Performance comparison: which is faster?
Radeon RX 7700 XT (AMD, 2023) and Radeon RX 6700 (AMD, 2022) are compared here. Compare scores and VRAM, generative AI usability, and CPUs that pair well with each GPU.
Overall performance: RX 7700 XT is about 17.6% faster
For generative AI, the higher-VRAM RX 7700 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 7700 XT | RX 6700 |
|---|---|---|
| Performance Score | 20,000 | 17,000 |
| VRAM | 12GB | 10GB |
| Manufacturer | AMD | AMD |
| Series | RX 7000 | RX 6000 |
| Release Year | 2023 | 2022 |
| Compatible CPU Example | Core i7-9700 | Ryzen 5 2600X |
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 7700 XT also run here)
| If You Want To... | Recommended |
|---|---|
| Prioritize high fps and smooth performance in demanding games | RX 7700 XT |
| Run larger generative AI and LLM models | RX 7700 XT |
| Prioritize value and adequate performance | RX 6700 (the lower model is often sufficient) |
RX 7700 XT is about 17.6% higher by score (RX 7700 XT: 20000 points / RX 6700: 17000 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 7700 XT has 12GB of VRAM, while RX 6700 has 10GB; RX 7700 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 i7-9700 pairs well with RX 7700 XT and Ryzen 5 2600X with RX 6700 (CPU:GPU ≈ 0.9:1). If the CPU is too weak, replacing the GPU may not raise fps, so check the combination before buying.
