amdgpu-clocks vs ASUS GPU Tweak III

amdgpu-clocks is a free, GPL-2.0-licensed Linux script for setting custom power states on AMD GPUs that use the amdgpu kernel driver. Where the hardware exposes the controls, it can adjust GPU and memory clocks, voltages, power caps, performance levels, and power profiles. The project says it should work with Polaris, Vega, Navi, and RDNA cards, but Vega GPUs in AMD APUs lack the required API. It can manage multiple cards, with custom state files selected by card identifier or PCI address. Users define settings in files under /etc/default. Fine-grained control requires Radeon OverDrive to be enabled in the kernel. A systemd service can apply states at startup, and a resume script can reapply them after suspend. For RDNA 3 and newer, it can handle driver-exposed Zero RPM fan settings; these require Linux 6.13 or newer, and stop-temperature control is available only on RDNA 3. A restore option returns states to their initial defaults, except the power profile, which it sets to 0. The README directs installation to /usr/local/bin; the GitHub releases page lists no releases.

ASUS GPU Tweak III is free Windows software for adjusting parameters on NVIDIA and AMD desktop graphics cards, including overclocking, voltage, and fan control. OC Scanner automatically optimizes clock speeds for NVIDIA cards and saves a profile without overwriting driver data. The Voltage-Frequency Tuner manages the GPU boost curve through multiple input methods. Profile Connect can load linked overclock, fan-curve, and OSD settings when a selected application runs. Users can configure GPU fans and system fans connected to FanConnect headers with curves or fixed RPM settings. Monitoring includes fan RPM and system power metrics, system information over full-screen apps, and log export for analysis. A hardware plug-in adds real-time component statistics, while the OSD has adjustable display properties. ASUS lists Windows 10 and 11, 2 GB RAM, and 200 MB storage as minimum requirements for most versions. Power Detector+ compatibility is limited to specified ROG cards. The listed stable release is version 2.1.9.5, dated September 18, 2026.
