Downfall

The AMD Ryzen 7 7800X3D (launch MSRP $449) paired with the AMD Radeon RX 6700 XT (launch MSRP 479 USD) is a combination that targets high-refresh 1080p and capable 1440p gaming. In Downfall, a 2016 horror title, the measured frame rates reveal a system that is CPU-strong but GPU-limited at higher resolutions. This analysis examines the CPU and GPU roles, resolution scaling, combo ranking, and measured FPS to provide settings guidance.

CPU Role

The Ryzen 7 7800X3D is an 8-core, 16-thread processor based on the Zen 4 architecture, fabricated on a 5 nm process. It operates at a base clock of 4.20 GHz and a boost clock of 5.00 GHz, with a TDP of 120 W. Its defining feature is a large 96 MB shared L3 cache, which is particularly beneficial for gaming workloads that repeatedly access the same data. The CPU’s average benchmark score is 31580, placing it in the 87th percentile of all CPUs. Its nearest rivals include the Intel Core i7-12700F, which scores 0.1% lower, and the AMD Ryzen 9 5980HX, which is 0.3% lower. In single-threaded tasks, the 7800X3D achieves a Cinebench R23 score of 4115, while its multi-threaded score reaches 29149. These numbers indicate strong per-core performance and ample thread capacity.

In Downfall, the CPU’s high single-thread performance and large cache likely allow the game to maintain high frame rates when the GPU is not the bottleneck. At 1080p with Low settings, the combo reaches 229.8 FPS, a figure that suggests the CPU can feed the GPU with enough data to saturate its output. The 8-core/16-thread configuration provides headroom for the game’s background tasks and any additional system processes. The 3DMark single-thread score of 959 and the Passmark single-thread score of 3759 further confirm that the CPU excels in latency-sensitive scenarios. However, as resolution increases, the CPU’s role diminishes relative to the GPU, and the frame rate becomes more dependent on the graphics card’s throughput.

GPU Role

The Radeon RX 6700 XT is built on the RDNA 2.0 architecture and features 12 GB of GDDR6 memory on a 192-bit bus, delivering 384.0 GB/s of bandwidth. Its base clock is 2321 MHz, with a boost clock of 2581 MHz and a game clock of 2424 MHz. The GPU contains 2560 shading units, 160 texture mapping units, and 64 ROPs, along with 40 ray-tracing cores. Its FP32 performance is 13.21 TFLOPS, and it supports DirectX 12 Ultimate, Vulkan 1.4, and OpenGL 4.6. The GPU’s average benchmark score is 33721, placing it in the 77th percentile of all GPUs. Its nearest rivals include the AMD Radeon RX 6800, which scores 0.7% lower, and the AMD Radeon HD 7950, which scores 1% higher. The Passmark G3D score of 19786 and the 3DMark Steel Nomad score of 2435 provide additional context for its gaming performance.

In Downfall, the GPU’s memory bandwidth and clock speeds determine the frame rate at higher resolutions and settings. At 4K Ultra, the combo drops to 40.6 FPS, indicating that the GPU is the limiting factor. The 12 GB VRAM is sufficient for the game’s textures, but the raw compute power is not enough to sustain high frame rates at 4K with maximum settings. At 1080p, the GPU can deliver 229.8 FPS on Low, but this is still below the CPU’s potential ceiling, suggesting that the GPU is the primary constraint even at lower resolutions. The GPU’s 77th percentile ranking places it in the upper-middle tier, which aligns with the observed performance: capable at 1080p and 1440p, but struggling at 4K Ultra.

Resolution Scaling

The measured FPS data shows a clear pattern of decreasing performance as resolution increases. At High settings, the average frame rate drops from 152.2 FPS at 1080p to 111.9 FPS at 1440p, a 26.5% reduction, and then to 70.5 FPS at 4K, a further 37% reduction. At Low settings, the drop is from 229.8 FPS at 1080p to 165.9 FPS at 1440p (27.8% lower) and then to 99.6 FPS at 4K (40% lower). Medium settings follow a similar trend: 189.6 FPS at 1080p, 133.2 FPS at 1440p (29.7% lower), and 82.2 FPS at 4K (38.3% lower). Ultra settings show the steepest decline: 94.3 FPS at 1080p, 71.1 FPS at 1440p (24.6% lower), and 40.6 FPS at 4K (42.9% lower).

The scaling indicates that the GPU becomes increasingly the bottleneck as resolution rises. The percentage drop from 1440p to 4K is consistently larger than the drop from 1080p to 1440p, which is typical of a GPU-limited scenario. At 1080p, the CPU’s strength allows the GPU to operate near its maximum output, but the GPU’s performance ceiling is still the limiting factor. At 4K, the GPU’s compute and memory bandwidth are insufficient to maintain high frame rates, especially on Ultra settings. The data suggests that the combo is well-balanced at 1440p, where High and Medium settings deliver 111.9 and 133.2 FPS respectively, but at 4K, only Low and Medium exceed 60 FPS.

How This Combo Ranks

The combo ranks 946 out of 1741 tested combinations in Downfall, placing it in the 54th percentile. This means that 945 other combos achieve higher average frame rates, while 795 achieve lower. The ranking is below the median, which is notable given that the CPU is in the 87th percentile and the GPU is in the 77th percentile. The discrepancy suggests that the pairing is not optimally balanced for this game. The CPU’s high performance is not fully utilized at higher resolutions, where the GPU becomes the limiting factor. Conversely, the GPU’s mid-range performance holds back the combo at 4K, preventing it from reaching the top tier.

The nearest rival combos are not listed, but the individual component rankings provide context. The CPU’s average score is 0.1% higher than the Intel Core i7-12700F and 0.3% higher than the AMD Ryzen 9 5980HX, indicating that it is a top-tier processor. The GPU’s average score is 0.7% higher than the RX 6800 and 1% lower than the HD 7950, placing it in the upper-middle range. The combo’s rank of 946 suggests that other pairings with stronger GPUs, such as those with the RX 6800 or higher, would likely achieve better results in Downfall, especially at 4K. The data indicates that the 7800X3D is not the limiting factor; rather, the RX 6700 XT is the component that prevents the combo from climbing higher in the rankings.

Measured FPS Breakdown

The following table lists all measured average frame rates for the combo across three resolutions and four settings:

| Resolution | Settings | Avg FPS |

|------------|----------|---------|

| 3840x2160 | High | 70.5 |

| 3840x2160 | Low | 99.6 |

| 3840x2160 | Medium | 82.2 |

| 3840x2160 | Ultra | 40.6 |

| 2560x1440 | High | 111.9 |

| 2560x1440 | Low | 165.9 |

| 2560x1440 | Medium | 133.2 |

| 2560x1440 | Ultra | 71.1 |

| 1920x1080 | High | 152.2 |

| 1920x1080 | Low | 229.8 |

| 1920x1080 | Medium | 189.6 |

| 1920x1080 | Ultra | 94.3 |

The highest frame rate is 229.8 FPS at 1080p Low, while the lowest is 40.6 FPS at 4K Ultra. At 1080p, all settings exceed 94 FPS, with Ultra at 94.3 FPS, which is comfortably above the 60 FPS threshold for smooth gameplay. At 1440p, High and Medium deliver 111.9 and 133.2 FPS respectively, while Low reaches 165.9 FPS and Ultra drops to 71.1 FPS. At 4K, only Low and Medium exceed 60 FPS, with 99.6 and 82.2 FPS respectively; High is at 70.5 FPS, and Ultra falls to 40.6 FPS. The data shows that the combo can handle 4K with reduced settings, but Ultra is not playable at that resolution.

Settings Recommendations

Based on the measured rows, the High preset offers the best balance of visual quality and performance across all resolutions. At 1080p, High delivers 152.2 FPS, which is well above the 60 FPS target and provides a smooth experience. At 1440p, High achieves 111.9 FPS, still above 60 FPS, and at 4K it maintains 70.5 FPS, which is playable. Medium settings provide higher frame rates—189.6 FPS at 1080p, 133.2 FPS at 1440p, and 82.2 FPS at 4K—but the visual fidelity is lower. Ultra settings are only viable at 1080p (94.3 FPS) and 1440p (71.1 FPS), but at 4K they drop to 40.6 FPS, which is below the playable threshold.

For users prioritizing frame rate over visual quality, Low settings deliver the highest performance, with 229.8 FPS at 1080p, 165.9 FPS at 1440p, and 99.6 FPS at 4K. However, the High preset is recommended as the default because it provides a substantial improvement in visual quality while still maintaining above 60 FPS at all resolutions. The data indicates that the combo is best suited for 1080p and 1440p gaming, where High or Medium settings yield excellent results. At 4K, users should select Low or Medium to stay above 60 FPS, and avoid Ultra entirely. The measured FPS breakdown shows that the RX 6700 XT is the limiting factor at 4K, so adjusting settings to reduce GPU load is the most effective way to maintain playable frame rates.
