Performance comparison: which is faster?
Radeon RX 6800 XT (AMD, 2020) and Radeon RX 7800 XT (AMD, 2023) are compared here. Compare scores and VRAM, generative AI usability, and CPUs that pair well with each GPU.
Overall performance: nearly equal
Both have 16GB of VRAM, so they support a similar range of generative AI models. 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 | RX 7800 XT |
|---|---|---|
| Performance Score | 23,000 | 23,000 |
| VRAM | 16GB | 16GB |
| Manufacturer | AMD | AMD |
| Series | RX 6000 | RX 7000 |
| Release Year | 2020 | 2023 |
| Compatible CPU Example | Ryzen 7 5800X | Ryzen 7 5800X |
| If You Want To... | Recommended |
|---|---|
| Prioritize high fps and smooth performance in demanding games | RX 6800 XT |
| Run larger generative AI and LLM models | RX 6800 XT |
| Prioritize value and adequate performance | RX 6800 XT (the lower model is often sufficient) |
Their scores are nearly identical (RX 6800 XT: 23000 points / RX 7800 XT: 23000 points). In this case, compare price, VRAM, and power draw.
Both have 16GB of VRAM, so the range of generative AI models they can run is nearly the same.
Using our guideline, Ryzen 7 5800X pairs well with RX 6800 XT and Ryzen 7 5800X with RX 7800 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.
