Apple will use its Custom A-series chip in its upcoming Macs and will remove AMD GPU support in future. This will be a bold move from Apple without a doubt.
Apple is focused on using its hardware in Macs and the transition from Intel to custom A-series chips was showcased in 2020s’ WWDC keynote. Hence, it’s much evident that Apple is all hands in to build and use custom hardware in its products.
Longhorn hinted on twitter that ARM-based Macs will be using GPUs made by Apple and the company is eyeing to build products that have specifications all tagged with Apple.
The first example of how capable Apple’s GPU can be is in a previous benchmark test, where the A12Z Bionic’s 8core GPU beat both the Core i7-1065G7 and Ryzen 5 4500U but only marginally.
Those low scores obtained by the A12Z Bionic were because of Apple’s translation layer Rosetta 2, as another benchmark report had revealed that only the performance cores were utilized and efficiency cores were left out. The A12Z Bionic isn’t going to be found in the future consumer-ready Macs. It only powers the Mac mini and meant for developers to test their apps.
We will see the first ARM-based consumer-ready Mac in late 2020. Reports claim that it will be powered by a custom 12-core SoC, with eight performance cores paired with the other four efficiency cores. The Unnamed 12-core custom A-series silicon might also support a more capable GPU than the upcoming iPhone 12’s A14 Bionic.
We are looking forward to see custom GPUs in action.
