League of Legends FPS on Ryzen 7 9800X3D + Radeon HD 6990M Crossfire

League of Legends FPS Performance Results

League of Legends

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.

📈Analysis

Which Component Limits FPS Most?

This chart answers a simple question: which upgrade is more likely to increase FPS first? In this case, the answer is clearly the GPU.

The largest gap appears at 4K Ultra, where the Radeon HD 6990M Crossfire reaches about 39 FPS, while the Ryzen 7 9800X3D still has headroom up to roughly 316 FPS.

That means the Radeon HD 6990M Crossfire is hitting its performance ceiling first, leaving a 88% gap versus the Ryzen 7 9800X3D's available headroom in the most unbalanced scenario. Across all tested settings, this pairing is GPU-limited in 12 out of 12 cases, with 0 CPU-limited and 0 balanced results.

Overall, this is a clearly GPU-bound combination in this game.

Verdict

Upgrade Recommendations

GPU-Limited

The Radeon HD 6990M Crossfire is consistently the limiting part in this game, so upgrading the GPU is more likely to deliver a larger FPS gain than upgrading the CPU.

Detailed BreakdownShows which upgrade is more likely to unlock more FPS in each tested setting

This chart shows which upgrade is more likely to unlock more FPS in each tested setting. The lower line represents the part that reaches its limit first. When the CPU and GPU lines stay close together, the system is more balanced. When the gap widens, one component is more clearly holding the other back. Hover any setting to inspect it.

The lower line is the current limiter. The closer the two lines are, the more balanced the CPU and GPU are for this game.

🧠Methodology

Each line represents an estimated FPS ceiling for one component, rather than live usage alone.

To estimate the CPU ceiling, we pair the Ryzen 7 9800X3D with GeForce RTX 5090, our current GPU anchor. To estimate the GPU ceiling, we pair the Radeon HD 6990M Crossfire with Ryzen 9 9950X3D, our current CPU anchor.

The lower line indicates the current limiter, since that component reaches its FPS ceiling first. In most scenarios, that is also the part most likely to deliver the bigger performance uplift if upgraded first.

The percentage shown represents the gap between the two ceilings. In practical terms, it shows how much of the stronger component's potential is left unused because the weaker one becomes the bottleneck first.

2Is there a more cost-effective setup to run League of Legends?

This CPU + GPU combo costs approximately $615.38 ($465.38 CPU + $150 GPU). Since the GPU is the main limiting factor, investing in a stronger GPU will improve your framerates and overall value. For example, upgrading to the Radeon RX 580 (móvel) for around $229 (Rank #323 for value) could deliver noticeably better performance.

3Which component should I upgrade first to improve League of Legends performance?

For League of Legends, upgrading the GPU would usually give you the most noticeable improvement. In the Performance Limiter Analysis, the Radeon HD 6990M Crossfire is the side that most often caps the frame rate, while the Ryzen 7 9800X3D still has additional headroom in the tested presets. The main bottleneck appears on the GPU side. The largest gap shows up at 4K Ultra, where the GPU reaches about 39 FPS while the CPU still has headroom up to roughly 316 FPS. Across all tested settings, the distribution is 12/12 GPU-limited, 0/12 CPU-limited, and 0/12 balanced.

4Does this setup support Frame Generation for League of Legends?

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.

5What are the minimum and recommended specs for League of Legends?

League of Legends requires at minimum a Core i3-530 (CPU) and GeForce 9600 GT (GPU) with 2 GB RAM and 16 GB storage.
