The Nvidia NV1 was released in 1995, it was the first GPU with 3D capabilities for PC… form there we know how things went by.
Now it’s 2023, so let’s make some “retro futuristic” prediction… what would you think about a AI board, open source driver, open API as Vulkan which you can buy to power the AI for your videogames? It would make sense to you? Which price range it should be?
What’s supposed to do for your games… well, that’s depend on videogames. The quickiest example I can think of is having endless discussion with your NPC in your average, single player, Fantasy RPG.
For example, the videogame load your 4~5 companions with the psychology/behaviors: they are fixated with the main quest goal (like you talk with fanatic people, this to make sure the game the main quest is as much stable as possible) but you can “break them” by making attempt to reveal some truths (for example, breaking the fourth wall), and if you go for this path, the game warns that you’re probably going to lock out the main quest (like in Morrowind when you kill essential NPC)
If this were to ever become mainstream this would likely be incorporated into the GPU for cost reasons. Small machine learning acceleration boards already exist but their uses are limited because of limited memory. Google has larger ones available but they’re cloud only.
Currently I don’t see many uses in gaming other than upscaling.
