Performance difference between Native and HDX

[jjnssn]

I currently have ProTools HD 10.2 with a Native card and an Omni and HD unit. I have had good luck and performance. Recently I have been running enough tracks, with Rtas plug-ins, sends, and automation that I am running up against the Native CPU limit.

What I am curious for those who have switched from native to HDX.

Are there any additional pro tools functions (non plug-in DSP) that are processed through the HDX card that are not processed as part of the Native card such that a person would see an improvement going to HDX from Native?
