Downfall

The AMD Ryzen 5 5500X3D and AMD Radeon RX 7800 XT pairing delivers a robust 1080p and 1440p experience in Downfall, but the data reveals a sharp performance cliff at 4K Ultra settings. This combination of a 6-core Zen 3 processor and a 16 GB RDNA 3 graphics card demonstrates a clear division of labor, where the GPU becomes the primary bottleneck as resolution and graphical fidelity increase.

Resolution Scaling

The measured FPS data shows a predictable inverse relationship between resolution and frame rate, but the magnitude of the drop is telling. At 1080p High settings, the combo averages 189 FPS. Moving to 2560x1440 High drops that to 135 FPS, a 28.6% reduction. The jump to 3840x2160 High further reduces performance to 84 FPS, which is a 37.8% drop from the 1440p figure. This scaling pattern is typical for a GPU-bound scenario, where the RX 7800 XT’s rendering workload increases exponentially with pixel count.

The trend becomes more dramatic when examining the Low settings preset. At 1920x1080 Low, the system achieves 282 FPS, which is an exceptionally high ceiling that suggests the CPU is not holding the GPU back at this resolution. At 2560x1440 Low, the average FPS is 202, and at 3840x2160 Low, it drops to 125 FPS. The fact that a 4K Low preset still produces over 120 FPS indicates that the GPU has substantial headroom when pixel shading requirements are minimized.

The most significant scaling anomaly appears in the Ultra preset. At 1080p Ultra, the average is 118 FPS. At 1440p Ultra, it falls to 85 FPS, and at 4K Ultra, it plummets to just 53 FPS. The gap between 1080p Ultra and 4K Ultra represents a 55.1% performance loss. This steep decline at 4K Ultra suggests that the combination of high resolution and maximum settings (likely including heavy post-processing and shadow effects) overwhelms the RX 7800 XT’s 96 ROPs and 16 GB frame buffer. The data indicates that 4K Ultra is not a viable target for this pairing, while 1440p Ultra remains playable.

CPU Role

The AMD Ryzen 5 5500X3D is built on the Zen 3 architecture with a 7 nm process and features 6 cores and 12 threads. Its base clock is 3.00 GHz with a boost clock of 4.00 GHz, and it carries 96 MB of shared L3 cache. In the Passmark multithread benchmark, it scores 20363, and its single-thread score is 2941. These figures place the CPU in the 85th percentile against all tested CPUs, indicating strong overall performance for a mid-range desktop part.

In Downfall, a horror title that often features dynamic lighting and physics simulations, the CPU’s role appears secondary at higher resolutions. The benchmark results show that at 1080p Low, where the GPU load is lightest, the system reaches 282 FPS. This suggests that the CPU can feed frames quickly enough to avoid becoming the limiting factor even at high frame rates. However, the processor’s 105 W TDP and 3.00 GHz base clock are modest, and the data implies that the CPU’s ceiling is sufficient for this game at all tested settings.

The 5500X3D’s nearest rivals in the Passmark database include the AMD Ryzen 5 5600F (0.2% faster) and the Intel Core Ultra 5 225 (0.2% faster), as well as the AMD Ryzen AI 7 PRO 450 (0.2% slower) and Intel Core i9-12900T (0.3% slower). These microscopic deltas indicate that the 5500X3D sits squarely in a competitive performance band, meaning any FPS differences in Downfall are far more attributable to the GPU than to this CPU. The data suggests that the 5500X3D provides consistent frame pacing without bottlenecking the RX 7800 XT, even at lower resolutions where CPU overhead is more relevant.

How This Combo Ranks

In the database of tested configurations for Downfall, this pairing of the AMD Ryzen 5 5500X3D and AMD Radeon RX 7800 XT achieves a rank of 1234 out of 3716 total combos. This places the system in the 66.8th percentile of all tested setups, meaning it outperforms roughly two-thirds of all configurations. The ranking is a composite of the CPU and GPU’s measured FPS across all resolution and settings combinations.

The rank indicates that while this is not a top-tier enthusiast setup, it is far from a budget compromise. The GPU’s performance percentile is 51, which is middling, but the CPU’s 85th percentile helps boost the overall combo. The data suggests that the primary drag on the ranking is the GPU’s inability to sustain high frame rates at 4K Ultra, where the 53 FPS average is a significant outlier compared to the otherwise strong 1080p and 1440p results. If the user targets 1440p High or Medium, this combo would likely rank considerably higher, as those settings show FPS figures that are competitive with more expensive hardware.

GPU Role

The AMD Radeon RX 7800 XT is built on the RDNA 3.0 architecture with a 5 nm process and features 16 GB of GDDR6 memory on a 256-bit bus, yielding a bandwidth of 624.1 GB/s. Its boost clock is 2430 MHz, and it has 3840 shading units, 240 TMUs, and 96 ROPs. The GPU’s Passmark G3D score is 24176, and its 3DMark Steel Nomad DX12 score is 4157. Its average benchmark score is 11627, placing it in the 51st percentile of all GPUs.

The GPU’s role in Downfall is clearly the dominant factor in determining FPS at higher resolutions. The data shows that at 1080p Low, the system hits 282 FPS, but at 4K Ultra, it falls to 53 FPS. This 81.2% reduction in performance is directly attributable to the GPU’s rendering limits. The 16 GB VRAM is likely sufficient for the game’s textures, but the 96 ROPs become saturated at 4K with Ultra settings, which often include high-resolution shadows and ambient occlusion.

Interestingly, the RX 7800 XT’s nearest rivals in the Passmark database include the NVIDIA GeForce GTX 1660 (0.5% faster) and the AMD Radeon RX 6500 XT (1.8% faster), while the AMD Radeon Pro 5500M and NVIDIA Tesla K20c are 0.9% and 1.3% slower, respectively. These rivals are largely older or lower-tier cards, which suggests that the RX 7800 XT’s raw compute score is not exceptional. However, in Downfall, the GPU’s real-world performance at 1440p High (135 FPS) and 4K Medium (103 FPS) demonstrates that its memory bandwidth and 16 GB frame buffer provide a practical advantage over those rivals in a modern title.

Measured FPS Breakdown

The measured FPS data for this combo in Downfall covers four resolutions and four settings presets, with the Medium preset being the only one that includes minimum and maximum frame rates.

At 1920x1080, the performance is uniformly high. Low settings produce an average of 282 FPS, Medium yields 231 FPS (with a range of 196-266 FPS), High reaches 189 FPS, and Ultra drops to 118 FPS. The spread from Low to Ultra is 164 FPS, indicating that the GPU scales well with settings at this resolution, and the CPU keeps up even at the highest frame rates.

At 2560x1440, the averages are 202 FPS for Low, 165 FPS for Medium (range 140-190 FPS), 135 FPS for High, and 85 FPS for Ultra. The transition from 1080p to 1440p costs roughly 28-30% performance across all settings, which is a typical pixel-count penalty. The 1440p Ultra figure of 85 FPS remains smooth, proving that this resolution is the combo’s comfort zone.

At 3840x2160, the data shows a steeper decline. Low settings average 125 FPS, Medium averages 103 FPS (range 87-118 FPS), High averages 84 FPS, and Ultra averages 53 FPS. The gap between Low and Ultra at 4K is 72 FPS, which is proportionally larger than at other resolutions. The 4K Ultra result is the only sub-60 FPS figure in the entire dataset, and the 4K High result of 84 FPS is borderline. The data indicates that 4K gaming is only recommended with Medium settings or lower to maintain a consistent 100+ FPS experience.
