Leaks like this happen after every major Nvidia release like clockwork: A new GPU generation launches with high-end SKUs followed by specification leaks right before the inevitable launch of the mid-range SKUs. In this case, Pascal launched with only the pricey GTX 1060/1070/1080 options and now unconfirmed information has hit the web about the mid-range GTX 1050 GPU.
BenchLife has released a screenshot of the supposed GTX 1050 (GP107) with 768 unified shaders, 64 texture units, and 32 ROPS on a 128-bit memory bus. In comparison, the GTX 1060 carries 1280 unified shaders, 80 texture units, and 48 ROPS on a 192-bit memory bus. If current trends continue, then we expect the GTX 1050 to offer graphics performance somewhere in between the GTX 960M and 970M for 1080p30 gaming on Medium to High settings.
It remains to be seen if the notebook version of the GTX 1050 will be a 1:1 scaling of the desktop version. The GTX 1070, for example, runs at a slower clock rate on notebooks but with slightly more unified shaders and texture units to make up for the difference.
