Intel Core i5 480M 

Released January, 2011
  • 2.66 GHz
  • Dual core
6.2 Out of 10

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

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.

Intel Announces Core M Processor Lineup Using Broadwell-Y

by Ryan Shrout |
www.pcper.com
The Core M 5Y70 is the highest performance part with a base clock speed of 1.10 GHz that can scale up to 2.6 GHz with one or both cores active.
At least one partner has already announced a Core M product: the Lenovo ThinkPad Helix.
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.
The delays and fab cancellations that followed took a great deal of wind out of its sails, leaving us to wonder if the 14nm delays would push back the entire product stack.
This wouldn’t be the first time that Intel unleashed a vastly improved product that failed to grab much market attention.
