So you're basically stuck with the number of cores of a single socket per 1U, seems like a waste of space and possibly power usage when 2 cores are utilized per 10GE port (in this video). Doesn't seem to scale well now that 100GE is getting more common, so 2 100GE ports per 1U? Depending on where this device would be used the recent 32port 100Ge 1U switches seems to be more interesting, small fib, but with the correct protocol support it could fit a lot of use cases, especially with something like sir[1].
