Performance comparison: which is faster?
GeForce RTX 3070 Ti (NVIDIA, 2021) and GeForce RTX 4080 Laptop GPU (NVIDIA, 2023) are compared here. Compare scores and VRAM, generative AI usability, and CPUs that pair well with each GPU.
Overall performance: nearly equal
For generative AI, the higher-VRAM RTX 4080 Laptop GPU（12GB） 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 3070 Ti | RTX 4080 Laptop GPU |
|---|---|---|
| Performance Score | 22,000 | 22,000 |
| VRAM | 8GB | 12GB |
| Manufacturer | NVIDIA | NVIDIA |
| Series | RTX 30 | RTX 40 |
| Release Year | 2021 | 2023 |
| Compatible CPU Example | Core i5-11600 | Core i5-13420H |
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 4080 Laptop GPU also run here)
| If You Want To... | Recommended |
|---|---|
| Prioritize high fps and smooth performance in demanding games | RTX 3070 Ti |
| Run larger generative AI and LLM models | RTX 4080 Laptop GPU |
| Prioritize value and adequate performance | RTX 3070 Ti (the lower model is often sufficient) |
Their scores are nearly identical (RTX 3070 Ti: 22000 points / RTX 4080 Laptop GPU: 22000 points). In this case, compare price, VRAM, and power draw.
RTX 3070 Ti has 8GB of VRAM, while RTX 4080 Laptop GPU has 12GB; RTX 4080 Laptop GPU has more. If image generation or a local LLM is even a possibility, the higher-VRAM option provides more room.
Using our guideline, Core i5-11600 pairs well with RTX 3070 Ti and Core i5-13420H with RTX 4080 Laptop GPU (CPU:GPU ≈ 0.9:1). If the CPU is too weak, replacing the GPU may not raise fps, so check the combination before buying.
