Downfall

The AMD Ryzen 7 5800XT paired with the Intel Arc B580 delivers a performance profile in Downfall that is heavily dictated by resolution and settings, with the data revealing a clear shift in bottleneck behavior as pixel count increases. This 8-core, 16-thread Zen 3 processor, with a boost clock of 4.80 GHz, provides ample headroom, while the Arc B580’s 12 GB of GDDR6 memory on a 192-bit bus becomes a defining factor at 4K. The measured results show a combination that is remarkably capable at 1080p, but which requires careful settings management to maintain smooth frame rates at higher resolutions.

Resolution Scaling

The frame rate drop from 1080p to 4K is substantial and reveals the GPU as the primary limiting component at higher resolutions. At High settings, the average FPS falls from 124.5 at 1920x1080 to 89.1 at 2560x1440, a 28.4% reduction, and then further to 57.0 at 3840x2160, a 36% reduction from the 1440p figure. This steep, compounding decline is classic evidence of a GPU-bound scenario; the Ryzen 7 5800XT’s 8 cores are not the constraint here.

The scaling pattern is consistent across all settings. At Low settings, the 1080p result of 180.8 FPS drops to 130.9 at 1440p (a 27.6% decrease) and then to 80.1 at 4K (a 38.8% decrease from 1440p). The percentage drops are similar across the settings presets, indicating that the relative cost of increasing resolution is independent of the graphical fidelity. For instance, the Ultra preset sees a 33.5% drop from 1080p to 1440p (80.1 to 53.3 FPS) and a further 38.7% drop to 4K (53.3 to 32.7 FPS). This consistent behavior suggests that the fill-rate and memory bandwidth demands of higher resolutions are the dominant factors, not the CPU’s ability to feed the frame.

The data further suggests that the CPU is rarely the bottleneck. At 1080p Low, the system produces 180.8 FPS, a very high figure that indicates the processor can handle the game’s logic and draw calls efficiently. However, the gap between Low and Ultra at 1080p is 100.7 FPS (180.8 vs 80.1), which is a significant spread. This spread narrows at 4K, where the difference between Low and Ultra is 47.4 FPS (80.1 vs 32.7). The narrowing gap at higher resolutions is a hallmark of a GPU that is becoming saturated, as the pixel workload grows, the relative cost of higher settings becomes more pronounced.

FAQ

Q: What is the performance difference between Low and Ultra settings at 1080p?

A: At 1920x1080, the average FPS drops from 180.8 on Low settings to 80.1 on Ultra. This represents a 55.7% reduction in performance when moving to the highest preset.

Q: Can this combo maintain 60 FPS at 4K?

A: At 3840x2160, only the Low preset achieves an average above 60 FPS, with a score of 80.1. The Medium preset is at 65.2 FPS, while High (57.0 FPS) and Ultra (32.7 FPS) fall below the 60 FPS threshold.

Q: How does the 1440p performance compare to 1080p?

A: At High settings, the average FPS at 2560x1440 is 89.1, which is 35.4 FPS lower than the 124.5 FPS seen at 1920x1080. This indicates a significant performance hit when moving to 1440p.

Q: Is the CPU or GPU the limiting factor in this game?

A: The data indicates the Intel Arc B580 is the primary limiter at resolutions above 1080p. The CPU’s ability to produce 180.8 FPS at 1080p Low, coupled with the steep FPS drops when resolution increases, points to GPU-bound performance.

Q: What is the best preset for high refresh rate 1440p gaming?

A: For a 1440p target, the Low preset delivers 130.9 FPS, and Medium delivers 109.8 FPS. The High preset at 89.1 FPS is also viable for 60+ FPS gaming, but Ultra at 53.3 FPS is not.

Q: How does the Ultra setting scale from 1440p to 4K?

A: The Ultra preset drops from 53.3 FPS at 2560x1440 to 32.7 FPS at 3840x2160. This is a 38.7% reduction in average frame rate, showing the high cost of pushing this setting to 4K.

GPU Role

The Intel Arc B580 plays a decisive role in the measured Downfall results. Its 12 GB of GDDR6 memory and 456.0 GB/s of bandwidth are likely the key attributes that allow it to handle the 4K resolution, albeit with reduced settings. The GPU’s base and boost clocks are both listed at 2670 MHz, and the memory clock is 2375 MHz (19 Gbps effective). These specifications, part of the Xe2-HPG architecture on a 5 nm process, deliver a peak FP32 performance of 13.67 TFLOPS.

The data suggests that the GPU’s compute and memory resources are strained at higher settings. The difference between Medium and Ultra at 4K is substantial: 65.2 FPS vs 32.7 FPS. This near-halving of performance indicates that the Ultra preset likely introduces effects that heavily tax the B580’s 2560 shading units and 80 ROPs. In contrast, the jump from Low to Medium at 4K is smaller (80.1 to 65.2 FPS), suggesting that the initial tier of settings is less demanding.

The GPU’s performance percentile versus all GPUs is 66, and its average benchmark score is 23021. In the context of this game, the B580’s nearest rivals include the NVIDIA GeForce RTX 4060, which has an avg score of 23181 and a deltaPct of -0.7, meaning the B580 is 0.7% slower in aggregate benchmarks. However, the in-game results show that the B580 can produce very high frame rates at 1080p, indicating that its architecture is well-suited to Downfall at lower resolutions. The 8-pin power connector and 190 W TDP are consistent with a mid-range card that is capable, but not unlimited, in its performance headroom.

Measured FPS Breakdown

The measured FPS data provides a complete picture of performance across twelve different configurations. At 1920x1080, the results range from a high of 180.8 FPS on Low settings to a low of 80.1 FPS on Ultra. The Medium preset achieves 147.8 FPS, while High settings reach 124.5 FPS. This shows that at 1080p, the combo is capable of high-refresh-rate gaming even on the High preset.

At 2560x1440, the performance scales down predictably. The Low preset produces 130.9 FPS, which is still very high. Medium settings deliver 109.8 FPS, and High settings drop to 89.1 FPS. The Ultra preset is the only one that falls below the 60 FPS target, with an average of 53.3 FPS. This suggests that 1440p gaming is comfortable for most presets, but Ultra should be avoided for a smooth experience.

At 3840x2160, the GPU is clearly the limiting factor. The Low preset is the only one that provides a comfortable margin above 60 FPS, with an average of 80.1 FPS. The Medium preset hits 65.2 FPS, which is just above the threshold. However, High settings drop to 57.0 FPS, and Ultra settings plummet to 32.7 FPS. The data shows that 4K gaming with this combo requires a compromise on visual fidelity to maintain playable frame rates.

How This Combo Ranks

In the database of tested combinations, the AMD Ryzen 7 5800XT and Intel Arc B580 pair ranks 1360 out of 1741 combos for Downfall. This places it in the lower 22% of all tested systems, which is a surprising result given the strong 1080p performance. The ranking suggests that while the combo is capable, many other pairings deliver higher average frame rates across the board.

The rank is likely influenced by the 4K results, where the B580 struggles on higher settings. The combo’s position relative to other systems is not directly stated, but the rank implies that the majority of tested combos, which may include more powerful GPUs, achieve higher overall performance. The CPU’s percentile versus all CPUs is 86, indicating it is a strong processor, but the GPU’s percentile of 66 suggests it is a more mid-range component. This mismatch is reflected in the final ranking, where the GPU’s limitations at higher resolutions cap the overall performance of the system.

The data shows that this combo is a strong choice for 1080p and even 1440p gaming, but its ranking is dragged down by the demanding 4K results. For a system targeting high refresh rates at 1080p or a balanced 1440p experience, this pairing is effective. For 4K gaming, the data indicates that the user would need to significantly lower settings to achieve smooth gameplay, which is a trade-off that likely explains the lower rank among all tested combos.
