VERY unlikely you'll see an open GPU - they're all too worried about lawsuits because so much of their architectures are the same.

Sparc is also open and has been for quite some time.

That in of itself isn't true.

If you make GPUs like NVidia, AMD, and Intel do, you may be sued.

However, nothing stops you from just spamming extremely simple cores attached to a standardized bus architecture that talks to a singular extremely wide and fast memory controller.

Largely, this is slowly what GPUs are turning into.

Yeah, that's a lot like what I'm thinking, or at least, they're going in the right direction.
