A big, bold display. Fourth-generation Intel quad-core processors and the latest NVIDIA graphics. An advanced Fusion Drive option. And much more. No desktop has ever brought so much to the table.

Innovations you can see

You won't want anything to distract you from what you're viewing on these big, beautiful 21.5- and 27-inch displays. And nothing will, thanks to an amazing display design that reduces reflection by 75 percent. In addition, because the LCD sits right up against the glass, your content seems to leap off the screen.

IPS technology and LED backlighting

The gorgeous iMac display looks great from any seat in the house. A technology called in-plane switching (IPS) gives you a bright picture with excellent color from nearly any angle. And LED backlighting offers instant-on, uniform brightness with no waiting. So you're always ready to share that vacation slideshow with the family.

Vivid, true-to-life color. Every time

Everything you see on the big, glossy display — from skin tones and dark shadows to bright blue skies and green fields — is rich and vibrant. And the colors are more true to life, too. That's because every iMac display is individually color-calibrated using state-of-the-art spectro radiometers to match color standards recognized around the world.

Powered by fourth-generation Intel Core processors, this iMac is the fastest yet. Every model in the lineup comes standard with a quad-core Intel Core i5 processor, starting at 2.7GHz and topping out at 3.4GHz. And at the Apple Online Store, you can configure your iMac with an even more powerful Intel Core i7 processor, up to 3.5GHz.

iMac graphics are more powerful across the board. NVIDIA GeForce 700 series graphics processors are even faster than the previous generation and include double the video memory. So you'll see more frames per second in 3D games, and you can edit HD home videos with more speed and responsiveness than ever before. And you can get discrete-level performance in the 2.7GHz iMac with integrated Intel Iris Pro graphics.

Advanced Storage Options: Faster Fusion Drive

Fusion Drive is our breakthrough storage option that combines a high-capacity hard drive with high-performance flash storage. And now it's up to 50 percent faster than before. Fusion Drive automatically and intelligently manages your data so that frequently used apps, documents, photos, and other files stay on the faster flash storage, while infrequently used items move to the hard drive. You'll enjoy shorter boot times, and as the system learns how you work, you'll experience faster application launches and quicker file access.

Up to 1TB of flash storage

For maximum performance, you can configure iMac with up to 1TB of flash storage (up to 512GB on the 21.5-inch iMac) instead of a traditional hard drive. This flash storage is now up to 50 percent faster than the previous generation3 and delivers up to 5x the performance of a traditional drive4 — speed you'll notice when you start up your iMac, launch an app, or browse your photo library.

Faster 802.11ac Wi-Fi

iMac now supports ultrafast 802.11ac Wi-Fi. When it's connected to an 802.11ac base station — including the new AirPort Extreme and AirPort Time Capsule — wireless performance is up to 3x faster than with the previous generation of iMac. And your Wi-Fi range improves as well.

Thunderbolt

Ultrafast and ultraflexible, the tiny Thunderbolt port offers unprecedented transfer speeds and incredibly versatile expansion capabilities. Connect high-performance peripherals such as external drives, cameras, audio and video capture devices — even Mini DisplayPort displays for more screen real estate. All iMac models include two Thunderbolt ports, so you can create the ultimate do-anything desktop.

USB 3

Bring on your printer, digital camera, mobile phone, and external hard drive. Every iMac comes with four USB 3 ports — with speeds up to 10 times faster than USB 2 — so you'll have plenty of peripheral possibilities, including your iPhone or iPod, printer, or Apple USB SuperDrive. And the USB 3 ports are fully compatible with your USB 2 devices.

Bluetooth

Bluetooth 4.0 wireless technology is also built in, so you can use your favorite wireless accessories — such as the Apple Wireless Keyboard and Magic Mouse — right out of the box.

Higher-fidelity sound and a larger soundstage

Even though the iMac enclosure is thinner than ever, the built-in speakers deliver higher-fidelity sound than before. So when you're listening to that new album, watching the latest flick, or playing your favorite action game, you'll get immersive sound and a surprisingly wide soundstage.

Dual mics. Be heard loud and clear

iMac has two built-in microphones that work together to home in on your voice and filter out the sounds around you. That means more accuracy when you're using Dictation and better clarity during FaceTime video calls.

FaceTime HD camera for high-resolution video calls

Get everyone in the picture with crisp, widescreen HD video. The built-in 720p FaceTime HD camera lets you make video calls that are so clear, it seems like everyone's in the same room. Make FaceTime calls from your iMac to any FaceTime-enabled Mac, iPhone, iPad, or iPod touch.
