Downfall

The AMD Ryzen 5 5600 paired with the NVIDIA GeForce RTX 5090 D places this combo at rank 67 out of 2,928 tested combinations in Downfall. This position in the 97th percentile of tested combos indicates that, while the graphics card is a top-tier part, the pairing is not the absolute fastest configuration for this specific horror title. The data suggests the CPU is a limiting factor in extracting the absolute maximum frame rate from the RTX 5090 D, yet the combination still delivers an exceptionally high-performance experience that outperforms the vast majority of other systems.

How This Combo Ranks

The combo’s rank of 67 out of 2,928 tested combos places it in the top 2.3% of all pairings tested for Downfall. This is a dominant position, but the gap between this rank and the number one spot is telling. The RTX 5090 D itself holds a 92nd percentile ranking among all GPUs, and its average benchmark score of 77,712 puts it 1.1% ahead of the AMD Radeon RX 6650M XT, yet 1.6% behind the AMD Radeon RX 6850M XT. This suggests that while the GPU is potent, its performance edge is not as overwhelming as its raw specs might imply.

The Ryzen 5 5600’s percentile ranking of 74 among all CPUs, with an average benchmark score of 20,468, is respectable but not elite. It sits within 0.1% of the Intel Core Ultra 7 258V and 0.2% of the AMD Ryzen 5 8500G and AMD EPYC 9454P. For a 6-core, 12-thread processor, this is a solid result, but it falls short of the top-tier CPUs that can feed a flagship GPU like the RTX 5090 D at lower resolutions. The data indicates that the 67th rank is a direct consequence of this CPU-GPU balance, where the GPU is capable of much higher frame rates than the CPU can consistently deliver in Downfall.

Settings Recommendations

Benchmark results show that the Ultra preset is the most demanding, with the highest visual fidelity but a significant performance cost. At 1080p, the Ultra preset delivers 202 FPS, while the High preset reduces the load and produces 316 FPS. The Medium preset, however, offers a more balanced experience at 339 FPS with a minimum of 288 FPS and a maximum of 390 FPS. For players with high-refresh-rate 1080p displays, the Medium preset appears to be the sweet spot, as it provides a substantial frame rate increase over High with only a minor visual quality reduction.

At 1440p, the Medium preset continues to shine with 282 FPS (minimum 240, maximum 324), which is 51 FPS higher than the High preset’s 231 FPS. The Ultra preset at 1440p drops to 144 FPS, which is still playable but represents a significant downgrade from Medium. The Low preset at 1440p produces 325 FPS, but the visual degradation in a horror game can harm atmosphere and readability. For 4K gaming, the Medium preset is the most practical choice, delivering 175 FPS with a minimum of 149 FPS and a maximum of 202 FPS. The High preset at 4K drops to 144 FPS, which is borderline for a smooth experience. The Ultra preset at 4K is the least viable, falling to 90 FPS.

Given the data, the Medium preset provides the best overall experience across all resolutions. It maintains frame rates well above 144 FPS at 1080p and 1440p, and it remains above 170 FPS at 4K. The Low preset offers higher frame rates, but the Medium preset’s balance of visual quality and performance is more appropriate for a game that relies on atmosphere and lighting.

Resolution Scaling

The FPS scaling from 1080p to 4K reveals a clear trend: the RTX 5090 D is not the primary bottleneck at lower resolutions. At 1080p with Medium settings, the average FPS is 339. Dropping to 1440p Medium reduces this to 282 FPS, a 16.8% decrease. Moving from 1440p to 4K Medium brings the frame rate to 175 FPS, a 37.9% decrease. This pattern shows that as resolution increases, the frame rate drops are not linear, indicating that the CPU is limiting performance at 1080p.

At 1080p, the CPU cannot feed the GPU enough frames to saturate its capability, as evidenced by the relatively small FPS gap between Low (364 FPS) and Medium (339 FPS) settings. The difference between 1080p Low and 1440p Low is 39 FPS (from 364 to 325), while the difference between 1440p Low and 4K Low is 111 FPS (from 325 to 214). This suggests that the GPU becomes more of a limiting factor as resolution scales up, particularly at 4K where the pixel throughput demands more from the RTX 5090 D.

The data also shows that the CPU is a significant constraint in Downfall. At 1080p Ultra, the frame rate is 202 FPS, which is higher than 4K High’s 144 FPS but lower than 1440p High’s 231 FPS. This indicates that the game’s engine is not purely GPU-bound at high settings; the Ryzen 5 5600’s single-threaded performance, with a Cinebench R23 single-core score of 2,584 and a 3DMark single-thread score of 882, plays a role in the overall frame delivery.

Measured FPS Breakdown

1920x1080:

• Low: 364 FPS average.
• Medium: 339 FPS average, with a minimum of 288 FPS and a maximum of 390 FPS.
• High: 316 FPS average.
• Ultra: 202 FPS average.

2560x1440:

• Low: 325 FPS average.
• Medium: 282 FPS average, with a minimum of 240 FPS and a maximum of 324 FPS.
• High: 231 FPS average.
• Ultra: 144 FPS average.

3840x2160:

• Low: 214 FPS average.
• Medium: 175 FPS average, with a minimum of 149 FPS and a maximum of 202 FPS.
• High: 144 FPS average.
• Ultra: 90 FPS average.

The 1080p data shows a clear plateau between Low and Medium settings, with only a 25 FPS difference. This indicates that the CPU is the limiting factor at this resolution, as the GPU can handle the increased load of Medium settings without a proportional frame rate drop. The jump from Medium to High results in a 23 FPS drop, while High to Ultra is a 114 FPS drop, showing that Ultra settings introduce a substantial GPU workload.

At 1440p, the gap between Low and Medium narrows to 43 FPS, and the gap between Medium and High is 51 FPS. The Ultra preset at 1440p produces 144 FPS, which is the same as the 4K High preset. This coincidence suggests that the Ultra preset at 1440p and High preset at 4K have similar GPU demands, but the CPU’s influence is still visible in the frame rate stability.

At 4K, the Low to Medium gap is 39 FPS, and the Medium to High gap is 31 FPS. The Ultra preset at 4K drops to 90 FPS, which is a 50% reduction from High. This shows that the GPU is heavily taxed at 4K Ultra, and the CPU is less of a factor. The RTX 5090 D’s 32 GB of GDDR7 memory and 1.79 TB/s bandwidth are sufficient for these loads, but the frame rates indicate a performance ceiling that is not fully explained by the GPU’s raw compute power.

Q: Is the CPU’s multi-threaded performance relevant for this game?

A: The Ryzen 5 5600 has a Cinebench R23 multicore score of 18,309 and a 3DMark max-thread score of 5,659. While Downfall shows CPU sensitivity at lower resolutions, the game does not appear to be heavily multi-threaded, as the 6-core/12-thread configuration is sufficient to maintain high frame rates without excessive core scaling.

CPU Role

The AMD Ryzen 5 5600 is a 6-core, 12-thread processor based on the Zen 3 architecture, codenamed Vermeer. It has a base clock of 3.50 GHz and a boost clock of 4.40 GHz, with a 65 W TDP. The CPU’s cache hierarchy includes 64 KB of L1 per core, 512 KB of L2 per core, and 32 MB of shared L3 cache. This configuration is typical for a mid-range desktop processor, and its benchmark scores reflect a balanced single-threaded and multi-threaded performer.

In Downfall, the CPU’s single-threaded performance is critical. The 3DMark single-thread score of 882 and Cinebench R23 single-core score of 2,584 are the key metrics that determine how well the CPU can feed the GPU at high frame rates. The data shows that at 1080p, the FPS is capped at around 364 FPS on Low settings, which is likely near the CPU’s limit for this game’s engine. The multi-threaded scores, such as the 3DMark 16-thread score of 5,641 and the Passmark multithread score of 21,541, are less relevant because Downfall does not appear to scale well with additional cores beyond the 6 cores available.

The 7 nm process node and 4,150 million transistors are part of the CPU’s design, but they do not directly translate to game performance. The CPU’s 32 MB of L3 cache is beneficial for gaming, as it reduces memory latency, but the 51.2 GB/s memory bandwidth is a limiting factor for a flagship GPU. The PCIe Gen 4 interface with 20 lanes provides sufficient bandwidth for the RTX 5090 D, which uses PCIe 5.0 x16, but the CPU’s support is only Gen 4. This does not appear to be a major issue in the measured results, as the frame rates are high across all resolutions.

The Ryzen 5 5600’s performance is adequate for this GPU, but the rank of 67 indicates that a more powerful CPU would yield higher frame rates, especially at 1080p where the CPU is the main bottleneck. The CPU’s TDP of 65 W is low, which is good for thermals, but its boost clock of 4.40 GHz is modest compared to more expensive processors. The data suggests that for Downfall, the CPU is a limiting factor at lower resolutions, but at 4K, the GPU’s workload dominates and the CPU’s role diminishes.
