Performance comparison: which is faster?
GeForce GTX 950 (NVIDIA, 2015) and GeForce GTX 660 Ti (NVIDIA, 2012) are compared here. Compare scores and VRAM, generative AI usability, and CPUs that pair well with each GPU.
Overall performance: GTX 950 is about 5% faster
Both have 2GB 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 950 | GTX 660 Ti |
|---|---|---|
| Performance Score | 4,200 | 4,000 |
| VRAM | 2GB | 2GB |
| Manufacturer | NVIDIA | NVIDIA |
| Series | GTX 900 | GTX 600 |
| Release Year | 2015 | 2012 |
| Compatible CPU Example | AMD Phenom II X4 945 | AMD Phenom II X4 945 |
| If You Want To... | Recommended |
|---|---|
| Prioritize high fps and smooth performance in demanding games | GTX 950 |
| Run larger generative AI and LLM models | GTX 950 |
| Prioritize value and adequate performance | GTX 660 Ti (the lower model is often sufficient) |
GTX 950 is about 5% higher by score (GTX 950: 4200 points / GTX 660 Ti: 4000 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 2GB of VRAM, so the range of generative AI models they can run is nearly the same.
Using our guideline, AMD Phenom II X4 945 pairs well with GTX 950 and AMD Phenom II X4 945 with GTX 660 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.
