Xiaomi TV Box S (3rd Gen) vs Fire TV Stick 4K Max: Which Is Better in the UK?

UPDATED AUGUST 2026 · UK COMPARISON

Two mainstream 4K streamers with very different strengths: Xiaomi gives you Google TV, 32GB storage and a USB port; Amazon gives you Fire TV, Wi-Fi 6E and a compact stick.

Research status: this comparison is based on current Xiaomi UK and Amazon specifications. ViewHarbour has not yet physically tested both exact retail units.

Quick verdict

Choose the Xiaomi TV Box S (3rd Gen) if 32GB storage, Google TV and a full-size USB port matter most. Choose the Fire TV Stick 4K Max (2nd Gen) if you already prefer Alexa and Fire TV, want Wi-Fi 6E and value the hidden stick form factor.

1. Storage: Xiaomi has the clearer advantage

Xiaomi specifies 32GB of internal storage, while Amazon lists 16GB for the Fire TV Stick 4K Max (2nd Gen). Neither figure is fully available to the user after system files and updates, but Xiaomi starts with twice the nominal capacity.

That matters if you install a larger app library or simply want more breathing room for updates and cached data. It is one of the main reasons the Xiaomi box remains our value pick.

2. Software: Google TV vs Fire TV

This is less about “better” software and more about which ecosystem you want. Xiaomi runs Google TV, with Google Play, Google Cast and Google Assistant integration. Amazon uses Fire TV with Alexa and the Amazon Appstore.

If your household already uses Echo speakers and Alexa heavily, Fire TV can feel more natural. If you prefer Google TV recommendations, Google Cast and the broader Google ecosystem, Xiaomi is the more obvious fit.

3. Wireless networking: Fire TV wins on the headline spec

Amazon lists Wi-Fi 6E on the Fire TV Stick 4K Max, including the 6GHz band where compatible routers and local conditions allow. Xiaomi uses dual-band Wi-Fi 6 on 2.4GHz and 5GHz.

That gives Fire TV the stronger wireless specification. In practice, streaming reliability still depends on your router, distance, interference and broadband connection, so Wi-Fi 6E alone is not a reason to replace a stable setup.

4. Ports and placement: box vs stick

Xiaomi is a small box and includes HDMI 2.1 plus a full-size USB 2.0 port. Amazon’s 4K Max is designed to disappear behind the television, which is tidier but gives you fewer obvious physical connections.

Neither device has built-in Ethernet. Amazon documents wired networking via an external adapter; Xiaomi’s own FAQ says the Box S (3rd Gen) does not support an RJ45 LAN port.

5. Picture and sound

Both are designed for mainstream 4K HDR streaming and both support Dolby Vision and HDR10+. Amazon also lists HDR10 and HLG on the 4K Max. Xiaomi’s current product material highlights Dolby Vision, HDR10+, Dolby Atmos/Dolby Audio and DTS:X support.

Actual HDR and audio output still depends on your TV, sound system, streaming service and the specific programme.

Which should you buy?

Choose Xiaomi for 32GB storage, Google TV and the convenience of a full-size USB port.

Choose Fire TV 4K Max for Wi-Fi 6E, Alexa integration and the smallest hidden setup.

Our current default: Xiaomi for value-focused buyers who do not specifically prefer the Amazon ecosystem.
