It looks like Intel will be showing off its 14nm processors, codenames Broadwell, in a couple of weeks at CES 2015.
Afterwards we are expecting to see the 4.5W Broadwell-Y and then the Broadwell-U. The Broadwell-U has TDPs from 15W to 28W and it comes in a BGA package. These processors are targeting the notebook sector from two in one convertibles to standard notebooks.
Broadwell-U comes with a choice of Intel HD Graphics 5500, Intel HD Graphics 6000 or Intel HD Graphics 6100. It supports Intel Quick Sync Video and resolutions up to 3840x2160@60Hz aka 4K.
The fastest Core i7 5000U series will replace the i7-4650U. This is dual core clocked at 1.7 GHz and with the turbo switched on it can reach 3.3GHz. Not bad for 15W. We hope that its Broadwell 14nm successor can outperform that.
The fastest Broadwell-U 28W replaces the i7-4578U dual-core with four threads clocked at 3.0GHz and with turbo this CPU can reach 3.5GHz, using 28W. The Broadwell-U 28W will be branded as Core i5 5000U series.
