Besides FLOP/Watt what's also very interesting here is the FLOP/Byte ratio (memory bandwidth). It has kept the same balance as K computer, i.e. is geared at scientific workloads and not just benchmarks (duh, just worth pointing out here as it makes this machine quite special especially compared to Xeon based clusters - Intel IMO has dropped the ball on bandwidth since the last 5 years or so).
