Performance comparison: which is faster?
GeForce RTX 4050 Laptop GPU (NVIDIA, 2023) and GeForce GTX 1070 Ti (NVIDIA, 2017) are compared here. Compare scores and VRAM, generative AI usability, and CPUs that pair well with each GPU.
Overall performance: RTX 4050 Laptop GPU is about 8.7% faster
For generative AI, the higher-VRAM GTX 1070 Ti（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 4050 Laptop GPU | GTX 1070 Ti |
|---|---|---|
| Performance Score | 12,500 | 11,500 |
| VRAM | 6GB | 8GB |
| Manufacturer | NVIDIA | NVIDIA |
| Series | RTX 40 | GTX 10 |
| Release Year | 2023 | 2017 |
| Compatible CPU Example | Core Ultra 5 135U | Core i7-6700 |
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 GTX 1070 Ti also run here)
| If You Want To... | Recommended |
|---|---|
| Prioritize high fps and smooth performance in demanding games | RTX 4050 Laptop GPU |
| Run larger generative AI and LLM models | GTX 1070 Ti |
| Prioritize value and adequate performance | GTX 1070 Ti (the lower model is often sufficient) |
RTX 4050 Laptop GPU is about 8.7% higher by score (RTX 4050 Laptop GPU: 12500 points / GTX 1070 Ti: 11500 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 4050 Laptop GPU has 6GB of VRAM, while GTX 1070 Ti has 8GB; GTX 1070 Ti has more. If image generation or a local LLM is even a possibility, the higher-VRAM option provides more room.
Using our guideline, Core Ultra 5 135U pairs well with RTX 4050 Laptop GPU and Core i7-6700 with GTX 1070 Ti (CPU:GPU ≈ 0.9:1). If the CPU is too weak, replacing the GPU may not raise fps, so check the combination before buying.
