Performance comparison: which is faster?
GeForce GTX 560 Ti (NVIDIA, 2011) and GeForce GTX 660 (NVIDIA, 2012) 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 660（2GB） 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 560 Ti | GTX 660 |
|---|---|---|
| Performance Score | 3,500 | 3,500 |
| VRAM | 1GB | 2GB |
| Manufacturer | NVIDIA | NVIDIA |
| Series | GTX 500 | GTX 600 |
| Release Year | 2011 | 2012 |
| Compatible CPU Example | AMD A6-7470K | AMD A6-7470K |
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 660 also run here)
| If You Want To... | Recommended |
|---|---|
| Prioritize high fps and smooth performance in demanding games | GTX 560 Ti |
| Run larger generative AI and LLM models | GTX 660 |
| Prioritize value and adequate performance | GTX 560 Ti (the lower model is often sufficient) |
Their scores are nearly identical (GTX 560 Ti: 3500 points / GTX 660: 3500 points). In this case, compare price, VRAM, and power draw.
GTX 560 Ti has 1GB of VRAM, while GTX 660 has 2GB; GTX 660 has more. If image generation or a local LLM is even a possibility, the higher-VRAM option provides more room.
Using our guideline, AMD A6-7470K pairs well with GTX 560 Ti and AMD A6-7470K with GTX 660 (CPU:GPU ≈ 0.9:1). If the CPU is too weak, replacing the GPU may not raise fps, so check the combination before buying.
