Xiaomi has introduced the Mi Box 4S MAX in China, where it sells for CNY 499 (~US$75). Listed as supporting 8K content, the Mi Box 4S MAX has HDMI 2.1 connectivity, relies on an Amlogic S905X3 chipset and has 4 GB of RAM.

Xiaomi has launched the Mi Box 4S MAX in China, where it is already orderable on JD.com. As marketing images suggest, the Mi Box 4S MAX is a streaming box that can bring Smart TV features to a monitor, projector or a TV. For reference, the Mi Box 4S MAX measures 95 x 95 mm x 16 mm, but it cannot be mounted to a TV like competing streaming sticks can, such as those sold by Amazon and Roku.

According to Xiaomi, the Mi Box 4S supports HDMI 2.1 connectivity for up to 8K streaming. However, it remains to be seen whether the Amlogic S905X3 SoC can decode 8K content using the Amlogic Video Engine (AVE). If not, the Mi Box 4S MAX peaks at 4K/60 FPS decoding. Incidentally, the streaming box has 4 GB of RAM and 64 GB of storage for running MIUI for TV. Unsurprisingly, Xiaomi has also included a remote control that supports voice commands, mirroring the functionality of Amazon's Fire TV products.

Moreover, Xiaomi has equipped the Mi Box 4S MAX with a dual-band WiFi modem, plus a USB Type-A port and an AV connection. Allegedly, the streaming box supports Dolby Atmos and DTS audio too, but other features like MEMC technology are absent. Currently, the Mi Box 4S MAX is available in China for CNY 499 (~US$75); Xiaomi has not confirmed whether it plans to launch the Mi Box 4S MAX globally yet, though.
