Everything you need to know about the 27-inch iMac and its 5K Retina display

“Thirty years after the first Mac changed the world, the new iMac with Retina 5K display running OS X Yosemite is the most insanely great Mac we have ever made,” said Philip Schiller, Apple’s senior vice president of Worldwide Marketing. “With a breathtaking 14.7 million pixel display, faster CPU and graphics, Fusion Drive, and Thunderbolt 2, it’s the most beautiful and powerful iMac ever.”

The iMac’s Retina 5K display delivers a resolution of 5120 x 2880 pixels, “four times more pixels than the standard 27-inch iMac and 67 per cent more pixels than a 4K display”.

iMac with Retina 5K display uses a precisely manufactured oxide TFT-based panel to deliver vivid display brightness from corner to corner. A single supercharged Apple-designed timing controller (TCON), with four times the bandwidth, drives all 14.7 million pixels.

“iMac with Retina 5K display also uses highly efficient LEDs and organic passivation to improve image quality and reduce display power consumption by 30 per cent, even while driving four times more pixels at the same brightness. To improve the contrast ratio, iMac with Retina 5K display uses a new photo alignment process and a compensation film to deliver blacker blacks and more vibrant colours from any viewing angle,” said a release. In addition, every iMac with Retina 5K display is calibrated using three state-of-the-art spectroradiometers to ensure precise and accurate colour.

The new iMac comes with a 3.5 GHz quad-core Intel Core i5 processor with Turbo Boost speeds up to 3.9 GHz, and for the first time can be configured with a 4 GHz quad-core Intel Core i7 processor with Turbo Boost speeds up to 4.4 GHz. It has AMD Radeon R9 M290X graphics and can be configured with AMD Radeon R9 M295X graphics too, delivering up to 3.5 teraflops of computing power, the most powerful graphics ever offered on an iMac.

iMac with Retina 5K display comes standard with 8GB of memory and a 1TB Fusion Drive for the first time. The new iMac can also be configured with up to 32GB of memory, a 3TB Fusion Drive, or up to 1TB of super-fast, PCIe-based flash storage. In addition, iMac with Retina 5K display includes two Thunderbolt 2 ports that deliver up to 20Gbps each, twice the bandwidth of the previous generation.

Every new Mac comes with OS X Yosemite, a powerful new version of OS X, redesigned and refined with a fresh, modern look, powerful new apps and amazing new Continuity features that make working across your Mac and iOS devices more fluid than ever.

iMovie, GarageBand and the suite of iWork apps come free with every new Mac. iMovie lets you easily create beautiful movies, and you can use GarageBand to make new music or learn to play piano or guitar.
