Downfall

Settings Recommendations

The measured frame rates for this combination show a clear hierarchy across presets, but the optimal choice depends heavily on the target resolution. At 1920x1080, the Ultra preset delivers 128.8 FPS average, which is more than sufficient for smooth gameplay in a horror title where responsiveness matters less than atmosphere. The Medium preset at 255.2 FPS and High at 208.1 FPS both represent diminishing returns for a genre that rarely benefits from triple-digit refresh rates beyond a certain point. For 1080p, the High preset at 208.1 FPS offers the best balance between visual fidelity and performance headroom.

At 2560x1440, the High preset achieves 151.7 FPS, while Ultra drops to 93.1 FPS. The gap between High and Ultra here is substantial — a 58.6 FPS difference that translates to a roughly 63% performance penalty for the highest preset. Given that horror games rely heavily on lighting and shadow quality, the High preset retains enough visual detail to maintain immersion while keeping frame rates in a comfortable range. The Medium preset at 179.3 FPS is also viable, but the visual step down from High is more noticeable at this resolution.

At 3840x2160, the situation changes dramatically. Ultra falls to 55.9 FPS, which is below the 60 FPS threshold that most players consider acceptable for smooth motion. High at 94.7 FPS is the clear recommendation at 4K, offering a 38.8 FPS advantage over Ultra while still maintaining the higher-quality textures and effects that matter in a horror setting. The Medium preset at 112.5 FPS is a reasonable alternative for those prioritizing frame rate, but High provides the best experiential balance. Low presets across all resolutions — 267.8 FPS at 1080p, 223.1 FPS at 1440p, and 140.3 FPS at 4K — are not recommended since the visual degradation in a horror title undermines the atmospheric tension that defines the genre.

GPU Role

The AMD Radeon RX 9070 XT brings substantial graphics resources to this pairing. Its 16 GB of GDDR6 memory on a 256-bit bus delivers 644.6 GB/s of bandwidth, which proves critical for Downfall's texture-heavy environments. The GPU's boost clock reaches 2970 MHz, with a game clock of 2400 MHz, and these frequencies directly influence the measured frame rates. The card's 4096 shading units and 128 ROPs handle the game's rendering workload efficiently, as evidenced by the strong performance at 4K High.

The GPU holds the 82nd percentile among all tested GPUs, with an average benchmark score of 39647. Its nearest rivals in general benchmarks include the AMD Radeon Pro 575 at 39703 (a -0.1% delta) and the NVIDIA RTX A500 Mobile at 39568 (a 0.2% delta). However, the RX 9070 XT's real-world performance in Downfall demonstrates that general benchmark scores do not always translate linearly to specific game performance. The card's 3DMark Steel Nomad DX12 score of 7260 and Geekbench Vulkan score of 184026 indicate strong modern API support, which aligns with the game's measured frame rates.

The GPU's memory configuration is particularly relevant at 3840x2160, where the 16 GB capacity prevents any resolution-related memory pressure. The 644.6 GB/s bandwidth ensures that texture streaming at Ultra settings does not become a bottleneck. The card's RDNA 4.0 architecture with 64 RT cores suggests hardware-level ray tracing capability, though the measured data does not isolate ray tracing effects. The pixel rate of 380.2 GPixel/s and texture rate of 760.3 GTexel/s provide the raw throughput needed for the game's high-resolution rendering, as reflected in the 94.7 FPS average at 4K High.

Resolution Scaling

The resolution scaling pattern reveals a system that transitions from CPU-bound at lower resolutions to GPU-bound at higher ones. At 1920x1080, the Low preset delivers 267.8 FPS, while the Ultra preset drops to 128.8 FPS — a 139 FPS spread that indicates the GPU is doing meaningful work even at 1080p. However, the fact that Low at 1080p reaches nearly 268 FPS suggests the Intel Core i5-9400 is capable of feeding the RX 9070 XT at high frame rates without becoming a limiting factor.

Moving to 2560x1440, the frame rates scale predictably. Low drops to 223.1 FPS (a 44.7 FPS decrease from 1080p), High drops to 151.7 FPS (a 56.4 FPS decrease), and Ultra drops to 93.1 FPS (a 35.7 FPS decrease). The proportional reductions are consistent with a GPU that has ample headroom at 1440p. The fact that even Ultra at 1440p maintains 93.1 FPS indicates that the combination is not severely bottlenecked at this resolution.

At 3840x2160, the scaling becomes more dramatic. Low falls to 140.3 FPS (a 127.5 FPS drop from 1080p), while Ultra falls to 55.9 FPS (a 72.9 FPS drop). The High preset at 4K achieves 94.7 FPS, which is 113.4 FPS lower than the 1080p High result. This steep decline at 4K, particularly for the Low preset, suggests that the GPU's fill rate and memory bandwidth become the dominant constraints at this resolution. The 16 GB frame buffer prevents capacity issues, but the pixel throughput requirements at 3840x2160 — roughly 2.25 times the pixel count of 1440p — directly impact the measured frame rates. The data shows that the i5-9400 remains sufficient even at 4K, as the GPU-side rendering workload dominates the performance equation.

FAQ

Q: What is the best preset for 1440p gaming with this combination?

A: The High preset at 2560x1440 delivers 151.7 FPS, which provides smooth gameplay while maintaining visual quality. Ultra drops to 93.1 FPS, a 58.6 FPS penalty that may not justify the additional visual fidelity in a horror title.

Q: How does this combo rank among all tested combinations in Downfall?

A: This configuration ranks 500th out of 1741 tested combinations, placing it in the upper portion of the database. The data indicates the combination is well-positioned for this game's performance demands.

How This Combo Ranks

The combination of the Intel Core i5-9400 and AMD Radeon RX 9070 XT ranks 500th out of 1741 tested combos in Downfall, placing it in the 71st percentile of all configurations. This ranking reflects a strong overall performance profile, though not an elite one. The CPU's contribution to this ranking is moderate — the i5-9400 sits at the 50th percentile among all CPUs, with an average benchmark score of 2305. Its nearest rivals include the Intel Core i3-10305 at 2300 (0.2% delta) and the Intel Core i3-1125G4 at 2299 (0.2% delta), while the Intel Core i7-8809G at 2319 shows a -0.6% delta. This places the CPU in a tight cluster of mid-range processors.

The GPU's percentile ranking of 82nd among all GPUs, with an average benchmark score of 39647, indicates that the RX 9070 XT is the primary driver of this combo's 500th-place finish. The GPU's nearest rivals in general benchmarks — the Radeon Pro 575, RTX A500 Mobile, Radeon Pro 575X, and RX Vega 64 — all score within 0.6% of each other, yet the RX 9070 XT's in-game performance at 4K High (94.7 FPS) and 1440p High (151.7 FPS) suggests its real-world capabilities extend beyond what synthetic averages capture.

The ranking of 500 out of 1741 means that 1241 tested combinations perform worse in Downfall, while 499 perform better. This places the combo in the upper third of all configurations, which is notable given the CPU's mid-range standing. The data indicates that the GPU's substantial resources compensate for the CPU's modest benchmark scores, particularly at higher resolutions where the rendering workload dominates. At 1080p, the CPU's 6 cores and 6 threads with a 4.10 GHz boost clock are sufficient to avoid bottlenecking the GPU, as evidenced by the 208.1 FPS at High settings.

The ranking also contextualizes the preset recommendations. A combo ranked 500th overall can afford to run High settings at 4K (94.7 FPS) and Ultra at 1440p (93.1 FPS), but Ultra at 4K (55.9 FPS) pushes beyond what this configuration can comfortably sustain. The performance headroom at lower resolutions — 267.8 FPS at 1080p Low — confirms that this pairing is well-suited for high-refresh-rate monitors at 1080p, while remaining viable for 4K with appropriate settings adjustments. The combination's position in the database reflects a balanced pairing where the GPU carries the high-resolution workload and the CPU provides adequate support without becoming a significant liability.
