Ultra High Definition 4K - 3840x2160 Performance

Ultra HD Gaming at 3840x2160 with modern games

So on this page I want to show you an overview of rendering performance with a series of High-end and Enthusiast level graphics cards. “FullHD” 1920x1080 has become the industry standard within the display industry, but enthusiasts will never settle for just standard and are always looking for the next big innovation in technology. Ultra HD gaming is the next evolution in immersion that gamers have been waiting for. Commonly addressed as Ultra HD, UHD or 4K, this new resolution refers to the ultra-high resolutions with approximately 4000 horizontal pixels. Ultra HD resolution also has four times the number of pixels of a typical 1920x1080 resolution.

With four times the pixels, a new level of immersion can be created for gamers on a single display. Gamers will be able to experience richer details and a new sense of realism with the next generation of gaming on Ultra HD displays.

  • 16x AF
  • Internal benchmark
Again, for the single GPU cards, if you disable AA you will gain up-to a third in performance making the games playable enough. SLI or Crossfire however, bring it on. What we'll see continuously is that in Ultra HD the 970/980 SLI setups are not as fast as say two 780 Ti cards or a Titan-Z. This is due to a more limited 256-bit memory bus mostly. The higher clocks alone won't save the performance, for the 980 that does change a little as they have a little more rendering power under the hood.  The results overall are a bit of a mixed bag really.

Our scores are average frame rates so you need to take a margin in mind for lower FPS at all times. As such we say 40 FPS for overall should be your minimum, while 60 FPS (frames per second) can be considered optimal. Scaling for 3-way SLi on the 980 pretty much sucked badly for Tomb Raider.
