probably yes. cinebench shows that they scale really well in this kind of scenario.
I'm on a i5-6500, 32GB right now and feel that the four cores are very limiting at times.
my minimum of opened programs at the same time is usually chrome (with many tabs), atom and rhino. chrome and atom for example are very good at multi-threading. very often more programs join in.
my initial plan was to upgrade to an i7 but with ryzen now I think/hope that my daily workflow will benefit much more from having 16 threads compared to just 4 or 8.
but threadripper would probably be overkill for me. I'm planing for ryzen 1700. cheap and I can still manage to fit the hardware into a compact and silent case.
interested to hear about your experiences.
