Two rtx 3060 GPU

Good morning everybody.

 

This is adressed to someone with some knowledge on 3D PC Hardware.

 

I am going to add one more GPU RTX 3060 to my config (see below)

 

Would you advice to choose TI model?

 

Thanks in advance

 

AMD Ryzen 7 3800X, 8x 3,9GHz

Gigabyte A520 AORUS Elite, S. AM4 v2

NVIDIA GeForce RTX 3060 12Go

32 Go DDR4-3200 |

1000w gold alim

    How much of the 12GB on your current card do you tend to use when rendering? The Ti has only 8, so if you frequently approach that (it isn't all available to DS) you would be better off with the non-Ti version - on the other hand, the extra speed might be useful if you typically don't push past what an 8GB card can handle.

    currently 95 or 100% use on certain scenes. it's not a question of replacing but adding, I was thinking  12Gb+8Gb.. No?

    Adding another card won't give you more memory to use.

    That's a very important information . Why is it so?

    So, to summarize, adding a new GPU will improve the calculation, then speed up the render, but not the Vram capacity.

    laughThanks all for your help on this matter!

    That's right, each card works separately and passes the results of its calculations back to the main process, which merges them together.

    And... I you buy the 3060TI with 8GB VRAM, it will only participate in rendering as long as the scene fits the 8GB VRAM, if the scene doesn't fit, only the 12GB version will be used unless the scene exceeds that cards VRAM as well.

    We can always hope that NVidia adds some sort of memory management to IRay to get around the VRAM limitations.

    There is the NVLink if one has two (or more) identical 3090, 2080 or 2070 Super GPU's
