Doom

The AMD Ryzen 9 9950X3D paired with the AMD Radeon RX 9070 delivers a thoroughly capable Doom experience across all tested resolutions, with the data showing a clear progression from high refresh rate dominance at 1080p to solid 4K playability. The measured frame rates indicate a system that scales predictably with both resolution and graphical preset, making it a versatile configuration for this 2016 FPS title.

Resolution Scaling

The frame rate drop from 1920x1080 to 3840x2160 is substantial, but the pattern reveals where the bottleneck lies. At Ultra settings, the system produces 180.8 FPS at 1080p, which falls to 115.2 FPS at 1440p, and further to 64.1 FPS at 4K. This represents a 64.5% reduction from 1080p to 4K, indicating that the GPU becomes progressively more stressed as pixel count increases. However, the drop is not linear; the 1440p result retains 63.7% of the 1080p performance, while the 4K result retains only 35.5%. This steeper falloff at 4K suggests the RX 9070's 16 GB frame buffer and 644.6 GB/s bandwidth are sufficient for the title, but the raw compute throughput becomes the limiting factor at the highest resolution.

At Low settings, the scaling is even more dramatic. The 295.1 FPS at 1080p drops to 191.8 FPS at 1440p and 104 FPS at 4K. The 1080p Low result is particularly telling: it is 63% higher than the 1080p Ultra result, which indicates that the CPU is keeping pace even at very high frame rates. The fact that the 4K Low result (104 FPS) is still higher than the 1080p Ultra result (180.8 FPS) by a factor of 0.58 shows that the GPU workload at 4K Low is roughly comparable to 1080p Ultra, confirming the GPU-bound nature of the higher resolution settings.

The gap between Low and Ultra settings widens with resolution. At 1080p, the difference is 114.3 FPS (295.1 vs 180.8). At 1440p, the difference shrinks to 76.6 FPS (191.8 vs 115.2). At 4K, the difference narrows to 39.9 FPS (104 vs 64.1). This compression at higher resolutions is classic GPU-bound behavior: when the GPU is fully saturated, the relative impact of settings diminishes because the pixel throughput dominates the workload.

CPU Role

The AMD Ryzen 9 9950X3D is a 16-core, 32-thread processor from the Zen 5 architecture, running on the Granite Ridge codename with a 4 nm process. Its base clock of 4.30 GHz and boost clock of 5.70 GHz provide substantial single-thread headroom, which is relevant for Doom's engine. The CPU's 128 MB shared L3 cache is a notable asset, as it helps feed the GPU with data at high frame rates.

Benchmark results place this CPU in the 96th percentile among all tested processors. Its 3DMark single-thread score of 1292 and multi-thread score of 17184 indicate a processor that excels in both lightly-threaded and fully-threaded workloads. The Cinebench R23 scores of 8430 single-core and 59712 multi-core further confirm this balance. Compared to its nearest rivals, the 9950X3D sits 0.9% ahead of the Intel Xeon Platinum 8270, 1.8% ahead of the AMD Ryzen 9 9950X, and 2.2% ahead of the Intel Core i7-14700KF. It trails the Intel Xeon 6517P by 1.9%, but that chip is a server part with different priorities.

In Doom, the CPU's role becomes apparent in the 1080p Low result of 295.1 FPS. This frame rate is high enough that the CPU's per-core performance dictates the ceiling. The 9950X3D's boost clock of 5.70 GHz, combined with the L3 cache, allows it to maintain frame pacing at these elevated rates. The data shows that even at 1080p Ultra (180.8 FPS), the CPU is not the limiting factor; the GPU still has headroom, as evidenced by the fact that dropping to Low settings yields 114.3 FPS higher. This indicates the CPU can handle Doom's draw calls and game logic without becoming a constraint at any tested setting.

GPU Role

The AMD Radeon RX 9070, built on the RDNA 4.0 architecture with the Navi 48 chip, provides 3584 shading units, 224 TMUs, and 128 ROPs. Its 16 GB of GDDR6 memory on a 256-bit bus delivers 644.6 GB/s of bandwidth. The GPU's game clock of 2070 MHz and boost clock of 2520 MHz are the key performance drivers.

The GPU's benchmark profile shows a 79th percentile ranking among all GPUs, with a Passmark G3D score of 25381 and a 3DMark Steel Nomad DX12 score of 6290. Compared to its nearest rivals, the RX 9070 sits 0.2% behind the NVIDIA A2, 0.3% ahead of the NVIDIA Quadro GV100, 0.7% ahead of the AMD Radeon HD 7970, and 0.8% ahead of the AMD Radeon PRO W6400. These deltas are small, indicating that the RX 9070's average benchmark score of 34780 places it in a tightly contested performance band.

In Doom, the GPU's role is most visible in the resolution scaling. The 4K Ultra result of 64.1 FPS is the lowest measured, and it reflects the GPU's compute ceiling at that resolution. The 4K High result of 75.2 FPS is 17.3% higher than Ultra, showing that the GPU has some headroom when pixel shaders are less demanding. The 4K Medium result of 92.5 FPS and 4K Low result of 104 FPS demonstrate that the RX 9070 can comfortably exceed 60 FPS at 4K across all settings, with Low settings approaching the refresh rate of many 4K displays.

The GPU's 16 GB VRAM is ample for Doom, which is a 2016 title and does not have the memory pressure of modern releases. The 644.6 GB/s bandwidth ensures that texture streaming at 4K Ultra does not introduce stutters, as evidenced by the consistent average frame rates across all settings.

How This Combo Ranks

This specific combination of AMD Ryzen 9 9950X3D and AMD Radeon RX 9070 ranks 556th out of 1681 tested combos in Doom. This places it in the top 33.1% of all configurations tested, which is a solid result given that the database includes many higher-end GPU pairings. The rank reflects the GPU's mid-range positioning rather than any CPU limitation; the 9950X3D's 96th percentile CPU ranking shows it is well above average, but the RX 9070's 79th percentile GPU ranking holds the combo back from the top tiers.

The data suggests that this combo is CPU-bottlenecked only at the very highest frame rates. The 1080p Low result of 295.1 FPS is likely near the CPU's practical limit for this game, but the 1080p Ultra result of 180.8 FPS shows the GPU still has substantial room before the CPU becomes the constraint. At 1440p and 4K, the GPU is clearly the limiting component, as the frame rates scale consistently with resolution.

Compared to other combos in the database, this pairing offers a balanced profile. The CPU is overqualified for Doom at 1080p, but the GPU is the primary determinant of the final rank. A user could achieve a higher rank by pairing the 9950X3D with a more powerful GPU, but the current setup delivers playable frame rates at all tested settings and resolutions.

Settings Recommendations

The measured data points to Ultra settings at 1080p and 1440p as the sweet spot for this combo. At 1080p Ultra, the system produces 180.8 FPS, which is well above the 144 Hz refresh rate common on many monitors. At 1440p Ultra, the 115.2 FPS result is still high enough for smooth gameplay on 120 Hz displays, and it offers a significant visual upgrade over High settings.

For 4K gaming, the Ultra preset drops to 64.1 FPS, which is playable but may not satisfy users with high refresh rate 4K panels. The High preset at 4K delivers 75.2 FPS, a 17.3% improvement over Ultra, and this is the recommended setting for 4K if visual fidelity is a priority. The Medium preset at 4K yields 92.5 FPS, which is a more comfortable margin above 60 FPS, but the visual trade-off from Ultra to Medium is noticeable.

If maximizing frame rate is the goal, the Low preset at 1440p (191.8 FPS) and 1080p (295.1 FPS) are the best choices. These settings are ideal for competitive play where frame rate trumps visual quality. The Medium preset at 1440p (167.5 FPS) offers a balanced middle ground, providing 46.4% more performance than Ultra while retaining most of the visual enhancements.

Measured FPS Breakdown

At 1920x1080, the system delivers 295.1 FPS on Low, 259.2 FPS on Medium, 216.1 FPS on High, and 180.8 FPS on Ultra. The progression from Low to Ultra shows a 38.7% performance penalty for the highest settings. The jump from Low to Medium costs 35.9 FPS (12.2%), while Medium to High costs 43.1 FPS (16.6%), and High to Ultra costs 35.3 FPS (16.3%). These steps are relatively uniform, indicating that each preset tier adds a similar GPU workload.

At 2560x1440, the results are 191.8 FPS on Low, 167.5 FPS on Medium, 139.9 FPS on High, and 115.2 FPS on Ultra. The penalty from Low to Ultra is 39.9%, which is slightly larger than at 1080p. The setting steps are 24.3 FPS (12.7%) from Low to Medium, 27.6 FPS (16.5%) from Medium to High, and 24.7 FPS (17.7%) from High to Ultra. The percentage cost of each tier increases as the resolution rises, confirming the GPU-bound nature of the workload.

At 3840x2160, the system produces 104 FPS on Low, 92.5 FPS on Medium, 75.2 FPS on High, and 64.1 FPS on Ultra. The Low to Ultra penalty is 38.4%, which is consistent with the other resolutions. The absolute differences are 11.5 FPS (11.1%) from Low to Medium, 17.3 FPS (18.7%) from Medium to High, and 11.1 FPS (14.8%) from High to Ultra. The 4K results show that even the most demanding settings stay above 60 FPS, making this combo viable for 4K gaming across the entire preset range.
