PRODUCT DESCRIPTION

The new iMac features next-generation Intel Core i7 quad-core processors and the fastest graphics ever in an all-in-one computer. It also brings Thunderbolt I/O technology to the desktop for lightning-fast data transfer. And a new FaceTime HD camera lets you make full-screen HD video calls. All from a beautiful, widescreen 21.5-inch LED-backlit display that takes up just a sliver of your desk. It's everything you want in a desktop. Now more powerful, more advanced, and even more incredible than before.

The iMac's display offers a 2560 x 1440-pixel resolution (for native 1080p high-definition viewing), and it uses IPS technology to deliver consistent color across an ultra wide 178 degree viewing angle. This 21.5-inch model (Z0M500006) offers improved graphics with AMD Radeon HD 6770M discrete graphics featuring 512MB memory, a 1 TB hard drive, and 8 GB of installed RAM. Other features include integrated Wireless-N Wi-Fi networking, Bluetooth connectivity, an SD card slot (compatible with SDHC and SDXC cards), one Thunderbolt port, a FireWire 800 port, and a total of four USB 2.0 ports (see full specifications below).

Key Features
Next-Generation Dual-Core Intel Processor
This iMac is powered by a second-generation Intel Core i7 quad-core processor (dubbed "Sandy Bridge"), which provides breakthrough digital media management, content creation, and 3D gaming capabilities. With updated Intel Turbo Boost Technology 2.0, the latest Core i7 increases speed automatically for whatever you're doing, dynamically accelerating performance to match your workload.

Intel's Hyper-Threading Technology enables each core of your processor to work on two tasks at the same time, delivering the performance you need for smart multitasking. And you'll enjoy a rich set of new features for a stunning and seamless visual experience with no additional hardware. The "Sandy Bridge" Core i7 processor also provides faster access to the installed RAM, with an integrated memory controller to connect fast 1333 MHz memory directly to the processor.

The iMac's seamless aluminum enclosure and full range of ports, including two Thunderbolt ports (see larger image).Revolutionary Thunderbolt Technology
Developed by Intel with collaboration from Apple, high-speed Thunderbolt I/O (input/output) technology delivers an amazing 10 gigabits per second of transfer speeds in both directions. Built into the iMac, the Thunderbolt port allows you to connect to new Thunderbolt-compatible peripherals as well as existing USB and FireWire peripherals using simple adapters. You'll be able to move data up to 20 times faster than with USB 2.0 and more than 12 times faster than with FireWire 800, and you can daisy-chain multiple high-speed devices without using a hub. Thunderbolt also supports DisplayPort for high resolution displays and works with existing adapters for HDMI, DVI and VGA displays.

Bright, Colorful Display
This 27-inch, all-in-one Apple iMac features an edge-to-edge glass display that utilizes LED backlighting for improved brightness and energy efficiency as well as In-Plane Switching (IPS) technology, which delivers consistent color across a wide 178-degree viewing angle.

Clutter-Free Desktop
You'll be able to cut the cord with the included Wireless Keyboard and Magic Mouse, both of which connect to the iMac using Bluetooth wireless technology. Additionally, the Magic Mouse features a seamless Multi-Touch surface that enables you to use the same intuitive gestures used on the MacBook trackpad to easily scroll through long documents or swipe to move forward or backward through a collection of web pages or photos. And it can be configured as either a single- or two-button mouse.
