Doom

The AMD Ryzen 7 5800X3D is an 8-core, 16-thread processor based on the Zen 3 architecture, with a base clock of 3.40 GHz and a boost clock of 4.50 GHz. Its defining feature is the large 96 MB shared L3 cache, which is crucial for gaming performance. In the context of Doom, this processor’s multi-threaded capabilities are substantial; its 3DMark max-thread score of 7285 indicates that it can handle the game’s engine threads without becoming a bottleneck. The processor’s single-thread performance, measured at 884 in 3DMark single-thread and 3234 in Passmark single-thread, is robust for a chip from this generation. When looking at the measured frame rates, the data shows that the CPU is not the limiting factor at lower resolutions. At 1080p with Low settings, the system achieves 340 FPS, a figure that relies heavily on the CPU’s ability to feed the GPU with draw calls. The 5800X3D’s 16 threads allow it to maintain high minimum frame pacing, ensuring that the fast-paced action in Doom remains fluid. The processor’s performance is comparable to its nearest rivals; for instance, it sits just 0.1% ahead of the Intel Core i9-11900K and 0.2% behind the AMD Ryzen 5 7600 in average benchmark score. This parity suggests that the CPU’s cache advantage is balanced by the higher clock speeds of other chips, but in Doom’s specific workload, the data confirms the 5800X3D is more than sufficient to push high frame rates. The processor’s Passmark multi-thread score of 28309 further reinforces that it has ample headroom for this title, which was released in 2016 and is not heavily threaded by modern standards.

GPU Role

The NVIDIA GeForce RTX 5070 is the primary driver of visual fidelity in this configuration. It features 12 GB of GDDR7 memory on a 192-bit bus, delivering a memory bandwidth of 672.0 GB/s. The GPU’s base clock is 2325 MHz with a boost clock of 2512 MHz, and its memory operates at an effective speed of 28 Gbps. In Doom, the GPU’s role becomes increasingly dominant as resolution and settings scale up. The data shows a clear progression: at 1080p Low, the GPU produces 340 FPS, but this drops to 203.2 FPS at 1080p Ultra, a reduction driven by the increased shading load. The RTX 5070’s shading units and texture units handle the game’s lighting and texture filtering efficiently, but the most telling metric is the Passmark G3D score of 29137, which places it in the 83rd percentile among all GPUs. Compared to its nearest rivals, the RTX 5070 is 0.6% ahead of the NVIDIA GeForce RTX 3090 in average benchmark score, yet 0.5% behind the NVIDIA Tesla M40. This indicates that while the card is powerful, it is not an outlier in raw compute; instead, its modern architecture and high memory bandwidth allow it to excel in real-world gaming scenarios. In Doom, the GPU’s VRAM capacity of 12 GB is never stressed, even at 4K Ultra, which allows the card to focus on compute and rasterization tasks. The measured FPS at 4K Ultra is 72.8, which is playable, but the data suggests that the GPU is the primary constraint at this setting, as reducing settings yields significant gains.

Resolution Scaling

The measured frame rates across resolutions reveal the classic scaling pattern of a system where the GPU becomes the bottleneck as pixel count increases. At 1080p High, the system delivers 251.9 FPS, but moving to 1440p High reduces this to 163.6 FPS, a drop of 35%. Further scaling to 4K High results in 84.6 FPS, a 66% reduction from 1080p. This steep decline indicates that the RTX 5070 is the limiting component at higher resolutions, while the Ryzen 7 5800X3D has sufficient headroom to keep up. The data shows a similar trend for Ultra settings: 203.2 FPS at 1080p, 134.8 FPS at 1440p, and 72.8 FPS at 4K. The drop from 1080p to 1440p Ultra is 34%, and from 1440p to 4K Ultra is 46%. This non-linear decline is typical of GPU-bound scenarios, where the increased pixel count demands more from the memory bus and shader units. Conversely, at Low settings, the scaling is less severe: 340 FPS at 1080p, 217.1 FPS at 1440p, and 121.6 FPS at 4K. The 4K Low result is still far above the 60 FPS threshold, indicating that even at this high resolution, the CPU is not a limiting factor. The benchmark results suggest that for competitive play, 1080p offers the highest frame rates, but for a balanced experience, 1440p provides a good compromise between visual quality and speed. The 4K results, while lower, remain playable at all settings, with the Low preset offering more than double the frame rate of Ultra.

Settings Recommendations

The measured rows provide clear guidance on which preset offers the best experience for this combination of CPU and GPU. At 1080p, the High preset delivers 251.9 FPS, which is only slightly lower than the Low preset’s 340 FPS but with significantly better visual quality. The Ultra preset at 1080p drops to 203.2 FPS, still a very high number, but the performance cost of moving from High to Ultra is a 19% reduction in frame rate for what is often a marginal visual improvement in Doom. At 1440p, the High preset again stands out, with 163.6 FPS, which is more than sufficient for high-refresh-rate monitors. The Medium preset at 1440p yields 188.7 FPS, a 15% improvement over High, but the visual difference is noticeable in texture quality and shadow fidelity. For the best balance of smoothness and visual fidelity, the High preset at 1440p is the recommended choice, as it stays well above 144 FPS while maintaining detailed environments. At 4K, the Ultra preset drops to 72.8 FPS, which is playable but not ideal for fast-paced action. The High preset at 4K provides 84.6 FPS, a 16% improvement over Ultra, and is the better option for a stable experience. The data indicates that the Low preset at 4K, with 121.6 FPS, is only recommended for players who prioritize frame rate above all else, as the visual downgrade is substantial. Across all resolutions, the High preset offers the best performance-per-visual-quality ratio, as it consistently delivers frame rates that are 20-30% higher than Ultra while maintaining a high level of detail.
