Intel's Haswell Refresh platform for desktops is anticipated in June 2014, but these chips will require a new motherboard. The first Broadwell-based chips are expected to follow in Q3 2014 but only for laptops at first.
Intel is expected to release the Haswell Refresh platform in June 2014 for the desktop market, but for the notebook segment, Intel is set to release its 14nm Broadwell-based U, Y and H series processors in the third quarter of 2014. There will be no updates for its N series processors for conventional notebooks.
