Doom

The AMD Ryzen 9 9950X3D, as the central processor in this configuration, brings 16 cores and 32 threads, running at a base clock of 4.30 GHz and a boost clock of 5.70 GHz. This Zen 5 architecture part, built on a 4 nm process, is a top-tier desktop component; its multi-threaded benchmark scores are substantial, with a Cinebench R23 multi-core score reaching 59712 and a Geekbench multi-core score of 22515. Its overall average benchmark score is 71660, which places it in the 96th percentile of all CPUs, indicating that the processor is rarely the limiting factor in most gaming workloads. The data shows that this CPU is a high-end part, and in the context of Doom, a game from 2016, it is unlikely to constrain frame rates at any resolution. The benchmark results confirm this, as the CPU’s single-threaded performance, evidenced by a Geekbench single-core score of 3401 and a Cinebench R23 single-core score of 8430, ensures that even the most demanding game logic is handled with ease. The processor’s 128 MB of shared L3 cache is a feature that can benefit game performance, but the measured FPS in this pairing will be dictated by the GPU, not by this processor’s capabilities.

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

The Ryzen 9 9950X3D is a 16-core, 32-thread processor, which is an extreme amount of parallelism for a game like Doom, which was released in 2016 and is known for its scalability on older hardware. In this pairing, the CPU’s role is to provide a stable platform that will not bottleneck the GPU. The processor’s clock speeds, with a 4.30 GHz base and a 5.70 GHz boost, are high, and its benchmark scores reflect that. For instance, the Cinebench R20 single-core score is 3540, and the 3DMark 2-thread score is 2549, which are strong indicators of fast, responsive single-thread performance. When looking at the measured FPS, the fact that the frame rates scale so heavily with resolution and settings suggests that the CPU is not a limiting factor; if the CPU were the bottleneck, the frame rates would be more consistent across resolutions. The processor’s nearest rival, the AMD Ryzen 9 9950X, has an average score of 70420, which is 1.8% lower, showing that the X3D variant is marginally faster in synthetic benchmarks. However, in this game, the CPU’s performance headroom is vast, and the data indicates that the GPU is the component determining the final frame rate output. The high percentile rank of 96 versus all CPUs underscores that this is a top-tier part, and in a title like Doom, its 16 cores and 32 threads are far more than the game can utilize, but they ensure that there are no frame drops due to CPU limitations.

GPU Role — VRAM, clocks, and how they relate to this game's results

The AMD Radeon RX 6600 is the graphics card in this configuration, and it is the primary determinant of the measured FPS. This GPU features 8 GB of GDDR6 memory on a 128-bit bus, with a memory bandwidth of 224.0 GB/s. Its clock speeds are set at a base of 1626 MHz, a game clock of 2044 MHz, and a boost clock of 2491 MHz. The GPU’s compute power is rated at 8.928 TFLOPS for FP32 operations. In the context of Doom, which is a well-optimized title, the RX 6600 is a capable performer, but its 8 GB VRAM and mid-range position in the market are the key factors in the frame rates. The GPU’s average benchmark score is 25235, placing it in the 69th percentile of all GPUs. Its nearest rival, the AMD Radeon RX 6700M, has an average score of 25180, which is 0.2% lower, indicating that the desktop RX 6600 is performing at a level comparable to a mobile chip. The data shows that the GPU is the bottleneck in this system, as the frame rates vary significantly with changes in resolution and settings. The RX 6600’s 8 GB VRAM is sufficient for 1080p and 1440p gaming in Doom, but at 4K with higher settings, the demands on the GPU increase substantially, leading to lower frame rates. The boost clock of 2491 MHz is relatively high, but it cannot compensate for the inherent limitations of the GPU’s memory bus and shading units (1792) when dealing with 4K resolution.

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

The measured FPS data clearly illustrates the scaling of performance with resolution. At 1080p with High settings, the average FPS is 128.1, which drops to 87.0 at 1440p, and then falls to 44.9 at 4K. This pattern is consistent across all settings. For example, at Low settings, the average FPS goes from 175.2 at 1080p, to 115.4 at 1440p, and down to 61.8 at 4K. This significant drop in frame rates as resolution increases is a classic sign of a GPU-bound scenario. The CPU, as previously established, has ample headroom, so the limiting component is the RX 6600. When moving from 1080p to 1440p at High settings, the FPS drops by approximately 32%, and from 1440p to 4K, the FPS drops by approximately 48%. This indicates that the GPU’s rendering workload is increasing exponentially with pixel count. At 1080p, the frame rates are high enough to suggest that the GPU is not fully saturated, but at 4K, the GPU is working at its maximum capacity, resulting in sub-60 FPS averages on most settings. The data shows that the RX 6600 is comfortable at 1080p and capable at 1440p, but 4K is a stretch. The frame rate drop from 1080p to 4K at Ultra settings is particularly steep, going from 106.5 FPS to 34.7 FPS, a reduction of over 67%, which further confirms that the GPU is the primary constraint in this system.

Settings Recommendations — which preset gives the best experience per the measured rows

Based on the measured FPS, the optimal settings depend heavily on the target resolution and desired frame rate. At 1080p, the Ultra preset yields an average of 106.5 FPS, which is well above the 60 FPS threshold for smooth gameplay, and the High preset at 128.1 FPS offers an even better experience with a marginal visual difference. The data shows that at 1080p, the user can comfortably use High settings for a high refresh rate experience, as the 128.1 FPS average is excellent. At 1440p, the High preset delivers 87.0 FPS, which is still a very playable frame rate, while the Ultra preset drops to 65.5 FPS, which is still above 60 FPS but less headroom for demanding scenes. For a more consistent experience at 1440p, High settings appear to be the sweet spot, as they provide a significant FPS boost over Ultra (87.0 vs 65.5) while likely offering a similar visual experience. At 4K, the situation is more constrained. The Low preset achieves an average of 61.8 FPS, which is just barely above 60 FPS, while the Medium preset drops to 52.4 FPS, and High falls to 44.9 FPS. For 4K gaming, the data suggests that Low settings are the only viable option for a smooth experience, as the Medium, High, and Ultra presets all fall below the 60 FPS threshold. The recommendation is to prioritize High settings at 1080p and 1440p for the best balance of visual quality and performance, and to use Low settings at 4K to maintain a playable frame rate.
