Let's kick off our next-generation benchmarking with a look at the Radeon RX 460's performance in this year's reimagining of Doom. To test this fast-paced FPS, I mauled some demons while retrieving a yellow security pass in the early stages of the game's Foundry level. We created a custom blend of low and medium settings to make a playable framerate happen at 1920x1080 for these cards.
Out of the gate, the RX 460 takes a strong lead over the GeForce competition, and it even edges out the somewhat better-provisioned Pitcairn chip in the R7 370. The march of progess is a wonderful thing. The RX 460, R7 370, and GTX 950 cluster together in our latency-sensitive, 99th-percentile frame time result, while the Radeon R7 360 and GTX 750 Ti bring up the rear.
These "time spent beyond X" graphs are meant to show "badness," those instances where animation may be less than fluid. The 50-ms threshold is the most notable one, since it corresponds to a 20-FPS average. We figure if you're not rendering any faster than 20 FPS, even for a moment, then the user is likely to perceive a slowdown. 33 ms correlates to 30 FPS or a 30Hz refresh rate. Go beyond that with vsync on, and you're into the bad voodoo of quantization slowdowns. And 16.7 ms correlates to 60 FPS, that golden mark that we'd like to achieve (or surpass) for each and every frame.
None of the cards we tested spend any time past the 50-ms mark, an excellent result. The GTX 950 also turns in a perfect score at the 33.3-ms threshold. Both the Radeon R7 370 and the RX 460 spend barely any time past this post, either, while the 750 Ti and R7 360 struggle to varying degrees.
At the critical 16.7-ms threshold, though, the RX 460 spends a little over half the time on tough frames that the R7 370 does. Impressively, the pint-sized Polaris spends about a fourth of the time that the GTX 950 does past 16.7 ms, as well. The RX 460 was noticeably smoother than the rest of the cards I tested in Doom with Vulkan enabled. That's excellent performance from a chip ostensibly meant to replace the Bonaire silicon inside the R7 360. Let's see if this behavior carries over to the card's OpenGL performance.
