Fortnite

The Intel Core i5-13400F and NVIDIA GeForce RTX 3070 combination delivers a highly playable Fortnite experience across all tested resolutions, but the performance profile reveals a system that is firmly GPU-limited at higher settings while showing surprising CPU headroom at lower presets. The data indicates a balanced pairing, though the scaling patterns suggest that users prioritizing maximum frame rates will need to make deliberate choices about graphical fidelity versus competitive smoothness.

Resolution Scaling

The measured FPS data shows a clear and consistent drop as resolution increases from 1920x1080 to 3840x2160, which is the expected signature of a GPU-bound workload in Fortnite. At High settings, the average frame rate falls from 152 FPS at 1080p to 96 FPS at 1440p, then further to 51 FPS at 4K. This represents a 66% reduction in frame rate from 1080p to 4K at High settings, indicating that the RTX 3070’s rendering throughput is the primary constraint as pixel count rises.

The scaling pattern becomes more telling when examining the Low preset. At 1080p Low, the combo produces 278 FPS, which drops to 176 FPS at 1440p and 93 FPS at 4K. The 1080p-to-1440p drop of 102 FPS (37%) is larger in absolute terms than the 1440p-to-4K drop of 83 FPS (47%), suggesting that at 1080p Low, the CPU begins to play a more significant role. This is further supported by the fact that the 1080p Low result is the only data point where the frame rate exceeds 200 FPS, a threshold that typically requires substantial CPU throughput.

Medium settings show a similar trajectory: 196 FPS at 1080p, 124 FPS at 1440p, and 66 FPS at 4K. The Ultra preset is the most demanding, yielding 100 FPS at 1080p, 64 FPS at 1440p, and just 34 FPS at 4K. Across all settings, the 4K results are roughly one-third to one-half of the 1080p values, confirming that the RTX 3070’s 8 GB of GDDR6 memory and 448.0 GB/s bandwidth become the limiting factor at higher resolutions. The data suggests that for 4K play, users should expect to stay on Low or Medium settings to maintain acceptable frame rates, while 1440p offers a strong compromise between visual quality and performance.

CPU Role

The Intel Core i5-13400F is a 10-core, 16-thread processor from the Raptor Lake architecture, with a base clock of 2.50 GHz and a boost clock of 4.60 GHz. Its benchmark results place it in the 77th percentile among all CPUs, with an average benchmark score of 25292. In 3DMark tests, the CPU scores 7314 with 16 threads and 960 in single-thread, showing a strong multi-threaded capability that is relevant for Fortnite’s background tasks and physics calculations.

The CPU’s role becomes evident when examining the low-resolution, low-settings results. At 1080p Low, the combo reaches 278 FPS, which is the highest measured value in the entire dataset. This suggests that the i5-13400F is capable of feeding the RTX 3070 with enough frames at lower resolutions where GPU load is reduced. The single-thread score of 960 in 3DMark and 3191 in Cinebench R23 indicates solid per-core performance, which is crucial for Fortnite’s main game thread.

However, the CPU is not the primary bottleneck at higher resolutions. The scaling from 1080p to 4K at Low settings (278 to 93 FPS) is a 66% drop, which aligns with GPU-bound behavior. The CPU’s 10 cores and 16 threads, combined with 20 MB of shared L3 cache, provide ample headroom for Fortnite’s engine, but the data shows that increasing resolution places the burden squarely on the GPU. The i5-13400F’s nearest rivals, including the AMD Ryzen 9 6900HS and AMD Ryzen 5 5600X3D, have nearly identical average scores (25284 and 25365, respectively), indicating that this CPU sits in a well-populated performance tier.

How This Combo Ranks

In the overall database of tested combos for Fortnite, this specific pairing of the Intel Core i5-13400F and NVIDIA GeForce RTX 3070 ranks 1592 out of 3700 combinations. This places it in the 43rd percentile of all tested systems, which is a mid-pack position. The rank reflects the balance between the CPU’s 77th percentile standing and the GPU’s 61st percentile among all GPUs.

The GPU’s average benchmark score is 17208, with a percentile rank of 61. Its nearest rivals include the AMD Radeon RX 7600 XT (with a 0.7% higher score) and the NVIDIA GeForce GTX 690 (1% higher). This suggests that the RTX 3070 is positioned in a competitive segment, and the combo’s rank of 1592 is a direct consequence of this GPU’s mid-tier performance relative to the entire database.

The combo’s rank is not exceptional, but it is by no means poor. The data indicates that a significant number of tested combinations outperform this pairing, likely featuring higher-end GPUs or newer CPUs. However, the measured FPS results show that this combo still delivers playable frame rates across all tested settings and resolutions, making the rank more a reflection of the hardware’s position in the broader market than an indictment of its in-game capability.

Measured FPS Breakdown

The measured FPS data provides a comprehensive view of performance across three resolutions and four settings levels. At 1920x1080, the combo delivers 278 FPS on Low, 196 FPS on Medium, 152 FPS on High, and 100 FPS on Ultra. The Medium setting shows a minimum of 166 FPS and a maximum of 225 FPS, indicating some frame time variance but generally smooth performance.

At 2560x1440, the results are 176 FPS on Low, 124 FPS on Medium, 96 FPS on High, and 64 FPS on Ultra. The Medium setting again provides the only measured minimum and maximum values (106 and 143 FPS), suggesting that this resolution and setting combination offers a reasonable balance. The drop from 1080p to 1440p is most pronounced at Low settings (278 to 176 FPS, a 37% reduction), which reinforces the GPU’s growing role as resolution increases.

At 3840x2160, the frame rates fall to 93 FPS on Low, 66 FPS on Medium, 51 FPS on High, and 34 FPS on Ultra. The Medium setting shows a minimum of 56 FPS and a maximum of 76 FPS, which is the only 4K data point with measured variance. These 4K results are notably lower than the 1080p figures, with the Ultra preset dropping below 40 FPS, which would be considered marginal for competitive play but acceptable for less demanding scenarios.

The pattern across all settings is consistent: Low presets yield the highest frame rates, followed by Medium, High, and Ultra. The gap between Low and Ultra is substantial, ranging from 178 FPS at 1080p to 59 FPS at 4K. This indicates that Fortnite’s Ultra settings impose a significant rendering cost, and users should expect to trade visual fidelity for frame rate as resolution increases. The Medium setting appears to be the sweet spot for 1440p, offering 124 FPS with measured frame times between 106 and 143 FPS.

GPU Role

The NVIDIA GeForce RTX 3070 is built on the Ampere architecture with a GA104 chip, featuring 5888 shading units, 184 texture mapping units, and 96 raster output units. Its base clock is 1500 MHz with a boost clock of 1725 MHz, and it operates with 8 GB of GDDR6 memory on a 256-bit bus, providing 448.0 GB/s of bandwidth. The GPU’s FP32 performance is rated at 20.31 TFLOPS, with 46 ray tracing cores and 184 tensor cores.

In the benchmark data, the RTX 3070 scores 22214 in Passmark G3D and 3162 in 3DMark Steel Nomad DX12, placing it in the 61st percentile among all GPUs. Its average benchmark score is 17208, with nearest rivals being the AMD Radeon RX 7600 XT (0.7% higher) and NVIDIA GeForce GTX 690 (1% higher). This positions the RTX 3070 as a solid mid-to-upper-tier GPU, though its 8 GB memory capacity is a potential limitation at 4K with high texture settings.

The GPU’s role in Fortnite is clearly demonstrated by the resolution scaling data. At 1080p Low, the combo achieves 278 FPS, but this drops to 93 FPS at 4K Low, showing that the GPU’s rendering throughput is the limiting factor as pixel count increases. The 34 FPS result at 4K Ultra is particularly telling, as it indicates that the RTX 3070 struggles with the combination of high resolution and maximum settings. The GPU’s 448.0 GB/s bandwidth and 8 GB memory are likely constraints at 4K, where texture data and frame buffer requirements increase significantly.

The GPU’s process node of 8 nm and transistor count of 17,400 million contribute to its performance characteristics, but the data shows that its real-world Fortnite performance is competitive with its direct rivals. The 61st percentile ranking suggests that while the RTX 3070 is not a top-tier GPU, it remains a capable choice for 1080p and 1440p gaming, with 4K performance requiring settings adjustments.
