Apple has launched a new iMac line-up, with a brand new, massively thinner design. Here, you can find out all of the tech specs and pricing of the new models.

All of the new models come with a standard of 8GB of 1600 MHz memory and a 1TB hard drive, which can be configured with up to 32GB of memory and a new 3TB hard drive, or 768GB of flash storage. They also have two Thunderbolt ports and four USB 3.0 ports.

Apple has also introduced a new storage option called Fusion Drive. "Fusion Drive is an innovative new storage option that gives customers the performance of flash storage and the capacity of a hard drive. It combines 128GB of flash with a standard 1TB or 3TB hard drive to create a single storage volume that intelligently manages files to optimise read and write performance. Fusion Drive adapts to the way you use your iMac and automatically moves the files and apps you use most often to flash storage to enable faster performance and quicker access," says Apple in its press release.

Apple says that the new iMac's display has 75 pert cent less reflection than previous models. Apple has also made the LCD 5mm thinner, and has used a process called 'full lamination' to remove the 2mm gap between the LCD and the glass, meaning that viewers are now "closer to the action".

The iMac is available in 21.5in and 27in models, and pricing starts at £1,099.

The 21.5in iMac with 2.7 GHz quad-core Intel Core i5 and NVIDIA GeForce GT 640M is the starting model, at £1,099, and will be available in November.

Also coming in November is a 21.5in model with a 2.9 GHz quad-core Intel Core i5 and NVIDIA GeForce GT 650M for £1,249.

The 27in iMacs will begin shipping in December. The 2.9 GHz quad-core Intel Core i5 model with NVIDIA GeForce GTX 660M will cost £1,499, and the 3.2 GHz quad-core Intel Core i5 and NVIDIA GeForce GTX 675MX model will cost £1,699.

The latest NVIDIA GeForce processors are said to be 60 per cent faster for gaming and graphics intensive apps.
