Performance comparison: which is faster?
Radeon R9 380 (AMD, 2015) and Radeon RX 6400 (AMD, 2022) are compared here. Compare scores and VRAM, generative AI usability, and CPUs that pair well with each GPU.
Overall performance: nearly equal
Both have 4GB 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 380 | RX 6400 |
|---|---|---|
| Performance Score | 5,000 | 5,000 |
| VRAM | 4GB | 4GB |
| Manufacturer | AMD | AMD |
| Series | R9 | RX 6000 |
| Release Year | 2015 | 2022 |
| Compatible CPU Example | AMD A8-7670K | AMD A8-7670K |
| If You Want To... | Recommended |
|---|---|
| Prioritize high fps and smooth performance in demanding games | R9 380 |
| Run larger generative AI and LLM models | R9 380 |
| Prioritize value and adequate performance | R9 380 (the lower model is often sufficient) |
Their scores are nearly identical (R9 380: 5000 points / RX 6400: 5000 points). In this case, compare price, VRAM, and power draw.
Both have 4GB 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 380 and AMD A8-7670K with RX 6400 (CPU:GPU ≈ 0.9:1). If the CPU is too weak, replacing the GPU may not raise fps, so check the combination before buying.
