PBM - also the P6 noise node has 2 nodes - the "original" and the "improved" - so if you use improved - it will be different from the P5 noise node. byAnton - from what I can tell (based on lots of renders using node based skin noise), a full body render at 900x900 needs a Min Shading rate at about 0.5 (any less give no noticeable improvement). For a head portrait at the same dimensions, 0.2 seems to be the right mark. 0.0 Min Shading Rate is required if you do larger renders (2000x2000).
