Benchmark Scene, Check your GPU power!

[adams]

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.

I don't understand how you get this time on OC 1070, 10-11 min is insane quick, I have a few questions:
what version of fstorm are you using?
What nvidia driver?
your basic system specs? CPU type and speed / windows version etc.

Mine with the same card/OC and I'm getting 12:37, I have strong system 5820k overclocked, fast ddr4 mem, ssd, win10pro 64x, max16 etc. There has to be a combination of must-do's to increase perf for GPU rendering, I learnt the hard way windows defender turned off is one of them. Any suggestions here would be good.

Edit: Want to also ask why GPU throttles down all the time, and does not use 100% GPU utilization at all it seems, usually 93-94% then throttles for second down to 60-70% tthen back up, this is not just with the 1070 happend with my 780 as well

http://www.fstormrender.ru/forum/for...=2676#post2676 I don't know gpu is running at 100% fullspeed.

[adams]

Ah OK so same spec more or less everything. In HWMonitor it shows throttling down to sometimes even 10% or so, never 100%. It must be something to do with Windows services running need to dig a bit more, I'm 100% convinced there is a must-do list to optimize windows/hardware performance for GPU rendering.

Fstorm 0.2.6a with driver 372.90, Windows 8.1, Max 2016

4:44 - 3x GTX 980Ti
6:54 - 2x GTX 980Ti
13:10 - Zotac GTX 980 Ti AMP! Extreme 1450Mhz
13:40 - Gigabyte GTX 980 Ti G1 Gaming 1380Mhz
14:20 - Gigabyte GTX 980 Ti G1 Gaming 1300Mhz

My system specs:
3x GTX 980Ti + 1x 660Ti (for display)
GA-Z87X-OC Force, i7 4770K, 32GB ram, SuperFlower 1600w

Everything is on factory clocks. The one gigabyte that gets hot drops clock to 1300Mhz. Everything is aircooled.

Power consumption drawn from the socket while the benchmark is running is 700w (Same as vrayRT).

* times I get from running Fstorm in RT

[RobSteady]

Yes, this is strange.

Karba, is FStorm already optimized for Cuda 8?

So it seems like the 1070 is the way to go (?)

[VFXCUBE]

Hope better optimization for GDDR5X mems.

My best benchmark was :
Fstorm 0.2.6e
Driver 372.90
2X1080 MSI OC 6:20
And 6:44 without OC.
Must stay waiting for an answer from Karba.

i got 3.00 with 4x titanx pascal fs 0.2.6a production and active shade both the same times lastest driver
4.06min with 4x980ti maxwell fs 0.2.4 production and 7.57 same config on activeshade


it's quite fast, however i was expecting a HUGE difference between the two generation..not only one minute

also 4xtitan is 20 secs faster than the 1070 but with almost the double of cuda cores and larger bandwidth, clock and whatnot

[Sylk]

OC or not OC? That is the question.

Previous bench, already in table: FSRv0.2.6a : my 2x GTX 570 Phantom, factory OC (core 750Mhz, mem 1950Mhz, voltage 1025mV) > 29.51 (RT and Prod)

New bench: FSRv0.2.6d : 2x GTX 570 Phantom, custom OC (core 910Mhz mem 2020Mhz, voltage 1150mV) > 26:33 (RT)

Interesting gain for me.


Next test after update FS to 0.2.6e, and drivers to 372.90.

EDIT:

Drivers 372.90
FStormRender v0.2.6e
2x GTX 570 Phantom, custom OC (core 910Mhz mem 2020Mhz, voltage 1150mV)

26min27s (RT)

- 6s

Any Corona users here? Would be interesting to see the FStorm benchmark scene in Corona.
Somebody feels like converting it?
Or can Karba provide it?

Gtx 1070 Gigabyte Founders edition: 13min30sec
Gtx 1070 Gigabyte Founders edition + Gtx 780 Evga Founders edition: 10min28sec

Both tests with 372.90 drivers/ Fstorm 0.2.6a/ Windows 10 x64

You can try to download it from here http://uploaded.net/file/kfmb23yh and test by yourself. Some Corona user from CG Talk has been able to convert the scene from Fstorm to Corona V1.3

Fstorm 0.2.6a

Karba, is FStorm already optimized for Cuda 8?

It uses cuda 8, but I didn't do any special optimization.

[wastzzz]

Gigabyte GTX 1070 G1

FStorm 0.2.0:

FStorm 0.2.6a:

0.2.6a is a bit slower: why?

[olivier]

7 min 11 sec with gtx1080+ gtx980ti
cheers

[m17a4y]

GTX 1080 not OC 12;39 , FS 0.2.6a , nvidia driver 372.90

A bit strange how a 1070 gets it faster?
