Adding an old GFXcard for GPU rendering

Recommended Posts

Hey,

before messing inside my PC, I thought I'd ask here:

I have a old GTX580 sitting around, and a GTX980 in my PC. Could I use it to help on GPU rendering? (I'm testing RedShift).

Is there some step to follow in order to have it working as dual GPU rendering?

Is that 580 too old?

Is it worse it?

The 580GTX may offer some compute acceleration on simple scenes, but with only 1GB of vram you won't be able to render complex scenes. I would suggest that you simply use the 580GTX for your desktop monitor. Then you could dedicate all the vRAM on the 980GTX for single GPU rendering. Post this same question on the Redshift forum, they can give you the best answer.

Thanks Atom.

I naively thought it would just add some VRAM and compute power...

 

Wondering if the setting you propose (580 for display) is the right way, I'd loose the benefit of the 980 (viewport accl etc...), right ?

Or could I easily switch between the two, just before rendering ?

 

hmmm  I need to educate myself about those things... will investigate.

I would sell the 580 on ebay, and then use the $ toward even a lowly GTX 1060.

The 580 is going to be power hungry, slower, and have a rough time with pro apps with its 1GB VRAM. Houdini requires at least 2GB, and even that's cutting it close.
