Performance comparison: which is faster?
GeForce RTX 4080 Laptop GPU (NVIDIA, 2023) and GeForce RTX 4070 Laptop GPU (NVIDIA, 2023) are compared here. Compare scores and VRAM, generative AI usability, and CPUs that pair well with each GPU.
Overall performance: RTX 4080 Laptop GPU is about 10% faster
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 4080 Laptop GPU | RTX 4070 Laptop GPU |
|---|---|---|
| Performance Score | 22,000 | 20,000 |
| VRAM | 12GB | 8GB |
| Manufacturer | NVIDIA | NVIDIA |
| Series | RTX 40 | RTX 40 |
| Release Year | 2023 | 2023 |
| Compatible CPU Example | Core i5-13420H | Core Ultra 5 238V |
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 4080 Laptop GPU |
| Run larger generative AI and LLM models | RTX 4080 Laptop GPU |
| Prioritize value and adequate performance | RTX 4070 Laptop GPU (the lower model is often sufficient) |
RTX 4080 Laptop GPU is about 10% higher by score (RTX 4080 Laptop GPU: 22000 points / RTX 4070 Laptop GPU: 20000 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 4080 Laptop GPU has 12GB of VRAM, while RTX 4070 Laptop GPU has 8GB; 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 i5-13420H pairs well with RTX 4080 Laptop GPU and Core Ultra 5 238V with RTX 4070 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.
