I would like to see a comparison with AMD's top Bristol Ridge vs Intels top Skylake, rather than using a 1 model down from AMD and 2 models down from Intel. It would also be nice to see the AMD vs a Broadwell with the eDRAM just for kicks.
My only issues is the single stick of ram. I wonder if it has another free slot.
That's the expected HP incompetence.
I'd be surprised if the Bristol Ridge boards weren't all dual channel with 2 slots, but if I'm wrong I'm sure HP would be the one to use single slot boards.
The reason some carizzo laptops were only single channel was because OEMs cheaped out and used mullins boards.
