Doom

The AMD Ryzen 9 9900X3D paired with the NVIDIA GeForce RTX 5090 delivers an exceptionally high-performance experience in Doom, with measured frame rates that scale predictably across resolutions and settings. This combination ranks 45th out of 2,930 tested combos in this game, placing it in the top 1.5% of all configurations. The data shows a system that is overwhelmingly GPU-bound at higher resolutions, while the processor’s strong single-thread performance ensures it never becomes a bottleneck even at 1080p.

Resolution Scaling

The measured FPS data reveals a clear and consistent pattern of performance degradation as resolution increases, which is typical for a game like Doom that relies heavily on fill rate and pixel throughput. At 1080p with High settings, the combo produces 334 FPS average. Moving to 1440p drops this to 216 FPS, a reduction of 118 FPS or approximately 35%. At 4K, the average falls further to 117 FPS, which is 217 FPS below the 1080p result, representing a 65% decrease from the baseline.

This scaling behavior strongly indicates that the NVIDIA GeForce RTX 5090 is the limiting component at higher resolutions, rather than the CPU. The gap between 1080p and 1440p is substantial, but the drop from 1440p to 4K is even more pronounced in absolute terms, suggesting that the GPU’s rendering workload is expanding faster than its ability to compensate. The RTX 5090’s 32 GB of GDDR7 memory and 1.79 TB/s bandwidth are clearly sufficient for 4K, but the sheer pixel count of 3840x2160 (over 8.3 million pixels) taxes the GPU’s shader and ROP throughput.

Interestingly, the scaling between 1440p and 4K is not perfectly linear. At High settings, 1440p yields 216 FPS while 4K yields 117 FPS, a 46% drop. At Low settings, the same resolution change produces 294 FPS down to 159 FPS, a 46% drop as well. This consistency suggests that the game’s engine scales workload proportionally with resolution, and the RTX 5090’s 104.8 TFLOPS of FP32 compute is the primary factor determining these numbers. The CPU’s role, while not irrelevant, becomes secondary once the resolution exceeds 1080p.

CPU Role

The AMD Ryzen 9 9900X3D is a 12-core, 24-thread processor based on the Zen 5 architecture, codenamed Granite Ridge, with a base clock of 4.40 GHz and a boost clock of 5.50 GHz. Its benchmark results show strong multi-threaded performance, with a Cinebench R23 multi-core score of 47,737 and a Geekbench multi-core score of 22,884. Single-thread performance is equally robust, with a Cinebench R23 single-core score of 6,739 and a Geekbench single-core score of 3,041.

In Doom, which is primarily a GPU-bound title at these settings, the CPU’s influence is most visible at 1080p where frame rates are highest. At 1080p Low, the combo achieves 454 FPS average, which is a 120 FPS jump over the 1080p High result of 334 FPS. This 36% improvement from lowering settings suggests that the CPU can feed the GPU fast enough to reach very high frame rates, but the GPU’s rendering pipeline still limits the absolute ceiling. The CPU’s 128 MB of L3 cache likely helps with game logic and draw call processing, but the data does not show a scenario where the CPU becomes a hard bottleneck—even at 454 FPS, the GPU is still the limiting factor.

The processor’s percentile ranking of 91st versus all CPUs indicates it is well above average, but its nearest rivals in average benchmark score—such as the Intel Core Ultra 5 245KF at 55,093 with a delta of -0.6%—show that the 9900X3D is not dramatically ahead in raw compute. This is relevant because Doom does not heavily utilize 24 threads; the game’s engine typically scales to 8-16 threads at most. The 3DMark 8-thread score of 9,002 and 16-thread score of 12,490 suggest that the processor’s mid-thread performance is solid, but the game’s frame rates are more dependent on the GPU. At 4K Ultra, where the average FPS drops to 96, the CPU is almost certainly idle waiting on the GPU to complete frames.

Settings Recommendations

The measured data provides clear guidance on which settings preset offers the best experience, depending on the target resolution and refresh rate. At 1080p, the Low preset delivers 454 FPS average, which is extraordinarily high and suitable for competitive play on high-refresh monitors. However, the jump to Medium yields 396 FPS, a drop of 58 FPS but still far above any conventional display’s refresh rate. High settings at 1080p produce 334 FPS, while Ultra drops to 273 FPS. Given that even Ultra at 1080p maintains 273 FPS, users with 144Hz or 240Hz monitors could comfortably select Ultra for maximum visual fidelity without dropping below refresh rate thresholds.

At 1440p, the situation tightens. Medium settings produce 256 FPS, which remains excellent, while High yields 216 FPS. Ultra drops to 177 FPS, which is still well above 144Hz. The Low preset at 1440p reaches 294 FPS, but the visual compromise is likely not worth the extra 38 FPS over Medium. For most users, Medium or High at 1440p offers the best balance, as the difference between Medium and High is only 40 FPS, while High to Ultra is a 39 FPS drop.

At 4K, the recommendations shift significantly. Medium settings produce 139 FPS with a minimum of 118 FPS and maximum of 160 FPS, which is ideal for 120Hz displays. High settings drop to 117 FPS average, which is still playable but may cause occasional dips below 60 FPS on some scenes. Ultra at 4K produces only 96 FPS, which is below the 120Hz threshold and may result in noticeable stutter on high-refresh panels. Low at 4K reaches 159 FPS, but the visual degradation is severe. Based on the measured rows, Medium at 4K is the optimal preset, as it maintains a minimum FPS of 118, which is above the 60 FPS floor and close to the 120 FPS target.

How This Combo Ranks

The combination of the AMD Ryzen 9 9900X3D and NVIDIA GeForce RTX 5090 achieves a combo rank of 45 out of 2,930 tested combinations in Doom. This places it in the 98.5th percentile, meaning only 44 other configurations perform better in this specific game. The rank is notable because the GPU’s average benchmark score of 79,842 puts it in the 92nd percentile against all GPUs, while the CPU’s 91st percentile ranking is slightly lower. This suggests that the combo’s high rank is driven primarily by the RTX 5090’s exceptional rasterization performance in Doom, which is a title that favors raw GPU throughput.

The GPU’s nearest rivals in average benchmark score include the NVIDIA Tesla P100 PCIe 16 GB with a delta of 0.3% and the AMD Radeon RX 6850M XT with a delta of 1.1%, but these are data center or mobile parts that do not translate directly to gaming performance. The RTX 5090’s 92nd percentile ranking versus all GPUs, combined with the CPU’s 91st percentile, indicates that this combo is near the top of the hardware hierarchy. The 45th rank out of 2,930 combos means that there are a handful of configurations—likely involving even higher-end GPUs or more specialized CPUs—that edge it out, but for practical gaming purposes, this is a top-tier setup.

GPU Role

The NVIDIA GeForce RTX 5090 is the dominant component in this pairing, as evidenced by the benchmark results. Its architecture, Blackwell 2.0, is built on a 5 nm process at TSMC, with 92,200 million transistors on a 750 mm² die. The GPU features 32 GB of GDDR7 memory on a 512-bit bus, providing 1.79 TB/s of bandwidth. Clock speeds are 2,017 MHz base and 2,407 MHz boost, with memory running at 1,750 MHz or 28 Gbps effective. These specifications translate into 104.8 TFLOPS of FP32 compute and 1,636.8 GTexel/s of texture fill rate.

In Doom, the GPU’s role is clearly primary. The measured FPS at 4K Ultra is 96 FPS, which is below the 1440p Ultra result of 177 FPS and the 1080p Ultra result of 273 FPS. This scaling pattern shows that the GPU’s pixel throughput is the limiting factor at 4K, as the 176 ROPs and 423.6 GPixel/s pixel rate are insufficient to maintain higher frame rates at that resolution. The 32 GB VRAM is more than adequate for Doom at any settings, as the game’s texture requirements are modest, and the 1.79 TB/s bandwidth ensures no memory bandwidth bottlenecks.

The GPU’s benchmark scores reinforce its strength. The 3DMark Steel Nomad DX12 score of 18,355 and the Geekbench Vulkan score of 376,728 indicate strong API-level performance, which carries over to Doom’s Vulkan renderer. The Passmark G3D score of 39,650 places it in the 92nd percentile, and the nearest rivals show deltas of less than 1.5%, meaning the RTX 5090 is closely matched with a few other GPUs in synthetic benchmarks. However, in Doom, the RTX 5090’s combination of high clock speeds, massive memory bandwidth, and 21,760 shading units delivers frame rates that are competitive with any other single-GPU solution.

Measured FPS Breakdown

At 1080p, the measured FPS shows a clear hierarchy across settings. Low produces 454 FPS average, which is the highest measured result in the entire dataset. Medium yields 396 FPS with a minimum of 336 FPS and maximum of 455 FPS. High drops to 334 FPS, and Ultra falls to 273 FPS. The spread from Low to Ultra is 181 FPS, representing a 40% reduction in performance when moving to the highest quality preset. The minimum FPS at Medium (336) is still higher than the average FPS at Ultra (273), indicating that even the worst-case frame times at Medium are better than the typical experience at Ultra.

At 1440p, the numbers scale down proportionally. Low achieves 294 FPS, Medium 256 FPS with a minimum of 218 FPS and maximum of 295 FPS, High 216 FPS, and Ultra 177 FPS. The gap between Low and Ultra is 117 FPS, which is a 40% reduction, identical to the 1080p scaling. This consistency suggests that the settings presets affect the GPU’s workload uniformly across resolutions. The Medium preset’s minimum FPS of 218 is notably robust, staying above 200 FPS even in demanding scenes.

At 4K, the performance envelope tightens considerably. Low produces 159 FPS, Medium 139 FPS with a minimum of 118 FPS and maximum of 160 FPS, High 117 FPS, and Ultra 96 FPS. The drop from Low to Ultra is 63 FPS, or 40% again, maintaining the same relative scaling. However, the absolute numbers are lower, and the Medium preset’s minimum of 118 FPS is the only setting that guarantees a consistent 60+ FPS experience at 4K. High at 117 FPS average is borderline, while Ultra at 96 FPS may dip below 60 FPS in heavy scenes, though the data does not provide a minimum for that preset.
