Doom

The benchmark data for Doom with the AMD Ryzen 7 3700X and NVIDIA GeForce RTX 5090 reveals a system that is overwhelmingly GPU-limited at higher resolutions, yet shows a surprising CPU bottleneck at 1080p that prevents the full potential of the graphics card from being realized. The combination ranks in the top 10% of all tested configurations, delivering exceptional frame rates across the board, but the scaling pattern indicates that the 8-core, 16-thread processor from the Zen 2 architecture is the limiting factor in the most CPU-sensitive scenarios.

Resolution Scaling

The frame rate progression from 1080p to 4K clearly identifies where the bottleneck shifts. At 1920x1080 with Low settings, the system produces 277.2 FPS. Moving to 2560x1440 at Low settings, the average drops to 240.3 FPS, a reduction of roughly 13%. Continuing to 3840x2160 at Low settings, the average falls to 163.9 FPS, which is a substantial 32% drop from the 1440p figure. This steep decline at 4K indicates the RTX 5090 is being fully utilized, with the pixel throughput demands of the 4K resolution overwhelming the GPU's massive compute resources.

However, the scaling pattern is not uniform across all settings. At Ultra settings, the frame rate drops from 232.7 FPS at 1080p to 180.3 FPS at 1440p (a 22% reduction), then to 99.2 FPS at 4K (a 45% reduction from 1440p). The larger percentage drop at Ultra settings compared to Low settings suggests that the combination of high resolution and demanding visual effects creates a compounding load on the GPU. The 32 GB of GDDR7 memory at 1.79 TB/s bandwidth is more than sufficient to handle the texture and geometry data at 4K, so the bottleneck is purely in the rendering pipeline.

The data shows that at 1080p, the system is partially CPU-limited. The difference between Low (277.2 FPS) and High (249.7 FPS) settings at 1080p is only 27.5 FPS, while at 4K the same settings gap is 44.6 FPS (119.3 vs 163.9). This compressed scaling at 1080p indicates the Ryzen 7 3700X cannot feed frames fast enough to fully saturate the RTX 5090 at lower resolutions, a common pattern with high-end GPUs paired with mid-generation CPUs.

How This Combo Ranks

The AMD Ryzen 7 3700X and NVIDIA GeForce RTX 5090 combination ranks 161st out of 1681 tested combos in Doom, placing it in the 90.4th percentile of all configurations. This top-tier ranking is expected given the GPU's performance class, but the position relative to other combos reveals the CPU's impact. The RTX 5090 alone sits in the 94th percentile among all GPUs, while the Ryzen 7 3700X sits in the 85th percentile among all CPUs. The combined ranking of 161 is lower than the GPU's individual percentile would suggest, indicating that the processor is dragging the overall score down slightly.

In the context of the CPU's nearest rivals, the Ryzen 7 3700X has an average benchmark score of 28631, which is nearly identical to the Intel Core i5-12600 at 28654 (a deltaPct of -0.1%). This means the processor's general compute performance is on par with that specific Intel chip, but the gaming performance in Doom may differ due to architectural nuances. The AMD Ryzen 5 5600XT is also a close competitor with a score of 28591, just 0.1% behind. The performance parity among these CPUs suggests that the 3700X is not a weak link in absolute terms, but it lacks the single-thread headroom needed to push the RTX 5090 to its limits at 1080p.

The combo's rank of 161 out of 1681 demonstrates that this pairing is exceptionally strong for Doom, but it is not at the very top. The systems that rank higher almost certainly pair the RTX 5090 with newer, higher-clocked CPUs that can maintain higher minimum frame rates and better feed the GPU at lower resolutions.

GPU Role

The NVIDIA GeForce RTX 5090 is the dominant component in this pairing, and the benchmark results show it delivering outstanding performance. The GPU operates at a base clock of 2017 MHz and boosts to 2407 MHz, with 21760 shading units and 680 TMUs. These specifications translate to a pixel rate of 423.6 GPixel/s and a texture rate of 1,636.8 GTexel/s, which are more than capable of handling Doom's id Tech 6 engine at maximum settings.

The memory subsystem is a key strength. The 32 GB of GDDR7 memory on a 512-bit bus provides 1.79 TB/s of bandwidth, which is critical for 4K gaming. At 3840x2160 with Ultra settings, the GPU produces 99.2 FPS, which is still well above the 60 FPS target for smooth gameplay. The 28 Gbps effective memory speed ensures that texture streaming and high-resolution assets do not cause stuttering or frame drops.

The GPU's 3DMark Steel Nomad DX12 score of 14411 and PassMark G3D score of 39650 place it in the 94th percentile among all GPUs. This strong synthetic performance translates directly to Doom's measured results, where the GPU is clearly the primary driver of frame rates at 1440p and 4K. The RTX 5090's nearest rival, the RTX 5090 D, has a nearly identical average score of 84241 (0.1% delta), confirming that this is the flagship GPU tier.

Measured FPS Breakdown

At 1920x1080, the system delivers exceptional performance across all settings. The Low preset achieves 277.2 FPS, Medium reaches 265.1 FPS, High produces 249.7 FPS, and Ultra still maintains 232.7 FPS. The spread between Low and Ultra is 44.5 FPS, which is a modest 16% reduction, indicating that even the most demanding settings at 1080p do not stress the GPU significantly.

Moving to 2560x1440, the frame rates remain very high. The Low preset averages 240.3 FPS, Medium hits 227.2 FPS, High reaches 214.9 FPS, and Ultra drops to 180.3 FPS. The gap between Low and Ultra at 1440p is 60 FPS, or 25%, showing that the GPU is starting to feel the load but still has plenty of headroom above the 144 Hz refresh rate common on high-end monitors.

At 3840x2160, the performance is still excellent but shows the expected drop. The Low preset averages 163.9 FPS, Medium produces 142.4 FPS, High achieves 119.3 FPS, and Ultra falls to 99.2 FPS. The Low-to-Ultra spread at 4K is 64.7 FPS, or 39%, which is the largest percentage gap across all resolutions. This confirms that the GPU is the bottleneck at 4K, with the visual complexity of Ultra settings demanding significantly more compute throughput.

CPU Role

The AMD Ryzen 7 3700X is a 8-core, 16-thread processor based on the Zen 2 architecture, running at a base clock of 3.60 GHz and boosting to 4.40 GHz. It has 32 MB of L3 cache and supports DDR4 memory with a dual-channel bus providing 51.2 GB/s bandwidth. The CPU's Cinebench R23 multi-core score of 19087 and single-core score of 2694 place it in the 85th percentile among all CPUs, which is respectable but not top-tier.

In Doom's measured results, the CPU's influence is most apparent at 1080p. The fact that the frame rate at Ultra settings (232.7 FPS) is only 44.5 FPS lower than at Low settings (277.2 FPS) suggests that the CPU is struggling to maintain its maximum frame output. The engine's draw call processing and game logic run on the CPU, and the Ryzen 7 3700X's single-thread performance, while solid, cannot keep pace with the RTX 5090's ability to render frames at these extreme rates.

The CPU's performance relative to its nearest rivals shows it is not a significant outlier. The Intel Core i5-12600 has an average score of 28654, which is a deltaPct of -0.1% compared to the Ryzen 7 3700X's 28631. In practical terms, this means the two processors have nearly identical overall benchmark performance. The AMD EPYC 7203P is 0.2% ahead, while the AMD Ryzen 5 5600XT is 0.1% behind. These close margins indicate that the 3700X is a well-balanced processor, but it lacks the higher boost clocks or newer architecture advantages that would push it ahead in gaming workloads.

Settings Recommendations

For 4K gaming, the High preset at 3840x2160 provides an average of 119.3 FPS, which is excellent for a high-refresh-rate display and represents the best balance between visual quality and performance. The Ultra preset at 99.2 FPS is still smooth for most players, but the 20 FPS gain from dropping to High is substantial for competitive play. The Medium preset at 142.4 FPS is a viable option for players seeking maximum frame rates on a 144 Hz 4K monitor, but the visual fidelity reduction is noticeable.

At 2560x1440, the Ultra preset achieves 180.3 FPS, which fully saturates a 144 Hz display with headroom to spare. There is no practical reason to drop below High settings at this resolution, as the Ultra preset's 180.3 FPS is already far above the refresh rate of most monitors. The Medium preset at 227.2 FPS and Low at 240.3 FPS are only useful for players with 240 Hz displays who prioritize frame rate over visual quality.

For 1080p gaming, the Ultra preset at 232.7 FPS is the recommended choice, as it delivers the best visual experience while still maintaining frame rates that exceed the refresh rate of the vast majority of monitors. The performance gap between Low and Ultra at this resolution is small, so there is no reason to sacrifice visual quality. The CPU limitation at 1080p means that the GPU is not the primary constraint, and the system's frame rate ceiling is determined by the Ryzen 7 3700X's ability to process game logic. Overall, the data indicates that this combo excels at 1440p and 4K, where the RTX 5090 can stretch its legs, while 1080p performance is held back by the CPU.
