Ok, so I've decided to make this account and make my first forum post ever because I couldn't find any other post about this.
Before I get into it, here are my specs :
Laptop: ASUS R510IU-LSFX
CPU: FX-9830P
GPU: RX 460
RAM: 8GB DDR4
So I know about the FX-8800P and others power throttling in games due to the 15W TDP limit, but I have an FX-9830P which has a 35W TDP, 3.0GHZ stock clock, and 3.7GHz boost clock. Ok, here's the problem. In games, the clock speed jumps between 2.19GHz and 2.6GHz and (rarely) sometimes hits 2.8GHz, but usually, it's down in the 2.1 - 2.3 GHz range in games. This is a problem because it causes major stuttering in my games. The RX 460 is capable of playing all of my daily games (Fortnite, World of Tanks, Killing Floor 2, Miscreated) but the CPU sits at 2.19 - 2.6Ghz in those games and causes stuttering and low frame rate, which is not what I expected. For example in the calm areas of Fortnite like the edges of the map, I get an easy 40-60 FPS with no dips, but god forbid I go into a town area or get into a fight, the smooth framerate goes away and gets replaced with a stuttering mess, which is worse than the old laptop that I "upgraded" from.
I recently upgraded from the MSI-GX60 that had an A10-5750M and a Radeon 7970M. According to cpu.userbenchmark, the FX-9830P was supposed to have given me a massive boost over the old A10, and the RX 460 is also slightly better than the 7970M:

But instead, because of the throttling, the performance is almost like it. I've already checked thermals on the CPU and the max temperature in games is at 76C. I've tried undervolting using AmdMsrTweaker and K15TK but they didn't make a difference. AMD Overdrive is not supported, AMD PSCheck doesn't install, I've already tried using the updated drivers from AMD, and the stock drivers from the ASUS website, and I'm using the dedicated graphics in games and have the High Performance profile set in Windows Power Options. It looks like it's power throttling because in-game the CPU is at the reduced clocks, but as soon as you close the games or minimize them, the clocks jump right back up to normal speed, which also scratches out the possibility of thermal throttling. When loading pages on chrome the CPU speed dips down to 2.19GHz but as soon as the pages finish loading it shoots back up to around 3.5GHz. When playing less CPU heavy games my CPU uses Turbo Boost the entire time and never dips below 3GHz, but when playing CPU Intensive games like State of Decay, Halo Wars 2, or Dying Light, the CPU rarely gets to and above 3GHz and makes the games pretty much unplayable while my GPU chills at 40-60% usage, which sucks because wouldn't these games demand higher clocks to run smoothly? Instead, the opposite happens, and the speed plummets. I haven't tested using this laptop with Unity3D yet, and hope the same doesn't happen there
I don't understand why this would be happening as the TDP of this CPU is at 35W, which is the same as the 5750M, which I've managed the lock the speed of that processor to 3.2GHz. It's not at 15W, the same as the ULV Intel processors and the FX-9800P/8800P, so the fact that it's downclocking baffles me. Although I haven't looked at it for a long time, the downclocking seems to be connected to the integrated GPU, and when the speed of the iGPU gets high, the processor downclocks, but why would the iGPU be used if I'm using the dedicated card for games? Yet again I haven't monitored it for a long time so I don't know for sure if that's the cause.
Wondering if anyone can help me because this is VERY frustrating, feels like I bought a downgrade instead of an upgrade :'(
