G-Helper vs Universal x86 Tuning Utility

G-Helper is a free, portable Windows control tool for Asus laptops and handhelds. It brings together performance, fan, GPU, battery, and RGB controls in a single executable that does not require installation. Performance modes are Silent, Balanced, and Turbo, with built-in fan curves; GPU modes are Eco, Standard, Ultimate, and Optimized. Dedicated GPU controls include core and memory clock offsets, GPU power, Dynamic Boost, and temperature limits. Automation can change performance mode, GPU mode, screen refresh rate, and keyboard-backlight timeout according to AC or battery power. An in-game overlay reports FPS, CPU and GPU temperatures, fan RPM, and power draw. Selected Asus mice, keyboards, and headsets can have lighting, bindings, equalizers, and battery settings. The app checks Asus for model-specific BIOS and driver updates and uses the Asus System Control Interface driver plus BIOS-stored operating modes. It requires the .NET 10 Desktop Runtime and that Asus driver. The desktop application says it does not collect or transmit personal data.

Universal x86 Tuning Utility (UXTU) is a free Windows utility for adjusting processor and GPU settings on x86 laptops and computers. It works best with Zen-based CPUs or APUs and Intel CPUs from the fourth generation onward. Users can select premade presets, save custom ones, or choose Adaptive Mode, which monitors processor temperatures as it adjusts power limits. The app also has Game Library, System Info, and Automations sections. AutoOC monitors CPU and memory instability signals and changes Curve Optimiser offsets for Zen-based CPUs and APUs. Version 26.3.0 added an in-game overlay, preset backup and import, tray shortcuts, Windows power-plan options, Intel presets, and experimental Zen6 support; games with anti-cheat may not always work with the overlay. Windows installer and portable downloads are available. The latest stable release requires .NET 10 64-bit, PawnIO Driver, and Microsoft Visual C++ Redistributable. UXTU is free under GPL-3.0. The project describes itself as a work in progress and warns that misuse may cause instability or malfunction.
