League of Legends benchmark on R9 390X: FPS by resolution and quality
Pick yours and we recalculate the whole table above with it.
League of Legends FPS with a R9 390X and a Intel Core i5-13400
| Quality | 1080p (Full HD) | 1440p (2K) | 4K (Ultra HD) |
|---|---|---|---|
| Ultra | 115FPS min 71Good | 68FPS min 54Good | 28FPS min 25Poor |
| High | 150FPS min 93Excellent | 89FPS min 71Good | 36FPS min 32Acceptable |
| Medium | 196FPS min 122Excellent | 116FPS min 92Good | 47FPS min 42Acceptable |
| Low | 254FPS min 158Excellent | 150FPS min 119Excellent | 61FPS min 54Good |
| Bottleneck (estimated) | CPU 43% | CPU 13% | GPU 56% |
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 R9 390X. There is 27% 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 R9 390X with FSR enabled, starting from its native Ultra FPS.
| Resolution | Native | FSR Quality | FSR Performance |
|---|---|---|---|
| 1080p | 115 | 144 | 167 |
| 1440p | 68 | 92 | 112 |
| 4K | 28 | 41 | 52 |
About ray tracing: every figure on this page is with ray tracing off. The R9 390X has no dedicated hardware for it, so it is an option best left disabled.
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 R9 390X 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 R9 390X Enough for League of Legends?
The R9 390X delivers 115 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 68 FPS and at 4K 28 FPS at Ultra quality.
