Apple, maker of the iPhones and iPads, definitely wants its customer to have the ultimate desktop experience with the iMac 2015.

The company claims that the iMac 2015 has 14 million more pixels, 62,000 times faster graphics, 1,000 times more RAM, 750 times more storage and 366 times more processing power than the original iMac. Compared with the iMac G3 released in 1998, Apple said it has made a tremendous development.

Yes, that's right. The Cupertino-based tech giant updated the entire iMac family, and here are the important details you need to know about the recent upgrade.
