Fastest quad-core processor: Compared with the original generation, the new one iMac features nearly twice the processing speed. It runs the latest 2.7-GHz quad-core Intel Core i5 processor or the Intel Core i7, as well as 4GB of RAM, a 1TB hard drive, and an AMD HD 6770M (512MB) GPU. Such powerful configuration allows you to handle just about anything.
Fastest graphics: The new iMac has also added the advanced AMD Radeon HD graphics processor, the Radeon HD 6000-series. With the AMD Radeon HD 6970M plus 2GB GDDR5 memory, the 27-inch iMac offers the best graphics of any all-in-one, up to 3x faster than before. So you are able to enjoy a more pleasant gaming experience, even 3D games.
Built-in FaceTime HD camera: The new iMac also comes in Apple’s FaceTime software, so users can now use the iMac to chat with their friends and family using iPad 2, iPhone 4, or iPod touch. The new FaceTime HD camera lets you make the widescreen FaceTime video calls in 720p resolution, clear and convenient.
Thunderbolt: Another exciting new feature is the additional Thunderbolt port. As is known that, Thunderbolt has a claimed 10Gbps of data transfer speeds, which is twice as fast as the current USB 3.0 standard. The new 27-inch iMac gives users two Thunderbolt ports, ultrafast and ultraflexible.
New iMac 2011: 21.5- and 27-inch iMac Pros & Cons Reviews
iMac Cons:
Undeniably, the new 27-inch iMac offers the best all-around performance among all-in-ones. But there still something imperfect. First, it misses built-in HDMI inputs for easy media component integration, and, as usual, custom hardware options for the iMac remain more expensive than those for its Windows-based competition. Then, the iMac’s 3.1GHz Core i5 2400 CPU lacks HyperThreading, and thus remains a pure quad-core processor.
Furthermore
In addition, apart from Wireless Keyboard, Apple has also offered Magic Mouse and Magic Trackpad for your choice, suiting your iMac.
Plus, the 21.5-inch iMac will start at $1,199 and be configured with a 2.5-GHz quad-core Intel Core i5 processor, 4GB of RAM, a 500GB hard drive, and an AMD Radeon HD 6750M (512MB) GPU.
