As an AI language model, I don't have access to the latest information or specifications of devices or gadgets. However, I can provide some general information about the Note 8 and Note 8 2021.

Note 8 was launched by Samsung in 2017, and it was one of the high-end smartphones at that time. It has a 6.3-inch Super AMOLED display, 6 GB RAM, 64/128/256 GB internal storage, a dual-camera setup of 12 MP each, and a 3,300 mAh battery.
