What settings are you using in Ryzen Controller? I just bought this laptop and im getting the same issue It's ridiculous really, paying for hardware and then not be able to use it at full potential. I did manage to get better performance by forcing it to run at higher TDP using, but that's not something I'm comfortable running all the time since kids are using laptop primarily. I have latest BIOS installed and downloaded latest chipset drivers directly from AMD. Bought it for my niece as Xmas present, to use primarily for school/homework, but also some light gaming since I saw on YouTube reviews Ryzen 3500U running Fortnite comfortably over 60 fps, but mine barely does over 30 on lowest settings at 720p. I have the same issue with exact same model. The CPU according to AMD's spec page, is rated at 15 watts not 6, so by restricting its power allowance to almost a third, it looses a ton of performance and that's unacceptable. If this is programmed in the BIOS, like I believe, it would mean Acer is robbing us of compute power that we've paid for. If anyone has the same model even with an Intel CPU, please take 5 minutes of your time and test your CPU under load and report back. I want to know how many of you guys have experienced this? Is this behavior normal? Acer Support wouldn't tell me so I want to find out myself. So we can rule the temperature out as well since the exact same issue occurred again. At first I thought this was a temp issue, so I pulled out my portable air conditioning unit and let it blow cold air directly onto the bottom intake side of the laptop, it was idling at 12-15c and on full load at 48-52c.

It happens while plugged in and on battery. This happens everywhere from gaming to rendering videos, basically any kind of load triggered an automatic power throttle regardless of power source or temperature.

I noticed something strange with the Ryzen 3500U on my Acer Aspire 5 A515-43 namely that after around 100 seconds or so, it automatically throttles itself down to ~6 watts (CPU Package Power) from ~10-12 watts.
