Evening,
I recently got a mid-range laptop with a Ryzen 5 3500U and noticed some strange behavior with power consumption and clock speeds;
I would launch a light game, the CPU clocks would sit around the 2.4-2.9Ghz range, GPU clocks vary from game to game I guess but it usually starts at 900Mhz to 1.1Ghz, everything is cool, temps are in check (sub 70c), no thermal throttling, plugged in, everything's great. A couple minutes later, the CPU clocks drop to 2Ghz or under, GPU goes all the way down to 400-500Mhz and stays there regardless of the load/temp. CPU package power goes from the normal 10-11 watts down to 5-6 watts for no apparent reason. And the strange thing is that it stays like that for the rest of the gaming session, regardless of what happens. Same behavior whether the laptop is plugged in or not, it doesn't matter.
I tried every solution available (except Ryzen Controller which I don't wanna use), added hidden power options through cmd and tweaked them, windows battery slider is always on Best Performance...etc to no avail. No matter what options I change, it always behaves the same.
I also don't understand why it doesn't hit the advertised 15 watts TDP, it's designed to reach that so why is it not doing so? even when I stress test the CPU, FPU and RAM, it only ever scratches 12 watts max.
Provided some screenshots from AIDA64 to illustrate the problem.
This is driving me crazy, if anyone has any idea what the hell is happening and how to fix it your help is appreciated.
Thanks.
