Downfall

The AMD Ryzen 9 9900X and AMD Radeon RX 7900 XT combination delivers a remarkably fluid experience in Downfall across all tested resolutions, but the choice of graphics preset dramatically shapes the outcome. At 1920x1080, the High preset produces an average of 224.7 FPS, which sits comfortably above the 144Hz refresh rate most gamers target, while the Medium preset reaches 274.2 FPS. However, the Ultra preset drops to 139.3 FPS, which is still playable but represents a significant 38% reduction from High. The data suggests that High is the optimal preset at 1080p, as it maintains high frame rates without the performance penalty of Ultra.

Moving to 2560x1440, the High preset yields 159.1 FPS, which is excellent for high-refresh-rate monitors. The Medium preset reaches 196.6 FPS, offering even more headroom, while Low hits 242.9 FPS for competitive play. The Ultra preset at this resolution falls to 102.9 FPS, which is still above 60 FPS but begins to strain the GPU. At 3840x2160, the situation changes notably: High produces 97.5 FPS, Medium delivers 119.5 FPS, and Low reaches 151.8 FPS, while Ultra drops to 65.2 FPS. For 4K gaming, the Medium preset appears to be the sweet spot, offering a 22.6% improvement over High while maintaining a frame rate well above the 60 FPS threshold.

The Low preset consistently delivers the highest frame rates across all resolutions, with 336.7 FPS at 1080p, 242.9 FPS at 1440p, and 151.8 FPS at 4K. This makes it the best choice for extreme refresh rate displays or esports scenarios, though the visual fidelity trade-off may not be worth it for a horror title where atmosphere matters. Overall, the benchmark data indicates that High at 1080p or 1440p, or Medium at 4K, provides the best balance of visual quality and performance for this hardware combination.

GPU Role

The AMD Radeon RX 7900 XT serves as the primary performance driver in this combination, and its memory configuration plays a critical role in Downfall’s results. The GPU features 20 GB of GDDR6 memory on a 320-bit bus, delivering 800.0 GB/s of bandwidth. This substantial memory pool ensures that even at 3840x2160 with Ultra settings, where the frame rate drops to 65.2 FPS, texture streaming and asset loading remain fluid. The memory clock runs at 2500 MHz, translating to 20 Gbps effective, which is sufficient to feed the 5376 shading units without bottlenecking.

The GPU’s clock behavior is equally important. The base clock is 1387 MHz, but the boost clock reaches 2394 MHz, with a game clock of 2025 MHz. This dynamic range allows the card to scale performance based on thermal and power headroom. In Downfall, the frame rate scaling from Low to Ultra at 4K—from 151.8 FPS down to 65.2 FPS—shows a 57% performance drop, indicating that the GPU is the limiting factor at higher settings. The RDNA 3.0 architecture, built on a 5 nm process with 57,700 million transistors, provides the compute power needed for the horror game’s lighting and shadow effects, with the FP32 throughput reaching 51.48 TFLOPS.

The GPU’s 84 ray tracing cores are present, though Downfall does not appear to stress them heavily based on the moderate frame rate differences between presets. The pixel rate of 459.6 GPixel/s and texture rate of 804.4 GTexel/s suggest the card excels at fill-rate-bound scenes, which is typical for horror environments with dense geometry. The 192 ROPs handle the final output stage, and at 1080p Ultra, the card still manages 139.3 FPS, demonstrating that even the most demanding settings remain playable. With a TDP of 300 W and a suggested PSU of 700 W, the card draws significant power, but the performance per frame justifies the requirement. The GPU’s percentile rank of 82 against all GPUs places it in the upper tier, and its average benchmark score of 38358 aligns closely with its nearest rivals: the NVIDIA GeForce RTX 5080 Mobile (deltaPct 0), NVIDIA CMP 70HX (deltaPct 0.3), NVIDIA GeForce MX570 (deltaPct -0.4), and NVIDIA GeForce RTX 4080 Mobile (deltaPct 0.6). This tight clustering indicates the RX 7900 XT is competitively positioned in raw compute terms, even if Downfall’s results show its strengths in memory bandwidth and fill rate.

How This Combo Ranks

The AMD Ryzen 9 9900X and AMD Radeon RX 7900 XT combination ranks 368th out of 1741 tested combos in Downfall, placing it in the top 21% of all configurations. This ranking reflects the strong synergy between the 12-core, 24-thread CPU and the high-end GPU, though it is not at the very top of the leaderboard. The rank position suggests that there are 367 combinations that deliver higher average frame rates, likely featuring more powerful GPUs or newer architectures, but the 368th spot out of 1741 is still a solid showing for this pairing.

The ranking is influenced by the GPU’s performance characteristics, as Downfall is a visually demanding title that scales heavily with graphics hardware. The RX 7900 XT’s percentile rank of 82 against all GPUs indicates it is in the upper echelon, but it is not the absolute fastest. The combo’s rank of 368 in a field of 1741 means it outperforms roughly 79% of tested combinations, which is a strong result for a system targeting high-refresh-rate gaming at 1440p or solid 4K performance. The CPU’s percentile rank of 94 against all CPUs is higher than the GPU’s, suggesting that the processor is not the limiting factor in most scenarios.

The data shows that the combo’s performance is well-balanced, with the GPU handling the bulk of the rendering workload while the CPU provides enough headroom to avoid bottlenecks at lower resolutions. At 1080p Low, the 336.7 FPS result demonstrates that the CPU can feed the GPU efficiently, while at 4K Ultra, the 65.2 FPS output indicates the GPU is the primary constraint. This balance is reflected in the combo’s rank, which places it in the upper quartile of all tested systems. For users with high-refresh-rate 1440p monitors, this combination is well-suited, as it delivers 159.1 FPS on High settings, a figure that ranks favorably against the broader field.

CPU Role

The AMD Ryzen 9 9900X provides the computational backbone for this combination, and its 12 cores and 24 threads are more than sufficient for Downfall’s demands. Built on the Zen 5 architecture with the Granite Ridge codename, this processor operates on a 4 nm process from TSMC, with a base clock of 4.40 GHz and a boost clock of 5.60 GHz. The 64 MB of shared L3 cache, combined with 1 MB of L2 cache per core and 80 KB of L1 cache per core, ensures that game logic and physics calculations have fast access to data. The CPU’s TDP of 120 W is modest for a 12-core part, and it supports DDR5 memory with a dual-channel configuration, delivering 89.6 GB/s of bandwidth.

In Downfall, the CPU’s role is less about raw frame rate and more about maintaining consistency. The benchmark data shows that at 1080p Low, the combo reaches 336.7 FPS, which taxes the CPU heavily, but the 24 threads handle the game’s processing without issue. The CPU’s single-thread performance is strong, with a 3DMark single-thread score of 1286 and a Cinebench R23 single-core score of 6555, which helps in scenarios where the game’s main thread is the bottleneck. The multi-threaded performance is equally impressive, with a Cinebench R23 multicore score of 46438 and a Geekbench multicore score of 19827, ensuring that background tasks and game threads do not interfere.

The CPU’s average benchmark score of 54450 places it in the 94th percentile of all CPUs, and its nearest rivals show tight competition. The AMD Ryzen 9 9900X3D scores 54681, just 0.4% higher, while the Intel Core i7-14700F scores 54097, 0.7% lower. The Intel Core Ultra 5 245K and 245KF score 55304 and 55421, respectively, putting them 1.5% and 1.8% ahead. This clustering indicates that the 9900X is competitively positioned, though not the absolute fastest in its class. In Downfall, the CPU’s performance is more than adequate, as evidenced by the fact that frame rates scale consistently with GPU settings changes, with no evidence of CPU-induced stuttering or frame drops. The processor’s PCIe Gen 5 support with 24 lanes provides ample bandwidth for the GPU, and its unlocked multiplier allows for overclocking, though the stock performance is already sufficient for this title.
