Daz Render speed question

[datazzguy]

A new rig that I'm tempted to get comes with a 16GB 4070ti Super, and my current one only has a standard 12GB 3060. On various benchmark sites it says the former is anywhere from 35% to 180% faster during various types of rendering.

The new machine also comes with a 7800X3D, replacing my old 5600G. I don't use the CPU for rendering, so I'm not sure how much that will affect the rendering speed.

With only a 4GB VRAM difference, how much faster will a standard Daz render actually be? Will it render twice as fast or just slightly faster?

The VRAM won't have any impact on rendering times. It just lets you render out a much larger scene load.

What does effect the speed is the CUDA cores and the 4070Ti has more than twice as many as the 3060, so that's why a lot of benchmarks say ~90-100 % speed increase.

I have the 4060Ti (16GB) and it only has 768 more CUDA cores so it's faster than a 3060 but not near as fast as a 4070Ti.

If the price is good, snap it up. 4000-series cards are few and far between right now (at least for anything with more than 12GB) and the 5000 series doesn't work with DAZ yet.

EDIT: forgot to mention, that the nicer CPU will make DAZ run smoother in the viewport. Also lets you mutlitask more. I'm still on an old 10th gen i3 CPU and I can still run 4 or 5 other aps while DAZ is cooking a render... unless it's a VRAM heavy one.

Not just this. The CPU is also used during DForce simulation, when loading overlay/L.I.E, and during the internal preparation step prior to the rendering itself.
While the last part tend to be a small part of the whole rendering process, it's still a significant one. It would be ridiculous to have a GPU so powerful that you can render a basic scene in one minute, but a so old/slow CPU that Daz Studio need one other minute to (basically speaking) prepare the data, send them to the GPU, then get the result.

The same apply to the hard drive where the assets are stored. The faster it is, the faster textures will be loaded into the memory. Here too it will not significantly speed-up the whole process, since the gain would be around 2 or 3 minutes at max, but even if each render need 30 minutes to render, it's still one render less every 10 or 15 renders.

Both are side optimization, but if the goal is to batch render for a game, it can represent 5 more renders by sessions.

Ya, I forgot about Dforce simulations and scene loading times. DAZ however is fairly light-weight on CPU usage except during those specific times. And one thing that has changed recently is that version 4.23 loads scenes a lot faster. I noticed it right away when I upgraded from 4.21.

And, of course, all this really depends on what you want to do with DAZ. If you're just doing renders for yourself and production is not a thing, a mid-level PC/CPU/RAM combo is fine. But if you plan on doing a game and there's lots of animations, shaving even 30 seconds off a render can mean the difference between a 4 hour batch run and an 8 hour run, when you're doing a 500 frame image series, for example.


Here's my simple rip off of the Maslow’s Hierarchy of Needs pyramid -in regards to DAZ
(most important needs on bottom) ...

_____________
__________/..... \
_________/ CPU* \ * Anything later than a 10th gen 4-core CPU (or a Ryzen 3 - 3300 or better)
________/________\
_______/ SSD (M.2 ) \ <--- speed of loading assets into RAM --> VRAM
______/____________\
_____/... CUDA Cores...\ <--- Speed of the rendering
____/________________\
___/... RAM (32GB min)....\ <-- should be at least 2 x time the VRAM, but starting to look like 4 x VRAM is better
__/____________________\
_/..VRAM (max u can afford)..\ <-- How much textures/objects/characters you can render in a single pass
/________________________\

EDIT: I hate BBcode ... lol

You should take a look on my thread about normals. It will help to reduce the taxation of the system and thus speed up the render times.

Also, consider using a iray cam for quicker scene rendering. Need to learn to use lights for that to work, otherwise it looks not great.
Anyhow, these are my tips. It helped me.
