Downfall

The Intel Core i5-13400F and NVIDIA GeForce RTX 4080 combination delivers a performance curve in Downfall that is heavily dictated by resolution. At 1920x1080, the system is profoundly CPU-bound at lower settings, with the Low preset producing 400 FPS and Medium delivering 327 FPS. The jump from Low to Ultra at 1080p is a 232 FPS drop, landing at 168 FPS, which indicates that even at the highest settings, the GPU is not the limiting factor at this resolution. The data reveals a classic bottleneck inversion: as resolution increases, the load shifts from the processor to the graphics card. At 2560x1440, the spread tightens, with Low producing 285 FPS and Ultra still managing a robust 120 FPS. The most significant scaling occurs at 3840x2160, where the RTX 4080 begins to show its limits. The 4K Ultra preset collapses to 74 FPS, while Low at 4K still achieves 178 FPS. This 104 FPS delta between the lowest and highest settings at 4K highlights that the GPU is the primary constraint only at this resolution, and the Core i5-13400F has sufficient headroom to feed the graphics card effectively at 1440p and below.

Resolution Scaling

The frame rate scaling from 1080p to 4K shows a clear transition in system behavior. At 1920x1080, the average FPS across all settings is exceptionally high, ranging from 168 FPS on Ultra to 400 FPS on Low. This suggests that the Intel Core i5-13400F, with its 10 cores and 16 threads, is the primary driver of performance at this resolution. Moving to 2560x1440, the average FPS drops by approximately 30% across all presets, with the Low setting still producing a very high 285 FPS. This indicates that the CPU is still capable of maintaining high frame rates, but the GPU is beginning to take on more of the workload. The most dramatic scaling occurs at 3840x2160, where the GPU becomes the dominant factor. The 4K High preset yields 119 FPS, which is a 72 FPS reduction compared to the 1440p High result. The 4K Ultra setting, at 74 FPS, is the only configuration that dips below the 100 FPS threshold, suggesting that the RTX 4080’s 16 GB of GDDR6X memory and 716.8 GB/s bandwidth are being fully utilized at this resolution.

The data shows that the system is CPU-limited at 1080p, balanced at 1440p, and GPU-limited at 4K. The 1080p Ultra result of 168 FPS is still higher than the 4K Medium result of 145 FPS, which illustrates the massive computational cost of rendering at 4K. The 4K Medium preset, with a minimum FPS of 123 and maximum of 167, shows a wider variance than the 1440p Medium (198-268 FPS), indicating that the GPU is working closer to its capacity. The 4K Low setting, at 178 FPS, is the only 4K configuration that approaches the 1440p High result of 191 FPS, demonstrating that the RTX 4080 can handle 4K when settings are reduced, but the processor is never the bottleneck at this resolution. Benchmark results indicate that for a smooth 4K experience, the High preset is the ceiling, while 1440p and 1080p users can push to Ultra without sacrificing frame rate stability.

The processor features 10 cores and 16 threads, with a base clock of 2.50 GHz and a boost clock of 4.60 GHz. This configuration provides strong multi-threaded performance, as evidenced by its Cinebench R23 multi-core score of 22604 and Geekbench multi-core score of 11068. The 20 MB of shared L3 cache also helps to reduce memory latency, which is beneficial for gaming. At 1080p, the CPU’s performance is the primary factor limiting frame rates, as the Low preset produces 400 FPS, which is far beyond what most displays can handle. The single-thread performance, with a Cinebench R23 single-core score of 3191, is also strong, ensuring that the CPU does not bottleneck the GPU in most scenarios.

At higher resolutions, the CPU’s role diminishes, as the GPU becomes the limiting factor. However, the data shows that the Core i5-13400F is more than capable of feeding the RTX 4080 at 1440p and 4K. The 4K Ultra preset at 74 FPS indicates that the GPU is fully utilized, and the CPU has enough headroom to handle the game’s simulation and draw calls. The processor’s 65 W TDP suggests that it is an efficient chip, which is a consideration for system builders. The 3dmark benchmarks show a scaling from 1880 in the 2-thread test to 7314 in the 16-thread test, indicating that the CPU benefits from multi-threading. The passmark multi-thread score of 25032 further confirms its strong multi-core capabilities. In Downfall, the CPU’s role is to provide a solid foundation for the GPU, and the data indicates that it does so effectively, with the system being CPU-bound only at 1080p and balanced at higher resolutions.
