It's much more effective at extremely high frequencies used in compact radars, like the kind used on fighter jets.

Yea fo sho', and it was the Cray 3 supercomputer actually based on gallium arsenide at the time, meaning faaasssttt clock rates, about 6x faster than compeititors in terms of Hz. So that would be something like a 50 ghz processor today, wild

There was a whole Byte magazine dedicated to it back in the day. It was thought (at the time) that the only way we'd ever break the 1 GHz barrier was to use GaAs, which obviously turned out to be wrong.
