Britain’s most powerful supercomputer, the £225m Isambard-AI, has been officially launched in Bristol with promises that it could enable breakthroughs in areas such as medicine, robotics and climate change.

The supercomputer went from conception to deployment in just under two years and houses a colossal 21 exaflops of AI performance, powered by 5,448 NVIDIA GH200 Grace Hopper Superchips.

Isambard-AI is more than 10 times faster than the UK’s next fastest supercomputer and has more computing power than all other UK supercomputers combined. Scientists at Bristol University believe it could open the door to a range of applications, such as faster, more accurate cancer diagnoses and new clean energy innovations. It is already being used to analyse recordings from wearable cameras and other smart devices to help people perform tasks better at home – something that could assist dementia patients in the future.

Other examples include: using AI to analyse MRI scans, meaning cases of cancer can...
