i've recently been comparing the dozens of nvidia 2080 graphics cards currently on the market with an eye toward making an informed choice for a new editing workstation i'll be getting in the next month or two. over the past few weeks, i've learned about DLSS, ROP, TMU, CUDA, bandwidth, etc. now i know what all of these things mean, but i still don't really understand how they might be important to me. i.e., should i prioritise cards with more ROP's, more CUDA's, higher bandwidth, or ... ?
the system will be windows-based, and will primarily run adobe premiere and davinci resolve. in addition, i'll be using some AI-based image processors that depend on torch and tensorflow. i'm told having lots of CUDA's will be good for that -- but what about the rest ? do i care about texture-mapping units, raster operations, and such ?
note- i'm not really looking for advice like 'get card x' ; i'd really like to understand what importance these characteristics might having in my editing, if any [esp. rendering and filtering application times].
thanks much !

There should not be any difference beyond the amount of onboard ram, ram speed and gpu clock speed between the 2080's from various vendors; at most some may sell slightly overclocked versions, or perhaps one with some extra ram, but that's it.
You should also look at what the software vendor's recommend:
I can't see to find the recommendations for Resolve.
Having said this, I personally would not build or buy a x86 Windows based system for video editing.
I posted about this in another thread, the new Apply M1 Macs are beasts for video editing:
Warning, this video contains way more adverts than I usually like seeing in a Youtube video, or anywhere to be completely honest, but in this case it is worth it. What Apple has done with these ARM based M1's is very impressive, all the more so considering they just have 8Gb of shared unified ram. I would probably wait for a 16Gb variant, but even with 8Gb, at one point he compares that laptop to a 15 thousand dollar video editing Mac he bought and it's shocking to see that new Mac take the older expensive desktop to school.
Something to consider.
Edit, some more:
thanks much for the info, @sophisticles. i have to admit, that's pretty mind-blowing...
at first i was wondering how much of the performance might've been due to final cut, but then i watched the video w/davinci, and man...
unfortunately, i don't have much of a choice when it comes to the platform, i'm taking advantage of a special offer, and it's windoze-only. :/
but seeing those videos is really making me wonder whether i should forgo the offer i'm taking advantage of and get a mac !
thanks again for your post -- and for giving me something to chew on !
Sorry for butting in, but isn't the just recently released 3070 the better choice overal The benchmarks are quite higher than a 2080 and the price should be, compared to second hand 2080, pretty even. Unless there is an alternative use im not aware of, then just forget about my comment.
