Kaby Lake is the codename of the New Processor from Intel. Intel is known to produce high quality processors for years. Unlike the processors which were released previously by Intel, this processor only supports the current version of Windows which is Windows 10 and it is not backward compatible with the previous versions of Windows.
Kaby Lake will natively support the Usb 3.1 . It is the latest standard for data transfer between devices and is supposed to be fast.
The Kaby Lake consists of a 14nm semiconductor device fabrication node. The 2015 Apple Macbook and Macbook Pro use the 14nm Intel Processors. The IPhone 6s and 6s Plus which is powered by the A9 chip is built using the 14nm semiconductor developed by Samsung!
It is seventh generation family of Processors which is going to be launched by Intel and probably will be coming out in the 3rd Quarter of this year.
