GPU Role

The NVIDIA GeForce RTX 5090 D is the dominant component in this pairing. With 32 GB of GDDR7 memory on a 512-bit bus delivering 1.79 TB/s bandwidth, the GPU has massive headroom for any resolution Doom can throw at it. The 1,750 MHz memory clock (28 Gbps effective) and 2,407 MHz boost clock combine with 21,760 shading units to produce 104.8 TFLOPS of FP32 compute power. These specifications translate directly into the measured frame rates.

The GPU's role becomes clearer when comparing settings at the same resolution. At 4K, dropping from Ultra to Low increases average FPS from 102 to 170 — a 68 FPS gain. The RTX 5090 D's 680 texture mapping units and 176 render output units handle texture-heavy scenes efficiently, while the 170 ray tracing cores provide future-proofing even though Doom's original release predates widespread RT adoption.

The 92nd percentile ranking among all GPUs underscores its position. In benchmark comparisons, the RTX 5090 D's 77,712 average score places it just 1.1% ahead of the AMD Radeon RX 6650M XT (76,904) and 1.6% behind the RX 6850M XT (78,940). The GPU's 3DMark Steel Nomad DX12 score of 14,326 and Geekbench Vulkan score of 376,915 demonstrate strong API-level performance that translates to real-world FPS.

Memory bandwidth is the key enabler. The 1.79 TB/s figure means the GPU can feed its 21,760 shading units without starvation, even at 4K with high-quality textures. The 32 GB capacity exceeds any current game requirement, ensuring no texture swapping or compression artifacts at any setting.

Resolution Scaling

The measured data shows clear scaling patterns across 1080p, 1440p, and 4K. At High settings, the average FPS drops from 357 at 1080p to 231 at 1440p to 125 at 4K. This 232 FPS drop from 1080p to 4K represents a 65% reduction, which is steeper than the pixel count increase alone would suggest — indicating the GPU becomes progressively more stressed at higher resolutions.

Low settings show similar scaling: 433 FPS at 1080p, 314 at 1440p, and 170 at 4K. The 1080p to 4K drop here is 263 FPS (61% reduction). Interestingly, the percentage drop is slightly less on Low settings, suggesting that at lower graphics loads, the CPU begins to play a more significant limiting role at 1080p.

The 1080p to 1440p scaling is particularly revealing. At High settings, the drop from 357 to 231 FPS is 35%. At Low settings, the drop from 433 to 314 FPS is 27%. The smaller percentage drop at Low settings indicates the CPU is starting to limit performance at 1080p Low, where the GPU has less work to do and can't fully stretch its legs.

At 4K, the GPU is clearly the limiting component. The RTX 5090 D's 1.79 TB/s bandwidth and 104.8 TFLOPS compute are fully utilized, and the frame rates scale more predictably with settings changes. The 4K Ultra to Low gap of 68 FPS (102 to 170) is substantial but not as dramatic as the 141 FPS gap seen at 1080p.

The Medium settings data provides the only min/max FPS measurements in the dataset. At 4K Medium, the range spans 126 to 170 FPS with an average of 148. At 1440p Medium, the range is 232 to 314 FPS averaging 273. At 1080p Medium, the range is 350 to 474 FPS averaging 412. These ranges show frame time consistency improves as resolution decreases.

Measured FPS Breakdown

1080p Resolution:

• Low: 433 FPS average
• Medium: 412 FPS average (350 min, 474 max)
• High: 357 FPS average
• Ultra: 292 FPS average

The 1080p results show the full range of GPU capability. Even at Ultra settings, the system delivers 292 FPS — far beyond any 60Hz or 144Hz display's refresh rate. The gap between Low and Ultra is 141 FPS, with each settings tier costing roughly 35-55 FPS.

1440p Resolution:

• Low: 314 FPS average
• Medium: 273 FPS average (232 min, 314 max)
• High: 231 FPS average
• Ultra: 189 FPS average

At 1440p, the system maintains triple-digit FPS even on Ultra. The Low to Ultra gap narrows to 125 FPS (314 to 189). The Medium settings show a 232 FPS minimum, which is still well above any display's refresh rate. The 189 FPS Ultra result demonstrates that even maximum quality at 1440p leaves significant headroom.

4K Resolution:

• Low: 170 FPS average
• Medium: 148 FPS average (126 min, 170 max)
• High: 125 FPS average
• Ultra: 102 FPS average

At 4K, the system finally shows meaningful differences between settings. The Ultra result of 102 FPS is still above 100 FPS, making it viable for high-refresh 4K displays. The Low to Ultra gap of 68 FPS (170 to 102) is the smallest percentage-wise across resolutions, confirming the GPU is the limiting factor at 4K.

The data across all resolutions shows a consistent pattern: the RTX 5090 D delivers playable frame rates at every setting and resolution combination tested. The only scenario where the system approaches a performance ceiling is 4K Ultra at 102 FPS, which still exceeds most displays' capabilities.

Settings Recommendations

For 4K displays, Ultra settings at 102 FPS average provide the best visual experience. The performance remains above 100 FPS, which is sufficient for most high-refresh displays. If a user prefers higher frame rates, High settings at 125 FPS offer a 23 FPS improvement with minimal visual degradation. Medium at 148 FPS is the sweet spot for 144Hz 4K displays, though the 126 FPS minimum should be considered.

For 1440p displays, Ultra settings at 189 FPS are the clear recommendation. The system has enough headroom that maximum quality doesn't compromise performance. Even the 1440p Ultra result is well above the 144Hz threshold, making this the optimal choice for most users. High settings at 231 FPS benefit only those with 240Hz or faster displays.

For 1080p displays, Ultra settings at 292 FPS are recommended without hesitation. The system delivers massively high frame rates even at maximum quality. The 292 FPS result exceeds every high-refresh display currently available, so there's no reason to sacrifice visual quality for additional performance.

The Medium settings data provides interesting insights. At every resolution, Medium offers a significant FPS boost over High: 55 FPS at 1080p (412 vs 357), 42 FPS at 1440p (273 vs 231), and 23 FPS at 4K (148 vs 125). However, the visual quality difference between Medium and High in Doom is noticeable, so this trade-off may not be worth it given the already-high frame rates.

The 4K Medium result of 148 FPS with a 126 FPS minimum is the only configuration that might cause concern for 144Hz display owners. The minimum FPS falls below the 144Hz threshold, potentially causing occasional dropped frames. For these users, High settings at 125 FPS average with presumably similar or better frame pacing might be more consistent.

CPU Role

The AMD Ryzen 5 7600X provides the processing foundation for this system. With 6 cores and 12 threads on the Zen 4 architecture, the CPU delivers strong single-thread performance that Doom's engine favors. The 4.70 GHz base clock and 5.30 GHz boost clock ensure responsive gameplay, while the 32 MB shared L3 cache keeps frequently accessed data close to the cores.

The CPU's benchmark results paint a clear picture. The Cinebench R23 single-core score of 1,965 and multi-core score of 15,236 show balanced performance. The Geekbench scores of 2,603 single-core and 13,858 multi-core reinforce this. The 3DMark tests show scaling from 1,060 single-thread to 6,879 at 16 threads, with the 4-thread score of 3,796 being particularly relevant for games that use a handful of threads.

The CPU's 79th percentile ranking among all CPUs places it in the upper tier. Its nearest rivals — the AMD Ryzen 7 5700X and Intel Core i5-12600K — both average 27,578 in benchmarks, a mere 0.2% difference from the 7600X's 27,636 average. The AMD Ryzen 5 8500GE trails by 0.3% with 27,712, while the AMD Ryzen 7 5800 leads by 0.4% with 27,535.

In Doom specifically, the CPU's role becomes evident at 1080p Low settings. The 433 FPS result suggests the CPU is keeping pace with the GPU's output. The relatively small FPS drop from Low to Medium at 1080p (433 to 412) indicates the GPU is starting to become the limiting factor even at 1080p.

The Passmark results show the CPU's versatility: 84,749 in integer math, 51,025 in floating point math, and 37,726 in random string sorting. The 317,862 data compression score and 18,543 data encryption score indicate strong general-purpose performance. These scores suggest the CPU won't bottleneck the GPU in Doom at any resolution or settings combination tested.

The 5 nm process node and 6,570 million transistors on a 71 mm² die contribute to the CPU's efficiency. The 105 W TDP allows the processor to sustain boost clocks during extended gaming sessions. The DDR5 memory support with dual-channel configuration and 83.2 GB/s bandwidth provides sufficient memory throughput for the GPU to receive data without delays.

The CPU's 12 threads handle Doom's multi-threaded workload effectively. The 3DMark 8-thread score of 5,715 shows strong scaling from the 4-thread result of 3,796, indicating good thread utilization. The maximum threads score of 6,845 shows the CPU can leverage all available threads when needed.

At higher resolutions and settings, the CPU's role diminishes as the GPU becomes the bottleneck. The 4K results show the RTX 5090 D doing most of the heavy lifting. However, the CPU's strong single-thread performance ensures that even at 4K, the system doesn't experience frame drops due to CPU limitations. The 4K Medium minimum FPS of 126 suggests stable frame delivery.

The Ryzen 5 7600X's 79th percentile ranking might seem modest, but its performance in Doom exceeds expectations. The combination of high clocks, efficient architecture, and sufficient cache makes it an ideal match for the RTX 5090 D in this game. The 0.2% delta from its nearest rivals in average benchmark scores shows that CPU choice within this performance tier has minimal impact on Doom's frame rates.
