Performance comparison: which is faster?
GeForce RTX 3080 12GB (NVIDIA, 2022) and GeForce RTX 4070 (NVIDIA, 2023) are compared here. Compare scores and VRAM, generative AI usability, and CPUs that pair well with each GPU.
Overall performance: RTX 3080 12GB is about 6.4% faster
Both have 12GB of VRAM, so they support a similar range of generative AI models. 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 12GB | RTX 4070 |
|---|---|---|
| Performance Score | 25,000 | 23,500 |
| VRAM | 12GB | 12GB |
| Manufacturer | NVIDIA | NVIDIA |
| Series | RTX 30 | RTX 40 |
| Release Year | 2022 | 2023 |
| Compatible CPU Example | Ryzen 5 8600G | Core i9-10900K |
| If You Want To... | Recommended |
|---|---|
| Prioritize high fps and smooth performance in demanding games | RTX 3080 12GB |
| Run larger generative AI and LLM models | RTX 3080 12GB |
| Prioritize value and adequate performance | RTX 4070 (the lower model is often sufficient) |
RTX 3080 12GB is about 6.4% higher by score (RTX 3080 12GB: 25000 points / RTX 4070: 23500 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.
Both have 12GB of VRAM, so the range of generative AI models they can run is nearly the same.
Using our guideline, Ryzen 5 8600G pairs well with RTX 3080 12GB and Core i9-10900K with RTX 4070 (CPU:GPU ≈ 0.9:1). If the CPU is too weak, replacing the GPU may not raise fps, so check the combination before buying.
