They didn’t call it a GPU then, but the SIMD architecture is quite similar at a high level.
Larrabee was going to be a GPU-like CPU. https://en.m.wikipedia.org/wiki/Larrabee_(microarchitecture)
Here’s a more modern GPU based computer: https://www.nvidia.com/en-us/self-driving-cars/drive-platfor...
If you meant something that sits on your desktop and runs Linux, then yeah it’s uncommon but not unheard of to run it on a SIMD system. The trend is absolutely definitely going toward SIMD being used in general purpose computing. Even if you don’t want to count any of my examples, you will see the “normal” PC become more GPU-like in the future than it is today.
