Apple took the 27″ Retina 5K iMac a step further with fifth generation Intel processor technology, state of the art AMD graphics, an even better Retina display with 25% greater color gamut – and at $500 less than the Late 2014 Retina iMac retailed for a year ago.
The Mid 2015 27″ Retina 5K iMac cuts CPU speed and uses a standard hard drive instead of a Fusion Drive to bring the price below the $2,000 mark. (You can upgrade to a Fusion Drive for $200 additional.)
You really have to wonder what Apple was thinking by releasing an iMac with a 5120 x 2880 pixel Retina Display. After all, the regular 27″ iMac already has a 2560 x 1440 pixel display, which goes well beyond HD TV quality.
