Best GPUs for this CPU, bottleneck check, and compatible graphics cards
AMD A8-7670K / AMD made / A-Series / Released 2015 Also known as: 7670K / A8-7670K
AMD A8-7670K (AMD, released in 2015, also listed as 7670K / A8-7670K) is a CPU with a performance score of 4,500, 4C / 4T, TDP 65W. 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 AMD A8-7670K is Radeon RX 6400 (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. AMD A8-7670K 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 AMD A8-7670K already selected.
AMD A8-7670K (7670K / A8-7670K) has a performance score of 4,500 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 3,333 points | GPU Too Weak | The GPU is too weak for this CPU. Some of AMD A8-7670K performance remains unused (e.g., GeForce GTX 1030、Radeon R7 370、Radeon HD 6870) |
| 3,333–5,556 points | Great Match: 10% or Less | Optimal balance. Both CPU and GPU can deliver nearly full performance (ideal: about 5,000 pts) |
| 5,556–6,667 points | Acceptable: 10–25% | The GPU is somewhat strong. This is practical, but the CPU may hold it back under heavy load. |
| Over 6,667 points | CPU Bottleneck: Over 25% | The GPU is too powerful for AMD A8-7670K to use fully (e.g., GeForce GTX 1650、Radeon RX 480、GeForce GTX 970、Radeon R9 390) |
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 6400 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 AMD A8-7670K with a powerful GPU scoring over 6,667 points (for example, GeForce GTX 1650、Radeon RX 480、GeForce GTX 970、Radeon R9 390) is likely to create a CPU bottleneck above 25%.Conversely, a GPU below 3,333 points（例: GeForce GTX 1030、Radeon R7 370、Radeon HD 6870） leaves some of AMD A8-7670K performance unused.
AMD A8-7670K has 4 cores and 4 threads.Its base clock is 3.6GHz and maximum boost clock is 3.9GHz.The socket is FM2+.
AMD A8-7670K has a TDP of 65W. As a guideline, choose a power supply that covers the CPU TDP plus GPU power draw, with additional headroom.
Its performance score is 4,500 points. CPU–GPU balance matters for games, while core count (4C / 4T) 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.
