# Downfall with Intel Core i5-13400F + AMD Radeon RX 6600

The benchmark data for Downfall with the Intel Core i5-13400F and AMD Radeon RX 6600 shows a system that handles the horror title with notable headroom at lower resolutions, but reveals distinct scaling patterns as pixel count rises. The combination ranks 1418 out of 1741 tested combos in this game, placing it in the lower-middle portion of the field. Measured frame rates span from 33.4 FPS at 4K Ultra to 174.6 FPS at 1080p Low, giving a clear picture of where this pairing excels and where it struggles.

Resolution Scaling

The frame rate drop from 1080p to 4K is steep across all settings, indicating that the GPU becomes the primary limiting component as resolution increases. At High settings, the average FPS falls from 114.5 at 1080p to 83.6 at 1440p, then to 50.7 at 4K — a reduction of 27% from 1080p to 1440p, and another 39% from 1440p to 4K. This progressive decline aligns with the RX 6600's 8 GB memory capacity and 128-bit bus, which constrain performance as pixel throughput demands grow.

Low settings show the most dramatic scaling: 174.6 FPS at 1080p drops to 127.9 at 1440p (a 27% decrease), then to 76.4 at 4K (a 40% drop from 1440p). The pattern is consistent — each resolution step costs roughly a quarter to two-fifths of the previous frame rate. Medium settings follow the same trajectory: 145.3 FPS at 1080p, 102.1 at 1440p, and 65.3 at 4K.

Ultra settings expose the most severe bottleneck. The 1080p result of 71 FPS falls to 50.6 at 1440p, and then to 33.4 at 4K. The 4K Ultra figure is less than half the 1080p Low result, demonstrating that the combination of high pixel count and demanding visual effects saturates the GPU's capabilities. The scaling from 1440p to 4K at Ultra (a 34% reduction) is slightly less steep than at other settings, suggesting that the frame rate is already approaching a floor imposed by the GPU's raw compute throughput.

The data indicates that at 1080p, the CPU — with its 10 cores and 16 threads — has enough headroom to feed the GPU adequately, as evidenced by the high frame rates at Low and Medium settings. At 4K, however, the GPU's 8.928 TFLOPS FP32 throughput and 224.0 GB/s memory bandwidth become the binding constraints.

GPU Role

The AMD Radeon RX 6600 is built on the RDNA 2.0 architecture with a Navi 23 chip fabricated on TSMC's 7 nm process. Its boost clock of 2491 MHz and game clock of 2044 MHz provide the computational foundation for Downfall's rendering workload. The 8 GB of GDDR6 memory operating at 14 Gbps effective delivers 224.0 GB/s of bandwidth over a 128-bit bus — a configuration that proves adequate for 1080p and 1440p but shows strain at 4K Ultra.

The GPU's 1792 shading units, 112 texture mapping units, and 64 render output units produce a pixel rate of 159.4 GPixel/s and a texture rate of 279.0 GTexel/s. These figures explain why Low settings at 1080p can reach 174.6 FPS — the raw fill rate is sufficient for the reduced pixel workload. However, the 4K Ultra result of 33.4 FPS suggests that the combination of 8.3 million pixels plus high-fidelity effects overwhelms the available bandwidth and compute units.

The RX 6600's passmark G3D score of 15096 and its 69th percentile ranking among all GPUs place it as a mid-tier performer. Its nearest rival, the AMD Radeon 890M, scores 25246 in the average benchmark — a 0% delta — while the NVIDIA GeForce RTX 3060 Ti sits 0.5% higher at 25120. In Downfall specifically, the measured results show the RX 6600 delivering playable frame rates at 1440p High (83.6 FPS) but falling to just above the 30 FPS threshold at 4K Ultra.

The memory configuration deserves attention: 8 GB is sufficient for this 2016 horror title at most settings, but the 128-bit bus creates a bandwidth ceiling. The 224.0 GB/s figure is modest by current standards, and the scaling data suggests that Downfall's texture streaming and particle effects are sensitive to memory throughput. The GPU's 64 ROPs handle pixel output efficiently at lower resolutions, but the 4K results indicate that pixel fill becomes a limiting factor.

Settings Recommendations

The measured rows provide clear guidance for optimal settings. At 1080p, Medium settings deliver 145.3 FPS — a 27% improvement over High's 114.5 FPS while maintaining visual quality that should be acceptable for a horror title focused on atmosphere. The jump from Medium to Ultra at 1080p costs more than half the frame rate (145.3 to 71 FPS), making Ultra a poor trade-off for the added detail.

For 1440p, High settings at 83.6 FPS represent the sweet spot. This maintains smooth motion while providing the visual fidelity that makes Downfall's horror elements effective. Medium at 1440p offers 102.1 FPS but sacrifices some shadow and texture quality. Ultra at 1440p drops to 50.6 FPS, which is playable but leaves little headroom for demanding scenes.

At 4K, the choices become constrained. High settings yield 50.7 FPS, which is above the 30 FPS minimum but below the 60 FPS target that many players prefer. Medium at 4K provides 65.3 FPS and is arguably the best balance for 4K displays. Low settings at 4K reach 76.4 FPS but strip away much of the game's visual atmosphere. Ultra at 4K at 33.4 FPS should be avoided unless the player prioritizes maximum detail over smoothness.

The data suggests that Medium settings across all resolutions provide the most consistent experience relative to the GPU's capabilities. The frame rate scaling from 1080p Medium (145.3) to 1440p Medium (102.1) to 4K Medium (65.3) shows a predictable degradation that keeps performance above 60 FPS at 1080p and 1440p, and near the playable threshold at 4K.

CPU Role

The Intel Core i5-13400F provides the processing foundation for this system. With 10 cores and 16 threads operating at a base clock of 2.50 GHz and boost clock of 4.60 GHz, the CPU delivers strong multi-threaded performance. Its Cinebench R23 multi-core score of 21279 and single-core score of 3004 indicate robust capability for game logic, physics, and AI calculations that Downfall's horror gameplay requires.

The CPU's 20 MB of shared L3 cache and dual-channel memory support for DDR4/DDR5 provide adequate data feeding for the GPU. The 3DMark 16-thread score of 7314 and single-thread score of 960 suggest that the CPU can handle down to 1080p Low settings without becoming a bottleneck — the 174.6 FPS result at that configuration is likely near the game's engine limit rather than a CPU constraint.

The i5-13400F's average benchmark score of 25236 places it in the 82nd percentile of all CPUs. Its nearest rival, the AMD Ryzen 5 5600X3D, scores 25365 — a 0.5% advantage — while the Intel Core i7-13620H trails by 0.1% at 25201. These close margins indicate that the CPU is competitively positioned within its performance class.

In Downfall specifically, the CPU's role becomes apparent in the scaling behavior. At 1080p Low, the system achieves 174.6 FPS, which is 2.3 times the 4K Ultra result of 33.4 FPS. If the CPU were severely limited, the 1080p results would show less variation across settings. Instead, the consistent multi-setting performance at 1080p (71-174.6 FPS range) suggests the CPU has ample headroom, with the GPU determining final frame rates.

The CPU's 65 W TDP and 10 nm process node from Intel make it an efficient choice, but the benchmark scores are the more relevant metric here. The PassMark multi-thread score of 25032 and single-thread score of 3634 both support the conclusion that this processor can sustain high frame rates in a game like Downfall, which does not demand extreme CPU throughput.

Measured FPS Breakdown

At 1920x1080, the RX 6600 delivers its strongest results. Low settings produce 174.6 FPS, Medium reaches 145.3 FPS, High achieves 114.5 FPS, and Ultra drops to 71 FPS. The spread from Low to Ultra represents a 59% reduction in performance, showing that visual effects at Ultra impose a significant cost even at the lowest resolution.

At 2560x1440, the frame rates shift downward across all settings. Low yields 127.9 FPS, Medium produces 102.1 FPS, High delivers 83.6 FPS, and Ultra falls to 50.6 FPS. The ratio between Low and Ultra at 1440p is approximately 2.5:1, slightly wider than at 1080p, indicating that the GPU's pixel processing capabilities are becoming more stressed.

At 3840x2160, the results compress into a narrower range. Low delivers 76.4 FPS, Medium provides 65.3 FPS, High reaches 50.7 FPS, and Ultra drops to 33.4 FPS. The difference between Low and Ultra at 4K is 43 FPS, compared to 103.6 FPS at 1080p — the GPU's limits compress the performance envelope as resolution increases.

The 1080p Medium result of 145.3 FPS is particularly notable when compared to the 1440p Medium figure of 102.1 FPS. This 30% reduction demonstrates the cost of the additional 1.6 million pixels. Similarly, the 1440p High result of 83.6 FPS to 4K High's 50.7 FPS represents a 39% drop for the 5.3 million additional pixels.

The Ultra settings across resolutions show the most consistent absolute frame rates: 71, 50.6, and 33.4 FPS at 1080p, 1440p, and 4K respectively. This roughly 30% decline per resolution step suggests that Ultra settings engage the GPU's compute units and memory subsystem in a way that scales predictably with pixel count, without hitting a bandwidth cliff until 4K.
