Purchasing new card/s

[guitargodmiles]

I currently have a rtx2070 super

I would like to add additional cards to my setup and have been looking into purchasing an rtx2080ti or 2 rtxquadro4000.

From what basic research I have done, it appears that two rtx4000 will be better than an rtx2080ti?

I am leaning towards the rtx4000 currently but, I am open to suggestions if anyone thinks there is a more optimal setup.

Also, does Octane favor more Cuda cores or clock speed?

Thanks everyone!

I believe 2080ti's are more value for your money than the 2 quadro cards....

I know you are comparing RTX 4000 but I also was thinking about one RTX Quadra 6000 so threw that in.

RTX 2080ti approx 11GB Ram 4352 Cudas @ $1300 US (Double PCI slot wide sometimes 3 wide)
Quadra RTX 4000 8GB Ram 1792 Cudas @ $850 US (These are single wide I believe)
Quadra RTX 6000 24GB Ram 4608 Cudas @ $3,800 US (Not sure)

So you are getting more Cuda cores in one 2080ti and only one power draw (Octane Render loves more cuda cores) for less money.
Your scenes would have to be pretty large to gobble up 11GB ram especially with textures in Outer RAM. ( I am not sure if you can NV link Quadra RTX cards if not... you still only have 8Gigs if you can you can get 16GB)

You could get two 2080ti's for the price of one RTX 6000 run them in NV Link to get the 22GB memory (close) and almost twice the cores.

Not sure if all my fact s are correct... but my two cents worth... I look forward to what other users have to chip in and correct.

Quadro RTX 4000 is - 2304 CUDA cores (not 17xx) and 8 GB VRAM, it is basically same specs as RTX 2070 but with more expensive price tag being Quadro.

Thanks Lewis appreciate the correction.
Do you know why they are more expensive?
Do they have error correction, less power draw? Single lane etc?

What would be your take?

Thanks

Quadro should be Double precision (not used by Octane). Differnet drivers and better support but for our line of job with rendering not really importnat unless you go for more expensive models which have 16, 24 or more VRAM.

Quadro is kinda certified and better in some modes (like faster wireframe sorting or so) for Solidworks, Catia and similar engineering software so they can charge much more for those guys pretending it's "PRO" .

Thanks Lewis... that helps.

Do you know if Oxtane 2020 allows 2080s in SLI (NV Link I thinks its called now?)

yes Octane 2020 can use RTX NVLink, in pairs 1+1 GPU, so you can't NVlink 4 GPUs but you can 2 and 2.

Cool ... very useful
Thanks
