Intel has revealed more details about its Core M processor, promising greater power efficiency and 50% faster speeds than previous-generation CPUs.
Core M is the first built using Intel's Broadwell microarchitecture, which is the 14nm version of Haswell.
The Core M is intended for what Intel terms as "two-in-one" devices, such as the Lenovo IdeaPad Yoga 2 Pro and Microsoft Surface Pro 3 - machines that can double up as laptops and tablets.
The Core M has been designed, Intel said, to create the best possible blend of performance and mobility. Intel claimed this new processor will deliver up to 50% faster computing performance, and 40% better graphics performance when compared to the previous fourth-generation Intel Core processor.
The 14nm Core M is more power-efficient too, with Intel's figures suggesting devices featuring the new processor will benefit from a 20% increase in battery life when compared to previous generation 22nm chips. Intel also claims double the performance of four-year-old devices.
What's new in the 14nm Core M processors?
Intel has achieved this advancement in its technology by altering the design of its Tri-Gate transistors (also referred to as FinFET). Intel has managed to shrink the overall size of its individual transistors by growing the surface area of the fins/sources attached to each gate: the fins are now taller, increasing the surface area.
This has allowed Intel to reduce the fin count from three to two on a single transistor, in turn reducing the overall transistor size and meaning Intel can fit more transistors on a processor.
Adam King, Intel’s Director of Notebook Product Marketing, said the "Core M processor is designed to go into small, slim fanless devices".
