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 3.1 GHz Intel Core i5 processor with 8GB of 1867 MHz LPDDR3 onboard RAM and integrated Intel HD Graphics 6200. For storage the iMac has a 1TB 5400 rpm HDD.

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. Youll 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 i5 processor. Its quad cores can reach a stock speed of 3.1 GHz. It can also be overclocked up to 3.6 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 8GB 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 its 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. Thats triple the previous 802.11n standard which means youll 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.
