Neither EGA or VGA were "GPUs", they were dumb framebuffers. Later VGA chipsets had rudimentary acceleration, basically just blitters - but that was a help.

The PGC was kind of a GPU if you squint a bit. It didn't work the way a modern GPU does where you've got masses of individual compute cores working on the same problem, but it did have a processor roughly as fast as the host processor that you could offload simple drawing tasks to. It couldn't do 3D stuff like what we'd call a GPU today does, but it could do things like solid fills and lines.

In today's money the PGC cost about the same as an RTX PRO 6000, so no-one really had them.
