iMac has always harnessed the latest technology and taken it further to make the ultimate all-in-one better and better. And the Retina display is a testament to that. We pushed the limits of pixel density so you can see everything with pinpoint accuracy. We questioned every method of integrated design to achieve a remarkable level of fit and finish. The result? A beautiful, impossibly thin display of color and contrast and zero compromise.

Precision. Repeated 14.7 million times.

Every millimeter of the Retina display was designed, engineered, and built to the most exacting standards. Something that 14.7 million pixels makes exceedingly clear. As does a 1.4 mm thin display panel designed around the human eye so every interaction feels as natural as can be. It’s that attention to detail that inspired the all-new 21.5‑inch iMac with Retina 4K display. And just like the Retina 5K display, it delivers a larger color palette with more accuracy.

Built for speed. And everything else.

You know iMac by its incredibly thin enclosure. But that just sets the stage for massive performance. With a new Intel Core processor, the latest AMD graphics, an advanced Fusion Drive, and Thunderbolt 2, iMac delivers lightning-fast speed. And striking power.

A fusion of storage, speed, and intelligence.

Fusion Drive combines the spaciousness of a traditional hard drive with the high performance of flash storage. Choose a swift 1TB Fusion Drive or a lightning-fast version with up to 3TB of storage.1 Whatever the choice, everything from booting up to launching apps to importing photos is faster and more efficient. That’s because your frequently used items are kept at the ready on speedy flash storage, while infrequently accessed items go to the hard drive. It’s the best of both worlds.

Up to three times faster Wi‑Fi.

With three-stream 802.11ac technology, iMac takes desktop Wi‑Fi to unprecedented speeds. Simply connect to an 802.11ac base station — such as AirPort Extreme or AirPort Time Capsule and reach data rates of up to 1.3 Gbps.3 That’s triple the previous 802.11n standard. You also get double the channel bandwidth, with 80MHz-wide channels providing more room for more data to flow faster than ever.
