Performance comparison: which is faster?
Radeon RX 7900 XT (AMD, 2023) and Radeon RX 7900 GRE (AMD, 2024) are compared here. Compare scores and VRAM, generative AI usability, and CPUs that pair well with each GPU.
Overall performance: RX 7900 XT is about 12.3% faster
For generative AI, the higher-VRAM RX 7900 XT（20GB） has the advantage. 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 7900 XT | RX 7900 GRE |
|---|---|---|
| Performance Score | 32,000 | 28,500 |
| VRAM | 20GB | 16GB |
| Manufacturer | AMD | AMD |
| Series | RX 7000 | RX 7000 |
| Release Year | 2023 | 2024 |
| Compatible CPU Example | Ryzen 9 9950X3D | Ryzen 9 7950X3D |
These generative AI models can run on only one GPU because of the VRAM difference (Stable Diffusion, Flux, LLMs, and others).
— None (all models that run on RX 7900 XT also run here)
| If You Want To... | Recommended |
|---|---|
| Prioritize high fps and smooth performance in demanding games | RX 7900 XT |
| Run larger generative AI and LLM models | RX 7900 XT |
| Prioritize value and adequate performance | RX 7900 GRE (the lower model is often sufficient) |
RX 7900 XT is about 12.3% higher by score (RX 7900 XT: 32000 points / RX 7900 GRE: 28500 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.
RX 7900 XT has 20GB of VRAM, while RX 7900 GRE has 16GB; RX 7900 XT has more. If image generation or a local LLM is even a possibility, the higher-VRAM option provides more room.
Using our guideline, Ryzen 9 9950X3D pairs well with RX 7900 XT and Ryzen 9 7950X3D with RX 7900 GRE (CPU:GPU ≈ 0.9:1). If the CPU is too weak, replacing the GPU may not raise fps, so check the combination before buying.
