Doom

The AMD Ryzen 9 9950X3D paired with the NVIDIA GeForce RTX 5080 delivers exceptionally high frame rates in Doom, a 2016 FPS title that remains a demanding benchmark for modern hardware. This combination sits at the 95th percentile of all CPUs and the 87th percentile of all GPUs, and the measured data reflects that top-tier positioning, with the system clearing 4K Ultra at an average of 88 FPS while pushing beyond 400 FPS at 1080p on Low settings. The following analysis breaks down how this combo behaves under different resolutions and settings, using only the measured data and the raw component specifications that are directly relevant to this title.

Resolution Scaling

The data shows a predictable but steep decline in average FPS as resolution increases from 1080p to 4K, which is a classic indicator of the GPU becoming the limiting factor at higher pixel counts. At High settings, the average frame rate drops from 306 FPS at 1920x1080 to 198 FPS at 2560x1440, and then settles at 107 FPS at 3840x2160. That is a roughly 65% reduction in average FPS from 1080p to 4K, which is a typical curve for a GPU-bound scenario in a fast-paced shooter where lighting and geometry load the GPU.

Looking at the same progression on Low settings reveals a similar pattern but with a slightly smaller relative drop, from 416 FPS at 1080p to 269 FPS at 1440p and 146 FPS at 4K. The fact that even the Low preset at 4K only yields 146 FPS—while the same setting at 1080p hits 416 FPS—confirms that resolution scaling is the dominant factor at 4K. The data indicates that the CPU is not the primary limiter here; if the CPU were the bottleneck, the 1080p to 1440p gap would be smaller, but the framerates continue to scale almost linearly with the pixel count.

The step from 1080p to 1440p at each preset shows a consistent reduction: High drops from 306 to 198 FPS, Medium from 363 to 235 FPS, Ultra from 250 to 162 FPS, and Low from 416 to 269 FPS. The consistency across these drops—each roughly a 30–40% decrease—points to a system that is fully GPU-bound at all resolutions, with the CPU's 16 cores and 32 threads remaining well ahead of the render demands. The 4K step is even steeper, with High dropping from 198 to 107 FPS and Medium from 235 to 127 FPS, confirming that the GPU's fill rate and memory bandwidth are the bottleneck at 4K.

The scaling pattern also hints at the GPU's memory interface. The RTX 5080 has a 256-bit bus and 960.0 GB/s of bandwidth, which is sufficient for 1440p but becomes a tighter fit at 4K. The average FPS at 4K Ultra is 88 FPS, while 4K Medium hits 127 FPS, meaning the Ultra preset adds a significant load that the GPU cannot fully cover at 4K, reinforcing that resolution, not CPU, is the limiting component.

How This Combo Ranks

Among all 3,712 tested CPU-GPU combinations in the database, this Doom pairing ranks 175th. The percentile of the CPU is 95, meaning it is better than 95% of all CPUs tested, and it sits in the top 5% of all CPUs, a clear sign that the processor is not holding the system back in this game. The GPU's percentile is 87, which is high but not as elite as the CPU's, and this differential is reflected in the ranking.

The combination's rank of 175 out of 3,712 combos places it in the top 4.7% of all pairings, which is a strong result, but not a top-100 finish. This suggests that while the CPU is near the top, the GPU, while capable, is the more limiting factor in this specific game's engine. The CPU's nearest rivals in average benchmark score are all within 0.4% of its score: the AMD Ryzen 7 PRO 9755 at 0.1% ahead, the AMD Ryzen 7 PRO 9755X3D at 0.1% ahead, the AMD EPYC 8224P at 0.3% ahead, and the Intel Core Ultra 9 285 at 0.4% behind. These delta values are tiny, meaning that any of those CPUs would likely produce nearly identical Doom performance in this combo, as the game's low-core-count engine cannot use the extra cores.

The fact that the CPU's nearest rivals are all within a fraction of a percent of its average score indicates that the CPU is not the differentiator here. The ranking position is therefore more a reflection of how the GPU behaves with a very strong CPU, and the fact that the GPU is in the 87th percentile means it is a solid but not top-tier part, so the combo's 175th rank is expected.

GPU Role

The NVIDIA GeForce RTX 5080 is built on the Blackwell 2.0 architecture with a 5 nm TSMC process and packs 16 GB of GDDR7 memory on a 256-bit bus, giving it 960.0 GB/s of bandwidth. Its base clock is 2295 MHz and boost clock is 2617 MHz, with a peak FP32 of 56.28 TFLOPS. These numbers are directly relevant to Doom's performance because the game's rendering load scales with pixel fill rate and memory bandwidth, and the GPU's 112 ROPs and 336 TMUs handle the texture and pixel work.

The measured FPS at Medium settings shows the only min/max data in the pack: at 1080p Medium, the min FPS is 308 and max is 417; at 1440p Medium, min 199 and max 270; at 4K Medium, min 108 and max 146. These min-max ranges show that the GPU is not producing stutter-free frames at 4K Medium, but it maintains a 100+ FPS minimum even at that resolution. The fact that the 4K Medium min is 108 FPS, which is above the 4K Ultra average of 88 FPS, suggests the GPU is handling a smooth experience at Medium, while Ultra at 4K is too heavy.

The GPU's memory size of 16 GB is more than enough for Doom's textures, which is a 2016 title, and the 960.0 GB/s bandwidth is likely a key factor in why the 4K Medium average of 127 FPS is so high. The 5080's 84 ray-traced cores are irrelevant for this game, which does not use ray tracing, but the 10752 shading units handle the traditional rendering well. The measured FPS shows that the GPU is the limiting component at 4K, but it is still delivering playable frame rates, with the lowest 4K average of 88 FPS at Ultra, which is a solid result for a high-end GPU.

The GPU's benchmark scores reflect its strengths: its Passmark G3D score is 36565 and its average benchmark score is 56083, with a percentile of 87. Its nearest rivals are the AMD Radeon 8060S (0.6% higher), the AMD Radeon RX 6750 GRE 12 GB (0.7% higher), the AMD Radeon Pro W5700X (2.3% higher), and the AMD Radeon RX 9070 GRE (2.2% lower). These small deltas confirm that the 5080's performance is not far off from its closest competition, but it is not a class-defining part.

Measured FPS Breakdown

The data provides 12 measured rows across three resolutions and four settings. At 3840x2160, the average FPS is 88 at Ultra, 107 at High, 127 at Medium, and 146 at Low. At 2560x1440, the average FPS is 162 at Ultra, 198 at High, 235 at Medium, and 269 at Low. At 1920x1080, the average FPS is 250 at Ultra, 306 at High, 363 at Medium, and 416 at Low.

The Medium preset shows the only min and max FPS values in the dataset. At 4K Medium, the min is 306 and max is 366, giving a range of 60 FPS. At 1440p Medium, min 199 and max 270, range of 71 FPS. At 1080p Medium, min 308 and max 417, a range of 109 FPS. The 1080p range of 109 FPS is the largest, which is expected because at lower resolutions the CPU can deliver a higher peak, but the frame time variance increases as the GPU is less stressed.

The data shows a linear relationship between settings and FPS within each resolution. For example, at 1080p, the Ultra setting is 250 FPS, while Low is 416 FPS—a difference of 166 FPS. At 4K, the same delta between Ultra and Low is 146 FPS (from 146 to 88 FPS), which is a smaller absolute gap but a similar percentage. The Ultra preset at 4K is the only sub-100 FPS average, while all other settings across all resolutions exceed 100 FPS, and most exceed 200 FPS, indicating the system is very capable of high refresh-rate gaming at 1440p or below.

A: The RTX 5080 is in the 87th percentile of all GPUs. Its nearest rival is the AMD Radeon 8060S with a 0.6% higher average score, while the AMD Radeon RX 9070 GRE is 2.2% lower.

Settings Recommendations

Based on the measured data, the best experience for this combo depends on the target resolution. At 1920x1080, the Medium preset provides 363 FPS with a min of 308 and a max of 417, which is the best balance between smoothness and the visual quality—the Ultra preset drops to 250 FPS, which is still high but 113 FPS less. For 1440p, Medium is again the sweet spot with 235 FPS and a min of 199 FPS, while High offers 198 FPS, so Medium has a 37 FPS advantage at this resolution.

At 4K, the choice is between High (107 FPS) and Medium (127 FPS). The Ultra preset at 4K, at 88 FPS, is the only row under 100 FPS, so the data suggests that Ultra is not the recommended setting for 4K gaming if the user wants a consistent 100+ FPS. The Medium setting at 4K provides 127 FPS with a min of 306 and max of 366, which is a good frame range, but the High setting is 107 FPS with no min/max data. Since the Medium setting has a min FPS of 108, it is the only 4K row that has a recorded minimum, which makes it the safer choice for a smooth 4K experience. Overall, the data recommends Medium at 4K, Medium at 1440p, and Medium at 1080p, but the High preset at 1440p (198 FPS) is also a fine choice if visual fidelity is a priority.

CPU Role

The AMD Ryzen 9 9950X3D is a 16-core, 32-thread processor based on Zen 5 architecture, with a base clock of 4.30 GHz and a boost clock of 5.70 GHz. Its 128 MB L3 cache is a massive pool, and its 4 nm process from TSMC. The CPU's benchmark scores show it is a compute powerhouse: a Cinebench R23 multi-core score of 42018 and a single-core score of 2259, a Geekbench multi-core of 26736 and single 3064. The Passmark multi-thread score is 70255, and its average benchmark score is 75779, which is in the 95th percentile of all CPUs.

In Doom, the CPU's role is not a limiting factor. The game is likely GPU-bound, because the FPS scales with resolution, not with CPU load. The CPU's 16 cores and 32 threads are far more than Doom's engine can utilize, which is a 2016 game that was designed for quad-core CPUs. The measured FPS at 1080p Low (416 FPS) and at 1080p High (306 FPS) are both above the 240 Hz refresh rate of most displays, and the CPU's high single-thread performance is reflected in a 3DMark single-thread score of 1292 and a Passmark single-thread score of 4737.

The fact that the CPU's nearest rivals are all within 0.4% of its average score confirms that the CPU is not a differentiator in this game; a lower-end CPU would produce similar FPS. The CPU's high L3 cache of 128 MB and 5.70 GHz boost clock help with the game's draw calls, but the 4K Ultra row of 88 FPS is the only evidence of a CPU limitation, but the 4K scaling pattern is more consistent with a GPU limit. The CPU's role is to not bottleneck the GPU, which it does not, as evidenced by the 175th rank out of 3,712 combos, a top 5% result.
