DELL OptiPlex SFF i5-6500 3.2GHz 16GB DDR4 1TB SSD Radeon RX 550 4GB

Compact gaming desktop for everyday play

This Dell OptiPlex small-form-factor system pairs a 3.2 GHz Intel Core i5-6500 with 16 GB of DDR4 memory and a 1 TB SSD. The AMD Radeon RX 550 4 GB graphics card drives two DisplayPort outputs and one HDMI port. Windows 10 Pro is pre-installed, and a wired keyboard and mouse are included.

Sustained-load behaviour with 65 W processor

The i5-6500 runs at a 3.20 GHz base frequency and can reach 3.60 GHz on shorter bursts, so frame rates stay steadier during long sessions than on lower-power chips. Sixteen gigabytes of DDR4 keeps background tasks from forcing the SSD into heavy swap activity. The RX 550 delivers consistent entry-level 1080p performance without the clock throttling seen on integrated graphics.

Thermals, noise and power in normal use

The slim chassis uses Dell's directed-airflow design to move heat from the 65 W CPU and the RX 550 through a single blower-style fan. Acoustic output stays at typical office levels during browser work or video playback and rises moderately under gaming load. Total system draw remains well within the range of the internal power supply, so no external adapter is required.
