amdgpu-clocks vs Inno3D TuneIT

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.

INNO3D TuneIT OC & RGB Utility V5.02 is a free Windows utility for overclocking and RGB control on listed INNO3D GeForce graphics cards. Its controls include GPU and memory clocks, fan speed, target power, and target temperature. The home page displays GPU clock, temperature, fan speed, memory profiles, driver version, and BIOS version, with real-time GPU monitoring available. RGB settings let users select a mode, change brightness and effect speed, or create a custom effect. Users can also change software startup options. The listed release supports GeForce 50, 40, 30, 20, 16, 10, 900, and 700 Series cards and specifies Windows 11 or Windows 10 64-bit. INNO3D provides a download link and a technical support form requesting product details, hardware configuration, and a problem description. For RMA requests, the support form directs customers to the store where the graphics card was purchased.
