Doom

The AMD Ryzen 7 9800X3D paired with the AMD Radeon RX 7900 XT delivers exceptional frame rates in Doom, positioning this combo as a top-tier performer for the 2016 FPS title. The data shows a system that is heavily GPU-limited at 4K, but capable of pushing well beyond 200 FPS at 1080p, making it a versatile option for both high-refresh-rate esports and cinematic single-player experiences.

Resolution Scaling

The measured FPS data reveals a clear pattern of performance scaling as resolution increases, with the most significant drops occurring at the highest settings. Moving from 1920x1080 to 2560x1440 at Ultra settings, the average frame rate falls from 200.7 FPS to 131.2 FPS, a reduction that highlights the growing pressure on the GPU. The transition from 2560x1440 to 3840x2160 at the same preset is even more punishing, with the average dropping to 73.2 FPS. This 58 FPS difference between 1080p and 4K Ultra suggests that the RX 7900 XT's rendering workload is the primary bottleneck at higher resolutions.

At Low settings, the scaling pattern is similar but with higher absolute numbers. The average FPS at 1920x1080 is 340, which drops to 220.8 at 2560x1440 and then to 121 at 3840x2160. This indicates that even when the graphical load is minimized, the GPU still governs performance, as the CPU is capable of feeding frames at a much higher rate. The fact that the 1080p Low result is 2.8 times higher than the 4K Low result underscores that resolution is the dominant factor in this configuration.

The data also shows that the gap between settings widens at lower resolutions. At 3840x2160, the difference between Low and Ultra is 47.8 FPS, whereas at 1920x1080, that same gap expands to 139.3 FPS. This behavior is characteristic of a system where the CPU has ample headroom; at 1080p, the GPU is the limiting component, and the impact of each settings tier is fully expressed. At 4K, the GPU is already saturated, so the relative performance loss from higher settings is compressed.

CPU Role

The AMD Ryzen 7 9800X3D is built on the Zen 5 architecture with 8 cores and 16 threads, featuring a base clock of 4.70 GHz and a boost clock of 5.20 GHz. In Doom, which is known for being moderately threaded, this CPU provides a substantial foundation for high frame rates. The benchmark results show a single-thread score of 1212 in 3dmark and a multi-thread score of 10081 in the 16-thread test, indicating strong per-core performance that directly benefits this game's engine.

The CPU's 96 MB of shared L3 cache is a notable feature, as it helps maintain high instruction throughput in gaming workloads. The data supports this by showing that at 1920x1080 Low, the combo achieves 340 FPS, a figure that is unlikely to be CPU-limited in most scenarios. The 3dmark 2-thread score of 2394 and 4-thread score of 4669 suggest that even with fewer active threads, the processor can sustain high clocks and efficient execution.

Comparing to its nearest rivals, the Ryzen 7 9800X3D posts an average benchmark score of 37780, which is nearly identical to the Intel Xeon 6353P at 37811 (delta -0.1%) and the Intel Core Ultra 5 225 at 37831 (delta -0.1%). It trails the Intel Core i9-13900HK by 0.6% and the Intel Core i5-13600KF by 0.7%. These marginal differences indicate that the CPU is not the differentiating factor in this combo's performance; instead, it provides a consistent, high-level baseline that allows the GPU to operate at its full potential.

GPU Role

The AMD Radeon RX 7900 XT is the primary driver of performance in this pairing, equipped with 20 GB of GDDR6 memory on a 320-bit bus, delivering a bandwidth of 800.0 GB/s. The GPU's boost clock of 2394 MHz and game clock of 2025 MHz enable it to process the demanding Vulkan-based rendering in Doom efficiently. With 5376 shading units and 192 ROPs, the card has ample throughput for high-resolution textures and effects.

At 3840x2160 Ultra, the average FPS of 73.2 demonstrates that the GPU is working near its limits, as the memory bandwidth and compute resources are fully engaged. The 20 GB VRAM capacity is more than sufficient for this title, but the data shows that the raw fill rate and shading capability dictate performance at this resolution. The pixel rate of 459.6 GPixel/s and texture rate of 804.4 GTexel/s are key specifications that correlate with the observed scaling from 1080p to 4K.

The GPU's average benchmark score of 38358 places it in the 82nd percentile among all GPUs. Its nearest rival, the NVIDIA GeForce RTX 5080 Mobile, scores 38349 with a delta of 0%, indicating a statistical tie. The NVIDIA CMP 70HX is 0.3% ahead, while the NVIDIA GeForce RTX 4080 Mobile is 0.6% behind. These comparisons show that the RX 7900 XT holds its own against modern competitors, though the measured FPS in Doom is what ultimately matters for this analysis.

How This Combo Ranks

This specific combination of the Ryzen 7 9800X3D and RX 7900 XT ranks 327 out of 1681 tested combos in Doom, placing it in the top 19.5% of all configurations. This ranking is notable because it demonstrates that while the hardware is powerful, there are many other combinations that achieve higher frame rates in this particular game. The rank suggests that Doom's engine is highly optimized for a wide range of hardware, and the limiting factor for this combo is likely the GPU at higher resolutions.

The data indicates that this combo is better suited for high-refresh-rate 1440p gaming than for 4K supremacy. At 2560x1440 High, the average FPS of 162.5 is well above the 144 Hz threshold, while at 3840x2160 High, the 84.9 FPS average is still playable but not competitive with the top-ranked combos. The rank of 327 reflects this balanced capability, as it outperforms most systems but falls short of those equipped with higher-end GPUs or more optimized configurations.

The CPU's percentile rank of 90 and the GPU's percentile rank of 82 suggest that the processor is slightly stronger relative to its peers than the graphics card. This imbalance means that in CPU-light scenarios, the combo excels, but in GPU-heavy scenes, it is the RX 7900 XT that holds the system back from higher rankings.

Settings Recommendations

For the best balance of visual fidelity and performance, the High preset at 2560x1440 is the recommended configuration. This combination yields an average FPS of 162.5, which is smooth on high-refresh-rate monitors while maintaining a high level of graphical quality. The data shows that stepping up to Ultra at this resolution reduces the average to 131.2 FPS, a 19.3% drop that may not justify the marginal visual improvements in Doom.

At 1920x1080, the High preset delivers 251.6 FPS, which is ideal for competitive play on 240 Hz displays. The Ultra preset at 200.7 FPS is also viable, but the data shows that the performance cost is significant relative to the visual gains. For users prioritizing maximum frame rates, the Low preset at 340 FPS is the top choice, but this sacrifices too much visual quality for most players.

At 3840x2160, the Medium preset at 104.5 FPS is the sensible choice, as it provides a solid 100+ FPS experience without the steep drop to 73.2 FPS seen at Ultra. The High preset at 84.9 FPS is acceptable for 60 Hz displays, but Medium offers a better frame time consistency for the resolution. The data does not support using Ultra at 4K unless a 60 FPS cap is acceptable, as the 73.2 FPS average leaves little headroom for demanding scenes.

Measured FPS Breakdown

At 1920x1080, the measured average frame rates are as follows: Low settings achieve 340 FPS, Medium settings achieve 297.4 FPS, High settings achieve 251.6 FPS, and Ultra settings achieve 200.7 FPS. The progression shows a nearly linear scaling between presets, with each step up in quality costing roughly 40-50 FPS. This resolution is clearly GPU-bottlenecked, as the CPU has ample headroom to feed the graphics card.

At 2560x1440, the results are 220.8 FPS for Low, 191.7 FPS for Medium, 162.5 FPS for High, and 131.2 FPS for Ultra. The relative gaps between settings narrow slightly compared to 1080p, indicating that the GPU is beginning to become the limiting factor. The difference between Low and Ultra here is 89.6 FPS, which is a smaller absolute gap than at 1080p but still substantial.

At 3840x2160, the data shows 121 FPS for Low, 104.5 FPS for Medium, 84.9 FPS for High, and 73.2 FPS for Ultra. The scaling is more compressed, with a 47.8 FPS difference between the lowest and highest settings. This pattern confirms that at 4K, the RX 7900 XT is operating at its performance ceiling, and the CPU's capabilities are no longer the primary constraint on frame rates.
