The first element… doesn’t require much insight: an A14X chip to power both the next iPad Pro and also a MacBook. It has previously been speculated that this would be a new 12-inch MacBook, the more power-efficient chip providing a 15-20 hour battery life.
It says this would be followed by an A14T variant, which would be used in an Apple Silicon iMac. It also suggests that the iMac would get a new Apple GPU, code-named Lifuka…
Apple has historically offered integrated GPUs in lower-end Macs, and discrete GPUs in more powerful models. There has been a suggestion that this approach will continue with Apple Silicon Macs, and that Apple might be able to provide impressive graphics performance from integrated GPUs. Apple wrote, “Don’t assume a discrete GPU means better performance,” in its developer support document.
MacDailyNews Take: So, three A14 chip variants: A14 for iPhones, A14X for iPads and consumer MacBooks, and A14T (Terrific? Tremendous?) for higher-end and Pro Macs. Next year, it’ll be the A15, A15X, and A15T and so on.
