Intel is currently selling its well known Bay Trail-M SoC under Pentium and Celeron brands and it is doing a great job. Consumers can hardly know if they are getting what we use to know as Atom or that this is a Core based architecture, and Intel sales are benefiting from that fact.

The fastest of them is the Pentium N3540. Launched in Q2 2014, this part has four cores and four treads and its clock speeds goes from 2.16GHz base to 2.66 GHz in burst mode. It comes with 2MB of cache and it supports 64-bit computing. This is a 22nm processor with a top TDP of 7.5W and Scenario Design Power (SDP) of 4.5W. This processor is going to sell in notebooks and detachable systems until the end of the year and in Q1 2015 it will be replaced by the 14nm Braswell architecture.

Braswell will also replace some Celerons, including the N2940 that works at 1.83GHz to 2.25GHz, has four cores and the same 7.5W TDP / 4.5W SDP. The 14nm Braswell can definitely get faster frequencies at the lower TDP, this is what you can expect from smaller transistors.

Intel has also promised a lower Bill of Materials (BOM) with 14nm Braswell devices, but we don’t have any concrete figures at the moment. We expect entry level Pentium and Celeron based notebooks and detachables to end up with a similar price as the Bay Trail-M 22nm platform.
This incarnation of Braswell is coming in Q1 2015, shortly after Broadwell Y, low power 5th generation Core processors start shipping. Braswell is definitely going to end up cheaper than Broadwell and it will support Windows 8.1, Android, Chrome OS and Linux.
