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 765 FPS, suitable for 144Hz+ monitors. At 1440p, all settings exceed 506 FPS. At 4K, all settings exceed 306 FPS.
The GeForce RTX 4090 is 1277% above the recommended GPU (GeForce GTX 560) for League of Legends. The Ryzen Threadripper 3970X is 882% above the recommended CPU (Core i5-3330).
At lower resolutions (1440p (low/medium/high), all 4k settings), the Ryzen Threadripper 3970X sets the FPS ceiling. As graphical load increases at (1080p ultra), the GeForce RTX 4090 becomes the FPS-limiting side. The FPS ceiling is closely matched at 1080p (low/medium/high), 1440p ultra.
Approximated average price on current market:
Combo price: $6140. At 1080p Ultra, this combo delivers 765 FPS, equivalent to 0.12 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 ultra, the GeForce RTX 4090 sets the ceiling at about 717 FPS, while the Ryzen Threadripper 3970X has headroom up to 770 FPS. In this scenario, the GPU limits the CPU potential by 7% (FPS gap: 53 FPS). Overall distribution: GPU limits 3/12 cells, CPU limits 0/12, balanced 9/12. Confidence is low because both ceilings are very close in this cell.
The Ryzen Threadripper 3970X 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) | Balanced | Balanced | Balanced | GPU Limits CPU 7% |
| 4K (Ultra HD) | Balanced | Balanced | Balanced | GPU Limits CPU 7% |
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 Ryzen Threadripper 3970X paired with the GeForce RTX 4090 can run League of Legends smoothly up to 4k achieving around 306 FPS at Ultra quality. Your GPU is 1277% above the recommended specs, and your CPU is 882% above the recommended requirements.
This CPU + GPU combo costs approximately $6140 ($4491 CPU + $1649 GPU). Your Ryzen Threadripper 3970X 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 Ryzen Threadripper 9980X is a great upgrade option for around $4999 (Rank #868 for value).
Your Ryzen Threadripper 3970X 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, 1440p medium, 1440p high, 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 Ryzen Threadripper 3970X 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.
