Intel Demos 14nm Broadwell: Up to 30% Lower Power than Haswell
 

Intel just demonstrated 14nm Broadwell ULT (Y-series) silicon, normalized for performance against 22nm Haswell ULT (Y-series) silicon running a multithreaded Cinebench test. Intel was monitoring SoC power during the benchmark and demonstrated a ~30% reduction in power, at the same performance level.

The other reveal? Broadwell ULT, albeit still a two-die, single chip MCM, is physically smaller than Haswell ULT. A physical size reduction is necessary to get Broadwell into fanless tablet designs that can have competitive battery capacities to ARM based designs.
