However, it appears the electronics giant will go even further than this. A WWDC 2020 presentation slide that's circulating on Twitter suggests Apple will also dump AMD. At the moment, AMD is Apple's supplier of discrete graphics solutions but it seems this relationship is coming to an end.
The slide reveals the ARM-based Mac computers will exclusively support the unannounced Apple Metal GPU family:
The SoCs powering client-segment Macs, such as future iMacs or MacBooks, could feature iGPUs based on this graphics architecture, while larger platforms such as MacBook Pros, Mac Pros, and iMac Pros of the future could feature Apple's own discrete GPUs.
The future will be very interesting. macOS arm64 according to Apple removes support for AMD GPUs too, Apple GPUs all the way. pic.twitter.com/2hF8RwsO4C
