I have an Huawei notebook with Ryzen 3550H CPU. the detail configure is as below.
The CPU frequency could go around 3.5Ghz with AC online, but the CPU could get strange frequency in battery mode. During battery mode, the cpu can only be 2.4Ghz, but can be 3.5Ghz if GPU decode is working. details as below. is there any reason of the issue?
|Power Mode||GPU graphic version||GPU decode||CPU boost frequency|
Is anything i can do, like change the register setting, to let CPU can boost to 3.5Ghz in battery mode without GPU decode working?
- Most browsers all you to turn off hardware acceleration.
- Power & sleep in settings, then Additional Power settings allow you to see power settings, and the differences between plugged-in and battery modes.
After more tests, I found the cpu package power budget will be set to
And, the old 19.12.3-Dec18 version graphic driver don't have this issue. i wonder if anything i can set to the new drivers to remove the power budget limit?
