When will Apple release new iMac hardware in the UK? Will Apple update its iMac line to add Intel Kaby Lake processors, and what other tech specs and new features should we expect in the next generation of iMacs? How much will the new iMacs cost?
Apple last updated its iMacs on 13 October 2015, bringing the Retina screen to the smaller Macs for the first time and equipping the larger models with new Skylake processor chips. Before that, you had to go back more than two years - if you don't include the cheaper iMac which Apple introduced in June 2014 - to the last proper new iMac update, in September 2013, when Apple added Haswell processors, new graphics, next-gen Wi-Fi and faster PCIe flash storage options. (For more information on that update, read our review of the 2013 iMacs.)
So much for Apple's iMac updates over the past few years. We're looking ahead to the next iMac launch event - the 2016 iMac update, if we're right about timing. In this article we round up all the speculation about Apple's next iMac update: when new iMacs are likely to launch in the UK, prices, tech specs and new features to expect, any leaked photos and videos that appear online, and all the rumours that are fit to print.
Updated, 23 August 2016, to expand our thoughts on the new iMacs being VR-capable; on 9 August 2016, to consider the possibility that a pumped-up 'iMac Pro' could replace the Mac Pro; on 26 July, with the news that Intel has launched Kaby Lake processors, and on 12 July 2016 to discuss the inclusion of AMD CPUs in the 2016 iMac.

New iMac 2016 release date, price & specs rumours: Launch date
When will new iMacs come out?
The last iMac update, as previously mentioned, was in October 2015, and it would be a surprise if Apple returned to this product line less than 12 months later. Which appeared to rule out, despite the excitable hopes of some rumourmongers, WWDC 2016 - and indeed, Apple did not unveil the new iMac at its June event. (Although there was plenty of news about the forthcoming macOS Sierra operating system, and what that means for your current Mac, if it can run the OS. Read our guide to macOS Sierra's new features for more info.)
So October 2016 is the most likely date for a new iMac launch, then? Not so fast.
Apple's yearly cycle is built around three major press events: autumn - usually September (new iPhones and iPads); spring - usually March (new iPhones and iPads, sometimes MacBooks and watches); and summer - usually June (WWDC - operating system updates, and occasional hardware). But that doesn't mean the company stays quiet the rest of the year. Mac updates can be folded into the big three events, but they're often launched at their own smaller launch events. The iMac update in 2015 got its own announcement, a few weeks after the iPhone 6s reveal.
The iPhone 7 will most likely launch in September 2016, and it's possible that Apple will lump new iMacs in with that event. Whether it does this, or updates the iMac at its own event, or an event dedicated to new Mac hardware in general, will depend on how major the hardware update is going to be. A separate event would imply that Apple has something big up its sleeve.
But bear in mind that, unlike the yearly or event twice-yearly update events we're used to for iOS devices, desktop Mac refreshes have frequently come several years apart. WWDC 2017 (which will take place in June next year) is therefore a possibility, and we may have to wait even longer than that.
Still, we'll try to remain optimistic. Watch this space for clues and analyst predictions about the next iMac update as soon as they appear.
New iMac 2016 release date, price & specs rumours: Specs
We'll add leaked details about the tech specs of the new iMacs to this section as we hear them. Here's what we know so far.
We expect Apple to choose Intel-based CPUs, but there's a chance AMD could also make an appearance in certain iMac models. With the new AMD Zen processor, we hope to see the CPU make an appearance in a lot of high-end machines, given its tremendous processing power.
The new processor boasts 8 cores and 16 threads - a massive amount of raw processing power. Given the suggested price tag of the Zen CPU, we expect it either to be in the top-spec iMacs or be an upgrade option.
The inclusion of other AMD processors is also not far-fetched, as we still see it being an option for cheaper iMac models.
Apple skipped Intel's much-delayed Broadwell processors and went straight from Haswell to Skylake for the 2015 update. Skylake uses the same 14nm manufacturing process as Broadwell, but brings even greater CPU and GPU performance, along with reduced power consumption. But what chips will appear in the next set of iMacs?
Clearly that will depend on their launch date and the hardware that's available at the time. After Skylake, the next round of Intel processors, going into mass production in late 2016, will be Kaby Lake, followed in turn by Cannonlake (Cannonlake was due to be next, but it's been delayed until the second half of 2017). Then Ice Lake in 2018 and Tiger Lake in 2019, for those who enjoy this sort of thing.
Kaby Lake uses a 14nm process, same as Broadwell and Skylake, but Cannonlake switches over to a more accurate 10nm process.
If Apple does manage an iMac update before the end of 2016 the machines could feature Kaby Lake processors, but remember that Apple skipped Broadwell and delays are common in the chip sector - so we're not banking on anything.
Update, 26 July 2016: A development! Intel has started shipping its Kaby Lake processors, which offer support for Thunderbolt 3, USB 3.1 and DisplayPort 1.2. It's therefore now possible that Apple will squeeze Kaby Lake chips into the next iMac update, but by no means guaranteed, given Apple's past behaviour. Some of the Kaby Lake chips - including the ones that would fit the next MacBook Pro, incidentally - aren't expected to ship until very late 2016 or more likely early 2017, so be prepared for a wait. Read more on MacRumors.
It's believed that Apple's next generation of iMacs (or its higher-specced models, at least) will feature graphics chips from AMD's Polaris set, which were announced at the start of 2016.
WCCF Tech reports that AMD won the contract last October but was only able to get confirmation from additional sources in April 2016.
The contract is for two chipsets: Polaris 10 (previously known as Ellesmere) and Polaris 11 (previously known as Baffin), and WCCF Tech says these processors will appear in "new desktops and notebooks from Apple, which the company plans to bring to market later this year".
With the MacBook and MacBook Air having recently seen updates, and the Mac mini highly unlikely to incorporate a discrete graphics unit, the remaining candidates are the MacBook Pro, iMac and Mac Pro. MacRumors reasons that the power range of these chips makes Polaris 11 a strong fit for the MacBook Pro, while Polaris 10 suits the iMac.
The Polaris chips offer improved graphics performance compared with previous generations (as much as twice the speed per watt) and potential reductions in both power consumption and waste heat. They are built using a 16nm or 14nm FinFET production process, compared to 28nm on AMD's earlier chips, which means that the chip maker can fit more transistors in a given space (which makes the chips ideal for ultraportable laptops and ultraslim desktops - the latter fittting recent iMac designs) and, because the transistors are closer together, less power is needed to move a signal across them.
Apple's current iMac line-up features AMD Radeon graphics chipsets as standard in the 27-inch models. The 21-inch models come with integrated Intel Iris Pro 6200 graphics.
Talking about graphics architecture can be a little dry, but the Polaris rumour discussed above has a sexier element to it: VR.
AMD has consistently talked up its Polaris graphics chips as a way of bringing VR within the reach of a wider market of PC users. At present Macs are basically unusable for VR, as we discuss in our articles Can you use Oculus Rift with Mac? and How to use a Mac for VR, and Oculus founder Palmer Luckey specifically cited underpowered Mac GPUs as the reason why the company was focusing on Windows:
"People have said, 'Why don't you support Macs? So many people have Macs.' It's true. A lot of people have Apple hardware, especially in the laptop space. But the GPUs in those, they're not even close to what we're pushing for our recommended spec."
But adding Polaris GPUs to the iMac could change Luckey's mind. AMD's Roy Taylor thinks the company's new GPUs are about to massively expand the available market for VR. "AMD has just completed the shrink to 14nm [with Polaris]," he said. "This means we can produce GPUs that will run the minimum spec of VR at a lower cost, in larger volume, consuming less power and running faster. That means in the second half of this year and going forward, more people will be able to run those headsets."

VR remains a niche topic in tech - the number of people actually willing to shell out for the whole shebang remains small, even if casual gamers who try the Vive or the Oculus Rift tend to love it - but it gets a lot of press at the moment. And it can't be nice for a company that prides itself on the quality of its products to hear them disparaged as "not even close" to being up to a task.
As Jim Lynch on CIO colourfully phrases it, "As far as VR goes, it's not something that I have paid much attention to, but it certainly couldn't hurt for Apple's computers to be able to do it adequately... If VR lights a fire under Apple's rear end and gets the company to put out a pro version of the iMac, then it will be a good thing for all users."
New iMac 2016 specs: Flash storage
We'll repeat our hope, expressed this time last year while waiting for the 2015 update, that Apple makes flash storage standard across the entire range of iMacs. At present the 27-inch iMacs get a Fusion Drive by default (Fusion Drives are a high-performance hybrid blend of flash and conventional storage) and the 21.5-inch models can add them as a build-to-order option for an extra £80. We think it should be offered as standard in all Apple's desktops.
The current 21.5-inch iMac range is crippled somewhat by its hard drives, which are a lot slower than the flash drives used in all of Apple's laptops - to the extent that Mac laptops with similar processors will perform noticeably better than the equivalent iMac because of their faster SSD drives.

New iMac 2016 release date, price & specs rumours: Could the iMac replace the Mac Pro?
In our roundup of rumours about the next Mac Pro, we discuss the possibility that Apple is planning to wrap up that line - and one way such a move could work is by ramping up the top spec of the iMac line so that it meets the needs of professional users, rendering the Pro irrelevant.
TechRadar has speculated about the specs of a theoretical 'iMac Pro' - "that glitzy, 27-inch 5K display paired with a 10-core Intel Xeon E7 (or two) and the latest and greatest AMD FirePro W9100" - and in this day and age the number of Mac buyers who really need the top spec appears to be dwindling.
All of this is certainly a possibility. But while the Mac Pro doesn't appear to be tearing up trees commercially, it was never a line that was about making money. The Mac Pro is a flagship product, a niche offering and a positioning exercise - a way of reassuring Mac buyers that Apple is still a company that makes products for pro users. In some senses it's like the Apple Watch Edition: a glamorous, unnecessarily expensive aspiration point that passes on some of its stardust to the more affordable diffusion lines below.
