Apple iMac 21.5" 2.8GHz Intel Core i5 8GB DDR4 1TB desktop PC

All-in-one desktop with 21.5-inch display

This Apple iMac integrates a 21.5-inch glossy LED-backlit IPS display at 1920x1080 resolution with a quad-core Intel Core i5 processor running at 2.80GHz. It ships with 8GB of DDR4 memory, a 1TB hard drive, and macOS 10.12 Sierra. Connectivity includes four USB 3 ports, two Thunderbolt ports, Gigabit Ethernet, and 802.11n Wi-Fi.

Suits home office and general use.

The integrated Intel Iris Pro Graphics 6200 handles everyday productivity, media playback, and light creative tasks. Buyers who need discrete graphics performance for 3D rendering, modern gaming, or GPU-accelerated compute should consider a different system. The all-in-one form factor also limits internal hardware changes beyond memory.

Memory ceiling of 16GB DDR4

The system supports a maximum of 16GB of DDR4 memory, double the factory 8GB. This cap is the main constraint for users running virtual machines, large datasets, or heavy multitasking workloads. Storage remains on the included 1TB hard drive with no solid-state option mentioned in the specifications.
