Performance comparison: which is faster?
GeForce RTX 4070 (NVIDIA, 2023) 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: RTX 4070 is about 6.8% 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 4070 | RTX 4080 Laptop GPU |
|---|---|---|
| Performance Score | 23,500 | 22,000 |
| VRAM | 12GB | 12GB |
| Manufacturer | NVIDIA | NVIDIA |
| Series | RTX 40 | RTX 40 |
| Release Year | 2023 | 2023 |
| Compatible CPU Example | Core i9-10900K | Core i5-13420H |
| If You Want To... | Recommended |
|---|---|
| Prioritize high fps and smooth performance in demanding games | RTX 4070 |
| Run larger generative AI and LLM models | RTX 4070 |
| Prioritize value and adequate performance | RTX 4080 Laptop GPU (the lower model is often sufficient) |
RTX 4070 is about 6.8% higher by score (RTX 4070: 23500 points / RTX 4080 Laptop GPU: 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.
Both have 12GB of VRAM, so the range of generative AI models they can run is nearly the same.
Using our guideline, Core i9-10900K pairs well with RTX 4070 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.
