Apple Updates The iMac Line With a 21.5" Retina Modelby Brandon Chester on October 13, 2015 10:55 AM EST
Almost exactly one year ago Apple launched their first ever iMac with Retina display at their October 2014 event. The launch had a number of surprises, with one of the biggest being the fact that it would sell for $2499 despite its 5K display matching the resolution of Dell's UP2715K which had an intended launch price of $2999. While Apple doesn't appear to be planning any more events for this year, they have decided to ship an upgrade to their existing 27" iMac with 5K Retina display, and have also introduced a brand new 21.5" iMac with Retina 4K Display. You can view the specs for the base models of Apple's new 2015 iMacs in the chart below.
|Apple iMac With Retina Display 2015|
|Model||21.5" Base||27" Base|
|CPU||3.3GHz Core i5-5675C/R
|3.5GHz Core i5-6500
|GPU||Intel Iris Pro 6200||AMD Radeon R9 M380 (2GB)|
|Display||21.5" 4096 x 2304 IPS LCD||27" 5120 x 2880 IPS LCD|
|Memory||8GB 1867MHz DDR3 (LPDDR3 in 21.5")|
|Storage||1TB 5400RPM HDD||1TB 7200RPM HDD|
Just briefly touching on the 27" iMac, it's mainly an upgrade to the internal hardware from its original Intel Haswell platform. The CPU in the base model is now a 3.5GHz quad core i5-6500 which is an Intel Skylake part, and the upgraded options include a 3.3GHz i5-6600 and what is seemingly the 4.0GHz i7-6700K which would typically be an unlocked part, although I wouldn't expect any overclocking to be accessible. The GPU is now AMD's R9 M380. The GPUs also move to AMDs M300 series, with an M380 in the base model, an M390 in the mid tier, and an M390X in the high end model, all with 2GB of GDDR5 memory. There's also the M395X with 4GB of GDDR5 memory available as a BTO option.
The 21.5" iMac is the most interesting of the two new devices purely due to it being a brand new machine. Apple calls it the iMac with 4K Retina display, and it means that there are now Retina display options for both display sizes of the iMac. Speaking of the display, it's a 21.5" 4096 x 2304 IPS panel, which is higher than the 3840 x 2160 UHD resolution shipping on most "4K" displays, and it has enough horizontal and vertical resolution to natively display actual DCI 4K content.
In addition to the 21.5" model's new HiDPI display, both models of the iMac receive a boost to their color gamuts. Apple is now claiming support for the DCI-P3 gamut which is used in digital projection movie theaters, and this has been achieved by moving from a WLED backlight array to something similar to GB-r LEDs in order to increase the range of spectral emissions. What will be interesting to see is if Apple allows users to revert to the sRGB color space, which would require the inclusion of a 3D LUT that could also be used for more accurate self-calibration than the past.
I do question the choice of DCI-P3 over Adobe RGB though. Apple claims that most cameras can capture a wider color range than sRGB, which is true, but in my experience they'll usually only offer Adobe RGB as the other option. The DCI-P3 gamut is more similar to Adobe RGB than sRGB is, but it's definitely not the same and so there will be some error there when working in Adobe RGB without the correct gamut on the display. That being said, the fact that both displays can natively display DCI 4K content means they could theoretically be used for video editing, but I question the viability of mastering films for cinema projection with the processing power available in an iMac.
Beyond the display, the 21.5" iMac with 4K Retina display seems to stick with Intel's Broadwell platform rather than Skylake, as Apple needs to ship a part with Iris Pro graphics in order to drive the display. The CPU used is the 3.3GHz i5-5675C/R, with it being unclear whether it's the C or the R SKU which would mean a socketed or a BGA CPU respectively. I doubt many people would be adventurous enough to open up the chassis and replace the CPU even if it was possible anyway.
Apple has also brought down the cost of the Fusion Drive upgrade, but it comes with a sacrifice. The 1TB Fusion Drive now only has a 24GB flash memory segment, while it was previously 128GB. Both the 2TB and 3TB Fusion Drive options still come with 128GB of flash storage. While the 1TB Fusion Drive may still be worth it on the 21.5" iMac purely due to how slow 5400RPM HDDs are, it's hard to stomach paying $100 for 24GB of NAND, and I would definitely just stick with the standard HDD if I were buying the base model 27" iMac.
Both new Retina iMacs are available for purchase on the Apple Online Store, with shipping times as early as one business day. BTO configurations will obviously take longer depending on which customizations are chosen. The 21.5" iMac with 4K Retina display starts at $1499. The 27" iMac with 5K Retina Display starts at $1799, with the 3.2GHz R9 390M + 1TB Fusion Drive model at $1999 and the high end 3.3GHz i5, R9 M395 + 2TB Fusion Drive model at $2299.

blackcrayon - Tuesday, October 13, 2015 - linkI wouldn't buy that low end iMac (not cost effective vs moving up to the 27") - but they've gotten rich mostly from iOS devices, which are always reviewed at or near the top in most categories (as are Macs as well overall)...
Shiitaki - Tuesday, October 20, 2015 - linkWithout the progression of hard drives in the Mac line up. there would not seem to be reason to buy anything but the bottom model for most buyers. And that means selling fewer high end models than they do now. And interestingly, this approach leads to happier customers. Because those other parts like graphics or bigger screens are things that are hard to sell initially, impossible to install afterward, but often make people happier in the long run with their computer.
The experts are the ones that go online and order BTO.
repoman27 - Tuesday, October 13, 2015 - linkBroadwell in the 21-inch. OK, kinda expected that. Skylake in the 27-inch, but still no Thunderbolt 3 or USB Type-C. And after AMD rolled out the R9 Nano, I was really hoping Apple would offer a 27-inch with Fiji. Stupid Apple.
lilo777 - Tuesday, October 13, 2015 - linkIt is very common for Apple to use outdated components to save costs. Nothing new here. Outdated hardware at high price.
repoman27 - Tuesday, October 13, 2015 - linkApple never uses outdated components to save costs. Their choice of components is dictated almost entirely by either engineering or supply chain decisions. The lack of 4+4e CPUs, Alpine Ridge and Fiji in this round of iMacs strongly suggest that Intel and AMD don't have sufficient yields to supply Apple with those parts.
osxandwindows - Wednesday, October 14, 2015 - linkSo intel 6400k is outdated

That only makes sense if you intend to upgrade the HD yourself. Despite the price, non-hybrid drives cause WAY too much pain for everyday use. It's absolutely not worth it to forego even the 24GB Fusion, even for $100. Just upgrade to 2TB if you're that concerned about value.

I'm sorry but this is an utterly idiotic comment that shows an utterly idiotic view of looking at the world. You have two choices:
$1500 for a Mac with a slow hard drive or
$1600 for a Mac with a fast hard drive.
And you think the $1500 is the sensible choice???
It is IRRELEVANT what the cost of flash is. The point is the value to you that is delivered by the product. If you don't think a "fast hard drive" is worth $100 more than a "slow hard drive" might I suggest that you haven't actually used a pure hard drive in a while.
You can, of course create your own Frankensystem. You can buy an external USB-3 SSD and boot the OS off that. (I am doing that right now with my 3yr old iMac whose internal HD has started failing). You can even set up a fusion drive between a small external USB SSD and the internal HD (I have that booting my 2007 iMac).
But these are not the setups most people want when they initially buy the system; they're the setups people drift into when the system has become old and you're trying to keep it alive for a few more years to extract maximal value.
