Performance comparison: which is faster?
Radeon RX 9070 (AMD, 2025) and Radeon RX 6900 XT (AMD, 2020) are compared here. Compare scores and VRAM, generative AI usability, and CPUs that pair well with each GPU.
Overall performance: RX 9070 is about 31.3% faster
Both have 16GB 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 9070 | RX 6900 XT |
|---|---|---|
| Performance Score | 31,500 | 24,000 |
| VRAM | 16GB | 16GB |
| Manufacturer | AMD | AMD |
| Series | RX 9000 | RX 6000 |
| Release Year | 2025 | 2020 |
| Compatible CPU Example | Ryzen 9 9950X3D | Ryzen 9 5900X |
| If You Want To... | Recommended |
|---|---|
| Prioritize high fps and smooth performance in demanding games | RX 9070 |
| Run larger generative AI and LLM models | RX 9070 |
| Prioritize value and adequate performance | RX 6900 XT (the lower model is often sufficient) |
RX 9070 is about 31.3% higher by score (RX 9070: 31500 points / RX 6900 XT: 24000 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 16GB of VRAM, so the range of generative AI models they can run is nearly the same.
Using our guideline, Ryzen 9 9950X3D pairs well with RX 9070 and Ryzen 9 5900X with RX 6900 XT (CPU:GPU ≈ 0.9:1). If the CPU is too weak, replacing the GPU may not raise fps, so check the combination before buying.
