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. That’s 78 percent more pixels than the 21.5-inch iMac. The iMac display is designed to look great from almost any angle. A technology called in-plane switching (IPS) makes this possible. iMac embodies simple design that eliminates desktop clutter. So naturally, it’s the first Mac to come standard with the Apple Wireless Keyboard and the new wireless Magic Mouse.
The 21.5-inch and 27-inch iMac models offer fast Intel Core 2 Duo processors up to 3.33GHz. Quad-core power comes to the 27-inch iMac with a 2.66GHz Intel Core i5 processor or 2.8GHz Intel Core i7 processor. Four cores deliver up to 2x faster performance for just about everything you do: managing your photos, editing HD video, even playing graphics-intensive 3D games. And since Mac OS X Snow Leopard is designed to take full advantage of Intel dual- and quad-core architectures, you get the fastest performance possible.
Every iMac comes with high-performance graphics that make games run smoother, photos load faster, and pro applications work better. If you want even speedier graphics, choose an iMac with a more advanced ATI graphics processor.
