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

At 4k high, the EPYC 7402P sets the ceiling at about 248 FPS, while the GeForce RTX 4090 could reach 301 FPS. In this scenario, the CPU limits the GPU potential by 18% (FPS gap: 53 FPS). Overall distribution: CPU limits 9/12 cells, GPU limits 0/12, balanced 3/12.
Your EPYC 7402P 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 7% | Balanced | CPU Limits GPU 13% | CPU Limits GPU 14% |
| 1440p (2K QHD) | CPU Limits GPU 11% | CPU Limits GPU 7% | CPU Limits GPU 13% | Balanced |
| 4K (Ultra HD) | Balanced | CPU Limits GPU 6% | CPU Limits GPU 18% | CPU Limits GPU 16% |
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.

The EPYC 7402P + GeForce RTX 4090 pairing runs this title with CPU utilization between 37% and 84% and GPU utilization between 25% and 66%. EPYC 7402P stays in a controlled operating range, while GeForce RTX 4090 is utilized efficiently without persistent saturation. As resolution scales, average GPU load rises from 30% at 1080p to 61% at 4K, while CPU averages move from 65% to 63%.
The utilization pattern is relatively balanced. The GeForce RTX 4090 reaches 64% average at its highest-load preset, while the EPYC 7402P peaks at 68% average, with no single component consistently acting as a hard bottleneck.
At 1080p, averages sit around CPU 65% and GPU 30%. At 1440p, that shifts to CPU 65% and GPU 38%, and at 4K it reaches CPU 63% and GPU 61%. 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 63% (43-83%) and GPU 64% (61-66%), which keeps GeForce RTX 4090 well utilized without constant max-out behavior while EPYC 7402P remains stable for consistent frame delivery.
Current utilization does not show an urgent upgrade requirement for either component; the EPYC 7402P and GeForce RTX 4090 remain reasonably matched for this title.

Yes, the EPYC 7402P paired with the GeForce RTX 4090 can run League of Legends smoothly up to 4k achieving around 194 FPS at Ultra quality. Your GPU is 1277% above the recommended specs, and your CPU is 583% above the recommended requirements.
This CPU + GPU combo costs approximately $2739 ($1090 CPU (Rank #281 Value) + $1649 GPU (Rank #77 Value)). Your EPYC 7402P 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 processor with a significantly better value rating. For example, the EPYC 4585PX is a great upgrade option for around $699 (Rank #66 for value) while costing less than your current CPU.
Your EPYC 7402P 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 high, 1080p ultra, 1440p low, 1440p medium, 1440p high, 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 EPYC 7402P 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.
