DELL OptiPlex 990 SFF All-in-One 22" i5-2400 16GB 512GB SSD

Dell OptiPlex 990 SFF All-in-One 22

This Dell OptiPlex 990 SFF All-in-One combines a 22-inch 1920 x 1080 monitor with a compact desktop base. It is powered by a 2nd Gen Intel Core i5-2400 processor running at 3.10 GHz with four cores and four threads. The system includes 16 GB of DDR3 memory and a 512 GB solid-state drive. Windows 10 Pro 64-bit is pre-installed, and a USB keyboard and mouse are supplied.

Sustained load behaviour

The i5-2400 can reach 3.60 GHz via Turbo Boost when thermal headroom allows, giving extra speed for demanding tasks. The small form factor chassis and integrated all-in-one design limit airflow compared to larger towers, so clock speeds may settle lower during extended heavy workloads. The 512 GB SSD maintains consistent read and write performance without the latency spikes of mechanical drives. DDR3 memory bandwidth matches the platform capabilities of the Intel Q67 chipset.

Compatibility checklist

Verify that your workspace can accommodate the 22-inch display and its AIO base stand. The system provides DVI-D and VGA video inputs for external sources, plus USB 2.0 upstream and downstream ports for peripheral connectivity. A USB Wi-Fi adapter handles wireless networking. The internal 2.5-inch drive bay and DDR3 slots determine future storage or memory upgrades. DVD-RW media access is available via the integrated optical drive.
