Following the announcement of the iPad Air 2, iOS 8.1 and OS X Yosemite, Apple unveiled the new 27-inch iMac with Retina display. Described as the next step in Retina technology, it boasts what the company calls a Retina 5K display with a massive 5120 x 2880 resolution or 14.7 million pixels. According to Apple, that's 7 times more pixels than your typical 1080p HDTV and 67% more pixels than 4K, making it "the world's highest resolution display."

Apple said it had to create a number of new technologies to drive the display including a custom made timing controller and specifically engineered oxide-based TFT. The company is also implementing some tech from its Retina iPad lineup like organic passivation to accommodate such a massive number of pixels. Apple's new screen tech can power 4 times more pixels while using 30% less energy than previous models by way of high efficiency LEDs. Even with all of the new upgrades it is still 5mm at the thinnest edge, the same as the previous generation models.

The base model 5K Retina iMac will come with a quad-core Intel Core i5 clocked at 3.5GHz (up to 4GHz Core i7), AMD Radeon R9 M290X graphics, 8GB RAM, and 1TB of Fusion Drive storage. It has 2 Thunderbolt ports and has 45% faster graphics than previous models.

The new high res iMac will only ship in a 27-inch model with Apple continuing to offer previous-gen models. The new Retina all-in-one starts at $2499 and is available to order starting today.
