All big three hardware encoders info is available from their own published SDKs.

For instance:
Info on Lookahead, Spatial AQ, Temporal AQ, 10bit encoding can be found at Chapter 8 of https://developer.nvidia.com/nvenc-programming-guide

Some info on nvidia two-pass and other rate control:

Nvidia NVENC architecture back in kepler day.

EDIT: I am still waiting for nvidia new nvenc hardware revision for proper HEVC B-frames. I mean, back in 2015, nvidia said HEVC B-frame support was in their roadmap.....

With Pascal.....nvidia had implemented motion estimation only, SAO, 10bit encode, lossless, new rate control, 8K, AQ
Missing part --> 12bit HEVC encoding and HEVC B-frames.
I wish for b-pyramid support too.......
