Intel will launch 14nm-based Core M series processors specifically for use in fanless notebook/tablet 2-in-1 models in the fourth quarter of 2014, with many models to be exhibited at the Intel Developer Forum to take place in San Francisco September 9-11, 2014, according to supply chain makers.

Intel will release five processors under the Core M series including the 5Y10, 5Y10a as well as enterprise vPro 5Y70, initially to replace its seven 22nm Haswell-based processors including Core i7-4610Y, Core i5-4320Y and Core i3-4012Y, the sources noted.

The CPU giant will continue to have Haswell-based processors such as the Pentium 3516Y and Celeron 2961Y defend its entry-level territory, the sources noted.

Following the releases of Core M processors, Intel's 14nm Broadwell will become available in 2015. The H series Core i7 processors will be released in the third quarter of 2015 and Core i5 processors are unlikely to show up until the end of 2015.

Intel will also upgrade its existing 22nm Haswell processors including Core i7-4960HQ and Core i5-4200H in the fourth quarter of 2014.

The M series will continue to be propped by Intel's 22nm Haswell-based processors until the third quarter of 2015, but will receive upgrade in the first quarter of 2015. Meanwhile, the U series will receive three upgraded CPUs in the fourth quarter of 2014, but will be replaced by Broadwell architecture in the first quarter of 2015.

For the entry-level Pentium and Celeron N series, Intel will not release next-generation Braswell-based processors until the second quarter of 2015. The existing processors including Pentium N3530 and Celeron N2930 will also be upgraded in the fourth quarter of 2014.
