Downfall

The AMD Ryzen 7 5800XT and AMD Radeon RX 6750 XT pairing delivers a fascinating performance profile in Downfall, a 2016 horror title. The data reveals a system that is heavily influenced by graphics settings and resolution, with the CPU demonstrating significant headroom at lower resolutions. This analysis breaks down the measured frame rates to understand where the bottleneck lies and how to optimize the experience.

Resolution Scaling

The transition from 1080p to 4K creates a dramatic shift in performance, clearly illustrating the growing load on the GPU. At Low settings, the average frame rate drops from 239.6 FPS at 1920x1080 to 108.6 FPS at 3840x2160, a reduction of over 54%. This steep decline indicates that even at the lowest graphical fidelity, the Radeon RX 6750 XT is the primary limiting factor as pixel count increases.

Moving to High settings, the scaling is similarly pronounced. The system produces 163.3 FPS at 1080p but falls to 72.7 FPS at 4K. The gap between resolutions is substantial, suggesting that the GPU's rendering pipeline is saturated by the 4K workload. The Ultra preset shows the most severe drop, going from 103 FPS at 1080p to just 47.5 FPS at 4K, which is a 54% performance loss and pushes the experience below the 60 FPS threshold.

Interestingly, the scaling from 1440p to 4K is more aggressive than from 1080p to 1440p. For instance, on Medium settings, the frame rate drops from 137.9 FPS at 2560x1440 to 84.9 FPS at 4K, a 38% decrease. The pattern across all settings points to a GPU that is progressively overwhelmed by the pixel throughput required at 4K, making 1440p the sweet spot for maintaining high refresh rates while preserving visual fidelity.

GPU Role

The Radeon RX 6750 XT's specifications directly explain its performance ceiling in Downfall. With 12 GB of GDDR6 memory on a 192-bit bus delivering 432.0 GB/s of bandwidth, the card has ample resources for this title's textures and assets. The 40 ray accelerators and 2560 shading units are kept busy, but the card's clock speeds—a boost clock of 2600 MHz and a game clock of 2495 MHz—are the key to its frame rate output.

The GPU's 13.31 TFLOPS of FP32 compute power is evidently sufficient for high-refresh 1080p and 1440p gaming, as evidenced by the 239.6 FPS result at Low 1080p. However, the data shows that the card's raw throughput is taxed heavily at 4K. The Ultra preset at 4K produces only 47.5 FPS, which is a clear sign that the combination of higher resolution and intensive effects (likely including ray tracing or heavy post-processing) exceeds the GPU's comfortable operating range.

The measured results align with the GPU's 79th percentile ranking among all tested GPUs. It is not a flagship part, and the benchmarks indicate it performs best when not pushed to absolute extremes. The 47.5 FPS at 4K Ultra is a definitive indicator that the GPU, while capable, requires settings adjustments to deliver a smooth experience at that resolution.

How This Combo Ranks

In the grand scheme of Downfall testing, this CPU-GPU combination holds the 818th rank out of 1741 tested combos. This places it in the upper-middle tier of all possible pairings, suggesting it is a competent but not top-tier setup for this specific game. The data implies that while it outperforms a large portion of configurations, there are a significant number of faster combos that achieve higher frame rates.

The ranking is a product of both components. The CPU's 86th percentile ranking among all CPUs is a strong indicator of its processing power, yet the GPU's 79th percentile suggests it is the slightly weaker link in this pairing. In a game like Downfall, the combo's rank is largely dictated by the GPU's ability to keep up with the CPU's instructions, particularly at higher resolutions where the graphics card becomes the bottleneck.

This mid-tier ranking means users should not expect top-tier 4K performance. Instead, the data suggests this combo is optimized for 1440p and 1080p gaming, where it can leverage its strengths. The gap between the CPU's potential and the GPU's delivery is evident when comparing the 173.7 FPS at 1440p Low to the 70.9 FPS at 1440p Ultra, showing that the GPU's workload is the deciding factor in overall rank.

Settings Recommendations

Based on the measured frame rates, the High preset offers the most balanced experience across all resolutions. At 1080p, it delivers 163.3 FPS, which is well above the threshold for smooth gameplay and only slightly below the 198.9 FPS of Medium. At 1440p, High produces 113.2 FPS, a fantastic result that takes full advantage of higher refresh rate monitors. Even at 4K, High maintains 72.7 FPS, which is playable and significantly smoother than the 47.5 FPS of Ultra.

The Ultra preset is not recommended for 4K gaming, as the 47.5 FPS average dips below the generally accepted 60 FPS standard for a smooth experience. While it is playable at 1440p with 70.9 FPS, the performance cost compared to High is substantial. The jump from High to Ultra at 1440p costs over 42 FPS, a 37% reduction in performance for what is likely a marginal visual improvement.

For users prioritizing maximum frame rates, the Low preset at 1080p yields an impressive 239.6 FPS, which is ideal for competitive play. However, for the best visual experience without sacrificing fluidity, the High preset at 2560x1440 is the clear winner. It provides a high level of detail while maintaining an average frame rate of 113.2 FPS, making it the recommended configuration for this hardware.

Measured FPS Breakdown

At 1920x1080, the system shows remarkable strength. The Low preset achieves an average of 239.6 FPS, while Medium hits 198.9 FPS. High follows with 163.3 FPS, and Ultra brings up the rear with 103 FPS. These numbers show that at 1080p, the CPU is doing a significant amount of work, allowing the GPU to push very high frame rates.

Moving to 2560x1440, the GPU begins to feel the pressure. Low still produces a rapid 173.7 FPS, and Medium drops to 137.9 FPS. The High preset delivers a solid 113.2 FPS, but Ultra falls to 70.9 FPS. This resolution represents a good balance, with even the High preset offering more than double the frame rate of the 4K Ultra setting.

Finally, at 3840x2160, the GPU is clearly the limiting factor. Low settings yield 108.6 FPS, which is still playable, but Medium drops to 84.9 FPS. The High preset manages 72.7 FPS, while Ultra craters to 47.5 FPS. The data shows a clear hierarchy: 1080p is for maximum FPS, 1440p for the best balance, and 4K is only viable with lower settings.

CPU Role

The AMD Ryzen 7 5800XT is a powerhouse that is not fully utilized in Downfall. With 8 cores and 16 threads based on the Zen 3 architecture, its processing capability is substantial. The CPU's 3.80 GHz base clock and 4.80 GHz boost clock provide the speed necessary to feed the GPU, and its strong synthetic scores—like 23,794 in Cinebench R23 multi-core and 3,359 in single-core—confirm its high performance.

The data suggests the CPU is not the bottleneck in this configuration. At 1080p, the system achieves 239.6 FPS on Low, a rate that is rarely CPU-limited in modern games. The fact that performance scales down so significantly as resolution increases points to the GPU being the primary constraint. The CPU's 86th percentile ranking and its average benchmark score of 29,774 show it is a top-tier processor that has ample headroom.

This is further evidenced by the nearest rival comparisons. The CPU is within 0.3% of the AMD Ryzen 7 6800HS and the AMD Ryzen 7 7840H, indicating it is on par with other high-end processors. In Downfall, the CPU's role is to ensure frame times are consistent and to avoid introducing stutters, which it does effectively by maintaining high minimum frame rates, as evidenced by the consistently high average FPS across all settings.
