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, frame rates range from 45 to 89 FPS depending on quality settings. At 1440p, frame rates range from 33 to 67 FPS. At 4K, frame rates range from 22 to 45 FPS.
The GeForce GTX 670MX is 29% below recommended, but 256% above minimum for League of Legends. The Ryzen 7 7800X3D is 435% above the recommended CPU (Core i5-3330).
The GeForce GTX 670MX determines the performance ceiling at all 1080p settings, all 1440p settings, all 4k settings, executing at maximum capacity.
At 1440p ultra, the GeForce GTX 670MX sets the ceiling at about 33 FPS, while the Ryzen 7 7800X3D has headroom up to 450 FPS. In this scenario, the GPU limits the CPU potential by 93% (FPS gap: 417 FPS). Overall distribution: GPU limits 12/12 cells, CPU limits 0/12, balanced 0/12.
Your GeForce GTX 670MX 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) | GPU Limits CPU 87% | GPU Limits CPU 88% | GPU Limits CPU 88% | GPU Limits CPU 90% |
| 1440p (2K QHD) | GPU Limits CPU 90% | GPU Limits CPU 91% | GPU Limits CPU 91% | GPU Limits CPU 93% |
| 4K (Ultra HD) | GPU Limits CPU 92% | GPU Limits CPU 92% | GPU Limits CPU 92% | GPU Limits CPU 93% |
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 Ryzen 7 7800X3D + GeForce GTX 670MX pairing runs this title with CPU utilization between 4% and 19% and GPU utilization between 76% and 100%. Ryzen 7 7800X3D keeps significant headroom across presets, while GeForce GTX 670MX becomes the primary limiter at high visual load. As resolution scales, average GPU load rises from 95% at 1080p to 93% at 4K, while CPU averages move from 12% to 10%.
This profile is GPU-bound. At 1440p (2K QHD) Ultra, the GeForce GTX 670MX averages 99% usage (98-100%), while the Ryzen 7 7800X3D stays at 12% (5-19%), indicating the graphics pipeline is the limiting stage.
At 1080p, averages sit around CPU 12% and GPU 95%. At 1440p, that shifts to CPU 12% and GPU 96%, and at 4K it reaches CPU 10% and GPU 93%. This shows that workload scaling is limited, which can indicate engine-side constraints.
1080p (Full HD) Low is the most balanced preset based on this dataset. It runs around CPU 10% (4-15%) and GPU 89% (80-98%), which keeps GeForce GTX 670MX well utilized without constant max-out behavior while Ryzen 7 7800X3D remains stable for consistent frame delivery.
Upgrade priority should be the GPU. The GeForce GTX 670MX reaches 99% average load at 1440p (2K QHD) Ultra while the Ryzen 7 7800X3D still has headroom, so a faster graphics card would deliver the largest uplift.

The Ryzen 7 7800X3D and GeForce GTX 670MX will struggle to run League of Legends at smooth framerates. At 1080p Ultra, you can expect around 45 FPS which is classified as "playable". Consider lowering settings or upgrading your hardware.
Price data is not currently available for this combination. In general, look for setups where the CPU and GPU are balanced — this ensures you're not overspending on one component that the other can't keep up with.
For League of Legends, upgrading the GPU would give you the most noticeable improvement. The GeForce GTX 670MX is the limiting factor here, while the Ryzen 7 7800X3D still has spare capacity. A more powerful GPU would unlock higher FPS, especially at higher resolutions and quality presets. GPU-limited at: 1080p low, 1080p medium, 1080p high, 1080p ultra, 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 setup meets the minimum requirements but falls short of the recommended specs. You may need to lower some settings for smooth performance.
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.
