4070 Ti Super 16GB vs RTX 5070 12GB for casual gaming + local AI/ML workloads?

Posted by Right_Tangelo_2760@reddit | buildapc | View on Reddit | 14 comments

Trying to decide between:

RTX 4070 Ti Super 16GB

RTX 5070 12GB

My use case is:

- casual gaming

- local AI/ML workloads

- Ollama / local LLMs

- Stable Diffusion / ComfyUI

- some CUDA experimentation

- maybe light LoRA fine-tuning later

I’m not doing hardcore enterprise-scale training, but I do want something that won’t feel limiting in 1 to 2 years.

From benchmarks, the 5070 seems to have newer AI features + GDDR7, but the 4070 Ti Super has 16GB VRAM and stronger raw performance.

For people who actually use these cards:

how limiting is 12GB in practice?

do you hit VRAM walls often?

any regrets choosing one over the other?

how’s thermals/power/noise?

Would really appreciate real-world experiences rather than benchmarks.

For AI more ram is what you want. Gaming too, really.

I have a 9070xt and yeah, it’ll be a better choice for gaming but OP implies gaming is secondary here. He’s better off with Nvidia. ROCm has improved but while tools like LM studio, ComfyUI and Ollama work for me, KohyaSS has been a PITA.

Room is still isn't mature so i need nvidia

A lot of the time it's fine, only very specific applications where CUDA is ahead now. Check benchmarks for your specific application, the more recent the better.

The 4070ti Super no question if you’re legitimately planning AI workloads. The extra 4GB will be a major improvement as not only will performance be better, you can also use larger models.

Gaming performance will be close. Obviously the 5070 will have newer features but since you mention casual gaming, I would think that doesn’t matter.

Had both . Kept my 4070 ti super

4070ti Super is superior in all cases. It has more VRAM, it is more powerful and just a better card.
I doubt you will make any sense with AI/LLMs with 12 Gb VRAM.

Would you still pick the 4070 Ti Super if both were basically the same price? The price difference for me is minimal, which is why I’m leaning toward the Ti Super.

Trying to understand whether this is mainly a VRAM issue, or if the 5070 also falls behind in real AI workloads once you start using:

Ollama
ComfyUI
SDXL/Flux
LoRA training
13B+ models

Most gaming benchmarks make them look close, but AI users seem much more biased toward the 4070 Ti Super.

are both new? i guess the 4070 doesn't exist new anymore? 4070 TiS is the superior card here

Right_Tangelo_2760@reddit (OP)

Yes I'm getting one, new but due to scarcity they are inflating the price.

4070ti Super, once again, is superior GPU for any case. I don't know what do you expect from me. I already said - it is more powerful, it has more VRAM.

You can easily can relative performance on Techpowerup.

Thanks it helped me a lot

I am in this exact situation, but my workload is more towards simulation work and some learning. I found a 4070ts for maybe $50 more locally, and I think I am leaning more towards that due to more CUDA cores and vram
