Early Intel i965 vs. Iris Gallium3D OpenGL Benchmarks On UHD Graphics 620 With Mesa 19.1
With the synthetic GpuTest OpenGL benchmarks, the Iris driver was already very competitive to the i965 Mesa driver on Mesa 19.1-devel.
The CPU usage while running GpuTest also tended to be lower with Iris Gallium3D, but in some tests it was still spiking noticeably higher than i965.
