Why there are no windows tablets on AMD cpu?
AMD tried to convince OEMs with their Temash APUs (4x 1GHz + 1.5GHz Boost in Turbo-Dock) - didnt worked out.
A Tablet should not use more than 7-8W - the lowest Ryzen 3 2200U has 12W
if you wish i can try to underclock my Ryzen 5 2500U to 7W and give some benchmarks - what i can say is that at 5W he clocks itself down to 400MHz... - that would not be good for Win-Tablets...
What about the embedded processers?
