A couple of benchmark results of what is claimed to be the NVIDIA GeForce GTX 1080 have been submitted to the Ashes of the Singularity benchmark leaderboard. Overall, the new card seems to be about 10-12 percent faster than AMD's Radeon R9 Fury X in this DirectX 12 game. As always I suggest taking these leaks with a grain of salt, we can't verify the accuracy and the performance levels indicated below are just a snapshot in a single benchmark with non-final drivers. Reviews of NVIDIA's Pascal cards are expected later this month.
In the games built in benchmark, the R9 Fury X is able to achieve a score of 4300 points with an average framerate of 44.4 FPS, with the Nvidia GTX 1080 achieving a higher score of 4900 and an average framerate of 49.6.
In Ashes of the Singularity, the Nvidia GTX 1080 has framerates that are around 10-12% higher than AMD's R9 Fury X. These scores were provided by the same gamer on the same system, so this comparison should be fairly accurate.
