What are the differences between the P870(DM/DM2/DM3/KM/TM)?

What are the differences between the different models of the P870?

 

I'm looking to pick one up, it seems like it's just

 

P870DMx

     z170 Chipset

 

 

P870KM

     z270 Chipset

 

P870TM

     z370 Chipset

     Improved CPU Cooling Bracket

 

All of them seem to have the same case, keyboard, touchpad, IO, CPU(with BIOS mod), GPU and storage options.

 

Not 100% sure but all seem to be compatible 128GB RAM with some caveats(loss of Thunderbolt port) although 64gb would be more than plenty for me.

 

(Aside - Can you board swap this to a higher board, I.E. turn a DM2 into a TM with a motherboard swap?)

 

For reference, I'd be tossing an 8086k into it, and likely running Linux and Windows side by side. I'd be using 2 NVME drives, and would prefer to maintain thunderbolt compatibility if at all possible.

 

Am I missing any differences? Does the newer chipset actually offer a performance uplift or are they all pretty much equivalent.
