The James Webb Space Telescope is one of the most technically complex instruments humanity has ever built. It sits at the L2 Lagrange point, roughly 1.5 million kilometers from Earth, and peers into the universe in infrared light with a precision previously impossible. The onboard computer running all of this is a BAE Systems RAD750, a radiation-hardened processor based on the PowerPC 750 architecture. It has a maximum clock speed of 200 MHz. It is, for all practical purposes, a chip designed at the turn of the millennium.
