Vantage, Corona and New GPU

[amit_gedia]

Hi All and the developers,
I am planning to upgrade my GPU from GTX 1070 to RTX TUF 4070 Ti Super OC. Will this new GPU be useful for Vantage, Corona and VRay GPU rendering. any thoughts on this really help me buy or upgrade to this new GPU.
Thank you in advance.

What's the vram on it? That's important for large size projects. I'm already hitting a vram ceiling with my rtx 4090 with 16gb. Also Corona is a cpu centric renderer. Does not depend on gpu power. Vray and Vantage do.

A 4090 does have 24gb.
But yes vram is the most important factor.

Keep in mind that there should be a new generation of Nvidia GPUs in a few months. RTX 40 and 30 generations were each around 2x faster than their predecessors.

The 4070 Ti Super OC has 16GB VRAM. Also the new generations of Nvidia GPU's that will be released in few months will be much more costlier than the present ones which ultimately will be out of my budget too. So just wanted to know if this 4070 Ti Super OC GPU will be enough to do every day archviz tasks and not too heavy tasks. Will vantage render in a speedy way at 2K or max 4K resolution.

If you have a tight budget any 4070 will do.

Ok, Thank you for your reply and the update.

Hi all, I want to chime in here since I'm also in the process of looking for a new GPU. I’m looking to buy a new PC for work and rendering. While it’s going to be a Threadripper build, I also would want to upgrade my GPU for Vantage, Unreal and AI. The RTX4090 has the most VRAM, but it’s also very expensive. Would an RTX 4080 Super be enough? Or has anybody any experience with the AMD rx 7900 xtx, which also has 24GB VRAM and costs less than half of the 4090? Is NVIDIA required/better than AMD for Unreal and Vantage?

What is "enough" depends on what you're rendering and it's very hard to estimate without actually loading your scenes to see how much VRAM they use. It's easier to estimate what the render resolution requires. For example when I open an empty scene the render dialog tells me that rendering a 4K image would require over 2GB more memory than 720p and an 8K render requires over 9GB of additional VRAM for pixel buffers. So if you get a 16GB card you would have ~12GB for textures and geometry at 4K. If your workflow is through 3ds Max live link some of the memory will be used by Max, etc.

AMD support is still a bit experimental. We have very few users on AMD and we're not getting feedback (which may also mean it works for them). There are a couple of limitations on AMD and Intel GPUs. Video encoding is not implemented (this is just an inconvenience - you can easily encode a rendered image sequence with free software). The bigger limitation is that DLSS and Optix denoisers are not available - the problem is mostly with the latter, because Optix is the only option for temporally stable final render denoising. So if you're rendering an animation you would have to use a lot more samples and it may still flicker. We hope that the Intel Open Image denoiser will at some point also support temporally stable denoising to resolve this.

Hi, sorry about the late reply. Your answer was very helpful, there are not many (if any) AMD GPUS in Vantage benchmarks and I was also not aware of the limitations. NVIDIA may be more expensive, but since it will be faster and more flexible, I think it's a better investment.
Thanks a lot.
