Downfall

The AMD Ryzen 7 7800X3D paired with the NVIDIA GeForce RTX 4080 delivers a dominant performance profile in Downfall, a 2016 horror title that scales aggressively with both CPU and GPU resources. The measured data shows this combo is capable of extreme frame rates, often exceeding the refresh rates of standard high-end monitors, even at demanding 4K resolutions. The analysis below breaks down how this specific CPU-GPU pairing behaves across resolutions and settings, using the measured FPS data to determine where the bottleneck lies and how to optimize the experience.

Resolution Scaling

The frame rate scaling from 1080p to 4K reveals a classic shift in system limitation. At 1920x1080 with Low settings, the combo produces an average of 400 FPS. When moving to 2560x1440 at Low, that figure drops to 285 FPS, a significant 28.75% reduction. The scaling continues to 3840x2160 at Low, where the average settles at 178 FPS, another 37.5% drop from the 1440p figure. This pattern indicates that at lower resolutions, the system is heavily CPU-bound; the Ryzen 7 7800X3D’s eight cores and 96 MB of shared L3 cache are feeding frames as fast as possible, but the GPU is not yet saturated.

The bottleneck shifts more toward the GPU as resolution increases. At Medium settings, the 1080p average is 327 FPS, which drops to 233 FPS at 1440p (a 28.7% decrease) and then to 145 FPS at 4K (a 37.8% decrease from 1440p). The percentage drops are consistent, but the absolute frame rates are lower than at Low settings, suggesting the GPU is starting to take on more work. However, the real indicator of the GPU’s ceiling emerges at High and Ultra presets. At High settings, the average goes from 268 FPS at 1080p to 191 FPS at 1440p (a 28.7% drop) and then to 119 FPS at 4K (a 37.7% drop). The scaling is nearly identical to the Medium preset, indicating the GPU is increasingly the limiting factor, but the CPU still has headroom.

The Ultra preset tells the clearest story about the GPU’s limits. At 1080p Ultra, the combo produces 168 FPS. At 1440p Ultra, it drops to 120 FPS (a 28.6% reduction). At 4K Ultra, the average falls to 74 FPS, a massive 38.3% drop from 1440p. This final drop is the largest relative decline across all settings, and it signals that the RTX 4080 is now the primary bottleneck. The data suggests that while the CPU remains capable of pushing high frame rates even at 4K, the GPU’s rendering load at Ultra settings becomes the dominant constraint, especially as pixel count increases. The pattern is clear: below 4K, the Ryzen 7 7800X3D keeps the GPU well-fed, but at 4K with high fidelity settings, the RTX 4080's limits become the defining factor.

GPU Role

The NVIDIA GeForce RTX 4080 is the workhorse for pixel pushing in Downfall, and its specifications explain the scaling behavior seen in the resolution analysis. The GPU features 16 GB of GDDR6X memory on a 256-bit bus, providing a bandwidth of 716.8 GB/s. This memory capacity and bandwidth are more than sufficient for a 2016 title, meaning VRAM capacity is not a limiting factor at any resolution tested. The card’s architecture is Ada Lovelace, built on a 5 nm process, with 9728 shading units and 112 ROPs. These specifications translate to high raw throughput, which is evident in the frame rates observed.

The clocks are another key factor. The base clock is 2205 MHz, with a boost clock of 2505 MHz. These high frequencies allow the GPU to execute the rendering pipeline quickly, which is crucial for maintaining high averages in Downfall. The 48.74 TFLOPS of FP32 compute power provides ample headroom for the game's graphical effects. The data shows that at 4K Ultra, the GPU is clearly the limiting factor, as the average FPS drops to 74, which is less than half of what it achieves at 1080p Ultra (168 FPS). This indicates that the RTX 4080's raw compute and memory bandwidth are being fully utilized at that resolution and preset.

The GPU's performance relative to its peers is telling. The nearest rival in the benchmark database is the NVIDIA GeForce RTX 4080 SUPER, which has an average benchmark score of 54209, a delta of just 0.1% from the RTX 4080's score of 54247. This means the RTX 4080 is virtually identical in performance to its SUPER variant in synthetic tests. The other rivals, such as the AMD Radeon Pro W5700X, are slightly behind, with a delta of -1.1%. This positioning confirms that the RTX 4080 is a top-tier card, and its performance in Downfall aligns with its high percentile ranking of 86 among all GPUs. The GPU's role is to deliver the high frame rates seen at 1080p and 1440p, and to provide a playable experience at 4K, even if the Ultra preset pushes it to its limits.

CPU Role

The AMD Ryzen 7 7800X3D is the central processor in this combo, and its specifications are uniquely suited for gaming. It has 8 cores and 16 threads, with a base clock of 4.20 GHz and a boost clock of 5.00 GHz. The architecture is Zen 4, built on a 5 nm process, and it features a massive 96 MB of shared L3 cache. This large cache is the X3D hallmark, and it is critical for gaming performance because it allows the CPU to store more game data closer to the cores, reducing latency and improving frame pacing. The CPU's average benchmark score is 33079, placing it in the 83rd percentile of all CPUs.

The CPU's performance is best understood through its synthetic benchmarks. In Cinebench R23, it scores 16817 points in multicore and 1713 points in singlecore. These numbers are strong, but the real story is in the gaming-specific tests. The 3DMark scores are particularly relevant: it achieves 7980 points with 16 threads and 959 points with a single thread. The single-thread score is crucial for older games like Downfall, which often rely on a few fast cores. The high boost clock of 5.00 GHz ensures that the CPU can deliver excellent single-thread performance, which is reflected in the high frame rates at 1080p.

The data shows that the CPU is not the bottleneck at any resolution in Downfall. At 1080p Low, the combo hits 400 FPS, which is likely near the CPU's practical limit for frame generation. Even at 4K Low, the average is 178 FPS, indicating the CPU has more than enough headroom to keep up with the GPU. The Ryzen 7 7800X3D's nearest rivals in the database are the AMD Ryzen 7 8700G and the Intel Core i7-13650HX, both with an average score of 33089, a 0% delta. The AMD Ryzen 9 PRO 6950H is slightly ahead at 33201, a -0.4% delta, which is negligible. This shows the 7800X3D is at the top of its class, and its performance in Downfall confirms that it can drive even a high-end GPU like the RTX 4080 without holding it back.

Measured FPS Breakdown

The measured FPS data provides a comprehensive view of the combo's performance across all settings and resolutions. At 1920x1080, the lowest resolution tested, the combo achieves exceptional frame rates. The Low preset yields an average of 400 FPS, which is the highest average recorded in the entire dataset. The Medium preset drops to 327 FPS, with a minimum of 278 FPS and a maximum of 376 FPS, indicating smooth performance. The High preset produces 268 FPS, and the Ultra preset yields 168 FPS. These numbers show that at 1080p, the combo is more than capable of driving any high-refresh-rate monitor to its maximum potential, regardless of settings.

Moving to 2560x1440, the frame rates remain very high. The Low preset produces an average of 285 FPS. The Medium preset averages 233 FPS, with a minimum of 198 FPS and a maximum of 268 FPS. The High preset yields 191 FPS, and the Ultra preset drops to 120 FPS. The drop from 1080p to 1440p is consistent across all settings, around 28-29%, which indicates that the GPU is scaling as expected with the increased pixel count. At this resolution, the combo still delivers excellent performance, with even the Ultra preset maintaining an average above 120 FPS, which is ideal for 144Hz monitors.

At 3840x2160, the performance is still strong but shows the GPU's limits. The Low preset averages 178 FPS, which is impressive for 4K. The Medium preset averages 145 FPS, with a minimum of 123 FPS and a maximum of 167 FPS. The High preset averages 119 FPS, and the Ultra preset averages 74 FPS. The minimum FPS data is only available for the Medium preset at each resolution, and at 4K Medium, the minimum of 123 FPS suggests there are occasional dips, but the average remains high. The Ultra preset at 4K is the only setting that falls below the 100 FPS threshold, indicating that this is the most demanding configuration. The data shows a clear hierarchy: 1080p is the sweet spot for maximum frame rates, 1440p offers a great balance of fidelity and speed, and 4K is playable but requires dropping to High settings or lower to maintain a smooth experience.

How This Combo Ranks

The AMD Ryzen 7 7800X3D and NVIDIA GeForce RTX 4080 combination ranks 230 out of 3716 tested combos in Downfall. This places it in the top 6.2% of all configurations tested, which is a strong showing for a high-end pairing. The rank reflects the combined strength of both components. The CPU's 83rd percentile ranking and the GPU's 86th percentile ranking suggest that both are near the top of their respective fields, and when combined, they produce a system that is faster than the vast majority of others.

The rank is particularly impressive considering the game's age. A 2016 title like Downfall may not be optimized for modern hardware, but this combo still manages to achieve top-tier performance. The high rank is likely due to the CPU's excellent single-thread performance, which is crucial for older game engines, and the GPU's raw power, which handles the graphical load easily at most settings. The data indicates that this combo is not just good, but exceptional, placing it in the upper echelon of all possible configurations for this game. The fact that it is ranked 230 out of 3716 means that only a small fraction of systems can outperform it, and those likely feature even more expensive or newer components. For most users, this combo represents a ceiling of performance that is rarely exceeded.

Settings Recommendations

Based on the measured FPS data, the best experience depends on the user's display and preference for frame rate versus visual fidelity. For users with 1080p displays, the Ultra preset is the clear choice. The average of 168 FPS is well above the 144Hz refresh rate of many gaming monitors, and the drop from High to Ultra is only 100 FPS, showing that the GPU has plenty of headroom. Even at Ultra, the frame rate is high enough to ensure a smooth, responsive experience. There is no need to sacrifice visual quality at this resolution.

For 1440p displays, the High preset offers the best balance. The average of 191 FPS is excellent for high-refresh-rate monitors, and it is significantly higher than the 120 FPS achieved at Ultra. The jump from High to Ultra costs 71 FPS, which is a substantial loss for a visual improvement that may be subtle in a horror game. The Medium preset also performs well at 233 FPS, but High provides a better visual experience without a significant performance penalty. The data suggests that High is the sweet spot at 1440p, delivering high frame rates and good fidelity.

For 4K displays, the High preset is the recommended choice. The average of 119 FPS is just below the 120 FPS threshold, which is generally considered the minimum for smooth gameplay on high-refresh-rate displays. The Medium preset offers 145 FPS, which is more comfortable, but the visual quality drop from High to Medium may be noticeable. The Ultra preset at 74 FPS is not recommended, as it falls below the 60 FPS minimum for a playable experience and shows a significant performance hit. The data indicates that High is the best compromise for 4K, providing a playable frame rate with good visual fidelity. For those who prioritize frame rate above all else, the Low preset at 178 FPS is an option, but it sacrifices too much visual quality for a marginal gain. Overall, the High preset is the most versatile recommendation across all resolutions, but the specific choice should be guided by the display's refresh rate and the user's tolerance for visual compromises.
