Benchmarks: Metro Redux, Tomb Raider
The GTX 480 delivered 28fps at 1080p in Metro Redux while the GTX 580 only offered 4fps (14%) more. The performance jump from the GTX 580 to the GTX 680 was much larger, though at 34% it wasn't quite as significant as the 40% plus gains seen in Crysis 3 and BioShock.
Next we have the GTX 780 which was 28% faster than the GTX 680, while the GTX 780 Ti was 13% faster than the GTX 780.
Alhtough we saw gains of 10% or less when comparing the GTX 980 to the GTX 780 Ti in Crysis 3 and BioShock, we find rather different results when testing with Metro Redux as the GTX 980 was 27% faster than the GTX 780 Ti, hitting 79fps.
This margin was reduced to 21% in favor of the GTX 980 at 2560x1600, while most of the other figures remained within a 3%~ margin.
Tomb Raider was playable on the GTX 480 at 1080p with anti-aliasing disabled. Nonetheless, with the GTX 480 only offering 31fps, the GTX 580's 19% performance bump wouldn't go unnoticed. Again, the GTX 680 provided a significant jump from the GTX 580, as we saw 43% more performance in Tomb Raider.
This time the GTX 780 was 32% faster than the GTX 680 while the GTX 780 Ti was 14% faster, and the GTX 980 was just 10% faster than the GTX 780 Ti with 8fps more.
Interestingly, boosting the resolution to 2560x1600 went in favor of the GTX 780 Ti as the current flagship GTX 980 was just 4% faster.
