Four new Intel Core M processors coming later this year

A couple of months ago, Intel announced their Core M series mobile processors based on the new 14nm Broadwell architecture. These processors brought a number of new advancements in terms of how small and quiet tablets can get. 11.6-inch 8mm thick, fan less tablets with full x86 platform are made possible with the help of these new Core M processors. A latest report suggests that Intel will be expanding the Core M lineup with the addition of four new processors later this year.

Core M 5Y71 is the new top-end processor with slightly higher CPU and GPU clocks whereas everything else including the TDP stays the same. Its CPU cores now go up to 2.9 GHz whereas its GPU has turbo frequency of 900 MHz as compared to 850 MHz of 5Y70. Next up is the 5Y51, which has same CPU clocks but comes with slightly higher GPU clocks and loses vPro capabilities. Then comes with 5Y31 which is a slightly slower version of the 5Y51 as it comes with lesser CPU and GPU clocks. Then there is the 5Y10c which, as the name suggests, is a slightly improved version of the 5Y10a as it comes with slightly higher GPU clocks.

All in all, the new SKUs bring nothing new. They are only filling up the gaps between the processors that were released earlier. One notable thing is that Intel has now bumped IGP’s base frequency to 300 MHz on all new models, whereas the turbo frequency now goes as high as 900 MHz  on top models.

The Core M processors that were unveiled earlier have already started making their ways to end products like Lenovo Yoga Pro 3. The new processors are expected to be available to OEMs in Q4 2014 which means that end users will probably see them in products in early 2015.
