Prebuilt with 3090 under $4,000? 3070 not enough vram.

[TheNuzziNuzz]

Hey guys, I do extreme blender (3D cad) work. I managed to get a MSI 3070 for retail! However, i've been having issues with running out of vram. I've concluded that is only a matter of time before, out of frustration, I pay a scalper $3,000 for a 3090. I've found a prebuilt system with a 3090 for $4,100, latest i7 and everything else you would expect. Then I plan on selling my current rig, of which the 3070 seems that it will get about $1,400 so my wallet doesn't hurt quite so bad.

 

I'd love any suggestions anyone has to tackle this situation. It's really too bad they don't have NVlink on the 3080, because two 3080s would get me 20gb of vram, and almost double the performance of a 3090 (since blender scales 100% across multiple GPUs)

 

Thank you guys!

no , it only combines gpu power not vram

you are rendering the same image with two gpu's , thus .... the same information has to be in both gpu's vram to render the same image

Ever considered a RX 6800? Or even better a Radeon 7 second hand if those still exist. CAD likes OpenCL more than CUDA any ways so you'd be getting 16gb of fast VRAM and likely on pair rendering performance as the 3090 thanks to this GPU architecture/drivers peculiarities.

Actually it is very the opposite. The work I do in blender uses Optix. My 3070 is able to more than quadrupple the speeds of a 6700XT.

 

Here, check this comparison out: https://opendata.blender.org/

 

As you can see, AMD doesn't even place on the top 10 fastest GPUs.

Not with NVlink. Blender & NVlink actually bridge the memory across two GPUs adding it together. I was saying how unfortunate it is that nvlink is not on the 3080.
