Journalists (including TR’s Scott Wasson) are gathered in Montreal this week for an Nvidia event. It so happens that AMD is right next door to the Nvidia venue, armed with one of its upcoming Radeon R9 290X graphics cards—and it’s taken the opportunity to release some internal benchmarks comparing that card to Nvidia’s GeForce GTX 780.

The numbers show the R9 290X beating the GTX 780 in two games, BioShock Infinite and Tomb Raider, at a 3840×2160 resolution. In case you’re wondering, that’s the resolution of Asus’ PQ321Q, one of the first desktop 4K monitors on the market. Here’s everything AMD is making public at this juncture:

BioShock Infinite Setting: 3840×2160 systemspec=ultra AMD Radeon R9 290X "Quiet Mode" average frame rate: 44.25 NVIDIA GTX 780 average frame rate: 37.67 Tomb Raider Setting: 3840×2160 16xAF Tressfx=off aatype=fxaa texturequality=ultra shadowmode=on shadowresolution=high ssaomode=ultra dofquality=ultra reflectionquality=high lod=ultra postprocess=on highprecisionrt=on tessellation=on AMD Radeon R9 290X "Quiet Mode" average frame rate: 40.2 NVIDIA GTX 780 average frame rate: 34.5

The R9 290X outruns the GTX 780 by 18% in BioShock Infinite and by 17% in Tomb Raider. Not bad.

Now, I should point out some caveats. First, these results come from AMD itself, and we haven’t verified them just yet. Heck, we don’t even know which parts of the game and which drivers were used for testing. Second, the numbers were run on a 4K display; performance at more pedestrian resolutions might be different. Third, AMD is quoting only FPS averages, which don’t tell the whole story. I wouldn’t expect average FPS figures to be too terribly off the mark on single-GPU setups like these, though.

We’ll have a full set of homebrewed R9 290X results as soon as AMD’s press embargo lifts, so stay tuned.
