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 410 FPS, suitable for 144Hz+ monitors. At 1440p, all settings exceed 354 FPS. At 4K, all settings exceed 241 FPS.
The GeForce RTX 4090 is 1277% above the recommended GPU (GeForce GTX 560) for League of Legends. The Ryzen 5 PRO 230 is 208% above the recommended CPU (Core i5-3330).
The Ryzen 5 PRO 230 sets the FPS ceiling at 1080p (low/medium), 1440p low, 4k (low/medium), while the GeForce RTX 4090 still has headroom. The FPS ceiling is closely matched at 1080p (high/ultra), 1440p (medium/high/ultra), 4k (high/ultra).
Approximated average price on current market:
Combo price: $1799. At 1080p Ultra, this combo delivers 410 FPS, equivalent to 0.23 FPS per dollar.

This section is based on estimated CPU/GPU FPS ceilings, not utilization percentages.
At 1080p low, the Ryzen 5 PRO 230 sets the ceiling at about 493 FPS, while the GeForce RTX 4090 could reach 700 FPS. In this scenario, the CPU limits the GPU potential by 30% (FPS gap: 207 FPS). Overall distribution: CPU limits 5/12 cells, GPU limits 0/12, balanced 7/12.
The Ryzen 5 PRO 230 and GeForce RTX 4090 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 30% | CPU Limits GPU 14% | Balanced | Balanced |
| 1440p (2K QHD) | CPU Limits GPU 23% | Balanced | Balanced | Balanced |
| 4K (Ultra HD) | CPU Limits GPU 6% | CPU Limits GPU 7% | Balanced | Balanced |
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 5 PRO 230 paired with the GeForce RTX 4090 can run League of Legends smoothly up to 4k achieving around 241 FPS at Ultra quality. Your GPU is 1277% above the recommended specs, and your CPU is 208% above the recommended requirements.
This CPU + GPU combo costs approximately $1799 ($150 CPU + $1649 GPU). Since the CPU is the main limiting factor, investing in a stronger processor will improve your framerates and overall value. For example, the Ryzen 9 7845HX is a great upgrade option (Rank #1 for value).
For League of Legends, upgrading the CPU would have the biggest impact on performance. The Ryzen 5 PRO 230 is currently the limiting factor — the GeForce RTX 4090 has extra headroom that a faster processor could take advantage of. This is especially noticeable at 1080p where CPU performance matters more. CPU-limited at: 1080p low, 1080p medium, 1440p low, 4k low, 4k medium.
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 5 PRO 230 and GeForce RTX 4090 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.
