Performance comparison: which is faster?
GeForce RTX 3080 (NVIDIA, 2020) and GeForce RTX 3070 Ti (NVIDIA, 2021) are compared here. Compare scores and VRAM, generative AI usability, and CPUs that pair well with each GPU.
Overall performance: RTX 3080 is about 11.4% faster
For generative AI, the higher-VRAM RTX 3080（10GB） 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 3080 | RTX 3070 Ti |
|---|---|---|
| Performance Score | 24,500 | 22,000 |
| VRAM | 10GB | 8GB |
| Manufacturer | NVIDIA | NVIDIA |
| Series | RTX 30 | RTX 30 |
| Release Year | 2020 | 2021 |
| Compatible CPU Example | Ryzen 5 8600G | Core i5-11600 |
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 3080 also run here)
| If You Want To... | Recommended |
|---|---|
| Prioritize high fps and smooth performance in demanding games | RTX 3080 |
| Run larger generative AI and LLM models | RTX 3080 |
| Prioritize value and adequate performance | RTX 3070 Ti (the lower model is often sufficient) |
RTX 3080 is about 11.4% higher by score (RTX 3080: 24500 points / RTX 3070 Ti: 22000 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 3080 has 10GB of VRAM, while RTX 3070 Ti has 8GB; RTX 3080 has more. If image generation or a local LLM is even a possibility, the higher-VRAM option provides more room.
Using our guideline, Ryzen 5 8600G pairs well with RTX 3080 and Core i5-11600 with RTX 3070 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.
