Vectors, tensors, and matrices. Not all AI chips are GPUs though, there are currently NPUs in development and the next generation of consumer chips might have them integrated in the CPU.

They're not good for deterministic equations, like gravity, collisions, or pathfinding, but they could advance other aspects of games like procedural generations, fluid dynamics, NPC dynamic personalities and emergent behaviors.

Some things are still better left to the CPU or GPU, but offloading some tasks to the NPU might allow for more complexity like simulating full weather systems with Parametric Partial Differential Equations

I'm speculating, of course. But playing a game inside a fully-simulated physics engine seems like it could be cool (despite being resource-intensive in current hardware)
