Comparison of features between Pure and Core

I want to try RetroArch with DOSbox and I was looking at Pure and [Core](https://github.com/realnc/dosbox-core). Is there somewhere a comparison between those two (and also with [DOSbox original in RetroArch](https://github.com/libretro/dosbox-libretro)...
