S905X2

The S905X2 is a 64-bit system-on-chip (SoC) developed by Amlogic for media streaming devices and smart set-top boxes. It is positioned as a mid-range successor to the S905X and is widely used in Android TV boxes and other streaming devices. The chip integrates a quad-core ARM Cortex-A53 CPU, typically running up to about 1.9 GHz, and a Mali graphics unit, with the exact GPU variant varying by revision.

The S905X2 provides hardware-accelerated video decoding for HEVC (H.265) and VP9 codecs, enabling 4K video playback on supported displays. The device output commonly includes HDMI 2.0a with 4Kp60 support and HDR formats on capable boards. The SoC also includes a video processing engine and display pipelines designed for mainstream streaming tasks.

Memory and peripheral support vary by board and firmware, but the SoC is designed to work with common DRAM configurations used in consumer media devices, along with typical connectivity such as Gigabit Ethernet and USB 3.0. The exact feature set—clock speeds, GPU model, memory interfaces, and I/O options—depends on the specific revision and vendor implementation.

Since its introduction in the late 2010s, the S905X2 has seen widespread use in budget to mid-range Android TV boxes and media players, offering efficient multimedia performance and broad codec compatibility for streaming applications.
