Description

The 2015 iMac features one ofbest displays, paired with high-performance processors, graphics, and storage all within an incredibly thin, seamless enclosure. Itdelivers such spectacular image quality that everything else around you seems to disappear. This version packs in a 5th generation 2.8GHz quad-core Intel Core i5 processor with 8GB ofonboard memory, a 1TB hard drive, and a brilliant 1920-by-1080 pixel LED-backlit display.Adding up to the most immersive iMac experience yet and another big, beautiful stepforward.Captivating Retina DisplayEvery 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. Its that attention to detail that inspired the all-new 21.5inch iMac with Retina 4K display. And just like the Retina 5K display, it delivers a larger color palette with more accuracy.Many of the brilliant, unique colors you see in the real world never make it to your screen. A wider color gamut makes more of these real-life colors available on the Retina display. A striking 25percent more. So whether its a sunset at the beach or your favorite football teams jerseys, youll see them just as you saw them on a display thats more vibrant thanever.Incredibly Thin, Seamless DesignThe first iMac was a revolution: An all-in-one computer that put everything display, processor, graphics, storage, memory, and more inside one simple, stylish enclosure. Todays iMac includes the most advanced, most brilliant desktop display Apple has ever built, and its filled with the latest high-performance technologies. Yet its still just 5 mm thin at its edge.One of the biggest challenges Apple engineers faced with the iMac enclosure was how to join the front to the back. The enclosure is so thin, its not possible to weld the pieces using traditional methods. So they utilized a process called frictionstir welding. It combines intense friction-generated heat and pressure to intermix the molecules of the two aluminum surfaces creating a seamless, precise, and incredibly strong bond.Ultimate Processing PowerA fifth-generation Intel Core processor in the 21.5-inch iMac, you couldnt ask for more speed. Yet Turbo Boost2.0 gives you even more when youre using processor-intensive applications like Logic Pro or Final Cut Pro. It all takes place behind the scenes, but youll see the difference inperformance.The 21.5-inch iMac with Retina 4K display also lights up with enhanced Intel Iris Pro Graphics delivering visual effects and 3D graphics that exhibit raw power in its most polishedform.Blazing-fast Data TransferEach of the two ultrafast, ultraflexible Thunderbolt 2 ports significantly expand the capabilities of iMac. For example, you can connect high-performance peripherals and move data up to 40 times faster than with USB 2, and up to 25 times faster than with FireWire 800. You also have more than enough bandwidth up to 20 Gbps to daisy-chain multiple high-speed devices and still maintain maximum throughput.Up To Three Times Faster WiFiWith 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 Thats 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.
