It's been a while since publishing any fresh Intel Core i7 5775C benchmarks, the socketed Broadwell CPU with Iris Pro 6200 graphics, since normally it's busy in the daily benchmarking churn of the server room for Phoronix Test Suite / OpenBenchmarking.org / LinuxBenchmarking.com efforts. But with having been doing some maintenance on that system this week and loading a clean install of Ubuntu 16.10, I did some fresh benchmarks of the Iris Pro 6200 graphics using Mesa 13.1-dev and Linux 4.9, including a look at the OpenGL vs. Vulkan performance for the Iris Pro graphics.
Skylake benchmarks are done most often on Phoronix since it's currently the latest and greatest on the desktop side, but the Broadwell i7-5775C with its Iris Pro 6200 graphics still packs a lot of power. In this article are benchmarks of the Iris Pro 6200 by itself on OpenGL vs. Vulkan, the Broadwell Iris Pro performance compared to Skylake and Haswell HD Graphics, and then some other Mesa/kernel comparison benchmarks for this system.
First up with the OpenGL vs. Vulkan benchmarks of the Core i7 5775C, all tests were done from the latest Linux 4.9 Git kernel paired with Mesa 13.1-dev to provide the latest i965 DRI driver code as well as the open-source ANV Vulkan driver.
All of these benchmarks were conducted in a fully-automated manner using the Phoronix Test Suite. First up are the Dota 2 metrics as unfortunately The Talos Principle wasn't able to run on this system due to some Vulkan issues where when using the Vulkan renderer would constantly hang at the loading screen.
