Doom

The AMD Ryzen 5 4600G paired with the AMD Radeon RX 580 presents a classic mid-range configuration when tested in Doom. The measured data shows a system that is clearly capable of smooth gameplay at standard resolutions, but which encounters a hard ceiling as pixel counts climb. The benchmark results indicate a balanced pairing at 1080p, where the combination of the 6-core processor and the Polaris-based graphics card delivers a strong experience, but the relationship between the two components shifts decisively at higher resolutions.

Resolution Scaling

The frame rate progression from 1920x1080 to 3840x2160 reveals a steep performance curve that points directly at the graphics card as the primary limiter at higher resolutions. At 1080p with Low settings, the configuration produces an average of 104.9 FPS. Moving to 2560x1440 at the same settings drops that figure to 64.3 FPS, a reduction of roughly 39%. Scaling further to 3840x2160 at Low settings yields an average of 36.2 FPS, which is only about 34% of the 1080p Low result. This dramatic falloff is characteristic of a GPU-bound scenario, where the RX 580’s compute resources are being saturated by the increasing pixel workload.

The pattern holds across all settings presets. At High settings, the average frame rate falls from 76.1 FPS at 1080p to 46.6 FPS at 1440p, and then to 25.6 FPS at 4K. The drop from 1440p to 4K is severe in every case, with the Ultra preset falling from 40.2 FPS to just 24.0 FPS. This data indicates that the Ryzen 5 4600G has ample headroom to feed the GPU at 1080p, but the RX 580’s 8 GB of GDDR5 memory and 256-bit bus cannot sustain playable rates when the resolution quadruples the pixel count from 1080p to 4K. The limiting component is unambiguously the graphics card, as the CPU’s workload does not increase proportionally with resolution.

CPU Role

The Ryzen 5 4600G contributes a solid foundation for Doom’s frame delivery. With 6 cores and 12 threads operating at a base clock of 3.70 GHz and a boost clock of 4.20 GHz, the processor provides sufficient single-thread performance for the game’s engine, which relies heavily on a few primary threads. The benchmark data for the CPU shows a Cinebench R23 multicore score of 13593 and a single-core score of 1919, indicating that the Zen 2 architecture handles both multi-threaded background tasks and the primary game thread with competence.

In the context of this game, the CPU’s role becomes more apparent at lower resolutions. At 1080p Low, the average of 104.9 FPS suggests that the processor is capable of driving the RX 580 to its limits without becoming a bottleneck. The 3DMark single-thread score of 726 and the PassMark single-thread score of 2653 reinforce that the per-core performance is adequate for a fast-paced FPS. The CPU’s 8 MB of shared L3 cache is modest by modern standards, but the measured frame rates indicate that it does not hinder performance in Doom at 1080p. As resolution increases, the CPU’s influence wanes, and the game becomes purely GPU-limited, as evidenced by the consistent frame rate collapses at 4K regardless of settings.

GPU Role

The AMD Radeon RX 580 is the decisive component in this pairing. Its specifications include a base clock of 1257 MHz and a boost clock of 1340 MHz, with 2304 shading units and 32 ROPs. The 8 GB of GDDR5 memory on a 256-bit bus provides 256.0 GB/s of bandwidth, which is sufficient for 1080p and 1440p textures but becomes strained at 4K. The GPU’s PassMark G3D score of 8813 places it in the 53rd percentile of all GPUs, and its nearest rivals in the database include the NVIDIA GeForce GTX 950 and the AMD Radeon Pro 455, with delta percentages of 0.1% and 1.1% respectively. This positions the RX 580 as a competent mid-range card for its era.

The measured FPS data shows that the GPU’s performance scales predictably with settings. At 1080p, the difference between Low and Ultra is 40.5 FPS (104.9 down to 64.4), demonstrating that the card has enough raw power to handle the game’s graphical features at lower resolutions. At 1440p, the gap narrows to 24.1 FPS (64.3 down to 40.2), and at 4K, the spread compresses to just 12.2 FPS (36.2 down to 24.0). This compression at higher resolutions is a classic sign of the GPU hitting its memory bandwidth ceiling, where increasing settings has diminishing returns because the card cannot push more pixels regardless of the workload.

How This Combo Ranks

In the overall database of tested combinations for Doom, this pairing of the Ryzen 5 4600G and RX 580 ranks 1544 out of 1681 tested combos. This places the configuration in the lower portion of the rankings, which is consistent with the component’s age and market position. The CPU’s percentile versus all CPUs is 75, meaning it outperforms three-quarters of tested processors, but the GPU’s percentile of 53 is more middling. The combination of a strong CPU with an average GPU results in a system that underperforms relative to the processor’s capabilities, particularly in a game like Doom where frame rates are heavily dependent on the graphics card.

The rank of 1544 out of 1681 suggests that most tested combos achieve higher average frame rates in this title. This is not surprising given that the GPU is an end-of-life product released in 2017, while the CPU was released in 2020. The mismatch in generations is evident in the benchmark scores, as the CPU’s average benchmark score of 17489 is close to its nearest rival, the AMD Ryzen 3 PRO 5355GE, which scores 17482 with a 0% delta. In contrast, the GPU’s average score of 13559 is nearly identical to the NVIDIA GeForce GTX 570, which scores 13564. The data shows that while the CPU holds its own against newer parts, the GPU is firmly rooted in an older performance tier.

Measured FPS Breakdown

The measured FPS data provides a complete picture of the configuration’s behavior across all settings and resolutions. At 1920x1080, the system achieves an average of 104.9 FPS on Low, 91.8 FPS on Medium, 76.1 FPS on High, and 64.4 FPS on Ultra. These numbers indicate that 1080p is the sweet spot for this combo, with even the highest preset remaining comfortably above the 60 FPS threshold. The scaling from Low to Ultra at 1080p is smooth, with each step up in settings costing roughly 12 to 15 FPS.

At 2560x1440, the averages drop to 64.3 FPS on Low, 58.3 FPS on Medium, 46.6 FPS on High, and 40.2 FPS on Ultra. The Low preset remains playable, but the High and Ultra presets fall below the ideal 60 FPS mark, suggesting that users should adjust settings carefully at this resolution. The 4K results are uniformly low: 36.2 FPS on Low, 32.7 FPS on Medium, 25.6 FPS on High, and 24.0 FPS on Ultra. None of these averages approach playable territory, confirming that 4K is not a viable option for this hardware combination in Doom.

Settings Recommendations

Based on the measured rows, the optimal experience for this configuration is at 1920x1080 with the High preset, which delivers an average of 76.1 FPS. This provides a significant margin above the 60 FPS target while still offering the visual fidelity of High settings. The Ultra preset at 1080p yields 64.4 FPS, which is also playable, but the 11.7 FPS difference between High and Ultra suggests diminishing returns for the extra graphical workload. For users prioritizing frame rate over visuals, the Medium preset at 1080p offers 91.8 FPS, which is nearly 20% faster than High and still looks respectable.

At 2560x1440, the Low preset is the only option that consistently exceeds 60 FPS, averaging 64.3 FPS. The Medium preset at 58.3 FPS is close to playable, but users with variable refresh rate monitors may notice occasional dips. The High and Ultra presets at 1440p are best avoided, as they drop below 47 FPS. For 4K, the data clearly shows that no settings preset produces a satisfactory result, with the highest average being 36.2 FPS on Low. The recommendation is to stick with 1080p for this combo, where the High preset offers the best balance of performance and image quality, or to drop to Medium if a higher frame rate is desired. The benchmark results indicate that this CPU-GPU pairing is well-matched for 1080p gaming, but the GPU becomes the bottleneck at higher resolutions.
