Downfall

# How This Combo Ranks

The AMD Ryzen 9 9900X paired with the AMD Radeon RX 7800 XT lands at rank 1234 out of 3716 tested combinations in Downfall. This places the combo in the upper third of all tested systems, a solid position for a horror title that tends to favor GPU throughput over CPU-bound scenarios. The rank reflects a balanced pairing—neither component is dramatically holding back the other in this game, though the data reveals where the bottlenecks form at different settings and resolutions.

In percentile terms, the CPU sits at the 92nd percentile among all processors, while the GPU ranks at the 51st percentile among all graphics cards. That discrepancy is telling: the processor is a top-tier part, but the graphics card is more mid-pack in the broader GPU landscape. In Downfall specifically, the combo's overall ranking suggests the GPU is the limiting factor in most configurations, a conclusion reinforced by the measured frame rates across the resolution spectrum.

GPU Role

The Radeon RX 7800 XT brings 16 GB of GDDR6 memory on a 256-bit bus, with a memory bandwidth of 624.1 GB/s. Its boost clock reaches 2430 MHz, with a game clock of 2124 MHz and a base clock of 1295 MHz. The card is built on the RDNA 3.0 architecture with 3840 shading units, 240 texture mapping units, and 96 raster operation units, along with 60 ray tracing cores. These specifications translate into a pixel rate of 233.3 GPixel/s and a texture rate of 583.2 GTexel/s, with FP32 performance rated at 37.32 TFLOPS.

In Downfall, the GPU's memory capacity is more than sufficient—16 GB is ample for the game's texture demands at any of the tested settings. The measured frame rates show that the card is capable of delivering playable performance even at 4K Ultra, albeit with a significant drop from lower presets. The GPU's average benchmark score of 11627 places it at the 51st percentile, and its nearest rivals include the NVIDIA GeForce GTX 1660 (with a delta of -0.5%) and the AMD Radeon RX 6500 XT (with a delta of -1.8%). These comparisons underscore that the RX 7800 XT is a mid-range performer in the overall GPU hierarchy, yet in Downfall it manages to hold its own due to the game's optimization.

Resolution Scaling

The data shows a clear and consistent pattern: frame rates decrease as resolution increases, but the rate of decline is not uniform across settings. At 1080p Low, the combo delivers 282 FPS average; at 1440p Low, that drops to 202 FPS (a 28% reduction); and at 4K Low, it falls to 125 FPS (a further 38% reduction from 1440p). This steep decline from 1440p to 4K indicates that the GPU is becoming the primary limiting factor at higher resolutions, as the CPU has ample headroom to feed frames at 1080p.

The scaling pattern is similar for High settings: 189 FPS at 1080p, 135 FPS at 1440p, and 84 FPS at 4K. The percentage drops are 29% and 38% respectively, mirroring the Low preset's behavior. At Medium settings, the frame rates are 231 FPS at 1080p, 165 FPS at 1440p, and 103 FPS at 4K, with corresponding drops of 29% and 38%. The Ultra preset shows the most dramatic scaling: 118 FPS at 1080p, 85 FPS at 1440p (a 28% drop), and 53 FPS at 4K (a 38% drop from 1440p). This consistent pattern across all settings suggests that the GPU's rendering workload scales predictably with pixel count, and the CPU is not introducing a bottleneck at any resolution.

Measured FPS Breakdown

At 1920x1080, the combo delivers its highest frame rates across all presets. The Low preset averages 282 FPS, Medium averages 231 FPS with a minimum of 196 FPS and a maximum of 266 FPS, High averages 189 FPS, and Ultra averages 118 FPS. These numbers indicate that at 1080p, the system is largely CPU-bound or at least has enough GPU headroom to push very high frame rates. The jump from 118 FPS at Ultra to 189 FPS at High is a 60% improvement, while dropping from High to Medium yields another 22% gain, and from Medium to Low another 22% gain.

Moving to 2560x1440, the frame rates remain strong but begin to show the GPU's limits. Low averages 202 FPS, Medium averages 165 FPS with a minimum of 140 FPS and a maximum of 190 FPS, High averages 135 FPS, and Ultra averages 85 FPS. The gap between High and Ultra is 50 FPS, or a 37% difference, which is more pronounced than the 60 FPS gap (34%) seen at 1080p. At 1440p, the system is transitioning from CPU-bound to GPU-bound behavior, particularly at Ultra settings where the 85 FPS average is approaching the threshold where GPU load becomes dominant.

At 3840x2160, the GPU is clearly the limiting factor. Low averages 125 FPS, Medium averages 103 FPS with a minimum of 87 FPS and a maximum of 118 FPS, High averages 84 FPS, and Ultra averages 53 FPS. The Ultra preset at 4K is the only configuration that drops below 60 FPS, making it borderline for smooth gameplay. The progression from Low to Medium at 4K is a 22 FPS or 18% reduction, from Medium to High is a 19 FPS or 18% reduction, and from High to Ultra is a 31 FPS or 37% reduction. This last drop is the steepest single-step penalty in the entire dataset, highlighting the disproportionate cost of Ultra settings at 4K.

CPU Role

The AMD Ryzen 9 9900X is a 12-core, 24-thread processor based on the Zen 5 architecture (Granite Ridge), manufactured on a 4 nm process by TSMC. It has a base clock of 4.40 GHz and a boost clock of 5.60 GHz, with a TDP of 120 W. The cache hierarchy includes 80 KB of L1 per core, 1 MB of L2 per core, and 64 MB of L3 cache. Memory support is DDR5 with dual-channel configuration and a bandwidth of 89.6 GB/s. The CPU's benchmark results are strong: a Cinebench R23 multi-core score of 32172 and single-core score of 2253, a Geekbench multi-core score of 22174 and single-core score of 3010, and a PassMark multi-thread score of 54643.

In Downfall, the CPU's role is primarily to feed the GPU with draw calls and game logic. The measured frame rates at 1080p Low (282 FPS) and 1440p Low (202 FPS) suggest that the CPU is not a bottleneck at these settings, as the frame rates are well above what the GPU can render at higher resolutions. The CPU's single-thread performance, as indicated by the 3DMark single-thread score of 1286 and PassMark single-thread score of 4672, is more than adequate for a game like Downfall, which is a horror title from 2016 and likely not heavily multithreaded. The CPU's percentile rank of 92 among all processors, and its nearest rivals (the AMD EPYC 9015 with a delta of -0.1%, the Intel Core i9-14900 with a delta of -1.1%, and the Intel Xeon Platinum 8260M with a delta of -1.4%), confirm that this is a top-tier processor that will not limit performance in this game.

Settings Recommendations

Based on the measured frame rates, the optimal experience depends on the target resolution and the user's preference for frame rate versus visual fidelity. At 1080p, the High preset at 189 FPS average offers a strong balance—well above the 144 Hz refresh rate common on modern monitors, with better visual quality than Medium or Low. The Ultra preset at 118 FPS is still playable but may not be worth the 38% frame rate penalty over High for the marginal visual gains in a horror game where atmosphere matters more than fine detail.

At 1440p, the High preset at 135 FPS is the sweet spot, providing smooth gameplay on 120 Hz or 144 Hz displays while maintaining good visual quality. The Medium preset at 165 FPS is also viable for users who prioritize frame rate, but the jump from Medium to High costs 30 FPS (18%) while delivering noticeably better textures and effects. The Ultra preset at 85 FPS is playable on 60 Hz displays but may feel less responsive on high-refresh monitors.

At 4K, the situation is more constrained. The High preset at 84 FPS is the best option for players who want both resolution and decent frame rates, as it stays above 60 FPS. The Medium preset at 103 FPS offers more headroom for smoother motion, but the visual downgrade from High is noticeable. The Ultra preset at 53 FPS is not recommended for most users, as it dips below the 60 FPS threshold and the 37% drop from High is substantial. The Low preset at 125 FPS is only advisable for competitive play where frame rate trumps visuals, though the game's horror genre typically benefits from higher graphical fidelity.
