There are more detailed specs on 4pda.ru. From the looks of it, it's just larger display, and otherwise the exact same soc as InkPad 3 -

This is not really good news performance wise, especially compared to monstrous android octacores for the same price tag. The only thing going for this soc is low power usage. Further, the larger screen you have, the more pixels you have to render from a vector. That's CPU intensive but also more bits to serially shuffle on the EPDC SPI. All said, it will be comparatively (~1.5x or worse) slower than the already slow InkPad 3.
