Downfall

How This Combo Ranks

The AMD Ryzen 9 9900X3D paired with the AMD Radeon RX 7800 XT lands at rank 916 out of 2928 tested combos in Downfall. That places this configuration in the top third of all systems tested, a solid result for a horror title that tends to favor strong single-thread performance and adequate GPU throughput. The rank reflects the balance between the two components: the CPU is a top-tier part while the GPU is more mid-range in the grand scheme of the database, and the combination produces a system that handles Downfall comfortably at most settings.

Benchmark percentile data reinforces this interpretation. The Ryzen 9 9900X3D sits in the 91st percentile among all CPUs, meaning it outperforms the vast majority of processors in the database. The RX 7800 XT, by contrast, sits in the 51st percentile among all GPUs, a more middling placement. This disparity is the defining characteristic of this combo: the processor is clearly the stronger component, and the GPU is likely the limiting factor in most scenarios, especially at higher resolutions.

The CPU's nearest rivals in the database illustrate its standing. The Intel Core Ultra 5 245KF scores just 0.6% higher on average, while the Intel Core Ultra 5 245K trails by 1.3%. The Intel Xeon 6505P is 2% behind, and the Intel Core i7-14700F is 2.1% behind. These are narrow margins, indicating that the 9900X3D is competitive with but not dramatically ahead of other high-end desktop processors in general benchmark averages. For Downfall specifically, the combo ranking suggests the game rewards the CPU's capabilities, though the GPU's percentile placement tempers the overall result.

Resolution Scaling

The frame rate scaling from 1080p to 4K reveals a system that is increasingly GPU-bound at higher resolutions. At Low settings, the combo delivers 282 FPS at 1920x1080, drops to 202 FPS at 2560x1440, and falls to 125 FPS at 3840x2160. That represents a 55.7% drop from 1080p to 4K, a substantial decrease that points to the GPU struggling to keep up with the pixel count.

At High settings, the pattern is similar but slightly less severe. The system produces 189 FPS at 1080p, 135 FPS at 1440p, and 84 FPS at 4K. The drop from 1080p to 4K here is 55.6%, nearly identical to the Low settings scaling. This consistency suggests that the RX 7800 XT's 16 GB of memory and 256-bit bus are sufficient for the game's data requirements, but the raw compute throughput becomes the bottleneck as resolution climbs.

Ultra settings tell a more dramatic story. At 1080p, the combo manages 118 FPS; at 1440p, it drops to 85 FPS; and at 4K, it falls to 53 FPS. The 1080p to 4K drop is 55.1%, again consistent with the other settings. However, the absolute numbers at 4K Ultra are low enough to suggest that players seeking maximum visual fidelity at 4K would need a more powerful GPU.

The limiting component is clear from this scaling behavior. The CPU's high percentile ranking and strong benchmark scores, including a Cinebench R23 multicore score of 47737 and a Geekbench single-core score of 3041, indicate that it is not the constraint here. The GPU's 51st percentile placement and the consistent FPS drops across resolutions point to the RX 7800 XT as the component holding back performance at higher resolutions. At 1080p, the CPU can feed the GPU effectively; at 4K, the GPU simply cannot render frames fast enough.

Measured FPS Breakdown

At 1920x1080, the combo delivers its highest frame rates. Low settings produce an average of 282 FPS, which is exceptionally high for a horror game and indicates that the system is nowhere near its limits at this resolution. Medium settings yield 231 FPS with a minimum of 196 and a maximum of 266, showing smooth frame pacing. High settings drop to 189 FPS, still well above the threshold for high-refresh-rate monitors. Ultra settings bring the average down to 118 FPS, which remains playable but represents a significant step down from the lower settings.

At 2560x1440, the system continues to perform strongly. Low settings produce 202 FPS, a 28.4% drop from 1080p. Medium settings deliver 165 FPS with a minimum of 140 and a maximum of 190, indicating that the game remains fluid even during demanding scenes. High settings show 135 FPS, which is comfortably playable. Ultra settings drop to 85 FPS, which is still acceptable for most players but shows the GPU beginning to strain.

At 3840x2160, the frame rates reflect the GPU's limitations. Low settings produce 125 FPS, which is respectable for 4K. Medium settings deliver 103 FPS with a minimum of 87 and a maximum of 118, showing that the game remains smooth at this resolution with moderate settings. High settings drop to 84 FPS, which is borderline for 4K gaming. Ultra settings fall to 53 FPS, which is playable but not ideal for a smooth experience. The minimum frame rate data is only available for Medium settings at each resolution, and the 87 FPS minimum at 4K Medium suggests that the system can maintain playable frame rates even in the worst-case scenarios captured.

The Ultra settings at 4K show the largest gap between the combo's capability and the game's demands. The jump from High to Ultra at 4K is a 36.9% drop in average FPS, from 84 to 53. This indicates that Ultra settings introduce significant additional rendering load, likely from increased shadow quality, texture detail, and post-processing effects that tax the GPU's 37.32 TFLOPS of FP32 compute.

GPU Role

The AMD Radeon RX 7800 XT is the component that determines this combo's frame rates in Downfall, particularly at higher resolutions. The GPU features 16 GB of GDDR6 memory on a 256-bit bus, providing 624.1 GB/s of memory bandwidth. This memory configuration is sufficient for the game's texture and geometry data, as evidenced by the consistent frame rate scaling across settings.

The GPU's clock speeds are notable: a base clock of 1295 MHz, a game clock of 2124 MHz, and a boost clock of 2430 MHz. The boost clock represents a significant headroom over the base clock, allowing the GPU to increase performance when thermal and power conditions permit. This boost behavior likely contributes to the frame rates observed at 1080p and 1440p, where the GPU can operate at higher clocks without hitting power limits.

The GPU's compute capabilities are defined by its 3840 shading units, 240 texture mapping units, and 96 render output units. The 60 ray tracing cores support DirectX 12 Ultimate, though Downfall's horror genre may not heavily utilize ray tracing. The GPU's 37.32 TFLOPS of FP32 performance and 583.2 GTexel/s texture rate provide the raw throughput needed for the game's rendering workload.

The RX 7800 XT's benchmark scores place it in the 51st percentile among all GPUs, with an average score of 11627. Its nearest rival is the NVIDIA GeForce GTX 1660, which scores 0.5% higher, and the AMD Radeon RX 6500 XT, which scores 1.8% higher. This tight clustering suggests that the RX 7800 XT is performance-competitive with a range of other GPUs in general benchmarks, though its 16 GB memory capacity and modern architecture should give it an edge in memory-intensive scenarios.

The GPU's role in Downfall is most evident at 4K Ultra, where the 53 FPS average represents the system's weakest performance. The 16 GB memory buffer is not the constraint here; rather, the GPU's compute throughput and memory bandwidth are insufficient to maintain higher frame rates at maximum settings. At 1080p, the GPU is not the primary bottleneck, as evidenced by the 282 FPS Low setting result, which suggests that the CPU and game engine are more limiting at lower resolutions.

CPU Role

The AMD Ryzen 9 9900X3D is the standout component in this combo, and its capabilities help ensure that the system never becomes CPU-bound in Downfall. The processor features 12 cores and 24 threads, operating at a base clock of 4.40 GHz and a boost clock of 5.50 GHz. This high boost clock is critical for a game like Downfall, which likely benefits from strong single-thread performance in its core gameplay loop.

The CPU's architecture is Zen 5, built on a 4 nm process at TSMC with 16,630 million transistors across a dual-die design. The 128 MB of L3 cache is a defining feature of the X3D series, providing a large cache pool that can reduce memory latency and improve performance in cache-sensitive workloads. The CPU supports DDR5 memory with a dual-channel bus and 89.6 GB/s of memory bandwidth, which is sufficient for feeding the GPU without creating a memory bottleneck.

Benchmark results confirm the CPU's strength. The Cinebench R23 multicore score of 47737 and single-core score of 6739 indicate excellent performance across both multi-threaded and single-threaded workloads. The Geekbench scores of 22884 (multicore) and 3041 (single-core) reinforce this picture. The PassMark multithread score of 56154 and floating-point math score of 119622 show strong computational throughput.

The CPU's 91st percentile ranking among all CPUs places it well above the GPU's 51st percentile. In Downfall, this means the CPU can consistently deliver frames to the GPU without becoming a limiting factor. At 1080p Low, the 282 FPS result suggests that the CPU is capable of driving frame rates far beyond what the GPU can render at higher settings.

The nearest CPU rivals show that the 9900X3D is competitive with other high-end processors, but not dominant. The Intel Core Ultra 5 245KF is 0.6% faster on average, while the Intel Core Ultra 5 245K is 1.3% slower. These small deltas indicate that the CPU's advantage over its peers is marginal in general benchmarks, though its specific combination of high clock speeds and large cache may provide a more significant advantage in Downfall's specific workload.

The CPU's role is most apparent in the frame rate consistency across settings. The minimum FPS values measured at Medium settings (196 at 1080p, 140 at 1440p, and 87 at 4K) show that the system maintains smooth frame delivery even in demanding scenes. This consistency is likely attributable to the CPU's ability to handle game logic and draw calls without stuttering, allowing the GPU to work at its full potential.
