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 68 FPS. At 1440p, frame rates range from 51 to 101 FPS. At 4K, frame rates range from 34 to 68 FPS.
The Radeon Steam Deck 8CU is 8% above the recommended GPU (GeForce GTX 560) for League of Legends. The Ryzen 7 7800X3D is 435% above the recommended CPU (Core i5-3330).
The Radeon Steam Deck 8CU 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 Radeon Steam Deck 8CU sets the ceiling at about 51 FPS, while the Ryzen 7 7800X3D has headroom up to 450 FPS. In this scenario, the GPU limits the CPU potential by 89% (FPS gap: 399 FPS). Overall distribution: GPU limits 12/12 cells, CPU limits 0/12, balanced 0/12.
Your Radeon Steam Deck 8CU 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 81% | GPU Limits CPU 82% | GPU Limits CPU 82% | GPU Limits CPU 85% |
| 1440p (2K QHD) | GPU Limits CPU 86% | GPU Limits CPU 87% | GPU Limits CPU 86% | GPU Limits CPU 89% |
| 4K (Ultra HD) | GPU Limits CPU 88% | GPU Limits CPU 88% | GPU Limits CPU 88% | GPU Limits CPU 89% |
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.

Yes, the Ryzen 7 7800X3D paired with the Radeon Steam Deck 8CU can run League of Legends smoothly up to 1080p achieving around 68 FPS at Ultra quality. Your GPU is 8% above the recommended specs, and your CPU is 435% above the recommended requirements.
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 Radeon Steam Deck 8CU 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 Ryzen 7 7800X3D and Radeon Steam Deck 8CU 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.
