League of Legends benchmark on RX 6400: FPS by resolution and quality
Pick yours and we recalculate the whole table above with it.
League of Legends FPS with a RX 6400 and a Intel Core i5-13400
| Quality | 1080p (Full HD) | 1440p (2K) | 4K (Ultra HD) |
|---|---|---|---|
| Ultra | 91FPS min 62Good | 51FPS min 45Acceptable | 16FPS min 14Poor |
| High | 119FPS min 81Good | 67FPS min 59Good | 21FPS min 19Poor |
| Medium | 155FPS min 105Excellent | 87FPS min 76Good | 27FPS min 24Poor |
| Low | 201FPS min 136Excellent | 113FPS min 99Good | 35FPS min 31Acceptable |
| Bottleneck (estimated) | CPU 33% | GPU 18% | GPU 75% |
The percentage estimates how much of the stronger component's capability goes unused because of the other one.
This one does matter: from the Intel Core i9-14900K downwards the processor becomes the brake on the RX 6400. There is 36% between the slowest and fastest CPU in the table. One caveat: this is at 1080p, where the CPU weighs most. At 1440p and 4K the graphics card takes over and the processor stops mattering.
FSR performance: FPS with AI upscaling
Upscaling renders League of Legends at a lower internal resolution and reconstructs the image, so you trade a little sharpness for extra frames. These are the estimated figures for the RX 6400 with FSR enabled, starting from its native Ultra FPS.
| Resolution | Native | FSR Quality | FSR Performance |
|---|---|---|---|
| 1080p | 91 | 114 | 132 |
| 1440p | 51 | 69 | 84 |
| 4K | 16 | 23 | 30 |
About ray tracing: every figure on this page is with ray tracing off. The RX 6400 does have dedicated hardware for it, so you can turn it on in games that implement it. The FPS cost swings widely depending on how much ray tracing each title uses, and FSR is exactly what people lean on to pay for it.
Estimated figures. The real gain varies by game and by the version of the technology.
Is the CPU or the graphics card holding you back?
These FPS assume a mid-range CPU that isn't a bottleneck — roughly a Intel Core i5-13400 — and 16 GB of RAM.
With that CPU, the RX 6400 has headroom to spare in League of Legends: the processor runs out before the graphics card does. A faster processor would gain you FPS; a stronger graphics card would barely help. At 4K it flips: there the graphics card becomes the limit.
Is the RX 6400 Enough for League of Legends?
The RX 6400 delivers 91 FPS at 1080p Ultra in League of Legends. Enough for a smooth 60 FPS experience. For 144Hz, lower the quality to High.
At 1440p it gets 51 FPS and at 4K 16 FPS at Ultra quality.
