Performance comparison: which is faster?
GeForce RTX 2070 (NVIDIA, 2018) and GeForce RTX 4050 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 2070 is about 8% faster
For generative AI, the higher-VRAM RTX 2070（8GB） 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 2070 | RTX 4050 Laptop GPU |
|---|---|---|
| Performance Score | 13,500 | 12,500 |
| VRAM | 8GB | 6GB |
| Manufacturer | NVIDIA | NVIDIA |
| Series | RTX 20 | RTX 40 |
| Release Year | 2018 | 2023 |
| Compatible CPU Example | Ryzen 5 1600 | Core Ultra 5 135U |
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 2070 also run here)
| If You Want To... | Recommended |
|---|---|
| Prioritize high fps and smooth performance in demanding games | RTX 2070 |
| Run larger generative AI and LLM models | RTX 2070 |
| Prioritize value and adequate performance | RTX 4050 Laptop GPU (the lower model is often sufficient) |
RTX 2070 is about 8% higher by score (RTX 2070: 13500 points / RTX 4050 Laptop GPU: 12500 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 2070 has 8GB of VRAM, while RTX 4050 Laptop GPU has 6GB; RTX 2070 has more. If image generation or a local LLM is even a possibility, the higher-VRAM option provides more room.
Using our guideline, Ryzen 5 1600 pairs well with RTX 2070 and Core Ultra 5 135U with RTX 4050 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.
