27-inch 5K all-in-one desktop
This 27-inch iMac from mid 2017 combines a 5120 by 2880 Retina display with a 3.4 GHz quad-core Intel Core i5 processor. It ships with 16 GB of 2400 MHz DDR4 memory and a 1 TB Fusion drive running macOS 10.14 Mojave. The integrated AMD Radeon Pro 570 provides 4 GB of video memory for graphics tasks. A wired keyboard and mouse are included in the box.
Thermals acoustics and power in daily use
The all-in-one chassis manages heat from the Kaby Lake processor and Radeon Pro 570 GPU within a single enclosure. Fan noise scales with workload, staying quiet during light productivity and rising under sustained render or compute loads. Power draw reflects the combined display and system components rather than a separate tower and monitor.
Upgrade context and when the jump makes sense
This model replaces earlier non-Retina 27-inch iMacs and lower-spec 5K configurations with slower processors or less memory. The jump is worthwhile for users who need the 5K pixel density for photo or video work and want the convenience of an integrated display. Buyers who need user-replaceable storage or discrete GPU upgrades cannot meet that need with this sealed design.

Questions about this item
How do I install additional memory in the 27-inch 5K iMac and what step is often missed?
The 27-inch model has a memory compartment door on the rear; after inserting the 2400 MHz DDR4 modules you must press each one firmly until it clicks, otherwise the system will not recognise the new RAM.
Which component in the 1 TB Fusion drive is most likely to need replacement first?
The mechanical hard-disk portion of the Fusion drive typically fails before the flash portion, so plan for a future drive swap if you hear unusual noise or see slowdowns.
What thermal limit appears first on the Radeon Pro 570 during long rendering sessions?
The GPU hits its temperature target and reduces clock speeds to stay within its thermal envelope, which shows up as a gradual drop in frame rates during sustained 3D workloads.
