Here's something that doesn't make implicit sense on first glance. The reference GTX 980 Ti GPU is practically on a par with the more powerful Titan X at the two lower resolutions and overtakes it at 4K. What's happening?
The answer rests with the relative aggressiveness of the two cards' GPU Boost implementations. The Titan X card, also a reference model provided by Nvidia, boosts to 1,080MHz in this title and maintains that throughout the benchmark. The GTX 980 Ti on the other hand, specified with the same base and boost frequencies, jumps up to 1,170MHz, most likely due to the greater availability of TDP headroom.
A common theme that you will see from hereon in, the GTX 980 Ti runs its core frequency higher than the Titan X thereby mitigating its on-paper ALU and texturing disadvantage.
