Amazon Fire TV Cube
Score: 81/100
Xiaomi TV Stick 4K 2nd Gen Black
Score: 80/100Rankings
The Amazon Fire TV Cube is a hands-free 4K streaming box with a powerful octa-core CPU and full HDR/Dolby Atmos support. Its bulkier form factor, lack of gaming-focused features and occasional ad-laden UI are trade-offs. Ideal for Alexa-centric homes that value HDMI switching and high-speed Wi-Fi 6E.
Xiaomi TV Stick 4K (2nd Gen) is a compact dongle with Wi-Fi 6, a powerful 2.5 GHz CPU and Dolby Vision/Atmos support, running Google TV. It lacks Ethernet and AI upscaling, which may affect network stability and upscaling quality. Great for portable, budget-friendly 4K streaming on the go.

Professional reviewers praise the Fire TV Cube for its powerful octa-core CPU, comprehensive HDR and Dolby Atmos support, and the unique hands-free Alexa with HDMI input that simplifies switching between streaming and live sources. However, they note the mediocre SDR upscaling, lack of gaming-focused features like VRR/ALLM, and a bulkier form factor compared to slimmer competitors.
Everyday users consistently highlight the convenience of hands-free Alexa, rapid app launches, and excellent 4K/Dolby Vision picture quality, while expressing frustration over intrusive ads, occasional voice-recognition hiccups, and sub-par upscaling of non-4K content.

“absolutely crazy smooth”

Everyday users consistently commend the device for lag-free 4K streaming, portable form factor, and responsive UI, with few complaints aside from the missing AI super-resolution capability.
