The 2023 Fire TV Stick 4K Max introduces Fire OS 8, which is built on Android 11, delivering enhanced system performance, security, and app support compared to the 2021 model that operates on Fire OS 7.

This latest model significantly upgrades the user experience with faster app launches and improved navigation, making it a compelling choice for new buyers.

Priced at $59.99, often available for $44.99, the 2023 model offers tangible upgrades that justify the investment for those looking to enhance their streaming experience.

With a doubled storage capacity of 16GB, the 2023 version reduces app-loading lag and allows users to install more apps without performance issues.

Bluetooth capabilities have also been enhanced, featuring Bluetooth 5.2 and Low Energy support, compared to Bluetooth 5.0 in the previous model.

The 2023 model supports Wi-Fi 6E, which provides tripled bandwidth potential, crucial for buffer-free 4K streaming in congested networks, while the 2021 model only supports Wi-Fi 6.

Although Wi-Fi 6E is not essential for streaming at present, it can be advantageous in environments with many competing devices.

The new model also enhances the audio-visual experience with improved HDR refinement and support for Dolby TrueHD, offering uncompressed 7.1 surround sound.

While both models support HDR and Dolby Vision, the 2023 version adds Dolby TrueHD with Atmos for superior audio quality compared to the older model's Dolby Digital 5.1.

Both the 2023 and 2021 models are compatible with any HDMI-equipped display, and the newer version includes enhanced upscaling for non-4K TVs.

In terms of resale value, the 2023 model retains approximately 70% after a year, significantly higher than the 50% retention for the 2021 edition.

Current owners of the 2021 model may not feel an immediate need to upgrade unless they specifically desire the advanced 7.1 Atmos audio capabilities, as the older model still effectively handles 4K/HDR content.
