Downfall

The AMD Ryzen 9 9900X3D paired with the AMD Radeon RX 9070 delivers a strong showing in Downfall, a horror title that clearly rewards both high-end CPU and GPU resources. The combo ranks 829th out of 2928 tested combinations, placing it comfortably in the upper third of all systems evaluated. This position reflects a balanced partnership where neither component consistently bottlenecks the other, though the data reveals distinct scaling patterns that shift the workload balance depending on resolution and quality settings.

How This Combo Ranks

The 829th rank out of 2928 combos places this pairing in the 72nd percentile of all tested systems for Downfall. That is a solid result, though not a top-tier one—there are more than 800 combos that achieve higher average frame rates in this game. The ranking suggests that while this hardware is well above average, it does not dominate the leaderboard, likely due to the GPU sitting in a mid-to-upper tier rather than at the absolute flagship level.

The CPU itself ranks in the 91st percentile against all processors, which is a very high standing. The GPU, by contrast, ranks in the 69th percentile against all graphics cards. This creates an interesting dynamic: the processor is clearly the stronger component relative to its peers, while the graphics card is competent but less exceptional. In Downfall, the combination's overall rank falls between these two percentiles, indicating that the GPU's relative weakness pulls the combo down from where the CPU alone would suggest.

Looking at the CPU's nearest rivals, the Ryzen 9 9900X3D posts an average benchmark score of 54762. The Intel Core Ultra 5 245KF scores 55093, a delta of -0.6 percent, meaning the AMD chip is essentially tied with it. The Intel Core Ultra 5 245K scores 54053, putting the 9900X3D 1.3 percent ahead. The Intel Xeon 6505P scores 53701, a 2 percent gap, and the Intel Core i7-14700F scores 53620, a 2.1 percent gap. These are narrow margins, showing that the 9900X3D sits at the top of a very tightly clustered group of high-end desktop processors.

For the GPU, the RX 9070's average benchmark score is 23877. Its nearest rival, the NVIDIA GeForce GTX TITAN Z, scores 23736, a delta of 0.6 percent in favor of the AMD card. The AMD Radeon RX 6800S scores 24063, putting it 0.8 percent ahead of the RX 9070. The NVIDIA GeForce RTX 3080 Mobile scores 23628, a 1.1 percent gap, and the NVIDIA GeForce RTX 2080 SUPER scores 24170, a 1.2 percent gap. Again, the differences are small, placing the RX 9070 in a competitive but not dominant position among its direct peers.

The measured FPS data confirms this mid-upper tier placement. At 1080p Ultra, the combo averages 123 FPS, which is smooth for a horror title. At 4K Ultra, it drops to 55 FPS, which is playable but not ideal for a genre that often benefits from higher frame rates for responsive camera movement. The overall rank of 829 suggests that many other combos, likely featuring faster GPUs, achieve better results, especially at higher resolutions where the graphics card becomes the limiting factor.

GPU Role

The AMD Radeon RX 9070 is built on the RDNA 4.0 architecture, using the Navi 48 chip manufactured on a 4 nm process at TSMC. It packs 3584 shading units, 224 texture mapping units, and 128 raster operation units, along with 56 ray tracing cores. The GPU has a base clock of 1330 MHz, a game clock of 2070 MHz, and a boost clock of 2520 MHz. These clock speeds are substantial, and the boost behavior directly influences the measured FPS in Downfall.

Memory configuration plays a significant role in this game's performance. The RX 9070 comes with 16 GB of GDDR6 memory on a 256-bit bus, providing a bandwidth of 644.6 GB/s. The memory clock runs at 2518 MHz, which translates to 20.1 Gbps effective. For a horror game like Downfall, which often features detailed textures and atmospheric lighting, the 16 GB capacity ensures that even at 4K Ultra settings, the card does not run out of VRAM. The measured FPS at 4K Ultra is 55 FPS, and while this is the lowest result in the dataset, it does not appear to be a VRAM-related crash or stutter—the frame rate is consistent rather than collapsing due to memory pressure.

The GPU's compute capabilities are also relevant. It delivers 36.13 TFLOPS of FP32 performance, with the same figure for FP16 at a 1:1 ratio. The pixel rate is 322.6 GPixel/s, and the texture rate is 564.5 GTexel/s. These raw numbers translate into the ability to handle high-resolution rendering, but the data shows that Downfall at Ultra settings is demanding. The drop from 107 FPS at 4K Medium to 55 FPS at 4K Ultra represents a 48.6 percent decrease, which is a steep penalty for the highest quality preset.

The GPU's benchmark scores further contextualize its role. In 3DMark Steel Nomad DX12, it scores 6290. In Geekbench OpenCL, it scores 131539, and in Vulkan, it scores 58705. Passmark results show a G3D score of 25381 and a GPU compute score of 14737. These numbers align with the GPU's 69th percentile ranking, confirming that it is a capable mid-to-upper range card that can handle Downfall well at most settings but struggles to maintain high frame rates at the absolute maximum quality.

Settings Recommendations

The measured FPS data provides clear guidance on which preset offers the best experience. At 1080p, the Ultra preset delivers 123 FPS, which is smooth and responsive. However, the Medium preset at the same resolution achieves 241 FPS with a minimum of 205 FPS and a maximum of 277 FPS. The jump from Medium to Ultra costs 118 FPS, which is a massive 48.9 percent reduction. For a horror game, where frame pacing and smoothness matter for immersion, the Medium preset at 1080p is the best choice—it provides more than double the frame rate of Ultra while still maintaining good visual quality.

At 1440p, the situation is similar. Ultra averages 88 FPS, which is playable, but Medium averages 172 FPS with a minimum of 146 FPS and a maximum of 198 FPS. The Medium preset again offers a much higher frame rate—nearly double—while the visual difference between Medium and Ultra in a dark, atmospheric title like Downfall may not justify the 84 FPS loss. The High preset at 1440p sits at 141 FPS, which is also excellent, but Medium provides an additional 31 FPS with likely minimal visual sacrifice.

At 4K, the recommendations shift. Ultra drops to 55 FPS, which is borderline for a smooth experience. Medium averages 107 FPS with a minimum of 91 FPS and a maximum of 123 FPS, which is much better. High averages 88 FPS, and Low averages 131 FPS. At 4K, the Medium preset appears to be the sweet spot—it offers a playable frame rate well above 60 FPS, with a minimum that does not dip below 91 FPS. The Ultra preset at 55 FPS is technically playable but may feel less smooth, especially during fast-paced horror sequences where camera movement is critical.

Across all resolutions, the Medium preset consistently provides the best balance of frame rate and visual quality. At 1080p, it delivers 241 FPS; at 1440p, 172 FPS; and at 4K, 107 FPS. The minimum frame rates for Medium are also healthy—205 FPS at 1080p, 146 FPS at 1440p, and 91 FPS at 4K—indicating stable performance without severe drops. For players with high refresh rate monitors, Medium at 1080p or 1440p is the clear winner. For 4K displays, Medium still achieves a triple-digit average, making it the recommended choice for a smooth experience.

Measured FPS Breakdown

The dataset provides 12 measured FPS rows, covering four settings across three resolutions. At 1920x1080, the Low preset averages 295 FPS, which is exceptionally high. The Medium preset averages 241 FPS with a minimum of 205 FPS and a maximum of 277 FPS. The High preset averages 198 FPS, and the Ultra preset averages 123 FPS. The progression from Low to Ultra shows a steady decline: 295 to 241 to 198 to 123. The largest single drop occurs between High and Ultra, a 75 FPS reduction (37.9 percent). This suggests that the Ultra preset introduces significant rendering costs, likely from advanced lighting or shadow effects that are particularly demanding in Downfall.

At 2560x1440, the Low preset averages 210 FPS. Medium averages 172 FPS with a minimum of 146 FPS and a maximum of 198 FPS. High averages 141 FPS, and Ultra averages 88 FPS. The pattern mirrors 1080p but with lower absolute numbers due to the increased pixel count. The drop from High to Ultra is 53 FPS (37.6 percent), which is proportionally similar to 1080p. The Low to Medium gap is 38 FPS, and the Medium to High gap is 31 FPS, showing that each step up in quality carries a meaningful cost.

At 3840x2160, the Low preset averages 131 FPS. Medium averages 107 FPS with a minimum of 91 FPS and a maximum of 123 FPS. High averages 88 FPS, and Ultra averages 55 FPS. The Ultra preset at 4K is the most demanding configuration in the entire dataset, and the 55 FPS result is the lowest measured value. The gap between High and Ultra is 33 FPS (37.5 percent), consistent with the other resolutions. The Low to Medium gap is 24 FPS, and the Medium to High gap is 19 FPS. At 4K, even the Low preset fails to reach the 295 FPS seen at 1080p Low, highlighting the substantial cost of rendering four times the pixels.

The minimum and maximum frame rates are only provided for the Medium preset at each resolution. At 1080p Medium, the range is 205 to 277 FPS, a spread of 72 FPS. At 1440p Medium, the range is 146 to 198 FPS, a spread of 52 FPS. At 4K Medium, the range is 91 to 123 FPS, a spread of 32 FPS. The narrower spread at higher resolutions indicates that the frame time variance decreases as the GPU becomes more consistently loaded, which is a positive sign for stability in Downfall.

Resolution Scaling

The FPS data reveals how the combination scales across resolutions. Moving from 1080p to 1440p at the same settings incurs a consistent penalty. At Low settings, FPS drops from 295 to 210, a 28.8 percent reduction. At Medium, it drops from 241 to 172, a 28.6 percent reduction. At High, it drops from 198 to 141, a 28.8 percent reduction. At Ultra, it drops from 123 to 88, a 28.5 percent reduction. These nearly identical percentages indicate that the scaling from 1080p to 1440p is resolution-bound, with the GPU handling the extra pixels in a predictable linear fashion.

The scaling from 1440p to 4K is steeper. At Low settings, FPS drops from 210 to 131, a 37.6 percent reduction. At Medium, it drops from 172 to 107, a 37.8 percent reduction. At High, it drops from 141 to 88, a 37.6 percent reduction. At Ultra, it drops from 88 to 55, a 37.5 percent reduction. The jump from 1440p to 4K involves a 2.25x increase in pixel count, and the FPS penalty of roughly 37.5 percent aligns with the GPU becoming increasingly saturated. The consistency of these percentages across settings suggests that the limiting component remains the GPU throughout, as the CPU has enough headroom to feed it at all resolutions.

Comparing the full 1080p to 4K range, the total FPS reduction at Low settings is from 295 to 131, a 55.6 percent drop. At Medium, it is from 241 to 107, a 55.6 percent drop. At High, it is from 198 to 88, a 55.6 percent drop. At Ultra, it is from 123 to 55, a 55.3 percent drop. The uniformity of these drops—hovering around 55.5 percent—indicates that the scaling is almost entirely driven by pixel count rather than any other factor. This is characteristic of a GPU-bound scenario, where the CPU's performance does not change the scaling behavior.

The fact that the percentage drops are nearly identical across all settings further reinforces that the RX 9070 is the limiting component. If the CPU were the bottleneck at lower resolutions, we would expect the FPS at 1080p to plateau, making the percentage drop to 4K larger. Instead, the consistent scaling suggests that even at 1080p Low with 295 FPS, the GPU is still the primary constraint, and the Ryzen 9 9900X3D has ample capacity to keep up.

CPU Role

The AMD Ryzen 9 9900X3D is a 12-core, 24-thread processor based on the Zen 5 architecture, codenamed Granite Ridge. It operates on the AMD Socket AM5 platform with a base clock of 4.40 GHz and a boost clock of 5.50 GHz. The CPU has a 120 W TDP and supports DDR5 memory in a dual-channel configuration with a bandwidth of 89.6 GB/s. The cache hierarchy includes 80 KB of L1 per core, 1 MB of L2 per core, and a substantial 128 MB of L3 cache, which is a key feature of the X3D lineup.

In Downfall, the CPU's role is secondary to the GPU, as evidenced by the resolution scaling data. At 1080p Low, the combo achieves 295 FPS, which is high enough that a weaker CPU might struggle to maintain. However, the 9900X3D's strong single-thread performance ensures that the game's main thread is well-fed. The CPU scores 1269 in 3DMark single-thread tests and 6739 in Cinebench R23 single-core, which are strong results. The 3DMark 2-thread score of 2512 and 4-thread score of 4885 also indicate solid low-thread-count performance.

The multi-threaded capabilities are equally impressive, though less critical for Downfall. The Cinebench R23 multicore score is 47737, and the Geekbench multicore score is 22884. Passmark multithread results show a score of 56154. These numbers place the CPU in the 91st percentile, and the nearest rival data shows it trading blows with the Intel Core Ultra 5 245KF, which scores 55093. The 9900X3D's 128 MB of L3 cache is particularly beneficial in games that use large data sets, and while Downfall is a horror title rather than a simulation, the cache likely helps maintain consistent frame times.

The CPU's benchmark scores also include a Passmark physics score of 5340 and a Passmark single-thread score of 4646. The 3DMark 8-thread score is 9002, and the 16-thread score is 12490, with a max-thread score of 13795. These results show that the CPU scales well across thread counts, but for Downfall, the single-thread and low-thread performance are what matter most. The high boost clock of 5.50 GHz ensures that the game receives fast responses from the main thread, which is crucial for maintaining the high frame rates seen at lower resolutions.

The memory bandwidth of 89.6 GB/s is adequate for feeding the 12 cores, and the dual-channel DDR5 support is standard for this platform. The CPU's L3 cache of 128 MB is more than double that of many rivals, and while the measured FPS data does not isolate cache effects, the overall combo rank of 829 suggests that the CPU is not holding back the GPU. At 1080p Low, the 295 FPS result is likely near the maximum that this GPU can produce, meaning the CPU has sufficient headroom to avoid becoming a bottleneck. The consistent resolution scaling, with nearly identical percentage drops across all settings, confirms that the CPU is not limiting performance at any resolution tested.
