Downfall

The Intel Core i5-10400F paired with the AMD Radeon RX 6800 XT delivers a wide performance envelope in Downfall, a horror title from 2016. The measured frame rates show a system that is clearly GPU-limited at higher resolutions but reveals CPU headroom at 1080p. The data indicates that this combination is best suited for high-refresh-rate 1440p gaming, where it maintains excellent average frame rates without pushing the CPU to its limits.

Resolution Scaling

The frame rate progression from 1920x1080 to 3840x2160 reveals a classic GPU-bound scaling pattern. At 1080p with Low settings, the combo produces 286 FPS, which drops to 209.8 FPS at 1440p and further to 131.8 FPS at 4K. This represents a 53.9% reduction in performance from 1080p to 4K at Low settings, indicating that the RX 6800 XT is the primary bottleneck as pixel count increases.

The scaling becomes more pronounced at higher settings. At Ultra, the average FPS falls from 119.0 at 1080p to 86.6 at 1440p (a 27.2% drop) and then to 51.9 at 4K (a 56.4% drop from 1080p). This steeper decline at Ultra settings suggests that the GPU's shading units and memory bandwidth are being saturated by the combination of high resolution and intensive graphical effects.

At Medium settings, the pattern holds: 239.3 FPS at 1080p, 170.1 at 1440p, and 105.1 at 4K. The consistent ~30% performance penalty from 1080p to 1440p across all settings indicates that the CPU is not the limiting factor at these resolutions—the RX 6800 XT's 512.0 GB/s memory bandwidth and 20.74 TFLOPS FP32 throughput are the determining factors. The 4K Ultra result of 51.9 FPS, while playable, shows the steepest degradation, suggesting that this title's Ultra preset includes effects that disproportionately tax the GPU at high pixel counts.

CPU Role

The Intel Core i5-10400F is a 6-core, 12-thread processor based on the Comet Lake architecture, built on Intel's 14 nm process. It has a base clock of 2.90 GHz and a boost clock of 4.30 GHz, with 12 MB of shared L3 cache. The CPU's benchmark results show a clear scaling pattern: 3dmark scores rise from 1350 with 2 threads to 3929 with 8 threads, but only marginally improve to 4735 with max threads. This indicates that the processor's performance gains plateau beyond 8 threads, which is typical for a 6-core design.

In Downfall, a horror game released in 2016, the CPU's role is less critical than in modern titles. The measured FPS at 1080p Low (286 FPS) represents the practical ceiling of this processor in this game—the GPU could likely render more frames, but the CPU's single-thread performance (688 in 3dmark single-thread, 1453 in Cinebench R23 single-core) becomes the bottleneck. The 4.30 GHz boost clock helps maintain high minimum frame rates, though the data does not include min FPS values to confirm this.

The CPU's 73rd percentile ranking among all CPUs, with an average benchmark score of 14168, places it slightly above the AMD EPYC 7552 (14115, +0.4%) and below the AMD Ryzen 3 7320C (14277, -0.8%). This positioning suggests that while the i5-10400F is not a top-tier processor, it provides sufficient compute power for Downfall's requirements. The 12 threads ensure that background processes and game logic do not starve the rendering pipeline, particularly at 1440p where the combo shines.

How This Combo Ranks

The combination of the Intel Core i5-10400F and AMD Radeon RX 6800 XT ranks 585th out of 1741 tested configurations in Downfall, placing it in the 66.4th percentile of all combos. This rank reflects the GPU's strong contribution—the RX 6800 XT sits in the 87th percentile for all GPUs, while the CPU is in the 73rd percentile. The combination leverages the GPU's high performance (49982 average benchmark score) to offset the CPU's more modest standing.

Compared to the GPU's nearest rivals, the RX 6800 XT's average score of 49982 is 0.5% above the Intel Arc A550M (49737) and 2.6% above the NVIDIA GeForce RTX 4070 Ti SUPER (48704). The GPU's 16 GB of VRAM and 4608 shading units provide substantial headroom for Downfall's horror environments, which often feature dynamic lighting and shadow effects. The combo's rank suggests that it outperforms the majority of tested systems, though it does not crack the top third of configurations—likely due to the CPU's mid-range positioning.

The rank of 585 out of 1741 means that approximately 1156 other combos perform better in this specific game. This is consistent with the CPU's 73rd percentile, which suggests that many configurations pair the RX 6800 XT with more powerful processors. However, the measured FPS data indicates that in practice, the combo delivers excellent frame rates at 1440p, suggesting that the rank may underestimate real-world performance in this title's specific workload.

Settings Recommendations

The measured data points to Medium settings at 2560x1440 as the optimal configuration for this combo. At this setting and resolution, the average FPS is 170.1, which is 28.1% higher than High (142.2) and 96.4% higher than Ultra (86.6). The Medium preset provides a significant frame rate boost over High while likely maintaining acceptable visual quality for a horror game where atmosphere matters.

For players prioritizing visual fidelity, High settings at 1440p (142.2 FPS) is the strongest recommendation. This setting delivers frame rates well above the 60 FPS threshold for smooth gameplay, and the 34.1 FPS improvement over Ultra (86.6 FPS) comes at a modest visual cost. At 4K, High settings (86.6 FPS) are playable, but Medium (105.1 FPS) offers a safer margin for maintaining consistent frame rates during intense scenes.

The Low preset is not recommended for this combo, as it leaves significant performance on the table. At 1080p Low, the system produces 286 FPS, which exceeds the refresh rate of most monitors and indicates that the CPU is the limiting factor. The data suggests that the i5-10400F cannot fully utilize the RX 6800 XT's capabilities at low settings and resolutions, making higher settings a better use of the GPU's power.

Measured FPS Breakdown

At 1920x1080, the combo delivers its highest frame rates across all settings. Low settings produce 286 FPS, Medium 239.3 FPS, High 195.8 FPS, and Ultra 119 FPS. The progression from Low to Ultra shows a 58.4% reduction in performance, with each settings tier costing approximately 40-50 FPS. The 1080p results indicate that the CPU is the primary limiter at this resolution, as the GPU could likely render more frames if the processor could feed it faster.

At 2560x1440, the frame rates remain robust: Low 209.8 FPS, Medium 170.1 FPS, High 142.2 FPS, and Ultra 86.6 FPS. The scaling from 1080p to 1440p shows a 26.6% reduction at Low, 28.9% at Medium, 27.4% at High, and 27.2% at Ultra. This consistent ~27% penalty across settings confirms that the GPU is now the bottleneck, as the resolution increase affects all settings proportionally.

At 3840x2160, the frame rates drop significantly: Low 131.8 FPS, Medium 105.1 FPS, High 86.6 FPS, and Ultra 51.9 FPS. The 4K Ultra result is the only measured value below 60 FPS, representing a 56.4% reduction from the 1080p Ultra score. The 4K results show that the RX 6800 XT's 512.0 GB/s memory bandwidth and 288 TMUs are strained by the combination of high resolution and intensive settings, though the card's 128 ROPs ensure that even at 4K High, frame rates remain playable. The data reveals a clear hierarchy: 1080p is CPU-limited, 1440p is balanced, and 4K is GPU-limited.
