Performance comparsion of various GTX cards (including oc)

[mib2berlin]

The best single card atm. is the GTX 580, with 1.5 or 3 GB VRAM.
The GTX 600 series is not faster but more energy efficient, you get it with more VRAM (4 GB) but it is also more expensive.
GTX 600 series is also not full supported from Octane.
If 1.5 GB ok with you look for the GTX 590 3GB, it is a double GTX 580 with 1.5 GB VRAM each.
Keep in mind that mainboard, supply and case big enought to extend to 2 - 4 GTX 500 for more render power if you need.

A GTX 590 is about 3 times faster than your GTX 470 and you could use one card during setup and running both for final render.
No more lagging during setup.

Cheers, mib.

Is it actually 3x my 470? I am looking at the chart at the beginning of this thread and it shows a speed increase (Ms/sec) of less than 2.5x.

If people are getting 3x performance with a GTX 590, it is something I am very interested in. It only uses one PCI express slot right? if so, it would leave me more open to expanding a single computer rather than buying a second computer to assist in rendering. One thing I am wondering about is temperature, especially if I plan to expand to a second card.
Has anyone built a system with 2 590s? If so, what case did you use and how are you cooling it?

The scenes we are doing are fairly simple indoor scenes, so the 1.5 gigs of vram should be enough (I have had no problems with my 470)

Hi, sorry < 2.5 is more exact.
I only look short to the chart.
There are some user with a multi GTX 500 setup, I am shure you get the info you need.

Cheers, mib.

Tested the benchmark scene with the GTX 670 (Gigabyte GV-N670OC-2GD, factory overclocked)today .

I tested with Octane 2.58c (Kepler test build) and Nvidia 301.42 drivers; the test system had a Core i7 3770 3.4GHz, and 32GB RAM at 1600MHz.

The results:
DirectLighting 01:04 minutes 9.35 Ms/sec
Pathtracing 03:38 minutes 2.63 Ms/sec
PMC 04:41 minutes 2.05 Ms/sec

These are the numbers for a GTX680 (from EVGA, not overclocked) with NVIDIA driver 302.59.

Benchmark trench, all kernels have alpha shadows switched off.

DirectLighting: ∙ 9.18 Ms/sec
Pathtracing: ∙ ∙ ∙ 2.67 Ms/sec
PMC: ∙ ∙ ∙ ∙ ∙ ∙ ∙ ∙ ∙ 2.02 Ms/sec

What is the clock speed on your GTX 670?

does the maker of the video card matter? Will the EVGA be different than a ASUS?

[roeland]

I don't think it matters much, in the end all the GPU's come from NVIDIA. Different manufacturers may use different cooling, or they may have versions with more memory or a faster clock speed than the standard configuration.

Thank you, I was searching for these info!
One thing is not clear, why is a single 580 3GB better than a 590 3GB? Does Octane only sees 1.5GB if you use the 590? (because inside there are two 580 1.5GB)
Where the extra GB of memory come to help? Bigger resolution? More textures and more polygons?
If the main requirement is the speed, is the 590 the fastest single card I can get? (it looks like it from the chart)

One more question, just out of curiosity: assuming that money are not a problem, what is the fastest single card for octane ever? Quadro? Tesla? Or the 590 is still the fastest on the market?

Thank you!

Hi - I've just put in a 590

It works fine! All you have to do in enable the 2 gpu's under preferences in Octane, and if you find you've only got half the RAM - 738 or whatever, then you have to switch off the
'use multi GPU' in the 3d settings in the nVidia control panel -the Octane preferences also highlights this as 'dis-enable SLI'

a lot quieter than my 470 too!

The standaard Gigabyte GV-N670OC-2GD. So factory overclocked to Base clock: 980 MHz Boost clock: 1058 MHz.
