21.5-inch versus 27-inch
Screen size is not the only difference. Display resolution, upgrade options and ports also vary. Some 27-inch models have a Retina 5K display; verify the technical specifications for the exact year and configuration.
Buying a used Intel iMac
Compare used 21.5-inch and 27-inch Intel iMac models by year, display, processor, RAM, SSD or Fusion Drive and physical condition.
What to know before you decide
Intel iMacs span many years and configurations. A 2014 or 2015 unit is very different from a 2019 or 2020 model. Identify the exact machine before comparing prices or assuming software compatibility.
SSD, hard drive or Fusion Drive
Storage type can have a large effect on day-to-day responsiveness. Ask whether the specific unit has an SSD, mechanical drive or Fusion Drive, and confirm capacity and condition.
Processor, RAM and software
Confirm the model year, Intel Core processor and installed RAM. Support for recent macOS versions and applications depends on the exact model, so check the software you need before committing.
Physical inspection
Check the screen, fans, ports, Wi-Fi, Bluetooth, camera, sound and accessories. Do not assume that a currently available iMac has the same condition as a sold reference listing.
Frequently asked questions
Can every Intel iMac be upgraded?
No. Upgrade options depend on the exact model. Verify the specification before relying on a future memory or storage upgrade.
How do I compare an Intel iMac with an M1 model?
Compare the applications you need, display, memory, storage, connectivity, physical condition and total price. Chip generation alone is not the whole decision.
