Performance comparison: which is faster?
Radeon R9 270 (AMD, 2014) and Radeon RX 550 (AMD, 2017) are compared here. Compare scores and VRAM, generative AI usability, and CPUs that pair well with each GPU.
Overall performance: R9 270 is about 16.7% 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 | R9 270 | RX 550 |
|---|---|---|
| Performance Score | 3,500 | 3,000 |
| VRAM | 2GB | 2GB |
| Manufacturer | AMD | AMD |
| Series | R9 | RX 5000 |
| Release Year | 2014 | 2017 |
| Compatible CPU Example | AMD A6-7470K | AMD Phenom II X2 560 |
| If You Want To... | Recommended |
|---|---|
| Prioritize high fps and smooth performance in demanding games | R9 270 |
| Run larger generative AI and LLM models | R9 270 |
| Prioritize value and adequate performance | RX 550 (the lower model is often sufficient) |
R9 270 is about 16.7% higher by score (R9 270: 3500 points / RX 550: 3000 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 A6-7470K pairs well with R9 270 and AMD Phenom II X2 560 with RX 550 (CPU:GPU ≈ 0.9:1). If the CPU is too weak, replacing the GPU may not raise fps, so check the combination before buying.
