Apple October 2023 Hardware Event: MacBook Pro, iMac, M3, M3 Pro, M3 Max
Unlike its predecessors, which are built on 5-nanometer process technology, all three new chips are now built on a 3-nanometer process—this packs more transistors into a smaller space and enhances both the speed and power efficiency of the chip.Photograph: AppleThe M3 chips have a few features new to Apple silicon. The first, a feature Apple calls dynamic caching, enables the processor to allocate memory for each task dynamically, dialing the allocation up or down as needed rather than cordoning off a set amount of memory for the task to use whether it needs it or not. The result is a more efficient use of resources. The other new features—ray tracing and mesh shading—are put to use in graphics-intensive games and apps. Game developers can utilize ray tracing to more accurately illustrate...
