ODROID-XU's ARM big.LITTLE A7 + A15 Octa-Core

On the note of not needing graphics. Does anyone know of any small board with dual GigE ports that doesn't have a GPU? For this, I don't mind using an ARM SoC as long as any of the major distros support it well out of the box (ie. can saturate the 1 GbE link and has hardware offloading for packets).
I tried looking into the Intel Rangeley Atoms which are based on Silvermont, has integrated GbE NICs and no GPU but I've only seen large network appliances with 8 or more GigE ports. Those, of course, aren't cheap. Otherwise, I'm back to my question of fairly inexpensive Bay Trail based micro boards.

Anandtech ran some benchmarks not too long ago and haswell and the Apple A7 seemed to be the most efficient followed by the newer snapdragon. The A15 is pretty damn inefficient from everything i've read, but is a necessary step to higher ipc.
OTOH, big.LITTLE, while seeming hacky, seems to work pretty well from following lwn's coverage.
My preference, however, is the way qualcomm went about things.

Plus he takes practical Intel ad copy and makes an article out of it; e.g., all the pre-launch Haswell hype.

They admit sunspider is pretty worthless since everyone optimizes for it so I don't know why they still use it.
I've long heard the claim that AT shills for Intel but never seen any evidence.
The thing is, anyone is welcome to refute his claim with their own results.

If not, then it's not factual and therefore FUD and I won't have a word of it.
I have come across chips before where you cannot power-gate one part off without that part's driver.
