Is 3060ti a bottleneck?

in Technical Help (nuts n bolts)

Hi guys, Sorry if I am posting it in wrong category. But I wanted to know if someone out there using a 3060ti for rendering and getting memory overload issues. Recently I am getting these issues a lot.  Even rendering 2 genesis 8 model together with sub-d level 3 or 2 is creating this issue. Now I am trying to render to g9 characters and using cpu fall back to make those renders. Still looking is there any hope or tweaks I can do to make renders on my good old 3060ti or should i look for getting a new gpu which one? I have  i5 12gen 10 cores if that helps to suggest me a gpu. Quality is a concern to me. Thank you for your help.

    Have you tried reducing texture sizes (manually or using Scene Optimiser)? There is no benefit in having textures that have a greater pixel count than the textured area of the model will have in the final render, and textures do tend to eat a lot of memory. Also check that you don't have SubD set too high - again, if the extra detail is too small to see in the final render then it is just wasting memory (and each SubD level quadruples the polygon count).

    The GPU VRAM does not affect the final image quality - you'll get the same image via CPU as you get from the fastest GPU. It simply affects how long it takes to get to that point.

    The 3060Ti has 8Gb VRAM, so is more likely to fill up than many others. Windows reserves around 2Gb VRAM, then each base res character takes around 2Gb (ish), and a background can take a similar amount. So.. an 8Gb GPU will cope with (Windows reserved bit) + 2 characters and a background, and not a huge amount more.

    So... changing what you have is a decision you have to make. A 12Gb RTX3060 without Ti will work on bigger scenes (say 4 base res characters + background or maybe 2 off Sub-D'3' characters), but more slowly than the 3060Ti when the Ti is in capacity - but much faster than the Ti when it drops out. It's down to the VRAM, more=more useful. Similar limitations act on other RTX cards. I have an i5-13600K processor, and it uses 25% cpu feeding my 12Gb RTX3060. As you have an i5-12xxx cpu, it should be able to keep an RTX4060 fed with data, but I suspect a much faster GPU (say RTX4090) and the CPU data transfer to the GPU would act as a throttle to performance. (I had a 2014 Xeon in my last machine, and it slightly throttled my 6Gb GTX1060 GPU because it couldn't keep up with the data rate). You pays your money & takes your choice.

    My advice would be to consider a 16Gb RTX 4060 TI  first, and if too expensive, look at an RTX 3060 12Gb. But, it's not my money I'm suggesting is spent. When it was my money, I went for the 12Gb RTX3060.

    Regards,

    Richard
