Intel appears to have pulled out another card from its sleeve - the brand new Tremont architecture which marks the first major update since Bay Trail was released in 2013 and an architecture that will succeed Goldmont+. This will be the first 10nm process for this family of products and will be used in the Lakefield platform which brings the concept of Big.little cores (something smartphone tech enthusiasts would undoubtedly be aware of) to the x86 mobility product sphere. Mixing 'big' Sunny Cove and 'little' Tremont, Lakefield is set to offer a distinct upgrade over existing x86 setups today and will offer superior performance without the cost of battery life for mobility devices.

Here is what the official description for the Intel Tremont unveiling event at the Linley Fall processor conference reads:
