Apple iMac Computer

Big, beautiful displays
21.5 and 27 inch displays

Today’s iMac has come a long way from the first

15-inch iMac

. Take one look and you’ll see just how far. A 21.5- or 27-inch display with edge-to-edge glass covers nearly the entire front of the enclosure. When all you see is the display, nothing gets between you and what’s onscreen. Movies, TV shows,

FaceTime HD video calls

, websites, photos — everything looks stunning on the widescreen

16:9 iMac display

.

LED backlighting

The more pixels a display has, the more light those pixels need to achieve the best picture possible. And that’s exactly what the LED backlighting in iMac does: It pushes light through each pixel with remarkable brightness and efficiency. Because the LED backlight doesn’t take up much space, the iMac enclosure stays thin — even with all the high-performance components inside.

High resolution

The

21.5-inch iMac

features 1920-by-1080 HD resolution. Apple engineers could simply have stretched that resolution up and out for the 27-inch iMac. Instead, they took the display well beyond HD with 2560-by-1440 resolution. That’s 78 percent more pixels than the 21.5-inch iMac display.

Seamless enclosure

While you’ll find a collection of ports on the back of iMac, you won’t find much else. A seamless, precision-forged enclosure makes the back one continuous aluminium surface. And there’s only one cord: the power cord.

Cool, quiet components

The

widescreen iMac display

allows more room to separate the two hottest components, the CPU and the GPU. This keeps things cool inside the iMac enclosure. Apple engineers also implemented an intelligent control system that monitors temperatures and delivers just the right amount of airflow to critical components. And the three fans inside iMac have been tuned to be ultra quiet, so you hardly know it’s on.

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.

Thunderbolt
The fastest, most versatile I/O in a desktop

Ultrafast and ultra flexible, 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.

Magic Mouse or Magic Trackpad
Multi-Touch by choice

Now you can choose the perfect cord-free setup. When you buy your new iMac from the Apple Online Store, you have the option to swap Magic Mouse for Magic Trackpad at no extra cost. With Magic Mouse, you can perform simple gestures across its smooth, seamless top shell. Scroll in any direction with one finger, swipe through web pages and photos with two, and click and double-click anywhere. For full gesture support, opt for Magic Trackpad. Made with a touch-friendly all-glass surface, Magic Trackpad is the largest Multi-Touch trackpad made by Apple. So there’s plenty of room for scrolling, swiping, pinching, rotating and then some.

New Intel Core i5 and i7 processors
Up to 1.7x faster at the core.

New quad-core Intel Core i5 processors are standard on the new iMac. Choose a 21.5-inch iMac with a 2.5GHz or 2.7GHz quad-core Intel Core i5. Or expand your view with a 27-inch iMac featuring a 2.7GHz or 3.1GHz quad-core Intel Core i5. You can even configure iMac with the fastest quad-core processor available — the Intel Core i7. All models use Intel’s recently refined chipsets. That means the new iMac performs nearly twice as fast as the previous generation,1 adding a new dimension of speed to everything you do. And since Mac OS X is designed to take advantage of each core, it captures every last bit of performance from the processor.

Turbo Boost 2.0.

Say you’re using a processor-intensive application like Aperture 3 or Final Cut Pro that benefits from extra power. Turbo Boost 2.0 automatically increases the speed of the active cores — up to 3.8GHz. And by shifting core frequency in small increments, Turbo Boost allows the processor to manage performance without sacrificing efficiency. All this takes place behind the scenes, so your work (or play) goes smoother and faster.

Faster single-chip micro-architecture.

Watching a movie, updating your blog, editing photos. Tasks like these require data to travel from place to place. The latest Intel Core architecture puts the processor, cache, memory controller and graphics engine on a single chip. Since data doesn’t have as far to travel, you get faster performance and greater efficiency.

Integrated memory controller.

With faster access to memory, each core gets right to work on your data, rather than waiting for it to arrive. That’s why Intel Core architecture uses an integrated memory controller to connect fast 1333MHz memory directly to the processor. Together with up to 8MB of shared L3 cache, that helps your applications run at peak performance.
