Xiaomi TV Stick 4K 2nd Gen Black
Score: 80/100Rankings

The Xiaomi TV Stick 4K (2nd Gen) is a pocket-sized streaming dongle delivering 4K HDR with Dolby Atmos and Wi-Fi 6. Its trade-offs are limited internal storage and the absence of a wired Ethernet connection. It best serves travelers and secondary-TV setups where size and cost are paramount.

The RockTek GX1 UHD Streamer offers a compact Google TV experience with Dolby Vision, HDR10+, and Dolby Atmos, backed by a Realtek processor, 4 GB RAM and HDMI 2.1. Its drawbacks include a non-Gigabit Ethernet port, limited USB-2.0 speeds, and potential heat issues. Best suited for users who value a small form-factor and premium video/audio without needing ultra-high-bitrate wired streaming.

Products in the top-left offer the best value (high score, low price).

Professional reviewers commend the GX1 for its striking Dolby Vision and HDR10+ performance at 2160p60, smooth AV1 playback, and the polished Google TV 12 experience. However, they point out the 100 Mbps Ethernet as a bottleneck for high-bitrate local streaming and note the absence of VC-1 support and limited ventilation as drawbacks for power users.
Everyday users overwhelmingly praise the GX1's video and audio quality, compact size, and responsive interface, often calling it a top-line product that outshines competitors. The most common complaints revolve around screen-resize issues on certain LCD TVs and the lack of Gigabit Ethernet for heavy NAS-based media consumption.

“topline product with great RTD1325 performance.”

“"Ok" rating due to this.”

“pretty much the same spec as we usually get on larger TV boxes”




Professional reviewers praise the Xiaomi TV Stick 4K (2nd Gen) for delivering performance on par with much larger TV boxes, highlighting its smooth interface and substantial CPU/GPU improvements, while noting the lack of AI upscaling as the main drawback.
Everyday users consistently commend the device for its lag-free 4K streaming, portable form factor, and responsive UI, with few complaints aside from the missing AI super-resolution capability.
