Downfall

The AMD Ryzen 7 5800X3D and NVIDIA GeForce RTX 4080 combination delivers exceptional performance in Downfall, a 2016 horror title, placing this pairing in the top 9% of all tested combos. The benchmark data reveals a system that is heavily GPU-bound at higher settings, with the CPU providing a robust foundation that never becomes a bottleneck, even at 1080p where frame rates exceed 360 FPS. This analysis breaks down the specific roles of each component, the scaling across resolutions, and the exact performance metrics observed.

CPU Role

The AMD Ryzen 7 5800X3D is a desktop processor from the 5000 series, built on the Zen 3 architecture (codenamed Vermeer) using a 7 nm process at TSMC. It features 8 cores and 16 threads, with a base clock of 3.40 GHz and a boost clock of 4.50 GHz. A defining characteristic is its large 96 MB of shared L3 cache, which is critical for gaming performance, particularly in titles that benefit from large data sets. The processor supports DDR4 memory with a dual-channel bus, providing a memory bandwidth of 51.2 GB/s. It operates with a TDP of 105 W and uses the AMD Socket AM4 interface.

In the context of Downfall, a horror game, the CPU's role is to manage game logic, physics, and AI, while feeding the GPU with draw calls. The data suggests this processor is more than sufficient for this task. At 1080p with Low settings, the system achieves an average of 361 FPS, which is a high frame rate that often exposes CPU limitations in other configurations. However, the 5800X3D's strong multi-threaded performance, evidenced by a Cinebench R23 multicore score of 14317, ensures it can keep up with the GPU's output. Its single-thread performance is also solid, with a Geekbench single-core score of 2017, which is essential for games that rely heavily on a single main thread.

Comparatively, the 5800X3D's average benchmark score of 27896 places it in the 80th percentile of all CPUs. Its nearest rivals include the AMD Ryzen 7 6800U (with a deltaPct of 0), the Intel Core i9-10900K (0.1% faster), and the AMD Ryzen AI 5 PRO 340 (0.1% slower). These scores show the 5800X3D is a very capable gaming CPU, but the performance in Downfall is not dictated by raw CPU power alone. The game's engine, being from 2016, likely does not utilize the 16 threads to their full potential, but the high core count ensures that background tasks and game threads have ample resources. The L3 cache is a key asset here, as horror games often have many unique assets and textures that can be stored in cache for quick access, reducing latency and improving frame pacing. The benchmark results show that even at 1440p High settings, the CPU is not a limiting factor, as the average FPS of 191 is high and consistent with GPU-bound scenarios.

GPU Role

The NVIDIA GeForce RTX 4080 is a high-end graphics card from the GeForce 40-series, based on the Ada Lovelace architecture and the AD103 chip, manufactured on a 5 nm process at TSMC. It comes with 16 GB of GDDR6X memory on a 256-bit bus, yielding a bandwidth of 716.8 GB/s. The GPU has a base clock of 2205 MHz and a boost clock of 2505 MHz. It includes 9728 shading units, 304 texture mapping units, and 112 render output units, alongside 76 RT cores and 304 tensor cores. Its compute power is listed at 48.74 TFLOPS for FP32 operations.

In Downfall, the RTX 4080 is the primary driver of performance at higher resolutions and settings. The data shows a clear pattern: as the workload on the GPU increases (via resolution and settings), the frame rate drops, indicating the GPU is the limiting component. For instance, at 4K Ultra, the average FPS drops to 74, which is a significant reduction from the 119 FPS at 4K High. This is expected, as Ultra settings likely enable more demanding effects like shadows, reflections, and post-processing, which tax the GPU's compute and memory subsystems. The 16 GB of VRAM is more than sufficient for Downfall, even at 4K Ultra, so memory capacity is not a bottleneck. Instead, the performance is limited by the GPU's raw processing power and memory bandwidth.

The GPU's benchmark scores reflect its high-end status. It has a percentile rank of 86 among all GPUs and an average benchmark score of 54247. Its closest rival is the NVIDIA GeForce RTX 4080 SUPER, which is 0.1% faster, while the AMD Radeon Pro W5700X is 1.1% slower. The RTX 4080's performance in DirectX 12 (a Passmark score of 132) indicates strong modern API support, which is relevant for Downfall if it uses a DX12 renderer. However, the game's age means it likely uses DX11, where the card also excels (Passmark DX11 score of 314). The GPU's high texture rate (761.5 GTexel/s) and pixel rate (280.6 GPixel/s) are key for filling frames at high resolutions. The data indicates that at 1080p and 1440p, the GPU is so powerful that it can produce frame rates well above 200 FPS, but the gains from lowering settings become less pronounced as the resolution drops, pointing to a CPU limit at the very low end of settings at 1080p.

Resolution Scaling

The measured FPS data shows a clear trend of decreasing performance as resolution increases, which is typical for a system where the GPU is the primary bottleneck at higher settings. However, the scaling is not uniform across all settings, revealing the nuanced interaction between the CPU and GPU.

At Low settings, the average FPS scales from 361 at 1080p down to 285 at 1440p (a 21% drop), and further down to 178 at 4K (a 38% drop from 1440p). This is a significant drop, but the frame rates are still very high. The 1080p Low result of 361 FPS is likely near the CPU's limit, as the GPU is not heavily loaded at these minimal settings. The transition from 1080p to 1440p shows a moderate drop, but the drop from 1440p to 4K is larger, suggesting the GPU starts to become more relevant even at Low settings due to the increased pixel count.

At Medium settings, the FPS drops from 327 at 1080p to 233 at 1440p (a 29% drop), and then to 145 at 4K (a 38% drop from 1440p). This pattern is similar to Low, but the absolute frame rates are lower, indicating that the GPU is doing more work. The min FPS values at Medium are recorded: 278 at 1080p, 198 at 1440p, and 123 at 4K. These min FPS numbers are crucial for understanding frame pacing, and they show that even at the lowest points, the system maintains playable frame rates above 120 FPS at 4K.

At High settings, the FPS drops from 268 at 1080p to 191 at 1440p (a 29% drop), and then to 119 at 4K (a 38% drop from 1440p). The drop from 1440p to 4K is the most significant in absolute terms (72 FPS), confirming that the GPU is the limiting factor at these settings. The system is still delivering over 100 FPS at 4K High, which is impressive for a demanding setting.

At Ultra settings, the FPS drops from 168 at 1080p to 120 at 1440p (a 29% drop), and then to 74 at 4K (a 38% drop from 1440p). The 4K Ultra result of 74 FPS is the lowest recorded, and it shows that even this powerful GPU is challenged by the most demanding configuration. The scaling from 1440p to 4K at Ultra shows a 46 FPS drop, which is a 38% reduction, consistent with the other settings. This data indicates that Downfall is heavily GPU-bound at 4K, and the RTX 4080's performance scales predictably with resolution. The consistent ~38% drop from 1440p to 4K across all settings suggests that the GPU is the sole bottleneck at these resolutions, and the CPU is not holding back performance.

How This Combo Ranks
