4K Ultra HD Graphics Card Testing On Ubuntu 14.04 LTS

The ASUS motherboard on this Kaveri system with the Xion PSU would crash due to reported voltage instability when running the GeForce GTX 780 Ti for Xonotic, so that result is left off for the last of our test results.

With Xonotic at ultra quality image settings for the 3840 x 2160, all of the tested modern AMD/NVIDIA GPUs were delivering playable 60+ frame-rates on average with the exception of the GeForce GTX 650. For this popular open-source game, the GeForce GTX 760 and GTX 770 were dominating over the AMD hardware to the point of sharply beating even the Radeon R9 270X and R9 290.

With the "ultimate" image quality settings at 3840 x 2160, only the higher-end Radeon and GeForce graphics cards on their binary Linux graphics drivers were pushing above 60 FPS. The new GTX 750 Maxwell series were among the hardware that couldn't push above 60 FPS at 4K for this Linux game configuration.

In looking at all of the results, there still persists some odd AMD Radeon performance issues on Linux with Catalyst (mostly with the R9 290 Hawaii; hopefully I'll be able to get some questions answered later this week at GDC) but aside from that these numbers would mostly be in line with expectations for running a 4K Ultra HD monitor on Ubuntu 14.04 Linux.
