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

This section is based on estimated CPU/GPU FPS ceilings, not utilization percentages.
At 4k ultra, the Arc B580 sets the ceiling at about 180 FPS, while the Ryzen 7 7800X3D has headroom up to 315 FPS. In this scenario, the GPU limits the CPU potential by 43% (FPS gap: 135 FPS). Overall distribution: GPU limits 11/12 cells, CPU limits 0/12, balanced 1/12.
Your Arc B580 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) | Balanced | GPU Limits CPU 9% | GPU Limits CPU 13% | GPU Limits CPU 20% |
| 1440p (2K QHD) | GPU Limits CPU 23% | GPU Limits CPU 28% | GPU Limits CPU 28% | GPU Limits CPU 40% |
| 4K (Ultra HD) | GPU Limits CPU 37% | GPU Limits CPU 39% | GPU Limits CPU 39% | GPU Limits CPU 43% |
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 + Arc B580 pairing runs this title with CPU utilization between 0% and 24% and GPU utilization between 2% and 37%. Ryzen 7 7800X3D keeps significant headroom across presets, while Arc B580 is utilized efficiently without persistent saturation. As resolution scales, average GPU load rises from 9% at 1080p to 26% at 4K, while CPU averages move from 13% to 12%.
Neither component is close to saturation: CPU tops out at 24% and GPU at 37%. This pattern suggests possible engine-side limits, an FPS cap, or workload constraints unrelated to raw hardware throughput. It also shows why low utilization does not automatically mean there is no FPS limiter.
At 1080p, averages sit around CPU 13% and GPU 9%. At 1440p, that shifts to CPU 13% and GPU 11%, and at 4K it reaches CPU 12% and GPU 26%. This shows that GPU demand scales sharply with resolution while CPU load remains comparatively stable.
4K (Ultra HD) Low is the most balanced preset based on this dataset. It runs around CPU 7% (0-14%) and GPU 26% (16-35%), which keeps Arc B580 well utilized without constant max-out behavior while Ryzen 7 7800X3D remains stable for consistent frame delivery.
Current utilization does not show an urgent upgrade requirement for either component; the Ryzen 7 7800X3D and Arc B580 remain reasonably matched for this title.
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.

Yes, the Ryzen 7 7800X3D paired with the Arc B580 can run League of Legends smoothly up to 4k achieving around 180 FPS at Ultra quality. Your GPU is 477% above the recommended specs, and your CPU is 435% above the recommended requirements.
This CPU + GPU combo costs approximately $633 ($384 CPU (Rank #212 Value) + $249 GPU (Rank #14 Value)). Your build is already very cost-efficient, but if you want even more FPS, the next good option is upgrading the GPU. For example, upgrading to the GeForce RTX 5060 for around $299 (Rank #2 for value) could deliver noticeably better performance.
For League of Legends, upgrading the GPU would give you the most noticeable improvement. The Arc B580 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 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 Ryzen 7 7800X3D and Arc B580 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.
