    brother i am suffering for same problem in my Acer Nitro 5 amd ryzen 2500u mobile processer with rx506x graphics
    plz tell me if you get any solution
    i dont think there is a solution for this problem i think they intentionally locked the cpu to 1.6ghz maybe to give more battery backup

    but they should have provided option in bios to lock and unlock cpu so that users can choose according to their needs

    its depends on amd as ryzen mobile processor is fairly new and all we can do is wait but i think they shouldnot make the same mistake with 3rd gen ryzen mobile cpu's

  • Have you already updated to see if it solves the problem?

    It's not a bug, it is a feature, as confirmed by Acer support. I have an Acer Aspire A515-41 with A12-9720P and an Acer Nitro 5 AN515-42 with Ryzen 5 2500U, both with exactly the same issue. It is hard locked from the manufacturer for increased battery life, and nothing will change it.
    Strange ; if battery  life is the concern why doesnt CPU go below 1.6 ? Sounds like buggy engineering  
    Turbo boost is completely disabled in battery mode, so frequency stays fixed at 1.6, goes neither above or below.

    As I have written earlier on this thread, it's not a bug, it is a feature, as confirmed by Acer support. I have an Acer Aspire A515-41 with A12-9720P and an Acer Nitro 5 AN515-42 with Ryzen 5 2500U, both with exactly the same issue. It is hard locked from the manufacturer for increased battery life, and nothing will change it. It is a common issue on all Acer laptops with AMD CPUs.
    As far as performance it concerned, the reduced frequency does not really matter for daily usage. Of course, it affects heavy usage scenarios like gaming. However, the kind of slowness mentioned by some users should be attributed to the mechanical HDD rather than the CPU. Add an SSD, and ideally upgrage the RAM to dual channel 16GB, and then notice the change in performance!

    when using battery and doing programming tasks the laptop usually takes lot of time compared to when it is plugged in

    @Acer-Manny
     can't acer add feature in bios like you did for keyboard backlight to unlock the 1.6 freq lock when running on batteries what's the use of it being a gaming laptop when you cannot use it to its full extent
