Best GPUs for this CPU, bottleneck check, and compatible graphics cards
Core i7-5775C / Intel made / 5th Gen / Released 2015 Also known as: i7-5775C / Corei7-5775C
Core i7-5775C (Intel, released in 2015, also listed as i7-5775C / Corei7-5775C) is a CPU with a performance score of 9,500, 4C / 8T, 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 Core i7-5775C is Intel Arc A580 8GB (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. Core i7-5775C 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 Core i7-5775C already selected.
Core i7-5775C (i7-5775C / Corei7-5775C) has a performance score of 9,500 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 7,037 points | GPU Too Weak | The GPU is too weak for this CPU. Some of Core i7-5775C performance remains unused (e.g., GeForce GTX 1650、Radeon RX 480、GeForce GTX 970) |
| 7,037–11,728 points | Great Match: 10% or Less | Optimal balance. Both CPU and GPU can deliver nearly full performance (ideal: about 10,556 pts) |
| 11,728–14,074 points | Acceptable: 10–25% | The GPU is somewhat strong. This is practical, but the CPU may hold it back under heavy load. |
| Over 14,074 points | CPU Bottleneck: Over 25% | The GPU is too powerful for Core i7-5775C to use fully (e.g., Intel Arc B570、GeForce GTX 1080 Ti、Radeon RX 7600 XT、Radeon RX 6600 XT) |
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 Intel Arc A580 8GB 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 Core i7-5775C with a powerful GPU scoring over 14,074 points (for example, Intel Arc B570、GeForce GTX 1080 Ti、Radeon RX 7600 XT、Radeon RX 6600 XT) is likely to create a CPU bottleneck above 25%.Conversely, a GPU below 7,037 points（例: GeForce GTX 1650、Radeon RX 480、GeForce GTX 970） leaves some of Core i7-5775C performance unused.
Core i7-5775C has 4 cores and 8 threads.Its base clock is 3.3GHz and maximum boost clock is 3.7GHz.The socket is LGA1150.
Core i7-5775C 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 9,500 points. CPU–GPU balance matters for games, while core count (4C / 8T) 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.
