All-in-one desktop for creative work
The Apple iMac 21.5 Retina 4K (Late 2015) combines a 21.5-inch display with a 3.1GHz Intel Core i5 quad-core processor and 8GB of LPDDR3 memory. It targets creative professionals and everyday users who want a space-saving system with integrated visuals. The 1TB 5400rpm hard drive stores documents, media and applications. This unit is supplied in new condition.
Retina 4K display and connectivity limits
The 4096×2304 Retina 4K panel delivers ultra-sharp visuals and vibrant colours without a touchscreen option. Wireless connectivity uses 802.11ac Wi-Fi 5 and Bluetooth 4.0, which cap throughput and peripheral support at those standard generations. The all-in-one chassis fixes the screen size and prevents display upgrades or external GPU attachment. Memory is soldered LPDDR3, so capacity cannot be increased after purchase.
Capacity and headroom for daily workloads
Eight gigabytes of 1867MHz LPDDR3 handles typical multitasking and creative apps, but heavier video editing or virtual machines will exhaust the available RAM. The 1TB 5400rpm hard drive offers ample space for large libraries, yet its rotational speed limits boot and load times compared with solid-state storage. Turbo Boost up to 3.6GHz provides short bursts of extra compute for demanding tasks.
