Downfall

Downfall is a demanding horror title from 2016, and the combination of the Intel Core i5-14600K and Intel Arc B580 produces a playable but uneven experience that is heavily dependent on resolution and graphics settings. The benchmark data shows that this pairing is fundamentally a 1080p and 1440p performer, with 4K Ultra proving too strenuous for the Arc B580. The most critical finding is the steep performance cliff between Medium and Ultra settings at every resolution, indicating that the GPU's architectural limits are exposed by the game's highest preset.

Resolution Scaling

The performance drop from 1080p to 4K reveals a clear GPU-bound scenario. At Low settings, the average frame rate falls from 185 FPS at 1920x1080 to 82 FPS at 3840x2160, a reduction of 103 FPS. This steep decline demonstrates that the Arc B580's rendering pipeline is the limiting factor as pixel count increases. The scaling is not linear, with the 1440p result of 132 FPS showing a 53 FPS drop from 1080p, while the jump to 4K costs another 50 FPS.

At Medium settings, the same pattern holds. The measured averages are 151 FPS at 1080p, 108 FPS at 1440p, and 67 FPS at 4K. The relative drop from 1440p to 4K is 41 FPS, which is slightly less severe than the Low setting's 50 FPS loss, suggesting that the game's medium preset does not fully saturate the GPU's compute units. The 4K Medium result includes a minimum frame rate of 57 FPS and a maximum of 77 FPS, indicating some frame pacing variance but generally stable performance.

High settings show a more dramatic scaling penalty. The 1080p average is 124 FPS, dropping to 88 FPS at 1440p and then to 55 FPS at 4K. The 33 FPS loss from 1440p to 4K is notable, but the absolute 4K value of 55 FPS is borderline playable for a horror title. Ultra settings are where the scaling becomes prohibitive. The 1080p average of 77 FPS falls to 55 FPS at 1440p and then plummets to 34 FPS at 4K. This final result is below the threshold for smooth gameplay, confirming that 4K Ultra is not viable with this combination.

The data indicates that the CPU is not a limiting factor in resolution scaling. The Core i5-14600K's 14 cores and 20 threads are sufficient to feed the GPU at all tested resolutions, as evidenced by the consistent performance drops that track with pixel count rather than showing any CPU-related plateau. The GPU's 12 GB of VRAM and 456.0 GB/s bandwidth are enough to handle the higher-resolution textures, but the raw shading power of 13.67 TFLOPS is insufficient for the 4K Ultra workload.

Settings Recommendations

The optimal experience for this combination depends on the target resolution. At 1920x1080, the Medium preset is the clear choice. The 151 FPS average with a minimum of 128 FPS provides a wide margin above display refresh rates, and the 23 FPS difference between Medium and High is not worth the visual compromise. The Low preset's 185 FPS is excessive for most displays and sacrifices too much visual fidelity for a horror game where atmosphere matters.

For 2560x1440, High settings deliver the best balance. The 88 FPS average is smooth, and the step down to Medium at 108 FPS does not provide enough of a performance gain to justify the reduced visual quality. The Ultra preset at 55 FPS is playable but sits close to the edge of acceptable performance, and any demanding scene could push it lower. The Low preset at 132 FPS is unnecessary unless the user has a high refresh rate monitor and prioritizes frame rate above all else.

At 3840x2160, the recommendation is Medium settings. The 67 FPS average with a 57 FPS minimum is the only preset that maintains playable performance at this resolution. High settings at 55 FPS are marginal, and Ultra at 34 FPS is unplayable. The Low preset at 82 FPS is viable, but the visual degradation is severe for a game that relies on lighting and shadow effects to create tension. Users targeting 4K should accept Medium settings as the practical ceiling for this GPU.

The measured data shows a consistent pattern where the step from Medium to High costs between 23 and 27 FPS depending on resolution, while the step from High to Ultra costs between 33 and 47 FPS. This non-linear scaling suggests that the Ultra preset enables effects that disproportionately load the GPU's 20 ray tracing cores and 80 ROPs. For the best experience, Medium at 4K or High at 1440p represent the sweet spots where the Arc B580's architecture is not overstressed.

How This Combo Ranks

The combination ranks 2802 out of 3716 tested combos in Downfall, placing it in the lower half of the database. This rank is surprising given the individual component performance. The Core i5-14600K sits in the 90th percentile among all CPUs with an average benchmark score of 48618, while the Arc B580 is in the 68th percentile among GPUs with an average score of 23021. The low combo rank suggests that Downfall is particularly demanding on the GPU architecture, and the Arc B580's strengths in synthetic benchmarks do not translate directly to this game's engine.

The CPU's nearest rivals in synthetic testing include the Intel Xeon Gold 5318H with a delta of -0.2%, the AMD EPYC 4345P at +0.3%, and the Intel Core Ultra 5 245HX at +0.7%. These close scores in general benchmarks do not reflect the gaming performance, as the 14600K's 5.30 GHz boost clock and 24 MB of shared L3 cache provide strong single-thread performance that is more relevant to gaming. The GPU's nearest rivals include the AMD Radeon RX 580 2048SP at -0.2%, the NVIDIA GeForce RTX 2080 at +0.6%, and the NVIDIA GeForce RTX 3080 at -0.7%. The proximity of these scores in the aggregate benchmark hides the fact that the Arc B580's driver overhead and architectural quirks are exposed in a title like Downfall.

The 2802nd rank out of 3716 combinations means that approximately 75% of tested system configurations perform better in this specific game. This is a significant underperformance relative to the component's synthetic scores. The data suggests that users pairing a high-end CPU with this mid-range GPU should expect this combination to be GPU-limited in most scenarios, which is consistent with the resolution scaling analysis.

Measured FPS Breakdown

The measured frame rates provide a complete picture of this combination's capabilities. At 1920x1080, the Low preset achieves 185 FPS average, Medium reaches 151 FPS with a 128-174 FPS range, High delivers 124 FPS, and Ultra drops to 77 FPS. The 108 FPS spread between Low and Ultra at this resolution shows the GPU's headroom at lower pixel counts.

At 2560x1440, the averages are 132 FPS for Low, 108 FPS for Medium with a 92-124 FPS range, 88 FPS for High, and 55 FPS for Ultra. The 1440p results show a tighter grouping, with the gap between Low and Ultra narrowing to 77 FPS. The Medium preset's minimum of 92 FPS indicates that even the most demanding scenes remain above 90 FPS, which is comfortable for most users.

The 3840x2160 results are the most telling. Low settings produce 82 FPS, Medium averages 67 FPS with a 57-77 FPS range, High drops to 55 FPS, and Ultra falls to 34 FPS. The 48 FPS difference between Low and Ultra at 4K is the smallest of any resolution, confirming that the GPU is saturated even at the lowest settings. The 4K Medium result is the only preset that maintains a minimum above 60 FPS, and even that is marginal.

Across all settings, the 1080p to 1440p transition costs between 43 and 53 FPS, while the 1440p to 4K transition costs between 21 and 53 FPS. The largest relative drop from 1440p to 4K occurs at Low settings, where the 50 FPS loss represents a 38% reduction. This pattern is consistent with a GPU that has sufficient memory bandwidth for 1440p but struggles with the 4K pixel fill rate.

GPU Role

The Intel Arc B580 is the primary performance determinant in this combination. The GPU's 12 GB of GDDR6 memory on a 192-bit bus provides 456.0 GB/s of bandwidth, which is sufficient for the 4K textures in Downfall, but the 2560 shading units and 80 ROPs are the limiting factor. The pixel rate of 213.6 GPixel/s and texture rate of 427.2 GTexel/s are modest for a modern GPU, and the 4K Ultra result of 34 FPS reflects this constraint.

The GPU's clock behavior is unusual, with a base clock of 2670 MHz and a boost clock of 2670 MHz, indicating a locked frequency that does not scale with thermal headroom. This is different from most competing GPUs that feature dynamic boost clocks. The memory clock of 2375 MHz (19 Gbps effective) is adequate, but the 192-bit bus width limits the overall bandwidth compared to wider implementations.

The GPU's nearest rival, the NVIDIA GeForce RTX 3080, has a synthetic score only 0.7% higher, yet the real-world performance in Downfall would likely diverge significantly due to architectural differences. The Arc B580's 20 ray tracing cores are underutilized in this title, which appears to rely more on traditional rasterization. The 68th percentile ranking among all GPUs suggests that this is a mid-range part, and the 4K Ultra result of 34 FPS confirms that it is not designed for maximum settings at high resolutions.

The measured data indicates that the GPU's 13.67 TFLOPS of FP32 compute is the bottleneck. At Medium settings, the GPU can maintain 151 FPS at 1080p, but the jump to Ultra at 77 FPS shows that the additional workload from the preset's effects overwhelms the compute units. The 2:1 FP16 ratio of 27.34 TFLOPS suggests that the architecture could benefit from driver-level optimizations that offload some work to the tensor cores, but such optimizations are not evident in these results.

CPU Role

The Intel Core i5-14600K plays a supporting role in Downfall, and the benchmark data shows that it is never the limiting factor. The 14 cores and 20 threads based on Raptor Lake architecture provide ample computational headroom for a game from 2016. The boost clock of 5.30 GHz is particularly important for gaming, as single-thread performance is crucial for game logic and draw call processing.

The CPU's synthetic benchmarks are strong, with a Cinebench R23 multicore score of 24491 and a single-core score of 2064. The Geekbench scores of 16673 multicore and 2491 single-core further confirm that this processor has no trouble keeping up with any GPU. The 90th percentile ranking among all CPUs means that this is a high-end part that will not bottleneck even the fastest graphics cards.

In the context of Downfall, the CPU's 24 MB of shared L3 cache is likely sufficient for the game's data set, and the dual-channel memory support for DDR4 and DDR5 provides enough bandwidth for the GPU to receive data without delays. The 125W TDP and Intel Socket 1700 platform are standard for this generation, and the 10nm process node allows for the high boost clocks that benefit gaming.

The measured FPS data shows no evidence of CPU limitations. If the CPU were a bottleneck, the frame rates would not scale as consistently with resolution changes. The fact that the 4K Low result of 82 FPS is lower than the 1080p Low result of 185 FPS by 103 FPS proves that the GPU is the constraining component. The CPU's 5.30 GHz boost clock and strong single-thread performance ensure that even at 1080p with Low settings, the GPU is the first component to reach its limit.

The Core i5-14600K's nearest rivals in synthetic testing include the Intel Core Ultra 5 245HX at +0.7% and the Intel Core Ultra 5 245 at -0.8%. These close scores indicate that the 14600K is well-positioned in the market, but the real-world gaming performance is what matters. In Downfall, the CPU's role is to provide consistent frame delivery without stutters, and the data shows no frame rate anomalies that would suggest CPU-related issues. The minimum frame rates at Medium settings (128 FPS at 1080p, 92 FPS at 1440p, 57 FPS at 4K) are all within expected ranges for this GPU, confirming that the CPU is not causing dips.
