Steam Deck OLED Undervolt Efficiency and Performance Scaling (discuss.tchncs.de)

Hello, today I tested the performance and efficiency gains of my Steam Deck OLED at different TDP settings. As a benchmark i used 3DMark Firestrike. Which might not be the best benchmark for the Steam Deck, because it renders at 1080p. But you can still get good information from the results....

thubn,

The 20/50/50 UV gives 4% more performance compared to stock when both run at 10W TDP (column C and column J). And in this benchmark you don’t gain much performance past 10W (you can see this in row 27 on the right side)

thubn,

Thank you for the feedback. I decreased the amount of decimals to 1 and changed the percent values to the percent format.

thubn,
  • The stable undervolt for my deck (20/50/50) has roughly the same performance at 9W as the default 0/0/0 at 10W.
  • an easy 10/10/10 undervolt can give you 2% more performance
  • the 20/50/50 undervolt nets a 4% performance increase
  • firestrike on steam deck doesnt scale well with more than 10W APU power
  • if you want to undervolt your steam deck you should always check if its stable and increases the performance
thubn,
