As of 2024, the most powerful AI computer is the Isambard-AI supercomputer in the UK. It boasts over 200 petaflops of computing performance, meaning it can perform 200 quadrillion calculations per second. To put this in perspective, Isambard-AI can handle tasks that would take traditional PCs years to complete in just seconds. For example, it can simulate climate models, accelerate drug discovery, and analyze astronomical data.
