League of LegendsFPS onEPYC 9124&GeForce RTX 4090

League of Legends

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.

Percentages show how much potential FPS of the stronger component is lost because the other component has a lower FPS ceiling.
🧠Methodology

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.

The displayed percentages are derived from FPS ceilings, not generic utilization heuristics.

Performance Summary

The EPYC 9124 + GeForce RTX 4090 pairing runs this title with CPU utilization between 20% and 36% and GPU utilization between 25% and 67%. EPYC 9124 keeps significant headroom across presets, while GeForce RTX 4090 is utilized efficiently without persistent saturation. As resolution scales, average GPU load rises from 28% at 1080p to 61% at 4K, while CPU averages move from 28% to 27%.

Bottleneck Analysis

The utilization pattern is relatively balanced. The GeForce RTX 4090 reaches 64% average at its highest-load preset, while the EPYC 9124 peaks at 31% average, with no single component consistently acting as a hard bottleneck.

Resolution Scaling

At 1080p, averages sit around CPU 28% and GPU 28%. At 1440p, that shifts to CPU 28% and GPU 36%, and at 4K it reaches CPU 27% and GPU 61%. This shows that GPU demand scales sharply with resolution while CPU load remains comparatively stable.

Optimal Settings Recommendation

4K (Ultra HD) Ultra is the most balanced preset based on this dataset. It runs around CPU 27% (24-30%) and GPU 64% (61-67%), which keeps GeForce RTX 4090 well utilized without constant max-out behavior while EPYC 9124 remains stable for consistent frame delivery.

Upgrade Insight

Current utilization does not show an urgent upgrade requirement for either component; the EPYC 9124 and GeForce RTX 4090 remain reasonably matched for this title.

Understanding Hardware Utilization & Bottlenecks: These percentages represent how much of your component's maximum processing power is actively being used during gameplay. This is the key to identifying performance bottlenecks in any system.

  • The Ideal Scenario (GPU Bottleneck): You typically want to see High GPU Utilization (90%+) and moderate CPU usage. This indicates your system is successfully pushing out graphics as fast as it can, without being held back by the CPU.
  • CPU Bottleneck: If you see High CPU Utilization (85%+) paired with lower GPU utilization, the CPU is struggling to compute game logic and prepare frames fast enough. The GPU sits waiting, often resulting in stuttering, inconsistent frame times, and lower overall FPS.
  • Engine Limits or Capped FPS: If both CPU and GPU utilization are relatively low, it means the hardware is waiting on something else. This could be a game engine limitation, poorly optimized code, or an artificial framerate cap like VSync holding performance back.

Frequently Asked Questions

1Can the EPYC 9124 and GeForce RTX 4090 run League of Legends well?

Yes, the EPYC 9124 paired with the GeForce RTX 4090 can run League of Legends smoothly up to 4k achieving around 209 FPS at Ultra quality. Your GPU is 1277% above the recommended specs, and your CPU is 581% above the recommended requirements.

2Is there a more cost-effective setup to run League of Legends?

This CPU + GPU combo costs approximately $2732 ($1083 CPU (Rank #258 Value) + $1649 GPU (Rank #77 Value)). Your GeForce RTX 4090 provides phenomenal top-tier performance but at a premium enthusiast price. Since you are essentially at the ceiling of current hardware capabilities, there are no meaningful performance upgrades available. However, if you wanted a more cost-effective build that still delivers a great experience, you could theoretically step down to a high-end card with a significantly better value rating.

3Which component should I upgrade first to improve League of Legends performance?

Your GeForce RTX 4090 is already a top-tier graphics card. While it's technically the limiting factor here (which means you are fully utilizing your GPU's visual horsepower exactly as intended), there is no meaningful upgrade path that would drastically improve your League of Legends performance right now. GPU fully utilized at: 1080p medium, 1080p high, 1080p ultra. CPU fully utilized at: 1440p low, 1440p medium, 4k medium.

4Does this setup support Frame Generation for League of Legends?

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.

5What are the minimum and recommended specs for League of Legends?

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 EPYC 9124 and GeForce RTX 4090 both exceed the recommended specs, so you're well-positioned for a great experience.

6How accurate are these League of Legends FPS estimates for the EPYC 9124 and GeForce RTX 4090?

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.
