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 422 FPS, suitable for 144Hz+ monitors. At 1440p, all settings exceed 288 FPS. At 4K, all settings exceed 170 FPS.
The GeForce RTX 4090 is 1277% above the recommended GPU (GeForce GTX 560) for League of Legends. The Ryzen Threadripper 1920X is 261% above the recommended CPU (Core i5-3330).

This section is based on estimated CPU/GPU FPS ceilings, not utilization percentages.
At 4k medium, the Ryzen Threadripper 1920X sets the ceiling at about 262 FPS, while the GeForce RTX 4090 could reach 319 FPS. In this scenario, the CPU limits the GPU potential by 18% (FPS gap: 57 FPS). Overall distribution: CPU limits 7/12 cells, GPU limits 3/12, balanced 2/12.
Your Ryzen Threadripper 1920X is the limiting side in the heaviest mismatch. This means part of the GeForce RTX 4090 rendering potential remains unused in those settings.
| Resolution | Low | Medium | High | Ultra |
|---|---|---|---|---|
| 1080p (Full HD) | CPU Limits GPU 12% | GPU Limits CPU 7% | GPU Limits CPU 12% | GPU Limits CPU 11% |
| 1440p (2K QHD) | CPU Limits GPU 15% | CPU Limits GPU 9% | Balanced | Balanced |
| 4K (Ultra HD) | CPU Limits GPU 17% | CPU Limits GPU 18% | CPU Limits GPU 17% | CPU Limits GPU 15% |
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 Threadripper 1920X + GeForce RTX 4090 pairing runs this title with CPU utilization between 7% and 36% and GPU utilization between 36% and 71%. Ryzen Threadripper 1920X keeps significant headroom across presets, while GeForce RTX 4090 is utilized efficiently without persistent saturation. As resolution scales, average GPU load rises from 38% at 1080p to 68% at 4K, while CPU averages move from 22% to 16%.
The utilization pattern is relatively even. The GeForce RTX 4090 reaches 70% average at its highest-load preset, while the Ryzen Threadripper 1920X peaks at 24% average. This suggests a fairly controlled load distribution, but the actual FPS-limiting side should still be read from the limiter analysis above.
At 1080p, averages sit around CPU 22% and GPU 38%. At 1440p, that shifts to CPU 16% and GPU 42%, and at 4K it reaches CPU 16% and GPU 68%. This shows that GPU demand scales sharply with resolution while CPU load remains comparatively stable.
4K (Ultra HD) Ultra is the most balanced preset based on this dataset. It runs around CPU 16% (11-22%) and GPU 70% (70-71%), which keeps GeForce RTX 4090 well utilized without constant max-out behavior while Ryzen Threadripper 1920X remains stable for consistent frame delivery.
Current utilization does not show an urgent upgrade requirement for either component; the Ryzen Threadripper 1920X and GeForce RTX 4090 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 Threadripper 1920X paired with the GeForce RTX 4090 can run League of Legends smoothly up to 4k achieving around 170 FPS at Ultra quality. Your GPU is 1277% above the recommended specs, and your CPU is 261% above the recommended requirements.
This CPU + GPU combo costs approximately $1914 ($265 CPU (Rank #279 Value) + $1649 GPU (Rank #77 Value)). 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 9950X is a great upgrade option for around $649 (Rank #5 for value).
For League of Legends, upgrading the CPU would have the biggest impact on performance. The Ryzen Threadripper 1920X 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, 1440p low, 1440p medium, 4k low, 4k medium, 4k high, 4k ultra. GPU fully utilized at: 1080p medium, 1080p high, 1080p 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 Threadripper 1920X 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.
