Performance comparison: which is faster?
Radeon RX 6800 (AMD, 2020) and Radeon RX 6750 XT (AMD, 2022) are compared here. Compare scores and VRAM, generative AI usability, and CPUs that pair well with each GPU.
Overall performance: RX 6800 is about 5.1% faster
For generative AI, the higher-VRAM RX 6800（16GB） 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 6800 | RX 6750 XT |
|---|---|---|
| Performance Score | 20,500 | 19,500 |
| VRAM | 16GB | 12GB |
| Manufacturer | AMD | AMD |
| Series | RX 6000 | RX 6000 |
| Release Year | 2020 | 2022 |
| Compatible CPU Example | Core i3-12100 | Ryzen 9 3900X |
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 6800 also run here)
| If You Want To... | Recommended |
|---|---|
| Prioritize high fps and smooth performance in demanding games | RX 6800 |
| Run larger generative AI and LLM models | RX 6800 |
| Prioritize value and adequate performance | RX 6750 XT (the lower model is often sufficient) |
RX 6800 is about 5.1% higher by score (RX 6800: 20500 points / RX 6750 XT: 19500 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 6800 has 16GB of VRAM, while RX 6750 XT has 12GB; RX 6800 has more. If image generation or a local LLM is even a possibility, the higher-VRAM option provides more room.
Using our guideline, Core i3-12100 pairs well with RX 6800 and Ryzen 9 3900X with RX 6750 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.
