Downfall

The AMD Ryzen 7 5800X and AMD Radeon RX 6600 combination delivers a highly playable experience in Downfall, but the data reveals a system that is consistently GPU-bound at higher resolutions while showing surprising headroom at 1080p. The pairing ranks in the 21st percentile of tested combos, placing it at position 1374 out of 1741, which is competitive for a mid-range setup in this horror title.

Resolution Scaling

The frame rate drop from 1080p to 4K is substantial across all settings, confirming that the Radeon RX 6600 is the primary limiting factor at higher resolutions. At Low settings, the average FPS falls from 177.5 at 1920x1080 to 126.8 at 2560x1440, then sharply to 79.1 at 3840x2160. This represents a 55.4% reduction from 1080p to 4K, indicating that pixel throughput becomes the bottleneck as resolution increases.

At Medium settings, the scaling follows a similar pattern: 140.4 FPS at 1080p, 101.8 at 1440p, and 64.6 at 4K. The drop from 1440p to 4K is particularly steep at 36.6%, which suggests the 8 GB of GDDR6 memory and 128-bit bus are being saturated at the higher pixel count. High settings show 115.3 FPS at 1080p, 84 at 1440p, and 54.3 at 4K, with the 4K figure still remaining above the 50 FPS threshold.

Ultra settings produce the most dramatic scaling, with 76 FPS at 1080p dropping to 53.7 at 1440p and finally 31.1 at 4K. The 4K Ultra result is the only configuration that falls below 30 FPS, making it the only unplayable combination in the dataset. The consistent pattern across all presets points to the GPU's 1792 shading units and 64 ROPs as the limiting factor, while the CPU's 8 cores and 16 threads never appear to constrain performance in this title.

Settings Recommendations

For the best balance of visual quality and performance, the High preset at 2560x1440 is the optimal choice. This configuration delivers 84 FPS, which is comfortably above the 60 FPS target while still providing the visual fidelity expected from a modern horror title. The 1080p High setting at 115.3 FPS offers an even smoother experience for those prioritizing frame rate, but the 1440p option provides a meaningful resolution upgrade for only a 27.1% drop in performance.

Ultra settings should be avoided at 4K entirely, as the 31.1 FPS result is below the threshold for smooth gameplay. At 1440p, Ultra manages 53.7 FPS, which is playable but noticeably less fluid than High. The Medium preset at 1440p, producing 101.8 FPS, serves as an excellent alternative for users who want a high frame rate without dropping to Low. At 1080p, Ultra at 76 FPS is acceptable, but High offers a 51.7% improvement in frame rate with minimal visual difference in most scenes.

The data suggests that the RX 6600's 8 GB of VRAM is sufficient for High settings at all resolutions, but Ultra at 4K pushes the memory bandwidth to its limits. Users with 4K displays should stick to Low or Medium settings, where 79.1 and 64.6 FPS respectively provide the best playable experience. For competitive play or high refresh rate monitors, 1080p Low at 177.5 FPS is the clear winner.

How This Combo Ranks

The combination of the Ryzen 7 5800X and Radeon RX 6600 ranks 1374 out of 1741 tested configurations in Downfall, placing it in the bottom 21% of the database. This positioning is primarily attributable to the GPU, which sits at the 69th percentile among all GPUs, while the CPU ranks at the 84th percentile. The 16-thread processor provides 9899 points in Cinebench R20 multicore, but the RX 6600's 15096 passmark G3D score limits overall gaming performance.

Compared to its nearest GPU rivals, the RX 6600 trades blows with the AMD Radeon 890M (0% delta), Radeon RX 580 2048SP (-0.2%), and Radeon RX 6700M (0.2%), while trailing the NVIDIA GeForce RTX 3060 Ti by 0.5%. These small deltas indicate that the RX 6600 is positioned in a tightly contested mid-range segment. The CPU's nearest rivals, including the Ryzen 7 5800 (0.3% ahead) and Ryzen 5 8500GE (0.4% behind), show similarly close margins.

The 1741 total combos in the database include many high-end configurations, so the 1374th rank reflects the GPU's mid-range positioning rather than any fundamental flaw in the pairing. The system's ability to maintain 84 FPS at 1440p High places it well within the playable range for most users, even if it doesn't compete with top-tier setups. The 8-core, 16-thread CPU ensures that this combo will not be CPU-limited in Downfall, allowing the GPU's performance ceiling to be fully realized.

GPU Role

The AMD Radeon RX 6600's performance in Downfall is defined by its 8 GB of GDDR6 memory on a 128-bit bus, providing 224.0 GB/s of bandwidth. The card's boost clock of 2491 MHz and game clock of 2044 MHz enable a pixel rate of 159.4 GPixel/s and a texture rate of 279.0 GTexel/s, figures that prove adequate for 1080p and 1440p but struggle at 4K. The 1792 shading units and 64 ROPs deliver 8.928 TFLOPS of FP32 compute, which translates to the measured frame rates.

The GPU's 69th percentile ranking among all GPUs places it in the upper-mid range, and its 25235 average benchmark score aligns closely with rivals like the Radeon 890M (25246) and Radeon RX 580 2048SP (25287). The RTX 3060 Ti's 0.5% advantage in average score does not translate to a meaningful difference in Downfall's measured results. The card's 132 W TDP and 300 W suggested PSU indicate an efficient design that does not require excessive power delivery.

At 4K, the GPU's memory bandwidth becomes the limiting factor. The drop from 64.6 FPS at Medium to 54.3 FPS at High, and then to 31.1 FPS at Ultra, shows that the 224 GB/s bandwidth cannot sustain the texture and geometry loads of the highest preset. The 14 Gbps effective memory speed, while adequate for 1440p, is insufficient for 4K Ultra in this title. The card's PCIe 4.0 x8 interface provides sufficient bandwidth for the CPU-GPU communication, as evidenced by the lack of CPU bottlenecking.

Measured FPS Breakdown

At 1920x1080, the RX 6600 delivers 177.5 FPS on Low, 140.4 on Medium, 115.3 on High, and 76 on Ultra settings. The 101.5 FPS spread between Low and Ultra demonstrates the GPU's capability at this resolution, with even the most demanding preset maintaining a playable frame rate. At 2560x1440, performance drops to 126.8 FPS on Low, 101.8 on Medium, 84 on High, and 53.7 on Ultra. The 1440p results show a 28.6% average reduction compared to 1080p across settings, consistent with the increased pixel count.

At 3840x2160, the card produces 79.1 FPS on Low, 64.6 on Medium, 54.3 on High, and 31.1 on Ultra. The 4K Ultra result is the only configuration below 30 FPS, making it unsuitable for smooth gameplay. The scaling from 1440p to 4K is more severe than from 1080p to 1440p, with an average drop of 43.7% across all settings. This nonlinear scaling indicates that the GPU hits a memory bandwidth wall at 4K, particularly at higher presets.

Across all resolutions, the step from Low to Medium costs roughly 20-22% in frame rate, while the step from Medium to High costs an additional 18-20%. The step from High to Ultra is the most expensive, costing 34% at 1080p, 36% at 1440p, and 43% at 4K. This pattern suggests that Ultra settings introduce disproportionately heavy effects that strain the GPU's resources.

CPU Role

The AMD Ryzen 7 5800X provides 8 cores and 16 threads based on the Zen 3 architecture, with a base clock of 3.80 GHz and boost clock of 4.70 GHz. The processor's 32 MB of L3 cache and 51.2 GB/s memory bandwidth ensure that game data flows efficiently to the GPU. In Downfall, which is not a CPU-intensive title, the 5800X's capabilities far exceed the game's requirements, preventing any processor-induced frame rate dips.

The CPU's 3DMark scores, including 943 for single-thread and 7578 for max threads, indicate strong per-core performance that benefits games with limited thread usage. The 5800X's 84th percentile ranking among all CPUs, with an average benchmark score of 27606, places it above the Ryzen 7 5800 (27535, 0.3% delta) and below the Ryzen 5 8500GE (27708, -0.4%). These margins are negligible, confirming that the 5800X is well-positioned in its segment.

The measured FPS data shows no evidence of CPU bottlenecking, as frame rates scale consistently with GPU load across resolutions. At 1080p Low, the 177.5 FPS result is likely approaching the CPU's practical limit, but the GPU is still the primary constraint. The 16 threads handle background tasks and draw calls without issue, and the 7 nm process node keeps power consumption manageable at 105 W TDP. The CPU's 4,150 million transistors on a 74 mm² die provide ample compute resources for this horror title.
