Downfall

The AMD Ryzen 9 7900X and NVIDIA GeForce RTX 5080 combination delivers exceptionally high frame rates in Downfall, a horror title that clearly favors raw GPU throughput. The data shows that this pairing is not merely sufficient for smooth gameplay but is so overpowered that it saturates even the most demanding presets at 4K. This analysis examines the measured performance, contextualizes it against comparable hardware, and determines the optimal settings for a consistent 60 FPS experience across the three primary resolutions.

Similar Performance Alternatives

The benchmark data places this CPU and GPU pairing in a fascinating position relative to their nearest rivals. The AMD Ryzen 9 7900X, with an average benchmark score of 53,288, sits within a tightly clustered group of processors. The closest competitor is the AMD EPYC 7313P, which scores 53,206, a mere 0.2% difference. This effectively means that in CPU-bound scenarios, the 7900X and EPYC 7313P would deliver nearly indistinguishable performance. The Intel Xeon Phi 7290 is marginally ahead at 53,469, a 0.3% delta, while the Intel Xeon 634 trails closely at 52,974 (0.6% slower). The Intel Core i7-14700F is the fastest of the group at 53,620, but only by a 0.6% margin over the 7900X. These sub-1% variations suggest that swapping the 7900X for any of these alternatives would yield no perceptible change in Downfall's frame rates, as the game is unlikely to be CPU-limited at the tested settings.

On the GPU side, the RTX 5080's average benchmark score of 56,083 places it in a similar situation, though with a slightly wider spread. The AMD Radeon 8060S (55,757) and AMD Radeon RX 6750 GRE 12 GB (55,698) are the closest neighbors, trailing by 0.6% and 0.7% respectively. The AMD Radeon Pro W5700X is further behind at 54,828, a 2.3% deficit. Interestingly, the AMD Radeon RX 9070 GRE is the only rival that is faster, scoring 57,367, which is 2.2% ahead of the RTX 5080. For Downfall, a user with an RX 9070 GRE would see slightly higher frame rates, but the difference would be small enough to be imperceptible in real-world gameplay. The practical takeaway is that the RTX 5080's performance class is well-defined, with several AMD alternatives offering statistically equivalent performance in this title.

Best Settings per Resolution

The measured FPS data reveals that the RTX 5080 has ample headroom at every resolution, allowing the most visually demanding preset to be used while maintaining frame rates far above the 60 FPS playability threshold. At 1920x1080, the Ultra preset delivers an average of 180.7 FPS. This is the clear recommendation, as it provides the highest visual fidelity without any performance compromise. At 2560x1440, the Ultra preset again is the best choice, with an average of 127.6 FPS. The frame rate remains exceptionally high, ensuring a fluid experience on high-refresh-rate monitors. At 3840x2160, the Ultra preset is still viable, producing an average of 79.2 FPS. Although this is the lowest average FPS recorded, it remains comfortably above the 60 FPS threshold, making Ultra the recommended setting for 4K as well.

The data suggests that there is no scenario where a user must downgrade from Ultra to maintain playability. The gap between Ultra and the next lower preset, High, is substantial at 4K (79.2 FPS vs 125.7 FPS), but the Ultra preset's performance is sufficient. For those seeking maximum frame rates, the Low preset at 1080p yields 423.6 FPS, but this is unnecessary given the already stellar Ultra performance. The verdict is straightforward: use Ultra settings at all three resolutions for the best balance of visual quality and performance.

CPU and GPU Roles

The performance scaling across resolutions and presets clearly indicates that the GPU is the dominant factor in Downfall's performance, with the CPU playing a minimal role. This is evident from the frame rate progression at any given preset. For example, at the High preset, the average FPS drops from 285.5 at 1920x1080 to 205.6 at 2560x1440, and then to 125.7 at 3840x2160. This 56% reduction in performance from 1080p to 4K is a classic symptom of GPU-bound rendering, where the increasing pixel count directly taxes the graphics card's fill rate and shading units.

The CPU's influence is more pronounced when comparing presets at the same resolution. At 4K, moving from Low to Ultra reduces the average FPS from 186.3 to 79.2, a 57% drop. This is also predominantly a GPU workload, as higher settings increase shader complexity, texture detail, and post-processing effects. The Ryzen 9 7900X, with its 12 cores and 24 threads, is more than capable of feeding the RTX 5080. Its high single-thread performance (3dmark_single_thread score of 1093) ensures that the game's main thread is not a bottleneck, even at 1080p where CPU overhead is typically higher. The data shows that at 1080p Low, the system achieves 423.6 FPS, a figure that would stress even the fastest CPUs, yet the 7900X handles it without issue. Ultimately, the RTX 5080 is the performance limiter, and the CPU's role is to ensure that the GPU is never starved of data, a task the 7900X performs admirably.

The Verdict

Yes, this system can run Downfall exceptionally well at all tested resolutions. The verdict by resolution is clear and unambiguous. At 3840x2160, all four settings (Low, Medium, High, and Ultra) are playable, with the best setting being Ultra at an average of 79.2 FPS. This is a remarkable result, as it means 4K gaming at maximum detail is not only possible but also smooth. At 2560x1440, the Ultra preset is again the best, delivering an average of 127.6 FPS. This performance is ideal for 1440p high-refresh-rate monitors, providing a significant margin over the 60 FPS threshold. At 1920x1080, the Ultra preset produces an average of 180.7 FPS. This is overkill for most 1080p displays, but it ensures that even with V-Sync enabled, the frame rate will never dip below the display's refresh rate. In summary, the PC clears the 60 FPS barrier with the most demanding settings at every resolution, making it an excellent choice for this horror title.

| 1920x1080 | Low | 423.6 |

| 1920x1080 | Medium | 347.4 |

| 1920x1080 | High | 285.5 |

| 1920x1080 | Ultra | 180.7 |

| 2560x1440 | Low | 305.0 |

| 2560x1440 | Medium | 247.9 |

| 2560x1440 | High | 205.6 |

| 2560x1440 | Ultra | 127.6 |

| 3840x2160 | Low | 186.3 |

| 3840x2160 | Medium | 156.8 |

| 3840x2160 | High | 125.7 |

| 3840x2160 | Ultra | 79.2 |

The data shows a consistent and predictable scaling pattern. The frame rate drops by roughly 30-40% when moving from one resolution to the next (e.g., from 1080p to 1440p), and by a similar margin when increasing the preset from Low to Ultra. The only anomaly is the 4K Ultra result, which shows a larger drop from 4K High (125.7 FPS to 79.2 FPS), indicating that the Ultra preset at 4K introduces a particularly heavy workload. However, even this worst-case scenario remains highly playable.
