Apple iMac with Retina 5K Display: There's action in the (high-end) desktop yet

In contempo years we've heard affluence about the acceleration of adaptable accretion application smartphones, phablets, tablets and amalgam tablet/laptops, with accompanying noises about how the desktop PC is 'dead'. The crammer desktop may accept had its day, but it seems that there's action larboard in aspirational/high-end systems, as exemplified by Apple's just-announced 27-inch iMac with Retina 5K Display. Added than an iPhone 6 or 6 Plus, an Apple Watch or an iPad Air 2, this is the new Apple artefact I'm agog to get my easily on.

Costing from £1,999 (inc. VAT; £1,665.83 ex. VAT), the new 5K iMac won't be for everyone, of course. However, it's abiding to be on the wish-lists of abounding a artistic able and flush consumer. So what's all the fuss about? Let's accept a look.

The accepted accepted for high-end displays is '4K' — so alleged because its 3,840-by-2,160 resolution delivers four times the cardinal of pixels as 1,920-by-1,080 HD (8,294,400 against 2,073,600). The new 27-inch iMac has a resolution of 5,120 by 2,880 pixels — "the world's highest-resolution display", according to Apple's chief VP of common business Philip Schiller at the barrage accident — for a absolute of 14,745,600 pixels.


This is absolutely 7.1 times the cardinal of HD pixels and 1.78 times the 4K pixel calculation (although, carefully speaking, 4K refers to the hardly college 19:10 4,096-by-2,160 video standard, while the 16:9 3,840-by-2,160 resolution is added accurately alleged UltraHD). Still, it's an absorbing resolution, whose 218ppi pixel body stands out amid the accepted crop of sub-200ppi all-in-one desktops and large-screen monitors. It's additionally alert the resolution, or four times the pixel count, of the absolute 109ppi 27-inch iMac.

The alone added '5K' affectation we're acquainted of is Dell's accessible UltraSharp 27 Ultra HD 5K, which is accepted to amount about $2,500 (~£1,500) — after a computer inside.

5K technology tweaks
Such an beforehand in resolution requires a cardinal of technology tweaks, which Philip Schiller categorical in Apple's 16 October presentation. These include: a distinct custom-design timing ambassador chip, or TCON, that orchestrates the action of anniversary of the 14.7 actor pixels; an oxide-based IPS TFT console that accuse quicker and holds allegation longer, carrying bigger brightness, accord and lower ability consumption; power-efficient LED backlighting; amoebic 'passivation' that separates pixels from the ascendancy signals to annihilate crosstalk in such a high-resolution panel; UV photo alignment for bigger accession of aqueous clear molecules, giving added adverse aback the adviser is beheld head-on; and a advantage blur to ensure bigger off-axis angel quality.

Computer attached

The iMac absorbed to this impressive-sounding affectation is based about a fourth-generation Intel Core i5 (3.5/3.9GHz) processor — or, for £200 more, a Core i7 (4.0/4.4GHz). There's 8GB of RAM as standard, but you can specify 16GB for £160 extra, or 32GB for £480 more. The abject amount includes a 1TB Fusion Drive or 256GB of PCI-e beam storage; £120 added gets you a 3TB Fusion Drive, while added PCI-e beam costs £240 for 512GB or £640 for 1TB. The absence GPU is an AMD Radeon R9 M290X with 2GB of committed GDDR5 video RAM; addition £200 upgrades this to a Radeon R9 M295X with 4GB of video memory.

For connectivity there's Gigabit Ethernet, dual-band 802.11ac wi-fi and Bluetooth 4.0, with ports and slots at the aback as follows: 3.5mm headphone jack; SDXC agenda slot; four USB 3.0 ports; two Thunderbolt 2 ports and an RJ-45 Ethernet port. If the 5K iMac's 14.7-million-pixel awning absolute acreage isn't abundant for you, it accompanying supports an alien adviser active at up to 3,840-by-2,160 pixels.


Although it's alone a few canicule back Apple appear the 5K iMac, the screwdriver-happy association at iFixit accept already appear a teardown analysis. Apart from the LG-manufactured 5K affectation console and the custom Parade Technologies DP665 LCD timing controller, iFixit begin a agnate set of apparatus and centralized blueprint to aftermost year's 27-inch iMac. The arrangement got an all-embracing repairability account of 5/10.

As mentioned earlier, this is exceptional accouterments that pushes the affectation resolution envelope and carries a amount tag to match. However, for some bodies — conspicuously video professionals who demand to appearance 4K video at built-in resolution and still accept on-screen amplitude for alteration controls — the massive pixel calculation makes sense. Aback we get a analysis sample, we'll let you apperceive whether we anticipate it's account the money.
