Apple iMac overview

  • 1Description

Apple weds high-res 4K visuals into its sleek 5mm thin 21.5" iMac with Retina 4K Display. With a 4096 x 2304 native resolution, this iMac provides 9.4 million pixels, which is 4.5 times more than the Full HD 1080p 21.5" iMac. The Retina 4K display also features a wider color gamut. Using a P3-based color gamut, the Retina 4K display provides a 25% larger color space than standard sRGB displays. And with more available colors, the images will appear more vivid and reveal greater detail.

The iMac houses a quad-core 5th-gen Broadwell 3.3 GHz Intel Core i7 processor with 16GB of 1867 MHz LPDDR3 onboard RAM and integrated Intel HD Graphics 6200. For storage, the iMac has a 2TB Fusion Drive.

Outfitted with 802.11ac Wi-Fi (backwards compatible with 802.11a/b/g/n) for the speediest hook-ups to your home network, this iMac is also configured with Bluetooth 4.0, as well as an SDXC card slot for extra storage, four USB 3.0 ports, two Thunderbolt 2 ports, and a Gigabit Ethernet (RJ-45) jack. It also has a Kensington lock slot for added security.

For ports, the iMac has dual Thunderbolt 2 ports (which also double as Mini DisplayPorts) and four USB 3.0 ports. You'll be able to connect with various compatible components. If you would rather go wireless with your peripherals, you can use Bluetooth 4.0 technology where compatible.

Retina 4K Display
Whether your iMac is in your studio, living room, or kitchen, the display is the focal point. With a 4096 x 2304 resolution, this iMac features 9.4 million pixels, which allows for crisp, clear text and support for 4K photos and videos. The IPS panel allows for wider viewing angles so more people can enjoy the Retina 4K display without having to crowd around it. The Retina 4K display also features a wider color gamut for true-to-life color. Moving beyond the typical sRGB display, this iMac features a P3 color gamut, achieved by shifting the Retina 4K display from standard white LEDs to advanced red-green phosphor LEDs. Now all three colors - red, green, and blue - are more equally represented and show off real-world color with more balance and precision.
5th-Gen Broadwell Quad-Core Intel Core Performance
The iMac houses a quad-core 5th-gen Broadwell Intel Core i7 processor. Its quad cores can reach a stock speed of 3.3 GHz. It can also be overclocked up to 3.8 GHz, thanks to Intel Turbo Boost 2.0 technology. The 5th-gen Broadwell Intel processor uses low voltage for better energy efficiency while still providing fast performance. Combined with 16GB of 1867 MHz LPDDR3 onboard RAM, the iMac allows you to multitask quickly and efficiently.
Intel Iris Pro Graphics 6200
With integrated Intel Iris Pro Graphics 6200, the iMac delivers visual effects and 3D graphics that exhibit raw power. The iMac simultaneously supports full native resolution on the built-in display and up to 4096 x 2304 pixels on an external display.
Thin Design
The iMac with Retina 4K display maintains its 5mm profile, which is up to 40 percent less volume than the 2011 iMac. Using an advanced welding method called friction-stir welding, Apple was able to join the front and the back of the iMac together directly.
802.11ac Wi-Fi & Bluetooth 4.0
With three-stream 802.11ac technology, the iMac takes desktop Wi‑Fi speeds over the top. When it's connected to an 802.11ac base station - including AirPort Extreme and AirPort Time Capsule (both sold separately) - you can reach data rates of up to 1.3 Gbps. That's triple the previous 802.11n standard, which means you'll get up to three times faster Wi‑Fi. You also get double the channel bandwidth, with 80 MHz-wide channels providing more room for more data to flow faster than ever. Bluetooth 4.0 wireless technology is also built in, so you can connect accessories such as a wireless keyboard and mouse.
Thunderbolt 2
Expand the capabilities of your Mac. Connect high-performance peripherals. Transfer data at high speed. Even daisy-chain multiple devices. And the iMac with Retina 4K display has Thunderbolt 2, delivering twice the bandwidth - up to 20 Gbps - for fast data transfers. While the Thunderbolt 2 ports double as mini DisplayPorts, the iMac with Retina 4K display cannot be used as a standalone monitor like its predecessor. It can, however, be used simultaneously with an external display and can output up to a 3840 by 2160 resolution.
USB 3.0
With USB 3.0, you can transfer large files in seconds instead of minutes. Every iMac comes with four USB 3.0 ports - with speeds up to 10 times faster than USB 2.0 - and you can connect all your USB-compatible devices, including your iPhone, iPad, iPod or digital camera.

    Apple iMac reviews

    21.5" iMac with Retina 4K Display (Late 2015) is rated 4.8 out of 5 by 12.
    Rated 5 out of 5 by from Great Upgrade, Plenty Powerful for Most People Let me get this out of the way: unless you're trying to run Crysis 3 at 4K on extreme settings, this 21 iMac will do most anything you require. The only reason I did not opt for the larger 27 iMac is the screen was way too big for my preference. The discrete GPU was not enough to sway me this time, and in the past it would absolutely have been.It's no secret that a 3.3GHz quad-core i7 processor and 16GB of RAM will get you very, very far these days on a Mac. While any discrete graphics card is out of the question - I'll address that below - you're getting a whole lot of power for the money here. For example, the GeekBench 64-bit multi-core score I got the other day was 15640, which nearly broke the top 10 list of all Mac scores (including the current Mac Pro), and was nearly on-par with the 4.0 GHz 27 iMac released during the same timeframe (score of 16637). The 2TB Fusion Drive, one I would highly recommend, includes 124GB of flash memory for often-used files. That translates into lightning-fast wake-ups, app launches, logins, and file access, as you'd expect. 16GB of RAM is likely the most you'll need for most of what you do, even if it's potentially memory-intensive. While I was initially wary of the 1.5GB shared GPU in this iMac, it's the latest generation, and everything mentioned in the above paragraph, I've not seen any slow-downs or graphical glitches in my first two weeks using this computer. Though the extent of my hardcore gaming stops at Borderlands 2, Half-Life 2, and Minecraft, I would expect other Mac games like Metro: LL or Doom to fare as well or better. Just don't expect Crysis 3 to run at 4K on extreme settings. You know this is not a computer that can do that well.Now let's talk about the screen - 4K, 4096x2304 pixels. That's a LOT of pixels. Everything is super sharp, especially text. Reading anything is a joy to do on this display. While you might see a few pixels here and there when visiting websites or using apps that aren't retina-ready, it's not a constant headache like some might expect. Only if I get my nose to touch the screen can I discern any pixels otherwise. It's a brand-new visual experience well worth having. How about ports? Even the 21 iMac has a bunch: 4x USB 3.0 at 5Gbps, 2x Thunderbolt 2 at 20Gbps, 1x Gigabit Ethernet, 1x SD Card reader, and 1x Headphone jack. I would recommend a USB 3 hub to expand your ports, especially since the technology is getting so cheap, products like USB 3 hard drive cases and large USB 3 flash drives are in any consumers' reach nowadays. USB 3 is indeed as blazing fast as you'd expect, and paired with the Fusion Drive, transfers and backups no longer take a mind-numbingly long time. Hopefully Thunderbolt gets more affordable in time, but for the time being, FireWire 800 to Thunderbolt adapters are cheap and very useful. Keep in mind USB 3 will not let you daisy-chain other drives through FireWire, though...The Magic Mouse remains generally unchanged as far as I can tell, except for now it's rechargeable directly via Lighting, the same cables that you use to charge newer iPhones and iPads. The new keyboard feels much sturdier, being more of a slab now, with the new keys that make it feel like you're using a touchscreen at times - that is, the keys don't pivot like they used to; instead, regardless of where you press on the key, it will press straight down instead of wobbling to either side like previous iterations' keys. The learning curve is nearly flat, so you'll be typing quickly in no time on this newfangled keyboard. Oh, and the new keyboard charges with Lightning as well. What other miscellany is there? The speakers are a bit more punchy than I expected, but I can't say as an audiophile they're anything but a nice-to-have in a modern desktop computer. FaceTime camera remains generally the same, still 720p if I recall correctly. Packaging is nice, form factor is thin and beautiful, will definitely stand the test of time on my desk with all my other modern technology. Set-up was easy, but a word of caution: do not try to re-format your Fusion Drive. If you try to reformat your Fusion Drive, you're gonna have a bad time. Wifi is very fast as expected, I've not had any issues with that so far. Handoff is really convenient, where for example I'm typing an email on a newer iPhone/iPad and an icon pops up on my iMac's dock prompting me to continue right where I left off on there. Really handy.In closing, coming from a late-2011 Macbook Pro, I am very happy with my purchase and trust this iMac will last many, many years of normal to heavy use. The feature set and internals are enough for most non-professional users, who build the occasional website, Photoshop the occasional photo, and dabble in gaming on weekends. I'm confident I'll continue to enjoy all the future-proofing that went into its design and components until the logic board sputters to a halt in 10 years. It's nice to finally be on USB 3 and 4K - this computer absolutely feels like the future.

    Rated 5 out of 5 by from Love this iMac The screen quality of this 4k 21.5 inch screen is second to no one. The display is so sharp and clear that you will start disliking all other displays you have. The speakers are very good and you won't need any separate desktop speakers unless you want extra bass from a subwoofer. If you're doing any CPU intensive task, the fan makes considerable noise.

    Rated 5 out of 5 by from Easy as pie Ordered my new iMac from B&H as well as some cables to transfer the data from my old iMac (helpful tech at B&H told me exactly which cables I needed). My order arrived on schedule and everything was in excellent condition. Loved that shipping was free too!!! Would do this again when it's time to get my next computer.

    Rated 5 out of 5 by from Super-Fine! This is a great iMac. Maxed out configuration. Beautiful screen full color high resolution - perfect for photography. Used for photography and digital art. Fast and easy. Only downside is the cost but worth it. Couldn't afford the same configuration in the 5K 27 iMac but 21.5 is OK.

    Rated 5 out of 5 by from Quality Product This is a replacement for an older iMac (older display). It came with updated software and was ready to use out of the box. I like the new keyboard and mouse (no batteries). Miss the optical drive but external replacements are easily available.

    Rated 5 out of 5 by from Dream Machine Very pleased with 2TB Fusion/16GB RAM configuration. 4K screen is flat out awesome. Am not a gamer, but do photo editing and general text-intensive work. Integrated graphics works flawlessly for me. I finally made a good choice in my life!

    Rated 4 out of 5 by from Fast and powerfull Great desktop. Fast, great screen. I only wish iMacs had adjustable height, that is why I gave 4 instead of 5 stars. Have not had it long enough to comment on quality, but our other Mac computers have all been flawless.
    Date published: 2016-12-02
    Rated 5 out of 5 by from I should have switched to Mac a long time ago. I added Parallels so I have access to Windows and it works great. It just makes sense to use Mac along with the iPhone and the iPad as they are all connected.
