As per the resolve config guide, the d700 / 12-core MacPro, can get it done. Particularly with none raw formats, like prores 4K files. OTOH, those would likely not perform as well and be more troublesome on a windows system. But as per the resolve config guide, something like a 24-core z840 with a few Titans/cubix, would certainly fare extremely well with most raw formats, including red, sony, alexa. But not particularly well with quicktimes. Linux can be configured to do well with all of them, but is MUCH more expensive. There’s also a resolve config guide for linux as well… I think my point here is that these and many other questions have been helpfully answered for you, in the Resolve Config guide.
