Doom

How This Combo Ranks

Within the tested database for Doom, this pairing of the AMD Ryzen 5 8400F and NVIDIA GeForce RTX 3080 Ti secures the 420th position out of 1681 recorded combinations. This places the system comfortably in the top quartile of all tested configurations, indicating a strong overall capability for this title. The data shows that while this is not an absolute top-tier setup, it sits well above the median performer, delivering a high-refresh-rate experience that many other combinations cannot match.

The ranking is a product of the balance between the two components. The RTX 3080 Ti sits in the 83rd percentile among all GPUs, a figure that places it within striking distance of much newer and more expensive hardware. Its average benchmark score of 41224 is only marginally behind the NVIDIA GeForce RTX 3090, which posts a score of 41441, a negligible 0.5% difference. Similarly, it trails the RTX 5070 by a mere 1.1% in average score (41687), suggesting that the 3080 Ti remains a formidable graphics processor in this context.

On the processor side, the Ryzen 5 8400F holds the 82nd percentile among all CPUs. Its average benchmark score of 25064 is virtually identical to that of the AMD Ryzen 7 2700X (25057) and the AMD Ryzen AI 5 PRO 340 (25099). This indicates that the CPU's compute performance is a known quantity, providing a stable foundation that does not bottleneck the GPU in this specific workload. The combination's overall rank is thus a direct reflection of the GPU's high placement and the CPU's solid, if not spectacular, standing.

Settings Recommendations

The measured data for Doom suggests that the Ultra preset, while visually demanding, is not the optimal choice for this hardware if the goal is a consistently smooth experience. Across all resolutions, the frame rate at Ultra is the lowest among the four settings tested. At 1080p, the Ultra preset delivers 187 FPS, which is certainly playable but represents a significant drop from the other presets. The data indicates that the High preset offers a more balanced trade-off.

At 1440p, the High preset achieves 148.2 FPS, a figure that is well above the threshold for high-refresh-rate monitors and only 26.4% lower than the Low preset's 201.9 FPS. The difference between High and Medium at this resolution is also notable, with High being 21.2% faster than Medium's 179.6 FPS. For 4K gaming, the High preset's 83.5 FPS is the only setting that provides a frame rate comfortably above 60 FPS, making it the clear recommendation for a smooth 4K experience.

The benchmark results indicate that the High preset is the sweet spot for this combination. It provides a substantial visual uplift over Low and Medium while maintaining frame rates that are only modestly lower than the performance-oriented presets. Choosing High over Ultra yields a performance increase of 23.5% at 1080p (from 187 to 231.1 FPS), 21.7% at 1440p (from 121.8 to 148.2 FPS), and 23.3% at 4K (from 67.7 to 83.5 FPS). This consistent performance headroom makes High the most sensible default setting for this system.

Resolution Scaling

The data reveals a predictable and clear scaling pattern as resolution increases, highlighting the growing burden on the GPU. Moving from 1080p to 1440p at High settings, the average frame rate drops from 231.1 FPS to 148.2 FPS, a 35.9% reduction. The subsequent step to 4K results in a further decline to 83.5 FPS, which is a 43.7% drop from the 1440p figure. This pattern is consistent across all settings presets, confirming that resolution is the primary factor influencing performance.

This scaling behavior strongly indicates that the system becomes increasingly GPU-limited at higher resolutions. The CPU's role is more pronounced at 1080p, where the frame rates are exceptionally high (314.1 FPS at Low), suggesting that the processor is working harder to feed the GPU. However, as resolution climbs, the GPU's rendering workload expands, and the frame rate becomes more dependent on the graphics card's raw throughput. The gap between the Low and Ultra presets also narrows slightly at higher resolutions, further emphasizing the GPU's dominance in the rendering pipeline.

The frame rate deltas between presets are relatively consistent across resolutions, which points to a well-balanced system. The CPU has enough headroom to handle the lower-resolution, high-frame-rate scenarios, while the GPU has enough power to maintain respectable performance at 4K. The data suggests that the limiting component shifts from the CPU at 1080p to the GPU at 4K, but neither component becomes a severe bottleneck at any tested configuration.

Measured FPS Breakdown

The complete set of measured data paints a detailed picture of performance. At 1920x1080, the system is exceptionally fast, with the Low preset leading at 314.1 FPS. Medium follows at 275.2 FPS, High at 231.1 FPS, and Ultra trails at 187 FPS. These numbers indicate that even at the highest settings, the system can easily drive a 144Hz or 165Hz monitor, and at lower presets, it can push well beyond 240Hz.

Moving to 2560x1440, the performance remains high. The Low preset achieves 201.9 FPS, while Medium and High post 179.6 FPS and 148.2 FPS, respectively. The Ultra preset falls to 121.8 FPS. This resolution represents a strong balance for this hardware, as all presets are capable of delivering a high-refresh-rate experience, with only the Ultra preset dipping below the 144 FPS threshold.

At 3840x2160, the system's limits become apparent. The Low preset is the only one to break the 100 FPS barrier, delivering 111.7 FPS. Medium follows at 96.6 FPS, and High manages a solid 83.5 FPS. The Ultra preset falls to 67.7 FPS, which is still playable but is the only configuration that approaches the lower boundary of a smooth high-refresh experience. The data shows a clear hierarchy of performance, with every step up in resolution and quality having a predictable impact on the average frame rate.

GPU Role

The NVIDIA GeForce RTX 3080 Ti is the dominant force in this pairing. Its 12 GB of GDDR6X memory on a 384-bit bus provides a substantial 912.4 GB/s of bandwidth, which is critical for feeding the GPU's 10240 shading units at high resolutions. The memory clock operates at 1188 MHz, translating to 19 Gbps effective, while the GPU core has a base clock of 1365 MHz and a boost clock of 1665 MHz.

These specifications directly support the observed performance. The high memory bandwidth ensures that texture data is readily available, preventing stalls in demanding scenes. The large number of shading units provides the raw compute power needed for the high frame rates seen at 1080p and 1440p. The GPU's benchmark percentile of 83 and its close scores to the RTX 3090 and RTX 5070 confirm that its architecture remains highly effective for this game, despite being from the previous generation.

The data shows that the GPU's capabilities are the primary reason for the strong 4K performance. The ability to maintain an average of 83.5 FPS at 4K High settings confirms its memory bandwidth and compute throughput. The GPU's role becomes increasingly critical as resolution rises, and its performance scaling in this game is a clear indicator of its strength.

CPU Role

The AMD Ryzen 5 8400F provides the computational foundation for this system. With 6 cores and 12 threads based on the Zen 4 architecture, it offers a balanced mix of single-thread and multi-thread performance. Its base clock of 4.20 GHz and boost clock of 4.70 GHz are key to its ability to keep up with the high frame rates produced by the GPU.

The CPU's benchmark results show a single-thread score of 951 in 3dmark and 3684 in PassMark, indicating strong per-core performance. This is crucial for a game like Doom, which often relies on a few primary threads. The multi-threaded scores are also respectable, with a Cinebench R23 multi-core score of 20851, ensuring that background tasks and secondary game threads are handled efficiently.

The data suggests that the CPU is not the limiting factor in this configuration. At 1080p Low, the system reaches 314.1 FPS, which is a demanding scenario for a processor. The fact that it can achieve this level of performance indicates that the Ryzen 5 8400F has sufficient headroom to feed the RTX 3080 Ti. The CPU's 82nd percentile ranking and its close performance to other processors like the Ryzen 7 2700X confirm that it is a capable partner, allowing the GPU to operate at its full potential across all tested resolutions and settings.
