Doom

Resolution Scaling

The measured frame rates across the three tested resolutions reveal a system that scales predictably, but with a notable inflection point as pixel count rises. From 1080p to 1440p, the average FPS at Ultra settings drops from 145 to 94, a 35% reduction. Moving from 1440p to 4K at Ultra, the average falls further to 51, another 46% drop. This steepening decline as resolution increases points directly to the GPU as the primary performance limiter at higher pixel densities.

At 1080p, the frame rates are exceptionally high across all settings, with the Low preset reaching 242 FPS average. This suggests that at this resolution, the CPU and GPU combination has ample headroom, and the workload is not heavily taxing either component. The gap between Low and Ultra at 1080p is 97 FPS (242 vs 145), showing that the settings menu has a substantial impact on output even when the absolute numbers are high.

The 1440p results show a more balanced picture. The Medium preset delivers 136 FPS average, while High sits at 115 FPS. These numbers indicate that the system is still delivering very playable performance, but the scaling between settings is compressing compared to 1080p. The jump from Medium to Ultra at 1440p costs 42 FPS, which is a larger absolute penalty than the 65 FPS penalty at 1080p for the same settings change.

At 4K, the system begins to struggle at the highest settings. The Ultra preset averages 51 FPS, which is just above the threshold for smooth gameplay in a fast-paced FPS. The Low preset at 4K averages 85 FPS, showing that even with reduced graphical loads, the pixel count alone keeps the GPU heavily occupied. The scaling from Low to Ultra at 4K is 34 FPS (85 to 51), the smallest absolute spread across all resolutions, further confirming that the GPU's raw throughput is the binding constraint.

GPU Role

The AMD Radeon RX 6750 XT is built on the RDNA 2.0 architecture with a Navi 22 chip manufactured on a 7 nm process. It carries 12 GB of GDDR6 memory on a 192-bit bus, yielding 432.0 GB/s of memory bandwidth. The base clock is 2150 MHz with a boost clock of 2600 MHz, and the GPU features 2560 shading units, 160 texture mapping units, and 64 raster output units. Its 40 ray tracing cores and 13.31 TFLOPS of FP32 compute provide the raw horsepower for modern game workloads.

In Doom, the GPU's VRAM capacity is more than sufficient. The game's texture and geometry demands at 4K Ultra do not appear to stress the 12 GB pool, as the performance degradation from 1440p to 4K is consistent with what one would expect from pure rasterization load rather than memory capacity throttling. The 432.0 GB/s bandwidth is adequate for the tested configurations, as evidenced by the smooth scaling between settings at each resolution.

The GPU benchmark data shows a 3DMark Steel Nomad DX12 score of 2548, which places it in the 71st percentile of all GPUs. Its nearest rivals in the database include the AMD Radeon R9 M395X (0.5% higher score), AMD FirePro W7100 (0.6% higher), and AMD FirePro D700 (0.7% higher), showing that the RX 6750 XT sits in a tightly contested performance tier. The NVIDIA GeForce RTX 3080 Ti Mobile is 1.1% behind, which is notable given the different market segments.

The GPU's clock behavior is reflected in the 4K results. At 4K Medium, the average FPS is 74, which is 23 FPS higher than 4K Ultra. This suggests that the boost clock can sustain higher frequencies when the shader load is less intense, allowing the GPU to maintain better throughput. The 4K Low result of 85 FPS further confirms this, as the reduced settings allow the GPU to operate closer to its maximum capability.

How This Combo Ranks

The combination of the AMD Ryzen 7 9700X and AMD Radeon RX 6750 XT ranks 1696 out of 3712 tested combos in Doom, placing it in the 54th percentile of all combinations. This mid-pack ranking reflects a pairing that is well-matched for 1440p gaming but falls behind more powerful GPU configurations at higher resolutions.

The CPU's individual standing is much stronger. The Ryzen 7 9700X sits in the 86th percentile of all CPUs, with an average benchmark score of 37943. Its nearest rivals are tightly clustered: the Intel Core i9-14901E is 0.1% ahead, the AMD Ryzen AI 9 HX 370 is 0.1% ahead, the Intel Core 5 211E is 0.3% ahead, and the AMD Ryzen AI Embedded P132 is 0.4% ahead. This indicates that the CPU is performing near the top of its class, and it is not the limiting factor in this combo's ranking.

The GPU, by contrast, sits in the 71st percentile of all GPUs. Its average benchmark score is 26011, with the nearest rivals being within 0.5% to 1.1% of its score. This lower relative standing compared to the CPU suggests that the combo rank is dragged down by the GPU's mid-tier positioning. In a game like Doom, which can be GPU-intensive at high resolutions, this imbalance becomes apparent in the 4K results.

The combo rank of 1696 out of 3712 means that roughly 54% of tested combinations perform better in Doom. This is a reasonable outcome for a mid-range GPU paired with a high-end CPU. The data indicates that if the goal is maximizing frame rates at 4K, a stronger GPU would be necessary to move this combo into the top quartile.

Measured FPS Breakdown

At 1920x1080, the system delivers exceptional performance across all settings. The Low preset averages 242 FPS, with Medium at 210 FPS (minimum 179, maximum 242), High at 178 FPS, and Ultra at 145 FPS. These numbers show that the combo is capable of driving high-refresh-rate monitors at 1080p, with even the most demanding preset staying well above 144 FPS.

The 2560x1440 results show a step down in performance but remain highly playable. Low averages 156 FPS, Medium 136 FPS (minimum 116, maximum 157), High 115 FPS, and Ultra 94 FPS. The Ultra preset is still comfortably above 60 FPS, and the Medium preset's minimum of 116 FPS indicates consistent frame delivery without major drops.

At 3840x2160, the performance becomes more variable. Low averages 85 FPS, Medium 74 FPS (minimum 63, maximum 85), High 62 FPS, and Ultra 51 FPS. The Medium preset's minimum of 63 FPS is noteworthy, as it shows that even in demanding scenes, the system maintains a playable frame rate. The Ultra preset at 51 FPS is borderline for competitive play, but it remains smooth enough for single-player experiences.

The FPS deltas between settings are consistent across resolutions. The difference between Ultra and Medium is 65 FPS at 1080p, 42 FPS at 1440p, and 23 FPS at 4K. This compression at higher resolutions is expected, as the GPU becomes the bottleneck and the relative cost of each quality level diminishes. The gap between Low and Ultra follows a similar pattern: 97 FPS at 1080p, 62 FPS at 1440p, and 34 FPS at 4K.

CPU Role

The AMD Ryzen 7 9700X is an 8-core, 16-thread processor based on the Zen 5 architecture (Granite Ridge), manufactured on a 4 nm process by TSMC. It features a base clock of 3.80 GHz and a boost clock of 5.50 GHz, with a 65 W TDP. The cache hierarchy includes 80 KB of L1 per core, 1 MB of L2 per core, and 32 MB of shared L3 cache. Memory support is DDR5 with dual-channel configuration, providing 89.6 GB/s of bandwidth.

In Doom, the CPU's role is primarily to feed the GPU with draw calls and game logic. The benchmark results show that the 9700X is more than capable of this task. The Cinebench R23 multi-core score of 20485 and single-core score of 2211 indicate strong all-around performance. The Geekbench multi-core score of 17906 and single-core score of 3023 further confirm this. The 3DMark 16-thread score of 9824 and single-thread score of 1280 show that the processor maintains its performance across varying thread counts.

The CPU's nearest rivals in the database are all within 0.4% of its average score, indicating that the 9700X is performing exactly as expected for its tier. This means that in Doom, the CPU is unlikely to be the source of any frame rate limitations. The evidence for this is in the 1080p Low results, where the system reaches 242 FPS average. If the CPU were a bottleneck, the frame rate would plateau at a lower value regardless of the GPU settings.

At 4K, the CPU's influence is even less pronounced. The frame rates at 4K are primarily determined by the GPU's pixel throughput, and the CPU has sufficient headroom to feed the GPU without stalling. The consistent scaling between settings at 4K, with no anomalous dips, supports the conclusion that the CPU is not introducing any frame pacing issues.

Settings Recommendations

For players targeting maximum frame rates at 1080p, the Low preset at 242 FPS average is the clear choice for competitive play, but the Medium preset at 210 FPS offers a substantial visual upgrade with only a 32 FPS penalty. The High preset at 178 FPS remains excellent for high-refresh-rate displays, while Ultra at 145 FPS is still smooth for most users.

At 1440p, the Medium preset provides the best balance of visual quality and performance, averaging 136 FPS with a minimum of 116 FPS. This ensures smooth gameplay even in intense combat sequences. The High preset at 115 FPS is also viable, but the gap to Medium (21 FPS) is significant enough to recommend Medium as the default. The Ultra preset at 94 FPS is playable but leaves less headroom for frame rate dips.

For 4K gaming, the Medium preset at 74 FPS average is the recommended choice, as it delivers a solid experience above 60 FPS with a minimum of 63 FPS. The High preset at 62 FPS is borderline, and the Ultra preset at 51 FPS may cause noticeable stuttering in fast-paced scenes. The Low preset at 85 FPS is the best option for those prioritizing frame rate over visual fidelity, but Medium offers a significant visual improvement for a modest 11 FPS cost.

The data shows that the optimal settings depend heavily on the target resolution. At 1080p and 1440p, the system has enough headroom to run High or Ultra presets while maintaining high frame rates. At 4K, dropping to Medium is necessary to stay above 60 FPS consistently. For players with adaptive sync displays, the Ultra preset at 4K may still be acceptable given the 51 FPS average, but the Medium preset's minimum of 63 FPS provides a more consistent experience.
