Shortly after Videocardz published Fire Strike and Fire Strike Ultra benchmark scores of the new NVIDIA Titan X, more test results emerged on Gamestar.de and PCWorld.com. All the results gathered appear to be taken with a settings at max and resolution at UHD, apart from 3DMark scores apparently.
In the case of the results from Gamestar.de you see that the NVIDIA Titan X Pascal has been compared to several aother cards and as we predicted NVIDIAs new flagship is approximately 30% quicker on average than then GeForce GTX 1080, with differences ranging between 25 and 35%.
PCWorld on the other hand is comparing different systems. This give will give you a general overview on the performance level in different environments, but it won't allow to precisely tell the differences between the specific cards.
