Performance comparison: which is faster?
GeForce GTX 1660 (NVIDIA, 2019) and GeForce GTX 1060 6GB (NVIDIA, 2016) are compared here. Compare scores and VRAM, generative AI usability, and CPUs that pair well with each GPU.
Overall performance: GTX 1660 is about 16.5% faster
Both have 6GB of VRAM, so they support a similar range of generative AI models. 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 1660 | GTX 1060 6GB |
|---|---|---|
| Performance Score | 9,900 | 8,500 |
| VRAM | 6GB | 6GB |
| Manufacturer | NVIDIA | NVIDIA |
| Series | GTX 16 | GTX 10 |
| Release Year | 2019 | 2016 |
| Compatible CPU Example | Core i7-3770K | Core i3-9100 |
| If You Want To... | Recommended |
|---|---|
| Prioritize high fps and smooth performance in demanding games | GTX 1660 |
| Run larger generative AI and LLM models | GTX 1660 |
| Prioritize value and adequate performance | GTX 1060 6GB (the lower model is often sufficient) |
GTX 1660 is about 16.5% higher by score (GTX 1660: 9900 points / GTX 1060 6GB: 8500 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.
Both have 6GB of VRAM, so the range of generative AI models they can run is nearly the same.
Using our guideline, Core i7-3770K pairs well with GTX 1660 and Core i3-9100 with GTX 1060 6GB (CPU:GPU ≈ 0.9:1). If the CPU is too weak, replacing the GPU may not raise fps, so check the combination before buying.
