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 450 FPS, suitable for 144Hz+ monitors. At 1440p, all settings exceed 367 FPS. At 4K, all settings exceed 213 FPS.
The GeForce RTX 4090 is 1277% above the recommended GPU (GeForce GTX 560) for League of Legends. The EPYC 7313P is 540% above the recommended CPU (Core i5-3330).
At lower resolutions (1440p low, all 4k settings), the EPYC 7313P determines the performance ceiling. As graphical load increases at (1080p ultra), the GeForce RTX 4090 takes over as the primary performance factor. The system is well balanced at 1080p (low/medium/high), 1440p (medium/high/ultra).
Approximated average price on current market:
Combo price: $2473. At 1080p Ultra, this combo delivers 450 FPS, equivalent to 0.18 FPS per dollar.

At 1440p low, the EPYC 7313P sets the ceiling at about 573 FPS, while the GeForce RTX 4090 could reach 653 FPS. In this scenario, the CPU limits the GPU potential by 12% (FPS gap: 80 FPS). Overall distribution: CPU limits 6/12 cells, GPU limits 2/12, balanced 4/12.
The EPYC 7313P 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) | Balanced | Balanced | Balanced | GPU Limits CPU 7% |
| 1440p (2K QHD) | CPU Limits GPU 12% | CPU Limits GPU 6% | Balanced | GPU Limits CPU 6% |
| 4K (Ultra HD) | CPU Limits GPU 8% | CPU Limits GPU 11% | CPU Limits GPU 7% | CPU Limits GPU 9% |
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 7313P + GeForce RTX 4090 pairing runs this title with CPU utilization between 20% and 36% and GPU utilization between 25% and 67%. EPYC 7313P 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%.
The utilization pattern is relatively balanced. The GeForce RTX 4090 reaches 64% average at its highest-load preset, while the EPYC 7313P peaks at 31% average, with no single component consistently acting as a hard bottleneck.
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.
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 7313P remains stable for consistent frame delivery.
Current utilization does not show an urgent upgrade requirement for either component; the EPYC 7313P and GeForce RTX 4090 remain reasonably matched for this title.

Yes, the EPYC 7313P paired with the GeForce RTX 4090 can run League of Legends smoothly up to 4k achieving around 213 FPS at Ultra quality. Your GPU is 1277% above the recommended specs, and your CPU is 540% above the recommended requirements.
This CPU + GPU combo costs approximately $2473 ($824 CPU (Rank #239 Value) + $1649 GPU (Rank #77 Value)). Your EPYC 7313P 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 Xeon Platinum 8571N is a great upgrade option for around $599 (Rank #60 for value) while costing less than your current CPU.
Your EPYC 7313P 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: 1440p low, 4k low, 4k medium, 4k high, 4k ultra. GPU fully utilized at: 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 EPYC 7313P 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.
