The new processors are from Intel's Kaby Lake family, and some of them have been available for the better part of a year.
Apple has also updated the 13-inch MacBook Air with a 1.8 GHz processor. In other words, Apple managed to pack in a larger display in what is only marginally bigger than the 9.7-inch Pro model. The MacBook Pro 13-inch laptop with a Touch Bar will start at £1,750, while the 15-inch version will start at £2,350.
Elsewhere, the improvements to the display are said to make it 43 per cent brighter with "support for 1 billion colours".
Apple predicts 30 percent faster CPU performance than the A9X chip in the first-generation iPad Pro models, and 40 percent faster graphics performance. The Fusion Drive will now be standard on all 27 inch configurations as well as the high-end 21.5 inch iMac. The device may help Apple rekindle its relationship with professional-level users dismayed by the relative lack of updates to its Mac Pro, which hasn't seen a notable upgrade since 2013. Featuring a new, next-generation compute core and up to 16GB of on-package high-bandwidth memory (HBM2), iMac Pro with the Vega GPU delivers up to an awesome 11 Teraflops of single-precision compute power for real-time 3D rendering and immersive, high frame rate VR.
Apple has also updated the iMac to faster Kaby Lake processors up to 4.2Ghz with support for up to twice the memory as the previous generation.
The tech giant said that its iMac Pro will start at $5,000 and that it would start shipping in December. At 600 nits, the new display actually outshines the new iMac screens, allowing iPad owners to watch HDR video on their devices for the very first time. The 21.5-inch iMac will have up to 32GB in memory, and the 27-inch will go up to 64GB. Like the Amazon Echo and Google Home, Apple's HomePod speaker will play music while also helping people to manage their lives and homes. This comes from bringing the Apple File System to Macs, after adding the technology to iOS in March.
It will also be taking advantage of AMD's Radeon Vega graphics and will feature up to 16GB of VRAM. The company had Industrial Light and Magic's John Knoll on stage for a live demo of a Vive virtual reality Star Wars game using a Mac.
