Apple weds high-res 5K visuals into its sleek 5mm thin 27" iMac with Retina 5K Display. With a 5120 x 2880 native resolution, this iMac provides 14.7 million pixels, which is 7 times more than the standard HD display. The Retina 5K display also features a wider color gamut. Using a P3-based color gamut, the Retina 5K 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 6th-gen Skylake 4.0 GHz Intel Core i7 processor with 16GB of 1867 MHz DDR3 RAM. The iMac also has an AMD Radeon R9 M395X graphics card with 4GB of GDDR5 vRAM. For storage, the iMac has a 3TB 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.
The iMac runs the Mac OS X El Capitan operating system. Built on a solid UNIX foundation, El Capitan is engineered to take full advantage of the iMac's hardware. It features performance improvements and updates to built-in apps. El Capitan was specifically designed for the Retina display and features a system font called San Francisco that has been fine-tuned for optimal readability on a Retina display.
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.
Please note that this model is only for use with VESA wall-mounts, which are sold separately. A VESA mount adapter is included with the iMac.
