Last week I published some fresh Vulkan vs. OpenGL benchmarks of AMD/NVIDIA GPUs in AMDGPU-PRO vs. NVIDIA On Linux With OpenGL and Vulkan, but for those wanting some fresh Intel OpenGL vs. Vulkan Linux numbers, I have some fresh data to share this evening.

For your viewing pleasure now are some Haswell (Core i7 4790K) and Skylake (Core i5 6600K) benchmarks using the Linux 4.9 and Mesa 13.1-dev Git code as of this week. Tests were done with both OpenGL and Vulkan. Dota 2 is the primary test-case -- The Talos Principle with the latest Mesa Git was only hanging when loading with the Intel ANV Vulkan driver while the OpenGL renderer had worked fine.

Results from a Haswell and Skylake system around here; will also have some Broadwell i7-5775C results with its more impressive Iris Graphics up shortly.With Mesa 13.1-dev, Haswell is still limited to OpenGL 3.3 while Skylake has OpenGL 4.5. Both expose Vulkan 1.0 although as covered before the Haswell support has basically taken a back-seat to Intel's focus on mostly improvements for Broadwell/Skylake and newer.

At 800x600 the i7-4790K Haswell system was slightly faster with OpenGL over Vulkan, but with the i5-6600K Skylake system it was delivering much better performance with Vulkan: around 18% faster than OpenGL.

At 1920 x 1080, both systems had slower performance with Vulkan but the Skylake Vulkan performance was less impacted.

And the 4K results if wanting to torture the Intel graphics hardware...

That's it for new data tonight, stay tuned for more Linux Vulkan benchmarks shortly.
