Apple announced Tuesday an update to its line of desktop computers, introducing the retina display made available on its iPhones and iPads.

The 21.5-inch iMac will boast a 4K retina display, while the 27-inch model features a 5K display. The models also boast upgrades to its processors and graphics.

“These are the most stunning iMacs we’ve ever made,” says Apple marketing chief Philip Schiller in a statement.

The 21.5-inch iMac starts at $1,099, while the 27-inch starts at $1,799.

The revamped iMacs arrive as sales of personal computers continue to slump. According to third quarter results from research firms IDC and Gartner, shipments fell as the strength of the U.S. dollars made PCs more expensive to purchase in other countries.
