Downfall

Downfall, a 2016 horror title, places the Intel Core i7-13700K and AMD Radeon RX 6600 XT combination in a demanding position. The benchmark data shows a pairing where the CPU's immense headroom is frequently left untapped, leaving the GPU as the primary arbiter of frame rates across most settings. This analysis breaks down the measured performance, revealing a system that is exceptionally capable at mainstream resolutions but struggles to maintain fluidity at the extreme end of the spectrum.

Resolution Scaling

The progression from 1920x1080 to 3840x2160 illustrates a classic shift in system bottleneck. At 1080p with Low settings, the combo achieves an average of 193 FPS, a figure that drops to 133.7 FPS at 2560x1440 and further to 83.8 FPS at 4K. This scaling pattern—a 30.7% reduction from 1080p to 1440p, followed by a 37.4% reduction from 1440p to 4K—indicates that the rendering load is scaling heavily with pixel count, which points directly at the GPU as the limiting factor.

The story becomes more pronounced when examining the Ultra preset. The average frame rate plummets from 82.7 FPS at 1080p to 59.3 FPS at 1440p, a 28.3% drop. Moving to 4K Ultra yields just 35.4 FPS, a catastrophic 57.2% reduction from the 1080p result. This steep falloff suggests that the Radeon RX 6600 XT's memory bandwidth and compute resources are being saturated by the combination of high resolution and intensive graphical effects. The data indicates that the CPU is not the constraint here; if it were, the frame rate would remain relatively flat as resolution increases, since the CPU's workload is largely independent of pixel count.

The gap between Low and Ultra settings widens dramatically with resolution. At 1080p, the difference is 110.3 FPS (193 vs 82.7). At 4K, the gap narrows to 48.4 FPS (83.8 vs 35.4). This compression at higher resolutions is a textbook sign of GPU limitation, where even lowering settings cannot fully compensate for the sheer number of pixels being processed. The benchmark results confirm that 1080p is the sweet spot for high refresh rate play, while 4K is only viable with significant graphical compromises.

CPU Role

The Intel Core i7-13700K is a 16-core, 24-thread processor based on the Raptor Lake architecture, with a base clock of 3.40 GHz and a boost clock of 5.40 GHz. In Downfall, a game not known for extreme multi-threading demands, the CPU's role is primarily to feed the GPU with draw calls and physics data. The benchmark data shows that even at 1080p Low, the system reaches 193 FPS, which is a high enough frame rate to demonstrate that the CPU is not a bottleneck at this resolution.

The processor's synthetic benchmark scores reinforce its capability. A Cinebench R23 multi-core score of 39000 and a single-core score of 5505 place it in the top percentile of all CPUs, with a percentile rank of 93. This means that in terms of raw processing power, the i7-13700K has substantial headroom for this title. The nearest rival, the Intel Core i7-13700KF, scores a near-identical average benchmark score with a deltaPct of -0.1%, confirming that the chip's performance is consistent within its product stack.

However, the game's performance scaling suggests that this CPU power is rarely the deciding factor. When comparing the 1080p Low result (193 FPS) to the 4K Low result (83.8 FPS), the massive drop indicates that the GPU is working at its limit, while the CPU likely idles with available capacity. The data implies that for Downfall, the Core i7-13700K provides a stable foundation that ensures frame delivery is never CPU-starved, but it does not actively contribute to higher frame rates beyond what the GPU can render.

How This Combo Ranks

Within the benchmark database, this specific combination of the Intel Core i7-13700K and the AMD Radeon RX 6600 XT ranks at 1202 out of 1741 tested combos for Downfall. This places it in the lower third of all system configurations, which is a notable finding given the strength of the CPU. The ranking suggests that the GPU is the limiting factor in this pairing, dragging the overall performance down relative to systems that pair the same processor with a more powerful graphics card.

The combo rank of 1202, with 1741 total combos, means that roughly 69% of tested systems perform better in this game. This is a direct consequence of the GPU's position in the market; the Radeon RX 6600 XT has a percentile rank of 71 against all GPUs, indicating it is better than average but far from top-tier. The data shows a clear mismatch in capabilities: a top-7% CPU paired with a mid-range GPU, resulting in a system that is balanced for 1080p gaming but outclassed at higher resolutions.

This ranking highlights a critical point for potential system builders. While the CPU ensures that the system will not stutter or suffer from frame pacing issues due to processor limitations, the overall experience in Downfall is dictated by the GPU. The benchmark results indicate that to move up this ranking list, a user would need to upgrade the graphics card rather than the processor, as the i7-13700K is already providing all the necessary headroom.

Measured FPS Breakdown

The measured data provides a complete picture of performance across three resolutions and four quality presets. At 1920x1080, the system delivers an average of 193 FPS on Low, 157.8 FPS on Medium, 129.5 FPS on High, and 82.7 FPS on Ultra. These figures show a smooth progression of performance cost, with Ultra representing a 57.2% performance hit compared to Low. For competitive or high-refresh-rate displays, the Low and Medium presets are clearly the most viable, offering frame rates well above 144 Hz.

Moving to 2560x1440, the averages are 133.7 FPS on Low, 109.8 FPS on Medium, 91.9 FPS on High, and 59.3 FPS on Ultra. The drop from 1080p to 1440p is consistent across settings, with an average reduction of roughly 30%. At this resolution, the High preset remains playable, but the Ultra preset dips below the 60 FPS threshold, making it a borderline choice for smooth gameplay. The data indicates that 1440p is a viable resolution for this combo, provided users are willing to adjust settings away from the maximum.

At 3840x2160, the performance picture becomes more challenging. The system averages 83.8 FPS on Low, 72.1 FPS on Medium, 57.5 FPS on High, and 35.4 FPS on Ultra. Only the Low preset provides a consistently smooth experience at 4K. The High preset at 57.5 FPS is just below the 60 FPS target, while Ultra is effectively unplayable for a horror game that relies on atmosphere and smooth motion. The benchmark results clearly show that 4K gaming with this hardware requires significant compromises, with the GPU's 8 GB of VRAM and 256.0 GB/s of bandwidth being insufficient for the highest settings.

GPU Role

The AMD Radeon RX 6600 XT is based on the RDNA 2.0 architecture and features a Navi 23 chip with 2048 shading units, 128 texture mapping units, and 64 raster operation units. It has a base clock of 1968 MHz and a boost clock of 2589 MHz, with 8 GB of GDDR6 memory on a 128-bit bus providing 256.0 GB/s of bandwidth. These specifications place the GPU at a 71st percentile rank among all graphics cards, meaning it outperforms the majority of its peers but is not a high-end solution.

In Downfall, the GPU's role is paramount. The measured FPS data shows that the GPU is the primary bottleneck at all resolutions above 1080p. The performance difference between the Low and Ultra presets at 4K (48.4 FPS) is almost entirely due to the GPU's inability to handle the increased shader complexity and memory pressure. The GPU's 32 ray tracing cores are present, but the game's age means they are likely underutilized; instead, the raw fill rate and memory bandwidth are the key factors.

The GPU's nearest rival, the NVIDIA GeForce GTX 980 Ti, has an average benchmark score of 27956, a deltaPct of 0.1% compared to the RX 6600 XT's 27985. This shows that the AMD card performs essentially identically to a high-end card from a previous generation. However, in Downfall, the RX 6600 XT's performance at 4K Ultra (35.4 FPS) indicates that its 8 GB VRAM buffer may be a limiting factor, as the game's textures and effects at that setting likely exceed the available memory, causing a significant performance drop. The data confirms that for this title, the GPU is the component that determines the overall experience, with the CPU providing ample support but unable to overcome the graphics card's limitations.
