Apple iMac 21.5" Retina 4K i5-8500 8GB 1TB MRT42LL/A

21.5-inch Retina 4K all-in-one

The 2019 Apple iMac combines a 3.0 GHz Intel Core i5-8500 six-core processor with a 4096x2304 display in a single silver chassis. It ships with 8 GB of 2666 MHz DDR4 memory and a 1 TB hard drive. The Radeon Pro 560X graphics card provides 4 GB of dedicated video memory. This configuration suits home-office users who want a tidy desk setup without separate components.

Radeon Pro 560X and Thunderbolt 3 ports

The discrete Radeon Pro 560X GPU handles creative workloads and light gaming better than integrated graphics alone. Two Thunderbolt 3 ports deliver up to 40 Gb/s bandwidth for fast external storage or high-resolution displays. Four USB 3.0 ports, Gigabit Ethernet and a 3.5 mm headphone jack complete the wired connectivity. No internal SSD is present, so boot and application launch speeds rely on the mechanical drive.

Mechanical drive and fixed memory limits

The 1 TB hard drive offers capacity but lacks the access speed of solid-state storage, which affects system responsiveness. Memory is not user-upgradable after purchase, locking the system at 8 GB for its lifespan. The 21.5-inch panel does not support touch input. Buyers who need faster storage, more than 8 GB of RAM or a touchscreen should consider alternative form factors.
