Buried beneath that sleek body is a new hexa-core processor which has enabled Amazon to offer local voice control, with on-device processing. That has been combined with far-field microphones that, hopefully, will help the system hear you in busy rooms. Amazon claims that the extra speed and processing power means that the Fire TV Cube is more than four times faster than the previous edition.
In terms of picture quality, the original Fire TV Cube supported Dolby Vision and HDR, but this new model also gets HDR10+. As usual, you get HDMI CEC to run all of your home entertainment devices, and Amazon promises it's made it faster than gear from other companies.
In a demo at Amazon's noisy event, the Fire TV Cube was fast, although it did struggle to pick up my voice when I spoke at my normal volume. What was obvious was the speed of the processing, without the lag you would expect from a voice-controlled system.
It's sometimes hard to see where something like the Fire TV cube fits into Amazon's complicated ecosystem of connected home products. Company representatives said that it isn't intended as a replacement for an Echo, assuming you've paired it with a Fire TV stick, in your living room.
The Fire TV Cube is available to pre-order today with an infrared extender cable and an Ethernet adapter for shipping in early October for $119.99 in the US, Canada $149.99, UK for £109.99.
