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 712 FPS, suitable for 144Hz+ monitors. At 1440p, all settings exceed 561 FPS. At 4K, all settings exceed 285 FPS.
The GeForce RTX 5090 is 1304% above the recommended GPU (GeForce GTX 560) for League of Legends. The Xeon Platinum 8352Y is 971% above the recommended CPU (Core i5-3330).
At lower resolutions (1080p (low/medium), 1440p low, all 4k settings), the Xeon Platinum 8352Y sets the FPS ceiling. As graphical load increases at (1440p ultra), the GeForce RTX 5090 becomes the FPS-limiting side. The FPS ceiling is closely matched at 1080p (high/ultra), 1440p (medium/high).
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 1440p ultra, the GeForce RTX 5090 sets the ceiling at about 524 FPS, while the Xeon Platinum 8352Y has headroom up to 566 FPS. In this scenario, the GPU limits the CPU potential by 7% (FPS gap: 42 FPS). Overall distribution: GPU limits 2/12 cells, CPU limits 4/12, balanced 6/12. Confidence is low because both ceilings are very close in this cell.
The Xeon Platinum 8352Y and GeForce RTX 5090 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 6% | CPU Limits GPU 6% | Balanced | Balanced |
| 1440p (2K QHD) | CPU Limits GPU 6% | Balanced | Balanced | GPU Limits CPU 7% |
| 4K (Ultra HD) | CPU Limits GPU 6% | Balanced | Balanced | GPU Limits CPU 7% |
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 Xeon Platinum 8352Y paired with the GeForce RTX 5090 can run League of Legends smoothly up to 4k achieving around 285 FPS at Ultra quality. Your GPU is 1304% above the recommended specs, and your CPU is 971% 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.
Your Xeon Platinum 8352Y is already an incredibly powerful processor. While it's technically the first component to hit its limit (which is completely normal in state-of-the-art builds), there is no meaningful upgrade path that would drastically improve your League of Legends performance right now. CPU fully utilized at: 1080p low, 1080p medium, 1440p low, 4k low, 4k medium, 4k high, 4k ultra. GPU fully utilized at: 1440p 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 Xeon Platinum 8352Y and GeForce RTX 5090 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.
