GeeCoolPerformance mode on the 13500HX works like its siblings: big gains on heavy loads, nothing on light ones. This i5 HX starts with a lower power ceiling than the i7 parts, so performance-mode gains are more modest.
Daily advice: performance mode for plugged-in renders or games, balanced for work. Want quiet or battery life? Cap power in the control center. Judge the mode by actual tasks and measured data, not the name.
