Hardware Support

AMD

LACT for the most part does not implement features on a per-generation basis, rather it exposes the functionality that is available in the driver for the current system. However the following table shows what functionality can be expected for a given generation.

• ✅ - Supported
• ✅* - Supported with certain caveats
• ❔ - Unknown, but theoretically supported
• ❓ - Unknown
• ❌ - Unsupported

Generation	Clocks configuration	Power limit	Power states	Fan control	Notes
RDNA4 (RX 9000)	✅	✅	❔	✅	Requires recent kernel and firmware versions. Fan zero RPM option will be available with Linux 6.15+
RDNA3 (RX 7000)	✅	✅	✅	✅*	Fan zero RPM mode is enabled by default even with a custom fan curve, and requires kernel 6.13 to be disabled. The power cap is sometimes reported lower than it should be. See #255 for more info.
RDNA2 (RX 6000)	✅	✅	✅	✅
RDNA1 (RX 5000)	✅	✅	✅	✅
Vega	✅	✅	✅	✅
Arctic Islands/Polaris (RX 400-500)	✅	✅	✅	✅
Volcanic Islands (R7/R9 300)	❌	❓	❔	❔
Sea Islands (R7/R9 200)	❌	❓	❔	❔	Requires the amdgpu.cik_support=1 kernel option
Southern Islands (HD 7000)	❌	❓	❓	❓	Requires the amdgpu.si_support=1 kernel option

GPUs not listed here will still work, but might not have full functionality available. Monitoring/system info will be available everywhere. Integrated GPUs might also only have basic configuration available.

Nvidia

Anything Maxwell (900 series) or newer should generally work. A recent driver version is highly recommended, as older versions have shown to have issues with certain configuration options such as clockspeed settings.

Intel

Functionality status on Intel GPUs:

• Clocks configuration - works on most devices, but there is no support for overclocking (clocks can only be adjusted within the default limits)
• Power limit - works on ARC dGPUs. The maximum power limit might not be reported by the GPU, so the UI will change depending on the current limit
• Monitoring - most values are shown on devices where they are applicable, dGPU temperature and fan speed reading might need a recent kernel version
• Fan control - not supported by the driver

Laptops

Fan monitoring or control might not be available on some laptops, because the fan is physically not connected through the GPU. This is a matter of hardware design, do not open issues regarding this. On such systems you should use other software for fan control which handles all fans instead of GPU only, such as CoolerControl.
