Intel Core i7 2677M 

Released June, 2011
  • 1.8 GHz
  • Dual core
6.8 Out of 10

The core features were targeting a 2:1 ratio of performance to power, which would require new features and updates to improve performance by at least 2x while maintaining power levels.
by Ryan-Shrout (Aug, 2014)
Intel is basing the 14nm name on the 0.65x scaling rate seen with the combination of pitch adjustments on the tri-gate design, thus going from 22nm to 14nm is a 0.65x scaling rate.

Intel’s erratic Core M performance leaves an opening for AMD

by Joel Hruska |
Instead of absolutely guaranteeing that a chip will reach a certain speed at a given temperature or power consumption level, simply establish that frequency range as a “maybe” and push the issue off on OEMs or enthusiasts to deal with.
In several cases, the gaps in both CPU and GPU workloads are quite significant — and favor the slower processor.

More Intel Core M Coming Q4

by Ian Cutress |
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.
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 |
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.
