New Apple iMac 27 inch All-In-One Desktop PC (Intel Core i5 3.1GHz Quad-Core Processor, 2X2GB RAM, 1TB HDD, AMD Radeon HD 6970M with 1GB graphics) (Launched May 2011)

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 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.

Stunning from every angle

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.

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 -a 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

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

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.

It’s very well connected.

Thunderbolt

The new Thunderbolt port lets you daisy-chain as many as six devices plus an additional display. So with just one port you can create the ultimate do-anything desktop. If you choose the new 27-inch iMac, a second Thunderbolt port lets you expand even more. And since Thunderbolt is based on DisplayPort technology, you can plug any Mini DisplayPort display right into the Thunderbolt port.

USB and FireWire

Bring on your iPad, iPod, digital camera, mobile phone, and external hard drive — there’s no shortage of ports on iMac. Four USB 2.0 ports and a FireWire 800 port give you plenty of peripheral possibilities.

Wi-Fi and Bluetooth

The latest 802.11n wireless technology in iMac makes it effortless to connect to a Wi-Fi network. iMac automatically finds available networks and lets you join them with a click. Bluetooth wireless technology is also built in, so you can use your favorite wireless accessories right out of the box.

SDXC

Transfer photos and videos to your iMac as fast as you take them. The built-in SDXC card slot supports SD and SDHC cards with capacities up to 2TB. Just insert your camera’s memory card and import your photos to iPhoto.
