Downfall

# Downfall with AMD Ryzen 5 4600G + AMD Radeon RX 580

This pairing of the AMD Ryzen 5 4600G and AMD Radeon RX 580 produces a playable but constrained experience in Downfall, a 2016 horror title that scales predictably with resolution and settings. The data reveals a system where the GPU becomes the dominant bottleneck at higher resolutions, while the CPU's six cores and twelve threads provide sufficient headroom at 1080p. Across twelve measured configurations, the combo ranks 3395th out of 3716 tested combinations, placing it in the lower portion of the database — yet the raw frame rates tell a more nuanced story about where this hardware excels and where it collapses.

Resolution Scaling

The measured FPS data shows a steep, consistent drop as resolution increases from 1920x1080 to 3840x2160, a pattern that points squarely at the Radeon RX 580 as the limiting component. At Low settings, the average FPS falls from 102 at 1080p to 73 at 1440p — a decline of 28.4% — and then to 45 at 4K, which is 55.9% below the 1080p figure. This scaling is not linear; the 4K penalty is disproportionately severe, indicating that the GPU's memory bandwidth and pixel throughput are exhausted long before the CPU becomes relevant.

At Medium settings, the same trend emerges with slightly compressed margins: 83 FPS at 1080p, 60 at 1440p (a 27.7% drop), and 37 at 4K (a 55.4% drop from 1080p). The min FPS at Medium reveals additional strain — 71 at 1080p, 51 at 1440p, and 32 at 4K — which suggests that frame pacing degrades alongside average throughput. High settings follow the pattern: 68 FPS at 1080p, 49 at 1440p (27.9% lower), and 30 at 4K (55.9% lower). The consistency of these percentage drops across settings — all hovering near 28% for 1080p-to-1440p and 55% for 1080p-to-4K — strongly implies a single bottleneck that scales with pixel count rather than scene complexity.

Ultra settings, however, break the pattern with a more dramatic collapse: 43 FPS at 1080p, 31 at 1440p (27.9% drop), and 19 at 4K (55.8% drop). While the relative percentages remain similar, the absolute values plummet below playability thresholds at every resolution. This suggests that Ultra settings introduce additional shading or post-processing loads that the RX 580's 2304 shading units and 32 ROPs cannot sustain, even at 1080p. The data implies that resolution scaling is the primary lever here — dropping from 4K to 1080p at the same settings yields roughly a 2.27x improvement in average FPS across all presets, a factor that aligns with the pixel count difference of 4x being partially offset by other system efficiencies.

GPU Role

The AMD Radeon RX 580, built on the Polaris 20 chip with GCN 4.0 architecture, is the clear performance ceiling in this configuration. Its 8 GB of GDDR5 memory on a 256-bit bus delivers 256.0 GB/s of bandwidth, which becomes a critical resource at higher resolutions. The measured FPS data shows that at 4K, even Low settings only reach 45 FPS average — a figure that remains below the 60 FPS threshold often considered smooth — while Medium and High dip to 37 and 30 respectively. This indicates that memory bandwidth is likely saturated at 3840x2160, as the frame rate does not scale proportionally with the reduced shading load from Low to Medium settings.

The GPU's clock behavior — base 1257 MHz and boost 1340 MHz — appears modest by modern standards, and the 6.175 TFLOPS FP32 throughput (shared with FP16 at a 1:1 ratio) translates into a 53rd percentile ranking among all GPUs in the database. The nearest rivals, including the NVIDIA GeForce RTX 3050 Ti Mobile (deltaPct -0.1) and NVIDIA GeForce GTX 1660 SUPER (deltaPct -0.4), sit within 0.4% of the RX 580's average benchmark score of 12928, confirming that this GPU is competitive with mid-range parts from several generations. However, in Downfall specifically, the GPU's age shows: the 14 nm process node and 5,700 million transistors draw 185 W TDP, yet the 4K Ultra result of 19 FPS suggests that the architecture's fixed-function units cannot handle the game's heavier effects.

The VRAM capacity of 8 GB is not the limiting factor in these results, as even the lowest frame rates do not suggest texture thrashing. Instead, the combination of pixel rate (42.88 GPixel/s) and texture rate (193.0 GTexel/s) creates a ceiling that manifests at 1440p and above. At 1080p, the RX 580 manages 102 FPS on Low — a strong result that indicates the GPU is not fully utilized at lower pixel counts, leaving room for the CPU to drive performance. But at 4K, the GPU's 32 ROPs become the bottleneck, as evidenced by the 19 FPS Ultra result being less than half of the 43 FPS 1080p Ultra figure.

How This Combo Ranks

The combination of the AMD Ryzen 5 4600G and AMD Radeon RX 580 ranks 3395th out of 3716 tested combos in Downfall, placing it in the bottom 8.6% of the database. This rank is surprisingly low given the measured frame rates, which are playable at 1080p across most settings. The discrepancy suggests that the database includes many higher-end configurations that achieve far greater FPS in this horror title, or that the rank is influenced by the GPU's 53rd percentile and CPU's 71st percentile standings individually — neither of which is exceptional.

Breaking down the rank: the CPU's percentileVsAllCpus of 71 indicates it outperforms 71% of all processors in general benchmarks, while the GPU's percentileVsAllGpus of 53 places it barely above the median. The combination rank of 3395/3716 implies that most other tested combos have at least one component that significantly outperforms this pairing. The CPU's nearest rivals — AMD Ryzen 3 PRO 5355GE (deltaPct 0.1), AMD Ryzen 3 8300GE (deltaPct -0.6), and Intel Core 7 150U (deltaPct 0.6) — all score within 0.8% of the 4600G's average benchmark of 17507, suggesting that the CPU is not the weak link. Instead, the GPU's mid-pack standing, combined with the game's apparent sensitivity to GPU throughput, drags the combo down.

The rank implies that in a database of 3716 combos, this pairing is positioned for 1080p gaming rather than high-resolution play. The measured data supports this: at 4K, only Low settings approach 45 FPS, while at 1080p, Low achieves 102 FPS and Medium reaches 83. The rank of 3395 suggests that users seeking 60+ FPS at 1440p would need to look elsewhere, as this combo only hits 60 FPS at 1440p on Medium (exactly 60) and falls to 49 on High. The data indicates that the combo's placement is fair — it delivers entry-level 1080p performance but struggles beyond that.

Measured FPS Breakdown

At 1920x1080, the combo delivers its best results. Low settings produce an average of 102 FPS, which is the highest measured figure across all configurations. Medium settings reduce this to 83 FPS with a min of 71 and max of 96, indicating a stable frame delivery. High settings drop to 68 FPS, still comfortably above 60. Ultra settings, however, fall to 43 FPS — a substantial 57.8% reduction from Low, suggesting that Ultra's additional effects (likely shadows, reflections, or ambient occlusion) overwhelm the RX 580's capabilities. The spread from Low to Ultra at 1080p is 59 FPS, which is the largest absolute gap across any resolution.

At 2560x1440, the results become more constrained. Low settings average 73 FPS, which is playable but no longer silky smooth. Medium settings hit exactly 60 FPS average, with a min of 51 and max of 69 — the variance of 18 FPS indicates that scenes with heavy particle effects or multiple enemies cause noticeable dips. High settings fall to 49 FPS, which is below the 60 FPS target for many players. Ultra settings drop to 31 FPS, which is marginal for a horror game where responsiveness matters. The 1440p data shows a consistent 28% reduction from 1080p across all settings, confirming that resolution is the primary scaling factor.

At 3840x2160, the results are uniformly below playability thresholds. Low settings manage 45 FPS average, which is technically playable but with noticeable stutter during intense moments. Medium settings drop to 37 FPS with a min of 32 and max of 43, indicating that the GPU is struggling to maintain even moderate frame pacing. High settings fall to 30 FPS, which is the bare minimum for console-like performance. Ultra settings collapse to 19 FPS, which is effectively unplayable for a game requiring quick reactions. The 4K data shows that this combo is not viable beyond 1440p, and even at 1440p, only Low and Medium settings provide acceptable frame rates.

CPU Role

The AMD Ryzen 5 4600G, based on Zen 2 architecture with the Renoir codename, provides six cores and twelve threads running at a base clock of 3.70 GHz and boost clock of 4.20 GHz. This CPU is a 65 W part built on TSMC's 7 nm process, featuring 9,800 million transistors on a 156 mm² die. Its cache hierarchy includes 64 KB L1 per core, 512 KB L2 per core, and 8 MB shared L3, which is modest by modern standards but sufficient for a 2016 horror game. The CPU's 3dmark scores — 726 single-thread, 1430 for 2 threads, 2732 for 4 threads, 4138 for 8 threads, and 4889 for max threads — show that multi-threaded scaling is strong, with the max-thread score being 6.7x the single-thread score.

In Downfall, the CPU's role appears secondary to the GPU. The measured FPS data shows that at 1080p Low, the combo reaches 102 FPS, which is likely near the CPU's practical limit for frame generation in this title. The 3dmark 2-thread score of 1430 and 4-thread score of 2732 indicate that the CPU can handle the game's main thread plus a few helper threads, but the game's age (released 2016-02-28) means it likely doesn't utilize all 12 threads effectively. The Cinebench R23 multicore score of 13593 and single-core score of 1919 further confirm that the CPU has ample headroom for gaming workloads.

The CPU's memory support for DDR4 with dual-channel configuration and 51.2 GB/s bandwidth (memory bandwidth field) is adequate for this GPU pairing, as the RX 580's 256.0 GB/s bandwidth is not starved by the CPU's memory throughput. The CPU's PCIe Gen 3 with 20 lanes (CPU only) provides sufficient bandwidth for the GPU's PCIe 3.0 x16 interface. The integrated Radeon Vega 7 graphics are irrelevant here since a discrete GPU is installed, but they do not appear to interfere with performance. The CPU's percentileVsAllCpus of 71 and avgBenchmarkScore of 17507 place it well above the median, and its nearest rivals all score within 0.8%, confirming that the 4600G is a solid mid-range processor that does not hold back the RX 580 in this game.

Settings Recommendations

The measured FPS data provides a clear hierarchy for optimal settings in Downfall. At 1920x1080, Medium settings deliver an average of 83 FPS with a min of 71 and max of 96 — this is the sweet spot for the combo, offering a 21.7% improvement over High (68 FPS) while maintaining a minimum above 70, which is critical for a horror game where sudden frame drops can break immersion. Low settings push to 102 FPS but the visual quality loss is likely not worth the extra 19 FPS, especially since Medium already exceeds the 60 FPS threshold by a wide margin. High settings at 68 FPS are acceptable but leave little headroom for demanding scenes, and Ultra at 43 FPS is too inconsistent for smooth gameplay.

At 2560x1440, Medium settings average exactly 60 FPS with a min of 51, which is the only preset that hits the 60 FPS target at this resolution. Low settings at 73 FPS are smoother but sacrifice too much visual fidelity for a horror game that relies on atmosphere. High settings at 49 FPS are below the 60 FPS threshold, and Ultra at 31 FPS is unplayable. For 1440p users, Medium is the recommended preset, though the min FPS of 51 suggests occasional dips below 60 that may be noticeable during intense sequences.

At 3840x2160, no settings preset provides a consistently playable experience. Low settings at 45 FPS are the best option, but the frame rate is below 60 and likely to feel stuttery. Medium at 37 FPS and High at 30 FPS are marginal at best, while Ultra at 19 FPS is completely unplayable. The data strongly recommends avoiding 4K with this combo, as even the lowest settings cannot maintain smooth performance. For the best overall experience, the 1080p Medium preset offers the optimal balance of frame rate (83 FPS average), stability (71 FPS minimum), and visual quality, making it the clear choice for this hardware pairing in Downfall.
