The version with product ID B09BZWZS6S corresponds to the third generation of Amazon's Fire TV Cube, not the second. This third generation was released from October 2022 and features an octa-core processor, Wi-Fi 6e, multiple HDMI ports and other improvements over the second generation.

The second generation, on the other hand, has a hexa-core processor, 2 GB of RAM, 16 GB of internal storage, support for Dolby Vision and HDR10+, and weighs about 465 grams.

Thus, the model with 16 GB and Fire OS shown is the third generation, not the second.
