RockTek G2 Next

A Certified 4K Android TV Box Built for Streaming

The RockTek G2 Next is a 4K Android TV box that turns any HDMI-equipped television into a full smart TV. It runs Google-certified Android TV 14, so your apps, Google account and voice search work the way they should.

Certification matters. The box carries Widevine L1, PlayReady SL3000 and HDCP keys, which lets it play HD and 4K streams that many uncertified boxes cannot. That makes it a Netflix certified Android TV box you can rely on for Netflix, YouTube, Prime Video and Disney+ in 4K, with HBO Max also supported.

Key Features and Benefits

• Amlogic S905X5M-J chipset: a 6nm quad-core Cortex-A55 processor running at up to 2.5 GHz for quick menus and app launches.
• Mali-G310 V2 graphics: a much stronger GPU than the one in the original G2, for smoother interface animation and video playback.
• 4K HDR with Dolby Vision: a proper 4K HDR streaming box for compatible TVs and content.
• Dolby Atmos: a Dolby Atmos TV box that passes immersive audio to your soundbar or AV receiver.
• Wi-Fi 6 and Gigabit Ethernet: stable throughput whether you connect wirelessly or by cable.
• HDMI 2.1b output: up to 4K at 75 Hz on supported displays.
• Bluetooth 5.2: pairs with a Bluetooth 5.2 voice remote, headphones and other accessories.

Smooth Performance From the Amlogic S905X5M

The Amlogic S905X5M-J steps up from the S905X4-K in the original G2. Its four Cortex-A55 cores at up to 2.5 GHz handle the everyday work of a streaming box: app switching, browsing your library and decoding high-bitrate video.

The Mali-G310 V2 GPU is said to double graphics performance over the previous generation. In practice you should see a more fluid interface and better headroom for lighter Android games. It is a media box first, not a gaming console, so set your expectations accordingly.

The platform is also aimed at modern codecs, which is why this box suits you as an AV1 streaming media player for services moving to efficient 4K delivery.

Cinema-Grade Picture and Sound

Connect the G2 Next to a 4K HDR television and you get HDR playback with Dolby Vision on supported apps and screens. Dolby Atmos support means films and series with Atmos tracks can reach a compatible soundbar or home theatre system.

An SPDIF digital audio output is also included, which helps if you run older receivers. We found no DTS:X information for this model, so do not buy it for that format.

The HDMI 2.1b output makes this a capable HDMI 2.1 TV box for current televisions. Check that your TV's HDMI input supports the mode you want.

Fast, Stable Connectivity

Wi-Fi 6 gives you better performance in busy homes with many connected devices, making this a practical Wi-Fi 6 TV box for 4K streams. If your TV sits near your router, the wired option is better still.

As a Google TV box with Gigabit Ethernet, the G2 Next lets you plug in a cable for the most consistent connection when streaming high-bitrate 4K. Bluetooth 5.2 covers wireless headphones, controllers and remotes.

Memory, Storage and Ports

Your listing data shows 4 GB of RAM and 64 GB of eMMC 5.1 storage, with a microSD reader for adding more space for apps and media. Some sources list a 2 GB variant, so confirm the exact configuration before you buy.

• HDMI 2.1b: video and audio to your TV.
• Ethernet: one Gigabit RJ45 port.
• USB 2.0: one Type-A port for storage or accessories.
• USB-C: used for power and data. Port count varies between sources, so check the variant.
• SPDIF: digital audio output.
• microSD: expandable storage.

Some regional variants also offer a DVB-S2 or DVB-T2 tuner for satellite or terrestrial TV. Check the exact version if you want it.

Remote Control Options

For navigation, the G2 Next pairs with a Google TV box with voice remote, so you can search by speaking. Voice remotes use Bluetooth 5.2 for a responsive link without line of sight.

If you prefer physical keys for channel entry, look for a Google TV box with number-button remote option. Remote contents can differ by bundle, so check the product details for your version.

Who Should Buy the RockTek G2 Next

• Home theatre fans: Dolby Vision, Dolby Atmos and HDMI 2.1b suit a TV and soundbar setup.
• Cord-cutters: certified 4K apps replace a cable box with one compact streamer.
• Satellite and terrestrial viewers: the optional tuner version suits live TV.
• Upgraders: if you own the original G2 or an ageing smart TV, the newer chip, GPU and Wi-Fi 6 are a clear step up.

You pay extra for certification and support compared with generic S905X5M boxes. Those boxes can cost less, but they often lack the full licensing for 4K streaming.
