The iMac display looks great from any seat in the house, thanks to a premium display technology called in-plane switching (IPS). IPS gives you a bright picture with excellent color - even if you're viewing the display from the side. The 21.5-inch iMac features 1920-by-1080 resolution. The 27-inch iMac boasts even greater resolution of 2560-by-1440. All in a 16:9 aspect ratio - the same as an HDTV.
Powered by quad-core processors, the new iMac is our fastest yet — up to 70 percent faster than the previous generation.4 Every model in the lineup comes standard with the latest Intel Core i5 quad-core processor.
With advanced AMD Radeon HD graphics processors across the line, iMac performs even better than before — up to three times better, in fact.5 So you see more frames per second in 3D games, and you can edit HD home videos with more speed and responsiveness than you ever thought possible.
Ultrafast and ultraflexible, the Thunderbolt port features two 10-Gbps data channels for data transfer that’s up to 12 times faster than FireWire 800 and up to 20 times faster than USB 2.0. And it offers unprecedented expansion capabilities for a new generation of high-performance peripherals.
Get more of your friends in the picture with crisp, widescreen HD video. The new FaceTime HD camera lets you make FaceTime video calls in 720p resolution. The picture is so clear, it will look and feel almost like you’re in the same room. Make HD calls from one new iMac to another or to a new MacBook Pro. You can also make video calls to other Intel-based Mac computers, iPad 2, iPhone 4, or the latest iPod touch.6
