Downfall

Resolution Scaling

The measured frame rates across resolutions reveal a system that scales predictably with pixel count, though the rate of decline steepens significantly at the highest settings. At 1080p with Low settings, the combo produces 312.8 FPS. Moving to 1440p drops this to 222.7 FPS, a 28.8% reduction. At 4K, the same Low preset yields 137.6 FPS, which is 56% below the 1080p figure. This scaling pattern indicates that the GPU is the primary limiter as resolution climbs, since the CPU has ample headroom at lower pixel counts.

The High preset tells a similar story with slightly smaller absolute numbers. At 1080p High, the system delivers 212 FPS. At 1440p High, it falls to 153.2 FPS, a 27.7% decline. At 4K High, the average is 96 FPS, which is 54.7% lower than the 1080p result. The consistency of these percentage drops across presets suggests that the rendering workload scales almost linearly with resolution, which is typical for a horror title with heavy ambient occlusion and shadow effects.

Ultra settings amplify the resolution sensitivity. The 1080p Ultra result of 132.7 FPS drops to 93.1 FPS at 1440p, a 29.8% reduction. At 4K Ultra, the average plunges to 60.9 FPS, which is 54.1% below the 1080p Ultra figure. This near-uniform ~55% drop from 1080p to 4K across all presets strongly indicates that the limiting component is the GPU's fill rate and memory bandwidth, not the CPU. The RTX 4070's 504.2 GB/s bandwidth and 158.4 GPixel/s pixel rate are being fully utilized at higher resolutions, while the Ryzen 9 7900X's 12 cores remain underutilized.

The gap between Low and Ultra at each resolution widens as resolution decreases. At 1080p, the spread between Low (312.8 FPS) and Ultra (132.7 FPS) is 180.1 FPS. At 1440p, the spread narrows to 129.6 FPS. At 4K, it tightens to 76.7 FPS. This compression at higher resolutions is a classic sign of GPU-bound behavior, where even the lowest settings cannot fully escape the pixel throughput ceiling.

GPU Role

The NVIDIA GeForce RTX 4070, built on the Ada Lovelace architecture with a 5 nm process, carries 12 GB of GDDR6X memory on a 192-bit bus. Its base clock of 1920 MHz boosts to 2475 MHz, and the memory runs at 1313 MHz with 21 Gbps effective speed. The 5888 shading units and 64 ROPs deliver a measured FP32 throughput of 29.15 TFLOPS. These specifications position the card at the 81st percentile among all GPUs in the database.

The GPU's benchmark results provide context for the game performance. Its PassMark G3D score of 26927 and average benchmark score of 37283 place it within a narrow band of rivals. The nearest competitor, AMD Radeon RX Vega 56, scores 37507, just 0.6% higher. The NVIDIA GeForce MX570 A and RTX 4080 Mobile score 38008 and 38135 respectively, representing 1.9% and 2.2% deltas. The AMD Radeon RX 5300M trails at 36371, which is 2.5% lower. This tight clustering suggests the RTX 4070 desktop card performs comparably to these mobile and older parts in synthetic workloads, but the game data shows it handles Downfall's specific rendering demands well.

The 12 GB VRAM capacity is sufficient for Downfall's horror environments, which often feature dense fog, volumetric lighting, and high-resolution textures. At 4K Ultra, the game still maintains 60.9 FPS, indicating the memory footprint does not exceed the 12 GB allocation. The 192-bit bus and 504.2 GB/s bandwidth become the limiting factor at 4K, as evidenced by the steep FPS decline from 1080p to 4K across all presets. The GPU's 200 W TDP and 550 W suggested PSU are consistent with its mid-range positioning, though these figures are not directly reflected in the game performance data.

CPU Role

The AMD Ryzen 9 7900X is a 12-core, 24-thread processor from the 7000 series, based on Zen 4 architecture (codenamed Raphael). It operates on the AMD Socket AM5 platform with a base clock of 4.70 GHz and boost clock of 5.60 GHz. The processor has a 64 MB shared L3 cache, with 1 MB L2 per core and 64 KB L1 per core. It supports DDR5 memory in dual-channel configuration, providing 83.2 GB/s bandwidth. The 5 nm process node from TSMC packs 13,140 million transistors across a 2x 71 mm² die.

In synthetic benchmarks, the 7900X demonstrates strong multi-threaded performance. Its Cinebench R23 multicore score of 43695 and PassMark multithread score of 51406 place it at the 93rd percentile among all CPUs. The single-thread performance is equally robust, with a Cinebench R23 single-core score of 6168 and Geekbench single-core score of 2952. The 3DMark scores show scaling from 1093 single-thread to 12536 max-threads, indicating efficient utilization of the 12 cores.

The nearest CPU rivals in the database include the Intel Core Ultra 5 235 with an average score of 50598 (0.1% lower), AMD Ryzen 9 5900XT at 50738 (0.4% lower), Intel Core i7-13850HX at 50827 (0.5% lower), and Intel Core i9-13980HX at 50944 (0.8% lower). The 7900X's average benchmark score of 50556 sits at the bottom of this group, but the deltas are all under 1%, making them effectively equivalent in aggregate performance.

For Downfall specifically, the CPU's role appears secondary to the GPU. At 1080p Low, the system reaches 312.8 FPS, which is well beyond typical display refresh rates. Even at 1080p Ultra, the 132.7 FPS result suggests the CPU is not bottlenecking the GPU. The 24 threads provide ample headroom for the game's AI, physics, and audio processing, which in a horror title often involve scripted events and dynamic lighting calculations. The 4.70 GHz base clock ensures responsive frame pacing even in scenes with many on-screen entities.

Settings Recommendations

Examining the measured FPS across presets at each resolution, the data suggests that High settings offer the best balance of visual quality and performance. At 1080p, High delivers 212 FPS, which is 62.4% higher than Ultra's 132.7 FPS while providing most of the visual enhancements. At 1440p, High achieves 153.2 FPS, comfortably above the 144 Hz refresh rate common on modern monitors, while Ultra drops to 93.1 FPS. At 4K, High maintains 96 FPS, which is playable on high-refresh displays, while Ultra falls to 60.9 FPS, barely crossing the 60 FPS threshold.

Medium settings provide a middle ground for users who want higher frame rates without sacrificing too much detail. At 1080p Medium, the system produces 252.9 FPS, at 1440p it reaches 185.1 FPS, and at 4K it holds 116.2 FPS. These figures are 19.3% higher than High at 1080p, 20.8% higher at 1440p, and 21% higher at 4K. The consistent ~20% improvement from Medium over High suggests that the preset controls a specific set of GPU-heavy effects that scale linearly.

Low settings are only recommended for competitive play or extremely high refresh rate displays. The 312.8 FPS at 1080p Low is the maximum measured result, providing a 47.6% improvement over High at the same resolution. However, the visual degradation in a horror game, where atmosphere and lighting are critical, makes this preset less desirable for the intended experience.

Ultra settings should be reserved for 1080p or 1440p displays with high refresh rates. The 132.7 FPS at 1080p Ultra and 93.1 FPS at 1440p Ultra are both playable, but the 60.9 FPS at 4K Ultra is borderline for smooth motion. Given that the game launched in 2016, the engine's rendering techniques are well within the RTX 4070's capabilities, but the Ultra preset at 4K still strains the 504.2 GB/s bandwidth.

How This Combo Ranks

The combination of AMD Ryzen 9 7900X and NVIDIA GeForce RTX 4070 ranks 397th out of 1741 tested combos in Downfall, placing it in the top 22.8% of all configurations. This ranking reflects the balance between the 93rd percentile CPU and 81st percentile GPU. The high CPU percentile compensates for the GPU's more modest standing, ensuring that the system is never CPU-limited in this title.

The ranking suggests that this combo outperforms the majority of tested systems, but it is not among the top tier. The 1741 total combos include configurations with higher-end GPUs such as the RTX 4080 and 4090, as well as newer CPUs from the 8000 series. The 397th position indicates that the RTX 4070's 12 GB VRAM and 192-bit bus are the limiting factors for achieving higher ranks, particularly at 4K resolutions.

In the context of Downfall's horror genre, the ranking is particularly meaningful because the game's atmospheric effects and lighting demands benefit from the GPU's ray tracing and tensor cores. The 46 RT cores and 184 tensor cores on the RTX 4070 provide hardware acceleration for these effects, which may explain why the combo performs better than its raw GPU benchmark percentile might suggest. The game's 2016 release date means it does not utilize the latest DirectX 12 Ultimate features, but the GPU's 12_2 support ensures compatibility with any updates.
