Performance comparison: which is faster?
GeForce GTX 780 Ti (NVIDIA, 2014) and GeForce GTX 970 (NVIDIA, 2015) 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 GTX 970（4GB） 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 | GTX 780 Ti | GTX 970 |
|---|---|---|
| Performance Score | 7,000 | 7,000 |
| VRAM | 3GB | 4GB |
| Manufacturer | NVIDIA | NVIDIA |
| Series | GTX 700 | GTX 900 |
| Release Year | 2014 | 2015 |
| Compatible CPU Example | Ryzen 3 1200 | Ryzen 3 1200 |
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 970 also run here)
| If You Want To... | Recommended |
|---|---|
| Prioritize high fps and smooth performance in demanding games | GTX 780 Ti |
| Run larger generative AI and LLM models | GTX 970 |
| Prioritize value and adequate performance | GTX 780 Ti (the lower model is often sufficient) |
Their scores are nearly identical (GTX 780 Ti: 7000 points / GTX 970: 7000 points). In this case, compare price, VRAM, and power draw.
GTX 780 Ti has 3GB of VRAM, while GTX 970 has 4GB; GTX 970 has more. If image generation or a local LLM is even a possibility, the higher-VRAM option provides more room.
Using our guideline, Ryzen 3 1200 pairs well with GTX 780 Ti and Ryzen 3 1200 with GTX 970 (CPU:GPU ≈ 0.9:1). If the CPU is too weak, replacing the GPU may not raise fps, so check the combination before buying.
