Performance comparison: which is faster?
Radeon RX 6700 XT (AMD, 2021) and Radeon RX 5700 XT (AMD, 2020) are compared here. Compare scores and VRAM, generative AI usability, and CPUs that pair well with each GPU.
Overall performance: RX 6700 XT is about 19.4% faster
For generative AI, the higher-VRAM RX 6700 XT（12GB） 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 6700 XT | RX 5700 XT |
|---|---|---|
| Performance Score | 18,500 | 15,500 |
| VRAM | 12GB | 8GB |
| Manufacturer | AMD | AMD |
| Series | RX 6000 | RX 5000 |
| Release Year | 2021 | 2020 |
| Compatible CPU Example | Core i5-9500 | Ryzen 5 2600 |
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 6700 XT also run here)
| If You Want To... | Recommended |
|---|---|
| Prioritize high fps and smooth performance in demanding games | RX 6700 XT |
| Run larger generative AI and LLM models | RX 6700 XT |
| Prioritize value and adequate performance | RX 5700 XT (the lower model is often sufficient) |
RX 6700 XT is about 19.4% higher by score (RX 6700 XT: 18500 points / RX 5700 XT: 15500 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 6700 XT has 12GB of VRAM, while RX 5700 XT has 8GB; RX 6700 XT has more. If image generation or a local LLM is even a possibility, the higher-VRAM option provides more room.
Using our guideline, Core i5-9500 pairs well with RX 6700 XT and Ryzen 5 2600 with RX 5700 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.
