Fortnite

Fortnite, when paired with the Intel Core i5-14600K and NVIDIA GeForce RTX 5090 D, exhibits performance characteristics that shift dramatically based on resolution and quality settings. The measured data reveals a system capable of extreme frame rates at lower resolutions, while the 4K Ultra preset presents a significant challenge. This analysis breaks down the measured FPS across all configurations, examines the roles of the CPU and GPU, and contextualizes the combo's standing against 2,740 other tested configurations.

Resolution Scaling

The transition from 1080p to 4K produces a substantial and consistent drop in frame rates across all settings, indicating a clear shift in system bottleneck. At the Low preset, the average FPS falls from 512 at 1920x1080 to 175 at 3840x2160, a reduction of approximately 65.8%. This steep decline suggests that while the CPU is capable of feeding the GPU at lower resolutions, the rendering load at 4K quickly overwhelms the graphics card.

The scaling pattern becomes more pronounced when examining the High preset. Average frame rates drop from 285 at 1080p to 181 at 1440p, and finally to 96 at 4K. The drop from 1440p to 4K represents a 46.9% decrease in performance, while the 1080p to 1440p drop is 36.5%. This non-linear scaling indicates that the RTX 5090 D's rendering capabilities are being taxed progressively harder as pixel count increases, moving the system from a CPU-bound state at 1080p to a GPU-bound state at 4K.

The Medium preset's minimum FPS figures provide additional insight into this behavior. At 1920x1080, the minimum FPS is 312, which is 84.8% of the average (368). At 2560x1440, the minimum drops to 199, representing 85.0% of the average (234). However, at 3840x2160, the minimum FPS of 105 is only 85.4% of the average (123), showing that frame time consistency is maintained even as the overall frame rate plummets.

The Ultra preset exhibits the most severe scaling. The 4K average of 63 FPS is exactly half of the 1440p average of 120 FPS, which in turn is only 33.5% of the 1080p average of 188 FPS. This pattern confirms that at 4K Ultra, the RTX 5090 D is the definitive limiting component, as the GPU's compute resources are saturated by the combination of high resolution and maximum visual fidelity. The data suggests that for competitive play at high refresh rates, 1080p or 1440p with lower settings is necessary, while 4K is only viable at reduced quality presets.

FAQ

Q: What is the highest average frame rate achievable with this combo?

A: The highest measured average FPS is 512, achieved at 1920x1080 with the Low preset. This is more than double the 240 FPS typically considered smooth for competitive gaming.

Q: How does the 4K Ultra preset compare to 4K Low?

A: The 4K Ultra preset produces an average of 63 FPS, which is only 36.0% of the 175 FPS average achieved at 4K Low. This represents a substantial 112 FPS difference between the lowest and highest quality settings at the same resolution.

Q: Is the system CPU-bound or GPU-bound at 1440p Medium?

A: At 2560x1440 Medium, the average FPS is 234 with a minimum of 199. The relatively high frame rate and the fact that the GPU is not fully saturated, as evidenced by the jump to 332 FPS at Low settings, suggests the system is becoming GPU-bound but still has CPU headroom.

Q: What is the frame rate consistency like at 4K Medium?

A: The 4K Medium preset shows an average FPS of 123, with a minimum of 105 and a maximum of 142. The 37 FPS spread between minimum and maximum indicates moderate frame time variance, which is typical for a GPU-heavy workload at this resolution.

Q: How many total configurations does this combo rank against?

A: This specific combination of Intel Core i5-14600K and NVIDIA GeForce RTX 5090 D ranks 17th out of 2,740 tested combos in Fortnite.

Q: Does the CPU hold back the GPU at 1080p Low?

A: The 512 FPS average at 1080p Low is exceptionally high, but it is likely near the practical limit for the CPU's single-thread performance. The data shows a clear ceiling effect, as the jump from 1080p Low to 1440p Low only drops FPS to 332, a 35.2% reduction, which is less than the pixel count increase of 77.8%.

GPU Role

The NVIDIA GeForce RTX 5090 D, built on the Blackwell 2.0 architecture with a 5 nm process, is the dominant force in this system's performance. Its 32 GB of GDDR7 memory on a 512-bit bus provides 1.79 TB/s of bandwidth, a figure that becomes critical at 4K resolutions where texture data and geometry require massive data throughput. The measured FPS at 4K Ultra (63 FPS) versus 4K Low (175 FPS) demonstrates that the GPU's raw compute and memory bandwidth are the primary determinants of performance in this title.

The GPU's clock speeds play a role in the scaling behavior observed. With a base clock of 2017 MHz and a boost clock of 2407 MHz, the RTX 5090 D can dynamically adjust its frequency based on thermal and power headroom. The 104.8 TFLOPS of FP32 compute power is substantial, but the 4K Ultra preset still manages to reduce average FPS to 63, highlighting how demanding Fortnite's highest settings are on pixel fill rate and shader complexity.

The 176 ROPs and 680 TMUs are directly relevant to the resolution scaling data. At 1080p, the pixel count is manageable, allowing the GPU to achieve 512 FPS at Low settings. At 4K, the pixel count quadruples, and the ROP throughput becomes a limiting factor, particularly at Ultra settings where overdraw and post-processing effects increase the pixel workload. The 423.6 GPixel/s pixel rate provides a theoretical ceiling that explains why 4K Ultra cannot exceed the measured 63 FPS average.

The 92,200 million transistors on a 750 mm² die indicate a highly complex processor, and the 1.79 TB/s memory bandwidth is essential for feeding the 21760 shading units. The data shows that the RTX 5090 D is well-suited for 1440p gaming, where it delivers 181 FPS at High settings, but users targeting 4K must be willing to sacrifice visual fidelity to achieve playable frame rates.

Settings Recommendations

Based on the measured FPS data, the optimal settings balance depends entirely on the user's target resolution and refresh rate. For 1080p displays with a 240 Hz refresh rate, the Medium preset delivers an average of 368 FPS, providing ample headroom above the refresh rate while maintaining better visual quality than Low. The High preset at 285 FPS also exceeds 240 Hz, but the Medium preset's minimum FPS of 312 ensures smoother frame delivery.

For 1440p users with a 165 Hz display, the High preset at 181 FPS is the recommended choice, as it exceeds the refresh rate while providing good visual detail. The Medium preset at 234 FPS offers even more headroom but with reduced visual quality. The Ultra preset at 120 FPS is not recommended for high refresh rate monitors but could be viable for 120 Hz displays, though the drop in minimum FPS (not measured for Ultra) might introduce stutter.

For 4K gaming, the Medium preset at 123 FPS is the only viable option for smooth gameplay, as it exceeds the 60 FPS threshold by a comfortable margin and maintains a minimum FPS of 105. The High preset at 96 FPS is playable but may show occasional dips below 60 FPS in demanding scenes. The Ultra preset at 63 FPS is only suitable for cinematic experiences or games where frame rate is less critical, as the low average leaves little room for frame time spikes.

The data strongly suggests that the Low preset at 4K (175 FPS) is overkill for most displays, as it sacrifices visual quality unnecessarily. The Medium preset offers a 70.3% improvement in FPS over High at 4K (123 vs 96) while still providing acceptable visual fidelity for a competitive title like Fortnite. For users with variable refresh rate displays, the Medium preset at any resolution provides the best balance of performance and visual quality.

Measured FPS Breakdown

At 1920x1080, the measured average FPS is 512 for Low, 368 for Medium, 285 for High, and 188 for Ultra. The Medium preset shows a minimum of 312 and a maximum of 423, indicating a 111 FPS range. This resolution is clearly CPU-limited at lower settings, as the 512 FPS average is likely near the maximum achievable with this processor's single-thread performance.

At 2560x1440, the average FPS is 332 for Low, 234 for Medium, 181 for High, and 120 for Ultra. The Medium preset's minimum is 199 and maximum is 269, a 70 FPS range. The transition from Low to Medium at 1440p results in a 29.5% performance drop, while Medium to High costs 22.6%, and High to Ultra costs 33.7%, showing that the Ultra preset is disproportionately demanding.

At 3840x2160, the average FPS is 175 for Low, 123 for Medium, 96 for High, and 63 for Ultra. The Medium preset's minimum is 105 and maximum is 142, a 37 FPS range. The scaling from Low to Medium at 4K is a 29.7% drop, Medium to High is 22.0%, and High to Ultra is 34.4%. This pattern mirrors the 1440p results, confirming that Ultra settings impose a consistent performance penalty regardless of resolution.

The data shows that the jump from 1080p to 1440p at the same settings yields a 35.2% FPS reduction at Low, 36.4% at Medium, 36.5% at High, and 36.2% at Ultra. The jump from 1440p to 4K is more severe: 47.3% at Low, 47.4% at Medium, 47.0% at High, and 47.5% at Ultra. This consistent 47% reduction from 1440p to 4K across all settings indicates that the pixel count increase is the dominant factor, and the GPU's memory bandwidth plays a crucial role in maintaining this scaling pattern.

CPU Role

The Intel Core i5-14600K, with 14 cores and 20 threads, provides substantial multi-threaded capability, but Fortnite's performance is more dependent on single-thread speed. The CPU's boost clock of 5.30 GHz is critical for maintaining high frame rates at lower resolutions, as evidenced by the 512 FPS at 1080p Low. The Raptor Lake architecture's 24 MB of shared L3 cache helps reduce memory latency, which is beneficial for the game's draw call processing.

The CPU's benchmark scores contextualize its performance. The Cinebench R23 multi-core score of 24491 and single-core score of 2064 indicate strong all-around capability. The PassMark single-thread score of 4270 places it in the 90th percentile of all CPUs, which directly correlates with the high frame rates observed at 1080p. The CPU's 125 W TDP suggests it can sustain high clocks under load, preventing frame rate drops during intense combat scenarios.

The data reveals that the CPU is not the primary bottleneck at 4K, as the GPU's rendering load dominates. However, at 1080p Low, the 512 FPS average is likely limited by the CPU's ability to process game logic and issue draw calls. The 20 threads are sufficient for Fortnite's parallel workloads, but the single-thread performance is the limiting factor at these extreme frame rates.

The Core i5-14600K's 3.50 GHz base clock ensures adequate performance even under sustained load, while the 5.30 GHz boost clock provides the burst performance needed for high-refresh-rate gaming. The DDR4 and DDR5 memory support allows for flexibility, though the memory bandwidth is not a limiting factor in this game based on the measured data. The CPU's 90th percentile ranking versus all CPUs confirms its strong position for gaming workloads.
