GPU benchmarks

[3LP]

Hey,

I know it's un-loyal competition but here is a nice bench chart

Do you think you could set something up like this for VrayRT, Vlado?

Would make it way easier to track.

Thanks

I wouldn't mind hosting a benchmark chart like this on MintViz Workshop, only if Chaos Group were to not do this of course.

We probably won't get to it anytime soon, so feel free

No worries I guess we would need two scenes now, one to test memory and one to test speed.

I think it's necessary to have multiple scenes that will work for multiple GPU types based on RAM. I would like to see different scenes for 1GB, 2GB, 3GB and 5GB. This should cover all the major cards I think. If we only have scenes that required 1GB then we're never going to be pushing Titans etc., similarly if we only have 1 or 2 scenes that are 3GB or so then older cards with small VRAM won't run the scenes at all.

[vlado]

So we got a Titan card to test; as has been posted somewhere else, it renders the benchmark scene in 1m 46s. Here are some other numbers:

GTX Titan: 1m 46s
GTX 580: 2m 39s
GTX 680: 3m 2s
GTX 690: 1m 31s

Vlado is it safe to assume that they will come up with similar config like gtx 690 for titan?

Heh how would I know

I've heard this is highly unlikely. More likely is a 7xx series, with dual GPU config. But those might fall back to 3GB/4GB RAM.

I'd say 2 x Titans is the way to go, if you can afford it!

I would say no, because GPU manufacturers are trying to stay within reasonable TDP envelopes with their cards.
590 was more than 350W, 690 is around 300W and Titan is around 250W. A dual Titan/K20 based card would be flirting with 450-500W TDP (usually dual-GPU cards are clocked lower, so consume a bit less - that's why 2x 680s > 1x 690).

450-500W would be at least 3x 8pin PCIe aux connectors, and nearly impossible to cool down with a 2 slot air-cooler. We had slower and much lower TDP fast Fermi GPU cards pushing high 90s or more under load, when even the extreme O/C CPU ppl go crazy with CPU temps above 85oC thinking those are too high.

Getting a 3x slot cooler design would be problematic in case fitting, and in the long run you would have to go to great lengths to cram more Titans in than you would with existing 2-slot designs. If you have this kind of patience and money, you can engineer a custom or modify a case and use flexible pcie risers/extenders to fit more than 4x titans that current motherboards can accommodate in an affordable 8-9 expansion slot mid or full tower. In theory you can get 6-7 of them on at least a couple X79 boards out there.

Some kinda dated 2P Xeon barebones from Tyan can do 8 dual slot cards for GPU computing. I believe the 2400W PSUs in those can support 8x titans (bit tight), as long as you don't do 100% CPU + 100% GPU utilization for prolonged time.

Thanks for the info. If GPU rendering was on par with regular rendering such thing may be worth investigating/investing in. But for me personally I won't bother getting gpu config until vray rt gpu is ready to handle all the aspects of our production and maybe, when it is, there are really good/reasonable cards available at that time.

Makes perfect sense...and I wouldn't be surprised if you saw your requirements start to crystalize in the next 12-48 months...

2x GeForce 580GTX 3Gb : 1min28s
1x GeForce 580GTX 3Gb : 2min44s
1x GeForce 680GTX 2Gb : 3min03s
1x GeForce 570GTX 1.26Gb : 3min12s
1x GeForce 470GTX 1.26Gb : 3min57s
1x GeForce 560Ti 1Gb : 4min50s

1x I7 920 : 60min40s



If someone can test one 670GTX, it could be nice, thank you !
I want to know if it's better to get a 690GTX or 2x 670GTX ??

Best regards...

2x 670 will be slightly slower, will consume slightly more power but you have the option for 4GB per card. 2x EVGA GTX 670 SC 4GB are cheaper than a 690 that is limited to 2GB per GPU.

If you want the maximum computation density, atm nothing is faster than a 690, but you will be limited for tasks that can fit in the 2GB buffer.

you want 670 here it is with CUDA engine:
Evga 670 GTX FTW 4GB : 3min6.4s

In this case my next GPU upgrade will be when cards will be able to pull times below 1 minute on this test
