Best GPUs for this CPU, bottleneck check, and compatible graphics cards
Ryzen 7 3800XT / AMD made / Ryzen 3000 / Released 2020 Also known as: 3800XT / Ryzen73800XT
Ryzen 7 3800XT (AMD, released in 2020, also listed as 3800XT / Ryzen73800XT) is a CPU with a performance score of 27,000, 8C / 16T, TDP 105W. If GPU compatibility and performance balance are poor, a Bottleneck occurs, preventing the GPU or CPU from reaching its full potential. In our estimate, the GPU that pairs best with Ryzen 7 3800XT is Radeon RX 6800 (estimated bottleneck: about 0%). Below are the top 10 compatible GPUs and a guide to GPUs to avoid.
GPUs are ordered by proximity to the ideal CPU:GPU ratio of 0.9:1. A lower bottleneck percentage means the combination can use more of its performance.
If you want higher graphics settings or plan to keep the PC for years, you can pick a GPU one step stronger. Ryzen 7 3800XT will fall slightly behind (a bottleneck of 10% or less), but a later CPU upgrade will let the GPU run at full strength.
The Bottleneck Checker opens with Ryzen 7 3800XT already selected.
Ryzen 7 3800XT (3800XT / Ryzen73800XT) has a performance score of 27,000 points. Using the same CPU:GPU ≈ 0.9:1 standard as the checker, compatibility by GPU score is shown below.
| GPU Score to Pair | Rating | What It Means |
|---|---|---|
| Below 13,852 points | GPU Too Weak | The GPU is too weak for this CPU. Some of Ryzen 7 3800XT performance remains unused (e.g., Radeon RX 6600、GeForce RTX 2070、GeForce RTX 2060 SUPER) |
| 13,852–23,086 points | Great Match: 10% or Less | Optimal balance. Both CPU and GPU can deliver nearly full performance (ideal: about 20,778 pts) |
| 23,086–27,704 points | Acceptable: 10–25% | The GPU is somewhat strong. This is practical, but the CPU may hold it back under heavy load. |
| Over 27,704 points | CPU Bottleneck: Over 25% | The GPU is too powerful for Ryzen 7 3800XT to use fully (e.g., GeForce RTX 5070、GeForce RTX 4070 Ti、Radeon RX 7900 GRE、GeForce RTX 3090 Ti) |
Note: Perceived results vary by resolution and game (GPU matters more at 4K, while CPU matters more at high-fps Full HD). For an exact estimate, use the Bottleneck Checker.

Our estimate finds that Radeon RX 6800 offers the best balance, with an estimated bottleneck of about 0%. A CPU-to-GPU performance ratio near 0.9:1 tends to use both parts effectively. See the top 10 compatible GPUs in the table on this page.
Pairing Ryzen 7 3800XT with a powerful GPU scoring over 27,704 points (for example, GeForce RTX 5070、GeForce RTX 4070 Ti、Radeon RX 7900 GRE、GeForce RTX 3090 Ti) is likely to create a CPU bottleneck above 25%.Conversely, a GPU below 13,852 points（例: Radeon RX 6600、GeForce RTX 2070、GeForce RTX 2060 SUPER） leaves some of Ryzen 7 3800XT performance unused.
Ryzen 7 3800XT has 8 cores and 16 threads.Its base clock is 3.9GHz and maximum boost clock is 4.7GHz.The socket is AM4.
Ryzen 7 3800XT has a TDP of 105W. As a guideline, choose a power supply that covers the CPU TDP plus GPU power draw, with additional headroom.
Its performance score is 27,000 points. CPU–GPU balance matters for games, while core count (8C / 16T) matters for video editing and AI preprocessing. Check the top 10 GPUs above for your use case. GPU VRAM is the main factor for running generative AI, so also see each GPU detail page.
