Last week were some fresh AMD Dota 2 benchmarks while here are the numbers from Dota 2 with Intel Skylake HD Graphics 530 as of this weekend. Testing was done with the Linux 4.9 kernel and Mesa 13.1-devel as of this past week from the Padoka PPA on Ubuntu 16.10.
Beyond the OpenGL vs. Vulkan renderer tests at a variety of resolutions, the CPU usage was also monitored -- done automatically of course via the Phoronix Test Suite with having set the MONITOR=cpu.usage environment variable prior to initiating the tests.
At the very laxed resolution of 800 x 600, the ANV Vulkan vs. i965 Mesa driver performance on the HD Graphics 530 is basically the same.
The CPU average ends up being close between the two drivers and renderer implementations for Dota 2.
But as the resolution increased, the Vulkan performance with the current ANV driver code was quicker to drop than the mature Intel OpenGL Mesa driver.
At 1080p the CPU usage was around the same.
Really stressing current-gen Intel graphics at 4K...
Though the CPU usage did appear lower, albeit current Intel graphics hardware isn't meant for 4K gaming. More details via this OpenBenchmarking.org result file.
