Doom

The AMD Ryzen 7 7800X3D paired with the AMD Radeon RX 7700 delivers a compelling 1080p and 1440p experience in Doom, with the data showing a clear shift in system bottleneck as resolution climbs. At 4K, the GPU takes over as the primary limiting factor, while at lower resolutions, the processor’s strong single-thread performance keeps frame rates exceptionally high. This analysis breaks down the measured FPS results, contextualizes the hardware’s standing against its nearest rivals, and provides practical settings guidance based strictly on the provided data.

Resolution Scaling

The measured FPS data reveals a predictable yet informative scaling pattern as resolution increases from 1920x1080 to 3840x2160. At High settings, the average frame rate drops from 178 FPS at 1080p to 115 FPS at 1440p, a reduction of 63 FPS, and then falls further to 62 FPS at 4K. This trajectory indicates that the system is heavily CPU-bound at 1080p, where the Ryzen 7 7800X3D’s capabilities are the primary driver, allowing the GPU to push exceptionally high frame counts. The move to 1440p still shows strong performance, but the gap between 1080p and 1440p (a 35% decrease in FPS) is larger than the gap between 1440p and 4K (a 46% decrease), suggesting the GPU begins to exert more influence at the higher resolution.

Looking at Low settings, the scaling is even more pronounced. At 1080p, the system achieves 241 FPS, which drops to 156 FPS at 1440p and 85 FPS at 4K. The 1080p to 1440p drop of 85 FPS is significant, highlighting that even with reduced graphical load, the GPU’s rendering capacity becomes a constraint as pixel count grows. The 4K result of 85 FPS, while still playable, represents a 65% reduction from the 1080p figure, underscoring that the RX 7700 is not designed to maintain ultra-high refresh rates at this resolution, even on lower presets.

The Medium preset offers a middle ground, with average FPS of 210 at 1080p, 136 at 1440p, and 74 at 4K. The minimum FPS values recorded for this preset (179 at 1080p, 116 at 1440p, and 63 at 4K) show that frame pacing remains consistent, with no severe dips that would suggest a stutter-prone experience. The Ultra preset, which is the most demanding, sees average FPS of 145 at 1080p, 94 at 1440p, and 51 at 4K. The 4K Ultra result is the only configuration that dips below the 60 FPS threshold, indicating that this preset and resolution combination is too demanding for the RX 7700 to maintain smooth gameplay.

The data implies that the limiting component shifts based on resolution. At 1080p, the CPU’s ability to feed frames is the ceiling, as evidenced by the high FPS across all settings, with even Ultra hitting 145 FPS. At 4K, the GPU’s fill rate and compute power become the bottleneck, as shown by the dramatic FPS drops across all presets. This behavior is typical for a mid-range GPU paired with a high-end CPU, where the processor’s headroom is only fully utilized at lower resolutions.

GPU Role

The AMD Radeon RX 7700, built on the RDNA 3.0 architecture with the Navi 32 chip, provides the rendering horsepower for this configuration. Its specifications include a base clock of 1900 MHz, a boost clock of 2459 MHz, and a game clock of 2041 MHz. The 16 GB of GDDR6 memory on a 256-bit bus offers a bandwidth of 624.1 GB/s, which is ample for Doom’s texture-heavy environments. The GPU’s 2560 shading units and 96 ROPs contribute to its pixel throughput of 236.1 GPixel/s, while the 160 TMUs deliver a texture rate of 393.4 GTexel/s.

In the context of the measured results, the GPU’s role becomes more critical as resolution increases. At 1080p with Low settings, the 241 FPS average suggests the GPU is not the limiting factor, as the CPU is likely keeping up with the relatively light rendering load. However, at 4K with Ultra settings, the 51 FPS average indicates the GPU is saturated. The difference between Low and Ultra at 4K (85 FPS vs. 51 FPS) is a 40% performance penalty, which is directly attributable to the increased shading and texture work required by the Ultra preset.

The GPU’s VRAM capacity of 16 GB is not a concern for this game, as Doom from 2016 is not particularly memory-hungry compared to modern titles. The 624.1 GB/s bandwidth ensures that texture streaming is unlikely to cause hitches, which is supported by the minimum FPS data for the Medium preset at 1440p (116 FPS) and 4K (63 FPS), showing no anomalous dips. The boost clock of 2459 MHz is moderately high, and the data suggests it is being utilized effectively to maintain the frame rates seen at 1080p and 1440p.

Comparatively, the RX 7700’s average benchmark score of 15852 places it in the 58th percentile among all GPUs. Its nearest rival, the AMD Radeon RX 9060, scores 16014, a 1% difference, while the NVIDIA GeForce RTX 3060 Ti scores 16129, a 1.7% difference. These close scores indicate that the RX 7700 is competitively positioned, and the Doom results reflect this mid-range standing, delivering high refresh rates at 1080p but struggling at 4K Ultra.

How This Combo Ranks

The percentileVsAllGpus of 58 for the RX 7700, combined with the CPU’s 83rd percentile ranking, suggests that the combo benefits significantly from the processor’s strength, which helps boost its position in games that are not purely GPU-bound.

The CPU’s nearest rivals include the AMD Ryzen 7 8700G and Intel Core i7-13650HX, both with an average benchmark score of 33089, representing a 0% deltaPct compared to the 7800X3D’s average of 33079. The AMD Ryzen 9 PRO 6950H scores 33201, a 0.4% difference. These negligible performance deltas indicate that the 7800X3D is firmly in the same performance class as these alternatives, meaning the combo’s ranking is primarily influenced by the GPU’s contribution. Since the GPU’s nearest rivals (RX 9060, RTX 3060 Ti) have similar average scores, the combo rank of 1724 is a fair representation of its overall gaming capability in Doom, sitting comfortably above the median but below the high-end configurations that feature flagship GPUs.

The data shows that this combo is better suited for 1080p and 1440p gaming, where the CPU’s high single-thread performance can be fully leveraged. At 4K, the combo’s ranking would likely be lower if isolated to that resolution, as the GPU becomes the limiting factor, but the overall rank of 1724 out of 3712 reflects a balanced system that excels in most scenarios.

Settings Recommendations

Based on the measured FPS data, the optimal settings for this combo depend on the target resolution and refresh rate. At 1920x1080, the Ultra preset is viable for 144 Hz displays, as the average FPS of 145 is above the 144 Hz threshold, though it does not reach the 240 Hz range. For players with 240 Hz monitors, the Low preset at 241 FPS or the Medium preset at 210 FPS are better choices, with Medium offering a substantial visual upgrade over Low while still maintaining high frame rates. The High preset at 178 FPS is a balanced option for 165 Hz displays, providing a good mix of visual fidelity and performance.

At 2560x1440, the High preset delivers 115 FPS, which is suitable for 120 Hz displays, while the Medium preset at 136 FPS is better for 144 Hz panels, offering a 21 FPS improvement over High. The Ultra preset at 94 FPS is still playable for 90 Hz or 100 Hz displays, but the visual gains over High may not justify the 21 FPS reduction. The Low preset at 156 FPS is the choice for 144 Hz or 165 Hz monitors, but it sacrifices significant visual quality, so Medium is recommended for most users as the best experience-to-performance ratio.

At 3840x2160, the Medium preset at 74 FPS is the highest average that stays above 60 FPS, making it the recommended choice for 4K60 displays. The Low preset at 85 FPS offers a smoother experience but with reduced detail, while the High preset at 62 FPS is marginally above 60 FPS but may have occasional dips. The Ultra preset at 51 FPS is not recommended for 60 Hz displays, as it fails to maintain a consistent 60 FPS. Overall, the Medium preset at 4K provides the best balance, while at 1080p and 1440p, users can comfortably use High or Ultra depending on their refresh rate preferences.
