ok guys to the point. which best card choice for iray render . RTX 2080ti/2080 or GTX 1080ti ?
i want new card but... a bit confused with rtx ... some user say they cant use the RTX and some people can use it for render on daz.
thanks for repply....

I'm 99% sure everyone will say an RTX 2080ti, and I was planning on getting one too, but there's talk about a Super version coming out in the near future, as well as a 3080 series to be announced around the middle of next year (I think?). You *might* want to wait if you can.
That mean RTX 2080ti still better than GTX1080ti for iray render?
maybe i'll take this one MSI GEFORCE RTX 2080 TI VENTUS GP 11GB GDDR6...
i think i wont wait 3080series. i'll buy this RTX end of year or after christmas .
Daz 4.12 will work with RTX cards. The issue people are having is with the drivers. Windows has a bad habit of when it updates, it overwrites the gpu driver from the Nvidia one to windows default driver. You want the Nvidia driver. (there are debates on which, studio or game nvidia driver is bettter, imo, it really doesn't matter which).
From NVIDIA site:
All NVIDIA drivers provide full features and application support for top games and creative applications.
If you are a gamer who prioritizes day of launch support for the latest games, patches, and DLCs, choose Game Ready Drivers.
If you are a content creator who prioritizes stability and quality for creative workflows including video editing, animation, photography, graphic design, and livestreaming, choose NVIDIA Studio Driver.
If you are both a gamer and creator, choose Game Ready Drivers.
i believe 430.86 is the earliest driver you need to work on RTX cards. The most recent driver is not necessarily the best.to use. Personally, I keep the latest one that works on my machine and I'll update when i'm sure a newer version is stable with Daz. (I'm fortunate i have a machine solely for rendering).
As for best GPU to buy, smarter folks than me will have a better opinion. From what I understand, CUDA cores will detemine how fast your render goes. VRAM will determine how big a scene will fit before render falls to CPU. (they don't combine, so 2x4-GB cards is still 4GB scene size).
Most analysis of cards will quote #% more cores for $# more and you can get a comparison of how much cost for how much improvement.
That is all just basic info. Different generations of cards use different cores, etc. etc.
I use a 2080ti, I got it primarily for the VRAM amount. The cost per % increase in speed (per CUDA cores) was probably not worth it, but to me the extra VRAM was.
Hope I answered at least part of your question.
Difine best.
They all produce the same image.
You are paying for RAM and speed.
There wont be a super 2080ti, as it already uses better dies etc that has resulted in the introduction of super for lower tiers.
The upgrade to the 2080ti is a Titan.
An RTX2080 isn't just better than a 1080Ti for iray rendering. It's *way* better than a 1080Ti, like, 60 to 80 (for the RTX 2080Ti) percent better than a 1080Ti.
Benchmark thread
Well I'm looking at about a dozen tech websites that say a 2080ti Super is planned for release in the first quarter of 2020, but I guess you never know.
There's always something coming around the bend.
Lots of tech sites quote each other. No 2080ti super cards have been registered with any of the offcies that require that before such could be releaesed (EU). Nvidia would have released it for Xmas rather than waiting into 2020 where it will be pushing up against the Ampere release. I think it is safe to bet there won't be such a card.
Very possible, we'll just have to see.
On a related topic, assuming there won't be a Super and someone decides to buy soon, is there much of a difference between the various editions of 2080tis for rendering use? I don't want one that's overclocked, and the only real differences I've seen is that some editions have a third fan. Does anyone have any opinions on which versions, if any, would be worth paying a little more for and if there's any to avoid?
Having upgraded from three 1080ti's to two 20180ti's, I can tell you the 2080ti kick's the 1080ti's [redacted].
For iray rendering, there's practically no difference in performance between different brands of the same card model. A card with additional cooling might be interesting if you happen to live in a very hot climate and suffer from an unreliable airco system, but that's about it.
Somehow, iray rendering doesn't push a graphics card as heavily as gaming does. It's more constant, without any of the performance spikes you'll see when gaming. If you track the heat of a graphics card during a gaming session, you'll see it fluctuate constantly, between 60 and 100 degrees Celsius. You'll also constantly see or hear the fans speed up and slow down to compensate. When rendering in iray, the heat doesn't spike as much, but stays more between 70 and 80 degrees Celsius, and the fans rotate at a fairly constant speed as well. Game performance depends on whatever happens to be on the screen at a specific moment. Rendering depends on the fairly constant size of the chunks of data the GPU has to handle.
You also cannot use gaming benchmarks as a guide, or really any other benchmarks. Iray is different, and the RTX cards get a real boost with it now that Iray can take full advantage of the RT cores they have. Your best source really is the benchmark thread that was linked here. I also keep that bench thread in my sig so anybody can see it from my posts (assuming they have signatures turned on).
Right now, the 2080ti is the undisputed Iray king. Only the Titan RTX is faster, and it is only slightly faster at that, but it also costs twice as much. Though it does offer a lot more VRAM, which is its biggest benefit. VRAM should be a consideration. The 2080 Super is a great card as well, faster than the 1080ti, but it only has 8 GB of VRAM. So that is something to consider.
Of course that all depends on the size of the scenes you make. But the 2080ti is the fastest mainstream card and also has the most VRAM with 11 GB.
There is not much of a difference between different models of the 2080ti. Some may be clocked higher, which can cut a little time off long renders, but nothing too drastic. The main concern is how capable the cooler is, and also if the card will physically fit in your case. Don't forget to check that! Nothing sucks more than to buy a fancy new card only to find out it is a monster that wont fit in your case. The 2080ti is a high performance card, so it generates a lot more heat and thus some of the versions may have wild heat sinks on them.
Size is also a factor if you plan on ever using multiple GPUs, you need them to fit.
Considerations I'd make in buying a 2080ti:
Length, width and height of the card. You do not want to buya card and find you can't get it into your case, or find you can't put the side panel back on or that other cards no longer fit.
Number of PCIE power connectors. You don't want to get a card with 2 8 pins when your PSU only provides 1.
Cost and reviews. I'd get the cheapest card with decent reviews on sites I trust (not Amazon).
Brand. I wouldn't worry about Gigabyte, EVGA or any of the brands commonly for sale in the US but the ones you can find on AliExpress? No thanks.
Thanks, I guess I already knew all of that but wanted to hear what owners of the card had to say and maybe they could help the OP with his decision. I have a giant case with good air flow, but I'll be sure to check the measurements and power connectors before buying anything that expensive.
Kenshaw, if you don't trust Amazon, what sites would you trust? I mean I would buy one directly through nVidia if the price was right, but I've never had problems with Amazon. Newegg actually seems to have more issues these days than they used to, and I ordered my current 980ti from a camera shop in New York a few years ago and never had any problems at all.
