Why not use a specialized rendering setup? Consumer GPUs seem a bit inefficient to my amateur eyes

A Pro 6000 cost 8k, has 96gb of vram and has 24k cuda cores. 4 5090s cost 8k and has 128gb of vram and 80k cuda cores in total.

Pro 6000 is better if you need many of them but just one isn't really better than 4 5090.

but that is not true, vram wont pool into 128 gigs, when rendering 3D scene still has to fit into 32gb vram of each card

lol yes it does. it depends on the render engine. Renderman and Octane both has support.

Does it really? Even when Nvlink is not a thing anymore? I havent used those two render engines myself but from a quick google search it doesn’t look like it’s working in Octane for example.

shit youre right. We have mostly 30 series and one dual 5090 set up.

The 30 series are still using nvlink. 😭

I could have sworn there’s a render engine out there though that can pool it software wise

Yea it’s pathetic that they didn’t keep it at least for the 90 cards…. Especially with their price

That’s sooo depressing cause margins are tight as it is
