"8th generation" is a Marketing term which can vary by sales region.
In the USA, there are two (2) "8th generation" Kindle 'e-reader' devices (other than Kindle Fire e-readers).
Please use the first six characters of your device's serial number and this table:

to learn what the model specific nickname is that you (and we) need to know when discussing technical features.
Note:
There are also "8th generation" Kindle Fire (color) devices, those run a Google/Linux os (a.k.a: Android).
This is the forum for the grayscale Kindle devices, which run an Amazon/Linux os (no specific name).
So in the case of your specific question, it is important that we know the specific model (by nickname) you are asking about.
