The new iMac is astoundingly thin, with its edge measuring just 5mm thick. While the display is not Retina, it does featured an IPS panel for improved viewing angles, and reflection has been reduced by 75%. The display also adopts an optical bonding technique similar to that used in the iPhone 5, which allows for such a thin design.
With the next generation iMac, Apple is also introducing a new hardware feature called Fusion Drive. Fusion Drive uses software to combine a flash-based 128GB SSD and standard disk-based 1TB or 3TB hard drive into a single drive. The operating system and built-in software are stored on the SSD for optimal system performance, while files and other applications are stored on the HDD. OS X then adapts to your usage patterns, and will automatically move files and applications you use most often onto the SSD for faster performance. It’s a neat feature, and one that pro users will undoubtedly enjoy.
The next-generation iMac will be available in both 21.5-inch and 27-inch screen sizes. The base 21.5-inch model packs a 2.7 GHz quad-core Intel Core i5, NVIDIA GeForce GT 640M, 8BG of RAM, and a 1TB hard drive for $1299, while the high-end 21.5-inch model gets bumped up to a 2.9GHz quad-core Intel Core i5 processor with NVIDIA GeForce 650M graphics for $1499. Meanwhile, the 27-inch model starts with a 2.9GHz quad-core Intel Core i5 processor, 8GB of RAM, 1TB hard drive, and NVIDIA GeForce GTX 660M graphics for $1799, with the high-end model getting a 3.2GHz quad-core Intel Core i5 processor, and NVIDIA GeForce GTX 675MX graphics processor for $1999. The Fusion Drive option is only available for the high-end 21.5-inch model and both 27-inch variants.
The new 21.5-inch iMac will start shipping in November, with the 27-inch model to follow sometime in December.
