4K/5K iMac

With bet­ter screens, pow­er­ful pro­ces­sors and graph­ics, and USB-C, there’s a lot to be ex­cited about, re­veals Michael Si­mon

We might not have had a look at the cus­tom­iz­a­ble Mac Pro that Ap­ple is work­ing on, but that doesn’t mean Tim Cook and friends didn’t de­liver some se­ri­ous up­grades to our desks dur­ing Ap­ple’s WWDC. And with the lat­est up­dates just un­veiled for the iMac, there just might be a model to sat­isfy ev­ery­one.

While the new iMacs might look the same on the out­side, they’re quite a bit dif­fer­ent in­side. It

starts, of course, with the screen. Ap­ple says the new mod­els have the “best Mac dis­plays ever”, up­ping the bright­ness to 500 nits to make them 43 per­cent brighter while bring­ing sup­port for a bil­lion colours.

You’ll also get faster In­tel Kaby Lake pro­ces­sors up to 4.2GHz, higher mem­ory ca­pac­ity, su­per-fast stor­age, and next-gen­er­a­tion graph­ics, as well as a pair of Thun­der­bolt 3/USB-C ports (which aren’t even avail­able on the Mac Pro yet).

The en­try-level 21.5in model fea­tures an In­tel Iris Plus 640 GPU while the 4K model now sup­ports dis­crete AMD Radeon Pro 550 graph­ics with up to 4GB of VRAM. It also comes with 32GB of RAM and an SSD drive that is up to 50 per­cent faster. The step-up 21.5in model, mean­while, will fea­ture Radeon Pro 555 or 560 graph­ics and standard fu­sion drives.

The 27in 5K model of­fers up to 64GB of RAM, standard fu­sion drives, and a choice be­tween the Radeon Pro 570, 565, or 580 cards with up to 8GB of VRAM for 5.5 ter­aflops of graph­ics power. And cou­pled with the new im­prove­ments in macOS High Sierra, th­ese new ma­chines will be at the fore­front of VR con­tent cre­ation.

Ad­di­tion­ally, the new ma­chines bring a host of mi­nor im­prove­ments, in­clud­ing an im­proved 1080 Face­Time cam­era, UHS-II SDXC card slot, and Blue­tooth 4.2.

The 21.5in model starts at £1,049, while the 4K ver­sion starts at £1,249. Ad­di­tion­ally, the 27in model will cost you £1,749 for the base model while the top-ofthe range op­tion will set you back a whop­ping £2,249. The new iMacs are avail­able to buy now.
