Apple iMacs

The iMac comes in 21.5-inch and 27-inch sizes.

Apple has released an update to its iMac range of all-in-one PCs. The update comprises hardware upgrades, the addition of an HD webcam and the introduction of the new Thunderbolt PC connection.

There are four base versions of the new iMacs, two with a 21.5-inch screen and two with a 27-inch screen. 

Prices start at £999 and even the cheapest model features an Intel quad-core processor – a feature that should allow iMacs to perform more tasks simultaneously without a loss of performance. 

Apple has also upgraded the graphics on the iMacs, claiming that 'the new iMac has the most powerful graphics ever in an all-in-one desktop'.

Also new is the addition of an HD webcam, which Apple calls the FaceTime HD camera, and the introduction of the Thunderbolt ports – one on 21.5-inch models, two on 27-inch models.

What is Thunderbolt?

Thunderbolt is a new type of PC connection that Apple first introduced on its latest MacBooks, and which promises transfer speeds far in advance of other connections such as USB 3.0. Read our guide to Thunderbolt and USB 3.0 for more information.

All the new iMacs are on sale on Apple's web store now.
