Doom

The AMD Ryzen 7 5700X paired with the AMD Radeon RX 9070 produces a compelling dataset in Doom, with performance scaling that clearly delineates the responsibilities of each component. The measured frames per second across three resolutions and four quality presets show a system that is overwhelmingly GPU-bound at higher settings, yet reveals the CPU's robust headroom at lower resolutions. This analysis breaks down the measured results, placing them in context with the hardware's benchmark profiles and overall combo ranking.

Resolution Scaling

The FPS drop from 1920x1080 to 3840x2160 is steep, but the degree of that drop is highly dependent on the graphics preset. At Low settings, the average frame rate falls from 295.2 FPS at 1080p to 105.1 FPS at 4K, a reduction of approximately 64%. At Ultra settings, the drop is from 175.4 FPS to 63.8 FPS, a reduction of roughly 64% as well. This consistent percentage drop across presets indicates that the scaling burden is primarily on the GPU, as the RX 9070's rendering workload quadruples with the pixel count.

However, the data tells a more nuanced story regarding the system's bottleneck. At 1080p Low, the 295.2 FPS figure suggests the CPU is nearing its limit in feeding the GPU; the Ryzen 7 5700X's 3.40 GHz base and 4.60 GHz boost clocks, combined with its 8 cores and 16 threads, are sufficient to sustain very high frame rates, but the sheer speed of the RX 9070 at this low load means the CPU is the limiting factor. Moving to 1440p Low, the average drops to 190 FPS, a 35.6% decrease, which is a larger relative drop than the 25% increase in pixel count from 1080p to 1440p. This suggests the GPU is becoming the primary constraint at 1440p, even on Low settings.

The scaling from 1440p to 4K is more predictable. At High settings, the average FPS falls from 141.3 to 77.3, a 45.3% reduction, which aligns closely with the doubling of pixel count. This pattern indicates a classic GPU-bound scenario at these higher resolutions and settings. The data implies that for competitive play at extremely high refresh rates, 1080p is the target, but the GPU's performance headroom is best utilized at 1440p where it can still deliver over 116 FPS on Ultra.

Settings Recommendations

The measured rows provide a clear picture of the performance cost of each preset. At 1920x1080, the jump from Low to Medium costs 38.1 FPS (from 295.2 to 257.1), while the jump from Medium to High costs another 38.3 FPS (down to 218.8). The most significant cost comes from High to Ultra, which drops the average by 43.4 FPS to 175.4. At this resolution, even Ultra settings are highly playable, but the data suggests that the visual fidelity gain from Ultra may not justify the performance loss for users seeking maximum frame rates.

The recommendation shifts at higher resolutions. At 2560x1440, the High preset delivers 141.3 FPS, which is an excellent balance of visual quality and smoothness. Ultra at this resolution still provides 116.5 FPS, which is above the 100 FPS threshold many consider ideal for a fast-paced FPS. However, the data shows that the step from High to Ultra at 1440p costs 24.8 FPS, a significant hit. At 3840x2160, High is the most demanding playable setting, with an average of 77.3 FPS. Ultra at 4K drops to 63.8 FPS, which may feel less fluid in a game like Doom. For the best experience per the measured rows, High settings at 1440p appears to be the sweet spot, offering a 141.3 FPS average that balances the GPU's capabilities with the CPU's strong 3dmark_16_threads score of 6858. If 4K is the target, High settings are the reasonable maximum.

How This Combo Ranks

Within the database of 1681 tested combos for Doom, this pairing of the Ryzen 7 5700X and the RX 9070 achieves a rank of 561. This places it in the upper third of all tested configurations, indicating a strong overall performance level. The combo’s ranking is a product of the GPU's high absolute performance, as evidenced by its 25381 Passmark G3D score, and the CPU's respectable multi-threaded capabilities, which are only slightly above its nearest rivals. The data implies that while this is not a top-tier enthusiast combo, it is a potent pairing that outperforms the majority of systems tested in this game.

The GPU's percentile ranking of 79 out of 100 is notably higher than the CPU's percentile of 83, but the combo's rank of 561 out of 1681 suggests that the CPU is not holding the GPU back in a meaningful way for this title. The deltaPct values for the CPU's nearest rivals are all within 0.2% of the 5700X's average score, showing that the choice of CPU around this performance class has a negligible impact on the overall combo ranking. For the GPU, the nearest rivals show slightly negative deltaPct values, meaning the RX 9070 is slightly ahead of them, but the list includes an NVIDIA A2 and a Radeon HD 7970, which are not direct gaming contemporaries, highlighting the GPU's strong position in its own generation.

Measured FPS Breakdown

The complete set of measured average frame rates is as follows. At 1920x1080, the system produces 295.2 FPS on Low, 257.1 FPS on Medium, 218.8 FPS on High, and 175.4 FPS on Ultra. At 2560x1440, the averages are 190 FPS on Low, 167.9 FPS on Medium, 141.3 FPS on High, and 116.5 FPS on Ultra. At 3840x2160, the averages are 105.1 FPS on Low, 89.7 FPS on Medium, 77.3 FPS on High, and 63.8 FPS on Ultra.

The pattern is consistent: each increase in resolution reduces the FPS by a predictable margin, and each increase in settings also takes a toll. The largest single drop across the entire table is from 1080p Low to 1080p Medium, a loss of 38.1 FPS. The smallest drop is from 1440p High to 1440p Ultra, a loss of 24.8 FPS. This data shows that the preset has a slightly more significant impact at lower resolutions, which is likely due to the CPU being able to render frames faster than the GPU can at higher settings. The gap between Low and Ultra at 4K is 41.3 FPS, which is the largest spread in the dataset, indicating that the GPU's workload scales dramatically with both resolution and quality.

GPU Role

The AMD Radeon RX 9070 is the primary driver of the FPS differences across settings. Its 16 GB of GDDR6 memory on a 256-bit bus provides a 644.6 GB/s bandwidth, which is more than sufficient for Doom at any of the tested resolutions, even 4K Ultra. The GPU's boost clock of 2520 MHz and game clock of 2070 MHz show that it can sustain high frequencies under load, which is critical for maintaining the high frame rates seen at 1080p. The data indicates that the GPU is the bottleneck at 4K, as the FPS scales almost linearly with resolution on the same settings.

The RX 9070's compute capabilities, with 3584 shading units and 128 ROPs, are substantial. The Passmark G3D score of 25381 places it in the 79th percentile of all GPUs, confirming its high-end status. However, the nearest rivals listed, such as the NVIDIA A2, are not gaming-focused products, suggesting that the RX 9070's performance is being compared against a wide range of hardware. The data shows that this GPU is well-equipped to handle Doom at high settings, but the transition from 60 FPS to 100+ FPS at 4K depends on the preset, with Low offering 105.1 FPS and Ultra dropping to 63.8 FPS. The GPU's memory capacity appears to be a non-issue, as no data suggests VRAM limitations at any tested configuration.

CPU Role

The AMD Ryzen 7 5700X, with its 8 cores and 16 threads, plays a crucial role in ensuring the GPU is not starved of data. The CPU's benchmark scores are telling: its 3dmark_16_threads score of 6858 and Cinebench R23 multi-core score of 22620 indicate strong multi-threaded performance. In a game like Doom, which can utilize multiple threads for game logic and rendering tasks, this CPU provides ample headroom. The data suggests the CPU is the limiting factor at 1080p Low, where the 295.2 FPS average is likely near the maximum rate the CPU can generate frames, given its 3.40 GHz base and 4.60 GHz boost clocks.

The CPU's single-threaded performance, as measured by a 3dmark_single_thread score of 921 and a Passmark single-thread score of 3385, is also robust. This is important for Doom's main game loop, which often relies on a single primary thread. The CPU's nearest rivals, such as the Intel Core i9-11900KF, show a deltaPct of 0.1%, meaning the 5700X is effectively on par with them in average benchmark score. This indicates that the CPU is not a differentiator in this combo; the performance ceiling is set by the GPU. The CPU's 32 MB of shared L3 cache and support for DDR4 memory are adequate for this game, and the data shows no signs of CPU-induced stuttering or frame pacing issues at any resolution.
