Performance comparison: which is faster?
GeForce GTX 780 (NVIDIA, 2014) and GeForce GTX 680 (NVIDIA, 2012) are compared here. Compare scores and VRAM, generative AI usability, and CPUs that pair well with each GPU.
Overall performance: GTX 780 is about 21.2% faster
For generative AI, the higher-VRAM GTX 780（3GB） 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 | GTX 680 |
|---|---|---|
| Performance Score | 6,300 | 5,200 |
| VRAM | 3GB | 2GB |
| Manufacturer | NVIDIA | NVIDIA |
| Series | GTX 700 | GTX 600 |
| Release Year | 2014 | 2012 |
| Compatible CPU Example | AMD A10-7890K | Core i3-4170 |
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 780 also run here)
| If You Want To... | Recommended |
|---|---|
| Prioritize high fps and smooth performance in demanding games | GTX 780 |
| Run larger generative AI and LLM models | GTX 780 |
| Prioritize value and adequate performance | GTX 680 (the lower model is often sufficient) |
GTX 780 is about 21.2% higher by score (GTX 780: 6300 points / GTX 680: 5200 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.
GTX 780 has 3GB of VRAM, while GTX 680 has 2GB; GTX 780 has more. If image generation or a local LLM is even a possibility, the higher-VRAM option provides more room.
Using our guideline, AMD A10-7890K pairs well with GTX 780 and Core i3-4170 with GTX 680 (CPU:GPU ≈ 0.9:1). If the CPU is too weak, replacing the GPU may not raise fps, so check the combination before buying.
