Intel pstate needs to be activated as it does a far better job of managing CPU power especially in quad and octo core CPU like 3rd and 4th gen i7. The turbo is handled far better than cpu-freq. Best of all with Intel Thermal Daemon the temperature issue is non existent even under full load. Now the behavior is same as a Windows machine. Even power consumption with TLP installed is same as Windows. Ubuntu needs to activate the pstate driver in 3.11 for 13.10 and it would be a good idea to patch LTS 3.80 kernel with this driver if possible. Also Intel Thermal Daemon needs a PPA at least. Currently it has be be compiled in, its a must for maintaining heat in i7 IVB and Haswell for laptops as well as power efficiency.
