The heir to the British throne Prince William, 43, has toured one of the world's most powerful computers.
He met Isambard-AI at the University of Bristol.
Isambard - named after the great 19th Century British engineer Isambard Kingdom Brunel - is capable of 21 quintillion operations per second. It can process data in one second that would take the global population 80 years to complete.
It is the 11th most powerful computer on Earth.
