Doom

The AMD Ryzen 5 5600G paired with the AMD Radeon RX 6700 XT delivers a robust 1080p and 1440p experience in Doom, though 4K Ultra settings push the combination to its limits. The measured frame rates reveal a system where the GPU becomes the dominant performance constraint as resolution increases, with the CPU’s six Zen 3 cores providing ample headroom at lower resolutions. This analysis breaks down the scaling behavior, the GPU’s role, and the optimal settings for this specific hardware pairing.

Resolution Scaling

The frame rate progression from 1920x1080 to 3840x2160 demonstrates classic GPU-bound scaling in Doom. At 1080p High, the combo produces 170.5 FPS, which drops to 108.9 FPS at 1440p, a reduction of approximately 36%. Moving to 4K High yields 62 FPS, a further 43% decline from 1440p. This steep drop-off—nearly halving performance with each resolution step—indicates the RX 6700 XT is the limiting factor at higher pixel counts, while the Ryzen 5 5600G’s processing power remains underutilized.

The scaling pattern holds across all settings presets. At Low settings, 1080p delivers 229.3 FPS, 1440p drops to 152 FPS (a 34% decrease), and 4K falls to 79.1 FPS (a 48% decrease from 1440p). The consistent ~35-48% reduction per resolution tier suggests the GPU’s fill rate and memory bandwidth are being saturated, rather than any CPU bottleneck. At 1080p, the delta between Low and Ultra is 87.9 FPS (229.3 vs 141.4), whereas at 4K the same delta is only 32.5 FPS (79.1 vs 46.6). This narrowing gap at higher resolutions confirms that the GPU is the primary constraint, as the additional load from Ultra settings cannot be compensated by the CPU’s headroom.

Interestingly, the 1440p results show a different dynamic. The gap between Low (152 FPS) and Ultra (92 FPS) is 60 FPS, which is proportionally larger than at 1080p but smaller than at 4K. This suggests 1440p is the transition zone where the GPU starts to become fully utilized, but the CPU still contributes meaningfully to frame delivery. The 4K Ultra result of 46.6 FPS—the lowest measured score—represents a scenario where the RX 6700 XT is completely saturated, with its 12 GB of VRAM and 384.0 GB/s bandwidth being the decisive factors.

GPU Role

The Radeon RX 6700 XT’s specifications directly explain the observed performance envelope. With a base clock of 2321 MHz and a boost clock of 2581 MHz, the GPU sustains high throughput, but its 192-bit memory bus and 12 GB of GDDR6 memory determine the upper limits at 4K. The 384.0 GB/s memory bandwidth is sufficient for 1080p and 1440p, where the data shows frame rates well above 90 FPS even at Ultra settings. However, at 4K Ultra, the 46.6 FPS result indicates the memory subsystem and the 64 ROPs are overwhelmed.

The GPU’s 2560 shading units and 160 TMUs provide ample compute for Doom’s id Tech engine, which scales well with raw shader throughput. The measured 1080p High score of 170.5 FPS demonstrates that the GPU is not the limiting factor at this resolution, as the CPU’s single-thread performance (Cinebench R23 single-core score of 2365) can feed frames faster than the GPU can render them. The 4K Low result of 79.1 FPS versus 4K High of 62 FPS shows that even at lower settings, the GPU’s pixel fill rate (165.2 GPixel/s) becomes the bottleneck.

The RX 6700 XT’s position relative to its nearest rivals further contextualizes its role. The data shows it scores 0.7% higher than the AMD Radeon RX 6800 in average benchmarks, yet 1% lower than the AMD Radeon RX 480 and 1.3% lower than the NVIDIA RTX A5000. This places it in a competitive mid-range tier, which aligns with the measured results: strong at mainstream resolutions, but not a 4K powerhouse. The GPU’s 77th percentile ranking among all GPUs corroborates this, indicating it outperforms the majority of cards but lacks the top-tier bandwidth needed for consistent 4K Ultra play.

How This Combo Ranks

The AMD Ryzen 5 5600G + AMD Radeon RX 6700 XT combination ranks 936th out of 1681 tested combos in Doom, placing it in the 56th percentile of all configurations. This mid-pack ranking reflects a balanced pairing where neither component drastically outperforms the other, but the overall system is not optimized for maximum frame rates. The CPU’s own percentile ranking of 78th among all CPUs—with an average benchmark score of 19983—indicates it is a strong processor, sitting just 0.2% above the Intel Core i7-11600H and 0.3% above the AMD Ryzen Threadripper PRO 5995WX in aggregate scores. However, its gaming performance is moderated by the GPU’s 77th percentile ranking.

The combination’s rank suggests that while each component is individually capable, the pairing does not create a synergistic boost. In Doom, which is generally more GPU-bound, the Ryzen 5 5600G’s 6 cores and 12 threads provide sufficient processing for the game’s engine, but the RX 6700 XT’s mid-range positioning caps the system’s ceiling. The 936th rank out of 1681 combos means roughly 44% of tested configurations outperform it, which is consistent with the GPU being a mid-tier part rather than a high-end one. The CPU’s nearest rivals—which include server-class chips like the AMD EPYC 7713P—show that the 5600G competes well in synthetic benchmarks, but this does not translate to a top-tier gaming rank due to the GPU constraint.

Measured FPS Breakdown

At 1920x1080, the combo delivers excellent performance across all presets. Low settings produce 229.3 FPS, Medium yields 198.8 FPS, High reaches 170.5 FPS, and Ultra still manages 141.4 FPS. These numbers indicate a fully playable experience at any setting, with the gap between Low and Ultra (87.9 FPS) showing that the GPU has headroom to spare. The 1080p results are uniformly above 140 FPS, making this resolution ideal for high-refresh-rate monitors, as the data shows no setting drops below the 144 Hz threshold.

Moving to 2560x1440, the frame rates remain strong but show the GPU starting to work harder. Low hits 152 FPS, Medium achieves 132.3 FPS, High delivers 108.9 FPS, and Ultra dips to 92 FPS. The 1440p results are still above 90 FPS at every preset, meaning the combo can handle this resolution comfortably for competitive play. The 60 FPS delta between Low and Ultra at this resolution is proportionally similar to 1080p, indicating consistent scaling without sudden bottlenecks.

At 3840x2160, the performance drops significantly. Low produces 79.1 FPS, Medium yields 68.2 FPS, High reaches 62 FPS, and Ultra falls to 46.6 FPS. The 4K results reveal that only Low and Medium settings maintain playable frame rates above 60 FPS, while High and Ultra fall below that threshold. The 32.5 FPS spread between Low and Ultra at 4K is the smallest of all resolutions, confirming that the GPU is fully saturated and additional settings changes have diminishing returns.

Settings Recommendations

For 1920x1080, the data supports using Ultra settings as the default choice, as the 141.4 FPS result provides a smooth experience without sacrificing visual quality. Even the most demanding preset leaves substantial headroom, so there is no reason to reduce settings at this resolution. Players seeking maximum frame rates for competitive play can opt for Low at 229.3 FPS, but the Ultra preset remains the best balance of fidelity and performance.

At 2560x1440, High settings at 108.9 FPS offer the best experience, delivering smooth gameplay while maintaining visual detail. Ultra at 92 FPS is also playable, but the 16.9 FPS difference between High and Ultra may not justify the graphical upgrade for some users. Medium at 132.3 FPS is ideal for those prioritizing frame rate stability, but the data shows High provides a better balance, staying above the 100 FPS mark.

For 3840x2160, the recommendation is Medium settings at 68.2 FPS, as this is the highest preset that consistently exceeds 60 FPS. Low at 79.1 FPS offers additional headroom but sacrifices visual quality, while High at 62 FPS is borderline and Ultra at 46.6 FPS fails to meet the standard 60 FPS target. The measured data suggests that 4K gaming with this combo requires accepting Medium settings to achieve fluid motion, with Low being a viable alternative for higher frame rates.
