Similar to our findings on other processors from Broadwell through Ice Lake, the Intel Gallium3D driver is rocking! Besides OpenGL 4.6, the performance for this new driver is generally far better off than the classic "i965" OpenGL driver in Mesa.
With the Core i9 9900KS I ran some comparison tests using the Linux 5.5 Git kernel and Mesa 20.0-devel as of this week.
In most OpenGL workloads, the Intel Gallium3D driver is showing mighty impressive results!
On a geometric mean basis across many different GL workloads, the Gallium3D driver comes out to being about a solid 5% faster on the Core i9 9900KS. Hopefully Intel is able to stick to their plans of enabling this driver by default for Mesa 20.0 due out around the end of February. See all of these Intel OpenGL benchmark results in full via this OpenBenchmarking.org result file.
