Fortnite

The Intel Core i5-13400F paired with the NVIDIA GeForce RTX 4070 delivers a robust Fortnite experience, with benchmark results showing a clear progression from GPU-bound 4K output to a more balanced workload at 1080p. The measured data reveals how the system's frame rate scales with resolution, moving from an average of 60.5 FPS at 4K High settings to 183.9 FPS at 1080p High, a nearly threefold increase. This scaling pattern indicates that at 4K, the RTX 4070 is the primary limiting factor, while at 1080p, the CPU's role becomes more prominent. The transition from 1440p to 1080p shows a 54.8% performance uplift in High settings, which is substantial but not linear, suggesting that other system components begin to influence results at lower resolutions.

Resolution Scaling

The frame rate drops from 1080p to 4K are steep and informative. At Low settings, the system produces 335 FPS at 1080p, 216 FPS at 1440p, and 112.3 FPS at 4K. This represents a 35.5% reduction from 1080p to 1440p, and a further 48% reduction from 1440p to 4K. The scaling at Medium settings follows a similar trajectory: 237 FPS at 1080p, 149.4 FPS at 1440p, and 78.2 FPS at 4K. The percentage drops are larger at higher quality presets, indicating that the GPU's rendering workload increases disproportionately with resolution when more visual effects are enabled.

The data suggests that at 4K, the RTX 4070's 12 GB of GDDR6X memory and 504.2 GB/s bandwidth are being utilized heavily, particularly at Ultra settings where the average FPS falls to 40.9. This is the only configuration that dips below the 60 FPS threshold, highlighting the GPU's limitations at the highest fidelity settings in 4K. In contrast, the 1080p results, especially at Low settings, show headroom that is likely constrained by the CPU's single-thread performance, as indicated by its 3dmark_single_thread score of 960. The i5-13400F's 10 cores and 16 threads, with a boost clock of 4.60 GHz, appear sufficient to feed the GPU at lower resolutions, but the scaling curve suggests diminishing returns below 1440p.

How This Combo Ranks

In the benchmark database, this combination of CPU and GPU ranks 427th out of 1564 tested combos for Fortnite, placing it in the top 27.3% of all configurations. This is a solid position, reflecting the balanced nature of the pairing. The CPU itself holds an 82nd percentile ranking among all processors, while the GPU sits at the 81st percentile, indicating that neither component is dramatically outperforming the other in general workloads. However, the combo's specific rank in this game suggests that the pairing is well-matched for Fortnite's engine, which tends to favor higher clock speeds and strong single-core performance.

When examining the CPU's nearest rivals, the i5-13400F's average benchmark score of 25236 is nearly identical to the Intel Core i7-13620H, which scores 25201, a negligible 0.1% difference. It also trails the AMD Ryzen 5 5600X3D by only 0.5% (25365 vs. 25236) and the AMD EPYC 9474F by 0.5% (25103 vs. 25236). These tiny deltas indicate that the i5-13400F is competitively positioned in its segment, and the Fortnite results are likely representative of what these similar processors would achieve with the same GPU. The RTX 4070's nearest rivals show more variance, with the AMD Radeon RX Vega 56 scoring 0.6% higher on average and the NVIDIA GeForce MX570 A scoring 1.9% higher, though these differences are within the margin of error for synthetic benchmarks and do not necessarily translate to real-world gaming deltas.

Q: Can this system handle 4K gaming smoothly?

A: It depends on settings. At 4K High, the average FPS is 60.5, which is playable. At 4K Medium, it improves to 78.2 FPS. However, at 4K Ultra, the average FPS drops to 40.9, which is below the 60 FPS standard for smooth gameplay.

Measured FPS Breakdown

The measured frame rates provide a comprehensive view of the system's capabilities across three resolutions and four quality presets. At 1920x1080, the results are: Low at 335 FPS, Medium at 237 FPS, High at 183.9 FPS, and Ultra at 118.3 FPS. The progression from Low to Ultra shows a 64.7% performance decrease, which is expected given the increased rendering demands. The 1440p results are: Low at 216 FPS, Medium at 149.4 FPS, High at 118.8 FPS, and Ultra at 75.7 FPS. Here, the drop from Low to Ultra is 65%, similar to 1080p, indicating that the relative cost of quality settings remains consistent.

At 3840x2160, the data shows: Low at 112.3 FPS, Medium at 78.2 FPS, High at 60.5 FPS, and Ultra at 40.9 FPS. The drop from Low to Ultra is 63.6%, which is slightly less than the lower resolutions, suggesting that the GPU is hitting a performance ceiling at 4K. The transition from 1440p to 4K at High settings results in a 49.1% FPS reduction, while at Low settings, the reduction is 48%. This consistency implies that the GPU is the primary bottleneck at 4K, with the CPU having minimal impact on the scaling. The min and max FPS values are not provided, so the analysis relies solely on average frame rates, which show a stable and predictable pattern.

GPU Role

The NVIDIA GeForce RTX 4070 is built on the Ada Lovelace architecture with a 5 nm process at TSMC, featuring 35,800 million transistors on a 294 mm² die. It operates at a base clock of 1920 MHz and a boost clock of 2475 MHz, with memory clocked at 1313 MHz and 21 Gbps effective. The GPU's 12 GB of GDDR6X memory on a 192-bit bus delivers 504.2 GB/s of bandwidth, which is a critical factor for Fortnite's texture-heavy environments at 4K. The card has 5888 shading units, 184 TMUs, and 64 ROPs, along with 46 RT cores and 184 tensor cores, enabling DirectX 12 Ultimate support.

In Fortnite, the GPU's role becomes increasingly dominant as resolution increases. At 1080p Low, the system achieves 335 FPS, which is likely near the CPU's maximum output for this game. As resolution climbs, the GPU's workload expands, and at 4K Ultra, the average FPS falls to 40.9, indicating that the GPU's 29.15 TFLOPS of FP32 compute and 455.4 GTexel/s texture rate are fully saturated. The 200 W TDP and 550 W suggested PSU provide adequate power headroom, while the PCIe 4.0 x16 interface ensures sufficient bandwidth. The GPU's passmark_g3d score of 26927 and 3dmark_steel_nomad_dx12 score of 3854 place it in the 81st percentile, reflecting its strong overall performance, but the Fortnite data shows that 4K Ultra is beyond its comfortable range.

Settings Recommendations

Based on the measured FPS data, the optimal settings depend on the target resolution and desired frame rate. For 1080p gaming, High settings at 183.9 FPS provide an excellent balance, offering smooth gameplay on high-refresh-rate monitors without the performance penalty of Ultra, which still delivers a respectable 118.3 FPS. For 1440p, High settings at 118.8 FPS are recommended for most users, as they exceed the 100 FPS threshold for competitive play. Medium settings at 149.4 FPS are an alternative for those prioritizing frame rate, while Ultra at 75.7 FPS is viable for visually demanding scenarios but may feel less responsive.

At 4K, the recommendations shift due to the GPU's limitations. High settings at 60.5 FPS are just above the 60 FPS target, making them the highest quality preset that maintains playability. Medium settings at 78.2 FPS provide a more comfortable margin, while Low at 112.3 FPS is ideal for competitive play at this resolution. Ultra settings at 40.9 FPS are not recommended for standard play, as the frame rate drops below the smoothness threshold. The data indicates that the RTX 4070 is best utilized at 1440p High or 4K Medium, where it delivers strong performance without exceeding its thermal and power envelope. For users with 1080p displays, the system has significant headroom, and even Ultra settings maintain a high frame rate, making the combo highly versatile across different gaming scenarios.
