Performance comparison: which is faster?
GeForce GTX 1660 (NVIDIA, 2019) and GeForce GTX 980 (NVIDIA, 2015) are compared here. Compare scores and VRAM, generative AI usability, and CPUs that pair well with each GPU.
Overall performance: GTX 1660 is about 19.3% faster
For generative AI, the higher-VRAM GTX 1660（6GB） 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 1660 | GTX 980 |
|---|---|---|
| Performance Score | 9,900 | 8,300 |
| VRAM | 6GB | 4GB |
| Manufacturer | NVIDIA | NVIDIA |
| Series | GTX 16 | GTX 900 |
| Release Year | 2019 | 2015 |
| Compatible CPU Example | Core i7-3770K | Ryzen 3 1300X |
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 1660 also run here)
| 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 980 (the lower model is often sufficient) |
GTX 1660 is about 19.3% higher by score (GTX 1660: 9900 points / GTX 980: 8300 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 1660 has 6GB of VRAM, while GTX 980 has 4GB; GTX 1660 has more. If image generation or a local LLM is even a possibility, the higher-VRAM option provides more room.
Using our guideline, Core i7-3770K pairs well with GTX 1660 and Ryzen 3 1300X with GTX 980 (CPU:GPU ≈ 0.9:1). If the CPU is too weak, replacing the GPU may not raise fps, so check the combination before buying.
