Intel Core i3 3120M 

Released September, 2012
  • 2.5 GHz
  • Dual core
6.5 Out of 10

The Intel Core i3 3120M is a dual core processor based on the Ivy Bridge series. The two cores sport a base speed of 2.5GHz, but Turbo Boost is not available. Through Hyperthreading, the two cores can support up to four simultaneous threads, leading to a better CPU utilisation. Much like all Ivy Bridge processors, this one includes 3D transistors, which improve energy efficiency, when compared to similarly clocked Sandy Bridge processors. Also like all Ivy Bridge processors, the 3120M includes an Intel HD Graphics 4000 and is also best suited for laptops, where even smaller ones can use it due to its smaller architecture.

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.
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.
