It's noteworthy that the TXP is the only GPU which can breach 60 fps in 4K. Furthermore, If you compare the jump from the 1080 to the TXP, it's just 1% in 1080p. it then jumps a massive 22% in 1440p and then finally goes up to 28% in 4K.
I wonder if it's just the VRAM which is the difference or if it's something more.
P.S. Did they stop benchmarking the 980 Ti? CB usually had a very large selection of GPUs in their testing, second only to TPU. I guess one can always take the GTX 1070's results and just multiply it by 0,95 to get an guesstimate, but still, somewhat surprising if they just stopped. It's a widely used card to this day.
