Moving to a 14nm process technology should give the GPU more thermal headroom and result in higher maximum clock speeds.
by Ryan-Shrout (Aug, 2014)
So some of the key aspects of the Broadwell microarchitecture would be to be suitable for fanless devices, deliver on core performance improvements and feature enhanced graphics, media, display capabilities.

In The News From around the web

Though not a performance powerhouse, I think the first taste of Broadwell is delectable and provides vendors with an amazing option that balances the performance of Haswell with the power efficiency of Bay Trail and the Atom lineup.
Newly branded as the Core M line, Broadwell-Y is meant to target the market looking for similar performance of today's ultra-low voltage Haswell processors but with longer battery life and more efficient designs.
The majority of the die is dedicated to the graphics core while there are two CPU cores and right below is a shared 4 MB L3 cache which is shared across the graphics and processor cores.
Since Core M is the first 14nm device, it will meet the demands of next iteration of mobility devices boasting better performance and efficiency.

Short Bytes: Intel's Core M and Broadwell-Y SoC

by Jarred Walton |
www.anandtech.com
Where previous Intel processors targeted laptops and desktops as the primary use case and then refined and adjusted the designs to get into lower power envelopes, with Broadwell Intel is putting the Y-series requirements center stage.
Shrinking the process technology from 22nm to 14nm can mean a lot of things, but the primary benefit this time appears to be smaller chip sizes and lower power requirements.

Intel previews Broadwell Core M

by Peter Scott |
www.fudzilla.com
Thanks to the new manufacturing process, Intel can essentially squeeze desktop-class performance into very thin form factors.
Products based on Broadwell Core M chips should start to appear towards the end of the year, but the silicon gods were not too kind to Intel.
