Overpower

The pairing of AMD’s Ryzen 5 4600G with NVIDIA’s GeForce RTX 5090 presents a stark contrast in generational capability. The data from Overpower shows a system where the GPU is clearly the dominant force, yet the CPU’s limitations become apparent as resolution drops. This combination ranks 250th out of 1744 tested combos, placing it in the top tier of configurations, but the measured FPS reveals a nuanced story of scaling and bottlenecking that is critical for understanding its real-world performance.

Resolution Scaling

The measured FPS across resolutions demonstrates that this system is heavily GPU-bound at higher resolutions, with the CPU’s influence becoming more pronounced at 1080p. At 4K (3840x2160), the average FPS ranges from 110.4 at Ultra settings to 158.4 at Low. Moving down to 1440p (2560x1440), the frame rates increase modestly: 129.0 at Ultra and 168.0 at Low. The jump to 1080p (1920x1080) yields the highest raw numbers, with 133.8 at Ultra and 173.7 at Low, but the gains from 1440p are surprisingly small.

This pattern indicates that the RTX 5090 has enough headroom at 1440p that it is no longer the primary constraint; the Ryzen 5 4600G begins to cap the frame delivery. The delta between 1440p Low (168.0 FPS) and 1080p Low (173.7 FPS) is only 5.7 FPS, a mere 3.4% improvement. In contrast, the difference between 4K Low (158.4 FPS) and 1440p Low (168.0 FPS) is 9.6 FPS, a 6.1% gain. This compression of scaling at lower resolutions is the classic signature of a CPU limit, where the graphics card is waiting on the processor to feed it data. The 4600G’s 6 cores and 12 threads, based on the older Zen 2 architecture, simply cannot push the RTX 5090 to its full potential when the pixel workload is lighter.

CPU Role

The Ryzen 5 4600G is a 7 nm Zen 2 processor with 6 cores and 12 threads. Its base clock is 3.70 GHz, boosting to 4.20 GHz, and it features 8 MB of shared L3 cache. In the context of this game, these specifications yield a specific performance profile. The data shows that the CPU is a moderate performer, with a percentile ranking of 75.0 against all CPUs. Its average benchmark score is 17489.

When compared to its nearest rivals, the 4600G’s position is clear. It is virtually tied with the AMD Ryzen 3 PRO 5355GE (0.0% delta) and the Intel Core i5-12450H (0.1% delta). It trails the Intel Core i3-14100T by 0.8% and the Intel Core i3-13100F by 1.0%. These are all processors from a similar performance class, indicating that the 4600G is not a standout in computational power. Its single-threaded performance, as seen in benchmarks like 3dMark_single_thread (score of 726) and Cinebench R20 single-core (score of 805), is adequate but not exceptional. This modest CPU performance is why the game’s frame rates plateau at 1080p, as the processor’s capacity to issue draw calls and manage game logic becomes the limiting factor.

GPU Role

The NVIDIA GeForce RTX 5090 is the polar opposite of the CPU. It is a 5 nm Blackwell 2.0 architecture chip with 21,760 shading units, 680 TMUs, and 176 ROPs. Its memory subsystem is substantial, featuring 32 GB of GDDR7 memory on a 512-bit bus, delivering a bandwidth of 1.79 TB/s. The GPU also boasts 170 RT cores and 680 Tensor cores, and its boost clock is 2407 MHz. This hardware makes it a top-tier component, ranking in the 94th percentile against all GPUs.

The benchmark data highlights its dominance. In 3DMark Steel Nomad DX12, it scores 14411. Its Passmark G3D score is 39650, and its average benchmark score is 84306. The nearest rivals show it is essentially in a league of its own, with the closest competitor, the NVIDIA GeForce RTX 5090 D, being only 0.1% faster. The RTX 5090’s sheer power is evident in the 4K results, where it still manages to deliver over 110 FPS at Ultra settings in this game. The GPU’s performance is so high that, at 4K, it is doing the heavy lifting, and the difference between 110.4 FPS at Ultra and 158.4 FPS at Low demonstrates that the graphics card’s workload scales dramatically with settings. The 32 GB VRAM and massive bandwidth ensure that memory capacity is never a constraint, even at 4K Ultra with potential future texture packs.

How This Combo Ranks

The combination of these two disparate components results in a system that ranks 250th out of 1744 tested combos. This places it in the top 14.3% of all configurations tested, which is a strong position overall. However, this rank is almost entirely attributable to the GPU’s immense power. The data suggests that the CPU is holding the system back from an even higher placement.

If the RTX 5090 were paired with a more capable processor, the combo rank would likely be much higher, as the GPU would be allowed to stretch its legs. As it stands, the 4600G acts as a bottleneck, particularly in CPU-intensive scenarios. The rank of 250 indicates that there are 249 other combinations that perform better, and it is highly probable that many of those feature a stronger CPU. The system reflects the RTX 5090’s brute force, but the measured FPS data confirms that the processor is a limiting factor that prevents this combo from reaching the absolute top tier of performance.

Measured FPS Breakdown

The following table details the exact measured average FPS for each resolution and settings configuration.

| Resolution | Settings | Average FPS |

|:--------- |:------- | ----------: |

| 3840x2160 | High | 130.7 |

| 3840x2160 | Low | 158.4 |

| 3840x2160 | Medium | 135.4 |

| 3840x2160 | Ultra | 110.4 |

| 2560x1440 | High | 137.1 |

| 2560x1440 | Low | 168.0 |

| 2560x1440 | Medium | 142.9 |

| 2560x1440 | Ultra | 129.0 |

| 1920x1080 | High | 141.3 |

| 1920x1080 | Low | 173.7 |

| 1920x1080 | Medium | 146.7 |

| 1920x1080 | Ultra | 133.8 |

Analyzing the data, the performance deltas between settings are consistent. At every resolution, Low settings provide the highest average FPS, followed by High, then Medium, with Ultra being the most demanding. For instance, at 4K, the gap between Low (158.4 FPS) and Ultra (110.4 FPS) is 48.0 FPS, a 30.3% reduction in performance. This shows that the game is sensitive to the graphical load, and the RTX 5090 scales accordingly.

However, the most telling data is the cross-resolution scaling at the same settings. For High settings, the FPS goes from 130.7 at 4K to 137.1 at 1440p to 141.3 at 1080p. This is a total increase of only 10.6 FPS from 4K to 1080p. For Low settings, the increase is from 158.4 to 168.0 to 173.7, a total gain of 15.3 FPS. This limited scaling as resolution decreases is a clear indicator that the CPU is the primary bottleneck at 1080p. A system without a CPU bottleneck would show a much larger FPS jump when moving from 4K to 1080p, as the GPU’s workload would be significantly reduced. Here, the 4600G’s limitations cap the maximum achievable frame rate, meaning that the RTX 5090 is not being fully utilized at lower resolutions. The system delivers excellent playable frame rates across all tested configurations, but the data clearly shows that the processor is the weaker link in this pairing.
