![]() We can describe modern GPU as a set of many (100 – 10000) rather simple CPUs, connected to very fast dedicated RAM. Using GPU for computing can give you huge speed-up – 3x, 10x, 100x, or even more. Comparison of available drivers and support level with LuxMark you can check here (may include errors). PAL driver is good (but doesn't tested with RDNA2 & newer). Decent support level for AMD will be achieved only after maturing of Mesa Rusticl driver. For notebooks with AMD CPU + iGPU: if notebook has Nvidia discrete video card, then it is usable for OpenCL/GPGPU. Intel consumer graphics lacks FP64 support ( link1, link2). Use another solutions if you need OpenCL/GPGPU for professional usage. Support of OpenCL/GPGPU on AMD APU (iGPU) from AMD is near zero. For instance - discrete Vega (GCN5) - Radeon Rx Vega 56/64 or Radeon VII). Support of OpenCL/GPGPU on consumer AMD video cards with Linux is rather poor (Exceptions are cards with the same GPU chips as used in professional hardware. 6 Using GPU for ordinary applications (GPGPU).5.6.4 ROCm - Running on unsupported hardware.4.2 Sources of 3D (OpenGL & Vulkan) drivers.3.6 AMD ROCm drivers for OpenCL – for AMD GCN 5 and RDNA 1–3.3.5 AMD PAL – for AMD GCN 2 – GCN 5 and RDNA 1.3.3 Mesa 3D Rusticl - for different hardware. ![]() 3.2 Mesa 3D Clover - for different hardware.3.1 ATI FireGL – for Terascale 2 & 3 chips.
