Fortnite

The Intel Core i5-9400 and NVIDIA GeForce RTX 5070 combination produces a well-documented Fortnite performance profile in the database. The measured results across three resolutions and four quality presets show the pairing is workable, but the data also exposes a distinct imbalance: the CPU lags the GPU in raw throughput, which shapes the experience more than the flagship graphics card alone. This analysis walks through the measured frame rates, the roles of the two components, and where the combo stands among all tested configurations, using only the numbers contained in the performance record.

Settings Recommendations

The measured rows provide a clear guide to which preset offers the best experience at each resolution. At 1920×1080, the Low preset reaches an average of 290 FPS, the highest figure across the entire dataset. Medium sits at 254 FPS, High at 197 FPS, and Ultra at 130 FPS. The drop from Low to Medium is roughly the area of steepest fall, yet even Ultra remains above 120 FPS. For competitive play, Low maximizes reaction time with minimal input lag, while Ultra still anchors a 120 Hz display. The most balanced experience at 1080p, however, is Medium: it holds 254 FPS with the minimum recorded of 216 FPS, ensuring that even in dense scenes the frame rate stays well above typical refresh rates.

At 2560×1440, the same pattern emerges. Low yields 229 FPS, Medium 162 FPS, High 125 FPS, and Ultra 83 FPS. Medium is again the best compromise: it keeps the average above the 144 Hz threshold while High only reaches 125, which is enough for many monitors but not all. Users with a high-refresh 1440p display should target Medium, as it gives a 162 average with a minimum of 137 FPS, leaving a wide margin before the frame time becomes noticeable.

Moving to 3840×2160, the margin shrinks sharply. Low reaches 121 FPS, Medium 85 FPS, High 66 FPS, and Ultra 44 FPS. The only preset that can satisfy a 60 FPS baseline is Low, and even that is close. Medium enters the 80–90 range, which is playable but not ideal for a competitive title where fluidity is paramount. High barely hits 66 FPS, and Ultra falls well below an acceptable standard. At 4K, the data indicates Low should be selected for a genuinely smooth session; any higher preset will incur noticeable slowdowns in busy lobbies.

The data across all three resolutions shows that Medium is consistently the sweet spot for this pairing—it maintains respectable frame rates while using the GPU’s capacity well. Low is the fallback when absolute maximum speed is required at 1440p or 4K. Ultra is the least efficient choice: its gains in visual detail do not justify the sharp loss in fluidity compared to High, which at 1080p enjoys more than twice the average FPS of Ultra (197 vs 130). The recommendation is to prioritize Medium or High depending on resolution, but never Ultra if frame rate is the primary criterion.

GPU Role

The RTX 5070 is a high-end card per the data. It carries 12 GB of GDDR7 memory on a 192-bit bus, with a bandwidth of 672.0 GB/s. That memory size is generous for Fortnite, which is a last-gen title with modest resource demands. The measured results support this: even at 4K Ultra, the card sustains 44 FPS, indicating that VRAM does not appear to be a limiting factor in this game—otherwise the Ultra preset would show a more severe hit. The GPU’s boost clock is 2512 MHz, while the base sits at 2325 MHz, and the transistor count of 31,100 million on a 5 nm process contributes to a peak pixel rate of 201.0 GPixel/s.

In the measured frame rates, the GPU demonstrates headroom at 1080p and 1440p. For instance, the step from Low to Medium at 1440p cuts the average from 229 to 162 FPS, but both remain far above the 60 FPS floor. This is a signature of a card that is not fully fed, particularly at lower resolutions where the CPU becomes more involved. At 4K, though, the GPU takes charge, and we see scaling that pushes a 121 FPS Low to 85 FPS Medium, to 57 FPS High according to the readout, and finally 44 FPS Ultra. That drop pattern aligns with a GPU-bound scenario—the card’s raw throughput determines the ceiling, and the 44 FPS Ultra result is a direct reflection of the rendering load.

The GPU’s own percentile ranking among all GPUs is 82, meaning it sits in the top 18% of cards. The nearest rivals in average benchmark score are the AMD Radeon Pro 580 and the NVIDIA RTX A500 Mobile, with scores of 40,318, 40,063, 40,870, and 39,568 respectively. The RTX 5070’s average benchmark score of 40,377 falls between these values. That positioning is strong, but the gap to the next level of GPUs is larger than the margin from this card to professional workstations. For Fortnite, the GPU clearly outperforms the CPU in raw compute and provides far more frame rate than the data actually delivers, which is a classic symptom of a CPU-limited scenario.

How This Combo Ranks

The measured combination holds a rank of 826 out of 3,700 total tested combos. That places it above a significant majority of configurations—roughly the top 22% of the field. The rank is a composite indicator of how the CPU and GPU interact in this particular game, and the result is respectable but not exceptional, given the GPU’s own percentile of 82. The CPU only sits at the 47th percentile across all CPUs, so the pairing tiers the performance down.

Because the CPU is a six-core, six-thread model from the Coffee Lake generation, its average benchmark score of 2,254 among all tested processors is close to its nearest rivals. The efficiency of the whole system is limited by the CPU’s ability to feed the GPU in a battle royale scenario where draw calls and physics often stress the processor. The rank of 826 out of 3,700 suggests a configuration that is never far from a mid-high position but stops short of the top tier. The same CPU with a weaker GPU would likely rank lower; the same GPU with a newer high-clock architecture would climb much higher. Therefore, the rank reflects the CPU’s dragging effect rather than a lack of GPU capability.

Comparing to nearest CPU rivals, the i5-9400’s average benchmark score of 2,254 is a strong figure and close to that of the Intel Core i7-1068NG7 (score 2,259) and the Intel Core i7-10710U (score 2,248). Its GeekBench single and multi-core scores are 1,389 and 5,141 respectively, with Cinebench R15 multicore 668 and R20 multicore 2,784. These numbers put it in the same bracket as many mid-range laptop and desktop chips. The ranking of 826 is not explained by the CPU alone, but rather how that CPU handles the continuous threading required by Fortnite. The GPU’s 82nd percentile result suggests that if the CPU bottleneck were removed, the frame rates could improve markedly—except the data here only covers the combo as it was measured.

Measured FPS Breakdown

The database contains twelve measured frame rate averages. The following entries come from the test set, with names and values as provided:

1920×1080

• Low: 290 FPS average
• Medium: 254 FPS average, 216 min, 292 max
• High: 197 FPS average
• Ultra: 130 FPS average

2560×1440

• Low: 229 FPS average
• Medium: 162 FPS average, 137 min, 186 max
• High: 125 FPS average
• Ultra: 83 FPS average

3840×2160

• Low: 121 FPS average
• Medium: 85 FPS average, 73 min, 98 max
• High: 66 FPS average
• Ultra: 44 FPS average

These numbers form a coherent picture: at 1080p, the system delivers a huge margin for high refresh displays, yet it also provides a wide delta between Low and Ultra. The Medium preset’s 216 min in 1080p shows that even the most demanding scenario keeps average above 200, which is exceptional. In 1440p, the same step yields a 137 min and 186 max, meaning the minimum stays above most 144 Hz monitors’ refresh, and the average is 25 FPS higher than High, 77 FPS higher than Ultra. At 4K, the spread is tighter and the quality levels become more distinct: low and medium differ by 36 FPS, while high and ultra further 22 FPS.

It is important to note that the min and max columns for Low and Ultra are not provided in the dataset, so only the averages for those settings should be used for comparison. However, the Medium row across resolutions does allow a direct view of frame pacing at that preset, showing that the frame time is consistent and well above the playable threshold.

Resolution Scaling

The frame rate per resolution is exactly the same across the board: the average values drop consistently as resolution increases, which is expected. From 1080p Low (290) to 1440p Low (229) to 4K Low (121), the trend is linear, but the rate of decline is not scalar. At Medium, 1080p yields 254, 1440p 162, 4K 85. At High, 197, 125, 66. Ultra drops from 130 to 83 to 44. This presents a classic pattern of GPU-bound scaling—to each resolution step, the workload quadruples, but the frame rate does not halve in every case. For example, the 4K result of 121 Low is 58% of the 1080p Low value, and the 1440p result of 229 is 79% of 1080p, which indicates that the CPU is not the dominant at lower resolutions because the GPU can easily keep up with pixel throughput.

The limiting component becomes visible when examining the difference between Low and Ultra at a single resolution. At 1080p, the difference between Low (290) and Ultra (130) is a 160 FPS drop, whereas at 4K the difference between Low (121) and Ultra (44) is but 77 FPS. This asymmetry reaffirms that at 4K, the GPU itself is the limiting factor—reducing quality from Ultra to Low recovers proportionally more than it does at 1080p. If the CPU were the primary constraint, the Low→Ultra gap would stay constant across resolutions. It does not, which paints a picture where the RTX 5070 becomes the bottleneck at 4K, while the i5-9400 becomes the constraint at 1080p and 1440p.

CPU Role

The i5-9400 has six cores, six threads, a base clock of 2.90 GHz and boost clock of 4.10 GHz. That makes it a modestly built desktop chip from the Coffee Lake generation, identified as CU5. It supports dual-channel DDR4 memory with 42.7 GB/s, and its cache hierarchy includes 64 KB L1 per core, 256 KB L2 per core, and 9 MB of shared L3. Its integrated graphics are a UHD 630, but for gaming with a discrete GPU, the iGPU is irrelevant.

The processor’s benchmark scores substantiate its mid-range position: the Cinebench R20 multi-core score is 2,784, R20 single-core 392, and Geekbench multi-core is 5,141. These numbers are close to that of the Intel Core i7-10710U (score 2,248) and the AMD Ryzen 5 PRO 1500 (score 2,246). In fact, the dataset shows that the i5-9400 performs within a hair of these rivals, with deltas of only -0.2%, +0.3%, and +0.4% respectively relative to that group. This is a Chinchilla like the CPU’s performance is competitive with contemporary mobile parts and entry-level desktop chips.

In the context of Fortnite, the CPU is responsible for streaming in the world, managing actors, and running game logic. The measured FPS table shows that at 1080p Low, the system hits 290 FPS, which is far beyond what the GPU would deliver alone—this is typical of an easy-to-render scene where the CPU is fully fed. However, at 4K Ultra, the fps of 44 causes the GPU’s memory and pixel throughput to saturate, while the CPU idles at a lower load. The fact that the 1080p Low and 1440p Low averages are not proportionally as high as the GPU’s raw score would imply also confirms that the CPU is being pushed to its thread capacity. The six-thread architecture can handle a battle-royale queue, but the threading model of Fortnite does not scale perfectly, and the i5-9400’s 47th percentile relative to all CPUs means it lacks the parallel headroom that a twelve-thread or more modern chip would provide.

FAQ

Q: What is the best resolution for the i5-9400 + RTX 5070 in Fortnite?

A: The data shows 1080p Medium delivers 254 FPS average, the lowest among the four presets is 130 FPS Ultra, so 1080p is the strongest overall choice. If you want 1440p, Medium keeps you above 160, but 4K is only viable on Low at 121 FPS average.

Q: Does the CPU bottleneck the GPU in this combo?

A: The dataset implies it does at 1080p and 1440p, since the FPS differences between Low and Medium are larger than the M/F, and the CPU’s percentile is 47 while the GPU’s is 82. The frame rate at 1080p Low (290) exceeds the 4K Medium (85) by a very large margin, indicating that the GPU has much headroom that is limited by the CPU at lower settings.

Q: How much VRAM does the RTX 5070 have, and does it matter?

A: The GPU has 12 GB of GDDR7 memory. For Fortnite’s moderate texture sizes, this is ample; the frame rate does not drop based on the quality settings that would indicate VRAM exhaustion, even at 4K Ultra (44 FPS). The configuration suggests VRAM is not a limiting factor.

Q: What is the CPU’s clock speed and core count?

A: The i5-9400 has 6 cores and 6 threads, with a base clock of 2.90 GHz and boost clock of 4.10 GHz. This is a traditional desktop part, and its six-thread design handles the game, but the frame rate in high-CPU scenarios is limited compared to GPUs that dominate.

Q: How did this combo compare to other tested combinations?

A: This combination is ranked 826 out of 3,700 combos in the database. That places it within the top sector of the dataset but not near the top. The GPU itself ranks in the 82nd percentile, while the CPU sits 47th percentile, so the ranking reflects the CPU’s trailing performance.

Q: Which settings should one avoid for a stable 60 FPS?

A: At 4K, Ultra dips to 44 FPS, which is below 60. Medium produces 85 FPS, High 66 FPS, so anything above Low at 4K is borderline. At 1440p, Ultra at 83 FPS still passes 60, but for strict 60 sustained, High is only 125, grand margin. The only preset that cannot hit 60 is 4K Ultra.

Q: Does the CPU support overclocking?

A: No, the i5-9400 is multiplier-locked, with a locked multiplier, so it cannot be unlocked; it’s also listed as end-of-life, so any if any increase must come from base system board features.

These answers derive exclusively from the data in the dataset, and the reader is encouraged to consider these figures in conjunction with the wider testing context provided in the full report.
