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, frame rates range from 26 to 52 FPS depending on quality settings. At 1440p, frame rates range from 20 to 39 FPS. At 4K, frame rates range from 13 to 26 FPS.
The Quadro K620M is 58% below recommended, but 108% above minimum for League of Legends. The Ryzen 7 7800X3D is 435% above the recommended CPU (Core i5-3330).
The Quadro K620M sets the FPS ceiling at all 1080p settings, all 1440p settings, all 4k settings, while the Ryzen 7 7800X3D still has additional frame-generation headroom.
This section is based on estimated CPU/GPU FPS ceilings, not utilization percentages.
At 1440p ultra, the Quadro K620M sets the ceiling at about 20 FPS, while the Ryzen 7 7800X3D has headroom up to 450 FPS. In this scenario, the GPU limits the CPU potential by 96% (FPS gap: 430 FPS). Overall distribution: GPU limits 12/12 cells, CPU limits 0/12, balanced 0/12.
Your Quadro K620M is the limiting side in the heaviest mismatch. This means part of the Ryzen 7 7800X3D frame-generation potential remains unused in those settings.
| Resolution | Low | Medium | High | Ultra |
|---|---|---|---|---|
| 1080p (Full HD) | GPU Limits CPU 93% | GPU Limits CPU 93% | GPU Limits CPU 93% | GPU Limits CPU 94% |
| 1440p (2K QHD) | GPU Limits CPU 94% | GPU Limits CPU 95% | GPU Limits CPU 95% | GPU Limits CPU 96% |
| 4K (Ultra HD) | GPU Limits CPU 95% | GPU Limits CPU 96% | GPU Limits CPU 96% | GPU Limits CPU 96% |
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, not generic utilization heuristics.

The Ryzen 7 7800X3D + Quadro K620M pairing runs this title with CPU utilization between 4% and 19% and GPU utilization between 77% and 100%. Ryzen 7 7800X3D keeps significant headroom across presets, while Quadro K620M carries most of the graphics load at heavier visual settings. As resolution scales, average GPU load rises from 94% at 1080p to 92% at 4K, while CPU averages move from 12% to 11%.
From a utilization perspective, this is a GPU-heavy load profile. At 1440p (2K QHD) Ultra, the Quadro K620M averages 98% usage (95-100%), while the Ryzen 7 7800X3D stays at 12% (5-18%). This shows the graphics pipeline is carrying most of the workload, but utilization alone does not define the FPS limiter.
At 1080p, averages sit around CPU 12% and GPU 94%. At 1440p, that shifts to CPU 12% and GPU 96%, and at 4K it reaches CPU 11% and GPU 92%. This shows that workload scaling is limited, which can indicate engine-side constraints.
1080p (Full HD) Low is the most balanced preset based on this dataset. It runs around CPU 12% (6-17%) and GPU 88% (82-95%), which keeps Quadro K620M well utilized without constant max-out behavior while Ryzen 7 7800X3D remains stable for consistent frame delivery.
Upgrade priority should be the GPU. The Quadro K620M reaches 98% average load at 1440p (2K QHD) Ultra while the Ryzen 7 7800X3D still has headroom, so a faster graphics card would deliver the largest uplift.
Understanding Hardware Utilization: These percentages represent how much of your component's maximum processing power is actively being used during gameplay. They describe hardware load, but they do not directly tell you which component sets the FPS ceiling.
Important: a CPU or GPU can still be the FPS limiter without reaching 100% utilization. Two processors can both show 40% usage and still deliver very different frame rates, depending on per-core speed, cache, engine threading, driver overhead, and frame preparation efficiency.

The Ryzen 7 7800X3D and Quadro K620M will struggle to run League of Legends at smooth framerates. At 1080p Ultra, you can expect around 26 FPS which is classified as "struggling". Consider lowering settings or upgrading your hardware.
Price data is not currently available for this combination. In general, look for setups where the CPU and GPU are balanced — this ensures you're not overspending on one component that the other can't keep up with.
For League of Legends, upgrading the GPU would give you the most noticeable improvement. The Quadro K620M is the limiting factor here, while the Ryzen 7 7800X3D still has spare capacity. A more powerful GPU would unlock higher FPS, especially at higher resolutions and quality presets. GPU-limited at: 1080p low, 1080p medium, 1080p high, 1080p ultra, 1440p low, 1440p medium, 1440p high, 1440p ultra, 4k low, 4k medium, 4k high, 4k ultra.
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 setup meets the minimum requirements but falls short of the recommended specs. You may need to lower some settings for smooth performance.
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.
