# Downfall with Intel Core i5-11400F + AMD Radeon RX 570

The Intel Core i5-11400F paired with the AMD Radeon RX 570 represents a mid-range desktop combination from the early 2020s, and in the horror title Downfall, the measured frame rates reveal a system that is decisively GPU-bound at higher resolutions and settings. The data shows a combo that ranks 1656th out of 1741 tested combinations, placing it in the lower percentile of all tested systems for this specific game, yet the CPU's capable multi-threaded performance suggests it is not the limiting factor in most scenarios.

CPU Role — cores, clocks, and how they relate to this game's results

The Intel Core i5-11400F is a 6-core, 12-thread processor based on the Rocket Lake architecture, manufactured on a 14 nm process. It operates with a base clock of 2.60 GHz and a boost clock of 4.40 GHz, with a 65 W TDP. The CPU's cache hierarchy includes 80 KB of L1 per core, 512 KB of L2 per core, and a shared 12 MB L3 cache. Memory support is DDR4 in a dual-channel configuration, providing a memory bandwidth of 51.2 GB/s.

In synthetic benchmarks, this processor demonstrates solid multi-threaded capability. It scores 14,372 in Cinebench R23 multi-core and 2,029 in single-core, while Geekbench results show 7,579 multi-core and 1,979 single-core. The PassMark multi-thread score is 16,908, with a single-thread score of 2,981. These numbers place the i5-11400F at the 75th percentile among all CPUs, with an average benchmark score of 17,181.

Comparing to its nearest rivals, the i5-11400F is essentially tied with the AMD Ryzen 7 5700U (avgScore 17,189, deltaPct 0), the Intel Core i7-1260P (17,212, -0.2%), and the Intel Core Ultra 7 164U (17,215, -0.2%). It is marginally ahead of the Intel Core i5-1240U (17,141, +0.2%). This indicates that the CPU's raw compute is competitive with those mobile and low-power parts, though the desktop i5 offers higher sustained clocks.

For Downfall, a horror game focused on atmosphere rather than heavy simulation, the CPU is unlikely to be the primary bottleneck. The 12 threads provide ample headroom for game logic and background tasks. Even at low settings where frame rates rise to 90.7 FPS at 1080p, the CPU appears capable of feeding the GPU without becoming a constraint, as the frame rate scaling between resolutions follows a pattern consistent with GPU limitation.

GPU Role — VRAM, clocks, and how they relate to this game's results

The AMD Radeon RX 570 is built on the Polaris 20 chip, using the GCN 4.0 architecture on a 14 nm process from GlobalFoundries. It features 2,048 shading units, 128 texture mapping units, and 32 ROPs. The GPU operates at a base clock of 1168 MHz with a boost clock of 1244 MHz. Memory is 4 GB of GDDR5 on a 256-bit bus, delivering a bandwidth of 224.0 GB/s. The memory clock is 1750 MHz, which translates to 7 Gbps effective.

The GPU's compute capabilities include 5.095 TFLOPS of FP32 performance, with a pixel rate of 39.81 GPixel/s and a texture rate of 159.2 GTexel/s. The card has a 150 W TDP and requires a single 6-pin power connector, with a suggested power supply of 450 W. It supports DirectX 12 (12_0), OpenGL 4.6, and Vulkan 1.3.

In general GPU benchmarks, the RX 570 scores 30,158 on average, placing it at the 74th percentile among all GPUs. Its nearest rivals are surprisingly modern: the NVIDIA GeForce RTX 5060 (avgScore 30,109, deltaPct 0.2%), the AMD Radeon RX 7700 XT (30,097, 0.2%), and the NVIDIA GeForce RTX 5070 Mobile (29,928, 0.8%). This suggests that in aggregate benchmark terms, the RX 570's average score is comparable to much newer hardware, though the game-specific results in Downfall tell a more nuanced story.

The 4 GB VRAM capacity is a potential limiting factor at higher resolutions and settings. At 4K Ultra, the average frame rate drops to 17.0 FPS, which is a dramatic falloff that could indicate memory pressure or simply the GPU's raw compute limits at that resolution.

How This Combo Ranks — use comboRankInGame vs other tested combos

The combination of the Intel Core i5-11400F and AMD Radeon RX 570 ranks 1656th out of 1741 tested combos in Downfall. This places the system in the bottom 5% of all tested configurations, which is a notable finding given that both components individually sit at the 74-75th percentile in their respective benchmark pools.

This discrepancy between component-level percentiles and the in-game combo rank suggests that Downfall is particularly demanding on the GPU, and the RX 570's age and 4 GB VRAM may be more impactful in this title than in synthetic benchmarks. The rank of 1656 indicates that the vast majority of tested systems outperform this combination in this specific game, even though the CPU and GPU are both mid-pack performers in isolation.

The data implies that for Downfall, the GPU is the dominant factor in overall system ranking. The i5-11400F's strong multi-threaded performance (Cinebench R23 multi-core of 14,372) does little to boost the combo's rank when the GPU cannot maintain playable frame rates at higher settings. This is consistent with the measured FPS data, which shows a wide spread between low and ultra settings at every resolution.

Measured FPS Breakdown — resolution by resolution, settings by settings, exact numbers

At 1920x1080, the system delivers its best performance. With Low settings, the average frame rate is 90.7 FPS, which is smooth and playable. Medium settings reduce this to 73.9 FPS, still a comfortable experience. High settings bring the average down to 61.8 FPS, which remains acceptable for most players. Ultra settings, however, drop the average to 41.2 FPS, showing a significant penalty for maximum visual quality.

Moving to 2560x1440, the frame rates decrease substantially. Low settings produce 63.5 FPS average, which is still playable. Medium settings yield 56.5 FPS, and High settings drop to 44.4 FPS. Ultra settings at 1440p result in 27.2 FPS, which is borderline unplayable for a smooth experience.

At 3840x2160, the system struggles. Low settings average 41.7 FPS, which is marginal. Medium settings drop to 35.4 FPS, and High settings fall to 27.1 FPS. Ultra settings at 4K produce just 17.0 FPS, which is not viable for gameplay.

The progression from Low to Ultra at each resolution shows a consistent penalty. At 1080p, the drop from Low to Ultra is 49.5 FPS (90.7 to 41.2). At 1440p, the drop is 36.3 FPS (63.5 to 27.2). At 4K, the drop is 24.7 FPS (41.7 to 17.0). This pattern indicates that the GPU's limitations become more pronounced as resolution increases, with the absolute delta between settings shrinking because the baseline is already low.

Resolution Scaling — how FPS drops from 1080p to 4K and what it says about the limiting component

The scaling from 1080p to 4K reveals a clear GPU bottleneck. At Low settings, the frame rate drops from 90.7 FPS at 1080p to 63.5 FPS at 1440p, a reduction of 30.0%. Moving to 4K, the frame rate drops further to 41.7 FPS, which is 54.0% lower than the 1080p baseline. This scaling is roughly proportional to the increase in pixel count, which is expected when the GPU is the limiting factor.

At Medium settings, the scaling is similar: 73.9 FPS at 1080p, 56.5 FPS at 1440p (a 23.5% drop), and 35.4 FPS at 4K (a 52.1% drop). High settings show 61.8 FPS at 1080p, 44.4 FPS at 1440p (28.2% drop), and 27.1 FPS at 4K (56.1% drop). Ultra settings exhibit the steepest relative decline: 41.2 FPS at 1080p, 27.2 FPS at 1440p (34.0% drop), and 17.0 FPS at 4K (58.7% drop).

The fact that frame rates drop by roughly half from 1080p to 4K across all settings confirms that the RX 570 is the limiting component. If the CPU were the bottleneck, the frame rates would be more consistent across resolutions, as CPU load does not scale with pixel count. The data shows that the i5-11400F is not holding the system back, as even at 1080p Low (90.7 FPS), the CPU has headroom to push higher if the GPU allowed it.

Settings Recommendations

The measured data suggests that the optimal experience for this combination is at 1920x1080 with Medium settings, which delivers 73.9 FPS average. This provides a significant improvement over High settings (61.8 FPS) while maintaining visual fidelity above Low. For players prioritizing smoothness, Low settings at 1080p yield 90.7 FPS, which is the highest frame rate recorded for this combo.

At 2560x1440, Low settings (63.5 FPS) are the only configuration that consistently exceeds 60 FPS. Medium settings at 1440p (56.5 FPS) are acceptable for those willing to accept slightly lower frame rates for better visuals. High settings at 1440p (44.4 FPS) and Ultra (27.2 FPS) are not recommended for a smooth experience.

At 3840x2160, no setting achieves a reliably playable frame rate above 60 FPS. Low settings (41.7 FPS) are the most viable option, but even this is below the threshold for smooth gameplay. The data indicates that 4K should be avoided with this combination.

The Ultra preset, which produces 41.2 FPS at 1080p, 27.2 FPS at 1440p, and 17.0 FPS at 4K, is consistently the worst-performing option and should only be used if visual quality is prioritized over playability. The performance drop from High to Ultra is substantial at every resolution, suggesting that the Ultra preset includes effects that disproportionately tax the RX 570's 4 GB VRAM and 2048 shading units.
