Fortnite

Fortnite’s performance with the Intel Core i5-12400F and NVIDIA GeForce RTX 4060 reveals a configuration that scales predictably with resolution, showing clear signs of GPU limitation at higher pixel counts while remaining exceptionally capable at 1080p. The measured data provides a complete picture of how this pairing handles Epic’s battle royale, from the silky-smooth low-settings experience to the demanding Ultra preset that pushes the hardware to its limits.

Resolution Scaling

The FPS drop from 1080p to 4K is steep and consistent across all settings, indicating that the RTX 4060 becomes the primary bottleneck as resolution increases. At Low settings, the average frame rate falls from 245 FPS at 1920x1080 to 156 FPS at 2560x1440, a 36% reduction, and then further to 82 FPS at 3840x2160, which is a 67% drop from the 1080p baseline. This pattern strongly suggests that the GPU’s rendering workload, not the CPU, is dictating performance at higher resolutions — the i5-12400F’s 6 cores and 12 threads have ample headroom to feed the graphics card at 1080p, but the RTX 4060’s 8 GB of GDDR6 memory and 128-bit bus width begin to struggle as pixel count climbs.

The Medium settings curve tells a similar story. At 1080p, the average is 173 FPS, dropping to 110 FPS at 1440p (a 36% decline) and then to 58 FPS at 4K (a 66% decline from 1080p). The High preset follows the same trajectory: 134 FPS at 1080p, 85 FPS at 1440p, and 45 FPS at 4K. These consistent percentage drops — roughly one-third from 1080p to 1440p and another half from 1440p to 4K — are classic signs of a GPU-bound scenario. The CPU’s 3DMark single-thread score of 909 and multi-thread score of 5912 are more than sufficient for Fortnite’s engine at these resolutions, so the scaling behavior is almost entirely attributable to the graphics card’s fill rate and memory bandwidth.

Interestingly, the Ultra preset shows the most dramatic scaling cliff. At 1080p, it averages 88 FPS, which is already well below the other settings. At 1440p, it falls to 56 FPS, and at 4K, it bottoms out at 30 FPS. The gap between Ultra and High at 1080p is 46 FPS (134 vs 88), but at 4K, that gap narrows to just 15 FPS (45 vs 30). This compression of performance differences at higher resolutions further confirms that the GPU is the limiting factor — when the render target becomes massive, even the difference between High and Ultra settings matters less because the hardware is already saturated.

GPU Role

The RTX 4060’s specifications align closely with the observed behavior. Its 8 GB of GDDR6 memory operating at 2125 MHz (17 Gbps effective) provides 272.0 GB/s of bandwidth across a 128-bit interface. For Fortnite, this memory configuration appears adequate at 1080p but becomes a constraint at 4K, particularly on Ultra settings where texture and shadow quality demand more memory capacity and bandwidth. The GPU’s boost clock of 2460 MHz and base clock of 1830 MHz are respectable for the Ada Lovelace architecture, and the 3072 shading units deliver 15.11 TFLOPS of FP32 compute — enough for solid 1080p performance but clearly stretched at higher resolutions.

The benchmark results for the RTX 4060 show a PassMark G3D score of 19545, placing it in the 61st percentile of all GPUs. Its nearest rivals in the database include the AMD Radeon HD 7790 (avg score 17666, delta -0.2%) and AMD Radeon 780M (avg score 17588, delta 0.3%), though these comparisons are based on synthetic benchmarks rather than Fortnite-specific performance. The GPU’s 3DMark Steel Nomad DX12 score of 2302 and PassMark DirectX 12 score of 76 provide additional context for its raw capabilities, but the measured FPS data is far more telling for this game.

The fact that the RTX 4060 manages 245 FPS at 1080p Low but only 30 FPS at 4K Ultra highlights the dramatic impact of resolution on this GPU. The 8 GB VRAM is likely a contributing factor at 4K Ultra, where high-resolution textures can exceed the memory capacity, forcing the card to swap data more frequently. The 272.0 GB/s bandwidth is also modest by modern standards, and Fortnite’s UE5 engine with its Nanite and Lumen features (if enabled at Ultra) would stress both memory capacity and bandwidth heavily.

How This Combo Ranks

In the database of tested combos, this pairing of the i5-12400F and RTX 4060 ranks 1995 out of 3700 combinations, placing it in the 54th percentile of all tested configurations for Fortnite. This middling rank is somewhat surprising given the strong 1080p numbers, but it reflects the fact that the combo’s performance degrades significantly at higher resolutions, pulling down its overall standing compared to combos with more powerful GPUs.

The CPU itself sits at the 73rd percentile of all processors, with an average benchmark score of 19039. Its nearest rivals include the AMD Ryzen 5 7535HS (avg score 19047, delta 0%) and Intel Core i5-1335U (avg score 18982, delta 0.3%), showing that the i5-12400F is competitively positioned in synthetic tests. However, the GPU’s 61st percentile ranking (avg score 17639) is the weaker link in this pairing, and the combo rank reflects that imbalance.

What’s notable is that the combo rank of 1995 suggests there are many other configurations that achieve better Fortnite performance, likely those pairing lower-end CPUs with higher-end GPUs. For a 1080p-focused gaming build, this combo would be more than adequate, but the data shows that at 1440p and 4K, it falls behind a significant portion of the tested field. The rank is a holistic measure across all resolutions and settings, so the 4K Ultra result of 30 FPS drags the overall standing down considerably.

FAQ

A: At 2560x1440, the Ultra preset averages 56 FPS, while High averages 85 FPS — a 29 FPS difference. The Medium preset sits between them at 110 FPS, making Medium the best balance for 1440p if frame rate is prioritized over visual fidelity.

Q: Is the CPU or GPU the bottleneck at 4K?

A: The data strongly indicates the GPU is the bottleneck at 3840x2160. The FPS drops from 1080p to 4K are consistent with GPU-bound scaling (roughly 67% reduction across settings), and the i5-12400F’s 6-core/12-thread configuration with a 4.40 GHz boost clock is powerful enough for Fortnite’s engine at any resolution.

Q: What is the combo’s rank among all tested configurations?

A: This combo ranks 1995 out of 3700 tested combos for Fortnite, placing it in the middle of the field. The rank reflects its strong 1080p performance but weaker 1440p and 4K results.

Q: Does the 8 GB VRAM limit performance at 4K Ultra?

A: The 30 FPS average at 3840x2160 Ultra suggests memory capacity is a constraint. The RTX 4060’s 8 GB GDDR6 with 272.0 GB/s bandwidth is likely insufficient for high-resolution textures and effects, contributing to the dramatic performance drop compared to lower settings.

Q: How does the RTX 4060 compare to its nearest rivals in synthetic benchmarks?

A: The RTX 4060 has an average benchmark score of 17639, placing it at the 61st percentile. Its nearest rivals include the AMD Radeon HD 7790 (delta -0.2%) and AMD Radeon 780M (delta 0.3%), but these are synthetic comparisons and do not reflect Fortnite-specific performance.

Settings Recommendations

For the best experience per the measured rows, the Medium preset at 1920x1080 stands out as the optimal choice. It delivers an average of 173 FPS, which is 39 FPS higher than High (134 FPS) and only 72 FPS lower than Low (245 FPS). The Medium preset also provides a minimum FPS of 147 and a maximum of 198, ensuring consistent frame pacing without the dips that might occur on High or Ultra. Given that Fortnite is a competitive battle royale, the extra headroom from Medium over High is valuable for maintaining smooth gameplay during intense build fights and storm circles.

If visual quality is a priority, the High preset at 1080p with 134 FPS average is still highly playable and offers better shadows, textures, and effects than Medium. However, the data shows that Ultra at 1080p (88 FPS) provides diminishing returns — the 46 FPS penalty from High to Ultra is substantial, and the visual difference in Fortnite is often subtle in fast-paced action. For players at 1440p, Medium (110 FPS) is the clear recommendation, as High (85 FPS) dips below the 90 FPS threshold that many competitive players prefer, and Ultra (56 FPS) is too low for responsive gameplay.

At 4K, the data suggests avoiding Ultra entirely (30 FPS) and even High (45 FPS) is marginal. Low (82 FPS) at 4K is the only setting that approaches playable frame rates, but the visual compromise is significant. For this combo, 4K gaming in Fortnite is not a practical use case unless the player accepts Low settings, which defeats the purpose of high-resolution rendering.

CPU Role

The Intel Core i5-12400F plays a supporting role in this combo, providing ample processing power for Fortnite without becoming a bottleneck. Its 6 cores and 12 threads, based on the Alder Lake architecture, operate at a base clock of 2.50 GHz and boost up to 4.40 GHz. The 18 MB of shared L3 cache and per-core L2 cache of 1.25 MB help maintain low latency access to game data, which is crucial for maintaining high frame rates in CPU-bound scenarios.

Synthetic benchmarks paint a picture of a solid mid-range processor. The Cinebench R23 multi-core score of 12380 and single-core score of 1680 indicate strong performance for gaming workloads. The Geekbench multi-core score of 9472 and single-core score of 1964 further confirm its capabilities. The PassMark multithread score of 19433 and single-thread score of 3481 show that this CPU can handle both heavily threaded and lightly threaded tasks with ease.

However, the measured FPS data suggests that the CPU is rarely the limiting factor in Fortnite. At 1080p Low (245 FPS), the CPU still manages to feed the GPU efficiently, and the 3DMark 2-thread score of 1699 and 4-thread score of 3067 indicate strong single-thread performance that Fortnite’s engine relies on. The CPU’s percentile ranking of 73rd among all processors, with an average benchmark score of 19039, places it comfortably ahead of many older and lower-end chips. Its nearest rivals in the database — the AMD Ryzen 5 7535HS (delta 0%) and Intel Core i5-1335U (delta 0.3%) — are similarly positioned, showing that the i5-12400F is competitive within its segment.

The fact that FPS scales so dramatically with resolution (from 245 FPS at 1080p Low to 82 FPS at 4K Low) while the CPU workload remains relatively constant confirms that the GPU is the performance ceiling. The i5-12400F’s job is to keep the frame pipeline full, and it does so effectively, allowing the RTX 4060 to be the sole determinant of frame rate.

Measured FPS Breakdown

At 1920x1080, the combo delivers its strongest results across all settings. The Low preset achieves an average of 245 FPS, the highest measured value in the entire dataset. Medium follows at 173 FPS, with a minimum of 147 and maximum of 198 FPS, indicating consistent performance. High drops to 134 FPS average, while Ultra falls to 88 FPS. This 1080p range shows that the RTX 4060 has substantial headroom at this resolution, with even the most demanding preset remaining above 85 FPS.

At 2560x1440, performance scales down proportionally. Low averages 156 FPS, which is still excellent for competitive play. Medium averages 110 FPS with a minimum of 93 and maximum of 126 FPS, maintaining good consistency. High averages 85 FPS, which is playable but approaching the threshold where frame drops become noticeable. Ultra averages 56 FPS, which is on the edge of playability for a fast-paced game like Fortnite, where quick camera movements can make low frame rates feel stuttery.

At 3840x2160, the combo struggles to maintain playable frame rates on higher settings. Low averages 82 FPS, which is the only 4K setting above the 60 FPS mark. Medium averages 58 FPS, with a minimum of 49 and maximum of 67 FPS, showing noticeable variance that could lead to occasional hitches. High averages 45 FPS, which is borderline for a shooter, and Ultra averages 30 FPS, which is cinematic but not competitive. The data clearly shows that 4K is beyond the comfortable operating range for this GPU in Fortnite, particularly on anything above Low or Medium settings.
