Nouveau vs. NVIDIA R595 Linux Driver For Workstation Graphics Performance
The vkpeak program for testing the peak Vulkan performance capabilities with different data types is very synthetic, but for those curious... The NVK+Nouveau driver stack shows that for the peak capabilities it can come close to the NVIDIA Vulkan driver but falling behind in areas like the INT8 dot product and INT16.
Nouveau with Rusticl was hitting segmentation faults from the FluidX3D computational fluid dynamics OpenCL software when trying to run on this workstation.
A big limitation of Mesa's Rusticl OpenCL driver compared to the native OpenCL hardware drivers remains with much higher kernel latency.
For clpeak capabilities, Nouveau with Rusticl showed a ways to go in delivering similar OpenCL performance to the official NVIDIA R595 driver.
