Big, beautiful displays.

21.5-inch and 27-inch displays.

The new iMac has come a long way from the first 15-inch iMac. Take one look and youll see just how far. A 21.5-inch 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 whats onscreen. Movies, TV shows, websites, photos - everything looks stunning on the new 16:9 widescreen iMac display.

LED backlighting.

When a display has more pixels, you need to push more light through them to achieve the best picture possible. LED backlighting in the new iMac does exactly that, with remarkable brightness and efficiency. Because the LED backlight doesnt take up much space, the iMac enclosure stays thin - even with all the high-performance components inside.

Higher resolution.

The new 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. Thats 78 percent more pixels than the 21.5-inch iMac.

IPS technology.

The iMac display is designed to look great from almost any angle. A technology called in-plane switching (IPS) makes this possible. Whether youre sitting in front of the display or standing off to the side, youll get a perfect picture with superb color consistency and no loss of detail.

Evolution of iMac.

It was a great idea then, and its a great idea now. The all-in-one design of the first flat-panel iMac cleaned up the desktop. It put everything you need - display, processor, graphics card, hard drive, optical drive, memory, and more - inside one simple enclosure. New technology inside and out makes the new iMac a worthy addition to the all-in-one dynasty.

Seamless enclosure.

While youll find a collection of ports on the back of iMac, you wont find much else. A seamless, precision-forged enclosure makes the back one continuous aluminum surface. And theres only one cord: the power cord.

Cool, quiet components.

The wider 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 ultraquiet. The result of all this tinkering with heat and sound? A system that operates at 18 decibels when idle - so quiet, you hardly know its on.

The glass that surrounds the LED-backlit display wraps around the edge of the aluminum enclosure.

Another victory over clutter, the finely tapered aluminum pedestal practically disappears on the desktop.

New speakers deliver louder, clearer sound with better bass response and less distortion.

Clutter-free wireless.

iMac embodies simple design that eliminates desktop clutter. So naturally, its the first Mac to come standard with the Apple Wireless Keyboard and the new wireless Magic Mouse.

Multi-Touch technology.

Magic Mouse is designed to do all the things a mouse should do - pointing, clicking, and scrolling - but with no scroll wheel, no trackball, and no visible button. Magic Mouse uses Multi-Touch technology to let you click, scroll, or swipe anywhere on its perfectly smooth, seamless top shell. But the real magic of Magic Mouse is how it knows what you want to do. A chip inside Magic Mouse acts as a brain, detecting the difference between a resting hand, a scrolling finger, a two-finger swipe, and a simple click. Its the smartest mouse weve ever made.

Faster processors.

Quad-core power.

The available quad-core Intel Core i5 or Core i7 “Nehalem” processor in the 27-inch iMac puts four processing cores on one die, so data doesnt have to travel far to get from core to core. This boosts application performance up to 2x over the previous-generation iMac. And unlike systems that connect memory to the processor through a separate controller, these quad-core processors connect memory directly to the processor, improving memory bandwidth up to 2.5x.

Turbo Boost.

A quad-core iMac also benefits from Turbo Boost. If youre using an application that doesnt need every core, Turbo Boost shuts off the idle cores while simultaneously increasing the speed of the active ones.

Built for more cores.

Mac OS X Snow Leopard is designed to take advantage of this advanced processor architecture, so every Intel processor reaches its full potential on iMac.

Faster graphics.

Options for everyone.

iMac offers graphics options designed to make the most of every pixel. Whether youre an amateur filmmaker or an avid gamer, iMac gives you faster, smoother, clearer graphics across the board.

Start with advanced graphics.

The 21.5-inch iMac offers great graphics performance with the integrated NVIDIA GeForce 9400M graphics processor or the ATI Radeon HD 4670. The 27-inch iMac comes with dedicated high-performance ATI graphics across the line.

Upgrade to top-of-the-line graphics.

The ATI Radeon HD 4670 graphics processor delivers up to 4x faster performance than the NVIDIA GeForce 9400M - ideal for 3D games and graphics-intensive applications. For the ultimate in graphics performance, choose a 27-inch iMac with the ATI Radeon HD 4850 graphics processor.

iMac does more, faster.

Viewing and editing photos.

The new iMac is faster at importing photos and performing basic editing tasks - things like removing red-eye and erasing small blemishes - in iPhoto. If youre a photo fanatic who loves the power and precision of more professional applications, the 2.8GHz quad-core iMac gives you up to 2x faster performance with Aperture.

Productivity.

iMac makes quick work of work. Create complex transitions in a Keynote presentation. Add 3D charts to a Numbers spreadsheet. Design a beautiful document in Pages. Powerful Intel processors across the iMac line make iWork fast and responsive.

Video editing.

Shot some video you want to edit fast and share with friends? Large iMac displays and powerful processors are perfect for editing and stabilizing shaky video in iMovie. For more complex editing and encoding tasks, upgrade to the 2.8GHz quad-core processor and get up to 2.3x faster performance with Final Cut Studio.

Playing games.

Games scream on iMac, thanks to advanced ATI graphics. The discrete ATI Radeon HD 4670 processor delivers up to 4.4x faster performance than the integrated NVIDIA GeForce 9400M processor. Thatll keep you on your game, even inside the complex 3D environments of Call of Duty 4 or Doom 3. Or choose the ATI Radeon HD 4850 processor for the ultimate in iMac graphics performance.
