Performance comparison: which is faster?
Radeon RX 480 (AMD, 2016) and Radeon R9 290X (AMD, 2014) are compared here. Compare scores and VRAM, generative AI usability, and CPUs that pair well with each GPU.
Overall performance: RX 480 is about 7.7% faster
For generative AI, the higher-VRAM RX 480（8GB） 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 | RX 480 | R9 290X |
|---|---|---|
| Performance Score | 7,000 | 6,500 |
| VRAM | 8GB | 4GB |
| Manufacturer | AMD | AMD |
| Series | RX 500 | R9 |
| Release Year | 2016 | 2014 |
| Compatible CPU Example | Ryzen 3 1200 | AMD Phenom II X6 1090T |
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 RX 480 also run here)
| If You Want To... | Recommended |
|---|---|
| Prioritize high fps and smooth performance in demanding games | RX 480 |
| Run larger generative AI and LLM models | RX 480 |
| Prioritize value and adequate performance | R9 290X (the lower model is often sufficient) |
RX 480 is about 7.7% higher by score (RX 480: 7000 points / R9 290X: 6500 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.
RX 480 has 8GB of VRAM, while R9 290X has 4GB; RX 480 has more. If image generation or a local LLM is even a possibility, the higher-VRAM option provides more room.
Using our guideline, Ryzen 3 1200 pairs well with RX 480 and AMD Phenom II X6 1090T with R9 290X (CPU:GPU ≈ 0.9:1). If the CPU is too weak, replacing the GPU may not raise fps, so check the combination before buying.
