Apple announces 27-inch iMac with Retina display, 5,120-by-2,880 pixel resolution

Apple on Thursday revealed the "next step" in Retina display technology by packing what it calls the "world's highest resolution display" into its popular all-in-one desktop.




iMac with Retina 5K display



The all-new iMac with Retina display boasts a 5,120-by-2,880 pixel resolution with a total of 14.7 million pixels crammed into a 27-inch panel, which Apple calls "Retina 5K display."

Compared to a 4K display, Retina 5K has 67 percent more pixels, or seven times the pixels of a normal HD display. The pixel-dense panel is shoehorned into a chassis that is only 5mm thick at its thinnest edge.




Apple needed to invent new technologies to achieve the super high resolution pixel densities in a small package, include oxide TFT, Organic Passivation to reduce cross-talk, new power-efficient LED backlight modules and a completely new timing controller. Despite the new graphics, the new iMac is 30 percent more energy efficient than the previous version.




The new iMac starts shipping today starting at $2,499 with a 3.5 GHz Intel Core i5 processor, AMD Radeon 290X graphics chip, 8GB of RAM and a 1TB Fusion Drive. Build-to-order configurations include a 4 GHz quad-core Intel Core i7 processor with Turbo Boost speeds up to 4.4 GHz, AMD Radeon R9 M295X GPU, up to 32GB of RAM and a 3TB Fusion Drive or 1TB SSD.

Where to Buy



Thew new iMac with Retina 5K display is currently available for order from AppleStore.com and MacMall.com ($2,494.00), with MacMall offering the added benefit of only collecting sales tax in a handful of states.
