Intel's Gallium3D Driver Is Running Much Faster Than Their Current OpenGL Linux Driver With Mesa 19.3

Last month I did some fresh benchmarks of Intel's new open-source OpenGL Linux driver with Mesa 19.2 and those results were looking good as tested with a Core i9 9900K. Since then, more Intel Gallium3D driver improvements have landed for what will become Mesa 19.3 next quarter. In taking another look at their former/current and new OpenGL drivers, here are fresh benchmarks of the latest code using a Core i7 8700K desktop as well as a Core i7 8550U Dell XPS laptop.

This month so far Intel's new Gallium3D OpenGL driver has seen OpenGL 4.6 support added, an optimization to help the Java OpenGL performance (one of the deficiencies noted by our earlier rounds of benchmarks), and other performance work.

For some weekend benchmarking fun I tested the Core i7 8700K desktop and Dell XPS 13 laptop with Core i7 8550U graphics while comparing the OpenGL driver options. The driver state for both the i965 and Iris Gallium3D drivers were of Mesa 19.3-devel Git as of this week and also running with the near-final Linux 5.3 kernel.

With Mesa 19.3 due out in December, this is the first release where Intel developers are planning to default to their Gallium3D driver for Broadwell and newer. That change-over hasn't happened yet but based upon our testing, it certainly is looking feasible.
