GTX 1080ti (or RTX 2080ti) vs GTX 1060 - viewport performance, any test??

[baastyan]

Did anyone do any tests comparing viewport performance GTX 1080ti (or RTX 2080ti) vs GTX 1060 ??
I have 1080it in my main WS and I am planning to buy GPU for new rig. No GPU rendering, so only viewport perfomance matters.
As we all know the high-end GPUs absolutely do not guarantee great viewport performance. It is more 3DS max matter. .. but I guess there is still a difference between 1080ti and 1060. The only question is how big this difference in performance is? Will I notice it?

We are working on arhviz at the office. So scenes might get really big:
polly count up to 100-150 mln poly,
file size up too: 2GB
Xrefs: YES
external files count: up to 1000 files, a lot of proxies
external files total size: up to 5GB
Memory usage (before I press RENDER) up too: 40 GB

Below one of our heaviest file. A lot of interior stuff (that you can not see on the screenshot) makes this scene really, really heavy. As you can see the scene used all memory (11GB) and FPS score is just great: 2,17 ... So 1060 will be more sluggish with "only" 6GB of memory??

you could significantly speed that up and lower the memory usage by turning edged faces off and dropping the viewport texture resolution. you're right that a 1060 would choke as is, but with those tweaks you could make it faster than what you're currently getting.
I dont think a 2080ti would be much of a jump from a 1080ti, if you already have a 1080ti i'd skip this generation

With this kind of scenes you should go for a 1080ti and it is a great value compared to 2080ti
in the screenshot above you barely did fit your scene into VRAM
