A: Yes, the GPU supports DirectX 12 Ultimate (12_2), Vulkan 1.4, and OpenGL 4.6, ensuring full compatibility with Doom’s rendering paths and enabling advanced features.

Q: What is the maximum measured FPS for this combo?

A: The highest recorded average frame rate is 459.5 FPS, achieved at 1920x1080 resolution with Low settings.

Q: Is there a significant performance gap between Ultra and High settings at 4K?

A: Yes, at 3840x2160, dropping from Ultra to High increases the average FPS from 97.9 to 120.1, a gain of 22.2 FPS. This suggests that Ultra settings place a substantial load on the GPU.

Settings Recommendations

For the best balance of visual fidelity and performance, the data points to High settings as the sweet spot. At 3840x2160, High yields an average of 120.1 FPS, which is ideal for smooth 4K gaming on high-refresh-rate displays. While Ultra produces a playable 97.9 FPS, the jump to High provides a meaningful 22.2 FPS uplift with arguably minimal visual difference in a fast-paced game like Doom. The Medium preset offers a middle ground at 139.8 FPS, but High is the recommended choice for those prioritizing a consistently high frame rate without sacrificing too much detail. At lower resolutions, High settings still deliver exceptional results, with 220 FPS at 2560x1440 and 338.1 FPS at 1920x1080, making it a universally strong choice.

Measured FPS Breakdown

Resolution by resolution, the data reveals a clear hierarchy. Starting at 1920x1080, the combo is massively overkill for most displays. Low settings produce an average of 459.5 FPS, Medium hits 399.6 FPS, High reaches 338.1 FPS, and Ultra still achieves 274.4 FPS. At 2560x1440, the frame rates remain extremely high: Low runs at 300.3 FPS, Medium at 261.9 FPS, High at 220 FPS, and Ultra at 179.2 FPS. Moving to 3840x2160, the GPU workload increases significantly. Low settings average 160.6 FPS, Medium drops to 139.8 FPS, High sits at 120.1 FPS, and Ultra falls to 97.9 FPS. The pattern is consistent: each settings tier costs roughly 20-30 FPS, and the gap between Low and Ultra widens as resolution increases. At 1080p, the difference between Low and Ultra is 185.1 FPS, while at 4K, it narrows to 62.7 FPS, indicating a growing GPU bottleneck at higher resolutions.

Resolution Scaling

The frame rate drop from 1080p to 4K highlights the GPU's dominant role in this configuration. At High settings, the average FPS falls from 338.1 at 1920x1080 to 220 at 2560x1440, a 34.9% reduction. Going from 1440p to 4K, the FPS drops further to 120.1, another 45.4% decrease. This scaling is typical of a GPU-bound scenario; as resolution increases, the RTX 5090’s shading units and memory bandwidth become the limiting factor. The CPU’s performance, however, remains nearly constant across resolutions, as its 8 cores and 5.20 GHz boost clock are sufficient to keep up. The data suggests that at 1080p, the combo is so fast that the CPU could become a slight limiting factor, but the 9800X3D’s strong single-core performance minimizes this. The 1.79 TB/s memory bandwidth of the RTX 5090 is a critical asset, ensuring that texture data flows quickly to the GPU cores at all settings.

CPU Role

The Ryzen 7 9800X3D’s architecture is central to its performance in Doom. With 8 cores and 16 threads based on Zen 5 (Granite Ridge) architecture, it provides a solid foundation for gaming. The key feature is the 96 MB of shared L3 cache, which helps keep frequently accessed data close to the cores, reducing latency. Its base clock of 4.70 GHz and boost clock of 5.20 GHz are high for a desktop processor, and the data shows it excels in single-threaded tests, scoring 1212 in 3DMark single-thread and 4430 in Passmark. In multi-threaded workloads, it scores 34004 in Cinebench R23, which is competitive. For Doom, which is not heavily multi-threaded, the single-thread performance is more critical. The CPU’s 90th percentile ranking among all CPUs confirms its status as a top-tier gaming processor. While the RTX 5090 does the heavy lifting in terms of rendering, the 9800X3D ensures the GPU never starves for data, allowing the combo to achieve its high ranks and consistent frame rates across all tested settings.
