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.
Actual FPS may vary based on RAM speed, background processes, and other system factors
Performance Report
At 1080p, all quality settings exceed 623 FPS, suitable for 144Hz+ monitors. At 1440p, all settings exceed 467 FPS. At 4K, all settings exceed 357 FPS.
The GeForce RTX 4090 is 1277% above the recommended GPU (GeForce GTX 560) for League of Legends. The Ryzen 7 8845HS is 344% above the recommended CPU (Core i5-3330).
At lower resolutions (1080p low), the Ryzen 7 8845HS sets the FPS ceiling. As graphical load increases at (1080p (high/ultra), 1440p (medium/high/ultra), 4k (medium/high/ultra)), the GeForce RTX 4090 becomes the FPS-limiting side. The FPS ceiling is closely matched at 1080p medium, 1440p low, 4k low.
This chart answers a simple question: which upgrade is more likely to increase FPS first? In this case, the answer is the GPU.
The largest gap appears at 1080p Ultra, where the GeForce RTX 4090 reaches about 560 FPS, while the Ryzen 7 8845HS still has headroom up to roughly 623 FPS.
That means the GeForce RTX 4090 is hitting its performance ceiling first, leaving a 10% gap versus the Ryzen 7 8845HS's available headroom in the most unbalanced scenario. Across all tested settings, this pairing is GPU-limited in 8 out of 12 cases, with 1 CPU-limited and 3 balanced results.
Overall, this is a GPU-limited combination in this game.
The GeForce RTX 4090 is usually the limiting part in this game, so upgrading the GPU is more likely to deliver a larger FPS gain than upgrading the CPU.
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.
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 8845HS with GeForce RTX 5090, our current GPU anchor. To estimate the GPU ceiling, we pair the GeForce RTX 4090 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.

Yes, the Ryzen 7 8845HS paired with the GeForce RTX 4090 can run League of Legends smoothly up to 4k achieving around 357 FPS at Ultra quality. Your GPU is 1277% above the recommended specs, and your CPU is 344% above the recommended requirements.
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.
Your GeForce RTX 4090 is already a top-tier graphics card. In the Performance Limiter Analysis, it is still the side that most often reaches its FPS ceiling first, but there is no meaningful upgrade path that would drastically improve your League of Legends performance right now. The main bottleneck appears on the GPU side. The largest gap shows up at 1080p Ultra, where the GPU reaches about 560 FPS while the CPU still has headroom up to roughly 623 FPS. Across all tested settings, the distribution is 8/12 GPU-limited, 1/12 CPU-limited, and 3/12 balanced.
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 8845HS 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.
