Unless you also predict that Apple will release datacenter systems a-la Grace and Instict, I don't think they're even in the runnings. AMD is only competitive in the LLM market because they sell extremely cheap and fast compute hardware at the same scale Nvidia does. As of today, Apple doesn't sell any hardware that can go toe-to-toe with a DGX system. They also have a lot of software problems (VM limitations, poor GPU API support, limited integration with open-source, etc.) that would need to be fixed for parity with Nvidia or AMD.

Apple will definitely push for on-device AI, but even in 2030 I firmly believe that they won't be leading the industry in performance. I'd be surprised if they even supported anything other than their proprietary CoreML by then.
