Intel gave bribe money to Samsung for not choosing AMD APUs . AMDs Jaguar APUs is clearly superior in performance and power efficiency compared to any production Intel processor. This is injustice to the consumers.
Perfomance? Yes, AMD APU is way better.
Power? Definitely not compared to this particular atom.
If you knew anything about the atom there using, you'll know that it design for mainly Smart Phones. Something the AMD (last i checked) is not targeting.

So using something that specifically design for a phone vs something that design for a beefier power tablet, the power requirements are not going to be the same.
As for why Samsung chose the Atom over the APU, probably battery life or it may have something to do with that this atom works Android while the Jaguar APU (as far as I know) is only targeted at Windows X86 tablets. Thus, for Samsung, would not make any sense for them run a cpu that doesn't work for there needs.
Now if someone actually finds some solid info that the AMD Jaguar is also meant to be used with the Andriod OS, then I'll removed the part above about "Jaguar APU is only targeted at Windows X86 tablets". Although this is the info i'm finding ATM.
