Red Dead Redemption 2

The AMD Ryzen 5 4600G paired with the Intel Arc B580 in Red Dead Redemption 2 presents a study in balanced scaling and clear performance tiers. The dataset shows a component pairing that is competent at 1080p, adequate at 1440p, and increasingly constrained as resolution climbs toward 4K. The measured frames per second across four presets at three resolutions provide a clear picture of where this combination excels and where it struggles.

Resolution Scaling

The frame rate trajectory from 1080p to 4K is decisive and reveals a GPU-bound system at higher resolutions. At 1080p with High settings, the combo delivers 54.4 FPS. Moving to 2560x1440 at the same preset drops the average to 40.6 FPS, a reduction of roughly 25%. Pushing to 3840x2160 High yields 28.8 FPS, which is a further 29% decline from the 1440p figure and only about 53% of the 1080p performance.

The Low preset tells a similar story but with higher absolute numbers. At 1920x1080 Low, the average is 89.9 FPS, which drops to 68.6 FPS at 1440p and then to 42.5 FPS at 4K. The scaling from 1080p to 4K on Low is a 47% loss, indicating that even at the lowest graphical load, the pixel throughput demand at 4K overwhelms the Arc B580's capabilities. This pattern is consistent with a GPU that has ample bandwidth—456.0 GB/s—but a raw compute ceiling that is hit hard by the 8.3 million pixel count of 4K.

The Ultra preset is the most punishing. At 1080p Ultra, the average is 42.5 FPS, identical to the 4K Low result. At 1440p Ultra, it falls to 32.8 FPS, and at 4K Ultra, it bottoms out at 20.9 FPS. The gap between 1080p and 4K on Ultra is a 51% reduction. The data suggests that the limiting component at 4K is unequivocally the GPU, as the frame rate collapses regardless of settings, while the CPU's role becomes more apparent at lower resolutions and higher frame rates.

CPU Role

The Ryzen 5 4600G is a 6-core, 12-thread processor based on the Zen 2 architecture, with a base clock of 3.70 GHz and a boost clock of 4.20 GHz. Its benchmark scores indicate a solid mid-range performer, with a Cinebench R23 multi-core score of 13593 and a single-core score of 1919. In the context of this game, the CPU is not the primary bottleneck at 4K, but its influence is visible in the scaling pattern.

At 1080p Low, where the GPU has less work, the frame rate reaches 89.9 FPS. This is a scenario where the CPU's 12 threads can keep up with the rendering demands. However, the 4600G's single-thread performance, while respectable, is not exceptional. The PassMark single-thread score of 2653 places it in a comparable tier to rivals like the Intel Core i3-13100F, which has a deltaPct of -1 in average benchmark score. The 4600G's multi-threaded capability is more pronounced, with a PassMark multi-thread score of 15992, which is useful for background tasks but not directly critical for this game's frame pacing.

The data indicates that when the GPU is stressed at 4K, the CPU has headroom to spare. At 4K Ultra, the frame rate is 20.9 FPS, which is a GPU-limited scenario. The CPU's 6 cores and 12 threads are sufficient to feed the Arc B580 at this resolution, as evidenced by the fact that lowering settings from Ultra to Low at 4K only improves performance from 20.9 to 42.5 FPS—a GPU-driven gain. The CPU's role is more nuanced at 1080p, where the difference between Low (89.9 FPS) and High (54.4 FPS) is 35.5 FPS, a larger delta than at 1440p, suggesting the CPU is beginning to influence the upper bound of performance on the Low preset.

Settings Recommendations

For the best experience per the measured rows, the Medium preset at 1920x1080 offers a strong balance. It delivers 67.9 FPS, which is above the 60 FPS threshold, and it is only 22 FPS lower than the Low preset's 89.9 FPS. The jump from Medium to High at 1080p costs 13.5 FPS (from 67.9 to 54.4), which is a significant penalty for likely modest visual gains. At 1080p, Medium is the pragmatic choice, providing a smooth frame rate while retaining more graphical fidelity than Low.

At 2560x1440, the situation is more constrained. The Medium preset yields 50.3 FPS, which is playable but not ideal for fast-paced action. The High preset at 1440p drops to 40.6 FPS, and Ultra falls to 32.8 FPS. For users prioritizing frame rate over visual flair, the Low preset at 1440p (68.6 FPS) is the only option that clears the 60 FPS bar. However, the data suggests that 1440p is the "sweet spot" for this combo on Medium, as the 50.3 FPS average is within a reasonable range for a narrative-driven game like Red Dead Redemption 2.

At 3840x2160, no preset achieves a consistently smooth frame rate. The best result is 42.5 FPS on Low, which is below the 60 FPS target. The Ultra preset at 4K is effectively unplayable at 20.9 FPS. For this resolution, the recommendation is to stick with Low or Medium (35.6 FPS) if the user accepts a sub-60 FPS experience, but the data clearly shows that this combo is not suited for 4K gaming in this title.

How This Combo Ranks

The combination ranks 1302 out of 1687 tested combos in Red Dead Redemption 2. This places it in the lower third of all combinations, indicating that while it is functional, it is far from a top-tier setup. The rank of 1302 out of 1687 suggests that a significant number of other CPU-GPU pairings outperform this one in this specific game. The Ryzen 5 4600G's percentile vs all CPUs is 75, meaning it outperforms 75% of CPUs in general benchmarks, but the Arc B580's percentile vs all GPUs is 66, which is lower. This discrepancy explains the combo's middling rank: the CPU is above average, but the GPU is merely average, and in a game like Red Dead Redemption 2, the GPU is the dominant factor at higher resolutions.

The combo's rank is not surprising given the measured data. At 1080p, it achieves acceptable frame rates, but at 1440p and 4K, it falls short of the performance levels seen in higher-ranked combinations. The rank of 1302 indicates that users seeking high-refresh-rate 1440p or 4K gaming would need to look at more powerful GPU combinations. For 1080p gaming, this combo is serviceable, but it does not stand out in the broader landscape of tested hardware.

GPU Role

The Intel Arc B580 is the dominant component in this pairing, and its characteristics define the system's performance envelope. It features 12 GB of GDDR6 memory on a 192-bit bus, providing a bandwidth of 456.0 GB/s. The base and boost clocks are both 2670 MHz, which is a high clock speed for a GPU, and it has 2560 shading units. Its FP32 performance is 13.67 TFLOPS, which is a moderate figure for a modern GPU.

The GPU's benchmarks show a mixed profile. Its PassMark G3D score is 15748, which places it in the 66th percentile of all GPUs. Its nearest rivals include the AMD Radeon 760M (deltaPct of 0.1), the NVIDIA P106-100 (deltaPct of 0.3), and the NVIDIA GeForce RTX 4060 (deltaPct of -0.7). The close margins to these rivals indicate that the Arc B580 is competitive with mid-range offerings, but it is not a high-end part.

In Red Dead Redemption 2, the GPU's role is to render the game's vast open world. The data shows that the Arc B580 handles 1080p well, with the Low preset hitting 89.9 FPS. However, the GPU's raw compute power is not sufficient for 4K, as evidenced by the 20.9 FPS at Ultra. The 12 GB of VRAM is likely not the limiting factor here, as the game at 4K Ultra would be more constrained by the GPU's shading units and memory bandwidth. The high clock speed of 2670 MHz helps at lower resolutions, but the pixel fill rate of 213.6 GPixel/s is the bottleneck at 4K. The GPU's performance in this game is consistent with its benchmark scores: it is a capable 1080p and entry-level 1440p card, but it is not designed for 4K ultra settings. The measured data confirms that the Arc B580 is the primary determinant of frame rates, with the CPU playing a supporting role.
