Downfall

Resolution Scaling

The measured frame rates for Downfall with the AMD Ryzen 7 5700 and AMD Radeon RX 7800 XT show a clear progression as resolution increases. At 1920x1080 with Ultra settings, the combo produces 120.7 FPS average. Moving to 2560x1440 drops that to 86.9 FPS, a reduction of roughly 28%. The step to 3840x2160 brings the average down to 50.5 FPS, which is a further 42% decline from the 1440p result. This scaling pattern indicates that the GPU is becoming the primary limiting factor as pixel count rises.

The Low settings row tells a similar story. At 1080p Low, the system achieves 282 FPS average. At 1440p Low, that falls to 200.8 FPS, and at 4K Low it reaches 124.2 FPS. The percentage drops are consistent with what the Ultra row shows, suggesting the rendering workload scales predictably with resolution. The 4K Low result being higher than the 1080p Ultra result — 124.2 versus 120.7 FPS — is notable because it demonstrates that settings have a larger impact on performance than resolution alone in this horror title.

The spread between Low and Ultra at each resolution reveals where the bottleneck sits. At 1080p, the gap between Low (282 FPS) and Ultra (120.7 FPS) is 161.3 FPS, a massive range that points to the GPU being heavily loaded by the higher-quality presets. At 4K, the same Low-to-Ultra gap narrows to 73.7 FPS (124.2 versus 50.5). The shrinking absolute difference at higher resolutions indicates that the GPU is saturated earlier in the 4K tier, while at 1080p the CPU has more headroom to push frame rates upward when settings are reduced.

GPU Role

The AMD Radeon RX 7800 XT carries 16 GB of GDDR6 memory on a 256-bit bus, providing 624.1 GB/s of bandwidth. This memory configuration is substantial for a horror game like Downfall, which benefits from large texture pools and high-resolution assets. The 3840 shading units and 96 ROPs deliver the raw throughput needed for the measured frame rates. The GPU's boost clock of 2430 MHz and game clock of 2124 MHz are the operating frequencies that produce these results, with a base clock of 1295 MHz as the floor.

The data shows that the RX 7800 XT is capable of handling 4K Ultra at 50.5 FPS average, which is playable but not smooth for a genre that often relies on atmospheric tension. At 4K High, the average improves to 84.1 FPS, a 33.6 FPS jump that suggests the Ultra preset's additional effects are disproportionately expensive. The GPU's 76th percentile ranking among all GPUs places it above most tested hardware, and its average benchmark score of 32619 is competitive with the nearest rivals listed — the AMD FirePro S9300 X2 trails by 0.2%, while the NVIDIA P104-100 leads by 0.4%.

The VRAM capacity becomes relevant when examining the 4K results. With 16 GB available, the card does not appear to be memory-limited at any settings tier in this game. The 50.5 FPS at 4K Ultra is more likely a compute or bandwidth constraint than a capacity issue. The 624.1 GB/s memory bandwidth is sufficient for the pixel rates being pushed, but the 233.3 GPixel/s pixel rate and 583.2 GTexel/s texture rate are the specs that ultimately define the ceiling.

Settings Recommendations

For 1080p displays, the Ultra preset at 120.7 FPS average is the best choice for this combo. The game remains well above 60 FPS while delivering the maximum visual quality, and the GPU has enough headroom that frame drops would be minimal. The Medium preset at 229.4 FPS is overkill for most displays, and the Low preset at 282 FPS offers no practical benefit unless the user has a very high refresh rate monitor.

At 1440p, the High preset at 133.9 FPS is the optimal balance. It stays comfortably above 120 FPS, which suits high-refresh displays, while the Ultra preset at 86.9 FPS still provides a smooth experience but sacrifices some fluidity. The Medium preset at 165.9 FPS is a viable alternative for competitive play, but the visual difference from High is not worth the frame rate gain for a single-player horror title.

For 4K, the High preset at 84.1 FPS is the recommended setting. The Ultra preset at 50.5 FPS dips below the 60 FPS threshold, which can feel stuttery in a game that relies on smooth camera movement for its horror effect. The Medium preset at 100.4 FPS is also acceptable, but High offers better image quality with only a 16.3 FPS penalty compared to Medium. The Low preset at 124.2 FPS is unnecessary at this resolution, as the visual degradation would undermine the immersion that 4K is meant to provide.

Measured FPS Breakdown

At 1920x1080, the measured averages are as follows: Low settings produce 282 FPS, Medium produces 229.4 FPS, High produces 186.5 FPS, and Ultra produces 120.7 FPS. The scaling from Low to Ultra is nonlinear — dropping from Low to Medium costs 52.6 FPS, from Medium to High costs 42.9 FPS, and from High to Ultra costs 65.8 FPS. The largest single-step penalty occurs between High and Ultra, indicating that the Ultra preset includes particularly demanding effects.

At 2560x1440, the averages are: Low at 200.8 FPS, Medium at 165.9 FPS, High at 133.9 FPS, and Ultra at 86.9 FPS. The step from High to Ultra costs 47 FPS, which is proportionally larger than the 1080p High-to-Ultra gap. This suggests that the Ultra preset's additional load scales more aggressively with resolution, likely due to increased shadow and post-processing resolution.

At 3840x2160, the averages are: Low at 124.2 FPS, Medium at 100.4 FPS, High at 84.1 FPS, and Ultra at 50.5 FPS. The High-to-Ultra penalty here is 33.6 FPS, which is smaller in absolute terms than at lower resolutions but represents a 40% reduction in frame rate. The 4K Ultra result is the only measured configuration that drops below 60 FPS, confirming that this preset pushes the GPU to its limit.

How This Combo Ranks

The combination of the AMD Ryzen 7 5700 and AMD Radeon RX 7800 XT ranks 627th out of 1741 tested combos in Downfall. This places it in the upper portion of the database — roughly the 64th percentile of all combinations. The ranking reflects the GPU's strong 76th percentile position and the CPU's 84th percentile standing, though the game's performance is more dependent on the GPU than the CPU.

The 627th rank out of 1741 combos means there are 626 combinations that achieve higher average frame rates in this game, but the majority of tested hardware (1114 combos) falls below this pairing. Given that the RX 7800 XT's nearest rivals are all within 0.7% of its average benchmark score, the ranking is likely influenced more by the specific game's optimization than by raw hardware capability. The CPU's nearest rival, the Intel Core i9-9900K, is only 0.7% ahead in average score, which indicates that the Ryzen 7 5700 is not a limiting factor in this pairing.

CPU Role

The AMD Ryzen 7 5700 provides 8 cores and 16 threads based on the Zen 3 architecture, with a base clock of 3.70 GHz and a boost clock of 4.60 GHz. The 16 MB of L3 cache and 51.2 GB/s memory bandwidth are adequate for feeding the RX 7800 XT in Downfall. The CPU's 84th percentile ranking among all processors reflects its strong single-thread performance, evidenced by the 3DMark single-thread score of 901 and the Cinebench R23 single-core score of 2916.

In this game, the CPU's role is secondary to the GPU, as the measured FPS scaling shows. At 1080p Low, the 282 FPS result indicates that the CPU can drive very high frame rates when the GPU is not heavily loaded. However, the fact that the 1080p Ultra result (120.7 FPS) is lower than the 4K Low result (124.2 FPS) suggests that the CPU is not the bottleneck in either case — the GPU's settings-dependent workload is what determines the final frame rate.

The Ryzen 7 5700's 8-core, 16-thread configuration is more than sufficient for a horror game from 2016, which likely does not scale well beyond a few threads. The CPU's multi-threaded scores — Cinebench R23 multi-core at 20655 and Passmark multi-thread at 24303 — are far beyond what this game would require. The nearest CPU rival, the Intel Core i9-9900K, scores within 0.7% in average benchmarks, confirming that this processor is well-matched to the GPU without leaving performance on the table.
