Apple has updated its lineup of systems featuring Thunderbolt interconnection technology on Tuesday by updating its iMac lineup of all-in-one desktop computers. The new PCs are powered by quad-core Intel Core i-series "Sandy Bridge" microprocessors and feature discrete AMD Radeon HD 6000-series graphics adapters.
The family of iMac 2011 systems includes various 21.5" (1920*1080) as well as 27" (2560*1440) models, all of which are powered by Intel Corp.'s latest quad-core Core i "Sandy Bridge" chips with 6MB of cache that offer enhanced performance in various applications. The new iMacs feature AMD's latest Radeon HD 6700M-series (up to 480 stream processors) or Radeon HD 6970M (up to 960 stream processors) discrete graphics cards in MXM form-factor. Just like predecessors, the new Macintosh PCs come with 4GB of DDR3 memory and up to 2TB hard disk drive.
One of the important things about the new iMac customers is that they are equipped with one or two Thunderbolt connectors as well as SD XC card readers. The addition of the new interconnection technology will catalyze more manufacturers to consider its addition to devices that can take advantage of up to 10Gb/s of bandwidth.
Unfortunately, Apple decided not to equip its new iMac computers with Blu-ray disc drives, which greatly limits their multimedia capabilities. Apple also did not adopt USB 3.0, an interconnections standard with up to 5Gb/s of bandwidth, which is by far more popular than Thunderbolt.
The new Apple iMac 2011 systems cost from $1199 to $1999 in stock configurations. Versions of iMac with enhanced performance will cost higher amounts of money.
