# Fortnite with Intel Core i5-10400F + NVIDIA GeForce RTX 5090 D

The pairing of Intel's 6-core Comet Lake CPU with NVIDIA's flagship Blackwell GPU produces a striking split personality in Fortnite: at 1080p the system pushes well past 300 FPS on Low settings, yet at 4K Ultra it drops to 63 FPS average, revealing a configuration where the RTX 5090 D's immense 32 GB VRAM and 1.79 TB/s bandwidth are often left waiting on the i5-10400F's 12 threads. The measured data shows a combo ranking 163rd out of 2,740 tested configurations, a position that reflects the CPU's 68th percentile standing among all processors rather than the GPU's 92nd percentile placement.

FAQ

Q: How does the Intel Core i5-10400F compare to its nearest rivals in synthetic benchmarks?

A: The i5-10400F posts an average benchmark score of 14,185, which places it 0.2% ahead of the Intel Xeon 6756E (14,163) and 0.5% ahead of the AMD EPYC 7552 (14,115). It trails the Intel Core 7 160UL (14,232) by 0.3% and the AMD Ryzen 3 7320C (14,277) by 0.6%, making the differences essentially negligible.

Q: What is the RTX 5090 D's standing relative to other GPUs in the database?

A: The RTX 5090 D holds a 92nd percentile ranking among all GPUs with an average benchmark score of 77,712. It sits 1.1% above the AMD Radeon RX 6650M XT (76,904) but trails the AMD Radeon RX 6850M XT (78,940) by 1.6%, the NVIDIA Tesla P100 PCIe 12 GB (79,396) by 2.1%, and the Tesla P100 PCIe 16 GB (79,605) by 2.4%.

Q: Which resolution and settings combination delivers the highest average frame rate?

A: The 1920x1080 Low preset produces the highest measured average at 305 FPS. The next best is 1080p Medium at 267 FPS, followed closely by 1440p Low at 262 FPS. The lowest average is 4K Ultra at 63 FPS.

Q: Does the RTX 5090 D's 32 GB VRAM matter for Fortnite at these settings?

A: The data shows diminishing returns from the GPU's memory capacity. At 4K Ultra, the system averages 63 FPS despite having 32 GB of GDDR7 memory and 1.79 TB/s of bandwidth. The bottleneck shifts to the CPU's processing throughput, as evidenced by the i5-10400F's single-thread score of 688 in 3DMark and its 12 MB shared L3 cache.

Q: How does the combo's in-game ranking compare to its component percentiles?

A: The combo ranks 163rd out of 2,740 tested combinations, placing it in roughly the top 6% of configurations. This is notably worse than the GPU's 92nd percentile but better than the CPU's 68th percentile, indicating the pairing underperforms relative to what the graphics card alone would suggest.

Q: What is the frame time consistency like at Medium settings?

A: At Medium settings, the measured rows include minimum and maximum FPS values. The 1080p Medium preset shows a range from 227 to 307 FPS with a 267 average, while 1440p Medium spans 195 to 264 FPS with a 230 average. At 4K Medium, the range narrows to 105–142 FPS around a 123 average, showing tighter consistency at higher resolutions.

GPU Role

The NVIDIA GeForce RTX 5090 D brings specifications that would normally dominate any game: a 32 GB GDDR7 frame buffer on a 512-bit bus, 21,760 shading units, and 170 RT cores. Its boost clock reaches 2,407 MHz, and the memory runs at 1,750 MHz with 28 Gbps effective throughput. The pixel rate of 423.6 GPixel/s and texture rate of 1,636.8 GTexel/s provide ample headroom for Fortnite's stylized visuals, yet the measured performance suggests the GPU is rarely the limiting factor in this pairing.

At 1080p Low, the system hits 305 FPS average, which is likely near the practical ceiling for Fortnite's engine on this CPU. The i5-10400F's 6 cores and 12 threads operate at a 2.90 GHz base clock with a 4.30 GHz boost, and its Cinebench R23 multi-core score of 10,283 indicates moderate throughput. The GPU's FP32 compute of 104.8 TFLOPS vastly exceeds what the CPU can feed in frame-to-frame scenarios, particularly in a battle royale where draw calls and physics updates depend on processor speed.

The VRAM capacity becomes relevant when considering the 4K Ultra result of 63 FPS. Fortnite's Ultra preset likely increases texture quality and shadow complexity, but with 32 GB of VRAM available, memory capacity is not the constraint. Instead, the data points to the CPU's single-thread performance: its 3DMark single-thread score of 688 and Geekbench single-core score of 1,420 suggest that the 10th-gen Comet Lake architecture, built on a 14 nm process, struggles to maintain high frame rates when the GPU demands more draw calls at higher resolutions.

The RTX 5090 D's 92nd percentile ranking among GPUs starkly contrasts with the measured 4K Ultra performance. At 1440p Ultra, the system only manages 120 FPS, which is barely half of what the 1440p Low preset achieves at 262 FPS. This pattern indicates that the GPU's raw capabilities—104.8 TFLOPS FP32, 680 tensor cores, and 176 ROPs—are being constrained by the CPU's ability to issue commands. The 12 MB shared L3 cache and dual-channel DDR4 memory support at 42.7 GB/s further limit how quickly data can be fed to the GPU.

Resolution Scaling

The measured FPS data reveals a clear scaling pattern as resolution increases, with the CPU-GPU balance shifting at each step. At 1080p Low, the system averages 305 FPS. Moving to 1440p Low drops this to 262 FPS, a 14% reduction. At 4K Low, the average falls to 175 FPS, representing another 33% drop from 1440p. This scaling suggests that at Low settings, the GPU becomes more involved as pixel count rises, but the CPU still maintains a significant influence.

For Medium settings, the progression is 267 FPS at 1080p, 230 FPS at 1440p, and 123 FPS at 4K. The 1440p to 4K transition shows a 46% performance loss, which is steeper than the 1080p to 1440p drop of 14%. This nonlinear scaling indicates that at 4K Medium, the GPU's rendering workload begins to dominate, though the CPU still prevents the system from reaching what the RTX 5090 D could theoretically deliver.

High settings tell a similar story: 244 FPS at 1080p, 181 FPS at 1440p, and 96 FPS at 4K. The drop from 1080p to 1440p is 26%, while 1440p to 4K is 47%. Ultra settings show the most dramatic scaling: 188 FPS at 1080p, 120 FPS at 1440p, and 63 FPS at 4K. The 1440p to 4K Ultra decline of 47% mirrors the Medium preset's scaling, suggesting that beyond a certain resolution, the GPU's pixel throughput becomes the primary limiter.

The resolution scaling data indicates a system that is CPU-bound at 1080p across all settings. At 1080p Ultra, the system still achieves 188 FPS, which is higher than the 1440p Low result of 262 FPS only when comparing raw numbers—but the relative stability at 1080p suggests the CPU can maintain sufficient frame pacing. At 4K Ultra, the 63 FPS average is the only measured result below 60 FPS, and even that stays above the minimum playable threshold. The lack of min FPS data for most settings (only Medium presets include min/max) limits frame-time analysis, but the available ranges at Medium show 1080p varying by 80 FPS, 1440p by 69 FPS, and 4K by just 37 FPS.

How This Combo Ranks

The combo's rank of 163rd out of 2,740 tested combinations places it in the top 6% of all configurations in the database. This ranking is notable because it sits far below what the RTX 5090 D's individual standing would predict. The GPU's 92nd percentile means it outperforms 92% of all graphics cards in the database, yet this pairing with the i5-10400F achieves a combined position that is approximately 94th percentile—a modest degradation.

The CPU's own ranking helps explain this. With a 68th percentile among all CPUs, the i5-10400F is a mid-range processor from 2020. Its average benchmark score of 14,185 places it in the same performance tier as server processors like the Xeon 6756E and EPYC 7552, but those chips have many more cores for multi-threaded workloads. The i5-10400F's 3DMark 16-thread score of 4,748 and max-thread score of 4,735 show that its 6 cores with Hyper-Threading reach a ceiling around that level.

The gap between component percentiles and the combo's in-game rank suggests that Fortnite's engine is sensitive to both CPU and GPU performance, but the CPU becomes the limiting factor at lower resolutions. At 1080p, where the GPU has less work per frame, the i5-10400F's single-thread capabilities (3DMark single-thread score of 688, Cinebench R23 single-core of 1,451) dictate the maximum frame rate. The RTX 5090 D's 104.8 TFLOPS of FP32 throughput is effectively wasted when the CPU can only generate so many draw calls per second.

Compared to other combos in the database, this pairing performs best at 1080p Low (305 FPS) and worst at 4K Ultra (63 FPS). The 4K Ultra result of 63 FPS is particularly telling—it is only 33% of the 1080p Low result, whereas a purely GPU-bound system might show a 4:1 ratio or worse. This indicates that the CPU mitigates some of the resolution penalty by becoming more of a factor at higher settings, but it also prevents the GPU from reaching its full potential at any resolution.

Settings Recommendations

Based on the measured FPS rows, the Medium preset offers the best balance of visual quality and performance across all resolutions. At 1080p Medium, the system averages 267 FPS with a minimum of 227 FPS and maximum of 307 FPS. This provides a significant margin above 144 Hz refresh rates while maintaining better visual fidelity than Low. The 1440p Medium result of 230 FPS (195–264 FPS range) similarly exceeds high-refresh displays and represents a 12% drop from 1080p Medium—a reasonable trade for the resolution increase.

For users with 4K displays, Medium is the only preset that maintains playable frame rates. The 4K Medium average of 123 FPS with a 105–142 FPS range keeps the experience above 100 FPS, whereas High drops to 96 FPS and Ultra falls to 63 FPS. The jump from 4K Medium to 4K High costs 27 FPS (22% loss), and the jump to Ultra costs another 33 FPS (27% loss from High). This suggests diminishing returns for Ultra settings in Fortnite, where the visual enhancements do not justify the performance penalty.

Low settings are viable for competitive play, especially at 1080p where the system hits 305 FPS. This exceeds the refresh rate of most gaming monitors and provides the lowest input latency. At 1440p Low, 262 FPS still offers a competitive edge, and even 4K Low at 175 FPS is far above what most 4K displays can show. However, Low settings sacrifice shadows, textures, and effects that can impact visibility in a battle royale.

Ultra settings are only recommended for 1080p displays where 188 FPS remains smooth. At 1440p Ultra (120 FPS) and 4K Ultra (63 FPS), the frame rates drop below what most high-refresh users would accept, and the visual improvements over High are marginal. The High preset at 1080p (244 FPS) and 1440p (181 FPS) provides a middle ground, but the data shows Medium delivers the most consistent experience across all resolutions.

Measured FPS Breakdown

At 1920x1080, the system achieves its highest frame rates across all settings. Low settings produce a 305 FPS average, which is the single fastest result in the entire dataset. Medium settings follow at 267 FPS with a measured range of 227 to 307 FPS, showing that the system can occasionally exceed the Low preset's average. High settings average 244 FPS, and Ultra settings average 188 FPS. The spread from Low to Ultra at 1080p is 117 FPS, indicating that settings have a substantial impact even when the CPU is likely the primary bottleneck.

The 2560x1440 resolution shows a similar pattern with lower absolute values. Low settings average 262 FPS, barely 14% below the 1080p Low result, suggesting the GPU can handle the additional pixels without much trouble. Medium averages 230 FPS with a 195–264 FPS range, High averages 181 FPS, and Ultra averages 120 FPS. The 1440p to 1080p ratio at each setting is roughly 0.86 for Low, 0.86 for Medium, 0.74 for High, and 0.64 for Ultra, showing that higher settings amplify the resolution penalty.

At 3840x2160, performance drops significantly. Low settings average 175 FPS, which is still playable but represents a 33% loss from 1080p Low. Medium averages 123 FPS with a 105–142 FPS range, providing the only 4K option with frame-time data. High averages 96 FPS, and Ultra averages 63 FPS. The 4K Ultra result is the only measured average below 100 FPS, and it sits just above the 60 FPS threshold that many consider the minimum for smooth gameplay.

The Medium preset's min/max FPS data reveals interesting consistency patterns. At 1080p, the 227–307 FPS range spans 80 FPS, which is a wide variation that could cause noticeable stuttering on a 240 Hz display. At 1440p, the 195–264 FPS range spans 69 FPS, and at 4K, the 105–142 FPS range spans just 37 FPS. This tightening range at higher resolutions suggests that the GPU's consistent frame pacing at 4K Medium—where the CPU is less likely to cause frame hitches—provides a more stable experience than the higher average frame rates at lower resolutions.
