Downfall

The AMD Ryzen 9 5900X paired with the NVIDIA GeForce RTX 5090 delivers exceptionally high frame rates in Downfall, a 2016 horror title. The data shows this combination is capable of maintaining fluid performance across all tested resolutions, with the most demanding Ultra preset still producing playable results at 4K. This analysis breaks down the measured performance, the role of each component, and how this specific pairing ranks against other tested configurations.

Settings Recommendations

For this specific CPU and GPU pairing, the benchmark data indicates that the High preset offers the most balanced experience across all resolutions. At 3840x2160, the High preset achieves an average of 135 FPS, which is a substantial 51 FPS improvement over the Ultra preset's 84 FPS average. This performance gain comes with a visual trade-off that is often imperceptible in a fast-paced horror environment, making High the optimal choice for 4K gaming.

At 2560x1440, the High preset delivers an average of 217 FPS, which is more than sufficient for high-refresh-rate monitors. The Medium preset at this resolution produces 264 FPS average, but the jump from Medium to High represents only a 47 FPS drop while typically providing noticeably better image quality. The Ultra preset at 1440p yields 135 FPS, which is still smooth but represents a significant 82 FPS reduction compared to High.

The 1920x1080 resolution results show that this combination is heavily GPU-bound at lower settings, with the Low preset hitting 387 FPS average. However, the High preset at 303 FPS is the recommended choice here, as it provides a 116 FPS advantage over Ultra while maintaining frame rates that exceed the refresh rate capabilities of virtually all monitors. The Medium preset at 361 FPS sits between these two, but the High preset's balance of visual fidelity and performance makes it the standout option.

The data consistently shows that the Ultra preset creates a bottleneck, reducing frame rates by roughly 37% to 45% compared to High across all resolutions. Given that the High preset maintains frame rates well above 135 FPS even at 4K, there is no scenario in the measured data where Ultra's additional visual effects justify the significant performance cost.

GPU Role

The NVIDIA GeForce RTX 5090 is the dominant performance driver in this pairing. Its 32 GB of GDDR7 memory on a 512-bit bus provides a bandwidth of 1.79 TB/s, which is more than sufficient for Downfall's textures and assets at any resolution. The GPU's memory configuration ensures that VRAM capacity is never a limiting factor in the measured results.

The GPU's clock speeds are substantial, with a base clock of 2017 MHz and a boost clock of 2407 MHz. These clocks, combined with the Blackwell 2.0 architecture and 21,760 shading units, allow the RTX 5090 to process the game's geometry and lighting effects with minimal latency. The GPU also features 170 ray tracing cores and 680 tensor cores, though Downfall's 2016 release date means it likely does not utilize these modern features extensively.

The RTX 5090's raw compute capabilities are reflected in its benchmark scores, including a 3DMark Steel Nomad DX12 score of 18,355 and a Passmark G3D score of 39,650. Its average benchmark score of 79,842 places it in the 92nd percentile of all GPUs, showing that it is one of the most powerful graphics cards in the database. The measured FPS data confirms this, as the GPU alone is capable of pushing frame rates beyond 300 FPS at 1080p on High settings.

The GPU's performance scaling across resolutions is linear and predictable. At High settings, the RTX 5090 delivers 303 FPS at 1080p, 217 FPS at 1440p, and 135 FPS at 4K. This scaling pattern indicates that the GPU is the primary bottleneck at lower resolutions, while at 4K, the workload becomes more balanced between the GPU and CPU.

CPU Role

The AMD Ryzen 9 5900X provides the computational foundation for this pairing. With 12 cores and 24 threads based on the Zen 3 architecture, this CPU offers substantial multi-threaded performance that prevents it from becoming a bottleneck in most gaming scenarios. Its base clock of 3.70 GHz and boost clock of 4.80 GHz provide strong single-thread performance, which is critical for game logic and physics calculations.

The CPU's benchmark results demonstrate its capability. In Cinebench R23, it scores 16,262 in multi-core and 1,527 in single-core tests. The Geekbench scores of 14,118 multi-core and 2,083 single-core further validate its performance. The 3DMark 16-thread score of 9,075 shows that the CPU can handle substantial parallel workloads, while the single-thread score of 941 indicates solid per-core performance.

In Downfall, the CPU's role becomes more apparent at lower resolutions and settings. At 1080p Low settings, the combination achieves 387 FPS average, a figure that approaches the practical limits of the CPU's single-thread capabilities. The data shows that the CPU is able to keep up with the RTX 5090's massive frame generation, but the performance gap between 1080p Low (387 FPS) and 1080p High (303 FPS) suggests that the GPU is still the primary bottleneck even at lower settings.

The Ryzen 9 5900X's 64 MB of L3 cache and dual-channel DDR4 memory support with 51.2 GB/s bandwidth provide adequate data throughput for the game's asset streaming. The CPU's 105W TDP and 7nm process node from TSMC indicate efficient power delivery, which helps maintain consistent clock speeds during extended gaming sessions. Its average benchmark score of 41,376 places it in the 87th percentile of all CPUs, showing that it remains a capable processor for this workload.

How This Combo Ranks

The AMD Ryzen 9 5900X + NVIDIA GeForce RTX 5090 combination ranks 128th out of 3,716 tested combos in Downfall. This places it in the top 3.4% of all configurations tested, indicating that this pairing delivers near-elite performance for this title. The high rank is primarily attributable to the RTX 5090's exceptional rasterization performance, as the CPU's percentile ranking is lower than the GPU's.

The data shows that the combo's rank is likely constrained by the CPU's performance ceiling. The Ryzen 9 5900X's nearest rivals include the Intel Core Ultra 7 366H (0.3% higher average score), Intel Core Ultra 7 356H (0.4% higher), and AMD Ryzen AI 5 PRO 440 (0.4% higher), all of which have comparable average benchmark scores. The Intel Core i7-14650HX is 0.5% lower in score, showing that the CPU is competitively positioned within its performance class.

The RTX 5090's nearest rivals in the GPU database include the NVIDIA Tesla P100 PCIe 16 GB (0.3% higher score), NVIDIA Tesla P100 PCIe 12 GB (0.6% higher), and AMD Radeon RX 6850M XT (1.1% higher), with the AMD Radeon Pro Vega 64X being 1.4% lower. These deltas are minimal, indicating that the GPU is among the fastest in the database, but the combo's 128th rank suggests that other top-tier GPU pairings with faster CPUs achieve better results in Downfall.

Given that the combo achieves 135 FPS at 4K High settings, the rank of 128 is expected, as many configurations with the RTX 5090 paired with newer, higher-clocked CPUs would likely produce higher frame rates in CPU-limited scenarios. However, for a 2020-era CPU paired with a 2025 GPU, this rank demonstrates that the combination is well-balanced for this particular game.
