I wonder, how does a GTX1080 compare to a really high end CPU in case of Cycles rendering? Like, the threadripper, or some 1000 dollar Intel CPU or something like that…
Does CUDA make it a lot faster still?..
With 1000$ you can buy 2x1070ti which are going to be faster in rendering than any cpu of this price range
sure, if you render simple scene with simple stuff - must fit in VRAM and shouldn’t use lots of volumetrics, SSS…
Blenders own testing, granted, about 1 year old. so 2.79b is slightly faster that that build. luckily since then 2.79 didn’t have drastic improvements, at least in official build.

Overall, a 1080Ti is about 90-95% that of Intel Xeon E5-2699 v4 (22c44t)
So definitely GPU’s are much smarter investment (cost/perforamnce) Though there are cases where Blender is not GPU compute capapble like texture baking i think and few other major funcitons.
So always go for balance.

This also means you can forget about using the experimental microdisplacement at high detail levels (2.8 has a big memory optimization, but using it for the whole scene would usually need more than 8 gigs of memory).
