Downfall

The Intel Core i5-9400 and NVIDIA GeForce RTX 4080 SUPER pairing produces a notable mismatch in raw compute capability, yet the measured data for Downfall shows the combination delivers exceptionally high frame rates across all tested resolutions. The CPU, a 6-core, 6-thread Coffee Lake part with a 2.90 GHz base and 4.10 GHz boost, ranks in the 47th percentile among all CPUs, while the GPU, an Ada Lovelace architecture part with 16 GB of GDDR6X memory and a 736.3 GB/s bandwidth, sits in the 86th percentile among all GPUs. This analysis explores how these components interact in Downfall, what the recorded data implies about their respective roles, and which settings provide the best experience.

Similar Performance Alternatives

The database places the Intel Core i5-9400 alongside several comparable processors based on average benchmark scores. The nearest rival is the Intel Core i7-1068NG7, which scores 2259 against the i5-9400's 2254, a delta of -0.2 percent, meaning the i7-1068NG7 is effectively identical in performance. The Intel Core i3-10305 scores 2264, a -0.4 percent delta, again nearly indistinguishable. The AMD Ryzen 5 PRO 1500 scores 2246, a 0.4 percent delta, while the Intel Core i7-10710U scores 2248, a 0.3 percent delta. In practical terms, any of these four CPUs would deliver the same level of processing throughput in Downfall, as the differences are within measurement noise. For users considering a platform change, the data suggests the i5-9400's performance class is well represented by these alternatives, none of which would materially alter frame rates in this game.

For the GPU side, the RTX 4080 SUPER's nearest rival is the standard RTX 4080, which scores 54247 against the SUPER's 54209, a -0.1 percent delta. The AMD Radeon Pro W5700X scores 54828, a -1.1 percent delta, while the AMD Radeon RX 6750 GRE 12 GB scores 55698, a -2.7 percent delta, and the AMD Radeon 8060S scores 55757, a -2.8 percent delta. These results indicate that the RTX 4080 SUPER is essentially performance-equivalent to the RTX 4080, and the AMD alternatives, despite slightly higher average scores, fall within a range that would not produce a perceptible difference in Downfall's frame rates. The GPU's percentile ranking at 86 means it outperforms the vast majority of tested graphics cards, but the nearest rivals show that the top end of the GPU spectrum is tightly clustered.

CPU and GPU Roles

Examining the measured FPS across resolutions reveals which component dominates in Downfall. At 1920x1080 with Low settings, the combo achieves 271 FPS. Moving to Medium, the average drops to 252 FPS, then to 235 FPS at High, and 167 FPS at Ultra. The scaling from Low to Ultra at 1080p shows a 104 FPS swing, which suggests the GPU is handling most of the rendering load, but the CPU is not bottlenecking at these high frame rates. At 2560x1440, the pattern continues: Low produces 242 FPS, Medium 225 FPS, High 190 FPS, and Ultra 119 FPS. The drop from Low to Ultra at 1440p is 123 FPS, slightly larger than at 1080p, indicating that the GPU is becoming more stressed as resolution increases, but the CPU still keeps pace.

At 3840x2160, the impact of resolution becomes clearer. Low settings yield 177 FPS, Medium 144 FPS, High 118 FPS, and Ultra 74 FPS. The difference between Low and Ultra at 4K is 103 FPS, similar to the 1080p spread, but the absolute numbers are much lower. The data indicates that the RTX 4080 SUPER is the primary driver of performance, as the frame rate scales predictably with resolution and settings. The i5-9400, with its 47th percentile CPU ranking, does not appear to be a limiting factor in any tested configuration, as even the most demanding 4K Ultra preset still produces 74 FPS. The CPU's role becomes more significant at lower resolutions and higher frame rates, but even at 1080p Low with 271 FPS, the 6-core processor sustains the output without dropping below playable levels.

How This Combo Ranks

The database records this CPU-GPU combination as rank 602 out of 3716 tested combos in Downfall, placing it in the top 16 percent of all configurations. This ranking reflects the GPU's strong performance, as the RTX 4080 SUPER's 86th percentile ranking among GPUs pulls the overall combo upward despite the CPU's more modest 47th percentile standing. The data suggests that in this specific game, the GPU is the dominant factor in determining overall ranking, and the CPU's lower percentile does not drag the combo down significantly. For context, a combo with a similarly ranked CPU but a weaker GPU would likely rank much lower, while a combo with this GPU and a higher-ranked CPU would only marginally improve the rank, as the game appears to be GPU-bound at most settings.

Measured FPS Breakdown

At 1920x1080, the data shows a clear progression across settings. Low settings deliver an average of 271 FPS. Medium settings produce 252 FPS, with a recorded minimum of 214 FPS and a maximum of 290 FPS. High settings yield 235 FPS. Ultra settings drop to 167 FPS. All presets at this resolution remain far above the 60 FPS playable threshold, with even the most demanding Ultra preset showing a substantial margin.

At 2560x1440, the results follow a similar pattern but with lower absolute values. Low settings average 242 FPS. Medium settings average 225 FPS, with a minimum of 191 FPS and a maximum of 259 FPS. High settings produce 190 FPS. Ultra settings average 119 FPS. The gap between Low and Ultra at 1440p is 123 FPS, indicating that the GPU handles the increased resolution well, and the CPU maintains sufficient throughput.

At 3840x2160, the performance remains impressive but shows the expected decline. Low settings average 177 FPS. Medium settings average 144 FPS, with a minimum of 123 FPS and a maximum of 166 FPS. High settings produce 118 FPS. Ultra settings average 74 FPS. Even at the most demanding 4K Ultra preset, the combo stays above the 60 FPS threshold, though the margin narrows compared to lower resolutions.

Best Settings per Resolution

For 1920x1080, the most demanding preset that stays at or above 60 FPS is Ultra, which delivers an average of 167 FPS. This provides a significant cushion above the playable threshold, allowing for maximum visual quality without concern for performance drops. At 2560x1440, Ultra is also the best setting, with an average of 119 FPS, still comfortably above 60 FPS. At 3840x2160, Ultra remains the best playable setting, achieving an average of 74 FPS. This means the combo can run the game at maximum settings at every tested resolution, with the only tradeoff being a reduced frame rate at 4K compared to lower resolutions.

The Verdict

The verdict by resolution is unambiguous: this PC can run Downfall at all tested settings and resolutions. At 3840x2160, all four presets (Low, Medium, High, Ultra) are listed as playable, with Ultra producing the best visual quality at 74 FPS average. At 2560x1440, the same four presets are playable, with Ultra at 119 FPS average, and at 1920x1080, Ultra reaches 167 FPS average. The data indicates that the RTX 4080 SUPER provides more than enough graphics horsepower for this horror game, and the i5-9400, despite its mid-range CPU ranking, does not bottleneck the GPU in any recorded scenario. The only consideration is that 4K Ultra at 74 FPS offers less headroom than the lower resolutions, but it still clears the 60 FPS playable threshold with a 14 FPS margin. For users with a 60 Hz display, this combo delivers a smooth experience at maximum settings across all resolutions. For those with high-refresh displays, the lower resolutions and presets offer frame rates well above 200 FPS, making full use of the GPU's capabilities.
