Performance comparison: which is faster?
Radeon R9 280X (AMD, 2014) and Radeon R9 280 (AMD, 2014) are compared here. Compare scores and VRAM, generative AI usability, and CPUs that pair well with each GPU.
Overall performance: R9 280X is about 11.1% faster
Both have 3GB 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 | R9 280X | R9 280 |
|---|---|---|
| Performance Score | 5,000 | 4,500 |
| VRAM | 3GB | 3GB |
| Manufacturer | AMD | AMD |
| Series | R9 | R9 |
| Release Year | 2014 | 2014 |
| Compatible CPU Example | AMD A8-7670K | AMD FX-4100 |
| If You Want To... | Recommended |
|---|---|
| Prioritize high fps and smooth performance in demanding games | R9 280X |
| Run larger generative AI and LLM models | R9 280X |
| Prioritize value and adequate performance | R9 280 (the lower model is often sufficient) |
R9 280X is about 11.1% higher by score (R9 280X: 5000 points / R9 280: 4500 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 3GB of VRAM, so the range of generative AI models they can run is nearly the same.
Using our guideline, AMD A8-7670K pairs well with R9 280X and AMD FX-4100 with R9 280 (CPU:GPU ≈ 0.9:1). If the CPU is too weak, replacing the GPU may not raise fps, so check the combination before buying.
