If true, it would be a nice improvement over the Broadcom 1250/1480,
but nowhere near a factor of 10. Why would you be surprised that a
design optimized for low power is much better per watt than ones which
view high power as a necessary evil?
Interestingly enough, the founders of PA Semi overlap with the
founders of Sibyte, which was purchased by Broadcom.
