The SoC (Amlogic S905X5M variant) in 6 nm delivers improved GPU performance over previous generations, which helps with rendering UI, animations, and playback performance.
In reviews, the system is reported to feel fluid and responsive when navigating apps, menus, and streaming in 4K.
Some internal memory and RAM will be consumed by the OS, so the usable free memory is less than 2 GB / 32 GB.
Since it has only a single USB 2.0 port, expansion (e.g. external storage, peripherals) is limited in bandwidth.
It supports widely used video codecs and HDR formats; however, compatibility with specific streaming services, apps, or DRM levels may depend on region or updates.
The remote is Bluetooth and includes voice search / Google Assistant functionality.
