What do all the AMD GPU sensor parameters mean?

[defffective]

I only started using HWInfo64 today on my Radeon 7800 XT and noticed a lot of sensor readings that I just didn't know of e.g. PPT, GPU SoC Current limit (%), etc. but couldn't really find any substantial explanations. Does anyone know where to find a list of documentation for these?

It's explained in tooltips when hovering mouse over.
