Benchmark Scene, Check your GPU power!

[deC9r]

My 1070 runs at stock which is app. 1500/4000mhz 13-14mins and oced 2100/4400mhz around 10-11mins.
There is something limiting the 1080, probably it's a combination of gpu clockspeed and the new vram controller for GDDR5X.

[antonyebl]

doesn't make sense relative to CUDA cores count, even if one disregards slightly higher base clock speed of gtx1080;

4x 2560 cores (gtx1080)
vs
4x 1960 cores (gtx1070)

in those terms 1080 should be ~1.3x faster (which +- holds for single 1080 vs 1070 i.e. 13min vs 11min >> ~1.2x)

just ran the benchmark again with the 0.2.6e, stock gpu clock @1531Mhz but while rendering card auto-boosts to 1898Mhz, time about the same as with previous benchmarked release (~13min)

Shows on multi gpu setup something bottle necks system hardware or code loses efficiency or both, as no real change 1070 vs 1080 multi GPU speed times.
1 gpu I reduce render time by nearly 1.5m by OC.
Would be interesting experiment see where the point of diminishing returns is, eg. Someone with multiple gpu sysytem, test time 1 gpu OC and no OC, then 2 the same , then 3 same ,then 4 same.

4 x 1080 = 8GB = 3160 € = 3:13
4 x 1070 = 8GB = 2000 € = 3:25

mmhhh...

very strange, not possible

[Karba]

4 x 1080 = 8GB = 3160 € = 3:13
4 x 1070 = 8GB = 2000 € = 3:25

mmhhh...

Yes, this is strange.

[RobSteady]

4 x 1080 = 8GB = 3160 € = 3:13
4 x 1070 = 8GB = 2000 € = 3:25

mmhhh...

OC is clearly useless. It just eat up your GPU.

3:13
4xGTX1080s Power limit 120%

3:11
4XGTX1080s Power limit 120% + core clock 200Mhz

EVGA GTX1070 FTW (2138mhz core, 4398mhz mem)
FStormRender v0.2.6a

The table times column should be relevant to a version number of FStormRender as a lot of variation version number to render speed.

[RobSteady]

05:36

FStorm 0.2.6e
2 x 980Ti + 1 x Titan Z

This version seems to be a little bit slower than previous ones (05:11).

What the meaning of the gray lines in table ?

Edit: oh ok i see, gray for multiGPU.

[igen]

I know my table not real right to compare until stable but at least I can more easier to make decision which VGA I will choose for upgrade

2x GTX 1070 still more faster then 2x GTX 1080??

[Sylk]

don't show any table :/

Edit: about igen post

Benchmark results has been transferred into the table. Please, have a look at the first page.

Thanks for the table !
Hmm my GTX970's 16:45 yesterday test (oc to 110%) is faster than 2xGTX780, good to know even with that nasty 3Go vram limit.
I guess I'll go for the GTX1070 cause 1060 is just not worth it at least for me.

Benchmark results have been transferred into the table. We collected all results since August 1. We didn't use results until that date due to constant speed improvements. Please, have a look at the first page.
