Doom

CPU Role — cores, clocks, and how they relate to this game's results

The AMD Ryzen 9 9950X3D is a 16-core, 32-thread processor built on the Zen 5 architecture (Granite Ridge) using TSMC's 4 nm process. Its base clock is 4.30 GHz with a boost clock of 5.70 GHz, and it carries a 128 MB shared L3 cache. This is a desktop part on the AMD Socket AM5 platform, supporting DDR5 memory via a dual-channel bus with 89.6 GB/s bandwidth. The CPU holds a 96th percentile ranking among all tested processors, with an average benchmark score of 71660.

In synthetic workloads, the 9950X3D demonstrates strong scaling from 2 to 16 threads. Its 3DMark scores progress from 2549 at 2 threads to 9259 at 8 threads, then to 17184 at max threads. Cinebench R23 results show a multicore score of 59712 versus a single-core score of 8430, indicating a roughly 7x multiplier when all cores are engaged. PassMark multithread score reaches 70255, while single-thread sits at 4737. These numbers suggest the CPU is far from a bottleneck in Doom, a title originally released in 2016 that is not known for heavy multi-threaded demand.

The nearest rival in aggregate benchmark score is the Intel Xeon Platinum 8270, which the 9950X3D edges by 0.9%. The AMD Ryzen 9 9950X (non-X3D) trails by 1.8%, while the Intel Core i7-14700KF is 2.2% behind. The only rival ahead is the Intel Xeon 6517P, which leads by 1.9%. These deltas are small, indicating the 9950X3D sits in a tightly contested performance band at the top of the desktop CPU spectrum.

For Doom specifically, the combination of 16 cores and a high boost clock means the CPU can feed frames rapidly. The 32 threads provide ample headroom for any background tasks, but the game's frame pacing will depend more on the GPU. The measured FPS data shows that even at 1080p Low, where CPU load is proportionally highest, the system achieves 190.4 FPS — a level where most CPUs would still keep up, but the 9950X3D's single-thread strength (Cinebench R23 single-core 8430) ensures no stall points.

How This Combo Ranks — use comboRankInGame vs other tested combos

This specific pairing of AMD Ryzen 9 9950X3D with NVIDIA GeForce RTX 3060 Ti ranks 1195 out of 1681 tested combinations in Doom. That places it in the lower third of all combos, which is notable given the CPU's high percentile standing. The rank is driven by the GPU, not the processor. The RTX 3060 Ti sits at the 69th percentile among all GPUs, with an average benchmark score of 25120. Its nearest rivals include the AMD Radeon RX 6700M (0.2% behind), AMD Radeon RX 6600 (0.5% behind), AMD Radeon 890M (0.5% behind), and AMD Radeon RX 580 2048SP (0.7% behind). Every one of these rivals scores within 1% of the RTX 3060 Ti, meaning the GPU is in a dense cluster of mid-range performers.

The combo rank of 1195 out of 1681 suggests that most tested pairings achieve higher FPS in Doom. This is expected because the RTX 3060 Ti, while competent, is not a high-end card. The CPU's 96th percentile rank does not translate into a top combo ranking because the GPU becomes the limiting factor in this game. Benchmark results indicate that pairing this CPU with a stronger GPU would yield a dramatically different rank, but with the current GPU, the combination lands in the 71st percentile of combos (1195/1681). The data shows that the CPU's potential is underutilized in this specific pairing for Doom, as the game's frame rate is constrained by the GPU's throughput rather than the CPU's compute capabilities.

Resolution Scaling — how FPS drops from 1080p to 4K and what it says about the limiting component

Looking at the measured FPS across resolutions at each settings level reveals a clear pattern of GPU limitation. At High settings, the average FPS drops from 141.7 at 1080p to 91.1 at 1440p, then to 48.7 at 4K. That is a 35.7% reduction from 1080p to 1440p, and a further 46.5% reduction from 1440p to 4K. The scaling is steep and consistent with a GPU-bound scenario, where each pixel doubling significantly increases the rendering load.

At Low settings, the same trend appears: 190.4 FPS at 1080p, 126.5 at 1440p, and 69.7 at 4K. The percentage drops are 33.6% and 44.9% respectively. Medium settings show 169.4 at 1080p, 106.8 at 1440p, and 58.4 at 4K, with drops of 37.0% and 45.3%. Ultra settings produce 117.2 at 1080p, 72.9 at 1440p, and 40.3 at 4K, with reductions of 37.8% and 44.7%.

The consistency of these percentage drops across all settings levels is the key signal. If the CPU were the bottleneck, we would expect smaller FPS differences between 1440p and 4K at lower settings, because the CPU work stays roughly constant while GPU work increases. Instead, the FPS drops proportionally to resolution at every settings tier. This indicates the RTX 3060 Ti is the limiting component across the board. The 9950X3D's high single-thread and multicore scores provide no benefit when the GPU cannot render frames fast enough. The data suggests that to improve FPS at any resolution, a GPU upgrade would be more effective than any CPU change.

Measured FPS Breakdown — resolution by resolution, settings by settings, exact numbers

At 1920x1080, the system delivers its highest frame rates. Low settings produce 190.4 FPS average, Medium follows at 169.4 FPS, High drops to 141.7 FPS, and Ultra yields 117.2 FPS. The spread from Low to Ultra is 73.2 FPS, which is a 38.4% reduction. This is a playable range for competitive or fast-paced FPS play, though Ultra remains above 60 FPS.

Moving to 2560x1440, the frame rates decrease noticeably. Low settings average 126.5 FPS, Medium reaches 106.8 FPS, High hits 91.1 FPS, and Ultra falls to 72.9 FPS. The delta between Low and Ultra here is 53.6 FPS, a 42.4% reduction. All settings remain above 60 FPS, making 1440p viable even at Ultra, though the margin narrows.

At 3840x2160, the RTX 3060 Ti begins to struggle. Low settings average 69.7 FPS, which is just above the 60 FPS threshold. Medium drops to 58.4 FPS, High to 48.7 FPS, and Ultra to 40.3 FPS. The gap between Low and Ultra is 29.4 FPS, a 42.2% reduction. Only Low settings maintain a fluid experience at 4K; Medium and above fall below 60 FPS.

The pattern across all resolutions shows that the relative performance gap between Low and Ultra remains consistent at roughly 38-42%, regardless of resolution. This further confirms that the GPU is the dominant factor, as the proportional cost of higher settings does not change with resolution. The 9950X3D's capabilities are not being taxed, as evidenced by the smooth scaling and the fact that even the lowest FPS (40.3 at 4K Ultra) is far above any CPU-induced stutter threshold.

Settings Recommendations

Based on the measured FPS data, the optimal settings depend on the target resolution and desired frame rate. For 1080p, all settings are playable, but the data shows that High settings (141.7 FPS) provide a strong balance between visual quality and performance. Ultra at 1080p (117.2 FPS) is also viable, but the 24.5 FPS drop from High to Ultra may not justify the visual gains for competitive play.

At 1440p, High settings (91.1 FPS) are the sweet spot. Ultra (72.9 FPS) remains above 60 FPS, but Medium (106.8 FPS) and Low (126.5 FPS) offer higher headroom for fast-paced action. For players prioritizing smoothness over visuals, Medium at 1440p delivers a 17.2% FPS increase over High while retaining reasonable quality.

For 4K, the recommendation is clear: Low settings (69.7 FPS) are the only option that maintains a 60+ FPS average. Medium (58.4 FPS) and High (48.7 FPS) fall below the threshold, and Ultra (40.3 FPS) is not recommended for fluid gameplay. The step from Low to Medium at 4K costs 11.3 FPS, which is a significant 16.2% reduction, making Low the best experience per the measured rows.

Across all resolutions, the data indicates that High settings offer the most balanced experience for this combo, providing frame rates that are 21-47% higher than Ultra while staying within 14-26% of Low. For users with 144Hz or 165Hz displays, 1080p Low (190.4 FPS) or Medium (169.4 FPS) are the only presets that can fully utilize such refresh rates. At 1440p, even Low (126.5 FPS) cannot saturate a 144Hz panel, so High (91.1 FPS) is the practical ceiling for quality without sacrificing playability.
