The Open-Source NVIDIA "Nouveau" Linux Driver Performance At The End Of 2018
As it's been a while since last looking at the NVIDIA vs. Nouveau Linux OpenGL driver performance, here's a look at the current performance difference as the end of the year quickly approaches. This benchmarking roundabout features multiple generations of GeForce GPUs while testing with the NVIDIA 415 proprietary driver against the Nouveau stack on Linux 4.19 and Mesa 19.0-devel.
Sadly there isn't much positive news to report as 2018 draws to a close for the open-source NVIDIA scene... The main highlight of the year is the ongoing work by Red Hat (Karol Herbst and others) on bringing up SPIR-V/compute support to the Nouveau driver and somewhat related work by Jerome Glisse around Heterogeneous Memory Management and the new Heterogeneous Memory System with Nouveau driver support. The Nouveau SPIR-V compute support isn't yet mainlined but hopefully will be in 2019.

Samsung, Red Hat to Work on Linux Drivers for Future TechThe metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. |
