Downfall

The AMD Ryzen 9 5900X and NVIDIA GeForce RTX 4070 Ti pairing in Downfall produces a dataset that clearly separates CPU-bound and GPU-bound scenarios. The 5900X is a 12-core, 24-thread Zen 3 part with a base clock of 3.70 GHz and a boost clock of 4.80 GHz, running on the AMD Socket AM4 platform. Its 64 MB of L3 cache and dual-channel DDR4 memory support with 51.2 GB/s bandwidth provide substantial headroom for feeding a high-end graphics card. In synthetic benchmarks, the 5900X scores 33,150 in Cinebench R23 multi-core and 4,680 in single-core, placing it in the 90th percentile among all CPUs. Its nearest rivals include the AMD EPYC 4245P (0.2% ahead), the AMD Ryzen 7 PRO 8845HS (0.7% behind), the Intel Core i7-13700F (0.9% ahead), and the Intel Core i7-13700 (1% behind). The data shows that in Downfall, the CPU is rarely the limiting factor, except at the lowest resolution and settings where frame rates exceed 360 FPS.

CPU Role — cores, clocks, and how they relate to this game's results

The 5900X’s 12 cores and 24 threads are more than sufficient for Downfall, a horror title that does not appear to scale heavily with thread counts. The 3DMark benchmarks for the CPU illustrate a strong multi-threaded performance curve: 3,588 with 4 threads, 6,601 with 8 threads, and 10,075 at max threads. This indicates the processor can handle high thread counts without significant bottlenecks. However, the single-thread score of 941 and 2-thread score of 1,852 suggest that per-core performance is the more relevant metric for this game’s engine.

At 1080p with Low settings, the system achieves 364.4 FPS average. This is the highest frame rate in the entire dataset, and it is the point where the CPU’s boost clock of 4.80 GHz becomes critical. The data implies that at this setting, the GPU is not fully utilized, and the 5900X’s single-thread speed is the primary driver. The CPU’s PassMark single-thread score of 3,469 and Geekbench single-core score of 2,202 reinforce that this processor can sustain high instructions-per-clock, which is necessary for pushing frame rates past the 300 FPS mark.

The performance delta between 1080p Low (364.4 FPS) and 1080p Ultra (152.9 FPS) is 211.5 FPS, a drop of 58%. This dramatic reduction is not due to the CPU but rather to the increased graphical workload. The 5900X’s Cinebench R20 multi-core score of 13,923 shows it has ample computational headroom; the game’s engine, however, appears to be lightly threaded, making the CPU’s 12 cores almost secondary to its high boost clock. In the context of Downfall, the 5900X behaves like a high-frequency part rather than a multi-core workhorse, which is consistent with the minimal FPS differences between 4K High and 4K Medium.

GPU Role — VRAM, clocks, and how they relate to this game's results

The RTX 4070 Ti is the dominant component in this pairing, especially at higher resolutions and settings. It features 12 GB of GDDR6X memory on a 192-bit bus, yielding a bandwidth of 504.2 GB/s. The GPU’s base clock is 2310 MHz with a boost of 2610 MHz, and it packs 7,680 shading units, 240 TMUs, and 80 ROPs. Its FP32 performance of 40.09 TFLOPS and texture rate of 626.4 GTexel/s provide the raw throughput needed for Downfall's horror visuals.

The GPU’s 85th percentile ranking among all GPUs is reflected in its average benchmark score of 44,900. Its nearest rivals are the NVIDIA GeForce RTX 5090 Mobile (0.6% ahead), the Intel Arc A730M (1.5% ahead), the AMD Radeon Pro 580 (1.6% behind), and the AMD Radeon Pro 5500 XT (1.6% behind). Notably, the RTX 4070 Ti sits very close to these competitors in aggregate scores, but in Downfall, its 12 GB VRAM buffer appears sufficient even at 4K Ultra, where the average FPS drops to 70.0.

At 4K Ultra, the GPU is clearly the bottleneck. The jump from 4K High (109.9 FPS) to 4K Ultra (70.0 FPS) is a 39.9 FPS reduction, a 36% performance loss. This is a GPU-bound scenario, as the CPU’s role diminishes. The RTX 4070 Ti’s pixel rate of 208.8 GPixel/s is taxed heavily by the Ultra preset’s effects. The data shows that the 4070 Ti can handle 4K High with ease (109.9 FPS) but struggles to maintain 70 FPS at Ultra, indicating that the Ultra preset introduces computational demands that scale beyond the GPU’s 40.09 TFLOPS capability. The 12 GB VRAM does not appear to be a limiting factor, as the FPS drops are consistent with raw compute limitations rather than memory capacity issues.

Resolution Scaling — how FPS drops from 1080p to 4K and what it says about the limiting component

The measured FPS data across resolutions reveals a clear scaling pattern that identifies the limiting component at each step. Starting at 1080p Low, the system produces 364.4 FPS. Moving to 1440p Low reduces this to 260.7 FPS, a drop of 103.7 FPS (28%). Going further to 4K Low yields 162.3 FPS, another 98.4 FPS drop (38%). These reductions are larger than what pure GPU scaling would suggest, indicating that the CPU is still partially involved at Low settings, but the GPU is increasingly stressed as pixel count rises.

For High settings, the scaling is more linear: 1080p High at 246.1 FPS, 1440p High at 177.0 FPS, and 4K High at 109.9 FPS. The drop from 1080p to 1440p is 69.1 FPS (28%), and from 1440p to 4K is 67.1 FPS (38%). This consistency suggests that at High settings, the system is balanced, with neither component fully saturated. The 5900X’s 3DMark 8-thread score of 6,601 and the GPU’s 3DMark Steel Nomad DX12 score of 5,024 both contribute to this equilibrium.

The most telling scaling occurs at Ultra settings: 1080p Ultra at 152.9 FPS, 1440p Ultra at 110.3 FPS, and 4K Ultra at 70.0 FPS. The drop from 1080p to 1440p is 42.6 FPS (28%), but the drop from 1440p to 4K is 40.3 FPS (37%). The absolute FPS values at 4K Ultra (70.0) are less than half of those at 1080p Ultra (152.9), demonstrating that the GPU is the primary bottleneck at 4K. The CPU’s role becomes negligible, as the 5900X’s PassMark multi-thread score of 39,002 and Cinebench R23 multi-core score of 33,150 are unused at this level. The data indicates that Downfall is GPU-bound at 4K, CPU-bound at 1080p Low, and balanced in between.

Measured FPS Breakdown — resolution by resolution, settings by settings, exact numbers

The dataset provides 12 measured FPS points, covering three resolutions and four settings each. At 1920x1080, the system delivers 364.4 FPS on Low, 302.7 FPS on Medium, 246.1 FPS on High, and 152.9 FPS on Ultra. The gap between Low and Ultra is 211.5 FPS, with the largest single-step drop occurring between High and Ultra (93.2 FPS). This suggests that the Ultra preset adds significant shading and post-processing effects that disproportionately tax the GPU.

At 2560x1440, the scores are 260.7 FPS on Low, 213.3 FPS on Medium, 177.0 FPS on High, and 110.3 FPS on Ultra. The step from Medium to High (36.3 FPS) is smaller than the step from High to Ultra (66.7 FPS), again highlighting Ultra as a major performance hurdle. The 1440p data shows a more gradual decline, with each preset tier costing roughly 20-30% performance, except for the final Ultra step which costs 38%.

At 3840x2160, the results are 162.3 FPS on Low, 130.4 FPS on Medium, 109.9 FPS on High, and 70.0 FPS on Ultra. The drop from Low to Medium is 31.9 FPS, from Medium to High is 20.5 FPS, and from High to Ultra is 39.9 FPS. The 4K Ultra score of 70.0 FPS is the only sub-100 FPS result in the entire dataset, indicating that this configuration is at the edge of playability for the most demanding preset. The data shows a consistent pattern: Ultra settings cost approximately 35-40% performance over High at every resolution, while Medium typically offers a 15-20% improvement over High.

Settings Recommendations

Based on the measured FPS data, the optimal experience depends on the target resolution and desired frame rate. For 1920x1080, the Medium preset delivers 302.7 FPS, which is more than sufficient for any display, and it is only 61.7 FPS slower than Low. The High preset at 246.1 FPS offers a better visual quality per frame cost, but the jump to Ultra (152.9 FPS) is not worth the 93.2 FPS loss. For 1080p, Medium or High provides the best balance, with High being the recommended choice for users with 144Hz or 165Hz monitors.

At 2560x1440, the High preset at 177.0 FPS is the sweet spot, as it remains above the 144Hz refresh rate threshold while offering better visuals than Medium (213.3 FPS). The Ultra preset at 110.3 FPS is playable but sacrifices 66.7 FPS compared to High, which may not be justified for the visual upgrade. For 1440p, High is the clear recommendation, as it maintains high frame rates without the steep performance penalty of Ultra.

For 3840x2160, the situation is more constrained. The High preset at 109.9 FPS is the highest quality setting that remains above 100 FPS, making it the recommended choice for 4K gaming. The Ultra preset at 70.0 FPS is below the 100 FPS threshold and may introduce noticeable stutter on high-refresh displays. The Medium preset at 130.4 FPS offers a significant frame rate advantage over High (20.5 FPS more) but with reduced visual fidelity. For 4K, High is the best overall experience, as it balances the GPU’s 40.09 TFLOPS capability with the game’s demands, ensuring smooth gameplay without dropping to the sub-100 FPS territory of Ultra.
