Performance comparison: which is faster?
GeForce RTX 5070 Ti (NVIDIA, 2025) and GeForce RTX 3090 Ti (NVIDIA, 2022) are compared here. Compare scores and VRAM, generative AI usability, and CPUs that pair well with each GPU.
Overall performance: RTX 5070 Ti is about 18.6% faster
For generative AI, the higher-VRAM RTX 3090 Ti（24GB） has the advantage. For gaming, prioritize performance score and CPU compatibility; for AI, prioritize VRAM.
Relative performance score (higher is faster). Actual fps varies by resolution, game, and CPU configuration.
| Item | RTX 5070 Ti | RTX 3090 Ti |
|---|---|---|
| Performance Score | 35,000 | 29,500 |
| VRAM | 16GB | 24GB |
| Manufacturer | NVIDIA | NVIDIA |
| Series | RTX 50 | RTX 30 |
| Release Year | 2025 | 2022 |
| Compatible CPU Example | Ryzen 9 9950X3D | Ryzen 7 7800X3D |
These generative AI models can run on only one GPU because of the VRAM difference (Stable Diffusion, Flux, LLMs, and others).
— None (all models that run on RTX 3090 Ti also run here)
| If You Want To... | Recommended |
|---|---|
| Prioritize high fps and smooth performance in demanding games | RTX 5070 Ti |
| Run larger generative AI and LLM models | RTX 3090 Ti |
| Prioritize value and adequate performance | RTX 3090 Ti (the lower model is often sufficient) |
RTX 5070 Ti is about 18.6% higher by score (RTX 5070 Ti: 35000 points / RTX 3090 Ti: 29500 points). Actual fps also varies by resolution, game, and CPU, so price is a reasonable deciding factor when the gap is only a few percent.
RTX 5070 Ti has 16GB of VRAM, while RTX 3090 Ti has 24GB; RTX 3090 Ti has more. If image generation or a local LLM is even a possibility, the higher-VRAM option provides more room.
Using our guideline, Ryzen 9 9950X3D pairs well with RTX 5070 Ti and Ryzen 7 7800X3D with RTX 3090 Ti (CPU:GPU ≈ 0.9:1). If the CPU is too weak, replacing the GPU may not raise fps, so check the combination before buying.
