So, nVidia just announced the 50-series last night at CES. Huge push on it's AI capabilities. They glossed over performance specs of it, but here's what I'm guessing:
In Daz, performance-wise, you won't see a significant gain over a 4090 or even a 3090. Renders may complete quicker, but only by a matter of seconds and not minutes. One boost I can see to it would be with the iRay viewport probably being much quicker to work with, and denoiser may not be as mushy. The other fact is that Daz, as far as I know, is sitll using older iRay drivers. Someone in Dev can correct me if I'm wrong. So, the drivers wouldn't be able to utilize CUDA to it's full efficiency.
What I do see a huge gain in, from what I gleaned from the speech, is that any AI workflows will be greatly improved. If you use a local AI in your process at all, there will probably be a huge bump in token generation with the images.
I know, AI can be a touchy subject, but I can also see how it can work *with* an artist to help with image creation.
Thoughts? Comments? Peanuts?

Iray drivers? What are they? Daz Studio is currently using an older version of Iray, yes - the chnage log shows they did try a newer version but then roilled back before a private build; I would be slightly surprised if even that had compatibility with the new cards, based on previous rollouts.
Wonder if it's because older cards 16-series, 20-series and maybe even 30-series may have issues with the newer version of IRay? And I could see Daz nixing that because only a handful of users would have had 40-series cards at the time...and even today how many people running Daz are running on 40 series, and how many who aren't are going to hop onto 50-series cards? For an enterprise-level 3D program, like Maya, etc, it's a no-brainer since corporations would be getting high-end hardware for their needs, but since Daz is a hobbist program, the developers need to stick with what works for the average user and not hop on the latest and greatest. Which is fine. It's a free program, and it's us users who help maintain it by purchasing from the store. Not saying, "BAH! THEY NEED TO UPGRADE IRAY!" Would be nice to have that option, but I can see why they won't. And I don't know how much of an issue it would be to toggle between versions, or have a separate installer...though, as a developer, that would be a nightmare to maintain.
It is what it is, really. I don't blame Daz for using the older version of IRay that works with most hardware out there. Maybe by the time the 60 or 70 series comes out, there will be enough of a 40+ marketshare out there to warrant it.
That's also why I don't really jump at excitement on Jansen Haung's speech about "how much faster the 50-series is over the 40-series!" For us Daz-heads, it all comes to VRAM capacity. 32GB of VRAM would be nice, but heck, I had a hard enough time fully utilizing 24GB on my 4090. I imagine render times are going to come in about on par with the previous gen. 4090 wasn't really much faster than a 3090, maybe by a couple of seconds and that was about it. And that's fine, I'm really not complaining. Just being a realist for people out there who have good 4090s who may be salivating over the new releases. Heck, if you've even got a 3090 and you're primarily using Daz, you won't see a significant gain.
If, though, you're in the market for a new card, probably best to hold off for the 50-series to come out (which should be a couple weeks).
I'm anxious to see what Gamers Nexus has to say about the card.
I've been needing a new pc and have been holding out till the 5090's were released simply because I need the Vram for alot of the scenes I like to make. I have a 4060 with 16 gigs and its not cutting it for my bigger scenes. I really don't keep up with the tech side of stuff so willl the 5090's actually work with Daz?
There's no reason it shouldn't work, unless nVidia drops support for IRay, which I really doubt they would. IRay is very common in particularly the automotive industry, and it's also the backbone of the RTX technology.

Like I mentioned, I think what we're going to see a difference in is the iray preview in the viewport, and possibly some uplift when denoising is used. Denoising uses the GPU's AI to approximate pixels next to the rendered pixels, so it only needs to render 1/2 of the pixels in order to extrapolate enough data to generate the other 1/2. According to Jensen, the new Blackwell will be able to generate the pixels quicker and with more accuracy. If you turn off denoising, you're forcing the GPU to calculate the raytracing for each pixel you're generating. My guess is with the 5090, and probably even the 5080, you'll get virtual "real time rendering" in the viewport, and you can probably even turn on denoising after 200 generations instead of after 500 generations.
I got the 3090 and the 4090 when they came out, I will be skipping this next one for sure, the 4090 works perfectly fine, and the 3090 on my other computer, when I render things simultaneously, I see maybe a few second difference. So I can't see the 5090 being that much of an upgrade.
I'm going to be getting one...my 4090 suffered a tragic accident. Luckily, I have insurance on my computer. Only thing is, insurance only paid me what I paid for it, not what it's worth today, and unlike most computer electronics, the value of the 4090 went up instead of down. Sigh. So, I have to pocket away a few more dollars to cover the cost, and I figured, "Well, if I gotta put away $500, why not $800 and get the next gen?"
I found my 4090 was 60% faster in Iray than my 3090 which equates to saving some 36 minutes on a render that would take 1 hour on the 3090. I'd certainly take that speed up again on a 5090 - but time will tell ..
This comment is complete nonsense--the 5090 has much faster memory (GDDR7 vs GDDR6) from a 3090 and a significantly higher number of CUDA cores. Based on the benchmark thread which shows the 4090 to be faster than the 3090, I would not be surprised (once Daz updates to make sure that it is compatible with the 5090) to see the 5090 is at least 50-60% faster in render time than a 3090.
Of course, the biggest issue will likely be availability once the cards launch, which will probably make it quite difficult to find one anywhere near the listed MSRP. Also, 575 watt power draw is a big jump from the 350 W my 3090 uses during rendering, so a new power supply is going to be a must (probably will need to look at something around 1500-1600 watts, given that newer CPUs also have a much higher power draw than older ones). I am currently in the process of rebuilding my PC (new motherboard, CPU and RAM should be here later this month), and so I am thinking about picking up a 5090 somewhere down the road and running it along with my 3090 for Daz renders--I would expect to see the combination of the two reduce my render times by 70% or so, which would greatly speed up my workflows.
There is every precedent for thinking Iray will not work on 50x0 cards initially - that has been the case for the 20x0, 30x0, and 40x0 cards too - not because of Daz dilatoriness but because nVidia has needed to release a new version of Iray, at least a couple of months after the cards came out. Of course Daz does then need to test the new version, so there will be at least a slight further delay before ity reaches Studio users, but Daz doesn't deliberately hold back on Iray updates unless there is cause.
For DAZ Studio renders only, a upgrade makes no sense unless you are rolling in dough.
I'm very much in need right now. My 4090 got some liquid damage, I'm not sure how...I think some dummy (me) put a leaky vape ontop of my computer and some juice dripped down right into the vent on my Geforce card.
Luckily my insurance did cover the cost of replacement, since I did put a rider on my computer in case of dumb things like that (I'm not going to gamble something dumb happening to my computer, and being out a $2500 video card+components)
