Performance comparison: which is faster?
Radeon R9 270X (AMD, 2014) and Radeon RX 460 (AMD, 2016) are compared here. Compare scores and VRAM, generative AI usability, and CPUs that pair well with each GPU.
Overall performance: R9 270X is about 14.3% faster
For generative AI, the higher-VRAM RX 460（4GB） 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 | R9 270X | RX 460 |
|---|---|---|
| Performance Score | 4,000 | 3,500 |
| VRAM | 2GB | 4GB |
| Manufacturer | AMD | AMD |
| Series | R9 | RX 500 |
| Release Year | 2014 | 2016 |
| Compatible CPU Example | AMD Phenom II X4 945 | AMD A6-7470K |
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 460 also run here)
| If You Want To... | Recommended |
|---|---|
| Prioritize high fps and smooth performance in demanding games | R9 270X |
| Run larger generative AI and LLM models | RX 460 |
| Prioritize value and adequate performance | RX 460 (the lower model is often sufficient) |
R9 270X is about 14.3% higher by score (R9 270X: 4000 points / RX 460: 3500 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.
R9 270X has 2GB of VRAM, while RX 460 has 4GB; RX 460 has more. If image generation or a local LLM is even a possibility, the higher-VRAM option provides more room.
Using our guideline, AMD Phenom II X4 945 pairs well with R9 270X and AMD A6-7470K with RX 460 (CPU:GPU ≈ 0.9:1). If the CPU is too weak, replacing the GPU may not raise fps, so check the combination before buying.
