Downfall

The AMD Ryzen 7 5800X3D paired with the AMD Radeon RX 7800 XT in Downfall produces a dataset that is as much about the game’s engine limits as it is about the hardware itself. The measured frames per second (FPS) reveal a system that is overwhelmingly GPU-bound at higher resolutions, but the margins between settings presets hint at a title that scales aggressively with visual fidelity. This analysis breaks down exactly where the bottleneck sits and what the numbers mean for a 1741-combo field.

Resolution Scaling

The FPS drop from 1920x1080 to 3840x2160 is steep and consistent, but the shape of that curve changes depending on the quality preset. At Low settings, the system delivers 282.8 FPS at 1080p, which falls to 198 FPS at 1440p (a 30.0% reduction) and then to 124.5 FPS at 4K (a 37.1% further drop). That is a total decline of 56.0% from 1080p to 4K, which is substantial but not catastrophic — it suggests the CPU is still feeding the GPU enough data at lower resolutions to keep frame rates high.

The Ultra preset tells a different story. At 1080p, the combo hits 119.4 FPS, but at 1440p that falls to 81.4 FPS (a 31.8% drop), and at 4K it collapses to 49.9 FPS (a 38.7% further decline). The total drop from 1080p Ultra to 4K Ultra is 58.2%, which is nearly identical to the Low preset’s percentage loss. This indicates that the scaling penalty is resolution-driven rather than settings-driven — the GPU is the limiting factor in both cases, but the absolute numbers are far lower on Ultra because the rendering load is heavier.

The Medium and High presets sit between these extremes. High goes from 185.4 FPS at 1080p to 131.9 FPS at 1440p (a 28.9% drop) and then to 84.7 FPS at 4K (a 35.8% further drop). Medium follows a similar path: 226.4 FPS at 1080p, 162.9 FPS at 1440p (a 28.1% drop), and 104.9 FPS at 4K (a 35.6% further drop). The consistency of these percentage drops — hovering around 28-30% for the 1080p-to-1440p step and 35-39% for the 1440p-to-4K step — strongly implies that the RX 7800 XT’s rendering pipeline is the primary constraint, not the CPU or memory bandwidth.

CPU Role

The Ryzen 7 5800X3D brings 8 cores and 16 threads, running at a base clock of 3.40 GHz and a boost clock of 4.50 GHz. Its architecture is Zen 3 on the Vermeer codename, fabricated on TSMC’s 7 nm process. The standout feature is the 96 MB of shared L3 cache, which is massive for a desktop chip and typically helps in games that are sensitive to memory latency. In Downfall, a horror title from 2016, the CPU’s role appears to be secondary — the data shows that even at 1080p Low, the combo reaches 282.8 FPS, which is far beyond what most displays can show, suggesting the CPU is not a bottleneck at lower resolutions.

Benchmarks for this chip show a 3DMark single-thread score of 884 and a multi-thread score of 7299, with a Cinebench R23 multi-core score of 24063. The single-thread performance is modest compared to modern chips, but the 3D V-Cache (implied by the 96 MB L3) likely compensates in gaming workloads. The percentileVsAllCpus is 83, meaning it outperforms 83% of all tested CPUs. Its nearest rivals include the AMD EPYC 8024P (deltaPct 0.1), Intel Core i9-11900K (deltaPct 0.1), and AMD Ryzen 5 7600 (deltaPct -0.2) — all within a fraction of a percent in average benchmark score, indicating that the 5800X3D is competitive but not dominant in synthetic tests.

In Downfall, the CPU’s impact is most visible when comparing the 1080p Low and Medium results. The jump from 282.8 FPS to 226.4 FPS is a 19.9% reduction, which is larger than the resolution-based drops seen at higher settings. This suggests that at very high frame rates, the CPU’s ability to feed draw calls becomes a secondary factor, but it is not the primary limiter — the GPU still has headroom. The 8-core, 16-thread configuration is more than adequate for a 2016 title, and the 51.2 GB/s memory bandwidth on DDR4 is sufficient for this workload.

GPU Role

The RX 7800 XT is the star of this dataset, and its specifications explain why. It features 16 GB of GDDR6 memory on a 256-bit bus, delivering 624.1 GB/s of bandwidth. The GPU has 3840 shading units, 240 TMUs, and 96 ROPs, with a boost clock of 2430 MHz and a game clock of 2124 MHz. Its FP32 performance is 37.32 TFLOPS, and it supports DirectX 12 Ultimate, Vulkan 1.4, and OpenGL 4.6. The 5 nm process node and 28,100 million transistors indicate a modern, power-efficient design.

The percentileVsAllGpus is 76, meaning it outperforms 76% of all tested GPUs. Its nearest rivals include the AMD FirePro S9300 X2 (deltaPct 0.2), NVIDIA P104-100 (deltaPct -0.4), and NVIDIA T600 Mobile (deltaPct -0.7). These are all within a 0.7% range in average benchmark score, which is surprisingly tight for such different products — it suggests the RX 7800 XT is a mid-to-high tier performer rather than a top-tier one.

In Downfall, the GPU’s role is clearly dominant. The 4K Ultra result of 49.9 FPS is the lowest in the dataset, and it is nearly half the 1080p High result of 185.4 FPS. This is a 73.1% reduction, which is massive. The VRAM capacity of 16 GB is unlikely to be a limiting factor in a 2016 game, but the sheer rendering load at 4K Ultra pushes the GPU to its limits. The data shows that the GPU is the bottleneck at all resolutions above 1080p Medium, and even at 1080p Low, the frame rate is so high that other components — likely the CPU or memory latency — start to become relevant.

How This Combo Ranks

In the global ranking for Downfall, this combo sits at rank 651 out of 1741 tested combinations. That places it in the 62.6th percentile of all combos, which is above average but not exceptional. Given that the GPU is at the 76th percentile and the CPU is at the 83rd percentile, the combo rank being lower than both suggests that Downfall is not particularly well-optimized for this hardware pairing, or that other combos with similar components achieve higher FPS.

The rank of 651 out of 1741 means there are 1090 combos that perform worse and 650 that perform better. This is a competitive position, but it is not a top-tier result. The data implies that while each component is individually strong, their combination in this game does not produce a sum greater than its parts. The CPU’s high percentile does not translate into a proportional FPS advantage, likely because the GPU becomes the limiting factor at most settings.

Measured FPS Breakdown

At 1920x1080, the combo delivers its highest frame rates across all presets. Low settings produce 282.8 FPS, Medium yields 226.4 FPS, High reaches 185.4 FPS, and Ultra drops to 119.4 FPS. The gap between Low and Ultra is 163.4 FPS, which is a 57.8% reduction. This is the widest spread in the dataset, indicating that at 1080p, the settings preset has a massive impact on performance.

At 2560x1440, the numbers scale down proportionally. Low achieves 198 FPS, Medium hits 162.9 FPS, High reaches 131.9 FPS, and Ultra falls to 81.4 FPS. The difference between Low and Ultra is 116.6 FPS, a 58.9% reduction. This is remarkably consistent with the 1080p spread, confirming that the settings scaling is resolution-independent.

At 3840x2160, the frame rates become playable but not excessive. Low produces 124.5 FPS, Medium hits 104.9 FPS, High reaches 84.7 FPS, and Ultra drops to 49.9 FPS. The Low-to-Ultra gap is 74.6 FPS, a 59.9% reduction. This is the largest percentage drop in the dataset, suggesting that at 4K, the Ultra preset is particularly punishing on the GPU.

Settings Recommendations

The measured data supports a clear recommendation: High settings at 1440p offer the best balance of visual quality and performance. At 2560x1440 High, the combo delivers 131.9 FPS, which is well above the 60 FPS threshold for smooth gameplay and leaves headroom for future driver optimizations. The 4K High result of 84.7 FPS is also playable, but the 1440p High option provides a more comfortable margin.

For players seeking maximum frame rates, 1080p Low at 282.8 FPS is the extreme choice, but it sacrifices visual fidelity in a horror game where atmosphere matters. The Medium preset at 1080p (226.4 FPS) or 1440p (162.9 FPS) offers a better middle ground. The Ultra preset is not recommended at any resolution, as the 4K Ultra result of 49.9 FPS is below the 60 FPS standard, and the 1080p Ultra result of 119.4 FPS does not justify the visual gains over High.
