A: At 2560x1440, the difference between Low (138.5 FPS) and Ultra (54.8 FPS) settings is 83.7 FPS, representing a 60.4% drop in average frame rate when maxing out visual quality.

CPU Role

The Intel Core i5-13400F brings 10 cores and 16 threads to Downfall, running at a base clock of 2.50 GHz and boosting up to 4.60 GHz. This Raptor Lake-S part, built on Intel's 10 nm process, occupies the 82nd percentile among all CPUs in the database, indicating solid mainstream performance for a 65 W desktop processor.

In Downfall, a horror title from 2016, the CPU's role is primarily to maintain consistent frame pacing and avoid bottlenecking the GPU. The i5-13400F's single-thread performance, measured at 960 in 3dmark's single-thread test and 3004 in Cinebench R23 single-core, is more than sufficient for the game's logical and AI workloads. The processor's multi-threaded capability, demonstrated by a Cinebench R23 multi-core score of 21279, provides headroom for background tasks and any game engine threads that scale beyond four cores.

The CPU's memory support spans both DDR4 and DDR5 through a dual-channel bus, which matters for Downfall's level streaming and texture loading. The 20 MB of shared L3 cache helps keep frequently accessed game data close to the cores, reducing latency in scenes with numerous interactive objects. The processor's 3dmark scores scale predictably from 1880 with 2 threads to 7307 with maximum threads, showing that Downfall benefits from additional cores but does not require all 16 threads to maintain playable frame rates.

The fact that this CPU ranks just 0.1% above the Intel Core i7-13620H and 0.5% above the AMD EPYC 9474F in average benchmark score suggests that the i5-13400F delivers competitive processing power for its class. However, the combo's overall rank of 1281 out of 1741 in Downfall indicates that the processor alone does not boost this system into the upper echelon for this specific game.

How This Combo Ranks

The combination of the Intel Core i5-13400F and AMD Radeon RX 6600 XT ranks 1281 out of 1741 tested combos in Downfall, placing it in the 26th percentile of all system configurations tested for this game. This ranking reflects the balance between the CPU's 82nd percentile standing among processors and the GPU's 71st percentile among graphics cards, with the overall system landing lower than either component's individual percentile suggests.

This discrepancy indicates that Downfall's performance profile is not perfectly aligned with the strengths of this hardware pairing. The game's horror genre demands sustained frame rates with minimal stutter, and the measured data shows that the combo achieves this at lower settings but struggles to maintain high FPS at Ultra quality presets. The rank of 1281 suggests that many other combinations of CPUs and GPUs deliver better Downfall performance, likely because the RX 6600 XT's 8 GB VRAM capacity and 128-bit memory bus become limiting factors at higher resolutions and settings.

The CPU's nearest rivals in synthetic benchmarks—the Core i7-13620H, Ryzen 5 5600X3D, EPYC 9474F, and Ryzen AI 5 PRO 340—all fall within 0.5% of the i5-13400F's average score. This tight clustering means that swapping the CPU for any of these alternatives would likely produce nearly identical Downfall frame rates, assuming the GPU remained constant. The combo rank therefore primarily reflects the GPU's contribution to gaming performance rather than the CPU's processing capabilities.

Measured FPS Breakdown

At 1920x1080, the combo delivers its strongest results. Low settings produce an average of 193.6 FPS, which drops to 154.4 FPS at Medium, 130 FPS at High, and 79 FPS at Ultra. The step from High to Ultra represents a 51 FPS loss, or roughly 39%, suggesting that Ultra settings enable effects that disproportionately tax the GPU. Even at the lowest 1080p preset, the frame rate exceeds 190 FPS, indicating that the CPU is not a bottleneck at this resolution.

Moving to 2560x1440, the same pattern holds with lower absolute values. Low settings average 138.5 FPS, Medium delivers 110 FPS, High achieves 92.1 FPS, and Ultra falls to 54.8 FPS. The High to Ultra transition at 1440p costs 37.3 FPS, representing a 40.5% reduction. The scaling from 1080p to 1440p at High settings shows a 37.9 FPS drop, from 130 to 92.1 FPS, which aligns with the increased pixel count straining the GPU's 256.0 GB/s memory bandwidth.

At 3840x2160, performance becomes marginal for smooth gameplay. Low settings average 83.3 FPS, Medium produces 69.3 FPS, High achieves 55 FPS, and Ultra drops to 36.4 FPS. The 4K Ultra result falls below the 40 FPS threshold that many players consider the minimum for acceptable horror game immersion. The gap between Low and Ultra at 4K is 46.9 FPS, representing a 56.3% reduction. Notably, the 4K Low result of 83.3 FPS is still higher than the 1440p Ultra result of 54.8 FPS, illustrating how much impact the Ultra preset has on performance relative to resolution changes.

GPU Role

The AMD Radeon RX 6600 XT, built on the RDNA 2.0 architecture with a 7 nm process, provides the graphical horsepower for this combo. Its 8 GB of GDDR6 memory on a 128-bit bus delivers 256.0 GB/s of bandwidth, which becomes a critical factor in Downfall's higher resolution and quality settings. The GPU's boost clock of 2589 MHz and game clock of 2359 MHz drive its 2048 shading units, 128 TMUs, and 64 ROPs.

The GPU's synthetic benchmark performance places it at the 71st percentile among all graphics cards, with an average score of 27985. Its nearest rival, the NVIDIA GeForce GTX 980 Ti, sits just 0.1% behind, while the RTX 3070 leads by 0.9%. This tight grouping suggests that the RX 6600 XT competes with older flagship cards and newer mid-range offerings, but the benchmark data alone does not capture the VRAM limitations that Downfall exposes at 4K Ultra.

The measured FPS data shows the GPU's scaling behavior across resolutions. At 1080p, the RX 6600 XT has enough bandwidth and compute to push 130 FPS on High settings, but this drops to 55 FPS at 4K High—a 57.7% reduction. The GPU's 10.60 TFLOPS of FP32 compute and 165.7 GPixel/s pixel rate are sufficient for 1080p and 1440p gaming, but the 4K Ultra result of 36.4 FPS reveals that the combination of 8 GB VRAM and 128-bit memory interface bottlenecks the rendering pipeline.

The GPU's DirectX 12 Ultimate support and Vulkan 1.4 API compatibility ensure that Downfall can leverage modern rendering paths. The passmark DirectX 12 score of 61, while lower than the DirectX 11 score of 163, indicates that the game's DX11 path may be more efficient on this hardware. The GPU's 32 ray accelerators provide hardware-accelerated ray tracing, though Downfall's 2016 release predates widespread RT adoption and likely does not utilize this feature.
