Please note that this post is tagged as a rumor.
While GTX 1080M is still few weeks away, notebook manufactures are already adjusting their new systems for best performance with new Pascal GeForce cards.
NVIDIA GeForce GTX 1080M 2048 CUDA Cores
According to the leak from Chiphell, GTX 1080 might feature 2048 CUDA cores, 128 TUs and 64 ROPs. At least that’s what we can read from ultra-low resolution pictures that were posted there. We tried to enhance the quality with our CSI tools, but it didn’t help much.
The leaker revealed that GPU clock speeds are 1442 MHz (base) and 1645 MHz (boost). Not a word about memory clock, but we expect something close to 2000 MHz.
The Fire Strike score is quite readable though, we can assume that GTX 1080M gets 16893 GPU points. This would put GTX 1080M to the top of single-GPU notebook performance.
Later in this post you can find GPU-Z screenshots resized with two different techniques. Take following specs with a grain of salt:

This is my attempt to read GPU-Z data from this tiny picture.
