Downfall

The AMD Ryzen 5 8400F paired with the AMD Radeon RX 5700 XT delivers a playable experience in Downfall, but the data clearly shows that the graphics card is the primary limiting factor as resolution increases. The measured frames per second (FPS) at 1080p are exceptionally high, but the system struggles to maintain high frame rates at 4K, particularly when the settings are pushed to their maximum. This combination is best suited for high-refresh-rate 1080p gaming and can handle 1440p with adjustments, but it is not a 4K powerhouse.

Resolution Scaling

The performance drop from 1080p to 4K is steep and reveals a classic GPU-bound scenario. At 1080p with High settings, the combo produces an average of 125.8 FPS. Moving to 1440p at the same settings, the average drops to 88.1 FPS, and at 4K, it falls to 54.3 FPS. This represents a 56.8% reduction in frame rate from 1080p to 4K, which is a substantial hit that points directly to the Radeon RX 5700 XT's rendering limits rather than any bottleneck from the Ryzen 5 8400F.

The trend is consistent across all settings. At Low settings, the system achieves 185.8 FPS at 1080p, 138 FPS at 1440p, and 84.4 FPS at 4K. Even at the lowest settings, the 4K performance is less than half of what is seen at 1080p. This indicates that the GPU's pixel-pushing capabilities are saturated at higher resolutions, and the CPU's 6 cores and 12 threads have ample headroom to keep up. The CPU’s benchmark scores, such as a Cinebench R23 multi-core score of 20851, suggest it is not the bottleneck in this scenario.

The scaling from 1440p to 4K is particularly punishing. At Medium settings, the frame rate goes from 109.8 FPS at 1440p to 68.3 FPS at 4K, a 37.8% drop. At Ultra settings, the system only manages 54.5 FPS at 1440p and 36.4 FPS at 4K. The data suggests that 4K gaming with this combo is only viable at Low settings, while 1440p is a more reasonable target for higher quality presets. The frame rate scaling here is consistent with a GPU that has a 256-bit memory bus and 8 GB of GDDR6 memory, which is sufficient for 1080p and 1440p but is overwhelmed by the pixel count at 4K.

GPU Role

The AMD Radeon RX 5700 XT is the defining component in this system's gaming performance. It features a Navi 10 chip with a base clock of 1605 MHz and a boost clock of 1905 MHz. The 8 GB of GDDR6 memory operates at an effective speed of 14 Gbps across a 256-bit bus, providing a memory bandwidth of 448.0 GB/s. These specifications are directly reflected in the measured FPS, as the card's performance scales predictably with resolution and settings.

The GPU's role is most evident in the difference between Low and Ultra settings at each resolution. At 1080p, the gap between Low and Ultra is 107.3 FPS (185.8 vs 78.5), which shows the card's raw compute power is sufficient for low-detail work but is heavily taxed by higher graphical fidelity. The 9.754 TFLOPS of FP32 performance and 64 ROPs are put to the test with Ultra settings, which often include more complex lighting and shadow effects. The data shows that the card is most efficient at lower settings where its texture rate of 304.8 GTexel/s can be fully utilized without hitting other bottlenecks.

The GPU’s performance percentile of 68 and its average benchmark score of 24731 place it in the mid-range tier, which aligns with the observed FPS. When compared to its nearest rivals, the RX 5700 XT is essentially on par with the NVIDIA RTX A5000 Mobile, which has a 0.1% higher score, and the Intel Arc A350M, which is 0.3% slower. This indicates that the card’s performance characteristics are well-understood and that the measured results in Downfall are in line with its overall capabilities. The 8 GB VRAM is adequate for the tested presets, but it is a factor that could limit performance in other, more demanding titles.

Settings Recommendations

Based on the measured FPS data, the optimal settings depend on the user's resolution and frame rate preferences. For a 1080p display, the High preset is the recommended choice. It provides an average of 125.8 FPS, which is well above the 60 FPS threshold and smooth enough for most monitors. The Ultra preset also works at 1080p, with 78.5 FPS, but the visual gains may not justify the 37.6% performance drop from High.

For 1440p, the Medium preset offers the best balance of visual quality and performance, with an average of 109.8 FPS. The High preset is also viable, with 88.1 FPS, but users with 144Hz monitors may prefer the higher frame rate of Medium. The Ultra preset at 1440p is not recommended, as the 54.5 FPS average could lead to inconsistent frame pacing and a less enjoyable experience.

For 4K gaming, the Low preset is the only sensible option, yielding 84.4 FPS. The Medium preset at 68.3 FPS is playable, but the High preset at 54.3 FPS and Ultra at 36.4 FPS are too demanding for this GPU. The data shows that this system is not designed for 4K gaming with high settings, and users should stick to lower resolutions to get the most out of the hardware.
