Downfall

The AMD Ryzen 7 5800X and NVIDIA GeForce RTX 3080 combination delivers a powerful, high-refresh-rate experience in Downfall, a 2016 horror title. The data shows this pairing is highly capable across resolutions, though the demands of Ultra settings reveal the GPU's limits, while the CPU ensures consistent frame delivery at lower settings. This analysis breaks down the measured performance, component roles, and how this specific combo stacks up against other tested configurations.

CPU Role — cores, clocks, and how they relate to this game's results

The AMD Ryzen 7 5800X is an 8-core, 16-thread processor based on the Zen 3 architecture (codenamed Vermeer), built on a 7 nm process at TSMC. It operates with a base clock of 3.80 GHz and a boost clock of 4.70 GHz, with a 105 W TDP. The chip features a 32 MB L3 cache, with 64 KB of L1 and 512 KB of L2 per core. Memory support is dual-channel DDR4 with a bandwidth of 51.2 GB/s, and it connects via PCIe Gen 4 with 20 lanes.

In Downfall, the CPU's role is primarily to feed the GPU with draw calls and manage game logic. At 1080p with Low settings, the combo achieves 297.8 FPS, which is well above the thresholds where a weaker processor might bottleneck. The Ryzen 7 5800X’s strong single-thread performance — evidenced by a 3DMark single-thread score of 943 and a Cinebench R23 single-core score of 3327 — ensures that frame pacing remains stable even when the GPU is not the limiting factor. The multi-threaded capabilities, with a Cinebench R23 multi-core score of 23571, also handle background tasks without interfering with frame delivery.

The processor's benchmark scores place it at the 84th percentile among all CPUs, with an average benchmark score of 27606. Its nearest rival, the AMD Ryzen 7 5800, scores 27535, a delta of 0.3%, indicating nearly identical performance. The Intel Core i5-12600KF is 0.8% ahead, while the AMD Ryzen 5 8500GE and Intel Core i7-13700H are 0.4% behind. This tight grouping suggests that in Downfall, the 5800X provides ample headroom for the RTX 3080, as the game's horror setting likely does not impose extreme multi-threaded workloads, allowing the CPU to deliver consistently high frame rates without becoming a constraint.

How This Combo Ranks — use comboRankInGame vs other tested combos

This specific combination of the AMD Ryzen 7 5800X and NVIDIA GeForce RTX 3080 ranks 511th out of 1741 tested combos in Downfall. This places it in the top 29% of all configurations, which is a strong showing given the breadth of hardware tested. The rank reflects a balance between CPU and GPU capabilities, where the 5800X's solid performance and the RTX 3080's high-end graphics power combine to deliver excellent results.

The ranking suggests that while this combo is not in the absolute top tier — likely occupied by newer flagship CPUs and GPUs — it still outperforms the vast majority of systems. The delta between this combo and those ranked higher is not specified, but the percentile position indicates that users with this setup can expect a smooth experience at high refresh rates. The fact that it ranks 511th out of 1741 means there are 1230 combos that are slower, reinforcing that this pairing is well above average for Downfall. The GPU's benchmark percentile at 80% and the CPU's at 84% both contribute to this mid-to-upper tier ranking, with neither component dragging the overall score down significantly.

Resolution Scaling — how FPS drops from 1080p to 4K and what it says about the limiting component

The measured FPS data reveals a clear scaling pattern as resolution increases, highlighting the shift in bottleneck from the CPU to the GPU. At 1080p with Low settings, the combo achieves 297.8 FPS. Moving to 1440p Low, the frame rate drops to 215.5 FPS, a reduction of 27.6%. At 4K Low, the FPS falls further to 131.7, a 38.9% drop from 1440p. This scaling indicates that at lower resolutions, the CPU is capable of pushing very high frame rates, but the GPU's workload increases significantly as pixel count rises.

The pattern is more pronounced at higher settings. At 1080p Ultra, the combo hits 127.8 FPS. At 1440p Ultra, it drops to 93.2 FPS (a 27.1% decrease), and at 4K Ultra, it falls to 55.7 FPS (a 40.2% decrease from 1440p). This consistent proportional drop across settings suggests that the RTX 3080 is the primary limiting factor at higher resolutions and settings, as the CPU has ample headroom to maintain frame delivery. At 1080p Low, the 297.8 FPS result is likely near the CPU's practical limit for the game engine, but as resolution increases, the GPU's rendering load becomes the dominant constraint. The data shows that the RTX 3080, with its 10 GB of GDDR6X memory and 760.3 GB/s bandwidth, can handle 4K Ultra at 55.7 FPS, but users seeking higher frame rates at 4K would need to lower settings to Medium (107.6 FPS) or High (91.8 FPS).

Measured FPS Breakdown — resolution by resolution, settings by settings, exact numbers

The measured FPS provides a complete picture of performance across three resolutions and four quality presets. At 1920x1080, the combo delivers 297.8 FPS on Low, 244.6 FPS on Medium, 202.7 FPS on High, and 127.8 FPS on Ultra. The gap between Low and Medium is 53.2 FPS, while the drop from High to Ultra is 74.9 FPS, indicating that Ultra settings impose a significant rendering cost due to advanced effects and higher texture detail.

At 2560x1440, the results are 215.5 FPS on Low, 173.0 FPS on Medium, 143.4 FPS on High, and 93.2 FPS on Ultra. The transition from 1080p to 1440p reduces frame rates by roughly 27-28% across settings, which is consistent with the increase in pixel count from 2.07 million to 3.69 million. The Ultra preset at 1440p still maintains 93.2 FPS, which is playable for a horror title, but the drop from High to Ultra is 50.2 FPS, showing a steep penalty for maximum quality.

At 3840x2160, the performance is 131.7 FPS on Low, 107.6 FPS on Medium, 91.8 FPS on High, and 55.7 FPS on Ultra. The 4K resolution demands significant GPU resources, and the Ultra preset's 55.7 FPS is the only result below 60 FPS across all tested configurations. The scaling from 1440p to 4K shows a 38.9% drop on Low, 37.8% on Medium, 36.0% on High, and 40.2% on Ultra, indicating that the RTX 3080's memory bandwidth and compute power are stretched at this resolution, particularly with Ultra settings enabled.

GPU Role — VRAM, clocks, and how they relate to this game's results

The NVIDIA GeForce RTX 3080 is built on the Ampere architecture with the GA102 chip, manufactured on Samsung's 8 nm process. It features 8704 shading units, 272 texture mapping units, and 96 raster operations pipelines, along with 68 RT cores and 272 tensor cores. The GPU has a base clock of 1440 MHz and a boost clock of 1710 MHz, with memory running at 19 Gbps effective. It is equipped with 10 GB of GDDR6X memory on a 320-bit bus, providing a bandwidth of 760.3 GB/s.

In Downfall, the RTX 3080's role is pivotal, especially at higher resolutions and settings. The 10 GB VRAM is sufficient for 4K Ultra, as the game's horror environments do not appear to exceed this capacity, avoiding potential stuttering from memory swapping. The GPU's FP32 performance of 29.77 TFLOPS and texture rate of 465.1 GTexel/s directly impact the frame rates seen at 4K, where the Ultra preset yields 55.7 FPS. This result is below the 60 FPS threshold, but the High preset at 91.8 FPS shows that the GPU can deliver smooth performance with a modest quality reduction.

The RTX 3080's benchmark scores place it at the 80th percentile among all GPUs, with an average score of 35787. Its nearest rivals include the AMD Radeon Pro Duo (0.2% behind) and the AMD Radeon RX 7900 GRE (0.9% behind), while the NVIDIA GeForce RTX 5070 Ti Mobile is 1% ahead. The GPU's 3DMark Steel Nomad DX12 score of 4407 and Passmark G3D score of 25086 confirm its high-end status. The data indicates that the RTX 3080 is well-matched to the Ryzen 7 5800X, providing a balanced system where the GPU becomes the primary bottleneck only at 4K Ultra, and even then, it maintains playable frame rates. For users prioritizing high refresh rates, the 1440p High preset at 143.4 FPS is the sweet spot, showcasing the GPU's ability to deliver both resolution and speed.
