Question / Help Dedicated stream machine for NDI 4K/60fps

[Roman Ten]

Hello everyone, there is so little information about NVENC performance on different cards, so i'm just confused for a long time. As wiki says i need Nvidia GTX10xx for sure, as it doubles the encoding performance of 4K H.264 & HEVC, when compared to previous generation NVENC. But there is no full info about specific model, only what i found is the GP107(1050/ti), GP106(1060 3gb), GP104(1060 6gb) have 1 nvenc chips, but GP104(Quadro P5000) have 2 chips ... But as i found not every of these have the same performance. It directly connected with GPU and GDDR performance. So my question is - GTX 1050 (not ti) will be enough for 4k 60p stream ?
