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.

More Intel Core M Coming Q4

by Ian Cutress |
www.anandtech.com
All new CPUs are slated for a Q4 launch, which would mean that they might become available for end users in products on the shelf sometime in Q1 2015.
These initial CPUs should be properly available to the public in Q4 in devices such as the Lenovo Yoga 3 Pro using the Core M-5Y70.
One of the main graphs Intel was pushing in their briefing was this one, indicating what power is required for a fanless tablet.
With the 12.5-inch size and 7.3mm width, it sounds like the T300 Chi will be modifying the Core M CPU to be around 4W in order to keep the 41C skin temperature as a maximum.
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.
