Doom

The AMD Ryzen 5 4600G paired with the AMD Radeon RX 7600 delivers a robust 1080p experience in Doom, but the data reveals a clear shift in system bottlenecks as resolution climbs. At 1080p, the combination is firmly GPU-bound at higher settings, while the 4K results show the GPU struggling to maintain fluid frame rates, indicating that the RX 7600 is the primary limiting factor in this title.

Resolution Scaling

The measured frame rates demonstrate a steep performance curve as resolution increases, with the most dramatic drop occurring between 1440p and 4K. At the High preset, the average frame rate falls from 143.7 FPS at 1920x1080 to 93.7 FPS at 2560x1440, a reduction of 50 FPS. Scaling further to 3840x2160 yields 52.2 FPS, which is 91.5 FPS lower than the 1080p result. This pattern strongly suggests that the RX 7600’s rendering capabilities, rather than the CPU’s processing power, are the decisive factor at higher resolutions.

The scaling behavior across the Low preset is particularly telling. At 1080p Low, the system achieves 194.3 FPS, but this falls to 123.7 FPS at 1440p and 67.5 FPS at 4K. The percentage drop from 1440p to 4K (45.4%) is nearly identical to the drop seen on the High preset (44.3%), indicating that the resolution impact is consistent regardless of graphical load. This uniformity points to a fixed hardware limit—the GPU’s pixel throughput and memory bandwidth—rather than a dynamic bottleneck that shifts with settings.

When examining the Ultra preset, the scaling becomes even more pronounced. The system delivers 118.8 FPS at 1080p, 75.8 FPS at 1440p, and only 43.5 FPS at 4K. The gap between 1080p and 1440p is 43 FPS, while the gap between 1440p and 4K is 32.3 FPS. While the absolute drop is smaller at the top end, the relative performance at 4K Ultra (43.5 FPS) falls well below the 60 FPS threshold, confirming that this preset is not viable at the highest resolution.

The data indicates that the Ryzen 5 4600G, with its 6 cores and 12 threads, is not the constraint here. At 1080p Low, the system exceeds 190 FPS, which would require strong CPU throughput. The fact that frame rates scale so predictably with resolution suggests the CPU has headroom remaining even at the lowest settings, and the GPU becomes the sole bottleneck as pixel count increases.

GPU Role

The AMD Radeon RX 7600 features 8 GB of GDDR6 memory on a 128-bit bus, providing a memory bandwidth of 288.0 GB/s. This bandwidth is sufficient for 1080p and 1440p gaming in Doom, but the 4K results indicate it is a limiting factor. At 4K, the GPU’s base clock of 1720 MHz and boost clock of 2655 MHz are pushed to their limits, yet the average frame rates of 52.2 FPS (High) and 43.5 FPS (Ultra) show that the memory subsystem and shading units cannot keep pace with the increased pixel workload.

The GPU’s 2048 shading units and 64 ROPs are responsible for the raw fill rate, and the data suggests these are saturated at 4K. The pixel rate of 169.9 GPixel/s is the theoretical maximum, but realistic performance in Doom at 4K falls short of that figure due to the game’s rendering complexity. The texture rate of 339.8 GTexel/s, combined with the 128 TMUs, handles texture-heavy scenes adequately at lower resolutions but becomes a constraint at 4K Ultra.

Interestingly, the RX 7600’s average benchmark score of 20258 places it in the 63rd percentile of all GPUs, yet its nearest rival, the AMD Radeon RX 7600 XT, scores 20146 with a deltaPct of 0.6, meaning the RX 7600 actually outperforms its higher-tier sibling by a small margin in the aggregate benchmark. This suggests the RX 7600 is well-tuned for its class, and the Doom results reflect that efficiency. The GPU’s 8 GB VRAM capacity is not directly tested in the frame rate data, but the consistent performance degradation at 4K implies that memory capacity is not the issue; rather, it is the bandwidth and compute throughput that limit high-resolution performance.

How This Combo Ranks

The combination of the Ryzen 5 4600G and RX 7600 ranks 1124 out of 1681 tested combos in Doom, placing it in the lower third of all configurations. This ranking is somewhat surprising given the strong 1080p results, but it reflects the fact that many other combos feature more powerful CPUs or GPUs that excel at higher resolutions. The combo’s percentile position suggests that while it is capable of excellent frame rates at 1080p, it does not compete with top-tier builds in this specific game.

The CPU’s individual standing provides context for this ranking. The Ryzen 5 4600G scores 17489 on average, placing it in the 75th percentile of all CPUs. Its nearest rivals include the AMD Ryzen 3 PRO 5355GE (deltaPct 0) and the Intel Core i5-12450H (deltaPct 0.1), indicating that the 4600G is competitive with mid-range processors. The Intel Core i3-14100T and i3-13100F score slightly higher (17636 and 17665 respectively), with deltaPct values of -0.8 and -1, meaning the 4600G trails them by less than 1% in aggregate CPU benchmarks. This tight grouping shows that the CPU is not a weak link in the combo.

The GPU’s ranking is more modest, sitting at the 63rd percentile with an average score of 20258. Its nearest rival, the RX 7600 XT, is effectively matched (deltaPct 0.6), while the NVIDIA GeForce RTX 3070 Mobile and Intel Arc B570 score higher (20534 and 20556 respectively, with deltaPct of -1.3 and -1.5). This indicates that the RX 7600 is slightly below the performance of those alternatives in synthetic benchmarks, which may contribute to the combo’s overall 1124 rank. However, the Doom measurements show that the combo still delivers playable frame rates at 1440p on High, which is a positive outcome for this pairing.

Settings Recommendations

Based on the measured data, the optimal settings for this combo depend on the target resolution and frame rate preference. At 1920x1080, the High preset delivers 143.7 FPS, which is an excellent balance of visual quality and performance. The Medium preset offers 169.9 FPS, a 26.2 FPS improvement, but the visual difference between High and Medium in Doom is typically modest. The Ultra preset drops to 118.8 FPS, which is still above 60 FPS but represents a 24.9 FPS penalty over High. For most users, High at 1080p provides the best experience per the measured rows.

At 2560x1440, the High preset produces 93.7 FPS, which is smooth for fast-paced gameplay. The Medium preset reaches 111.4 FPS, offering a 17.7 FPS advantage, but the Low preset (123.7 FPS) provides diminishing returns in visual quality. The Ultra preset at 75.8 FPS is playable but may exhibit occasional dips in demanding scenes. The data suggests that High is the sweet spot at 1440p, delivering above 90 FPS while maintaining reasonable visual fidelity.

For 3840x2160, the results are less favorable. The High preset achieves 52.2 FPS, which is below the 60 FPS target for competitive play. The Medium preset (58.5 FPS) is close to playable but still falls short. The Low preset (67.5 FPS) is the only option that exceeds 60 FPS at 4K, but it requires sacrificing significant visual quality. The Ultra preset at 43.5 FPS is not recommended for serious gameplay. Users prioritizing 4K should consider the Low preset, while those who value visuals over frame rate may accept the High preset’s 52.2 FPS.

Measured FPS Breakdown

At 1920x1080, the system demonstrates its peak performance across all settings. The Low preset averages 194.3 FPS, the highest recorded value in the entire dataset. The Medium preset follows at 169.9 FPS, while the High preset reaches 143.7 FPS. The Ultra preset pulls 118.8 FPS, which is still well above the 60 FPS threshold. The spread from Low to Ultra is 75.5 FPS, showing that the RX 7600 has substantial headroom at this resolution even with the most demanding settings.

Moving to 2560x1440, the frame rates decrease noticeably but remain respectable. The Low preset achieves 123.7 FPS, a 70.6 FPS drop from the 1080p result. The Medium preset delivers 111.4 FPS, while High reaches 93.7 FPS. The Ultra preset falls to 75.8 FPS, which is still playable but represents a 43 FPS reduction from the 1080p Ultra figure. The performance gap between Low and Ultra at 1440p is 47.9 FPS, slightly narrower than at 1080p, indicating the GPU is starting to become more of a limiting factor.

At 3840x2160, the system’s limitations become apparent. The Low preset averages 67.5 FPS, which is the only setting to exceed 60 FPS at this resolution. The Medium preset follows at 58.5 FPS, while High drops to 52.2 FPS. The Ultra preset bottoms out at 43.5 FPS, which is 24 FPS below the 60 FPS target. The total spread from Low to Ultra at 4K is 24 FPS, significantly narrower than at lower resolutions, confirming that the GPU is heavily constrained. The data shows that this combo is best suited for 1080p and 1440p gaming, with 4K requiring substantial settings compromises to achieve acceptable frame rates.
