en.wikipedia.org/wiki/Graphics_processing_unit

Sony coined the term GPU in 1994 for what was in the Playstation.

Nvidia might have marketed it as the first GPU, but other companies had combined 2D/3D processors on a single chip marketed to consumers well before the GeForce, including Nvidia themselves with the Riva 128. The GeForce was the first product from Nvidia marketed as a GPU, but that doesn’t mean it was the first product to market that was either called a GPU or not called that but still was one. It WAS the first to market with a T&L system (though Rendition had T&L on a chip first it never made it to market).
