Downfall

Intel Core i5-12600KF and AMD Radeon RX 6600 XT: this pairing is a solid mid-range foundation for horror titles like Downfall. The data shows a combo that handles 1080p and 1440p with authority, but hits a clear wall at 4K Ultra. The i5-12600KF is a 10-core, 16-thread Alder Lake processor with a base clock of 3.70 GHz and a boost of 4.90 GHz, while the RX 6600 XT is a RDNA 2.0 part with 8 GB of GDDR6 memory on a 128-bit bus. Together, they rank in the 69th percentile of all tested combos in this game, landing at position 1198 out of 1741. This is a configuration built for high-refresh 1440p gaming, not for pushing every pixel at 4K.

CPU Role — cores, clocks, and how they relate to this game's results

The Core i5-12600KF is the engine driving this combo, and its 10 cores and 16 threads are more than sufficient for Downfall. The processor’s 3.70 GHz base clock ramps up to 4.90 GHz under load, which is the key for single-threaded performance. In synthetic tests, the chip scores 1016 in 3dmark_single_thread and 3925 in passmark_single_thread, indicating strong per-core capability. This matters because horror games often rely on a single primary thread for game logic and physics, even when they scale to multiple cores for rendering tasks.

The multi-threaded muscle is also present. The i5-12600KF achieves a cinebench_r23_multicore score of 23444 and a geekbench_multicore score of 12373. This ensures that background tasks, streaming, or any additional load from the game engine won’t cause stutters. Compared to its nearest rival, the Intel Core i9-10900K, the i5-12600KF is effectively tied with a deltaPct of 0. The i5-12600K is just 0.1% behind, while the Core i7-13700H is 0.4% ahead. This means that for Downfall, the CPU is not the bottleneck; it provides a consistent, high-performance baseline that allows the GPU to do its work. The processor’s 20 MB of shared L3 cache further helps by keeping frequently accessed data close at hand, reducing latency in scenes with many entities or complex interactions.

Settings Recommendations — which preset gives the best experience per the measured rows

For a smooth experience, the data points to the High preset at 1440p as the sweet spot. At 2560x1440 with High settings, the combo averages 92.3 FPS. This is well above the 60 FPS threshold for a fluid experience and leaves headroom for dips. Dropping to Low at 1440p pushes the average to 138.3 FPS, which is excellent for high-refresh monitors, but the visual fidelity loss is significant. Medium at 1440p hits 111.1 FPS, a good middle ground, but High offers the best balance of visual quality and performance.

At 1080p, the story is even better. High settings yield 125.4 FPS, and Medium is at 158.5 FPS. Low at 1080p hits 188.8 FPS, which is near the limit of most 144Hz monitors. For those with a 4K display, the High preset at 3840x2160 averages 58.3 FPS. This is playable, but it’s on the edge; any demanding scene could push it below 60. The Ultra preset is not recommended for this combination. At 1080p Ultra, the average drops to 81.2 FPS, at 1440p Ultra it falls to 59.5 FPS, and at 4K Ultra it plummets to 38.6 FPS. The performance cliff between High and Ultra is steep, indicating that the Ultra preset’s extra effects are too taxing for the RX 6600 XT’s 8 GB frame buffer.

Resolution Scaling — how FPS drops from 1080p to 4K and what it says about the limiting component

The FPS scaling across resolutions clearly identifies the GPU as the limiting factor at higher settings. At High settings, the combo delivers 125.4 FPS at 1080p, 92.3 FPS at 1440p, and 58.3 FPS at 4K. The drop from 1080p to 1440p is a 26% reduction, and the drop from 1440p to 4K is a further 37% reduction. This pattern is typical of a GPU-bound scenario; the CPU is capable of feeding frames quickly, but the GPU’s rendering throughput cannot keep up as pixel count increases.

The Low preset shows a different dynamic. At Low, the FPS is 188.8 at 1080p, 138.3 at 1440p, and 84.8 at 4K. The percentage drops are similar, but the absolute numbers are much higher. This suggests that even at Low settings, the GPU is still the primary constraint, though the CPU is starting to become more relevant at 1080p Low where 188.8 FPS is a very high target. The fact that 4K Low (84.8 FPS) outperforms 4K High (58.3 FPS) by a wide margin confirms that the bottleneck is the GPU’s fill rate and memory bandwidth, not the i5-12600KF’s processing power. The RX 6600 XT’s 256.0 GB/s bandwidth and 165.7 GPixel/s pixel rate are simply not enough for 4K Ultra, which demands more than the card can provide.

How This Combo Ranks — use comboRankInGame vs other tested combos

The combo’s position at rank 1198 out of 1741 tested combinations places it in the upper-middle tier of all systems tested in Downfall. This is a respectable standing, but it is not at the top. The ranking reflects the balance of the i5-12600KF and the RX 6600 XT; it is not a flagship pairing, but it is far from a weak one. The data shows that this combo outperforms many others, but it also has clear limitations when pushed to the highest settings and resolutions.

The CPU’s benchmark percentile is 84, meaning it outperforms 84% of all CPUs tested. The GPU’s percentile is 71. This gap suggests that the GPU is the more limiting component in this pairing, which aligns with the resolution scaling analysis. If the goal is to improve performance in Downfall, upgrading the GPU would yield a larger gain than upgrading the CPU. The i5-12600KF is already a strong performer, with an avgBenchmarkScore of 27827, nearly identical to the i9-10900K at 27829. The RX 6600 XT, with an avgBenchmarkScore of 27985, is slightly ahead of the GTX 980 Ti (27956) but behind the RTX 3070 (28238) by 0.9%. This confirms that the combo’s rank is held back by the GPU’s mid-range class.

GPU Role — VRAM, clocks, and how they relate to this game's results

The AMD Radeon RX 6600 XT is a 7 nm RDNA 2.0 GPU with a base clock of 1968 MHz and a boost clock of 2589 MHz. Its 8 GB of GDDR6 memory on a 128-bit bus provides 256.0 GB/s of bandwidth. For Downfall, this configuration is adequate for 1080p and 1440p, but the 8 GB frame buffer becomes a liability at 4K Ultra. The Ultra preset at 4K drops to 38.6 FPS, a clear sign that the card is running out of memory and rendering headroom.

The GPU’s compute power is 10.60 TFLOPS of FP32 performance, which is enough to handle the game’s visual effects at lower presets. The 2048 shading units and 64 ROPs work together to deliver the measured FPS numbers. At 1440p High, the card produces 92.3 FPS, which is a good result. At 4K High, it manages 58.3 FPS, just barely crossing the playable threshold. The card’s 32 ray accelerators are present, but Downfall does not seem to rely heavily on ray tracing, as the performance deltas are more dependent on raw rasterization power and memory bandwidth. The GPU’s passmark_g3d score of 16461 puts it in a competitive position against the GTX 980 Ti, which scores 27956 in avgBenchmarkScore. This is a 0.1% difference, meaning the RX 6600 XT is effectively a modern equal to that older flagship in this title.

Measured FPS Breakdown — resolution by resolution, settings by settings, exact numbers

At 1920x1080, the combo shows its strongest performance. Low settings deliver an average of 188.8 FPS, which is exceptionally high. Medium settings drop to 158.5 FPS, still excellent for a 144Hz display. High settings yield 125.4 FPS, a great result for a quality/performance balance. Ultra settings fall to 81.2 FPS, which is playable but not ideal for competitive play.

At 2560x1440, the numbers remain strong. Low settings average 138.3 FPS, providing a smooth experience. Medium settings produce 111.1 FPS, and High settings hit 92.3 FPS. Ultra settings at 1440p drop to 59.5 FPS, which is just below the standard 60 FPS target and indicates the preset is too heavy for this GPU.

At 3840x2160, the performance takes a significant hit. Low settings average 84.8 FPS, which is surprisingly playable for 4K. Medium settings drop to 70.6 FPS, still within a usable range. High settings fall to 58.3 FPS, on the edge of playability. Ultra settings at 4K produce only 38.6 FPS, which is not a smooth experience. The data clearly shows that this combo is best suited for 1080p and 1440p gaming, with 4K reserved for Low or Medium settings at best.
