GALAX Xtreme Tuner Plus vs LACT

GALAX Xtreme Tuner Plus lets users monitor and adjust GALAX graphics cards from a mobile device. It shows card temperature, frequencies, and fan speeds in real time, with controls ranging from 1-Click OC to more advanced overclocking. The app can also change fan speed and RGB effects remotely; up to 20 ARGB effects are available on specific cards with ARGB features. To link a phone or tablet with a PC, users scan a QR code in the PC app or enter the computer’s IP address. GALAX requires both devices to use the same SSID for wireless linking. The app can capture system status for sharing on social media. Android, iOS, and Windows are listed platforms, and a Windows download is provided for gaming gear support and GPU only. The iPhone app is listed at free and requires a GALAX graphics card and Xtreme Tuner PC software. GALAX says its Hong Kong company was founded in 1994 and was formerly known as Galaxytech.

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.
