I can't even find an AMD tablet/Laptop that I'd even consider buying.
For a Tablet it'd basically have to be nigh on close to my Surface 3 Pro's build quality, with at least a 1080p screen.
And same with a Laptop being close to my Ultrabook in terms of build and screen resolution.
I just bought my grandad a Braswell N3150 itx all in one to replace his g540.
It's a quad core 2.1ghz with hd 12 eu's. Now this was much like Amd's am1 attempt at a tablet soc but the most impressive thing about it is the 10-12w power consumption even with 2 slots full of ddr3l memory.
I would gladly use one of these as a htpc, but there was a problem with getting support for dts hd audio master.
Like you said where is Carrizo L and the scaled down puma+ ?
