EVGA Precision X1 vs LACT

EVGA Precision X1 is free GPU tuning software for Windows, with controls for clocks, voltage, fans, RGB lighting, and monitoring. Its OC Scanner tests a graphics card for a stable overclock and offers additional testing modes. Users can set GPU and memory clocks, voltage, and independent voltage and frequency points. Fan speed, curves, and profiles are adjustable, though the available options depend on the graphics card. RGB controls cover graphics cards and NVLink Bridges; LED Sync can coordinate with other EVGA RGB components. On supported EVGA cards, the software provides real-time wattage monitoring and an on-screen display of system vitals. It supports up to 10 profiles with hotkeys and includes an in-game screenshot function. Listed system requirements specify GeForce RTX, GTX 16 Series, and GTX 10 Series cards, plus Windows 10 64-bit or Windows 8 64-bit. EVGA offers a standalone version and links to a Steam version. The listed GPU control features require EVGA graphics cards.

LACT is a free, MIT-licensed Linux tool for controlling and monitoring AMD, Nvidia, and Intel GPUs. It reports VBIOS, VRAM, hardware units, Resizable BAR status, and Vulkan features. Monitoring provides configurable historical charts for power, thermals, and frequency, plus throttling information and CSV export. Controls include power caps, AMD power states, GPU and VRAM clocks, and custom fan curves on AMD and Nvidia. Undervolting uses voltage offsets on AMD and VF curves on Nvidia. Profiles can activate according to running processes or gamemode status. A system service applies GPU configuration without depending on a graphical session and can run headless from a configuration file. LACT includes an OpenTelemetry metrics exporter and exposes a JSON API over a Unix socket or TCP. The TCP listener is disabled by default; remote TCP management has no authentication or encryption. Packages are listed for several Linux distributions, with Flatpak and Docker service-only options. Available controls vary by GPU generation, driver, and hardware.
