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 432 FPS, suitable for 144Hz+ monitors. At 1440p, all settings exceed 374 FPS. At 4K, all settings exceed 249 FPS.
The GeForce RTX 3070 is 701% above the recommended GPU (GeForce GTX 560) for League of Legends. The Core i5-12600K is 331% above the recommended CPU (Core i5-3330).
At lower resolutions (1080p low), the Core i5-12600K sets the FPS ceiling. As graphical load increases at (1440p ultra, 4k (medium/high/ultra)), the GeForce RTX 3070 becomes the FPS-limiting side. The FPS ceiling is closely matched at 1080p (medium/high/ultra), 1440p (low/medium/high), 4k low.
Approximated average price on current market:
Combo price: $385. At 1080p Ultra, this combo delivers 432 FPS, equivalent to 1.12 FPS per dollar.
| Resolution | Low | Medium | High | Ultra |
|---|---|---|---|---|
| 1080p | 1.792 fps/$ | 1.579 fps/$ | 1.335 fps/$ | 1.122 fps/$ |
| 1440p | 1.743 fps/$ | 1.418 fps/$ | 1.184 fps/$ | 0.971 fps/$ |
| 4k | 1.236 fps/$ | 1.026 fps/$ | 0.865 fps/$ | 0.647 fps/$ |

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.
At 4k ultra, the GeForce RTX 3070 sets the ceiling at about 249 FPS, while the Core i5-12600K has headroom up to 332 FPS. In this scenario, the GPU limits the CPU potential by 25% (FPS gap: 83 FPS). Overall distribution: GPU limits 4/12 cells, CPU limits 1/12, balanced 7/12.
The Core i5-12600K and GeForce RTX 3070 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) | CPU Limits GPU 14% | Balanced | Balanced | Balanced |
| 1440p (2K QHD) | Balanced | Balanced | Balanced | GPU Limits CPU 15% |
| 4K (Ultra HD) | Balanced | GPU Limits CPU 9% | GPU Limits CPU 15% | GPU Limits CPU 25% |
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 Core i5-12600K paired with the GeForce RTX 3070 can run League of Legends smoothly up to 4k achieving around 249 FPS at Ultra quality. Your GPU is 701% above the recommended specs, and your CPU is 331% above the recommended requirements.
This CPU + GPU combo costs approximately $385 ($185 CPU + $200 GPU). Since the GPU is the main limiting factor, investing in a stronger GPU will improve your framerates and overall value. For example, upgrading to the GeForce RTX 4070 Ti for around $799 (Rank #248 for value) could deliver noticeably better performance.
For League of Legends, upgrading the GPU would give you the most noticeable improvement. The GeForce RTX 3070 is the limiting factor here, while the Core i5-12600K still has spare capacity. A more powerful GPU would unlock higher FPS, especially at higher resolutions and quality presets. GPU-limited at: 1440p ultra, 4k medium, 4k high, 4k ultra. CPU-limited at: 1080p low.
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 Core i5-12600K and GeForce RTX 3070 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.
