Apple iMac 27-inch 5K 3.8 GHz i5 8 GB 1 TB HDD Radeon Pro 580 (Mid 2017)

iMac 27-inch Retina 5K

This all-in-one desktop combines a 27-inch 5120 x 2880 display with a 3.8 GHz quad-core Intel Core i5 processor. It ships with 8 GB of DDR4 memory, a 1 TB hard drive and an AMD Radeon Pro 580 graphics processor. The system includes a USB keyboard and optical mouse and runs macOS 10.13 High Sierra.

Sustained thermal performance

The integrated design houses the processor, graphics and storage behind the 5K panel, so heat dissipation relies on the internal cooling solution under continuous workloads. During extended rendering or compute tasks the quad-core CPU and dedicated GPU share the same thermal envelope. The 8 GB of DDR4 memory and 1 TB hard drive remain active throughout long sessions.

Thunderbolt and connectivity limits

Two Thunderbolt ports provide high-speed peripheral expansion and optional Mini DisplayPort output with adapters sold separately. Four USB 3 ports handle standard accessories while Gigabit Ethernet and 802.11n Wi-Fi manage network traffic. The SDXC card slot supports common media cards and the FaceTime HD camera handles video calls.
