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. This happens everywhere from gaming to rendering videos, basically any kind of load triggered an automatic power throttle regardless of power source or temperature.
It happens while plugged in and on battery. 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. So we can rule the temperature out as well since the exact same issue occurred again.
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.
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.
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. 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.
