| Supported GPUs | The project lists Arc A3/A5/A7 and Arc B580/B570 as verified working, while Arc Pro B50 and Arc integrated graphics are limited to tweaks and telemetry. | It supports GeForce GPUs based on Pascal, Turing, Ampere, Lovelace, and Blackwell, with a best-effort fallback for future architectures. |
In their own words
Arc Power
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.
Green Curve
Green Curve is a free, open-source utility for adjusting NVIDIA GeForce GPU behavior on Windows and Linux. It can inspect and edit live voltage/frequency curves, core and VRAM offsets, power targets, and fan settings. Supported GeForce architectures run from Pascal through Blackwell, with a best-effort fallback for future architectures. Users can save five profiles, switch them with global hotkeys, or switch automatically based on the foreground application. Fan options include driver auto, fixed speed, and temperature curves with up to eight points. A command-line interface supports hardware probing, profile changes and live-state output in text or JSON. Windows has a native GUI; Linux has a keyboard- and mouse-navigable terminal UI. The application loads NVAPI and NVML from the installed NVIDIA driver rather than bundling proprietary driver binaries. The project states it has no telemetry, analytics, cloud tracking or remote error reporting. Windows x64 and Linux x64 are validated on NVIDIA hardware; ARM64 platforms are compile targets without completed live hardware validation. The project warns that tuning may cause instability or hardware damage.
