The world is changing and analysts are scared that ARM and companies that make ARM based chips can challenge Intel on many fronts.

It has been proven that ARM can do well in mobile phones and tablets, and now it wants to put more pressure on Intel and AMD on the notebook and server side. But at the same time Intel wants to become a bigger deal in the phone and tablet industry.

We have mentioned these highly efficient processors a few times this year. They are derived from the Y-processor line that normally has a 13W TDP and 7W SDP (Scenario Design Power). Intel can lower some clocks and get these processors to work at 6W TDP or lower making them compatible with fanless tablets.

In the real world these chips have a solid thermal throttle balance and once the chip hits the thermal maximum, which is around 4.5W to 5W for tablets, the chip would automatically drop the clock in order to cool itself down.

There is a big chance that Intel fanless tablets could perform much better than quad-core Cortex A15 chips from the top of the line including the Qualcomm Snapdragon 800 and Nvidia Tegra 4, but this is something that we have to see.

Y-series processors with 13W TDPs based on Haswell, fourth generation of Core processors, are scheduled for Q4 2013 launch and so are the tablets based on a slower version of these processors with 4.5W max TDP.

Currently the lowest TDP for notebook processors are Core i7 3689Y and Core i5 3439Y based on Ivy Bridge with plans to get them replaced in Q4 2013 by the Core i7 Y-series based on Haswell.
