Boost Clock for 3d modeling / CUDA rendering

[nowikovs12]

Hi there, 

 

I am considering to buy GTX 1080ti for my existing machine. Currently I have a 2GB GTX 680, and it has been really good and keeping up with most of the tasks. 

 

Question: I am looking online and there are cards with different base clock speeds, which, I understand the higher - the faster performance. However, how much of a difference does it make when modeling heavy 3D scenes (dense in geometry/shading)? 

 

Also, does it have any effect on CUDA rendering (speed)?

 

As always, thanks to everyone.

no difference with the base clocks at all,they all boost into the 1900's anyways

Long Answer: 

to answer this in a professional way we should know how the algorithm works and take a few hints on how it scales.

Usually clock increments scales linearly, assuming there is no bottleneck elsewhere. This assumption is quite expensive in terms of giving a proper answer. The particular software modeling you are using with the particular flags you are using could be in a resource shortage elsewhere, before it hits the max clock roof. ie: VRAM. Hence you'd see no performane boost (which is totally the case in most mainstream GPUs with pro-hardware since, clock favors rapid data output burst, while rendering pro software prefer accuracy.

Short Answer: Doesn't matter much since you can overclock any 1080Ti to reach within 5% any other 1080Ti clock level.
