Doom

The AMD Ryzen 7 5800XT paired with the AMD Radeon RX 7900 XTX delivers an exceptionally strong performance profile in Doom (2016), a title whose fast-paced, id Tech 6 engine scales impressively with high-end hardware. Across all tested resolutions and settings, this combination never dips below 76 FPS, indicating a system that is well-balanced for both high-refresh-rate 1440p gaming and smooth 4K experiences. The data reveals a clear pattern of performance degradation as resolution increases, but the magnitude of that drop is heavily influenced by the graphics settings preset, offering distinct insights into the workload distribution between the CPU and GPU.

Resolution Scaling

The measured FPS data shows a predictable yet informative scaling pattern from 1080p to 4K. At the "Low" settings preset, the average frame rate drops from 365.1 FPS at 1920x1080 to 233.9 FPS at 2560x1440, and finally to 129.2 FPS at 3840x2160. This represents a significant 64.6% performance reduction from 1080p to 4K, which is substantial but still leaves the game highly playable at all resolutions. The "Ultra" preset shows a similar trend but with a smaller absolute drop: from 218.7 FPS at 1080p to 141.4 FPS at 1440p, and down to 76 FPS at 4K. The relative scaling here is steeper, with 4K performance being only 34.8% of the 1080p figure.

This pattern strongly suggests that at lower resolutions like 1080p, the AMD Ryzen 7 5800XT is the limiting component. The 365.1 FPS at Low settings is a massive frame rate that likely approaches the ceiling of what the CPU's 8 cores and 16 threads can feed to the GPU. As resolution increases, the rendering load shifts to the RX 7900 XTX, and the FPS drops become more pronounced, indicating that the GPU is now the primary bottleneck. The gap between Low and Ultra at 1080p is 146.4 FPS, while at 4K, this same gap narrows to 53.2 FPS. This compression of frame rates at higher resolutions is classic evidence of a system transitioning from a CPU-bound state to a GPU-bound state, with the RX 7900 XTX's raw compute power becoming the decisive factor.

How This Combo Ranks

This specific configuration of the AMD Ryzen 7 5800XT and AMD Radeon RX 7900 XTX achieves a combo rank of 247 out of 1681 tested combinations in Doom. This places it in the top 14.7% of all tested system pairings, which is an impressive result for a high-end desktop setup. The rank reflects the synergy between the CPU and GPU, and the data suggests that this pairing is well-optimized for the game's engine. While the RX 7900 XTX is a top-tier GPU, its performance in this title is not entirely surprising given its 85th percentile ranking among all GPUs and its average benchmark score of 44019. The CPU, ranking in the 86th percentile with an average benchmark score of 29774, also contributes significantly to this strong overall position. The fact that this combo is not higher in the rankings likely points to the existence of even more powerful CPUs, such as those with more cores or higher clock speeds, which could push frame rates even higher in CPU-bound scenarios at 1080p.

Measured FPS Breakdown

At 1920x1080, the system delivers exceptional performance. The Low preset leads with 365.1 FPS, followed by Medium at 315.7 FPS, High at 268.2 FPS, and Ultra at 218.7 FPS. All presets are well above the 144 Hz refresh rate, making this resolution ideal for competitive play. Moving to 2560x1440, the frame rates remain high but show a clear step down. Low settings yield 233.9 FPS, Medium 205.8 FPS, High 175.8 FPS, and Ultra 141.4 FPS. The Ultra preset at 1440p is still very smooth, though it is the first point where the system dips below the 144 FPS mark. At 3840x2160, 4K gaming is viable but requires settings adjustments. The Low preset provides a solid 129.2 FPS, Medium offers 108.7 FPS, and High delivers 93.5 FPS. The Ultra preset at 4K drops to 76 FPS, which is still playable but no longer takes full advantage of a high-refresh-rate monitor. The data shows a consistent scaling pattern, with each increase in resolution or settings tier resulting in a predictable FPS penalty.

GPU Role

The AMD Radeon RX 7900 XTX is the dominant component in this pairing, and its specifications explain the strong performance at high resolutions. Its 24 GB of GDDR6 memory on a 384-bit bus provides a massive 960.0 GB/s of bandwidth, which is critical for feeding the GPU's 6144 shading units. The GPU's boost clock of 2498 MHz and game clock of 2365 MHz ensure it can sustain high throughput. In Doom, the GPU's role becomes increasingly important as resolution and settings increase. The FPS drop from 1080p to 4K is steep, indicating the GPU is being pushed to its limits at 4K Ultra. The RX 7900 XTX's FP32 performance of 61.39 TFLOPS is substantial, but the data shows that even this level of compute power cannot maintain 100+ FPS at 4K Ultra in this title. The GPU's 85th percentile ranking among all GPUs and its average benchmark score of 44019, which is only 0.8% behind the NVIDIA GeForce RTX 4090 Mobile, confirm its position as a high-end part. The fact that this GPU is now end-of-life suggests that its successor will need to offer significant improvements to handle future titles at 4K Ultra.

Settings Recommendations

For the best overall experience, the High settings preset at 2560x1440 offers an excellent balance, delivering 175.8 FPS. This is a significant improvement over the Ultra preset's 141.4 FPS, with only a small visual penalty. For users with a 144 Hz monitor, the Medium preset at 1440p (205.8 FPS) is also a strong choice, providing a large FPS buffer while still offering good visual quality. At 4K, the High preset is the most balanced, delivering 93.5 FPS. The Ultra preset at 4K (76 FPS) is playable but not ideal for fast-paced action. The data suggests that the "Ultra" preset in Doom carries a heavy performance cost. Moving from High to Ultra at 1080p costs 49.5 FPS, at 1440p it costs 34.4 FPS, and at 4K it costs 17.5 FPS. This diminishing penalty at higher resolutions indicates that the Ultra preset adds a significant load that the GPU can only handle when it is not already fully saturated. For the highest frame rates, the Low preset at 1080p (365.1 FPS) is the clear winner, but it sacrifices visual fidelity for a frame rate that is likely beyond the refresh rate of most monitors.

CPU Role

The AMD Ryzen 7 5800XT, with its 8 cores and 16 threads based on the Zen 3 architecture, plays a crucial role in achieving the high frame rates seen at 1080p. Its boost clock of 4.80 GHz and base clock of 3.80 GHz allow for strong single-threaded performance, which is essential for game logic and draw calls. The CPU's Cinebench R23 multi-core score of 23794 and single-core score of 3359 demonstrate its capability. The data shows that at 1080p, the CPU is the primary bottleneck. The FPS at Low settings (365.1) is extraordinarily high, but the ability to push beyond this is limited by the CPU's processing power. This is evident in the relatively small FPS gains from High to Low at 1080p (96.9 FPS) compared to the larger gains from Ultra to High (49.5 FPS). The CPU's 16 threads are well-utilized in Doom, as evidenced by the 3dmark_max_threads score of 7680 being nearly identical to the 3dmark_16_threads score of 7683. This indicates that the game is able to use all available threads effectively. The CPU's performance is comparable to its nearest rivals, with a delta of only 0.1% compared to the AMD Ryzen 7 PRO 5755GE and -0.3% compared to the AMD Ryzen 7 6800HS, confirming that it is a well-balanced processor for this workload.
