Best GPUs for this CPU, bottleneck check, and compatible graphics cards
Core i5-1335U / Intel made / 13th Gen / Released 2023 Also known as: i5-1335U / Corei5-1335U
Core i5-1335U (Intel, released in 2023, also listed as i5-1335U / Corei5-1335U) is a CPU with a performance score of 15,000, 10C / 12T, TDP 15W. 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 i5-1335U is GeForce RTX 4050 Laptop GPU (estimated bottleneck: about 0%). Below are the top 5 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.
Core i5-1335U is a laptop CPU. In most laptops the GPU is mounted on the mainboard, so a separate graphics card cannot be added. The list below estimates performance balance with laptop GPUs of a similar class.
If you want higher graphics settings or plan to keep the PC for years, you can pick a GPU one step stronger. Core i5-1335U 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 i5-1335U already selected.
Core i5-1335U (i5-1335U / Corei5-1335U) has a performance score of 15,000 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 11,111 points | GPU Too Weak | The GPU is too weak for this CPU. Some of Core i5-1335U performance remains unused |
| 11,111–18,519 points | Great Match: 10% or Less | Optimal balance. Both CPU and GPU can deliver nearly full performance (ideal: about 16,667 pts) |
| 18,519–22,222 points | Acceptable: 10–25% | The GPU is somewhat strong. This is practical, but the CPU may hold it back under heavy load. |
| Over 22,222 points | CPU Bottleneck: Over 25% | The GPU is too powerful for Core i5-1335U to use fully (e.g., GeForce RTX 4090 Laptop GPU) |
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 GeForce RTX 4050 Laptop GPU 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 5 compatible GPUs in the table on this page.
Pairing Core i5-1335U with a powerful GPU scoring over 22,222 points (for example, GeForce RTX 4090 Laptop GPU) is likely to create a CPU bottleneck above 25%.Conversely, a GPU below 11,111 points leaves some of Core i5-1335U performance unused.
Core i5-1335U has 10 cores and 12 threads.Its base clock is 1.3GHz and maximum boost clock is 4.6GHz.The socket is BGA.
Core i5-1335U has a TDP of 15W. As a guideline, choose a power supply that covers the CPU TDP plus GPU power draw, with additional headroom.
Its performance score is 15,000 points. CPU–GPU balance matters for games, while core count (10C / 12T) matters for video editing and AI preprocessing. Check the top 5 GPUs above for your use case. GPU VRAM is the main factor for running generative AI, so also see each GPU detail page.
