Doom

The AMD Ryzen 9 9950X3D paired with the NVIDIA GeForce RTX 3080 Ti delivers a commanding performance profile in Doom, with the data showing a system that scales predictably across resolutions and settings. The benchmark results indicate a configuration that prioritizes high refresh rates at 1440p while remaining thoroughly playable at 4K, making it a versatile choice for this fast-paced FPS.

Resolution Scaling

Resolution scaling behavior reveals the shifting balance of load between the CPU and GPU as pixel count increases. At 1920x1080 with High settings, the combo produces 230 FPS on average. Moving to 2560x1440 at the same preset, the average drops to 149 FPS, a reduction of approximately 35%. The final step to 3840x2160 yields 81 FPS, which is roughly a 46% decline from the 1440p figure and a 65% drop from the 1080p result. This steep scaling curve from 1080p to 4K indicates that the RTX 3080 Ti becomes the primary limiting factor as resolution rises, with the GPU's rendering load increasing disproportionately to the pixel count.

The Low preset data further confirms this trend. At 1080p Low, the system reaches 312 FPS, which is an extraordinarily high frame rate that suggests the CPU is capable of feeding the GPU far beyond what most displays can show. At 1440p Low, the average falls to 202 FPS, and at 4K Low, it settles at 109 FPS. The gap between 1080p and 1440p Low is 110 FPS, while the gap between 1440p and 4K Low is 93 FPS, showing that the scaling penalty is relatively consistent in absolute terms but steeper in percentage terms at higher resolutions. This pattern suggests that at 1080p, the CPU's headroom is substantial, but the GPU still manages to keep frame rates exceptionally high.

The Medium preset offers the only complete dataset with minimum and maximum frame rates. At 1080p Medium, the average is 272 FPS with a minimum of 231 FPS and a maximum of 313 FPS. At 1440p Medium, the average drops to 176 FPS with a minimum of 150 FPS and a maximum of 202 FPS. At 4K Medium, the average is 95 FPS with a minimum of 81 FPS and a maximum of 110 FPS. The minimum frame rates at each resolution stay remarkably close to the averages, indicating consistent frame pacing without severe stutters. The 4K Medium minimum of 81 FPS matches the 4K High average exactly, showing that the Medium preset provides a more stable experience at 4K than High does.

Settings Recommendations

The measured rows allow for a clear assessment of which preset provides the optimal balance of visual quality and performance. At 1920x1080, every preset delivers well above 144 Hz, so the choice comes down to visual fidelity. The Ultra preset at 1080p produces 188 FPS, which remains high enough for competitive play. The High preset at 1080p reaches 230 FPS, a 22% improvement over Ultra. Given that the difference between High and Ultra is typically a modest number of effects, the High preset at 1080p offers the best experience per the data, as it keeps frame rates above 200 while retaining substantial visual quality.

At 2560x1440, the recommendations shift. The High preset averages 149 FPS, which is excellent for high-refresh-rate monitors. The Medium preset averages 176 FPS, a 18% increase over High, but the visual downgrade may not be worth the extra frames for most users. The Ultra preset at 1440p drops to 122 FPS, which is still playable but below the refresh rate of many 144Hz displays. The data suggests that High at 1440p is the sweet spot, as it maintains a comfortable margin above 144 FPS while keeping the more demanding visual features enabled.

At 3840x2160, the situation becomes more constrained. The Ultra preset averages 66 FPS, which is below the 70 FPS threshold many consider minimum for smooth play. The High preset at 4K averages 81 FPS, which is a 23% improvement over Ultra and provides a more consistent experience. The Medium preset at 4K averages 95 FPS with a minimum of 81 FPS, which is the strongest recommendation for 4K gaming. The Low preset at 4K reaches 109 FPS, but the visual compromises are significant. For 4K, the Medium preset offers the best measured balance, as it stays above 90 FPS average while maintaining acceptable visual quality.

How This Combo Ranks

The combo ranking places this CPU-GPU pairing at position 963 out of 3712 tested combinations in Doom. This places the configuration in the top 26% of all tested systems, a strong showing for a combination that features a high-end CPU from 2025 and a GPU from 2021. The ranking reflects the RTX 3080 Ti's age relative to newer GPUs, yet the 9950X3D's exceptional CPU performance helps boost the overall standing.

The percentile data for the individual components provides context for this ranking. The CPU sits at the 95th percentile among all CPUs, meaning it outperforms 95% of processors in general benchmark tests. The GPU sits at the 83rd percentile among all GPUs, which is respectable but not top-tier by contemporary standards. The discrepancy between the CPU's elite standing and the GPU's solid-but-not-spectacular position explains why the combo ranks where it does—the CPU is doing everything it can, but the GPU ultimately caps the system's potential in this GPU-bound title at higher resolutions.

The nearest rivals for the CPU all have average scores within 0.4% of the 9950X3D. The AMD Ryzen 7 PRO 9755 is just 0.1% behind, while the AMD Ryzen 7 PRO 9755X3D matches that margin. The AMD EPYC 8224P trails by 0.3%, and the Intel Core Ultra 9 285 is 0.4% behind. This tight grouping indicates that the 9950X3D is at the very top of the CPU performance hierarchy, with no meaningful separation from its closest competitors.

Measured FPS Breakdown

At 1920x1080, the full settings ladder shows a clear progression. Low averages 312 FPS, Medium averages 272 FPS with a minimum of 231 FPS and maximum of 313 FPS, High averages 230 FPS, and Ultra averages 188 FPS. The gap from Low to Ultra is 124 FPS, representing a 40% reduction in performance from the lowest to the highest preset. The step from Low to Medium costs 40 FPS, from Medium to High costs 42 FPS, and from High to Ultra costs 42 FPS, showing a remarkably linear scaling pattern across presets.

The total spread from Low to Ultra is 43 FPS, a 39% reduction that maintains the same proportional scaling as lower resolutions. The step from Low to Medium costs 14 FPS, from Medium to High costs 14 FPS, and from High to Ultra costs 15 FPS. This consistency across resolutions indicates that the rendering cost of each preset tier is proportional regardless of pixel count.

GPU Role

The NVIDIA GeForce RTX 3080 Ti features 12 GB of GDDR6X memory across a 384-bit bus, providing 912.4 GB/s of memory bandwidth. This bandwidth is crucial for Doom, which uses a heavily textured environment that benefits from rapid texture streaming. The GPU's 80 RT cores and 320 tensor cores are less relevant for this title, as Doom does not heavily utilize ray tracing, but the 10,240 shading units do the heavy lifting for rasterization.

The GPU's clock speeds are a base of 1365 MHz and a boost of 1665 MHz, with memory running at 1188 MHz or 19 Gbps effective. These clocks are modest by modern standards, but the GA102 chip's large die size of 628 mm² and 28,300 million transistors provide substantial raw compute. The FP32 performance of 34.10 TFLOPS allows the GPU to handle the demanding lighting and particle effects in Doom at high frame rates.

The GPU's performance percentile of 83 places it above 83% of all GPUs, but its nearest rivals in average benchmark score include the NVIDIA GeForce RTX 5070, which is 2% faster on average. The RTX 3080 Ti holds its own against this newer competitor, which is notable given the architectural generational gap. The 12 GB VRAM capacity is sufficient for Doom at all tested settings, as the game's texture requirements at 4K Ultra do not exceed this allocation.

CPU Role

The AMD Ryzen 9 9950X3D provides 16 cores and 32 threads based on the Zen 5 architecture, built on a 4 nm process by TSMC. The CPU's base clock is 4.30 GHz with a boost clock of 5.70 GHz, and it features a substantial 128 MB of L3 cache. This large cache is particularly beneficial for game performance, as it reduces memory latency for frequently accessed data.

The CPU's 3DMark scores show strong scaling from 2 threads to 16 threads. The 2-thread score is 2549, the 4-thread score is 4963, the 8-thread score is 9259, and the 16-thread score is 16374. The max-thread score of 17184 is only 5% higher than the 16-thread score, indicating that the processor reaches near-peak performance with 16 threads and gains little from additional threads. This is typical for gaming workloads, which rarely utilize more than 8 cores effectively.

In Doom, this CPU's single-thread performance is the key differentiator. The 3DMark single-thread score of 1292 and the Cinebench R23 single-core score of 2259 indicate strong per-core performance. This allows the CPU to maintain high frame rates even at lower resolutions where the GPU is less burdened. The 1080p Low result of 312 FPS demonstrates that the CPU can feed the GPU with frames far beyond what most displays can show, confirming that the 9950X3D is not a bottleneck in this title.
