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 - the functionality is known to work
• Limited - the functionality is known to work, but has certain limitations
• Untested - the functionality has not been confirmed to work, but it should
• Unknown - the functionality has not been confirmed to work, and it is unknown if it does
• Unsupported - the functionality is known to not work

Generation	Clocks configuration	Power limit	Power states	Fan control	Notes
Southern Islands (HD 7000)	Unsupported	Unknown	Unknown	Untested	Requires the amdgpu.si_support=1 kernel option
Sea Islands (R7/R9 200)	Unsupported	Unknown	Untested	Untested	Requires the amdgpu.cik_support=1 kernel option
Volcanic Islands (R7/R9 300)	Unsupported	Unknown	Untested	Untested
Arctic Islands/Polaris (RX 400-500)	Supported	Supported	Supported	Supported
Vega	Supported	Supported	Supported	Supported
RDNA1 (RX 5000)	Supported	Supported	Supported	Supported
RDNA2 (RX 6000)	Supported	Supported	Supported	Supported
RDNA3 (RX 7000)	Supported	Supported	Supported	Supported	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.

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
