Downfall

The AMD Ryzen 5 8400F paired with the AMD Radeon RX 7600 XT delivers a playable experience in Downfall, but the data reveals a system that is heavily constrained by graphics load at higher resolutions. The combination ranks 1115th out of 1741 tested configurations, placing it in the lower-middle tier of the database. This is a pairing where the CPU’s strong multi-threaded compute and the GPU’s substantial 16 GB frame buffer create a distinct performance profile that shifts dramatically depending on the resolution and preset.

Resolution Scaling

The measured FPS data shows a steep and predictable performance decline as resolution increases from 1080p to 4K, but the rate of decline is heavily dependent on the graphics preset. At Low settings, the transition from 1920x1080 to 2560x1440 sees average FPS drop from 201.7 to 140.7, a 30.2% reduction. Moving further to 3840x2160 at Low settings yields 86.9 FPS, which is another 38.2% drop from the 1440p figure. This scaling pattern indicates that even at Low settings, the GPU is becoming the primary bottleneck as pixel count rises, though the CPU still has headroom to push high frame rates at 1080p.

The scaling behavior at High settings is more moderate in percentage terms but still shows the GPU struggling at 4K. At 1920x1080 High, the system achieves 135 FPS. At 2560x1440 High, this falls to 92.6 FPS (a 31.4% drop), and at 3840x2160 High, the average is 60.1 FPS (a 35.1% further drop). The fact that the 1080p to 1440p drop (31.4%) is nearly identical to the 1440p to 4K drop (35.1%) suggests a consistent GPU-bound scaling curve, with the CPU not limiting performance at any of these tested resolutions.

The Ultra preset tells a different story, as it pushes the GPU to its absolute limit. At 1920x1080 Ultra, the system manages 82.7 FPS. At 2560x1440 Ultra, this collapses to 59 FPS (a 28.7% drop), and at 3840x2160 Ultra, it falls to 38.5 FPS (a 34.7% further drop). The 4K Ultra result is the only configuration in the dataset that falls below 60 FPS, indicating that the RX 7600 XT simply does not have enough raw shading power for Downfall at maximum settings and 4K resolution. The data shows that the limiting component at 4K is clearly the GPU, as the CPU’s role diminishes with each resolution step.

CPU Role

The AMD Ryzen 5 8400F is a 6-core, 12-thread processor based on the Zen 4 architecture, built on a 4 nm process at TSMC. Its base clock is 4.20 GHz and it boosts to 4.70 GHz, with a 65 W TDP. In synthetic benchmarks, this CPU shows strong multi-threaded capability, scoring 20,851 in Cinebench R23 multi-core and 2,943 in single-core. Its 3DMark scores scale from 1,874 in the 2-thread test to 6,165 in the max-threads test, indicating good thread scaling across its 12 threads.

In Downfall, a horror title from 2016, the CPU’s role is largely to feed the GPU with draw calls and game logic. The benchmark results show that at 1080p Low, the system reaches 201.7 FPS, which is the highest score in the entire dataset. This high frame rate at a CPU-friendly resolution suggests that the Ryzen 5 8400F is not a bottleneck in this title, even at lower graphics settings where the GPU workload is light. The 16 MB of shared L3 cache and dual-channel DDR5 memory support (with 83.2 GB/s bandwidth) are sufficient for the game’s demands.

The CPU’s percentile ranking of 82nd among all processors, with an average benchmark score of 25,064, places it in a competitive position. Its nearest rivals include the AMD Ryzen 7 2700X (deltaPct 0) and the AMD Ryzen 5 7500F (deltaPct 0.3), indicating that the 8400F is within a fraction of a percent of these parts in average synthetic scores. In the context of Downfall, the CPU’s 6 cores and 12 threads are more than adequate, as evidenced by the fact that even at 1080p High (135 FPS), the system does not appear CPU-limited. The data implies that the CPU is not the limiting component in any of the measured configurations; instead, the GPU takes over that role as resolution and settings increase.

GPU Role

The AMD Radeon RX 7600 XT is the dominant factor in this pairing’s Downfall performance. This GPU is based on the RDNA 3.0 architecture and the Navi 33 chip, built on a 6 nm process at TSMC. It features 16 GB of GDDR6 memory on a 128-bit bus, providing 288.0 GB/s of bandwidth. The GPU’s clocks are listed with a base of 1980 MHz, a game clock of 2470 MHz, and a boost of 2755 MHz, with memory running at 2250 MHz (18 Gbps effective). Its 2048 shading units, 128 TMUs, and 64 ROPs deliver a pixel rate of 176.3 GPixel/s and a texture rate of 352.6 GTexel/s.

The GPU’s synthetic benchmark scores show it is a mid-range part, with a percentile ranking of 63rd among all GPUs and an average benchmark score of 20,146. Its nearest rivals include the AMD Radeon RX 7600 (deltaPct -0.6) and the NVIDIA GeForce RTX 2060 SUPER (deltaPct 1.9), indicating that the RX 7600 XT is positioned just above the RX 7600 and slightly below the RTX 3070 Mobile in raw compute. In Downfall, the 16 GB VRAM capacity is a key feature, though the game’s 2016 release date and horror genre likely do not require more than 8 GB even at 4K Ultra. The data shows the GPU’s 22.57 TFLOPS of FP32 performance is the primary driver of frame rates.

The GPU’s role is most evident in the scaling from Medium to Ultra settings. At 1080p, the jump from Low (201.7 FPS) to Medium (163.9 FPS) to High (135 FPS) to Ultra (82.7 FPS) shows a consistent reduction in performance as the GPU workload increases. The Ultra preset at 4K (38.5 FPS) is the only point where the GPU is completely overwhelmed, suggesting that the RX 7600 XT’s 64 ROPs and 128-bit memory bus are insufficient for the game’s highest settings at 3840x2160. The GPU’s 190 W TDP and dual-slot design are consistent with its performance class, and the data indicates that for most resolutions and settings, this GPU is the limiting component, not the CPU.

Settings Recommendations

The measured FPS data provides clear guidance on which settings preset offers the best experience for this hardware combination. At 1920x1080, all presets are playable, with even Ultra achieving 82.7 FPS. However, the most balanced experience at 1080p is the High preset, which delivers 135 FPS. This is more than sufficient for smooth gameplay and leaves headroom for occasional frame drops that are common in horror titles. The Medium preset at 163.9 FPS offers even more margin, but the visual fidelity loss from High to Medium may not be worth the extra 28.9 FPS for most players.

At 2560x1440, the High preset is the clear recommendation, delivering 92.6 FPS. This is comfortably above the 60 FPS threshold and provides a good balance of visual quality and performance. The Medium preset at 115.1 FPS is also viable for players who prioritize frame rate, while the Ultra preset at 59 FPS is borderline — it is technically playable but leaves no room for frame time spikes. The Low preset at 140.7 FPS is unnecessarily fast and would compromise the game’s horror atmosphere with reduced visual detail.

At 3840x2160, the recommendation narrows significantly. The High preset at 60.1 FPS is the only 4K option that consistently hits the 60 FPS mark, making it the best choice for 4K displays. The Medium preset at 71.5 FPS offers a small performance buffer, but High provides better visual quality at nearly the same frame rate. The Low preset at 86.9 FPS is playable but sacrifices too much visual fidelity for a horror game where atmosphere matters. The Ultra preset at 38.5 FPS is not recommended, as the frame rate is too low for a responsive experience. For this pairing, the data shows that High settings at 1440p or 4K, or Medium at 1080p, provide the best overall experience.
