Arc Power vs CoreCtrl

Arc Power is a free Windows utility for Intel Arc graphics cards. It combines driver-backed tuning, hardware monitoring, graphics options, saved profiles and an in-game overlay in one application. Supported controls can cover clock speeds, power limits, temperature targets and fan behavior, depending on the selected GPU and its driver. The overlay reports clocks, temperatures, power, utilization, VRAM, FPS, 1% Low and 99% FPS readings, plus frame time. Alchemist cards can receive a negative voltage offset down to -200 mV. Named tuning profiles can be saved, loaded and set to apply when Arc Power launches. Graphics controls include XeSS Frame Generation, synchronization, frame limits, low-latency options and supported display settings. Reversible Windows graphics tweaks are also available. Arc A3/A5/A7 and B580/B570 are verified working; Arc Pro B50 and integrated Arc graphics are limited to tweaks and telemetry. Arc tuning needs an Intel Arc GPU, while AMD and NVIDIA cards may appear for telemetry. Windows 10 or 11 64-bit is required, with installer and portable downloads.

CoreCtrl is a free, open-source GNU/Linux application for controlling hardware through profiles. Profiles can launch when an associated Linux or Windows application starts, then restore their settings when it ends. You can also activate a manual profile, which takes priority over automatic profiles; only one manual profile can be active at a time. The project describes its AMD GPU controls as full, covering fans, frequency, power, sensors, and hardware and software information. CPU support is more limited: it includes a frequency-scaling governor control, a package maximum-frequency sensor, and CPU package information. Automatic profiles need an executable binary name, so they cannot be tied to scripts or interpreted-language applications. The available controls depend on the Linux kernel version and hardware. Full AMD GPU control with the amdgpu driver requires a boot parameter and reboot. CoreCtrl is free, with no paid plans stated, and the project recommends installation through a distribution package manager. It is in maintenance mode, with development focused on fixes and upkeep rather than new features or hardware support.
