Performance comparison: which is faster?
Radeon RX 6800 XT (AMD, 2020) and AMD Radeon Pro W7800 (AMD, 2023) are compared here. Compare scores and VRAM, generative AI usability, and CPUs that pair well with each GPU.
Overall performance: RX 6800 XT is about 4.5% faster
For generative AI, the higher-VRAM Radeon Pro W7800（32GB） 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 XT | Radeon Pro W7800 |
|---|---|---|
| Performance Score | 23,000 | 22,000 |
| VRAM | 16GB | 32GB |
| Manufacturer | AMD | AMD |
| Series | RX 6000 | Pro |
| Release Year | 2020 | 2023 |
| Compatible CPU Example | Ryzen 7 5800X | Core i5-11600 |
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 Radeon Pro W7800 also run here)
| If You Want To... | Recommended |
|---|---|
| Prioritize high fps and smooth performance in demanding games | RX 6800 XT |
| Run larger generative AI and LLM models | Radeon Pro W7800 |
| Prioritize value and adequate performance | Radeon Pro W7800 (the lower model is often sufficient) |
RX 6800 XT is about 4.5% higher by score (RX 6800 XT: 23000 points / Radeon Pro W7800: 22000 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 XT has 16GB of VRAM, while Radeon Pro W7800 has 32GB; Radeon Pro W7800 has more. If image generation or a local LLM is even a possibility, the higher-VRAM option provides more room.
Using our guideline, Ryzen 7 5800X pairs well with RX 6800 XT and Core i5-11600 with Radeon Pro W7800 (CPU:GPU ≈ 0.9:1). If the CPU is too weak, replacing the GPU may not raise fps, so check the combination before buying.
