Apple weds high-res 5K visuals into its sleek 27" iMac with Retina 5K Display (Early 2019). With a 5120 x 2880 screen resolution, this iMac provides one billion colors and 500 nits of brightness. The Retina 5K display also features the wider P3 color gamut, which provides a larger color space that shifts away from standard white LEDs to red-green phosphor LEDs that more equally represent red, green, and blue. And with more available colors, the images will appear more vivid and reveal greater detail, with more balance and precision.
The iMac's processor has been upgraded and now houses an 8th-gen 3.1 GHz Intel Core i5 Six-Core processor that can be overclocked up to 4.3 GHz, as well as 8GB of 2666 MHz DDR4 RAM in a 2 x 4GB configuration that can be upgraded to 64GB by using a 16GB module in each of the four SO-DIMM slots. Visuals are powered by a dedicated AMD Radeon Pro 575X graphics card with 4GB of GDDR5 video memory, and for storage, there is a 1TB Fusion Drive.
Outfitted with Wi-Fi 5 (802.11ac) and backwards compatible with 802.11a/b/g/n for speedy hook-ups to your home network, this iMac is also configured with Bluetooth 4.2, as well as an SDXC card slot, two 40 Gb/s Thunderbolt 3 ports, four 5 Gb/s USB 3.0 Type-A ports, a Gigabit Ethernet jack, and a FaceTime HD camera. It also has a Kensington lock slot for added security.
