Downfall

The Intel Core i5-12400 paired with the AMD Radeon RX 7800 XT delivers a remarkably consistent experience in Downfall, with the data showing that the GPU is the primary driver of performance at higher resolutions while the CPU keeps pace effortlessly at 1080p. The measured results reveal a clear hierarchy where frame rates scale predictably with both resolution and graphical preset, making it a straightforward system to optimize for this horror title.

Resolution Scaling

The FPS data shows a predictable drop as resolution increases, but the magnitude of that drop reveals where the bottleneck lies. Moving from 1080p to 1440p at High settings, the average frame rate falls from 186.7 FPS to 134.9 FPS — a reduction of roughly 28%. The step from 1440p to 4K is more punishing, with High settings dropping from 134.9 FPS to 83.4 FPS, a further 38% decline. This scaling pattern indicates that the Radeon RX 7800 XT is doing the heavy lifting, as the performance penalty aligns with the increased pixel count rather than any CPU limitation.

At 1080p Low, the combo hits 281 FPS, which is an exceptionally high ceiling. The gap between Low and Ultra at 1080p is substantial — Ultra drops to 116.7 FPS, a 58% reduction from Low. This suggests that even at the lowest settings, the system is not CPU-bound, as the i5-12400’s six cores have ample headroom. At 4K, the spread narrows: Low produces 122.5 FPS while Ultra yields just 50.8 FPS. The 4K Ultra figure is the only measured result that falls below 60 FPS, making it the sole point where the GPU truly struggles to maintain smooth gameplay. The data indicates that resolution scaling is smooth and predictable, with the GPU being the limiting factor at 4K, while the CPU remains a non-issue across all tested configurations.

GPU Role

The RX 7800 XT’s 16 GB of GDDR6 memory on a 256-bit bus provides a 624.1 GB/s bandwidth, which is more than sufficient for Downfall’s horror environments, even at 4K. The GPU’s boost clock of 2430 MHz and game clock of 2124 MHz contribute to its raw throughput, and the benchmark scores reflect this: a passmark G3D score of 24176 and a Geekbench OpenCL score of 139381. These numbers place the GPU in the 76th percentile of all GPUs, indicating solid mid-to-high-tier performance.

The memory capacity is the standout feature here. With 16 GB, the GPU avoids any VRAM-related stutters or texture pop-ins that might plague cards with smaller pools at 4K Ultra. The data supports this: at 4K Ultra, the combo still manages 50.8 FPS, which is playable if not ideal. The GPU’s FP32 throughput of 37.32 TFLOPS and texture rate of 583.2 GTexel/s are the theoretical underpinnings of the measured frame rates. When comparing to its nearest rivals, the RX 7800 XT’s average benchmark score of 32619 puts it 0.2% ahead of the AMD FirePro S9300 X2 and 0.7% ahead of the AMD FirePro S10000, while trailing the NVIDIA P104-100 by 0.4% and the NVIDIA T600 Mobile by 0.7%. These deltas are negligible, meaning the card sits in a tightly contested performance band. The GPU’s DirectX 12 Ultimate support and 60 RT cores are relevant for modern titles, though Downfall’s genre does not appear to leverage ray tracing heavily based on the measured FPS.

How This Combo Ranks

Within the database of 1741 tested combinations, this specific pairing of the i5-12400 and RX 7800 XT holds the 647th rank for Downfall performance. This places it in the upper third of all combos tested, which is a solid result for a mid-range CPU paired with a high-mid-range GPU. The rank of 647 out of 1741 means roughly 37% of tested configurations outperform it, while 63% fall behind. Given that the GPU and CPU individually sit in the 76th and 77th percentiles respectively, the combo’s rank is slightly lower than either component’s individual standing, suggesting that the pairing is well-balanced but not exceptional in the context of the full test pool.

The data shows that the bottleneck is clearly the GPU at higher resolutions, as the CPU’s average benchmark score of 19850 is nearly identical to its nearest rival, the Intel Core i7-9700, which scores 19831 with a delta of 0.1%. This means the CPU is not holding back the GPU in any meaningful way. The combo rank indicates that users with higher-end GPUs would see better results, but for this specific pairing, the performance is respectable and consistent across the board.

Settings Recommendations

For the best experience, the data points to Medium settings as the sweet spot. At 1080p Medium, the combo produces 228.2 FPS, which is well above the refresh rate of most monitors. At 1440p Medium, it drops to 163.6 FPS, still exceptionally smooth. Even at 4K Medium, the average is 101.8 FPS, which is perfectly playable on a high-refresh 4K display. Medium settings offer a 45% improvement over High at 4K (101.8 FPS vs 83.4 FPS) without a visually significant hit to quality, based on the measured data.

High settings are viable for those prioritizing visual fidelity, especially at 1080p (186.7 FPS) and 1440p (134.9 FPS). At 4K, High dips to 83.4 FPS, which is still smooth but leaves less headroom. Ultra settings should be avoided at 4K, as the 50.8 FPS average is below the 60 FPS threshold that most players consider the minimum for smooth gameplay. At 1440p Ultra, the 84.1 FPS result is acceptable, but Medium offers nearly double the frame rate at 163.6 FPS. The recommendation is clear: Medium is the optimal preset for this combo, balancing visual quality and performance across all resolutions.

FAQ

*Q: What is the best resolution for this combo in Downfall?*

A: The data shows that 1440p Medium (163.6 FPS) offers the best balance of visual quality and performance. 4K Medium (101.8 FPS) is also viable, but 4K Ultra (50.8 FPS) falls below the 60 FPS threshold.

Q: Is the CPU or GPU the limiting factor at 1080p?

A: At 1080p Low, the combo reaches 281 FPS, indicating that the Intel Core i5-12400 has ample headroom and the Radeon RX 7800 XT is not being pushed to its limits. The CPU’s 12 threads and boost clock of 4.40 GHz are sufficient for this title.

Q: How does the RX 7800 XT compare to its nearest rivals?

A: The GPU’s average benchmark score of 32619 is 0.2% ahead of the AMD FirePro S9300 X2 and 0.7% ahead of the AMD FirePro S10000, while being 0.4% behind the NVIDIA P104-100 and 0.7% behind the NVIDIA T600 Mobile.

*Q: Can this combo handle 4K gaming in Downfall?*

A: Yes, but with caveats. At 4K Medium, it averages 101.8 FPS, which is smooth. At 4K Ultra, it drops to 50.8 FPS, which is below the ideal 60 FPS target.

Q: What is the performance difference between Low and Ultra at 1080p?

A: At 1080p, Low produces 281 FPS while Ultra produces 116.7 FPS. This represents a 58% reduction in frame rate when moving to the highest preset.

Q: Does the 16 GB VRAM make a difference in this game?

A: The 16 GB GDDR6 memory with 624.1 GB/s bandwidth ensures that the GPU does not run out of memory at 4K Ultra, as evidenced by the playable 50.8 FPS result at that setting.

CPU Role

The Intel Core i5-12400 features 6 cores and 12 threads with a base clock of 2.50 GHz and a boost clock of 4.40 GHz. Its 18 MB of shared L3 cache and 10 nm process node contribute to its performance. In synthetic benchmarks, it scores 15935 in Cinebench R23 multi-core and 2249 in single-core, placing it in the 77th percentile of all CPUs. The CPU’s average benchmark score of 19850 is nearly identical to its nearest rivals: it is 0.1% ahead of the Intel Core i7-9700 (19831) and 0.4% ahead of the Intel Core i5-11600K (19771), while trailing the Intel Core i7-8700 by 0.2% and the AMD Ryzen Threadripper PRO 5995WX by 0.4%.

In Downfall, the CPU’s role is to feed the GPU with enough data to maintain high frame rates. The measured results show that at 1080p Low, the system achieves 281 FPS, which is a clear indication that the CPU is not a bottleneck. Even at 1080p Ultra (116.7 FPS), the CPU has no trouble keeping up. The 3DMark scores support this: the CPU scores 5873 in the 16-thread test and 910 in single-thread, showing balanced multi-threaded and single-threaded performance. The CPU’s PCIe Gen 5 support with 16 lanes ensures that the GPU has a fast connection to the rest of the system, though the RX 7800 XT uses PCIe 4.0 x16. The data suggests that the i5-12400 is more than adequate for this title, and any performance limitations at higher resolutions are purely attributable to the GPU’s rendering capabilities.
