The IBM PGC (1984) was a discrete GPU with 320kB of RAM and slightly over 64kB of ROM.
The EGA (1984) and VGA (1987) could conceivably be considered a GPU although not turning complete. EGA had 64, 128, 192, or 256K and VGA 256K.
The 8514/A (1987) was Turing complete although it had 512kB. The Image Adapter/A (1989) was far more powerful, pretty much the first modern GPU as we know them and came with 1MB expandable to 3MB.
- ErroneousBosh 11mo agoNeither 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.
