Better CPU for daz3d

johnmaxx09

i'm gonna build a pc for daz ... rtx 3060 12gb with 32gb ram but i'm confusing about cpu : these are i3 12100 with 4 cores and 8 threads has more single core perfomence or ryzen 3600 with 6 cores and 12 threads has for multi core perfomence ... anyone tell which will be better for daz3d ?

Richard Haseltine

Assuming your GPU can handle rendering (and that you are using Iray not 3Delight) and simulation then you would probably gain more from high single-copre performance in DS, currently at least.

Jay Versluis

I second what Richard said, higher single core performance tops higher multi core performance in Daz Studio at the time of writing.

IMO neither of the CPUs you've mentioned are partiucularly good for anything other than email and light web browsing. I strongly suggest you look into at least an Intel i5 or i7, even an older 10th or 11th generation will top an i3, which are made for low power consumption.

i3 12100 (12th gen) has more single core perfomence than previous gen i5 or i7 (10th or 11th)

I wouldn't discount an AMD solution either.  While Daz itself, in its current 4.X version favors single core... who know what is in store for Daz 5.

Regardless of CPU.  You are probably less than 3 weeks away from the 4060 Ti 16GB card being launched.  It is supposed to be $499... but if it is like the other 4060 Ti etc that have launched, they are already selling at a discount.  That would give you 3070 performance (depending on scenario) with 16GB of VRam goodness.

Running Daz Studio itself is not super CPU demanding. But it depends on how you use Daz. The CPU comes into play for a variety of things, like anything using "smoothing". Any items that use smoothing are going to recalculate when you move anything at all, whether posing, moving the camera, or adding stuff. The more items with smoothing, and the more smoothing iterations they have, will cause Daz Studio to lag when you do these things on a weaker CPU.

But how much that is a factor depends on you. You can also mitigate it by disabling smoothing until you are ready to render.

Other things that can drag DS down are high poly meshes or lots of 8k textures. Again, it depends on how heavy your typical scene is. You can also mitigate this since there are separate subdivision settings for the render and viewport. Some items let you hide resource heavy stuff until rendering, or you can do it manually by hiding it in the scene tab.

When I moved from a 8 year old i5 to a 5800x the difference was massive and liberating. Even the 12100 would be a huge upgrade over that old i5 4690k I had, it has the same number of cores but doubles the threads to 8 and has way more IPC. However that i5 was an old CPU that predates the "core wars" that AMD kicked off with Ryzen. CPU tech has moved very fast in recent years since Ryzen launched and even low end parts are pretty decent now. You get roughly around 10% IPC gain each year, give or take, and so you can sort of guesstimate how much faster a CPU is over your old one core-for-core. You can absolutely do more than check email with a 12100, though you can't expect the world. I'd still consider trying to get a slightly more mid range part (like i5) but I don't know how much you need it. Your GPU is the most important thing for Daz, so it always best to put your money into GPU over CPU if budget is an issue. If I had a choice between picking a faster GPU or CPU and skimping on the other, I'd take the GPU every single time. However you don't want to skimp so much that the CPU struggles to run DS itself.

Consider what you have now, and how well DS runs for you right now with what you have (not talking about rendering). If your CPU is really old, like my i5 was, then anything will be an upgrade.

I know that doesn't directly answer your question, but the true answer really depends on how you use DS (and other apps for that matter). How much do you push your scenes, and how much do you plan on pushing your scenes in the future. A bigger scene is not only going to take longer to render, thus needing a good GPU, but might be harder to navigate in DS while building it, thus needing a good CPU. There are things that DS is just slow at doing, and no amount of hardware can help. Like loading times with a large library or scene. That has been a big issue for years, though a recent version of DS helped cut loading times a lot. Still, the software is the main limitation in this aspect, not the hardware (obviously having the content library on a single drive, and that drive being SSD does help.)
