Because paper didn't start in 2013? Have you missed what was used? Sandy Bridge. Not Ivy Bridge nor Haswell.
Hell, they have Atom x450. Released in 2010.
Your point never existed, because you ignored age of used Intel's hardware and then you wonder why they have "old" ARM. Because that paper was started in 2010! You cannot use unreleased stuff you don't have access to!

2. Why use ancient A8, and, worse, a Beagle board? For a 2013 paper you'd expect at least 2012 hardware.
