Downfall

The AMD Ryzen 9 7900X paired with the NVIDIA GeForce RTX 3080 delivers a robust performance profile in Downfall, a 2016 horror title. The measured data shows this combination is capable of high frame rates across all tested resolutions and settings, though the scaling patterns reveal distinct bottlenecks depending on the workload. The dataset provides a clear picture of how the CPU’s strong multi-threaded performance and the GPU’s substantial bandwidth interact with the game’s rendering demands.

Resolution Scaling

The frame rate progression from 1080p to 4K clearly illustrates the shifting balance between CPU and GPU limitations. At 1920x1080 with Low settings, the combo achieves 299 FPS, which drops to 214 FPS at 2560x1440 and further to 133 FPS at 3840x2160. This represents a 55.5% reduction from 1080p to 4K at Low settings, suggesting that the GPU is already becoming a limiting factor even at lower resolutions, though the CPU’s 12 cores and 24 threads keep the upper ceiling high.

The Medium settings row shows a similar trend: 245 FPS at 1080p, 175 FPS at 1440p, and 109 FPS at 4K. The drop from 1080p to 1440p is 28.6%, while the drop from 1440p to 4K is 37.7%. This escalating decline indicates that as pixel count increases, the RTX 3080’s 10 GB of GDDR6X memory and 760.3 GB/s bandwidth become more stressed, while the CPU’s headroom remains largely untapped.

For High settings, the pattern becomes more pronounced: 201 FPS at 1080p, 143 FPS at 1440p, and 89 FPS at 4K. The percentage drops are 28.9% and 37.8% respectively. The fact that 4K High still yields 89 FPS shows the GPU can handle the load, but the scaling curve suggests that the game’s visual effects at High settings amplify the GPU’s workload disproportionately compared to Medium.

Ultra settings present the steepest curve: 125 FPS at 1080p, 90 FPS at 1440p, and 56 FPS at 4K. The 1080p to 1440p drop is 28.0%, and the 1440p to 4K drop is 37.8%. This consistent ~28% and ~38% pattern across all settings indicates that resolution scaling is highly regular in Downfall, with the GPU being the primary constraint at higher pixel counts. The CPU’s role diminishes as resolution rises, evidenced by the fact that even at 1080p Ultra, the 125 FPS result is far below the 299 FPS Low ceiling, showing the GPU’s rasterization limits rather than any CPU bottleneck.

FAQ

Q: What is the maximum average frame rate achievable with this combo?

A: The highest measured average is 299 FPS at 1920x1080 with Low settings. This is the only result approaching the 300 FPS threshold, indicating that the CPU can feed the GPU sufficiently at lower graphical loads.

Q: How does the RTX 3080 perform at 4K Ultra in this game?

A: The average frame rate at 3840x2160 Ultra is 56 FPS. This is the lowest result in the dataset, and while playable, it demonstrates that the GPU is heavily taxed by the combination of 4K resolution and maximum settings.

Q: Is the CPU a bottleneck at 1080p?

A: At 1080p Low, the 299 FPS result suggests the CPU can push very high frame rates. However, the drop to 201 FPS at High and 125 FPS at Ultra shows the GPU becomes the limiting factor as settings increase, meaning the CPU is not the primary constraint even at 1080p.

Q: What is the frame time consistency like?

A: Only the Medium settings rows include min and max FPS data. At 1080p Medium, the range is 208-282 FPS (average 245); at 1440p Medium, it is 149-201 FPS (average 175); and at 4K Medium, it is 92-125 FPS (average 109). The spread is relatively narrow, suggesting stable performance.

Q: How does the combo rank among all tested configurations?

A: The combination ranks 1057 out of 3716 tested combos for Downfall, placing it in the upper 28.4% of all configurations. This indicates strong but not top-tier performance relative to the full database.

Q: Does the GPU’s memory capacity affect 4K performance?

A: The RTX 3080 has 10 GB of GDDR6X memory. At 4K, the average FPS ranges from 56 (Ultra) to 133 (Low), with the 4K Medium result of 109 FPS showing no signs of memory capacity stalling, though the bandwidth of 760.3 GB/s is likely the more relevant factor.

GPU Role

The NVIDIA GeForce RTX 3080 is built on the Ampere architecture with a GA102 chip, featuring 8704 shading units and 96 ROPs. Its clock speeds are listed as a base of 1440 MHz and a boost of 1710 MHz, with memory running at 1188 MHz (19 Gbps effective). The 10 GB GDDR6X memory pool operates over a 320-bit bus, yielding a bandwidth of 760.3 GB/s. These specs directly influence the measured results in Downfall.

The texture rate of 465.1 GTexel/s and pixel rate of 164.2 GPixel/s are critical for a horror game that likely relies on detailed environments and lighting effects. The data shows that the GPU scales predictably with resolution: at 4K Ultra, the 56 FPS average is a 55.2% drop from the 125 FPS at 1080p Ultra. This aligns with the 4x pixel increase, though the actual drop is less severe, indicating some efficiency in the Ampere design.

The GPU’s FP32 performance of 29.77 TFLOPS is substantial, but Downfall appears to be more memory-bandwidth sensitive. The jump from 1080p Medium (245 FPS) to 4K Medium (109 FPS) is a 55.5% reduction, closely mirroring the pixel count increase. This suggests the 760.3 GB/s bandwidth is being fully utilized at higher resolutions, and any additional memory capacity would not overcome this limitation.

The RTX 3080’s percentile rank of 68 among all GPUs, with an average benchmark score of 23172, places it in the upper tier, but its nearest rivals include the AMD Radeon RX 6600M (deltaPct -0.4) and AMD Radeon R9 M290X (deltaPct -0.4), showing that synthetic scores do not always translate to gaming performance. In Downfall, the 4K Medium result of 109 FPS is respectable, but the Ultra setting drops below 60 FPS, which is a clear indicator of the GPU’s limits at maximum graphical fidelity.

Measured FPS Breakdown

At 1920x1080, the combo delivers a wide range of averages: 299 FPS on Low, 245 FPS on Medium, 201 FPS on High, and 125 FPS on Ultra. The Medium setting also shows min and max values of 208 and 282 FPS, respectively, indicating a 74 FPS spread. The progression from Low to Ultra shows a 58.2% reduction in frame rate, with the largest single drop occurring between High and Ultra (37.8%).

At 2560x1440, the averages are 214 FPS (Low), 175 FPS (Medium), 143 FPS (High), and 90 FPS (Ultra). The Medium result includes a min of 149 FPS and max of 201 FPS, a 52 FPS range. The drop from Low to Ultra is 57.9%, nearly identical to the 1080p pattern, confirming that settings scaling is consistent regardless of resolution.

At 3840x2160, the averages are 133 FPS (Low), 109 FPS (Medium), 89 FPS (High), and 56 FPS (Ultra). The Medium min and max are 92 and 125 FPS, respectively, a 33 FPS spread. The reduction from Low to Ultra is 57.9%, again matching the other resolutions. This uniformity suggests that Downfall applies settings changes in a linear fashion, with no resolution-specific optimizations or bottlenecks.

The 4K Ultra result of 56 FPS is the only average below 60 FPS in the entire dataset. Even at 1440p Ultra, the 90 FPS average is comfortably above the 60 FPS threshold. This indicates that the RTX 3080 can handle most configurations in Downfall with ease, but 4K Ultra pushes it to its limits.

Settings Recommendations

Based on the measured data, the optimal balance of visual quality and frame rate is achieved at 2560x1440 with High settings. This yields 143 FPS on average, which is 78.3% higher than the 4K High result (89 FPS) and only 20.3% lower than the 1080p High result (201 FPS). The 1440p High configuration provides a substantial resolution upgrade over 1080p while maintaining a frame rate well above typical high-refresh-rate monitors.

For users prioritizing maximum smoothness, 1080p Medium offers 245 FPS, which is only 18.1% lower than the Low setting’s 299 FPS but with significantly better visuals. The Medium setting also has the most complete data, with min/max values showing consistency, making it a reliable choice. The jump from Medium to High at 1080p costs 44 FPS (18.0% reduction), which may not justify the visual improvement for competitive play.

At 4K, the Medium setting provides 109 FPS, which is the best balance for 4K displays. The High setting drops to 89 FPS, a 18.3% reduction, while Ultra falls to 56 FPS, which is below the 60 FPS threshold. The data suggests that 4K Medium is the sweet spot for this GPU, as it maintains a playable frame rate while allowing the 10 GB memory and 320-bit bus to operate efficiently.

The Ultra preset is only recommended at 1080p, where the 125 FPS average is still high. At 1440p Ultra, the 90 FPS average is acceptable but the 28% drop from High is significant. The 4K Ultra result of 56 FPS is the only configuration that risks stuttering on standard displays, making it unsuitable for most users.

CPU Role

The AMD Ryzen 9 7900X is a 12-core, 24-thread processor based on the Zen 4 architecture (Raphael) built on a 5 nm process. Its base clock is 4.70 GHz with a boost clock of 5.60 GHz, and it features 64 MB of shared L3 cache. The CPU’s benchmarks show strong multi-threaded performance: a Cinebench R23 multicore score of 29300 and a Geekbench multicore score of 19267. Its single-thread scores are also notable, with Cinebench R23 singlecore at 2016.5 and Geekbench singlecore at 2617.

In Downfall, the CPU’s role is primarily to feed the GPU with draw calls and physics calculations. The 1080p Low result of 299 FPS demonstrates that the 7900X can handle high frame rates without bottlenecking, as the 24 threads provide ample capacity for the game’s engine. The 3DMark 16-thread score of 10972 and max-thread score of 12536 indicate that the CPU scales well with parallel workloads, which is beneficial for a horror game that may use multiple threads for AI and environmental effects.

The CPU’s percentile rank of 91 among all CPUs, with an average benchmark score of 53288, places it in the top 9% of processors. Its nearest rival, the AMD EPYC 7313P, has a deltaPct of 0.2, indicating near-parity in synthetic tests. However, the 7900X’s high single-thread performance (Passmark single-thread score of 4238) is crucial for games that rely on a primary rendering thread, and the data shows no CPU-induced frame drops even at the highest frame rates.

The memory bandwidth of 83.2 GB/s and dual-channel DDR5 support are adequate for the game’s needs, as the measured FPS does not show any stutter or inconsistency that would indicate memory pressure. The CPU’s 170 W TDP and 5 nm process node allow it to maintain high clocks without thermal throttling, which is important for sustained performance in longer gaming sessions. Overall, the 7900X provides more than enough computational power for Downfall, and the GPU is the definitive limiting factor in most scenarios.

How This Combo Ranks

The AMD Ryzen 9 7900X + NVIDIA GeForce RTX 3080 combination ranks 1057 out of 3716 tested combos in Downfall, placing it in the 71.6th percentile of all configurations. This ranking reflects a strong but not elite performance tier, consistent with the CPU’s 91st percentile and GPU’s 68th percentile individually. The combo’s position suggests that while the CPU is top-tier, the GPU holds it back from the highest ranks.

The GPU’s nearest rivals in synthetic benchmarks include the AMD Radeon RX 6600M (deltaPct -0.4) and AMD Radeon R9 M290X (deltaPct -0.4), which are notably weaker cards in real-world gaming. This discrepancy highlights that the RTX 3080’s average benchmark score of 23172 may not fully capture its gaming strengths, as the measured FPS in Downfall shows it outperforming what those synthetic scores would suggest.

Comparing to the CPU’s rivals, the Intel Core i7-14700F (deltaPct -0.6) and Intel Xeon 634 (deltaPct 0.6) are close in synthetic performance, but the 7900X’s higher boost clock and 5 nm node give it an edge in gaming workloads. The combo’s rank of 1057 indicates that there are 1056 configurations that perform better, likely featuring higher-end GPUs like the RTX 3090 or RX 6900 XT, which are absent from this dataset.

The rank also implies that the combo is in the top 28.4% of all tested systems, which is a solid result for a mid-to-high-end pairing. The data shows that the 7900X is not the limiting factor, as even the lowest FPS result (56 at 4K Ultra) is well above typical playability thresholds. If a user were to pair this CPU with a stronger GPU, the rank would likely improve, but as configured, the combo delivers excellent performance for Downfall across all resolution and settings combinations.
