Downfall

The AMD Ryzen 5 5600GT paired with the Intel Arc B580 delivers a playable experience in Downfall, but the data reveals a steep performance cliff at higher resolutions. At 1080p, the system is clearly capable of high refresh rates, yet the transition to 4K shows significant scaling losses that shift the bottleneck firmly onto the GPU. The measured FPS figures indicate a balanced 1080p setup that becomes GPU-bound as pixel count increases.

Resolution Scaling

The performance drop from 1080p to 4K is dramatic and defines the character of this combo. At High settings, the average frame rate falls from 124 FPS at 1920x1080 to 88 FPS at 2560x1440, then plummets to 55 FPS at 3840x2160. That represents a 55.6% reduction in performance from 1080p to 4K, which is a clear indicator that the Intel Arc B580 is the limiting component at higher resolutions. The scaling from 1440p to 4K is particularly steep, with a 37.5% drop, suggesting the GPU's memory bandwidth and raw compute are being saturated.

The Low preset shows a similar pattern. At 1080p, the combo achieves 185 FPS, which drops to 132 FPS at 1440p (a 28.6% decrease) and further to 82 FPS at 4K (a 37.9% decrease from 1440p). The fact that even the lowest settings cannot maintain 100+ FPS at 4K confirms that the GPU, not the CPU, is the primary constraint. The Ryzen 5 5600GT, with its 6 cores and 12 threads, has enough headroom at lower resolutions where the frame rates are higher, but the Arc B580's 12 GB of GDDR6 memory and 456.0 GB/s bandwidth are insufficient to keep pace with the pixel workload at 4K.

The Medium preset data reinforces this conclusion. At 1080p, the average is 151 FPS, dropping to 108 FPS at 1440p and 67 FPS at 4K. The percentage drop from 1080p to 4K is 55.6%, nearly identical to the High preset's scaling. This consistency suggests that resolution scaling is independent of the quality preset — the GPU's performance ceiling is being hit regardless of how much work is being offloaded. The Ultra preset shows the most severe scaling: from 77 FPS at 1080p to 55 FPS at 1440p (a 28.6% drop) and then to 34 FPS at 4K (a 38.2% drop). The 4K Ultra figure of 34 FPS is barely playable, and the scaling curve indicates that the Arc B580 is overwhelmed by the combination of high pixel count and maximum graphical fidelity.

The data shows that the Ryzen 5 5600GT is not the limiting factor in this game. At 1080p Low, the CPU can drive 185 FPS, which is well above the 60 FPS target. The CPU's single-thread score of 913 in 3dmark and its Cinebench R23 single-core score of 2438 indicate sufficient per-core performance for a horror title like Downfall, which typically relies on fewer threads. The bottleneck is the GPU's rendering throughput, which is taxed heavily as resolution increases.

GPU Role

The Intel Arc B580's specifications explain the observed performance curve. With a base and boost clock of 2670 MHz, the GPU is running at a consistent frequency across all tests. The 12 GB of GDDR6 memory on a 192-bit bus provides 456.0 GB/s of bandwidth, which is a substantial figure but appears insufficient for 4K textures and effects in this title. The measured FPS at 4K Ultra (34 FPS) suggests that the memory bandwidth is being saturated, as the GPU also has 2560 shading units and 80 ROPs to feed.

The GPU's VRAM capacity is not the issue at 1080p or 1440p, where the High preset delivers 124 FPS and 88 FPS respectively. However, at 4K, the combination of higher resolution textures and additional post-processing effects likely exceeds the effective memory bandwidth, causing the frame rate to collapse. The Arc B580's 20 ray tracing cores are present, but Downfall as a 2016 horror title likely does not utilize them heavily, meaning the standard rasterization pipeline is the primary workload.

The GPU's benchmark scores place it in a specific performance tier. Its Passmark G3D score of 15748 and 3DMark Steel Nomad score of 3068 indicate mid-range performance. The nearest rival data shows it is roughly on par with the NVIDIA GeForce RTX 2080, which has a deltaPct of 0.6% (meaning the Arc B580 is 0.6% ahead). This contextualizes the 4K results: the system is performing as expected for a GPU in this class, which is not designed for maxed-out 4K gaming. The GPU's percentile ranking of 68 versus all GPUs confirms it is above average but not top-tier.

The clock behavior is stable, with the base and boost clocks identical at 2670 MHz. This suggests the GPU is not thermally throttling and is running at its maximum potential. The memory clock of 2375 MHz (19 Gbps effective) is also consistent, meaning the performance drops are due to workload saturation rather than clock variability. The GPU's 13.67 TFLOPS FP32 performance is the theoretical ceiling, and the measured FPS data shows the card approaching that ceiling at 1080p Low (185 FPS) but falling well short at 4K Ultra (34 FPS).

Settings Recommendations

The measured data provides clear guidance on the optimal settings for different resolutions. At 1080p, the High preset is the sweet spot, delivering 124 FPS. This is well above the 60 FPS threshold and leaves headroom for drops during intense horror sequences. The Ultra preset at 77 FPS is also playable, but the 47 FPS difference between High and Ultra suggests diminishing returns for the extra visual fidelity. For players with 144Hz monitors, the Low preset's 185 FPS is optimal, but the visual quality trade-off is significant. The Medium preset at 151 FPS offers a balanced compromise for high refresh rate displays.

At 1440p, the High preset at 88 FPS is the recommended choice. It is above 60 FPS and provides good visual quality. The Medium preset at 108 FPS is also viable for those prioritizing frame rate, but the jump from Medium to High only costs 20 FPS (108 to 88) while likely offering noticeable visual improvements. The Ultra preset at 55 FPS is borderline, dipping below the 60 FPS ideal, and the Low preset at 132 FPS sacrifices too much visual fidelity for the frame rate gain.

At 4K, the situation is more constrained. The Medium preset at 67 FPS is the only setting that achieves a playable frame rate above 60 FPS. The High preset at 55 FPS is playable but may feel inconsistent during action sequences. The Low preset at 82 FPS is the highest frame rate available at 4K, but the visual quality will be noticeably reduced. The Ultra preset at 34 FPS is not recommended for anything other than screenshots, as it falls below the threshold for smooth gameplay.

The data suggests that the best overall experience is 1080p High for most users, as it provides 124 FPS with solid visual quality. For 1440p users, High is the best balance of performance and fidelity. For 4K users, Medium is the only viable option that maintains playability, albeit with a reduced visual experience compared to lower resolutions.

How This Combo Ranks

The AMD Ryzen 5 5600GT + Intel Arc B580 combo ranks 2802 out of 3716 tested combinations in Downfall. This places it in the 75th percentile, meaning it outperforms roughly three-quarters of all tested systems. Given the GPU's percentile ranking of 68 versus all GPUs and the CPU's percentile ranking of 74 versus all CPUs, this combo ranking aligns with the individual component performance.

The CPU's nearest rivals provide context for its contribution. The Ryzen 5 5600GT has an average benchmark score of 20733, which is nearly identical to the Intel Core i5-12490F (20802, deltaPct -0.3%). This means the CPU is performing at a level comparable to a mid-range Intel chip from a newer generation. The CPU's Cinebench R23 multicore score of 17272 and single-core score of 2438 indicate it is a capable processor for gaming, though not a top-tier contender.

The GPU's nearest rivals show a mixed comparison. The Arc B580's average benchmark score of 23021 is within 1% of the AMD Radeon RX 580 2048SP (23061, deltaPct -0.2%), the NVIDIA GeForce RTX 2080 (22895, deltaPct 0.6%), and the NVIDIA GeForce RTX 3080 (23172, deltaPct -0.7%). This is notable because the RTX 3080 is typically considered a high-end card, yet the Arc B580 matches it in synthetic benchmarks. However, in Downfall specifically, the combo's rank of 2802 suggests that real-world gaming performance may differ from synthetic scores.

The rank of 2802 out of 3716 indicates that while this combo is not a top performer, it is also not a low-end pairing. It sits comfortably in the upper-middle tier of tested systems. The bottleneck is clearly the GPU, as evidenced by the resolution scaling data. If the CPU were the limiting factor, we would expect to see smaller FPS drops at higher resolutions, but the 55.6% reduction from 1080p to 4K proves the GPU is the constraint.
