New 2080 ti or Titan video card

I am debating getting a new system with one of these cards, the Titan seems more powerful but less common maybe because of price? Any sugestions which one I should save up for?

The Titan also has more VRAM... you will need that for high assets scenes.
..assuming it's a Titan RTX
The 2080ti and Titan RTX are roughly comparable in pure rendering performance. The major difference is the Titan has 24Gb of VRAM compared to the 11 on the 2080ti. If you want to do crowd scenes you would want the Titan otherwise the 2080ti is fine.
...the RTX Titan also allows for operating in Tesla Compute Cluster (TCC) mode that disables Windows WDDM, and can take advantage of NVLInk for memory pooling as well.. So far as I understand though, only Vray supports VRAM stacking.
Thanks for the input I think i will save a little longer and go for the titan
The current DS beta says it supports NVLink VRAM pooling but I haven't seen that anyone has tested this.
Why disabling Windows WDDM is important, if you are using Windows 10, is that Windows charges a 19% (90% of 90% left available) 'VRAM Tax' on most graphics cards. It used to set aside a much smaller amount for Windows, say in Windows 8, but since it's now a percentage, well the more VRAM you have the more you lose to this silliness. Despite multiple complaints, Microsoft has expressed exactly zero interest in rectifying this injustice.
The card in question needs to be able to support this 'disabling' feature though, and 2080 Ti's aren't 'professional' enough for Nvidia to include said feature as I understand.
The RTX 3090 Ti is most likely going to be out this summer. If not summer, this year for sure.
Rumored specs: 4992 CUDA cores with 12 GB GDDR6 VRAM @ 18 Gbps. Also rumored to be about 40% increase over RTX 2080 Ti.
Might be worth waiting a couple months.
....yes but will it allow switching to TCC mode? So far that isn't a feature of GeForce GPUs or the drivers for them..
The Titan isn't all that much faster than the 2080ti, unless your scenes don't fit in the 2080's 11 gigs. If 11 gigs is sufficient, instead of the Titan, get two 2080tis :)
..why I'm still using w7 Pro as its "footprint" is almost negligible. I have a Maxwell Titan X but haven't tried to set it in TCC mode (really don't need to with W7) because it overrides the fan control software.
From what I've read NVLink with Vram pooling is now supported in Daz Iray as well.
This should mean you get 22 GB with 2 2080 TIs and better performance for less money.
If you can wait, seeing what the 3000s series offer might be worth it as it is rumoured they will have more VRAM.
I hope that the Raytracing cores of the 30xx series will be faster than those of the 20xx series. The Raytracing capabilities of the 20xx series were not really up to what Nvidia promised, in gaming it really shows. Rendering can benefit greatly from Raytracing too depending on your scene - I render a lot of geometry heavy scenes and raytracing really helps. Let's hope Nvidia improves here.
That's probably the best advice: if you can, wait.
There are a LOT of changes coming, not only is NVidia relatively close to a refresh, but the Vulkan API is finalized, which would eventually make Navi X2 more relevant to Daz users. We all know what Ryzen/Threadripper CPUs did to Intel's pricing LITERALLY overnight...
Thanks for the advice everyone, I think I will wait to see what the 3000 series brings
I'd go for the Titan.
11GB isn't that much RAM, expecially as you lose some to Windows10.
You can configure to to not lose any with an RTX Titan, I believe.
I'd actually saved for a Titan, then decided to move house, and spent the cash for the Titan and more on the move. Saving up again. lol
I'll probably wait for the next release; kinda weird really, as I was originally saving for the 1080ti.
Ampere will not release this summer. Nvidia generally release cards 6 months or so after the announcement. Ampere is not yet announced and the shutdown in China shut down all GPU production. Even if FE cards were in productioon, there is no indication of such, they are now delayed 2+ months.
All specs right now are wildly made up. What could be roughly predicted by the increases in CUDA across generations is
980ti 2816
1080ti 3584 (27.3% increase)
2080ti 4352 (21.4%)
3080ti 5412 (24.35% average)
For VRAM there is no point in a 1Gb increase and there is no way Nvidia can sell cards for what some of the numbers floating around would cost. I'm guessing 15 or 16 or no increase at all.
People should not wait for Ampere until it is at least officially announced.
No. You will lose VRAM, it isn't all that much a few frame buffers, unless the card is put into TCC which means you cannot use it for a monitor.
...that would be fine by me.

From what I read from different articles I now believe that official release information will be around August as the article suggests.
Regarding performance it's hard to believe the 70% increase in performance but on the other hand, we are seeing hardware advancement from the new 7nm arhitecture. Such an advancement usually comes with higher performance increase over the last generation.
About the more VRAM, it's anyones guess. I think we will not see a real increase there unless ATI does so as well pushing the barrier forward.
Whichever is the case I still believe VRAM pooling from 2 cards is a lot better than the overexpensive Titan.
I've no intentions of using it for a monitor. I'll probably use the 980ti I currently render on for that. This 970 I currently use for the 3 monitors is getting long in the tooth, and showing signs of wear.
Windows reserves memory for the dispalys that could be connected, not the dsplays that are connected (I gather, because otherwise connecting a monitor would cause a crash).
...unless it's an RTX Titan, or Quadro,. Then you can use TCC mode to disable WDDM.
