# Downfall with Intel Core i5-13400F + NVIDIA GeForce RTX 5080

The Intel Core i5-13400F paired with the NVIDIA GeForce RTX 5080 delivers exceptional performance in Downfall, a 2016 horror title. Across all tested resolutions and settings, this combination produces frame rates that range from very playable at 4K Ultra to extraordinarily high at 1080p Low. The data reveals a system that is overwhelmingly GPU-bound at higher resolutions, with the CPU's strong multi-threaded capabilities only becoming a limiting factor at the lowest settings where frame rates approach 400 FPS. This combo ranks 78th out of 1,741 tested combinations, placing it in the top 4.5% of all systems evaluated for this game.

Resolution Scaling

The measured FPS data shows a clear and consistent scaling pattern as resolution increases. At 1080p High, the system achieves 285.8 FPS, which drops to 204.1 FPS at 1440p High and further to 123.6 FPS at 4K High. This represents a 28.6% reduction from 1080p to 1440p, and a 56.8% reduction from 1080p to 4K. The scaling is not perfectly linear, indicating that different components become more or less dominant at each resolution step.

At Low settings, the resolution scaling is even more dramatic. The system produces 406.6 FPS at 1080p, 304.2 FPS at 1440p, and 187.8 FPS at 4K. The 4K figure is only 46.2% of the 1080p number, suggesting that at these extremely high frame rates, the CPU is struggling to keep up with the GPU's output. The 1440p to 4K drop of 38.3% is particularly steep, indicating that the GPU is being pushed harder at 4K while the CPU overhead remains relatively constant.

Ultra settings show the most significant performance hit across resolutions. At 1080p Ultra, the system manages 176.9 FPS, dropping to 130.2 FPS at 1440p and 80.8 FPS at 4K. The 4K Ultra performance is only 45.7% of the 1080p Ultra figure, which is the largest relative drop of any settings tier. This pattern suggests that Ultra settings impose a heavy GPU workload that scales disproportionately with resolution, likely due to increased shading complexity and texture memory pressure.

The data indicates that at 1080p, the system is often CPU-limited, particularly at Low and Medium settings where frame rates exceed 340 FPS. As resolution increases to 4K, the GPU becomes the primary bottleneck, with the 80.8 FPS at 4K Ultra representing a scenario where the RTX 5080's raw compute is the limiting factor. The RTX 5080's 16 GB of GDDR7 memory on a 256-bit bus with 960.0 GB/s bandwidth appears sufficient even at 4K Ultra, as the frame rate drop is more consistent with compute limitations than memory bandwidth constraints.

CPU Role

The Intel Core i5-13400F is a 10-core, 16-thread processor based on Raptor Lake architecture, with a base clock of 2.50 GHz and a boost clock of 4.60 GHz. Its 20 MB of shared L3 cache and 1.25 MB L2 per core provide substantial on-die storage for game data. In Downfall, the CPU's role is most evident at 1080p Low, where the 406.6 FPS result approaches the practical limit of what this processor can feed to the GPU.

The CPU's synthetic benchmarks support its strong gaming performance. Its Cinebench R23 multi-core score of 21,279 and single-core score of 3,004 indicate robust multi-threaded and single-threaded capabilities. The 3DMark 16-thread score of 7,314 and max-thread score of 7,307 show that the processor scales well with thread count, which is relevant for a horror game that may spawn background processes. The single-thread 3DMark score of 960 is modest, but the 2-thread score of 1,880 demonstrates good dual-core performance for games that rely primarily on one or two main threads.

Comparing the i5-13400F to its nearest rivals, the data shows it is statistically indistinguishable from the Intel Core i7-13620H, with a deltaPct of 0.1%. It is also within 0.5% of the AMD Ryzen 5 5600X3D and the AMD EPYC 9474F, and matches the AMD Ryzen AI 5 PRO 340 with a 0.5% delta. This tight grouping means the CPU is unlikely to be a differentiator in Downfall when paired with such a powerful GPU, as all these processors provide sufficient frame generation capability.

At 1080p Medium, the 347.6 FPS result is still very high but notably lower than the 406.6 FPS at Low settings. This 14.5% reduction suggests that even at Medium settings, the CPU's instruction throughput and memory access patterns begin to show some impact, though the GPU is still the dominant factor. The 1080p High result of 285.8 FPS further confirms this trend, with the CPU maintaining adequate performance headroom.

GPU Role

The NVIDIA GeForce RTX 5080 is the clear performance driver in this combination, particularly at higher resolutions and settings. With 10,752 shading units, 336 texture mapping units, and 112 ROPs, this Blackwell 2.0 architecture GPU delivers massive compute throughput. The 56.28 TFLOPS of FP32 performance and 879.3 GTexel/s texture rate provide the raw power needed for Downfall's horror visuals, which likely rely heavily on dynamic lighting and particle effects.

The GPU's memory subsystem is a key strength. Its 16 GB of GDDR7 memory operates at 1,875 MHz (30 Gbps effective) across a 256-bit bus, yielding 960.0 GB/s of bandwidth. This configuration is well-suited for 4K Ultra settings, where the 80.8 FPS result indicates that texture streaming and memory capacity are not limiting factors. The RTX 5080's 84 RT cores and 336 tensor cores also suggest that any ray-traced effects in Downfall would be handled efficiently, though the game's 2016 release date likely predates widespread RT implementation.

The GPU's benchmark scores place it in the 89th percentile of all GPUs, with an average benchmark score of 59,188. Its Passmark G3D score of 36,565 and 3DMark Steel Nomad DX12 score of 8,637 demonstrate strong DirectX 12 performance, which is relevant for a game running on modern APIs. The Geekbench OpenCL score of 264,461 and Vulkan score of 257,942 show excellent compute and graphics API flexibility.

Comparing the RTX 5080 to its nearest rivals, the data shows it is 1.6% ahead of the Intel Arc A570M and 2.5% ahead of the Intel Arc A580, while being 1.9% behind the Intel Arc Pro A60 and 2.6% ahead of the AMD Radeon Pro W5500X. These small deltas are surprising given the RTX 5080's premium positioning, but they reflect the benchmark averages across multiple workloads rather than game-specific performance.

The GPU's role in Downfall is most pronounced at 4K Ultra, where the 80.8 FPS result is a 34.1% reduction from the 4K High score of 123.6 FPS. This significant drop indicates that Ultra settings impose a heavy shader and pixel workload that the RTX 5080's 293.1 GPixel/s pixel rate must handle. The 4K Medium result of 152.6 FPS shows that reducing settings from Ultra to Medium nearly doubles performance, confirming that the GPU is the primary constraint at these resolutions.

How This Combo Ranks

In the overall ranking for Downfall, this Intel Core i5-13400F and NVIDIA GeForce RTX 5080 combination achieves rank 78 out of 1,741 tested combos. This places it in the top 4.5% of all systems, which is an outstanding result for a mid-range CPU paired with a high-end GPU. The ranking suggests that the combination is well-balanced for this game, with neither component severely bottlenecking the other in most scenarios.

The combo's rank of 78 becomes more impressive when considering the breadth of tested hardware. With 1,741 total combinations, the i5-13400F + RTX 5080 outperforms 1,663 other systems, including many that likely feature more expensive CPUs. This indicates that Downfall is not heavily CPU-dependent at typical gaming resolutions, allowing the RTX 5080 to dominate performance.

The ranking also implies that the i5-13400F's 10 cores and 16 threads are sufficient for this horror title. The game's 2016 release date means it likely does not take advantage of more than 8-16 threads, and the CPU's 3DMark 8-thread score of 5,591 suggests solid mid-range multi-threading. The 82nd percentile ranking of the CPU among all processors, combined with the GPU's 89th percentile, indicates a well-matched pairing.

However, the combo ranking may be held back by the CPU at lower resolutions. At 1080p Low, the 406.6 FPS result is likely near the CPU's maximum frame generation capability. Systems with higher-performing CPUs might achieve even higher frame rates at this resolution, potentially pushing the combo higher in the rankings. Despite this, the 78th rank is a strong showing that validates the i5-13400F's ability to feed the RTX 5080 effectively in most gaming scenarios.
