Downfall

# Downfall with Intel Core i7-12700K + AMD Radeon RX 6600 XT

The Intel Core i7-12700K paired with the AMD Radeon RX 6600 XT delivers a broad performance envelope in Downfall, with measured average frame rates ranging from 34.4 FPS at 4K Ultra to 193 FPS at 1080p Low. The combo ranks 1184th out of 1741 tested combinations in this title, placing it in the lower-middle portion of the database, yet the data reveals a configuration that is clearly capable of smooth gameplay at most common resolution and settings pairings. The 12-core Alder Lake processor, with its 3.60 GHz base and 5.00 GHz boost clocks, provides ample headroom, while the Radeon RX 6600 XT's 8 GB of GDDR6 memory on a 128-bit bus with 256.0 GB/s bandwidth becomes the primary constraint as resolution and quality settings escalate.

Resolution Scaling

The measured FPS data shows a predictable yet steep decline as resolution increases from 1920x1080 to 3840x2160, and the magnitude of that drop reveals where the bottleneck lies. At High settings, the average frame rate falls from 128.5 FPS at 1080p to 92.1 FPS at 1440p, a reduction of 36.4 FPS, and then to 60 FPS at 4K, another 32.1 FPS drop. This progression indicates that the GPU is the limiting component, as the CPU's 3DMark single-thread score of 1043 and max-thread score of 9979 suggest it can feed frames faster than the RX 6600 XT can render them at higher pixel counts. The scaling from 1440p to 4K at High settings shows a 34.9% performance loss, which is typical for a GPU with 8 GB of VRAM and 10.60 TFLOPS of FP32 compute when pixel count quadruples.

The Low settings preset exhibits the most dramatic scaling, with 193 FPS at 1080p dropping to 134.5 FPS at 1440p and then to 87.2 FPS at 4K. This 54.8% reduction from 1080p to 4K at Low settings is larger than the 53.3% reduction seen at High settings, suggesting that at lower quality presets the GPU is still the primary limiter but with less shading complexity, the memory bandwidth of 256.0 GB/s becomes more critical. The Ultra preset shows the steepest absolute decline, from 78.7 FPS at 1080p to 57.1 FPS at 1440p and finally 34.4 FPS at 4K, a 56.3% total drop, which strongly indicates that the 8 GB frame buffer and 128-bit memory interface are saturated at maximum quality settings, particularly at 4K where the game's horror environments demand high-resolution textures and effects.

How This Combo Ranks

Within the database of 1741 tested combinations for Downfall, this pairing sits at rank 1184, which places it in the 68th percentile of all combos tested. This ranking is notably lower than what the individual component benchmarks might suggest, as the CPU's percentile versus all CPUs is 89 and the GPU's percentile versus all GPUs is 71. The discrepancy arises because Downfall appears to be a title that responds strongly to GPU memory bandwidth and capacity, and the RX 6600 XT's 128-bit bus and 8 GB VRAM constrain performance in a way that a higher-ranked GPU with more memory bandwidth would not experience. The combo's average benchmark score of 35684 for the CPU and 27985 for the GPU further illustrates that while each component is mid-to-upper tier in isolation, their combined performance in this specific game is moderated by the GPU's memory subsystem.

Compared to the CPU's nearest rivals, the Intel Core i7-12700K shows a delta of -0.3% versus the AMD Ryzen 7 PRO 5845, +0.6% versus the Intel Core i7-13700T, -0.7% versus the Intel Core i5-14500HX, and +0.8% versus the Intel Core i7-13800H. These narrow deltas, all under one percent, indicate that processor choice within this performance class has minimal impact on the combo's ranking in Downfall, reinforcing that the GPU is the dominant factor in the final rank position. The GPU's nearest rivals show similarly tight clustering, with the RX 6600 XT at +0.1% versus the NVIDIA GeForce GTX 980 Ti, +0.4% versus the AMD Radeon R9 M395X, -0.9% versus the NVIDIA GeForce RTX 3070, and -1.5% versus the AMD FirePro S7150. This suggests that swapping the GPU for any of these alternatives would produce nearly identical frame rates in Downfall, with the RTX 3070 potentially offering a marginal improvement of 0.9% based on the delta.

GPU Role

The AMD Radeon RX 6600 XT, built on the RDNA 2.0 architecture with the Navi 23 chip at a 7 nm process node, operates with a base clock of 1968 MHz, a game clock of 2359 MHz, and a boost clock of 2589 MHz. These clocks, combined with 2048 shading units, 128 TMUs, and 64 ROPs, deliver a pixel rate of 165.7 GPixel/s and a texture rate of 331.4 GTexel/s, which are sufficient for 1080p and 1440p gaming but become strained at 4K. The 8 GB of GDDR6 memory running at 2000 MHz (16 Gbps effective) provides 256.0 GB/s of bandwidth across a 128-bit bus, and this memory configuration is the most probable cause of the significant frame rate drops observed at 4K Ultra settings, where the average FPS falls to 34.4.

The GPU's FP32 performance of 10.60 TFLOPS and FP16 of 21.21 TFLOPS (2:1) place it in a capable range for DirectX 12 Ultimate (12_2) titles like Downfall, which was released in 2016 and thus predates some of the more demanding modern rendering techniques. However, the game's horror genre often employs heavy use of shadows, volumetric effects, and texture streaming, which can tax VRAM capacity. The measured data supports this, as the transition from High to Ultra settings at 1080p results in a 49.8 FPS drop (from 128.5 to 78.7 FPS), while the transition from Medium to High at the same resolution shows a 29.8 FPS drop (from 158.3 to 128.5 FPS). This disproportionate penalty at the Ultra preset suggests that the 8 GB frame buffer is being exceeded or that the memory bandwidth is saturated, causing the GPU to spend cycles on memory management rather than rendering.

Measured FPS Breakdown

At 1920x1080, the RX 6600 XT delivers its strongest results, with average FPS of 193 at Low settings, 158.3 at Medium, 128.5 at High, and 78.7 at Ultra. The gap between Low and Medium is 34.7 FPS, while the gap between Medium and High is 29.8 FPS, and the gap between High and Ultra is 49.8 FPS, indicating that the Ultra preset imposes a significantly higher load than the other quality tiers. At 2560x1440, the averages are 134.5 FPS at Low, 114.1 at Medium, 92.1 at High, and 57.1 at Ultra. The scaling from 1080p to 1440p is relatively consistent, with Low losing 58.5 FPS, Medium losing 44.2 FPS, High losing 36.4 FPS, and Ultra losing 21.6 FPS, which shows that higher settings experience smaller absolute losses because they are already closer to the GPU's performance ceiling.

At 3840x2160, the performance drops are more pronounced, with averages of 87.2 FPS at Low, 71.5 at Medium, 60 at High, and 34.4 at Ultra. The 4K Ultra result is the only measured configuration that falls below 60 FPS, making it unsuitable for smooth gameplay, while the 4K High result of 60 FPS is borderline playable but leaves no headroom for demanding scenes. The progression from Low to Ultra at 4K shows a 52.8 FPS total reduction, and the step from High to Ultra at 4K is particularly severe at 25.6 FPS, which is a 42.7% drop. This nonlinearity at 4K Ultra reinforces the conclusion that the GPU's memory bandwidth of 256.0 GB/s is the limiting factor, as the increased texture detail and shadow resolution at Ultra settings overwhelm the 128-bit interface.

Settings Recommendations

For users targeting 60 FPS as a baseline, the measured data indicates that the Ultra preset is only viable at 1080p, where the average FPS of 78.7 provides a comfortable margin, and at 1440p, where the average of 57.1 FPS is slightly below the 60 FPS threshold and may cause noticeable stutter in a horror title where smooth motion is critical for immersion. The High preset is the most balanced option across resolutions, delivering 128.5 FPS at 1080p, 92.1 FPS at 1440p, and exactly 60 FPS at 4K. For users with 4K displays who prioritize visual fidelity, the High preset at 4K offers the best experience per the measured rows, as it maintains 60 FPS average while providing substantially better image quality than the Medium preset's 71.5 FPS or Low preset's 87.2 FPS.

The Medium preset represents a strong alternative for 4K users who want additional performance headroom, with 71.5 FPS average at 3840x2160, which is 11.5 FPS above the High preset's result and only 15.7 FPS below the Low preset's 87.2 FPS. This suggests that Medium at 4K provides the best compromise between visual quality and frame rate stability, as the 71.5 FPS average allows for occasional dips without falling below 60 FPS. At 1440p, the Medium preset's 114.1 FPS average is more than sufficient for high-refresh-rate displays up to 100 Hz, while the High preset's 92.1 FPS supports 90 Hz monitors with a small buffer. For 1080p users with 144 Hz displays, the Low preset at 193 FPS and Medium at 158.3 FPS both exceed the refresh rate, while High at 128.5 FPS is close but may not fully saturate a 144 Hz panel; the Medium preset is therefore the recommended choice for 1080p high-refresh gaming, as it provides 158.3 FPS average, which is 29.8 FPS above High and only 34.7 FPS below Low, with meaningfully better visual quality.
