IDF 2014: Intel Core M: PCN new stepping and floating TDP – Clubic

Intel launches new micro-architecture Broadwell on the segment of ultra-mobility with the variant-Y Broadwell marketed now. Problem before the start of the IDF we learned that the new Core processors M were dying! Why? And what about the particularly attractive announced by Intel TDP of 4.5 Watts? Explanations

This is through a Product Change Notification PCN or we learned to everyone’s surprise that the new Core processors M were dying and on 26 September. A notification was enough aback all Intel quoted changing market conditions to explain the purpose of commercial life. We obviously questioned Intel’s representatives on the occasion of this IDF to try to learn more. During a first round table, Kirk Skaugen, Intel Senior Vice President, we stated that this judgment of the marketing was related to a problem with the Stable Image Program that enables business customers create images for deployment of their systems by ensuring that nothing changes on the particular firmware or drivers side platform. And explain that the reference to changing market conditions was probably a mistake here reused generic use.

Unconvinced by this first explanation we asked other people at Intel. And that’s where things get interesting. It turns out that a new stepping of the Core M arrives. This is the stepping F. No information against by the changes brought by the new stepping, its potential impact on the frequency or the problem it is supposed to correct stepping. Ultimately therefore the first buyers of platforms Core million benefit from a processor that will evolve in the near future a new revision … The question it changes and hope that Intel does not correct a bad bug here. All that accredits however feel that Intel has pushed its schedule for 14nm processors out of the end of 2014 as announced … even make some sacrifices.

On another note, we asked about Exact specifications TDP of Intel Core processors Mr. ad here a relatively low TDP of 4.5 Watts. It turns out that it is programmable upward or downward by the computer manufacturer, 3 to 6 watts. Well and I promise this is not a PDS, the former name briefly adopted by Intel to try to better position themselves to compete, renamed TDP. That calls knowing that previous Haswell-Y had a TDP of 11.5 Watts. In truth, if we recall that the T Intel TDP is the thermal properties, the Turbo mode processors like the Core M increases the TDP for the space of a few seconds. . And here according to our interlocutors, the Core M can consume up to 15 Watts peak

For this, Intel also added an additional parameter in the algorithms of temperature management: in addition to controlling CPU temperature, it is also relying on the chassis temperature, what Intel calls the Active Skin Temperature Management. It’s pretty smart and clever but in fact it also will determine if the manufacturer is developing a chassis cooling will be better quality and top performance, conversely if the manufacturer magnifying glass, the chip will heat quickly and performance will be reduced. Continuous use, we were able to take control tablets Core M which we were particularly hot at the location of the processor. Ultimately therefore announced the TDP Core M seems to be a middle value, not an absolute value.

M Core So what’s your TDP
