After trying out the new 4K Fire TV Stick for several hours and testing both the audio and the new HDR and 4K functionalities, we can conclude that the purchase or change to the new model was really worth it.
The stick is not only noticeably faster in response time as far as the menu is concerned than its predecessor, but even faster than the Fire TV box, which had at least 512 MB more RAM. Here, the entire software seems to have been completely put to the test in order to provide a really solid performance.
For streaming 4K content, our real-time online counter has never shown more than 15 Mbps. Which is probably also due to a revised compression method and the cache of the Fire TV sticks.
The comparison in terms of speed, sound and picture quality between the Sony 4K HDR Smart TV used by us and the stick has clearly shown why Amazon has thought of the app rather as a last resort. Because despite a comparably strong processor and memory equipment in our TV set this could never even keep up with the performance of the stick. On the new stick, everything runs really nice crisp and fast, and selected videos start almost immediately. And that’s why the switch is worthwhile even for owners of Smart TV’s.
One reason for the different performance is also that the CPU and the available memory in a Smart TV are not only available for the Prime Video App, but they have to share the performance with the entire image optimizers in the background mostly running. This is just different with the stick, because it uses the available computing power primarily for its core competence.
For the price of currently just under 60 € you get a really neat streaming stick, which also leaves little to be desired because of the available apps.
The 4K Fire TV is currently offered as a variant with and without Alexa Dot (third generation). Optionally, in case of poor WLAN also an additional module can be plugged in, which makes the connection possible also via Ethernet cable.
