Totally unscientific 1080 vs 1070 benchmark

[ron908]

So, since I just had both a 1080 and a 1070 in my machine, I thought I'd try them both on the octane benchmark scene.

I just opened the benchmark scene 2.17 in the 3.02 standalone demo and looked at the Ms/s results

Windows 10, nvidia driver 372.54

All measurements after ca. 1 minute render time

There was surprisingly little difference between the 1080 and 1070. The 1070 however is slightly overclocked by default, while the 1080 was a stock founders edition. Still, at 40% extra cost, I barely got something like 10% extra render power from the 1080. But take this with a grain of salt of course...

Thanks for results. IMO comparing same technology GPUs is rather obvious - cuda cores, core clock and memory matters. If you could post results for older gpu would be useful. OctaneBench still does not support Pascals.

Well the reason I posted it was because I was surprised how little difference there was between the two cards, seeing as how in gaming benchmarks the 1080 is sometimes almost always _significantly_ faster than the 1070, whereas here it is barely 10-20%.

A colleague ran the same benchmark on his (oc'd) 980TI and those were his results:
Idea Scene:
Info: 93
DL: 23,5
PT: 21,5
PMT: 5,7

Not the same machine underneath of course, but still, it gives a good impression that at _this_ point in time, if you need render power right now, the 980 Ti are still the way to go. Especially taking their price into account.

Thank you for the scores - very informative. We need full Pascal suport/full speed.
