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
