Amazon completely revamped its Kindle family in October when it debuted the entirely new Colorsoft ereader along with updated generations of the other three existing models: the standard Kindle, the Paperwhite and the Scribe E Ink tablet. The new Paperwhite has a slightly larger screen, a bigger battery and a more powerful processor that Amazon combined with E Ink tech to make page turns faster. This Paperwhite again comes in a Signature Edition, which adds wireless charging, an auto-adjusting front light and extra storage — all for $200, which is $10 more than the previous Signature Edition.
The standard Kindle also got a $10 price bump, leaving the same $90 gap between Amazon’s cheapest model and the Signature Edition. I tested both to see whether the price difference between the two is worth it. The higher-end model is certainly posh, but the base model handles ereader basics well. Is the deluxe treatment that much better?

Processor, capacity and other hardware features
The company is calling the Paperwhite (Signature and standard) the “fastest Kindle ever” thanks to a new dual-core processor and an oxide thin-film transistor layer that enables quicker switching of the text and graphics on the page. That layer is also more transparent than the previous tech, so the on-page clarity has increased as well.
As for storage, the Paperwhite Signature gets 32GB, double that of the regular Paperwhite, which is the same treatment as the prior generations for both. They have a couple additional backlights this time: ten standard LEDs and nine warm ones for a total of 19.
