Downfall

# Downfall with AMD Ryzen 7 7800X3D + NVIDIA GeForce RTX 5090 D

The AMD Ryzen 7 7800X3D paired with the NVIDIA GeForce RTX 5090 D delivers exceptional frame rates in Downfall, a 2016 horror title that remains demanding at high resolutions. This combination ranks 27th out of 2,928 tested combos, placing it in the top 1% of all configurations. The data shows a system capable of maintaining triple-digit frame rates at 4K with High settings, while 1080p Low reaches 420 FPS, suggesting the CPU becomes a meaningful constraint only at the lowest resolutions and settings. The benchmark results paint a picture of a high-end pairing where the GPU dominates at higher resolutions, but the CPU's 8-core/16-thread design with 96 MB of L3 cache keeps pace admirably across the entire settings spectrum.

Resolution Scaling

The FPS progression from 1080p to 4K reveals how the workload shifts between components. At 1080p High, the system produces 324 FPS, which drops to 231 FPS at 1440p High (a 28.7% reduction) and further to 144 FPS at 4K High (a 55.6% reduction from 1080p). This scaling pattern indicates that the GPU becomes progressively more dominant as resolution increases, while the CPU has ample headroom at lower resolutions.

The Low settings tier shows even more dramatic scaling. At 1080p Low, the system reaches 420 FPS, dropping to 345 FPS at 1440p Low (a 17.9% reduction) and 214 FPS at 4K Low (a 49.0% reduction from 1080p). The relatively smaller drop from 1080p to 1440p at Low settings suggests the CPU is beginning to limit performance at 1080p, since the GPU has less work per frame and the frame rate climbs toward the CPU's maximum sustainable throughput.

Medium settings follow a similar pattern: 391 FPS at 1080p, 282 FPS at 1440p, and 175 FPS at 4K. The 1440p Medium result includes a measured minimum of 240 FPS and maximum of 324 FPS, indicating some frame-time variability at this settings tier. Ultra settings produce the lowest frame rates across all resolutions, with 202 FPS at 1080p, 144 FPS at 1440p, and 90 FPS at 4K.

The scaling efficiency from 1080p to 4K at each settings tier shows a consistent pattern. At High settings, 4K delivers 44.4% of the 1080p frame rate. At Low settings, 4K delivers 51.0%. At Medium, 4K delivers 44.8%. At Ultra, 4K delivers 44.6%. This clustering suggests that the RTX 5090 D maintains similar scaling characteristics regardless of settings, with the GPU's 32 GB of GDDR7 memory and 512-bit bus width preventing any memory capacity or bandwidth bottlenecks at 4K.

GPU Role

The NVIDIA GeForce RTX 5090 D is the primary performance driver in this configuration, particularly at 1440p and 4K resolutions. Its 32 GB of GDDR7 memory on a 512-bit bus provides 1.79 TB/s of memory bandwidth, which is more than sufficient for Downfall's texture and geometry demands even at Ultra settings and 4K resolution. The GPU's boost clock of 2407 MHz and base clock of 2017 MHz allow it to sustain high utilization across all tested settings.

The GPU's 21,760 shading units and 680 texture mapping units deliver substantial raw compute throughput, reflected in the 104.8 TFLOPS FP32 performance. This compute capability translates directly into the high frame rates observed in the benchmark data. At 4K Ultra, the system still produces 90 FPS, indicating the GPU is the limiting factor at this resolution/settings combination, while the CPU has sufficient headroom to feed the GPU.

The RTX 5090 D's performance relative to its nearest rivals in synthetic benchmarks shows a tight grouping. Its average benchmark score of 77,712 places it 1.1% above the AMD Radeon RX 6650M XT (76,904) and 1.6% below the AMD Radeon RX 6850M XT (78,940). The GPU sits in the 92nd percentile of all GPUs, confirming its high-end positioning. In Downfall specifically, the GPU's 176 ROPs and 1,636.8 GTexel/s texture rate ensure that pixel fill and texture filtering are rarely bottlenecks, even at 4K with High settings where the system maintains 144 FPS.

Settings Recommendations

Based on the measured frame rates, the High preset at 1440p offers the most balanced experience, delivering 231 FPS with no reported minimum below playable thresholds. This combination provides a substantial visual quality improvement over Medium while maintaining frame rates well above any display refresh rate below 240 Hz. For users with 4K displays, High settings at 144 FPS is equally compelling, as it matches common high-refresh 4K monitor capabilities.

The Ultra preset at 1440p produces 144 FPS, which is identical to the 4K High result. This suggests that Ultra settings impose a similar GPU load at 1440p as High settings do at 4K. For users prioritizing visual fidelity over raw frame rates, 1440p Ultra at 144 FPS is a viable option, though the 4K High setting provides the same frame rate with higher resolution.

At 1080p, even the Ultra preset delivers 202 FPS, meaning all settings tiers at 1080p are playable on high-refresh displays. However, the data shows diminishing returns from Medium (391 FPS) to Low (420 FPS) at 1080p, suggesting that Low settings offer minimal additional performance at this resolution. The Medium preset at 1440p (282 FPS) and 4K (175 FPS) both show measured minimum frame rates (240 FPS and 149 FPS respectively) that remain well above 60 FPS, indicating consistent frame pacing.

For maximum visual quality on a 4K display, the High preset at 144 FPS is the recommended starting point, with Ultra available at 90 FPS for users who prioritize image quality over frame rate. The Low preset is only advisable for competitive play at 1080p or 1440p, where the 420 FPS and 345 FPS results respectively provide the lowest input latency possible with this hardware.

How This Combo Ranks

This configuration ranks 27th out of 2,928 tested combos in Downfall, placing it in the top 0.9% of all system configurations. This ranking reflects the synergy between the Ryzen 7 7800X3D and RTX 5090 D, with the CPU's 96 MB of L3 cache providing the low-latency memory access that benefits game workloads, while the GPU's massive memory pool and bandwidth prevent any resolution-related bottlenecks.

The CPU's average benchmark score of 33,079 places it in the 83rd percentile of all CPUs, with nearest rivals including the AMD Ryzen 7 8700G (33,089, 0% delta), Intel Core i7-13650HX (33,089, 0% delta), AMD Ryzen 7 7745HX (33,091, 0% delta), and AMD Ryzen 9 PRO 6950H (33,201, -0.4% delta). This tight grouping indicates that the 7800X3D's performance is competitive with other high-end chips, though its 3D V-Cache design provides specific advantages in gaming workloads that synthetic benchmarks may not fully capture.

The GPU's ranking context shows it outperforms the AMD Radeon RX 6650M XT by 1.1% and trails the AMD Radeon RX 6850M XT by 1.6% in average benchmark scores. Despite these close synthetic scores, the RTX 5090 D's 32 GB of VRAM and Blackwell architecture provide advantages in real-world gaming scenarios, particularly at high resolutions where memory capacity and bandwidth are critical.

CPU Role

The AMD Ryzen 7 7800X3D's 8 cores and 16 threads, based on the Zen 4 Raphael architecture, provide strong single-threaded and multi-threaded performance for Downfall. The CPU's base clock of 4.20 GHz and boost clock of 5.00 GHz, combined with 96 MB of shared L3 cache, deliver the low-latency memory access that benefits game workloads. The 5 nm process node and 11,270 million transistors on a 71 mm² die demonstrate the efficiency of this design.

Synthetic benchmarks show the CPU's capabilities: Cinebench R23 multicore score of 16,817 and singlecore score of 1,713, Geekbench multicore of 15,610 and singlecore of 2,426, and 3DMark 16-thread score of 7,980. The PassMark multithread score of 34,293 and single-thread score of 3,759 further confirm the CPU's balance between parallel and single-threaded performance. The 16 threads and 8 cores provide sufficient parallelism for modern game engines, while the high boost clock ensures responsive single-threaded performance for game logic and physics.

In Downfall, the CPU's role becomes evident at lower resolutions and settings. At 1080p Low, the system achieves 420 FPS, likely approaching the CPU's maximum frame generation capability. The 1080p Medium result of 391 FPS and 1080p High result of 324 FPS show the CPU can sustain high frame rates even when the GPU has reduced workload per frame. At 1440p and above, the GPU becomes the primary constraint, as evidenced by the frame rate scaling patterns. The CPU's 83rd percentile ranking and its performance parity with rivals like the Ryzen 7 8700G and Core i7-13650HX confirm it is not a bottleneck in this configuration for most scenarios.
