I think the A53 are at 1.4 and not 1.8 GHz, as 1.8 GHz operation requires significant over-voltage.
With this said, this could make a nice tablet for home usage. Two A72 cores mean that a browser is expected to be at least usable, and being rugged implies that you care less about the risk of it falling from the sofa on the floor, or kids throwing it at each other’s face. I expect it will not be cheap though.
The RK3399 would also most likely burn a hole in the plastic housing, as at full load, it gets scorching hot.
On top of that, this tablet is likely to have very poor battery life, as it’s not a power efficient chip.
A normal heatpipe seems to address the ‘scorcing hot’ issue in the ASUS c101pa quite adequately. Whether that would be an option for this entry-level tablet is yet to be seen.
given the tablet’s thickness, I think that even a full-width, full-length thermal plate to spread the heat into the bottom’s surface would work reasonably well.
Crap cameras and outdated Android. Those chinese 2MP cameras are especially bad.
