well, "a lot faster" was mentioned to be "10x faster than maxwell" according to some nvidia presentations i have seen on the net (e.g. http://wccftech.com/nvidia-pascal-gpu-gtc-2015/) ...
of course this won't directly translate into hashcat. agree on the 25-35% historically. they say this time the gap will be bigger though. i've read it's supposed to have 4 TFlops DP and 12 TFlops SP. That should - theoretically - mean approx. 100% performance increase compared to titan x, which would be solid. Theoretically.
The assumption of +100% is based on doing this calculus: number_of_shaders times mhz_core_frequency times 2 = flops -> for titan x that would be 1000*2*3072 = 6 tflops, which is half what pascal is supposed to offer. Since they cannot increase frequency to 2000 MHz they have to add cores to achieve the 12 TFlops SP. Which is just as good for Hashcat. Please correct me if i got this wrong.
