Downfall

The Intel Core i5-14600K paired with the AMD Radeon RX 5700 XT delivers a playable but inconsistent experience in Downfall, with performance scaling that clearly exposes the GPU as the primary bottleneck at higher resolutions. The data shows a combination that can handle 1080p and 1440p with high refresh rates, but one that struggles to maintain smooth frame rates at 4K, particularly when visual fidelity settings are pushed beyond Medium. This analysis breaks down the measured performance, the role of each component, and what the results mean for a builder considering this pairing.

Resolution Scaling

The frame rate drop from 1080p to 4K is steep and reveals a system that is heavily GPU-limited at higher pixel counts. At High settings, the average FPS falls from 125 at 1920x1080 to 89 at 2560x1440, a reduction of 36 FPS (roughly 29%). Moving from 1440p to 4K at High settings brings the average down to 56 FPS, another 33 FPS drop (about 37%). This progressive decline indicates that the RX 5700 XT’s rendering throughput is the limiting factor, rather than the CPU.

The scaling pattern is consistent across all settings. At Ultra settings, the average FPS goes from 78 at 1080p down to 56 at 1440p, and finally to 35 at 4K. The 4K Ultra result of 35 FPS is below the threshold for a smooth experience, suggesting that this resolution and settings combination is not viable for serious gameplay. In contrast, the 1080p Low average of 187 FPS shows that the CPU is capable of feeding the GPU far more frames than it can process, confirming that the bottleneck shifts entirely to the graphics card as resolution climbs.

The gap between Low and Ultra settings at each resolution also highlights the GPU’s stress. At 1080p, the difference between Low (187 FPS) and Ultra (78 FPS) is 109 FPS, a massive 58% performance hit. At 4K, the same settings difference is 48 FPS (83 to 35), a 58% reduction. The percentage penalty remains similar, but the absolute FPS loss is smaller because the GPU is already overwhelmed at 4K Low, where it can only manage 83 FPS. This indicates that the RX 5700 XT has limited headroom to absorb the increased shading and texture work demanded by higher presets at 4K.

GPU Role

The AMD Radeon RX 5700 XT, built on the RDNA 1.0 architecture with the Navi 10 chip, is the workhorse in this pairing. Its 8 GB of GDDR6 memory on a 256-bit bus provides a memory bandwidth of 448.0 GB/s. In Downfall, a horror title that relies on atmospheric textures and lighting, this bandwidth is sufficient for 1080p and 1440p, but the framebuffer and memory throughput become strained at 4K. The GPU’s clock speeds, with a base of 1605 MHz and a boost of 1905 MHz, allow for solid performance at lower resolutions, but they cannot compensate for the raw compute limitations.

The card’s compute capabilities are defined by its 2560 shading units and 64 ROPs, which deliver a pixel rate of 121.9 GPixel/s and a texture rate of 304.8 GTexel/s. The FP32 performance of 9.754 TFLOPS is respectable for its generation, but the benchmark results show that it is not enough to maintain high frame rates at 4K Ultra in this game. The measured data supports this: the GPU’s percentile ranking among all GPUs is 59, placing it in the upper half but far from the top tier. Its average benchmark score of 16361 is nearly identical to its nearest rivals, such as the AMD Radeon Pro 5600M (16351) and the NVIDIA RTX PRO 6000 Blackwell (16408), indicating that its performance class is well established.

The 8 GB VRAM capacity is a critical factor at 4K. While the data does not show VRAM exhaustion, the significant FPS drop from 83 at 4K Low to 35 at 4K Ultra suggests that the card is struggling with both memory bandwidth and fill rate. The GDDR6 memory running at an effective 14 Gbps is fast, but the 448.0 GB/s bandwidth is a limiting factor for a game that likely requires large texture sets at high resolutions. The GPU’s TDP of 225 W and suggested PSU of 550 W are typical for this class, but the power delivery is irrelevant to the performance ceiling observed.

How This Combo Ranks

In the database of tested combinations, this pairing of the Intel Core i5-14600K and AMD Radeon RX 5700 XT ranks 2760 out of 3716 combos for Downfall. This places it in the 26th percentile of tested systems, meaning that roughly 74% of all tested combos perform better in this specific game. This rank is a clear indicator that while the combo is functional, it is not a high-performance pairing for this title.

The CPU is not the cause of this low rank. The Intel Core i5-14600K sits in the 90th percentile of all CPUs, with an average benchmark score of 48618. Its nearest rivals, such as the Intel Xeon Gold 5318H (48698) and the Intel Core Ultra 5 245 (48995), have virtually identical scores, with delta percentages of -0.2% and -0.8% respectively. This shows that the CPU has ample processing power for gaming. The GPU, however, holds the combo back; the RX 5700 XT’s 59th percentile ranking among GPUs is below the CPU’s 90th percentile, creating a significant imbalance. The data suggests that upgrading the GPU would yield a much larger performance gain in Downfall than upgrading the CPU.

The rank of 2760 out of 3716 is a holistic measure that accounts for the entire system’s performance. It confirms that the RX 5700 XT is the primary constraint, as the CPU is demonstrably capable of much higher frame rates in other scenarios. For a builder, this rank indicates that the combo is suited for 1080p gaming with high settings, but it is not a recommendation for 4K or competitive high-refresh-rate play at Ultra settings.

Measured FPS Breakdown

The measured FPS data provides a detailed look at the performance envelope of this combo across three resolutions and four settings levels.

At 1920x1080, the combo delivers excellent results. Low settings average 187 FPS, Medium averages 153 FPS with a minimum of 130 FPS and maximum of 176 FPS, High averages 125 FPS, and Ultra averages 78 FPS. The minimum FPS data for Medium (130 FPS) shows that even in demanding scenes, the frame rate stays well above 100 FPS, making this resolution ideal for high-refresh-rate monitors. Even at Ultra, the 78 FPS average is smooth, though it may dip below 60 FPS in heavy action sequences, though no min FPS data is provided for Ultra.

At 2560x1440, performance remains strong but shows the GPU’s strain. Low settings average 133 FPS, Medium averages 109 FPS with a minimum of 93 FPS and maximum of 126 FPS, High averages 89 FPS, and Ultra averages 56 FPS. The Medium minimum of 93 FPS indicates that 1440p Medium is a solid target for a consistent experience, while Ultra at 56 FPS is borderline for smooth gameplay, hovering near the 60 FPS threshold. The drop from 89 FPS at High to 56 FPS at Ultra is a 37% reduction, which is significant and suggests that Ultra settings are too demanding for this GPU at this resolution.

At 3840x2160, the combo falls below playable thresholds for most settings. Low settings average 83 FPS, Medium averages 68 FPS with a minimum of 58 FPS and maximum of 78 FPS, High averages 56 FPS, and Ultra averages 35 FPS. The Medium minimum of 58 FPS is just under 60 FPS, indicating frequent dips below the smoothness threshold. High at 56 FPS is technically playable but not ideal, and Ultra at 35 FPS is not suitable for a horror game that relies on smooth motion to maintain tension. The data clearly shows that 4K is only viable at Low or Medium settings, and even then, the frame pacing may be inconsistent.

CPU Role

The Intel Core i5-14600K is a 14-core, 20-thread processor based on the Raptor Lake architecture, manufactured on Intel’s 10 nm process. It has a base clock of 3.50 GHz and a boost clock of 5.30 GHz, with a TDP of 125 W. The CPU’s cache hierarchy includes 80 KB of L1 cache per core, 2 MB of L2 cache per core, and 24 MB of shared L3 cache. This configuration provides ample compute headroom for gaming, as evidenced by its 90th percentile ranking among all CPUs.

In Downfall, the CPU’s role is to feed the GPU with draw calls and game logic. The benchmark results show that at 1080p Low, the combo achieves 187 FPS, which is a ceiling set by the GPU, not the CPU. The CPU’s multi-threaded performance is strong, with a Cinebench R23 multi-core score of 24491 and a Geekbench multi-core score of 16673. The single-thread performance is also impressive, with a Cinebench R23 single-core score of 2064 and a Passmark single-thread score of 4270. These scores indicate that the i5-14600K can handle the single-threaded workloads typical of game engines without becoming a limiting factor.

The CPU’s nearest rivals in benchmark scores, such as the Intel Xeon Gold 5318H and the AMD EPYC 4345P, have nearly identical average scores, with deltas of -0.2% and 0.3% respectively. This shows that the i5-14600K is in a performance tier where CPU differences are negligible for gaming. The fact that the combo ranks 2760 out of 3716 in Downfall is not a reflection of the CPU’s capability but rather the GPU’s inability to keep pace. The data suggests that if the GPU were upgraded, the i5-14600K would have no trouble pushing significantly higher frame rates, as its 5.30 GHz boost clock and 20 threads provide substantial processing power for both current and future game engines.

The CPU’s memory support for DDR4 and DDR5, along with its dual-channel memory bus, ensures that it can feed data to the GPU efficiently, but the bottleneck remains on the graphics side. Ultimately, the i5-14600K is a high-end CPU that is wasted in this pairing, as the RX 5700 XT limits the overall performance to a level that the CPU could easily exceed.
