Default Power Saving Tools

Tried a few power saving tools. tlp on it's own gave some nice power saving, due to the way the CPU has been "underclocked" this translates into better iteration timings instead of lower power consumption. Adding powertop on top of tlp regresses the power savings:
Code:
CPU Clock     Power    Power At
  (MHz)     Target (W)  Wall (W)  ms/it   it/s   j/it  Command
  1400        11         21        5.55  180.2  0.117 "ryzenadj --stapm-limit=11000 --fast-limit=11000 --slow-limit=11000"
  1400        11         21        5.18  189.4  0.109 "tlp bat && ryzenadj --stapm-limit=11000 --fast-limit=11000 --slow-limit=11000"
  1400        11         21        5.28  193.0  0.111 "powertop && tlp bat && ryzenadj --stapm-limit=11000 --fast-limit=11000 --slow-limit=11000"
