On the processor side, e-readers are not powerful machines and the new Oasis doesn’t do much to change that. Like its predecessor, it uses a 1Ghz processor, although the 7-inch Oasis's is an updated chip: an NXP i.MX7D vs a the original's FSL 6 SL Cortex-A9. The new chip lets the 7-inch Oasis run faster; side-by-side with the 2016 model, the new kid flips pages quicker. (Menus, keypresses, etc, seem to fire with the same speed.) Its light sensor, which adjusts the screen’s brightness based on the ambient illumination, though, is so fast it’s almost annoying. If you, for example, roll over in bed to grab a glass of water and subject the Oasis to a brighter cone of lamplight, the 7-inch Oasis will lighten its screen almost instantaneously. If dials it down when you roll back over, though.
