Downfall

The AMD Ryzen 7 5700X and AMD Radeon RX 7800 XT combination delivers a high-refresh-rate experience in Downfall, but the performance curve reveals a system that is heavily dependent on the graphics preset. The measured data set shows a clear pattern where the GPU becomes the primary bottleneck at higher resolutions, while lower settings at 1080p push frame rates to extremes that suggest the CPU is still holding pace. This analysis breaks down the measured FPS across all resolutions and settings, contextualizes the combo's standing against other tested configurations, and examines the role of the GPU's specifications in these results.

Resolution Scaling

The frame rate drop from 1080p to 4K is substantial and directly illustrates the shift in workload from the CPU to the GPU. At High settings, the average FPS falls from 188.7 at 1920x1080 to 132.5 at 2560x1440, and finally to 81.6 at 3840x2160. This represents a 56.7% reduction in frame rate from the lowest to the highest resolution tested. The scaling is not linear; the drop from 1080p to 1440p is 29.8%, while the drop from 1440p to 4K is 38.4%. This steeper decline at higher resolutions indicates that the GPU is becoming the limiting factor, as the pixel count increases faster than the render workload can be efficiently processed.

At Low settings, the same pattern emerges with even more dramatic numbers. The average FPS at 1080p Low is 277.6, dropping to 202.2 at 1440p and 124.8 at 4K. The absolute difference between 1080p and 4K here is 152.8 FPS, which is a 55% reduction. The fact that Low settings produce such high frame rates at 1080p suggests the CPU has ample headroom, but the GPU still cannot maintain those rates when pixel count rises. Conversely, at Ultra settings, the frame rates are much lower across the board: 116.1 FPS at 1080p, 81.9 at 1440p, and 52.3 at 4K. The scaling from 1080p to 4K at Ultra is a 54.9% drop, very similar to the percentage losses seen at other presets, reinforcing that the GPU is the dominant constraint in all cases.

The data suggests that for this combination, resolution scaling is almost purely a GPU-bound exercise. The CPU, with its 8 cores and 16 threads, appears capable of feeding the GPU at 1080p Low where the frame rate exceeds 277 FPS. However, the sheer pixel throughput required at 4K, regardless of settings, brings the GPU to its knees. The difference between Low and Ultra at 4K is 72.5 FPS (124.8 vs 52.3), which shows that while lowering settings helps, the GPU still cannot overcome the resolution penalty entirely. The limiting component is clearly the RX 7800 XT, as the frame rate scales predictably with resolution and is not flat, which would indicate a CPU bottleneck.

Settings Recommendations

The measured data provides clear guidance on which preset offers the best balance of visual fidelity and performance. At 1080p, all presets are playable, with even Ultra hitting 116.1 FPS. However, the jump from High to Ultra is only a 38.4% reduction in frame rate (188.7 to 116.1), which is a significant cost for presumably marginal visual gains. The Medium preset at 231.2 FPS offers a massive 49.2% performance headroom over High while still providing a substantially better visual experience than Low at 277.6 FPS. For users with a 144Hz monitor, Medium at 1080p is the optimal choice, as it delivers frame rates well above the refresh rate while maintaining a reasonable preset level.

At 1440p, the recommendation shifts. High settings produce 132.5 FPS, which is excellent for a 144Hz display. Ultra drops to 81.9 FPS, which is still playable but misses the high-refresh-rate mark. Medium at 166.2 FPS is the performance sweet spot, offering a 25.4% improvement over High while staying above the 144Hz threshold. Since the GPU is the bottleneck, choosing Medium over High at 1440p is a sensible trade-off, as the frame rate gain is substantial without a catastrophic visual downgrade.

At 4K, the picture is different. Only Low (124.8 FPS) and Medium (102.8 FPS) achieve frame rates above 100. High drops to 81.6 FPS, and Ultra falls to 52.3 FPS, which is below the 60 FPS comfort zone. For a smooth 4K experience, Medium is the highest preset that maintains a playable frame rate, but users targeting 120Hz or higher will need to use Low. The data shows that High at 4K is a poor compromise: it offers only 81.6 FPS, which is a 20.6% reduction from Medium, and the visual difference between High and Medium is often less impactful than the frame rate penalty. The best experience per the measured rows is Medium for most resolutions, with Low reserved for 4K high-refresh-rate displays.

How This Combo Ranks

In the database, this CPU and GPU pairing is ranked 644 out of 1741 tested combinations for Downfall. This places it in the upper third of all combos, indicating a strong but not elite-tier performance. The rank is a composite measure, and given that the measured FPS at 1080p High (188.7) is very high, the ranking likely reflects that many other combinations with more powerful GPUs or newer CPUs achieve even higher frame rates at lower resolutions. However, the 83rd percentile ranking of the CPU and the 76th percentile ranking of the GPU suggest that this combo sits above average in both components, yet the game and its settings can push the GPU beyond its comfort zone.

The combo's rank of 644 out of 1741 means it outperforms roughly 63% of all tested configurations. This is a respectable position, but it is not near the top, which would require a more powerful GPU to handle 4K Ultra settings without dropping below 60 FPS. The data shows that the combo is well-balanced for 1080p and 1440p gaming, where it achieves high frame rates, but it falls behind in the 4K Ultra tier where high-end cards would maintain higher averages. The rank reflects the RX 7800 XT's capability, but also a reminder that it is not a flagship part. The CPU's performance, with a Cinebench R23 multi-core score of 22620, is strong, but the game's engine appears to rely more on the GPU, which limits the combo's overall standing.

Measured FPS Breakdown

The full measured FPS table is as follows:

• 3840x2160: Low 124.8, Medium 102.8, High 81.6, Ultra 52.3
• 2560x1440: Low 202.2, Medium 166.2, High 132.5, Ultra 81.9
• 1920x1080: Low 277.6, Medium 231.2, High 188.7, Ultra 116.1

The progression across settings is consistent at every resolution. Low to Medium yields an average increase of approximately 18% (e.g., 277.6 to 231.2 at 1080p), while High is roughly 18% lower than Medium. Ultra is the most demanding, with a drop of about 38% from High. This pattern is uniform, suggesting that the game's settings have predictable performance costs. The frame rates at 1080p are exceptional, with even Ultra exceeding 116 FPS, making this combo a viable choice for competitive play or high-refresh-rate monitors.

At 1440p, the frame rates are still very high, with Low exceeding 200 FPS, which is rare for many games. The Ultra preset at 81.9 FPS is the only one that falls below the 100 FPS mark, but it remains playable on a 60Hz or 75Hz display. At 4K, the frame rates drop significantly, but the combo still manages to stay above 50 FPS at the highest settings, which proves the GPU's 16 GB of memory and 624.1 GB/s bandwidth. The data shows no min or max FPS values, so the analysis relies solely on averages, but the consistent scaling suggests stable performance without major stutters or frame time spikes.

GPU Role

The AMD Radeon RX 7800 XT is the primary driver of the frame rates seen in these results. With 16 GB of GDDR6 memory on a 256-bit bus, the GPU has ample bandwidth (624.1 GB/s) to handle the texture and geometry data at 4K, but the raw compute power is still finite. The boost clock of 2430 MHz and the game clock of 2124 MHz indicate a high-frequency design, which helps at lower resolutions but cannot overcome the pixel fill rate demands at 4K. The GPU's 3840 shading units and 96 ROPs are responsible for the 233.3 GPixel/s pixel rate, which is a key metric for resolution scaling.

The data shows that the GPU is the bottleneck at all resolutions, as the frame rate changes are directly tied to the preset and resolution rather than CPU performance. The RX 7800 XT's 76th percentile ranking against all GPUs confirms its position as a high-mid-range part. Its average benchmark score of 32619 is close to rivals like the AMD FirePro S9300 X2 (32540) and NVIDIA P104-100 (32747), with deltaPct values of 0.2% and -0.4%, respectively. This indicates that the GPU performs on par with those parts, which are not modern gaming cards but still show the RX 7800 XT's compute capability.

The GPU's VRAM of 16 GB is more than sufficient for Downfall at any resolution, as the game is from 2016 and likely does not require more than 8 GB even at 4K Ultra. However, the memory bandwidth and pixel rate are what limit performance at higher resolutions. The fact that 4K Ultra drops to 52.3 FPS suggests that the GPU is hitting its fill rate limits, not a memory capacity issue. The boost clock of 2430 MHz is high, but the architectural efficiency of RDNA 3.0, with its 28,100 million transistors on a 5 nm process, is what allows it to achieve these frame rates. The GPU's performance in this game is strong, but it is clear that for 4K Ultra at 60 FPS, a more powerful card would be necessary.
