Apple has updated its entire iMac family, introducing a new Retina 4K display to the 21.5-inch iMac for the first time and the Retina 5K display to every 27-inch iMac. The new Retina displays make photos and videos more true-to-life thanks to a wider color gamut and high image quality.

The 21.5-inch iMac is available with the all-new Retina 4K display featuring a 4096 x 2304 resolution and 9.4 million pixels, 4.5 times more than the standard 21.5-inch iMac display. Every 27-inch iMac features a Retina 5K display, the world’s highest resolution all-in-one display with 14.7 million pixels, 7 times more pixels than an HD display.

The updated 27-inch iMac also features sixth-generation Intel Core processors and the latest AMD high-performance graphics. The new 21.5-inch iMac with Retina 4K display features a fifth-generation Intel Core processor and enhanced Intel Iris Pro Graphics.

Two Thunderbolt 2 ports now come standard on all iMacs and deliver up to 20Gbps data transfer speeds for external drives and peripherals. And three stream 802.11ac Wi-Fi allows iMac to support up to 1.3Gbps wireless networking.

Fusion Drive combines the large storage capacity of a hard drive with the high performance of flash to deliver shorter boot times and faster access to apps and files. Fusion Drive works in conjunction with OS X to adapt to the way you use your iMac and automatically moves the files and apps you use most often to flash storage. The incredible performance of Fusion Drive is now more affordable with a lower-priced configuration that pairs a 1TB hard drive with 24GB of fast flash. Fusion Drive is also available with 2TB and 3TB configurations with 128GB of fast flash for more demanding workloads. And if you need even more storage performance, optional all flash storage is available up to 1TB and is now up to 2.5 times faster.

Designed around a built-in rechargeable lithium-ion battery, all three accessories eliminate the need for disposable batteries and feature more solid internal structure.
