Doom

The AMD Ryzen 9 9950X3D and AMD Radeon RX 6650 XT represent a pairing of a flagship 16-core processor with a mid-range graphics card. In Doom, the benchmark data reveals a system where the GPU is the primary constraint at higher resolutions, while the CPU’s immense headroom becomes apparent only at 1080p. The measured FPS across settings and resolutions tells a clear story of where the bottleneck lies.

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 from the 9000 series, built on the Zen 5 architecture and codenamed Granite Ridge. Its base clock is 4.30 GHz with a boost clock of 5.70 GHz. This is a desktop-class chip with a 170 W TDP, featuring 128 MB of shared L3 cache. In synthetic benchmarks, its average benchmark score is 71660, placing it in the 96th percentile of all CPUs. The data shows it is 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. Conversely, it trails the Intel Xeon 6517P by 1.9%.

For a game like Doom, which is a fast-paced FPS, the CPU’s job is to handle game logic, physics, and draw calls. The 16 cores and 32 threads are far more than this title can realistically utilize, but the high boost clock of 5.70 GHz is crucial for maintaining high frame rates. The benchmark results indicate that at 1080p, the CPU has ample power. Looking at the measured FPS, at 1920x1080 with Low settings, the system achieves 201.5 FPS. This high figure suggests that the CPU is not limiting performance at this resolution, as the GPU can push frames well past typical refresh rates. However, the 3DMark single-thread score of 1292 and the Cinebench R23 single-core score of 8430 indicate strong per-core performance, which is beneficial for games that rely on a few threads. The data implies that while the CPU is overkill for Doom's core requirements, its high clock speeds ensure it never becomes a bottleneck, especially when paired with a less powerful GPU. The 96th percentile ranking reinforces that this is a top-tier processor, and its role in this specific game is to provide a massive, unutilized safety margin.

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

The measured FPS data shows a clear pattern of how performance scales with resolution. At 1920x1080 with High settings, the average FPS is 148.6. Moving to 2560x1440, the FPS drops to 94.3, which is a 36.5% decrease. Going further to 3840x2160, the FPS falls to 52.5, which is a 44.3% decrease from the 1440p figure and a 64.7% decrease from the 1080p figure. This steep drop-off strongly indicates that the AMD Radeon RX 6650 XT is the limiting component. The GPU’s rendering load increases quadratically with resolution, and its 8 GB of GDDR6 memory and 128-bit bus width struggle to keep up with the pixel count at 4K.

The CPU’s performance is not the issue here. The Ryzen 9 9950X3D’s scores, such as the Cinebench R23 multicore score of 59712, indicate it can handle a massive amount of data.

This indicates the 6650 XT is a solid but not exceptional performer in its class.

In Doom, the GPU’s role is to render the game’s environments and effects. The measured FPS shows that at 1080p, the GPU can deliver high frame rates, with 201.5 FPS on Low and 148.6 FPS on High. However, at 4K, its limitations become apparent. The 8 GB VRAM might be sufficient for Doom, but the GPU's compute power is not enough to maintain high FPS at 3840x2160. The data shows a steady decline in FPS as settings increase at each resolution. For example, at 2560x1440, the FPS ranges from 127.6 on Low to 75.4 on Ultra. This pattern suggests that the GPU is working at its maximum capacity, and the 64 ROPs and 128 TMUs are the limiting factors for pixel and texture throughput. The GPU's 72nd percentile ranking reflects its position as a capable 1080p and 1440p card, but it struggles to maintain playable frame rates at 4K Ultra, where it only achieves 43.3 FPS.

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

The measured FPS data provides a detailed look at performance across three resolutions and four quality presets.

At 1920x1080, the system delivers strong performance. On Low settings, the average FPS is 201.5. Medium settings yield 171.9 FPS. High settings reduce this to 148.6 FPS. The most demanding preset, Ultra, still achieves an average of 119.1 FPS. This resolution is clearly where the combo excels, with all presets well above the 60 FPS threshold for smooth gameplay.

At 2560x1440, performance drops but remains playable. Low settings produce 127.6 FPS, while Medium settings give 115.8 FPS. High settings average 94.3 FPS. Ultra settings drop to 75.4 FPS. All presets at this resolution remain above 60 FPS, indicating a good experience for high-refresh-rate monitors.

At 3840x2160, the GPU becomes the limiting factor. Low settings average 67.9 FPS, which is just above 60 FPS. Medium settings yield 61.2 FPS, also above the threshold. High settings drop to 52.5 FPS, and Ultra settings fall to 43.3 FPS. The data shows that only the Low and Medium presets are playable at 4K, and even then, the frame rates are modest. The drop from 1080p to 4K on Ultra settings is drastic, from 119.1 FPS to 43.3 FPS, a 75.8 FPS difference that highlights the GPU's struggle with 4K resolution.

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

Based on the measured FPS data, the optimal settings depend on the target resolution and desired frame rate. For a 1080p display, the Ultra preset is recommended, as it achieves an average of 119.1 FPS. This provides the best visual quality while maintaining a frame rate that is well above the standard 60 FPS target and suitable for high refresh rate displays. The High preset at 1080p offers 148.6 FPS, which is also excellent, but the visual fidelity increase from Ultra is worth the moderate FPS trade-off.

For 1440p, the High preset is the best choice. It delivers 94.3 FPS, which is smooth and responsive. While the Ultra preset at 1440p achieves 75.4 FPS, the drop in frame rate may not be worth the marginal visual improvements over High. The Medium preset at 1440p provides 115.8 FPS, but the visual quality is noticeably lower. The data suggests that High is the sweet spot for 1440p, balancing visual quality and performance.

For 4K, the options are limited. The Medium preset achieves 61.2 FPS, which is just above the 60 FPS threshold, but the Low preset offers a higher 67.9 FPS. Given the low frame rates, a user would need to prioritize either visual quality or smoothness. The Medium preset at 61.2 FPS is the highest quality option that remains playable, but it is close to the edge. The Low preset at 67.9 FPS provides a more comfortable margin above 60 FPS. For the best experience at 4K, the Low preset is recommended to ensure a stable frame rate, as the visual difference between Low and Medium is less impactful than the FPS difference of 6.7 FPS. Ultimately, the data shows that this combo is best suited for 1080p and 1440p gaming, with 4K requiring significant compromises.
