Product Details
Amazon Fire TV Cube (3rd Generation)
The ultimate hands-free 4K streaming platform — engineered for speed, premium HDR playback and centralized entertainment control
The Fire TV Cube (3rd Gen) is Amazon’s fastest Fire TV device to date. An advanced octa-core processor and Wi-Fi 6E deliver instant app launches, fluid navigation and reliable streaming. Watch native 4K Dolby Vision content, enjoy Dolby Atmos sound, and upscale HD sources with Super Resolution to near-4K quality. Built-in Alexa provides hands-free voice control for entertainment and smart-home orchestration, while HDMI device control, Ethernet and USB connectivity make the Cube the technical anchor of a modern AV system.
Performance-First Design for 4K Streaming & System Control
Architected around a high-performance octa-core ARM SoC and modern connectivity, the Fire TV Cube (3rd Gen) provides a platform capable of real-time upscaling, premium HDR rendering and simultaneous AV control. Whether you stream Dolby Vision Dolby Atmos titles, ingest HDMI sources via the on-board HDMI input, or manage legacy IR devices through the included IR blaster, the Cube centralizes audio-visual and smart home workflows into a low-latency, voice-activated experience.
Supported streaming codecs, HDR profiles and Dolby features are contingent on app support and the attached TV/AV receiver configuration. Network performance may vary by environment and ISP.
Core Capabilities
High-Throughput Compute & UI Responsiveness
An octa-core ARM processor provides ample headroom for app concurrency, UI animation and real-time video processing. Expect minimal load times, consistent menu responsiveness and fluid navigation across the Fire TV experience.
4K HDR & Intelligent Upscaling
Native 4K output with support for Dolby Vision, HDR10, HDR10+ and HLG. Super Resolution upscales HD sources, applying spatial and temporal algorithms to improve perceived detail and edge fidelity, delivering a noticeably sharper image on 4K displays.
Immersive Audio & Device Control
Dolby Atmos passthrough for compatible AV receivers and immersive soundtracks. Onboard audio and an integrated IR blaster enable hands-free control of a connected entertainment stack; HDMI passthrough simplifies source routing.
Modern, Resilient Networking
Wi-Fi 6E unlocks a less congested 6 GHz band to reduce interference and improve throughput for 4K streams. A dedicated Ethernet port supports hardwired network deployments for deterministic performance.
Flexible I/O for AV Integration
HDMI In accepts external devices (consoles, set-top boxes), while HDMI Out outputs to your display. USB-A supports accessories and external storage; IR extender compatibility and an included remote provide broad device interoperability.
Built-in Alexa & Hands-Free UX
Alexa is integrated for hands-free content search, playback control, smart-home commands and more. The Cube’s microphone array and built-in speaker enable voice interactions without a secondary device.
