Resolution Scaling

The measured FPS data shows a clear progression as resolution increases. At 1920x1080 with Low settings, the average FPS is 281.5. Moving to 2560x1440 Low, the FPS drops to 202.2. At 3840x2160 Low, it drops further to 124.5. This scaling pattern indicates that the GPU is becoming the primary limiting factor as resolution increases. At 1080p Ultra, the FPS is 116, while at 1440p Ultra it is 83.9, and at 4K Ultra it is 49.9. The drop from 1080p to 4K at Ultra settings is substantial, reflecting the increased pixel throughput required.

The GPU's specifications support this analysis: it has 3840 shading units, 240 TMUs, and 96 ROPs, with a pixel rate of 233.3 GPixel/s and a texture rate of 583.2 GTexel/s. The FP32 performance is 37.32 TFLOPS. The GPU's 16 GB of GDDR6 memory on a 256-bit bus provides 624.1 GB/s of bandwidth. At 1080p, the CPU's 6 cores and 12 threads can keep up with the GPU, but at 4K, the GPU's raw throughput dictates the frame rate. The data shows that the gap between Low and Ultra settings widens at higher resolutions, with 4K Ultra (49.9 FPS) being less than half of 4K Low (124.5 FPS).

The GPU's Geekbench OpenCL score is 139381, and the Vulkan score is 143060. The 3dmark Steel Nomad DX12 score is 4157. The Passmark G3D score is 24176, and the GPU compute score is 13473. The DirectX 9 score is 304, DirectX 10 is 121, DirectX 11 is 249, and DirectX 12 is 93. These scores indicate that the GPU is well-suited for modern APIs, but the older DirectX 11 path may be more relevant for Downfall, given its 2016 release date. The GPU's 60 RT cores and 3840 shading units provide ample compute power. The 16 GB of GDDR6 memory on a 256-bit bus delivers 624.1 GB/s of bandwidth, which is more than sufficient for the textures used in this title.

How This Combo Ranks

In the database of tested combinations for Downfall, this specific pairing of the Intel Core i5-11400F and AMD Radeon RX 7800 XT ranks 634th out of 1741 combos. This places the combo in the upper-middle portion of all tested systems. The GPU's individual percentile is 76, and the CPU's is 75, indicating a balanced pairing. The GPU's average benchmark score is 32619, with nearest rivals including the AMD FirePro S9300 X2 (32540, delta 0.2%), NVIDIA P104-100 (32747, delta -0.4%), NVIDIA T600 Mobile (32849, delta -0.7%), and AMD FirePro S10000 (32388, delta 0.7%). The CPU's average score is 17181, with rivals as previously noted.

The combo rank of 634 suggests that while the individual components are strong, other combinations in the database achieve higher frame rates in Downfall, likely due to more powerful CPUs or GPUs. The measured FPS data shows that the combo can exceed 200 FPS at 1080p Low, but falls to 49.9 FPS at 4K Ultra, which is a significant spread. The GPU's launch MSRP is 499 USD. The GPU's nearest rival, the AMD FirePro S9300 X2, has an average score of 32540, which is a delta of 0.2% from the RX 7800 XT's 32619. The NVIDIA P104-100 has a score of 32747, a delta of -0.4%. The NVIDIA T600 Mobile has a score of 32849, a delta of -0.7%. The AMD FirePro S10000 has a score of 32388, a delta of 0.7%. This shows the RX 7800 XT is tightly clustered with these professional-grade cards in synthetic benchmarks, but in gaming, the RX 7800 XT's architecture provides specific advantages.

Measured FPS Breakdown

The measured FPS data is as follows. At 1920x1080, the average FPS is 281.5 on Low, 231 on Medium, 189.6 on High, and 116 on Ultra. At 2560x1440, the average FPS is 202.2 on Low, 164.1 on Medium, 133 on High, and 83.9 on Ultra. At 3840x2160, the average FPS is 124.5 on Low, 104.5 on Medium, 81.9 on High, and 49.9 on Ultra.

These numbers provide a complete picture of the combo's performance envelope. The data shows that the combo is highly capable at 1080p, with even Ultra settings delivering 116 FPS. At 1440p, High settings deliver 133 FPS, which is excellent for a horror title. At 4K, only Low and Medium settings deliver playable frame rates above 100 FPS, while High and Ultra drop to 81.9 and 49.9 FPS respectively. The GPU's 16 GB of memory is sufficient for all tested settings, and the CPU's 12 threads ensure smooth frame pacing. The benchmark results indicate that users targeting 4K should adjust settings to Medium or Low to maintain high frame rates, while 1080p and 1440p users can enjoy High or Ultra settings. The progression from Low to Ultra at each resolution shows a consistent pattern: the gap between Low and Ultra is 165.5 FPS at 1080p (281.5 minus 116), 118.3 FPS at 1440p (202.2 minus 83.9), and 74.6 FPS at 4K (124.5 minus 49.9). This narrowing gap at higher resolutions confirms that the GPU becomes the dominant constraint as pixel count rises, while the CPU's influence diminishes.
