Performance comparison: which is faster?
GeForce GTX 660 Ti (NVIDIA, 2012) and GeForce GTX 560 Ti (NVIDIA, 2011) are compared here. Compare scores and VRAM, generative AI usability, and CPUs that pair well with each GPU.
Overall performance: GTX 660 Ti is about 14.3% faster
For generative AI, the higher-VRAM GTX 660 Ti（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 660 Ti | GTX 560 Ti |
|---|---|---|
| Performance Score | 4,000 | 3,500 |
| VRAM | 2GB | 1GB |
| Manufacturer | NVIDIA | NVIDIA |
| Series | GTX 600 | GTX 500 |
| Release Year | 2012 | 2011 |
| Compatible CPU Example | AMD Phenom II X4 945 | 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 Ti also run here)
| If You Want To... | Recommended |
|---|---|
| Prioritize high fps and smooth performance in demanding games | GTX 660 Ti |
| Run larger generative AI and LLM models | GTX 660 Ti |
| Prioritize value and adequate performance | GTX 560 Ti (the lower model is often sufficient) |
GTX 660 Ti is about 14.3% higher by score (GTX 660 Ti: 4000 points / GTX 560 Ti: 3500 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 660 Ti has 2GB of VRAM, while GTX 560 Ti has 1GB; GTX 660 Ti has more. If image generation or a local LLM is even a possibility, the higher-VRAM option provides more room.
Using our guideline, AMD Phenom II X4 945 pairs well with GTX 660 Ti and AMD A6-7470K with GTX 560 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.
