Design: Pixel by pixel, a masterpiece. 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. Apple has pushed the limits of pixel density so you can see everything with pinpoint accuracy. They have questioned every method of integrated design to achieve a remarkable level of fit and finish. The Result? A beautiful, impossibly thin display of colour and contrast - and zero compromise.
Retina Dispaly: 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 colour palette with more accuarcy.( 21.5-inch iMac - 9.4 million pixels; 27-inch iMac 14.7 million pixels).
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, advanced Fusion Drive options, and Thunderbolt 2, iMac delivers lightning fast speed. And striking power.
Processors: Think fast.
A fifth-generation Intel Core processor in the 21.5-inch iMac. An all-new sixth-generation Intel Core processor in the 27-inch iMac - at up to 4.0GHz - and 1867MHz memory. You couldnt ask for more speed. Yet Turbo Boost 2.0 gives you even more when you're using processor-intensive applications like Logic Pro or Final Cut Pro. It all takes place behind the scenes, but you'll see the difference in performance.
Graphics: Images that render you speechless.
The latest AMD high performance graphics give the 27-inch iMac with Retina 5K display up to 3.7 teraflops of graphics compute power. The 21.5-inch iMac with Retina 4K display also lights up with enhanced Intel Iris Pro Graphics. Both deliver visual effects and 3D graphics that exhibit raw power in its most polished form. (Up to 4GB GDDR5 memory).
Fusion Drive: 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. Whatever the choice, everything from booting up to launching apps to importing photos is faster and more effecient. Thats 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 3TB Fusion Drive)
