GTX 580 vs GTX 1070 or 1080

Hi,

I'm waiting and waiting for some official benchmark score for GTX 1070 and and 1080 and after many months there is nothing in octanebench website. Can someone please tall me how big progress I will get if I will change my old GTX580 graphic for 1070 or 1080.

I'd like to know this aswell, trying to decide between 1070s and 1080s...

I think this has already been answered. When the issues with CUDA 8 are fixed OTOY can move forward in that area. At the moment it's a mix between CUDA 7.5 and 8 just to get it working.

That's a big disappointment. After more than half year the problem is not solved. Maybe Nvidia doesn't see future in GPU rendering?

1080 is faster than 1070

I'm currently waiting for my parts to come for a duel 1080 build upgradable to 4.

This guy seems so have no trouble, are there any problems with Cuda on Pascal cards or is it just the lack of benchmarking that Otoy haven't updated?

GTX 10-series runs fine in Octane with the mixed cuda 7.5 and 8. There's just no official benchmark as Nvidia still needs to address the cuda 8 problems OTOY are having.

You can still test the GTX 10-series in an unofficial benchmark here:

... and compare with GTX from https://render.otoy.com/octanebench/res ... ingleGPU=1

GTX 1080 is 25-30% faster than 1070 but cost double, it is like Formula 1, a lot of money for a small gap.

Yep, lots of things to take into account. Next month we will properly see GTX 1080 Ti be announced which might change peoples minds again

There is nothing to take into account, if one is a professional artist, that works with deadlines, and values their time...

More than a couple times now, I have seen posts where folks seem to weigh the costs of more powerful GPUs as if it were a one-time proposition. If GPU X is 20% faster than GPU Y, it would be 20% faster every single time you render.. anything. Once you multiply that difference times your average weekly renders, the additional cost of a better GPU is negligible.

And this is coming from a guy that used to be one of the biggest effing cheapskates on these Octane forums. Brothers and sisters, I have seen the light. My GPUs have quickly paid for themselves, in my eyes. So I would never, ever consider getting anything less than xx80Ti, or in this case, a 1080 over 1070, if the decisions had to be between those two... but personally would absolutely wait for 1080Ti, if I could.

But hey, if you are a student or a hobbyist, then there is nothing wrong, at all, with a 1070, or hell, even a 1060. smicha even seems to like 1070s. I am strictly speaking from a viewpoint of one who deals with deadlines. And I don't want to see anyone rue the day they bought a 1070, because it did not allow them to meet a deadline, or every time they render they find themselves wishing they had that extra juice.
