Is One 3090 Better than Two 1080 Ti's for Iray?

I'm currently running dual 1080 Ti's and may be in the market for a 3090 now that prices have dropped.
EDIT: Upgrade complete. First impression: WOW!!!! Details in yesterday's follow-up post below. :D

one 3090 is similar to two 2080ti... so the answer is yes.
You will be quite happy with a 3090.
I went from 1080TI -> Titan RTX -> 3090, and each one was a major leap. However, the leap between Titan RTX, which is already super powerful, was like night and day. Rendering with this beast is fast and I find few things take over 15 minutes to render, even with multiple subdivided character and refractive surfaces.
The 24GB of video RAM is my favorite thing about 3090 and the reason I want to get one still. I don't know how render speeds will be affected between the two, but more complex scenes can be rendered on a 3090.
Also, the 1080ti doesn't have ray tracing capabilities, if I'm not mistaken, so right there alone the 3090 is a much better option if we forget the amount of cuda cores and the VRAM in the card itself.
Trigger pulled. ASUS ROG STRIX Gaming 3090 for $1750, sold and shipped by Amazon. That's a near $1500 drop from scalper prices I read about a year ago and $250 below MSRP. No telling how long it'll last.

You won't regret it. I was initially skeptical jumping from the Titan RTX to the 3090 when I was debating buying it, but that disappeared the same day I installed it. I imagine it will be even more impressive coming from 1080ti's, even if it's double 1080's.
I sure wish Nvidia would make like a 3070 with 16gb/24gb ram.
It will be interesting to see how the 40XX series plays out....
Yes, I went from two 1080Ti to a 3080Ti...
Steve.
It's waaaaaaaaay better, you'll be glad you did. I forget now, but I had both Titan Xp and 1080 Ti - I forget if it was approx. 4x or 8x faster.
Are we able to get 3090s shipped before the archeologists of 2048 find our dusty, mummified corpses?
Card's here, installed, and working beautifully. I've already uttered quite a few explatives in amazement of how fast this thing is. I benchmarked one of my projects last night and it took my 1080's 32 min to render it in 4K. My new 3090 did it in 15min. The Viewport's Iray mode is unbelievably smooth when navigating scenes, so much more than it has ever been.
Coupled with my Ryzen 9 5900X and 64 GB RAM, I believe I'm pretty well set for at least the next 10 years. :)
EDIT: BTW, I'm using DS 4.15.
Nice! Enjoy the card. I would upgrade my card, but I'm waiting to do the complete PC build for that.
Thanks!
I upgraded my PC last October. My 1080 Ti's and three SSD's were the only components I brought into my new setup. I decided to wait for a GPU uprade until I could double the VRAM.
I'm especially happy to be back to a one-card setup. I've always felt annoyed that the 11 GB on my second 1080 was never used. I am never going dual 3090's. 24 GB is too much VRAM to throw away.
That is the thing if I remember right only Nvidia's Quadro cards allowed memory pooling, for such applications that made use of the feature.. I myself went from a 1070ti to a 3060, the main reason I went for a 3060 is the vram and the main reason is that the 3090's, are over $3k AUD..
But yes you will be very happy with that new card..
It's better than 10 x 1080TIs.
Due to the RAM, but that is my opinion as many might not reach the RAM cap on a single 1080TI.
I often use well over 11GB.
Two 3096 will give you 48 GB of VRAM! The 3090 is one of the very few video cards that can share its VRAM between two cards. However, if would require quite a special motherboard, a huge amount of system RAM, and an atomic PSU to handle all them both.
Still needs the NVLink, otherwise you get no more than 24GB's.
GPU's with NVLink connectors are 2070Super, 2080 and 3090
That's nice...
Never going to happen.
And the A4500 and higher.
Currently the sentient cockroaches that will inherit the earth, will most like have a better chance of receiving them than most of us.
Sadly, the roaches will just use them for crypto mining instead of anything useful.
Well at least they're not challenging us to computer chess or majong. Yet.
Serious question, though. How long might it take for me to get a 3090 TI in hand if I placed an order this weekend?
Depend where you are I suppose but in the UK It's Sunday dinnertime and I could have my pick of about half a dozen different models delivered tomorrow.
Glad to hear you pulled the trigger and are happy with it. This really feels like the first card that makes rendering in iray how I hoped it would be years ago.
The funny part is how quickly your tolerance for waiting goes down with it. If I have a scene that takes longer than 15 minutes are start looking to see what's slowing the render down
