EVGA Precision X1 vs PenguinBurner

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.

PenguinBurner is a free, open-source Linux application for tuning NVIDIA GPUs through automatic undervolting, overclocking, and per-game profiles. Auto-UV runs a managed Q2RTX benchmark and CUDA load, then finds and verifies stable voltage-frequency settings. Adaptive mode switches among saved Efficiency, Balanced, and Performance tiers to pursue a game's FPS target and reduce power use when headroom exists. Profiles work with Steam, Lutris, and Heroic, applying at launch and restoring the standing profile when a game exits. An overlay can display base FPS, frame-generation FPS, latency, clocks, power, temperatures, and the active tier. Manual voltage-frequency and fan-curve editors are included, along with a generated silent fan curve. The install guide lists NVIDIA RTX 30, 40, and 50 cards and requires the proprietary NVIDIA driver and CUDA. Linux installation options include pip, Flatpak, Fedora COPR, AUR, and Ubuntu PPA packages.
