Blender doesn't require sli for multi-gpu setups. Also, the appeal Of the 3090 is the massive amount of vram.

AFAIK blender doesn't treat two cards in sli as one card with double the memory, so you'd still be stuck with a 10gb scene complexity limit with two 3080s

even if it perform, AMD is late to party. there are several pro software already taking advantage of cuda GPGPU capability like, Ansys Fluent, Openfoam etc. it makes little or no sense for AMD card in pro systems as such.

Actually, you can run Blender with multiple GPU's without SLI mode. Plus, SLI slows down renders, so it's not recommended. The same applies with DAZ Studio.

Other more professional applications like Redshift poole the V-Ram of their cards using NV-Link. It is absolutely necessary for larger scenes.

doesn't blender work with different cards regardless of sli. People run mixed card systems all the time with blender.

Screw em. I bet AMD will let you link two cards together to kick a 3090's a** price/performance wise. Or they should if they are smart.

Initial benchmarks suggest that the GeForce RTX 3090 should outperform the RTX 3080 by up to 23.5% in professional applications, according to a new report. That is a far cry from the paltry 5% improvement in some gaming benchmarks, but two RTX 3080 cards would beat an RTX 3090 in professional applications if NVIDIA had enabled NVLink.
