As the world's most popular MOBA, League of Legends runs on a proprietary engine that has been updated for over a decade. Recently, Riot increased the minimum requirements to include AVX instruction support and dropped support for older OSs and DirectX 9. While still lightweight, modern team fights with complex particle effects can strain older integrated graphics. The game scales well with single-thread CPU performance, meaning even modern entry-level processors can deliver high frame rates.
Actual FPS may vary based on RAM speed, background processes, and other system factors
Performance Report
At 1080p, all quality settings exceed 398 FPS, suitable for 144Hz+ monitors. At 1440p, all settings exceed 338 FPS. At 4K, all settings exceed 261 FPS.
The GeForce RTX 4090 is 1277% above the recommended GPU (GeForce GTX 560) for League of Legends. The Ryzen 9 7950X is 873% above the recommended CPU (Core i5-3330).
No major FPS-ceiling mismatch detected. The GeForce RTX 4090 and Ryzen 9 7950X stay close in effective frame-generation ceiling across the tested resolutions and quality settings.
Approximated average price on current market:
Combo price: $2187.04. At 1080p Ultra, this combo delivers 398 FPS, equivalent to 0.18 FPS per dollar.
| Resolution | Low | Medium | High | Ultra |

This section is based on estimated CPU/GPU FPS ceilings, not utilization percentages. Adjacent heavier settings are lightly stabilized to remove prediction jitter that would otherwise create impossible reversals.
This CPU/GPU pair is mostly balanced in League of Legends. Across tested presets: GPU limits in 0/12, CPU limits in 0/12, and balanced in 12/12. Peak observed performance in the sampled cells is around 733 FPS.
The Ryzen 9 7950X and GeForce RTX 4090 stay close in effective frame-generation ceiling across most presets, so neither side consistently suppresses the other by a large margin.
| Resolution | Low | Medium | High | Ultra |
|---|---|---|---|---|
| 1080p (Full HD) | Balanced | Balanced | Balanced | Balanced |
| 1440p (2K QHD) | Balanced | Balanced | Balanced | Balanced |
| 4K (Ultra HD) | Balanced | Balanced | Balanced | Balanced |
We estimate the maximum FPS the processor can sustain and the maximum FPS the graphics card can sustain in each setting, then compare those limits directly.
Limit Factor formula: (stronger - weaker) / stronger. Example: if CPU ceiling is 200 FPS and GPU ceiling is 140 FPS, then GPU limits CPU by 30%.
CPU Limits GPU means the processor ceiling is lower. GPU Limits CPU means the graphics ceiling is lower. Balanced means the FPS ceilings are close enough that the gap is negligible.
A component can still be the FPS limiter without reaching 100% utilization. The displayed percentages are derived from FPS ceilings and then monotonic-smoothed across heavier presets and resolutions, not generic utilization heuristics.

Yes, the Ryzen 9 7950X paired with the GeForce RTX 4090 can run League of Legends smoothly up to 4k achieving around 261 FPS at Ultra quality. Your GPU is 1277% above the recommended specs, and your CPU is 873% above the recommended requirements.
This CPU + GPU combo costs approximately $2187.04 ($538.04 CPU + $1649 GPU). This is a well-balanced setup, meaning you're getting good value from both components without significant waste.
This setup is already well-balanced for League of Legends. No significant bottleneck - CPU and GPU are well matched across all settings. Both the Ryzen 9 7950X and GeForce RTX 4090 complement each other effectively, so upgrading either component individually would yield diminishing returns. If you want more FPS, you'd benefit most from upgrading both CPU and GPU together.
League of Legends does not currently support Frame Generation technologies like DLSS 3 or FSR 3. Your performance is based entirely on native rendering. If the game adds support in a future update, newer GPUs will benefit the most.
League of Legends requires at minimum a Core i3-530 (CPU) and GeForce 9600 GT (GPU) with 2 GB RAM and 16 GB storage. For the recommended experience, you need a Core i5-3330 and GeForce GTX 560 with 4 GB RAM. Your Ryzen 9 7950X and GeForce RTX 4090 both exceed the recommended specs, so you're well-positioned for a great experience.
These League of Legends FPS results are not arbitrary numbers. They come from calculations informed by thousands of real gaming benchmarks, and the typical accuracy range is around 10% to 15%. That makes them far more useful than generic FPS calculators that simply invent values without a benchmark foundation. Actual in-game performance can still vary with drivers, updates, RAM configuration, cooling, and the exact scene being rendered.
Performance estimates are based on synthetic benchmarks and hardware capabilities.
Results may vary based on drivers, OS, and background processes.
