Remember that new Nook Android tablet that my sources said would be launched in October but B&N said would not be launched this year? B&N might not be planning to ship the tablet this year, but they do have it under development and it just showed up on a benchmark website.
According to GFX Bench the new Nook device, which I am calling the Nook X, will have the model number BNTV800 and run Android 4.2.2 on an Nvidia Tegra 4 chip.
There's very little other information available, but I can tell you that the CPU speed registered at 1.8GHz. I also know that the screen resolution is 1620 x 1080, but I can't tell you about the screen size.
That's not a standard resolution, so there's really no way tell how big B&N's new tablet really is. While it is possible that B&N might have a tablet with a nominal screen size of 1620 x 1200 and decided to reserve the missing 192 pixels for onscreen buttons, I would not bet on it.
And I wouldn't bother trying to guess the screen size from the model number; one has nothing to do with the other. The new Nook Glow, for example, has a model number of BNVR500-A, even though it has a 6" screen. in fact, the only relevant detail I can deduce from the model number is that this is a tablet (bnTv800, the T is for tablet).
The Nook X has yet to be confirmed by B&N but past leaks have given us a few hints. I know that B&N has commissioned a for Dummies book, and I know that a product listing for a BT keyboard showed up on the B&N website. I still haven't managed to get my hands on either item but they tended to support B&N's past statements that they had a new tablet in the works.
Update: That B&N branded BT keyboard is now available on the B&N website.
This new model hasn't shown up on the FCC website yet, and I have not found it on any other resource website like Google's list of supported Android devices. But I am sure it will show up in short order.
