Notebooks are one of the best devieces suitable for CPUgenie advanced CPU power management. This is because notebooks typically have very constrained thermal limits, and the heat is usually dissipated through the notebook's chasis - very close to the user's body.
Therefore, reduction in temperature would be felt almost immediately by the user. Also, notebooks usually have small fans for forcing the hot air outside. These fans are activated if the chasis itself is not able to dissipate enough heat - which usually happens during the heavy computing load. As they are very small, those fans have to operate at very high RPM (Rotations Per Minute) which, as result, has an unpleasant effect of noise. Notebook noise is usually even more disturbing than a typical Office PC PSU fan noise.
In addition, notebooks are running on batteries if the user is mobile. Saving CPU power, where CPUgenie helps, should have a positive effect on duration of notebook mobility - that is, battery life. This effect might work if the CPU runs on lower than faSctory default voltages.
To test CPUgenie efficiency on notebooks, we took Sony Vaio Z notebook. Vaio Z series is quite popular "executive" office notebook, with state-of-the-art 45nm Intel Core 2 Duo CPUs and GM45 "Montevina" Chipsets. Our model is equipped with Intel P8600 CPU that has a TDP of 25W.
First thing that can be noticed after starting CPUgenie is that number of P-states available is much higher than number of ACPI power states in BIOS/EFI (4) - you can view ACPI states by launching "Power Monitor" tool found on CPUgenie start page. Having higher number of P-states offers us a potential of fine-grain CPU speed control, with greater flexibility compared with Windows-defualt Intel CPU power manager (intelppm.sys)
Also, 45nm P8600 also has a SuperLFM mode. A very useful trick that CPUgenie has, related to SuperLFM - is that you can increase the SuperLFM frequency by modifying the SuperLFM multiplier. This would give you higher than default lowest frequency, while still running in SuperLFM mode. In the case of P8600, we can set SuperLFM frequency up to 1200 MHz, while default one is only 800 MHz. Windows CPU driver is able to use 800 MHz default SuperLFM only.
Ok, now it is time to do the actual voltage optimization. We will do this fully automatically - with the help of Voltage Optimization Wizard. Due to high number of P-states, the wizard will need some time to finish optimization. We took the shortest test, which will run for entire night. WARNING: we always recommend to do a complete backup of your data before running Voltage Optimization Wizard. This is because Voltage Optimization Wizard might hang/reboot the PC during the test and there is a small chance that accidental hang/reboot might corrupt files that are not flushed out of the cache yet.
Our test session required one reboot - on 2133 MHz the lower-than-stable voltage caused Windows to hang. CPUgenie has a smart recovery option, that select the last stable voltage after reboot, and continue the test with that lowest stable voltage in mind - so the higher frequencies would not be tested with voltages lower than this.
As we can see, we saved ~12.3W when CPU runs under full load on 2400 MHz. This might look small - but take into account that the ACPI TDP record for this frequency is 35W (estimated TDP for CPU running on 2400 MHz) - as the ~12.3W reduction came from CPU voltage reduction only, we can be fairly certain that we reduced the 2400 MHz TDP by more than third, moving the total TDP of the CPU quite below original 25W! This + heavy reduction in CPU temperature are definitely worth trying CPUgenie!
