Hey,
in order to squeeze a tiny bit more power out of my old laptop until i get a new one, i've wondered if undervolting the northbridge would be worth the time.
I'm currently using a A6-4400m APU, which has CPU, iGPU and NB on the same chip.
Less heat from the NB would obviously allow the CPU and iGPU to run on turbo-clock a bit longer.
However, since the entire chip has an TDP of only 35W, i'd guess the NB has around 3W (or maybe even less?), so undervolting it from 1V to 0,97 or something wouldn't really have any effect.
So, does anyone know what TDP the NB-Part on the mobile Trinity chips is?
I can't find anything like a factsheet on the internet unfortunately.
P.S.: I hope i'm in the right forum, it's kind of hard to find the right place for APU-related stuff.^^
