The iMac family now includes the 27-inch iMac with Retina 5K display, featuring the world’s highest resolution display. With 14.7 million pixels and a 5120-by-2880 resolution, the new Retina display has four times more pixels than the standard 27-inch iMac and 67 percent more pixels than a 4K display.
The new iMac comes in the same amazing 5 mm-thin aluminum and glass enclosure as the other iMac models. With fourth-generation Intel Core processors, powerful AMD graphics, Thunderbolt 2, Fusion Drive, and OS X Yosemite, the 27-inch iMac with Retina 5K display combines the ultimate display with the ultimate desktop computer.
