Performance comparison: which is faster?
Radeon RX 5500 XT (AMD, 2020) and Radeon R9 390X (AMD, 2015) are compared here. Compare scores and VRAM, generative AI usability, and CPUs that pair well with each GPU.
Overall performance: RX 5500 XT is about 26.7% faster
Both have 8GB 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 | RX 5500 XT | R9 390X |
|---|---|---|
| Performance Score | 9,500 | 7,500 |
| VRAM | 8GB | 8GB |
| Manufacturer | AMD | AMD |
| Series | RX 5000 | R9 |
| Release Year | 2020 | 2015 |
| Compatible CPU Example | Core i7-3770K | Core i5-3570K |
| If You Want To... | Recommended |
|---|---|
| Prioritize high fps and smooth performance in demanding games | RX 5500 XT |
| Run larger generative AI and LLM models | RX 5500 XT |
| Prioritize value and adequate performance | R9 390X (the lower model is often sufficient) |
RX 5500 XT is about 26.7% higher by score (RX 5500 XT: 9500 points / R9 390X: 7500 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 8GB of VRAM, so the range of generative AI models they can run is nearly the same.
Using our guideline, Core i7-3770K pairs well with RX 5500 XT and Core i5-3570K with R9 390X (CPU:GPU ≈ 0.9:1). If the CPU is too weak, replacing the GPU may not raise fps, so check the combination before buying.
