Downfall

How This Combo Ranks

The Intel Core i5-12400F paired with the AMD Radeon RX 7900 XTX achieves a combo rank of 251 out of 1,741 tested combinations in Downfall. This places the pairing in the top 14.4% of all tested configs, a strong showing that underscores the GPU's dominance in this particular horror title. The data positions this combo well ahead of the median tested system, reflecting a hardware pairing that is heavily weighted toward the graphics card's capabilities.

Examining the CPU's synthetic benchmark standing provides context for this ranking. The i5-12400F sits at the 77th percentile among all CPUs, with an average benchmark score of 19,221. Its nearest rivals in the aggregate CPU rankings are the Intel Core i7-8700K (score 19,210, deltaPct 0.1), the Intel Core i5-1335U (score 19,167, deltaPct 0.3), and the AMD Ryzen 5 7533HS (score 19,364, deltaPct -0.7). The deltaPct values are remarkably tight, with the i5-12400F trailing the Ryzen 5 7533HS by only 0.7% while leading the i7-8700K by a mere 0.1%. This indicates that the CPU's compute headroom is essentially on par with those chips, and its 12 threads (6 cores) deliver consistent multi-threaded performance without being a bottleneck in Downfall.

The GPU side of the equation is where this combo shines. The RX 7900 XTX ranks at the 85th percentile among all GPUs, with an average benchmark score of 44,019. Its closest rivals include the NVIDIA GeForce RTX 4090 Mobile (score 43,667, deltaPct 0.8), the AMD Radeon Pro 580 (score 44,195, deltaPct -0.4), and the NVIDIA GeForce RTX 4070 Ti (score 44,900, deltaPct -2). The 7900 XTX leads the RTX 4090 Mobile by 0.8% but trails the RTX 4070 Ti by 2%. This GPU-centric strength, combined with a CPU that is only marginally behind its immediate peers, explains why the combo ranks as high as it does: the graphics card is doing the heavy lifting in Downfall, and the i5-12400F provides enough throughput to keep feeding it frames.

GPU Role

The AMD Radeon RX 7900 XTX is the defining component in this pairing for Downfall. Its 24 GB of GDDR6 memory on a 384-bit bus delivers 960.0 GB/s of bandwidth, which is ample for the game's texture streaming and high-resolution rendering demands. The GPU's clock behavior is notable: a base clock of 1929 MHz, a game clock of 2365 MHz, and a boost clock of 2498 MHz. The memory operates at 2500 MHz, translating to 20 Gbps effective. These clock speeds, combined with 6,144 shading units and 192 ROPs, give the card a pixel rate of 479.6 GPixel/s and a texture rate of 959.2 GTexel/s.

The relationship between these specs and Downfall's measured results is direct. At 1080p Low, the combo produces 362.5 FPS, a figure that climbs as the GPU has less geometry and shading work to process. The 7900 XTX's FP32 performance of 61.39 TFLOPS and FP16 of 122.8 TFLOPS (2:1) indicate raw compute headroom that the game's horror visuals—often relying on dynamic lighting and particle effects—can exploit. The card also supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, meaning it can leverage modern API features in Downfall.

Notably, the GPU's role becomes more pronounced as resolution scales up. The data shows that at 4K Ultra, the average FPS drops to 69.9, which still remains playable but reflects the card's limits under maximum load. The 24 GB frame buffer is never saturated in any tested setting, even at 4K Ultra, which suggests the GPU's compute and memory bandwidth, rather than capacity, are the limiting factors at the highest settings. The card's dual-slot design and two 8-pin power connectors support its 355 W TDP, but those are hardware characteristics that do not directly affect the measured FPS in this analysis.

Measured FPS Breakdown

The measured FPS data for Downfall covers three resolutions and four settings, all with average FPS values (no min or max FPS recorded). At 1920x1080, the combo delivers 362.5 FPS on Low, 296.1 FPS on Medium, 243.4 FPS on High, and 152 FPS on Ultra. These figures illustrate a steady decline as settings increase, with the gap between Low and Ultra being 210.5 FPS, or 58% lower on Ultra.

Moving to 2560x1440, the averages are 257.3 FPS on Low, 212.2 FPS on Medium, 172.8 FPS on High, and 108 FPS on Ultra. The drop from 1080p to 1440p is consistent across settings: Low falls by 105.2 FPS (29%), Medium by 83.9 FPS (28%), High by 70.6 FPS (29%), and Ultra by 44 FPS (29%). This uniformity suggests the GPU's workload scales linearly with pixel count, with no sudden cliffs.

At 3840x2160, the results are 160.6 FPS on Low, 131.7 FPS on Medium, 106.5 FPS on High, and 69.9 FPS on Ultra. The 4K to 1080p ratio shows Low drops by 201.9 FPS (56%), Medium by 164.4 FPS (56%), High by 136.9 FPS (56%), and Ultra by 82.1 FPS (54%). The consistency across settings indicates that the GPU's memory bandwidth and shading units are scaling proportionally with resolution, without any single setting causing a disproportionate penalty.

Ultra settings impose the largest absolute frame cost at every resolution. At 1080p, the difference between High and Ultra is 91.4 FPS; at 1440p, it is 64.8 FPS; at 4K, it is 36.6 FPS. These numbers show that Ultra's additional effects (likely shadow quality and post-processing) exact a higher relative toll at lower resolutions, where the base frame rate is already high.

Resolution Scaling

The FPS drop from 1080p to 4K reveals the limiting component in this pairing. At Low settings, the average FPS declines from 362.5 at 1080p to 160.6 at 4K, a reduction of 55.7%. At Medium, it falls from 296.1 to 131.7, a 55.5% drop. At High, it goes from 243.4 to 106.5, a 56.2% decline. At Ultra, it descends from 152 to 69.9, a 54% decrease. The near-identical percentage drops across all settings—roughly 55-56%—are a strong indicator that the scaling is purely resolution-driven.

This uniform scaling pattern points to the GPU as the limiting component. If the CPU were the bottleneck, the percentage drop from 1080p to 4K would be smaller at lower settings (where the CPU has more headroom to feed frames) and larger at higher settings (where GPU work grows). Instead, the consistent 55% reduction suggests the RX 7900 XTX's pixel throughput—its pixel rate of 479.6 GPixel/s and texture rate of 959.2 GTexel/s—is the binding constraint as the pixel count quadruples from 1080p to 4K.

The i5-12400F's role is limited to ensuring the GPU is fed. At 1080p Low, the 362.5 FPS result indicates the CPU can sustain very high frame rates, but the GPU still scales down proportionally at 4K, meaning the graphics card is not being held back by the processor. The CPU's 6 cores and 12 threads, running at a base of 2.50 GHz and boost of 4.40 GHz, provide sufficient single-thread performance (3dmark single-thread score of 909) to avoid capping the GPU in Downfall.

The data also shows that settings have a compounding effect at higher resolutions. At 1080p, the gap between Low and Ultra is 210.5 FPS; at 4K, the same gap is 90.7 FPS. This narrowing indicates that Ultra settings at 4K push the GPU into a regime where the additional shading and texture work magnifies the resolution penalty. The 4K Ultra result of 69.9 FPS is the only measured value below 100 FPS, suggesting that this configuration is best suited for high-refresh 1440p or standard 60Hz 4K with High settings, where it delivers 106.5 FPS. The combo's overall rank of 251 out of 1,741 confirms that it is a top-tier performer, but the resolution scaling analysis shows its ceiling is firmly in the GPU's domain.
