Th closest Nvidia alternative is the mobile GTX 1050, which is not released yet. It will perform very similar to the Pro 460, give or take few. I am basing this on the fact that the desktop GTX 1050 is only slightly faster than the desktop 460RX. The mobile GTX 1050 will be a binned, most likely underclocked desktop chip, while the mobile Pro 460 is a binned downclocked desktop 460RX with two extra EUs. It is even possible that the Radeon will outperform the GTX 1050 here, but we won't know before we see the actual benchmarks.
