iMac from Apple Computer now with ultimate display of 21.5 and 27 inches

 iMac The Ultimate All-in-One with ultimate display of 21.5 and 27 inches.

With available quad-core processors and advanced graphics, the new iMac is the fastest, most powerful iMac yet.

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 doesn’t have to travel far to get from core to core. This boosts application performance up to 2x over the previous-generation iMac.¹ 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.²

Turbo Boost.

A quad-core iMac also benefits from Turbo Boost. If you’re using an application that doesn’t 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 you’re 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.³ For the ultimate in graphics performance, choose a 27-inch iMac with the ATI Radeon HD 4850 graphics processor.
