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 447 FPS. At 4K, all settings exceed 281 FPS.
The RTX PRO 4000 Blackwell is 857% above the recommended GPU (GeForce GTX 560) for League of Legends. The Ryzen 7 7800X3D is 435% above the recommended CPU (Core i5-3330).
The RTX PRO 4000 Blackwell sets the FPS ceiling at all 1440p settings, all 4k settings, while the Ryzen 7 7800X3D still has additional frame-generation headroom. The FPS ceiling is closely matched at all 1080p settings.
Approximated average price on current market:
Combo price: $2084. At 1080p Ultra, this combo delivers 450 FPS, equivalent to 0.22 FPS per dollar.

This section is based on estimated CPU/GPU FPS ceilings, not utilization percentages.
At 4k ultra, the RTX PRO 4000 Blackwell sets the ceiling at about 227 FPS, while the Ryzen 7 7800X3D has headroom up to 310 FPS. In this scenario, the GPU limits the CPU potential by 27% (FPS gap: 83 FPS). Overall distribution: GPU limits 8/12 cells, CPU limits 0/12, balanced 4/12.
Your RTX PRO 4000 Blackwell is the limiting side in the heaviest mismatch. This means part of the Ryzen 7 7800X3D frame-generation potential remains unused in those settings.
| Resolution | Low | Medium | High | Ultra |
|---|---|---|---|---|
| 1080p (Full HD) | Balanced | Balanced | Balanced | Balanced |
| 1440p (2K QHD) | GPU Limits CPU 12% | GPU Limits CPU 16% | GPU Limits CPU 12% | GPU Limits CPU 23% |
| 4K (Ultra HD) | GPU Limits CPU 21% | GPU Limits CPU 19% | GPU Limits CPU 22% | GPU Limits CPU 27% |
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, not generic utilization heuristics.

Yes, the Ryzen 7 7800X3D paired with the RTX PRO 4000 Blackwell can run League of Legends smoothly up to 4k achieving around 281 FPS at Ultra quality. Your GPU is 857% above the recommended specs, and your CPU is 435% above the recommended requirements.
This CPU + GPU combo costs approximately $2084 ($384 CPU + $1700 GPU). Your RTX PRO 4000 Blackwell 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. For example, upgrading to the RTX PRO 6000 for around $8565 (Rank #91 for value) could deliver noticeably better performance.
Your RTX PRO 4000 Blackwell 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: 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 Ryzen 7 7800X3D and RTX PRO 4000 Blackwell 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.
