We tested using our updated 2015 Multi-GPU test bench, detailed in the table below. Our thanks tosupporting hardware vendors for supplying some of the test components.
The latest AMD drivers (220.127.116.11 with Doom support) were used for testing. NVidia's unreleased 368.146 drivers were used. Game settings were configured to "Ultra" with anti-aliasing set only to FXAA (no multi-tap). Resolution settings were configured to 1080p, 1440p, and 4K. We performed some additional low-end GPU testing with “Medium” settings at 1080p. Tests were conducted in the Foundry, level 2. The test path is in the video further above (pending upload).
Each scenario was tested for 30 seconds identically, then repeated three times for parity, per setting, per card – that's a maximum of 9 to 12 test passes per device.
FPS fluctuates heavily in the game. We chose one of the more intensive interior settings. Generally, card performance should be slightly higher than what's shown here – we didn't figure out a definitive “worst case,” but found a middle-of-the-road benchmark course in terms of intensiveness.

Average FPS, 1% low, and 0.1% low times are measured. We do not measure maximum or minimum FPS results as we consider these numbers to be pure outliers. Instead, we take an average of the lowest 1% of results (1% low) to show real-world, noticeable dips; we then take an average of the lowest 0.1% of results for severe spikes.
Graphics Cards Tested
PowerColor R9 290X 4GB (Deprecated)
Compiled DOOM Benchmark – R9 390X w/ Hotfix, 1080p / Ultra
1% frametimes have improved noticeably alongside the AVG FPS jaunt afforded by AMD's hotfix. The AVG FPS gap against the GTX 970 has closed from ~30FPS to ~10FPS, providing a boon to the 390X's performance. We measured no change in 380X or Fury X performance, and thus have not listed them above.
Compiled DOOM Benchmark – R9 390X w/ Hotfix, 1440p / Ultra
AVG FPS performance jumped from 51.33 to 62FPS at 1440p (+18.8%). The R9 390X now trails the GTX 970 by 4FPS (-6.25%), rather than -25%.
Compiled DOOM Benchmark – R9 390X w/ Hotfix, 4K / Ultra
4K performance gains were measurable, but not significant as a result of the heavy load placed on the system.
AMD's resolved some of its day-one issues, the 390X now outperforming the GTX 960 by much larger margins (as it should do) and reducing the gap vs. the 970 to ~12.6% at 1080p. That gap has thinned to ~6% at 1440p.
This test goes to show just how much the drivers are responsible for. Keep them up-to-date to avoid missing out on “free” performance.
We're posting this from the plane that will bring us closer to Taipei, so check back throughout the week from jet-lagged coverage from Taiwan, China, and elsewhere.
