Performance comparison: which is faster?
Radeon RX 6500 XT (AMD, 2022) 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: RX 6500 XT is about 16% faster
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 | RX 6500 XT | RX 6400 |
|---|---|---|
| Performance Score | 5,800 | 5,000 |
| VRAM | 4GB | 4GB |
| Manufacturer | AMD | AMD |
| Series | RX 6000 | RX 6000 |
| Release Year | 2022 | 2022 |
| Compatible CPU Example | Core i3-6100 | AMD A8-7670K |
| If You Want To... | Recommended |
|---|---|
| Prioritize high fps and smooth performance in demanding games | RX 6500 XT |
| Run larger generative AI and LLM models | RX 6500 XT |
| Prioritize value and adequate performance | RX 6400 (the lower model is often sufficient) |
RX 6500 XT is about 16% higher by score (RX 6500 XT: 5800 points / RX 6400: 5000 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 4GB of VRAM, so the range of generative AI models they can run is nearly the same.
Using our guideline, Core i3-6100 pairs well with RX 6500 XT 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.
