Downfall

# Downfall with AMD Ryzen 5 4600G + Intel Arc B580

The AMD Ryzen 5 4600G paired with the Intel Arc B580 produces a fascinating set of results in Downfall, a 2016 horror title that clearly responds well to modern hardware. This combination ranks 2802 out of 3716 tested combos, placing it in the lower-middle tier of the database, yet the measured frame rates tell a more nuanced story than that raw ranking suggests. The data reveals a system that can handle 1080p and 1440p gaming comfortably, but struggles to maintain smooth performance at 4K Ultra settings, indicating a balanced yet ultimately limited partnership between the six-core Zen 2 processor and the Battlemage GPU.

Resolution Scaling

The FPS drop from 1080p to 4K is dramatic and reveals where the bottleneck shifts across the resolution spectrum. At High settings, the average frame rate falls from 124 FPS at 1920x1080 to 88 FPS at 2560x1440 — a 29% reduction — and then further to 55 FPS at 3840x2160, representing a 56% drop from the 1080p baseline. This scaling pattern suggests that at 1080p, the system is not fully GPU-limited; the Arc B580 has headroom that the Ryzen 5 4600G cannot fully exploit, while at 4K the GPU becomes the clear limiting factor.

The Low settings row reinforces this interpretation. At 1080p Low, the system produces 185 FPS, but this falls to 132 FPS at 1440p and 82 FPS at 4K. The percentage drops between resolutions are 29% and 38% respectively, which is actually a shallower decline at the top end than what High settings show. This indicates that when the CPU has less work to do per frame (due to lower graphical complexity), it can feed the GPU more effectively, but the GPU still dominates the performance ceiling at higher resolutions.

Medium settings provide the most complete data set, with min and max FPS recorded at every resolution. At 1080p, the range is 128-174 FPS with an average of 151. At 1440p, this drops to 92-124 FPS averaging 108. At 4K, the range narrows to 57-77 FPS with an average of 67. The narrowing range at higher resolutions suggests that frame pacing becomes more consistent as the GPU becomes the sole bottleneck, whereas at 1080p the CPU can introduce more variance. The Ultra preset shows the steepest decline: 77 FPS at 1080p, 55 FPS at 1440p, and just 34 FPS at 4K — a 56% loss from 1080p to 4K, exactly matching the High preset's proportional drop.

Settings Recommendations

The measured data offers clear guidance for players seeking the best experience across resolutions. At 1920x1080, the Medium preset delivers 151 FPS average with a minimum of 128 FPS, which comfortably exceeds the 60 FPS target for smooth gameplay. The High preset at 124 FPS average is also viable, but the jump to Ultra at 77 FPS costs nearly half the frame rate for what is likely marginal visual improvement in a horror title where atmosphere matters more than fine detail. The Low preset at 185 FPS is only useful for competitive play or for users with very high refresh rate monitors.

For 2560x1440, Medium at 108 FPS average and 92 FPS minimum is the sweet spot, providing a solid experience that stays above 60 FPS even in the worst-case measured frames. High at 88 FPS average is also acceptable, but the minimum frame rate is not recorded, introducing uncertainty about potential dips. Ultra at 55 FPS average falls below the 60 FPS threshold and should be avoided unless the player accepts occasional stutter. Low at 132 FPS is unnecessary unless chasing maximum frame rates.

At 3840x2160, the situation becomes more constrained. Medium at 67 FPS average with a 57 FPS minimum is the only preset that consistently stays near 60 FPS, making it the recommended choice for 4K displays. High at 55 FPS is borderline, and Ultra at 34 FPS is effectively unplayable for a smooth experience. Low at 82 FPS is surprisingly playable, but the visual quality trade-off in a horror game that relies on atmosphere and lighting makes Medium the better overall recommendation.

GPU Role

The Intel Arc B580 brings substantial resources to this pairing: 12 GB of GDDR6 memory on a 192-bit bus, delivering 456.0 GB/s of bandwidth. The GPU runs at a fixed 2670 MHz for both base and boost clocks, with memory at 2375 MHz (19 Gbps effective). This memory configuration is more than sufficient for Downfall, which released in 2016 and would have been designed around much smaller VRAM pools. The 12 GB capacity means that even at 4K Ultra, the game is unlikely to hit memory limits — the measured 34 FPS at that setting is a compute or fill-rate limitation, not a VRAM constraint.

The GPU's architecture, Xe2-HPG on TSMC's 5 nm process, includes 2560 shading units, 160 TMUs, and 80 ROPs. The pixel rate of 213.6 GPixel/s and texture rate of 427.2 GTexel/s help explain the scaling pattern: at 4K, the GPU must fill over 8 million pixels per frame, and the 34 FPS at Ultra suggests the ROP throughput is the limiting factor. The FP32 compute of 13.67 TFLOPS provides ample shader power for a 2016 title, but the fixed 2670 MHz clock means there is no boost headroom to compensate when the load increases.

The GPU's benchmark scores position it well relative to its rivals. Its avgBenchmarkScore of 23021 places it just 0.2% behind the AMD Radeon RX 580 2048SP and 0.6% ahead of the NVIDIA GeForce RTX 2080, while sitting 0.7% below the RTX 3080. This clustering suggests the B580 performs at a level comparable to much older high-end cards, which is consistent with the measured FPS in Downfall — the game is not demanding enough to expose significant differences between these GPUs. The passmark G3D score of 15748 further confirms this mid-range positioning.

Measured FPS Breakdown

At 1920x1080, the full settings sweep shows a clear hierarchy: Low produces 185 FPS average, Medium 151 FPS (128-174 range), High 124 FPS, and Ultra 77 FPS. The gap between Medium and High is 27 FPS, while the gap between High and Ultra is 47 FPS, indicating that the Ultra preset introduces disproportionately heavy effects that tax the GPU. The Medium preset's minimum of 128 FPS is higher than the High preset's average, which suggests that the visual features removed when dropping from High to Medium are particularly expensive.

Moving to 2560x1440, the averages are 132 FPS for Low, 108 FPS for Medium (92-124 range), 88 FPS for High, and 55 FPS for Ultra. The Medium preset's minimum of 92 FPS is still well above the 60 FPS threshold, making it the safest choice for consistent performance at this resolution. The High preset's 88 FPS average is playable, but without min/max data, there is some risk of dips below 60 FPS. Ultra at 55 FPS average is marginal, and the lack of min/max data means the worst-case scenario could be significantly lower.

At 3840x2160, the averages are 82 FPS for Low, 67 FPS for Medium (57-77 range), 55 FPS for High, and 34 FPS for Ultra. The Medium preset's minimum of 57 FPS is just below the 60 FPS target, so players with adaptive sync displays would likely have a satisfactory experience, but those without could notice occasional stutter. The Low preset at 82 FPS is the only option that provides comfortable headroom above 60 FPS, but it sacrifices the visual fidelity that makes a horror game immersive. The Ultra preset at 34 FPS is only suitable for screenshots or slide shows.

How This Combo Ranks

The combo rank of 2802 out of 3716 places this pairing in the 75th percentile of tested combinations — meaning roughly 75% of configurations outperform it in this game. This ranking is somewhat surprising given the strong 1080p and 1440p results, but it reflects the fact that Downfall is an older title where many modern mid-range and high-end systems can achieve very high frame rates. The 1000-combo gap between this pairing and the top of the database suggests that the Ryzen 5 4600G's single-thread performance (3dmark_single_thread score of 726, passmark_single_thread of 2653) holds back the Arc B580 in CPU-bound scenarios.

The CPU's percentileVsAllCpus of 71 indicates it outperforms 71% of all CPUs in the database, while the GPU's percentileVsAllGpus of 68 shows similar positioning. This alignment means neither component is dramatically stronger than the other, resulting in a balanced system that performs as expected for its component tier. The CPU's nearest rivals — the AMD Ryzen 3 PRO 5355GE at 0.1% higher avgScore, the AMD Ryzen 3 8300GE at 0.6% lower, the Intel Core 7 150U at 0.6% higher, and the Intel Core i3-14100T at 0.8% lower — all cluster within 1% of each other, indicating that the 4600G sits in a tightly competitive segment.

The GPU's nearest rivals show similar clustering: the RX 580 2048SP is 0.2% higher, the RTX 2080 is 0.6% lower, the RTX 3080 is 0.7% higher, and the P106-100 is 1% lower. This grouping of very different generations and tiers of GPUs within 1% of each other suggests that the benchmark average used for ranking does not fully capture gaming performance differences, which the measured FPS in Downfall confirms — the game runs well on this hardware despite the mid-pack ranking.

FAQ

Q: Can this system run Downfall at 60 FPS on a 4K display?

Q: Is the Ryzen 5 4600G holding back the Intel Arc B580 in Downfall?

A: At 1080p Low and Medium settings, the CPU likely limits performance, as the GPU has enough headroom to produce very high frame rates. At 4K, the GPU becomes the clear bottleneck, as evidenced by the steep FPS drops at higher resolutions.

CPU Role

The AMD Ryzen 5 4600G provides six cores and twelve threads based on the Zen 2 architecture, running at a base clock of 3.70 GHz and boosting to 4.20 GHz. This 4000 series processor, built on TSMC's 7 nm process, includes 8 MB of shared L3 cache and supports dual-channel DDR4 memory with 51.2 GB/s bandwidth. The CPU's 65 W TDP and AM4 socket compatibility make it a modest but capable pairing for the Arc B580, which has a 190 W TDP and requires a 450 W power supply.

The CPU's benchmark results show a clear strength in multi-threaded workloads: cinebench_r23_multicore scores 13593, while the single-core score is 1919. The passmark_multithread score of 15992 versus passmark_single_thread of 2653 further illustrates this disparity. In Downfall, a game from 2016, the single-thread performance is likely more important, as older titles typically do not scale well across many cores. The 3dmark_single_thread score of 726 places the CPU in a moderate range, and the nearest rivals — all within 1% in avgScore — suggest that the 4600G is competitive with other budget and mid-range processors.

The CPU's 3.70 GHz base clock and 4.20 GHz boost clock provide reasonable frequency for gaming, but the Zen 2 architecture's IPC (instructions per clock) is lower than newer designs. The L3 cache of 8 MB is modest by modern standards, and this could impact performance in games that rely on frequent cache hits. The 3dmark_16_threads score of 4863 and max_threads score of 4889 are nearly identical, indicating that the CPU reaches its performance plateau with the available threads, which aligns with a six-core design handling the game's workload efficiently.

The CPU's percentileVsAllCpus of 71 and the GPU's percentileVsAllGpus of 68 show that these components are well-matched in relative performance. In Downfall, the data suggests that at 1080p, the CPU can push frame rates high enough to expose the GPU's limits, while at 4K the GPU's rendering demands dominate. The 2016 release date of the game means it predates many modern CPU optimizations, so the 4600G's single-thread performance is the primary factor in CPU-bound scenarios, and the measured FPS at Low settings (185 at 1080p) indicates the CPU can handle the game's logic without becoming a severe bottleneck.
