Broadwell-ULX 4-6W and the upper Broadwell-ULT 25W, other models unchanged TDP. The unchanged 15W for ULT models gives me hope that we will see a bigger performance improvement. Haswell-ULT couldn't really improve its CPU because of the lowered TDP. I wonder if Broadwell-K comes with DDR4 given that Broadwell-H seems to use DDR4.
