Here is some more complementary data to this week's Vulkan vs. OpenGL On Linux With Core i5, Core i7, Ryzen 7.

With having the Intel Xeon Skylake + Radeon RX 470 box powered up yesterday/today with the latest Linux 4.12 + Mesa 17.2-dev stack for the new Mesa KHR_no_error testing, afterwards I kicked off some fresh benchmarks with that system for OpenGL vs. Vulkan using the Phoronix Test Suite.
Vulkan vs. OpenGL Mesa 17.2 RadeonSI RADV

So here are those latest numbers with the latest open-source RadeonSI/RADV Linux driver stack as of this week.

Given the still-maturing state of RADV compared against to the mature RadeonSI Gallium3D OpenGL driver that receives a lot of work from AMD, Valve, and the community, there are many cases where the OpenGL performance is still superior, similar to our other recent articles:
Vulkan vs. OpenGL Mesa 17.2 RadeonSI RADV

Vulkan vs. OpenGL Mesa 17.2 RadeonSI RADV

Vulkan vs. OpenGL Mesa 17.2 RadeonSI RADV

Vulkan vs. OpenGL Mesa 17.2 RadeonSI RADV

Vulkan vs. OpenGL Mesa 17.2 RadeonSI RADV

Vulkan vs. OpenGL Mesa 17.2 RadeonSI RADV

Vulkan vs. OpenGL Mesa 17.2 RadeonSI RADV

But there are areas where the gap is at least closing:
Vulkan vs. OpenGL Mesa 17.2 RadeonSI RADV

Vulkan vs. OpenGL Mesa 17.2 RadeonSI RADV

And the occasional areas with good Vulkan support and RADV does well, so it can come ahead of OpenGL on RadeonSI:
Vulkan vs. OpenGL Mesa 17.2 RadeonSI RADV

Vulkan vs. OpenGL Mesa 17.2 RadeonSI RADV

What does remain consistent though is the Vulkan usage leading to lower CPU utilization:
Vulkan vs. OpenGL Mesa 17.2 RadeonSI RADV

Vulkan vs. OpenGL Mesa 17.2 RadeonSI RADV

Vulkan vs. OpenGL Mesa 17.2 RadeonSI RADV

Phoronix Premium members, any other interesting Vulkan tests you want to see on the horizon? I do also have some Vulkan CPUFreq/P-State Linux 4.12 fresh tests in the works as well as a CPU core scaling comparison between OpenGL vs. Vulkan, among other interesting Linux hardware benchmarks.
