Evaluating Undervolt Performance - iGPU reduces CPU frequency
Evaluating Undervolt Performance - iGPU reduces CPU frequency
Hi everyone, I'm experimenting with undervolting my 10750H. Initial tests are promising, but using Prime95 and Furmark to stress both CPU and graphics has helped verify performance limits. However, after some time the clock speed drops significantly—between 3.2GHz and 3.8GHz—and when I reduce Furmark it briefly recovers to around 4.17GHz, which seems to be its peak. I'm concerned that lowering the CPU frequency might affect how accurately we assess stability. Any advice or insights would be appreciated!
Use another source instead of Furmark. This will give you two distinct datasets for analysis.
Good suggestion. I'll give it another shot. Although I recently tested with just Prime95, the performance slowed down over time. I'm not sure if the problem is related to undervolt or thermal throttling. According to HWinfo, 2-4 cores tend to throttle quickly, but my system stays around 4-4.1GHz and then briefly reaches high 3s before dropping again once it hits its thermal limit.
It's mainly about the power restrictions that are fixed on mobile devices. PL2 is generally permitted for about 20 seconds before switching back to PL1. https://www.gamersnexus.net/guides/3389-...text=Intel allows for up to,for the limited duration permitted.
