Thunderbolt 2. Blazing-fast data transfer.
Each 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.
iCloud. Everything you love on your iMac. On all your devices.
iCloud stores your content and lets you access your music, photos, calendars, contacts, and more from whatever device you're using. And with iCloud Drive, you can safely store all your presentations, spreadsheets, PDFs, images, and any other kind of document in iCloud - and access them from your iPhone, iPad, iPod touch, Mac, or PC.
5 millimeters thin. Just the right size to do something big.
The 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. Today's iMac includes the most advanced, most brilliant desktop display we've ever built, and it's filled with the latest high-performance technologies. Yet it's still just 5 mm thin at its edge.
Retina Display
Every millimeter of the Retina display was designed, engineered, and built to the most exacting standards. Something that 9.4 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.
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. 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.
Fifth-generation Intel Core processors.
The 21.5-inch iMac features a fifth-generation Intel Core processor and enhanced Intel Iris Pro Graphics. Both deliver stirring visual effects with maximum impact - at maximum speed.
