Downfall

The Intel Core i5-13400F and AMD Radeon RX 7900 XT combination delivers exceptionally high frame rates in Downfall, a 2016 horror title. The data shows this pairing ranks 366th out of 1,741 tested hardware combinations, placing it in the top 21% of all systems. The CPU, a 10-core, 16-thread Raptor Lake-S part with a 2.50 GHz base and 4.60 GHz boost clock, provides ample processing headroom for a game of this era. Its benchmark scores, including a Cinebench R23 multi-core result of 21,279 and a single-core score of 3,004, indicate strong per-thread performance that prevents bottlenecking even at lower resolutions where the GPU is less taxed. The processor’s 20 MB of shared L3 cache and support for both DDR4 and DDR5 memory further contribute to its ability to feed frames quickly, though the game’s age means it rarely stresses all 16 threads.

In terms of relative standing, the i5-13400F sits at the 82nd percentile among all CPUs, with an average benchmark score of 25,236. Its nearest rivals are tightly clustered: the Intel Core i7-13620H scores 25,201 (0.1% higher), the AMD Ryzen 5 5600X3D scores 25,365 (0.5% higher), and the AMD EPYC 9474F scores 25,103 (0.5% higher). These sub-1% deltas show that the 13400F is squarely in the middle of a performance plateau, meaning any differences in Downfall frame rates at CPU-bound settings would be negligible. The 3DMark results reinforce this: a single-thread score of 960 and a 2-thread score of 1,880 suggest that even lightly threaded workloads, common in horror game logic and AI, are handled with ease.

The CPU’s role is most evident at 1080p Low settings, where the system achieves 337.3 FPS. That number is so high that the CPU must be the limiting factor, as the GPU is unlikely to be saturated at that frame rate. Conversely, at 4K Ultra, the frame rate drops to 63.8 FPS, indicating the GPU takes over as the primary constraint. The benchmark data suggests the i5-13400F is never the weak link in this pairing, as its 82nd percentile ranking and strong multi-threaded scores (PassMark multi-thread of 25,032, Geekbench multi-core of 10,971) provide a robust foundation for the RX 7900 XT to operate without waiting on the processor.

Resolution Scaling

The resolution scaling data reveals how the system’s bottleneck shifts as pixel count increases. At 1080p Low, the average FPS is 337.3, which is exceptionally high and indicates the CPU is doing the heavy lifting. Moving to 1440p Low, the frame rate drops to 238.9 FPS, a 29.2% reduction, while 4K Low yields 147.7 FPS, another 38.2% drop from 1440p. This pattern shows that even at Low settings, the GPU becomes progressively more involved as resolution climbs, but the CPU remains capable of keeping up.

At High settings, the scaling is more pronounced: 1080p High delivers 224.9 FPS, 1440p High drops to 160 FPS (28.9% decrease), and 4K High falls to 101.9 FPS (36.3% decrease from 1440p). The consistent ~30% drops between resolutions suggest a balanced system where neither component is severely bottlenecked. However, the Ultra settings tell a different story: 1080p Ultra runs at 141.2 FPS, but 4K Ultra falls to 63.8 FPS, a 54.8% drop from 1440p Ultra’s 103.7 FPS. This steeper decline at 4K Ultra indicates the GPU is the limiting factor at the highest settings, as the RX 7900 XT’s 51.48 TFLOPS of FP32 performance is stretched by the increased pixel workload.

The data suggests that at 1080p and 1440p, the system is well-balanced, with the CPU providing enough headroom for the GPU to render efficiently. At 4K, particularly with Ultra settings, the GPU’s raw compute (51.48 TFLOPS) and memory bandwidth (800.0 GB/s) become the primary determinants of performance. The 63.8 FPS at 4K Ultra is still playable, but the dramatic scaling from 1080p Ultra highlights that this resolution/settings combination is the most demanding scenario for the hardware.

Measured FPS Breakdown

At 1920x1080, the system delivers outstanding results across all settings. Low settings produce the highest average at 337.3 FPS, followed by Medium at 276.8 FPS and High at 224.9 FPS. Ultra settings reduce the average to 141.2 FPS, which is still well above the 60 FPS threshold for smooth gameplay. The spread from Low to Ultra is 196.1 FPS, indicating that the graphical settings have a substantial impact on performance, but even the most demanding preset remains fluid.

Moving to 2560x1440, the frame rates remain high but begin to show the GPU’s increased load. Low settings average 238.9 FPS, Medium drops to 194.7 FPS, and High settles at 160 FPS. Ultra at 1440p produces 103.7 FPS, which is a 26.6% decrease from 1080p Ultra. This resolution is ideal for high-refresh-rate gaming, as even the Ultra preset stays above 100 FPS.

At 3840x2160, the system still performs admirably but with more variance. Low settings average 147.7 FPS, Medium hits 119.7 FPS, and High manages 101.9 FPS. Ultra at 4K produces 63.8 FPS, which is the lowest measured result but remains playable. The scaling from 1080p to 4K at Ultra is a 54.8% reduction, showing that the GPU is the primary constraint at this resolution. Across all resolutions, the Low-to-Ultra gap widens as resolution increases: 196.1 FPS at 1080p, 135.2 FPS at 1440p, and 83.9 FPS at 4K. This indicates that the GPU’s computational resources are more heavily taxed at higher resolutions, reducing the relative impact of settings changes.

GPU Role

The AMD Radeon RX 7900 XT is the dominant component in this pairing, particularly at higher resolutions and settings. Built on the RDNA 3.0 architecture with a 5 nm process from TSMC, the GPU features 5,376 shading units, 336 texture mapping units, and 192 raster operations pipelines. Its 84 ray tracing cores and 51.48 TFLOPS of FP32 performance provide substantial compute power for Downfall’s rendering demands. The GPU’s boost clock of 2,394 MHz and game clock of 2,025 MHz ensure consistent performance under load, while the 20 GB of GDDR6 memory on a 320-bit bus delivers 800.0 GB/s of bandwidth.

The GPU’s benchmark results place it at the 82nd percentile among all GPUs, with an average score of 38,358. Its nearest rivals are the NVIDIA GeForce RTX 5080 Mobile (38,349, 0% delta) and the NVIDIA CMP 70HX (38,225, 0.3% slower). The RX 7900 XT’s PassMark G3D score of 29,009 and Geekbench OpenCL score of 169,834 confirm its high-end positioning. In Downfall, this translates to the GPU being the limiting factor at 4K Ultra, where the 63.8 FPS result is 54.8% lower than the 1440p Ultra score of 103.7 FPS. The GPU’s 84 RT cores and 192 ROPs handle the game’s lighting and post-processing effects, while the 336 TMUs manage texture filtering, which is critical for the horror genre’s detailed environments.

The RX 7900 XT’s memory configuration is particularly relevant for Downfall’s high-resolution performance. The 20 GB VRAM capacity is far beyond the game’s requirements, ensuring no texture swapping occurs even at 4K Ultra. The 800.0 GB/s bandwidth allows for rapid data transfer between the GPU and memory, which is essential for maintaining high frame rates in scenes with complex geometry and particle effects. The GPU’s 300 W TDP and dual-slot design indicate it is a power-hungry part, but its performance in this title justifies the power draw. The data shows that at 1080p, the GPU is not fully utilized, as evidenced by the 337.3 FPS at Low settings, but at 4K Ultra, it is clearly the bottleneck, with the CPU providing more than enough headroom. This balance makes the RX 7900 XT the primary driver of Downfall’s performance, particularly for users targeting 1440p or 4K with high visual fidelity.
