The 14nm Difference - Intel Xeon & Intel Broadwell

Intel Xeon Processor

Intel latest processors, such as Intel Broadwell and Intel Xeon D, are manufactured with 14nm silicon technology and are the first commercially available high volume 14nm devices on the market.

What’s So Special About 14nm? 

As the silicon feature size reduces, chip designers can cram more technology into smaller spaces and this technology can consume less power, resulting in tremendous SWaP savings.

Considering the atomic radius of unstrained silicon is 0.111 nm, it is mind boggling to understand that a 14nm silicon feature is a mere 126 atoms wide! In order to create transistors in such a small area, silicon designers have moved to 3D structures, and for 14nm Intel chips, these are called Tri-gate (or FinFET) transistors, which use the vertical dimension to provide more silicon surface area per transistor.  

Intel’s next generation technology, slated for introduction in 2017, will feature 10nm technology, further reducing power requirements and adding more computing capabilities into even smaller packages. IBM has even demonstrated chips with 7nm features, but these are still experimental and not yet slated for production. As the feature size continues to decrease, chip suppliers and their fabs are pouring immense resources into ensuring these new technologies also come with the same high reliability that is needed for rugged and long-life embedded deployments.  

Curtiss-Wright offers processing solutions using Intel Xeon D processor technologies:
