LED backlighting. One bright idea.
Full brightness with no waiting. That’s the advantage of the LED-backlit iMac display. Unlike displays that take time to warm up before they reach maximum brightness, an LED-backlit display is instantly on and uniformly bright. LED backlighting also lets you finely tune the iMac display to suit the ambient light in even the dimmest room.
More pixels. Better picture.
The 21.5-inch iMac features 1920-by-1080 resolution. The 27-inch iMac boasts even greater resolution of 2560-by-1440. That’s a whopping 78 percent more pixels than the 21.5-inch model. And more pixels mean images look crisp and true to life. A 1000:1 contrast ratio gives you more vibrant colors and blacker blacks. All in a 16:9 aspect ratio — the same as an HDTV.
Next-generation quad-core Intel processors.
Powered by quad-core processors, the new iMac is our fastest yet — up to 70 percent faster than the previous generation. Every model in the lineup comes standard with the latest Intel Core i5 quad-core processor. You even have the option to configure the 21.5- or 27-inch iMac with the Intel Core i7, the fastest quad-core processor available. But why stop there? Add up to 16GB of DDR3 memory and an ultrafast 256GB solid-state drive, and you’ve got an all-in-one that can handle just about anything.
All-new advanced AMD Radeon HD graphics.
With advanced AMD Radeon HD graphics processors across the line, iMac performs even better than before — up to three times better, in fact. 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.
The fastest, most versatile I/O in a desktop.
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. The new 27-inch iMac gives you not just one but two Thunderbolt ports. So in an instant, iMac can go from a family computer to a filmmaker’s dream machine.
The new FaceTime HD camera.
The better to see you with.
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
