Features

The AMD Radeon 620 has 2 supported features recorded and 1 feature explicitly listed as not supported outside the media engine. A feature that no source mentions is shown as not listed, never as unsupported.

Display features

Supported: AMD FreeSync

Support for AMD's variable refresh rate technology, which syncs compatible displays to the GPU to reduce tearing and stutter.

Not supported (1)

Explicitly not supported: HDMI 4K output

What it is: The vendor states the GPU can drive a 4K display over HDMI.

Not listed (6)

No source Feex holds states whether the AMD Radeon 620 supports Stereoscopic 3D, 10-bit color output, VR ready, 8K display output, HDR output and 12-bit color output. That is silence, not a statement that they are unsupported.

The AMD Radeon 620 supports AMD FreeSync under Display features. HDMI 4K output is explicitly listed as not supported.

Software and drivers

Supported: Radeon Chill

AMD driver feature that lowers frame rate when there is little on-screen action to cut power use and heat.

Not listed (7)

No source Feex holds states whether the AMD Radeon 620 supports Enhanced Sync, Image sharpening, Radeon Anti-Lag, Radeon Boost, Radeon Super Resolution, Radeon ReLive and AMD Fluid Motion Frames. That is silence, not a statement that they are unsupported.

The AMD Radeon 620 supports Radeon Chill under Software and drivers.
