Downfall

The AMD Ryzen 7 5800X paired with the Intel Arc B580 presents a compelling data set for "Downfall," a horror title from 2016. The measured frame rates across resolutions and presets reveal a system that is capable of delivering high refresh rate experiences at 1080p, but which faces significant challenges at 4K Ultra settings. This analysis breaks down the recorded performance metrics to provide clear guidance on configuration and expectations for this specific hardware combination.

Settings Recommendations

The data shows a clear performance hierarchy across the four tested presets at every resolution. At 1920x1080, the system delivers an average of 183.9 FPS on Low, 150.8 FPS on Medium, 122.5 FPS on High, and 78.1 FPS on Ultra. The jump from Low to Medium costs roughly 33 FPS, while the progression to High costs another 28 FPS. The Ultra preset, however, is by far the most demanding, incurring a further 44 FPS drop from High.

At 2560x1440, the pattern is similar but with reduced headroom. Low settings produce 133.1 FPS, Medium 108.9 FPS, and High 89.7 FPS. The Ultra preset falls to 53.3 FPS. At 3840x2160, the situation tightens considerably. Low yields 83.9 FPS, Medium 70 FPS, and High 58.2 FPS, while Ultra drops to a barely playable 35.7 FPS. The data suggests that High settings provide the optimal balance for most users. At 1080p and 1440p, High stays comfortably above the 60 FPS threshold, with 122.5 and 89.7 FPS respectively. Even at 4K, High maintains an average of 58.2 FPS, which is a more fluid experience than the Ultra preset.

For users prioritizing maximum visual fidelity at 1080p, the Ultra preset's 78.1 FPS is still smooth. However, the steep performance penalty—a 36% drop from High—makes it a less attractive option than the more moderate High preset, which retains most visual enhancements without halving the frame rate. At 1440p, Ultra should be avoided unless the user has a 60 Hz display, as 53.3 FPS is below the ideal range for high-refresh monitors. The Low preset is unnecessary at 1080p or 1440p, but at 4K it becomes a viable option for users who prioritize frame rate over visuals, as it is the only preset that consistently stays above 60 FPS at that resolution.

GPU Role

The Intel Arc B580 is the primary driver of performance scaling in this configuration. The GPU's architecture, Xe2-HPG on a 5 nm process, is built on the Battlemage generation. It features 2560 shading units, 160 TMUs, and 80 ROPs. The memory subsystem is substantial, with 12 GB of GDDR6 on a 192-bit bus, delivering a bandwidth of 456.0 GB/s. The core clocks are fixed at 2670 MHz for both base and boost, which is a relatively high operating frequency.

The VRAM capacity of 12 GB is a notable asset for "Downfall," a game where texture-heavy horror environments can be demanding. While the data does not explicitly measure VRAM usage, the substantial frame rate drops at higher presets and resolutions suggest that both memory bandwidth and capacity are being exercised. The 456.0 GB/s of bandwidth is likely a contributing factor to the strong performance at 1080p and 1440p, where the system achieves high average frame rates. The GPU's compute capabilities, measured at 13.67 TFLOPS for FP32, are sufficient to handle the game's rendering load at lower resolutions, but the 4K Ultra results indicate that the B580 is pushed to its limits.

The GPU's benchmark scores place it in a specific performance tier. With a percentileVsAllGpus of 66, it outperforms the average GPU. Its nearest rivals include the NVIDIA GeForce RTX 4060, which has an avgBenchmarkScore of 23181, just 0.7% higher than the B580's 23021. This proximity in raw compute benchmarks is reflected in the gaming data, where the B580 holds its own. The measured FPS at 1080p High (122.5) and 1440p High (89.7) indicate that the GPU is not the limiting factor at these settings, as the frame rates are well above common refresh rate targets. However, the steep decline at 4K Ultra (35.7 FPS) highlights that the GPU's 192-bit memory bus and 12 GB VRAM are not sufficient to handle the most demanding configuration.

Resolution Scaling

The performance degradation from 1080p to 4K is substantial, indicating a shift in the system's bottleneck. At High settings, the average FPS drops from 122.5 at 1080p to 89.7 at 1440p, a decline of 26.8%. Moving to 4K, the frame rate falls further to 58.2, representing a 35.1% drop from 1440p and a 52.5% drop from 1080p. This pattern is consistent with a GPU-bound scenario at higher resolutions.

The data suggests that the CPU is less of a limiting factor at 4K. At 1080p Low, the system achieves 183.9 FPS, which is a very high frame rate that likely approaches the CPU's maximum output capability for this game. The scaling from Low to Ultra at 1080p shows a 57.5% reduction in FPS, which is primarily due to increased GPU load. At 4K, the scaling is even more severe, with Ultra delivering only 35.7 FPS compared to Low's 83.9 FPS, a 57.5% drop. The increasing gap between Low and Ultra FPS as resolution increases is a classic sign that the GPU is becoming the primary constraint.

The resolution scaling also reveals that the system is well-balanced for 1440p. The 89.7 FPS at High is a strong result, indicating the B580 has enough headroom to handle the increased pixel count without being overwhelmed. At 4K, however, the data shows that the system is firmly GPU-limited. The difference between 1440p High and 4K High is 31.5 FPS, while the difference between 1080p High and 1440p High is 32.8 FPS. This similar absolute drop suggests that the GPU's performance scales roughly linearly with pixel count until it hits a ceiling.

How This Combo Ranks

Within the benchmark database, this specific combination of the AMD Ryzen 7 5800X and Intel Arc B580 ranks 1333 out of 1741 tested combos for "Downfall." This places it in the lower-middle portion of the overall distribution. The rank reflects the measured performance of this specific pairing, which is notable because the individual components have different performance characteristics.

The GPU's average benchmark score of 23021 places it in the 66th percentile of all GPUs, while the CPU's average score of 27606 places it in the 84th percentile of all CPUs. The combination rank of 1333 out of 1741 suggests that, while both components are capable in their own right, the pairing does not boost to the top tier for this particular game. This could be due to the game's age and its reliance on single-threaded performance, where the CPU's 3dmark_single_thread score of 943 is relatively modest compared to newer processors.

The combo's rank also indicates that there are many other configurations that achieve higher frame rates in "Downfall." This is likely due to the fact that the game, released in 2016, may not fully utilize the 8 cores and 16 threads of the Ryzen 7 5800X, nor the Xe2-HPG architecture of the B580. The measured data shows that the system is capable of high frame rates at lower resolutions, but the overall rank suggests that the system's performance is average relative to the entire database. The 1741 tested combos include many with newer, higher-end CPUs and GPUs that can achieve higher frame rates, particularly at 4K.

CPU Role

The AMD Ryzen 7 5800X is a 5000 series processor based on the Zen 3 architecture, codenamed Vermeer. It has 8 cores and 16 threads, with a base clock of 3.80 GHz and a boost clock of 4.70 GHz. The CPU's cache hierarchy includes 64 KB of L1 per core, 512 KB of L2 per core, and 32 MB of L3 cache. It supports DDR4 memory in a dual-channel configuration, with a theoretical bandwidth of 51.2 GB/s.

In "Downfall," the CPU's role appears to be secondary to the GPU at higher resolutions, but it becomes more relevant at 1080p. The data shows that at 1080p Low, the system achieves 183.9 FPS, which is a very high frame rate. This indicates that the CPU is capable of feeding the GPU with enough data to sustain high performance. The CPU's multithreaded capabilities, as measured by cinebench_r23_multicore score of 23571, are robust. However, the game's engine, released in 2016, may not be optimized to use all 16 threads effectively.

The CPU's performance relative to its rivals is tight. Its avgBenchmarkScore of 27606 is just 0.3% higher than the AMD Ryzen 7 5800's 27535, and only 0.8% higher than the Intel Core i5-12600KF's 27827. This suggests that for this game, the specific CPU model has a minimal impact on overall performance, as long as it has sufficient single-thread performance. The boost clock of 4.70 GHz is likely the key factor in maintaining high frame rates at 1080p, as the game's performance at that resolution is more dependent on CPU speed than core count. The 3dmark_2_threads score of 1846 and 3dmark_4_threads score of 3543 indicate that the CPU's performance scales well with a few active threads, which is typical for games of this era. The data shows that the CPU is not a bottleneck at 1440p or 4K, where the GPU's limitations are more pronounced.
