 11 on the top 500 list of fastest supercomputers, making it one of the global leaders.
Nvidia stated that the British supercomputer is now 10x faster than the next British supercomputer and more powerful than all the others in the UK combined.
A giant leap forward
In addition to being the 11th fastest supercomputer globally, Isambard-IA also ranks fourth globally on the Green500 List of Energy Efficiency, demonstrating the progress made to reduce the environmental impact of AI machines and data centers.
Its eco-credit is endless, including carbon-free current, recycling of waste heat and a power consumption efficiency (PUE) of less than 1.1-among the best in the world.
Building in collaboration with NVIDIA, HPE and the University of Bristol, Isambard-IA received £ 225 million in government financing in the hope that the supercomputer would continue to help across important humanitarian issues such as drug discovery and climate modeling.
“And when we press this Switch to activate Britain’s most powerful supercomputer, we embark on the UK’s super future, with AI contributing to the delivery of better public services, greater public prosperity, deeper scientific discovery and stronger national security,” commented British State Secretary Peter Kyle.
Among its first projects are Nightingale AI, trained on NHS data in support of previous diagnoses and personal care, Britllm, designed to promote inclusive and better delivery of public service in the UK’s language, including Welsh; and UCL cancer screening AI for detection of prostate cancer.
