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 415 FPS, suitable for 144Hz+ monitors. At 1440p, all settings exceed 338 FPS. At 4K, all settings exceed 224 FPS.
The GeForce RTX 5090 is 1304% above the recommended GPU (GeForce GTX 560) for League of Legends. The EPYC 7H12 is 987% above the recommended CPU (Core i5-3330).
The EPYC 7H12 sets the FPS ceiling at 1080p (low/medium/high), all 1440p settings, all 4k settings, while the GeForce RTX 5090 still has headroom. The FPS ceiling is closely matched at 1080p ultra.
Approximated average price on current market:
Combo price: $4040. At 1080p Ultra, this combo delivers 415 FPS, equivalent to 0.1 FPS per dollar.

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 1080p low, the EPYC 7H12 sets the ceiling at about 641 FPS, while the GeForce RTX 5090 could reach 794 FPS. In this scenario, the CPU limits the GPU potential by 19% (FPS gap: 153 FPS). Overall distribution: CPU limits 9/12 cells, GPU limits 0/12, balanced 3/12.
Your EPYC 7H12 is the limiting side in the heaviest mismatch. This means part of the GeForce RTX 5090 rendering potential remains unused in those settings.
| Resolution | Low | Medium | High | Ultra |
|---|---|---|---|---|
| 1080p (Full HD) | CPU Limits GPU 19% | CPU Limits GPU 16% | CPU Limits GPU 13% | Balanced |
| 1440p (2K QHD) | CPU Limits GPU 19% | CPU Limits GPU 16% | CPU Limits GPU 13% | Balanced |
| 4K (Ultra HD) | CPU Limits GPU 15% | CPU Limits GPU 15% | CPU Limits GPU 13% | 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 and then monotonic-smoothed across heavier presets and resolutions, not generic utilization heuristics.

Yes, the EPYC 7H12 paired with the GeForce RTX 5090 can run League of Legends smoothly up to 4k achieving around 224 FPS at Ultra quality. Your GPU is 1304% above the recommended specs, and your CPU is 987% above the recommended requirements.
This CPU + GPU combo costs approximately $4040 ($1340 CPU + $2700 GPU). Your EPYC 7H12 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 9375F is a great upgrade option for around $5306 (Rank #5 for value).
Your EPYC 7H12 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, 1080p high, 1440p low, 1440p medium, 1440p high, 1440p ultra, 4k low, 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 7H12 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.
