Performance comparison: which is faster?
GeForce RTX 4070 SUPER (NVIDIA, 2024) and GeForce RTX 4090 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 4090 Laptop GPU（16GB） 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 4070 SUPER | RTX 4090 Laptop GPU |
|---|---|---|
| Performance Score | 27,000 | 27,000 |
| VRAM | 12GB | 16GB |
| Manufacturer | NVIDIA | NVIDIA |
| Series | RTX 40 | RTX 40 |
| Release Year | 2024 | 2023 |
| Compatible CPU Example | Ryzen 9 7900X | Core i7-14700HX |
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 4090 Laptop GPU also run here)
| If You Want To... | Recommended |
|---|---|
| Prioritize high fps and smooth performance in demanding games | RTX 4070 SUPER |
| Run larger generative AI and LLM models | RTX 4090 Laptop GPU |
| Prioritize value and adequate performance | RTX 4070 SUPER (the lower model is often sufficient) |
Their scores are nearly identical (RTX 4070 SUPER: 27000 points / RTX 4090 Laptop GPU: 27000 points). In this case, compare price, VRAM, and power draw.
RTX 4070 SUPER has 12GB of VRAM, while RTX 4090 Laptop GPU has 16GB; RTX 4090 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, Ryzen 9 7900X pairs well with RTX 4070 SUPER and Core i7-14700HX with RTX 4090 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.
