iMac also comes with the best Mac display ever, now 43% brighter at 500 nits and with support for 1 billion colors, delivering an even more vivid and true-to-life viewing experience.
The new graphics processors are now powering the 15-inch MacBook Pro notebook and 21.5 and 27 inch iMac all-in-one systems.
And productivity looks to be high on Apple's agenda with the iPad Pro given it took time to show-off new spit-screen multitasking capabilities, drag-and-drop functionality, and an apps dock that resembles the macOS version, for iOS 11 on the iPad.
There's a vent in the back, and two new Thunderbolt 3/USB-C ports, which, compared to Thunderbolt 2, offer twice as fast data transfer and display bandwidth. The 27-inch models now offer Turbo Boost (which kicks your computer into overdrive when you're running especially processor-intensive applications) up to 4.5GHz, while the 21.5-inch Retina 4k model goes up to 4.2 GHz. These are said to be 3x faster than the previous gen graphics unit. Users can also opt for a more traditional 128GB of ECC memory model.
Now for the pricing, the MacBook costs $1299 for the base model while the MacBook Pro with function keys will start at the same $1299. With this launch, Apple is also updating the base storage for the iPad Pro to 64GB. At yesterday's Worldwide Developer's Conference the Cupertino giant unveiled a host of new upgrades and hardware to its computing lineup which includes the most powerful Mac ever. The 15-inch MacBook Pro now comes standard with more powerful discrete graphics with more video memory, and the 13-inch MacBook Pro adds a new £1,249 configuration.
The iMac Retina 5K 27-inch will have a Radeon Pro 570, 575, or 580 and up to 8GB VRAM.
Apple upgraded all the MacBook Pros it had introduced in 2016, and the 2017 versions come with Intel's 7th generation Kaby Lake processors. The processor is Intel core i5 dual-core, and clock speed of 3.1GHz, with up to 3.5Ghz Turbo Boost. Apple gives a sneak peak of iMac Pro features and it's just breathtaking.
I wouldn't recommend it if you don't truly have a specialized need-it's a very expensive machine-but enthusiasts who have held off and professional content creators will get a lot more power from the new 5K iMac.
