CPU bottleneck check, compatible CPUs, and AI models it can run
GeForce GTX 980 / NVIDIA made / GTX 900 / Released 2015 Also known as: GTX980 / 980
GeForce GTX 980 (NVIDIA, released in 2015, also listed as GTX980 / 980) is a graphics card with a performance score of 8,300 and 4GB of VRAM, TDP 165W. If CPU compatibility and performance balance are poor, a CPU bottleneck occurs, preventing GTX 980 from reaching its full potential. In our estimate, the CPUs that pair best with GTX 980 are Intel: Core i5-5675C (estimated bottleneck: about 0%), and AMD: Ryzen 3 1300X (about 0%). Below are the top 10 compatible CPUs, CPUs to avoid, and generative AI models supported by this amount of VRAM.
CPUs are ordered by proximity to the ideal CPU:GPU ratio of 0.9:1. A lower bottleneck percentage means more of the GPU’s performance can be used.
The Bottleneck Checker opens with GeForce GTX 980 already selected.
GTX 980 (GTX980 / 980) has a performance score of 8,300 points. Using the same CPU:GPU ≈ 0.9:1 standard as the checker, compatibility by CPU score is shown below.
| Example CPUs to Pair | Rating | What It Means |
|---|---|---|
| Core i7-3770K、Core i5-7600K、AMD FX-8350 | Great Match: 10% or Less | Optimal balance. Nearly all of GTX 980 performance can be used |
| AMD Phenom II X6 1090T、Core i5-3570、Core i5-2500K | Acceptable: 10–25% | Practical with no major issue. Consider a future upgrade if targeting high fps. |
| Core i3-7100、AMD FX-6100、Core i5-4440 | CPU Too Weak: Over 25% | A clear CPU bottleneck. Much of the GPU performance is wasted |
| Ryzen 5 1400、Core i7-6700K、Core i7-4790K | CPU Overkill | Likely overkill for gaming |
Note: Perceived results vary by resolution and game (GPU matters more at 4K, while CPU matters more at high-fps Full HD). For an exact estimate, use the Bottleneck Checker.
Runs Comfortably: Meets recommended VRAM / Barely Runs: Meets minimum VRAM (lower quality or quantization may be needed)

In our estimate, the best-balanced options are Core i5-5675C for Intel (estimated bottleneck: about 0%) and Ryzen 3 1300X for AMD (about 0%). A CPU-to-GPU performance ratio near 0.9:1 tends to use both parts effectively. See the top 10 compatible CPUs in the table on this page.
As a guide, CPUs such as Core i3-7100、AMD FX-6100、Core i5-4440、Core i5-3450 push the bottleneck above 25% and waste much of the GeForce GTX 980 performance. On the other hand, CPUs such as Ryzen 5 1400、Core i7-6700K、Core i7-4790K are likely overkill for gaming.
GeForce GTX 980 has 4GB of VRAM. It can comfortably run about 17 models, including Stable Diffusion and LLMs (for example, SD 1.5 (Q4 quantized), Qwen 2.5 0.5B (Q4), Qwen 2.5 1.5B (Q4)).
GeForce GTX 980 has a power draw (TDP) of 165W. Choose a power supply that covers the GPU TDP plus CPU and other component power draw, with additional headroom. Check the actual CPU pairing balance in the bottleneck diagnosis above.
Its performance score is 8,300 points. CPU balance matters for gaming, while VRAM (4GB) matters for generative AI. Use the top 10 CPU list and AI model list above to check your use case.
