The Kindle Oasis is getting all the attention today, but it's not the only Amazon hardware leak. There's also the upcoming basic Kindle "Woody", and now new benchmarks have leaked which point to a new Fire tablet.
According to the GFX database, the new Fire tablet is an update or replacement for the Fire HD8. It has the same screen resolution (1280 x 800), but features a slightly faster CPU than the model launched last September.
The new tablet runs Amazon's version of Android 5.1.1 on a quad-core 1.3Ghz MediaTek MT8163 CPU with a Mali-T720, 1.3GB RAM, and 4.5GB internal storage. It has a Wifi, Bluetooth, a bevy of sensors, and two cameras (VGA and 1.8MP).
Those are weaker cameras than can be found on the current model, so I can't recommend that you upgrade. In fact, this techie would suggest getting the older model. The CPU isn't that much weaker, and what with the better cameras I think last year's Fire HD 8 is the better buy.
