Choosing between the 125H and the 7640U

Hey o/

I'll be purchasing a framework 13 soon, but I'm having some trouble finding direct comparisons between both configurations. Efficiency is a priority for me, and raw performance isn't a huge concern since anything intensive would be offloaded to my desktop.

I'll be running NixOS (Linux) and using it for general browsing, programming and some light CAD work. I'll also be streaming from my desktop quite a bit, so whichever decodes video more efficiently would be preferred.

[ EDIT ] : Opted to go with the 7640U. Thanks for the replies!
