hi all: I have a question,gtx680 and gtx580 which one is faster in octanerender?
thanks.

Hi zhangyufeng,

For OctaneRender the 580 is faster (depending on the scene the 680 can be around 10-20% slower), however the 680's have the benefit of using less power, they have a higher maximum VRAM and also in coming releases they will have a higher maximum texture limit.

(this is using test release 3.03)

Cheers
Chris.

ok,thanks.

Some scores attached. I'll post OC GTX 680 watercooled soon.

I can found GTX580 for 200€ these days but I dont understand is there any differnce between the manufactured models (PALIT,MSI,GAINWRADS, eVGA, ZOTAC) ?
Would you say that the ratio money/speed makes this card to be the best buy?
Only thing I see lot of people are complaining is 1,5GB ram.
How big scenes are we talking aboth?
Can you render s simple architectual interior (living room, with sofas, tv, objects)?

a. Difference: there is a difference in those manufacturers. As a rule of thumb (for me) its always Palit since their cards are reliably overclocked by default with a low noise vent.
b. 580 is faster for octane than 680
c. RAM needed really depends on polys and texture images. Even simple interiors but with high detail textures and structures on a Hi-Res render can take loads of RAM. So it all depends on render size, texture and (unique) polys.
d. Generally you can render simple scenes,yet what is simple to you might be complex to others. Considering todays pricing you should imho either go for a GTX 580 or GTX 780

Hope that helps.

About to purchase Octane for Rhino. Running both through Bootcamp.
I currently do not have a nVidia/CUDA card and looking at the 680 for Mac. . .

A couple of nuub questions:

If a single card is not enough power I should be able to just add another 680 for Mac right?
Would I then need additional power support for MacPro 5,1?

I currently have a Radeon card driving my Apple 27" display. Can I continue to use that card for display and connect nothing to the 680??

Thanks for any guidance on this

Heretic thanx for the information
Any thoughts on the GTX660i maybe?
