A user on /r/nVidia has identified this according to the markings as certain Samsung LPDDR4 modules, 4GB at 25/GBs. Assuming this leak holds water, nVidia wasn't screwing around when they said it's a custom chip.
Basically, they took the Tegra X1 as a base, threw CUDA cores at it and did a die shrink of second gen Maxwell. Pascal at it's core is indeed a die shrink of Maxwell with improved memory bandwith and extra VR features, meaning that a Maxwell second gen die shrink would perform very similarly to Pascal (in terms of GFLOPs at least that is). It appears that since it mentions 516 cores for the CPU as well that it is indeed 512 CUDA cores and a quad core processor (indicating they got rid of the low power A53s in the original X1). What they're using for CPU cores is anyone's guess, though since it's based off the X1 it's most likely using A57s.
I'd still take this with a grain of salt, wait for someone with professional equipment to get their hands on one and take it apart and analyse the SoC with proffesional equipment to confirm the exact specs. Something that could potentially support this though is that the more recent document leak said that only developer kits have root access, and he stated that he had to use ARM_v8 (a developer protocol) to get the info, and if he's using the same version as the one dissassembled it's most certainly a retail version since the developer kit storage was said to be 64GB and the storage was 32GB from Toshiba in the teardown Switch.
