Fortnite

Fortnite on the Intel Core i5-12400F and NVIDIA GeForce RTX 3080 combination delivers a highly adaptable experience, but the data shows that performance scales dramatically with both resolution and quality settings. At 1080p, this pairing is overwhelmingly GPU-bound at lower presets, while at 4K Ultra, it falls to just 39.5 FPS, indicating a heavy load on the graphics card. The benchmark results place this combo in the 453rd position out of 1564 tested combinations, putting it in the top third of all systems tested for this title. This is a configuration that can handle competitive play at high frame rates or prioritize visual fidelity at lower resolutions, but it cannot do both simultaneously at 4K.

Resolution Scaling

The frame rate drop from 1080p to 4K is steep and reveals the limiting component at each stage. At Low settings, the average FPS falls from 323.4 at 1920x1080 to 207.6 at 2560x1440, a reduction of approximately 36%. Moving from 1440p to 4K Low, the average drops further to 107.9 FPS, another 48% decline. This pattern indicates that the RTX 3080 is the primary bottleneck as resolution increases, since the CPU has less overhead at higher pixel counts.

At High settings, the scaling is similar but with lower absolute numbers. The average at 1080p is 175 FPS, which drops to 110.6 FPS at 1440p (a 37% reduction) and then to 61.6 FPS at 4K (a 44% reduction). The consistent percentage drops suggest that the GPU is doing proportionally more work as pixel count grows, while the CPU maintains a relatively stable level of contribution. The Ultra preset shows the most dramatic scaling, going from 115 FPS at 1080p to 72.2 FPS at 1440p and finally to 39.5 FPS at 4K, with the 4K result being barely playable for a competitive title.

The data indicates that the RTX 3080's 10 GB of GDDR6X memory and 760.3 GB/s bandwidth are adequate for 1080p and 1440p across all settings, but the 4K Ultra result of 39.5 FPS shows a clear limit. The gap between Low and Ultra at 4K is 68.4 FPS, which is significant, but at 1080p that same gap is 208.4 FPS. This widening delta confirms that the GPU is the limiting factor at higher resolutions, particularly when demanding visual effects are enabled.

Q: Does the CPU hold back the GPU at any resolution?

A: At 1080p Low, the 323.4 FPS average suggests the CPU is still keeping pace with the GPU. The i5-12400F's 6 cores and 12 threads, with a boost clock of 4.40 GHz, appear sufficient to feed the RTX 3080 even at high frame rates.

CPU Role

The Intel Core i5-12400F is a 6-core, 12-thread processor from the Alder Lake architecture, with a base clock of 2.50 GHz and a boost clock of 4.40 GHz. Its synthetic benchmark scores show a strong single-thread performance, with a 3dmark single-thread score of 909 and a Cinebench R23 single-core score of 2332. This single-thread strength is critical for Fortnite, which relies heavily on a few primary threads for game logic and physics.

The CPU's multi-threaded capabilities are also solid, with a Cinebench R23 multicore score of 16518 and a Geekbench multicore score of 9138. In the context of this game, the 3dmark 16-thread score of 5895 and max-thread score of 5912 show that scaling beyond 6 cores is minimal, meaning the i5-12400F's 12 threads are more than adequate for Fortnite's workload. The processor ranks in the 77th percentile of all CPUs, with an average benchmark score of 19221, placing it virtually tied with the Intel Core i7-8700K at a 0.1% delta.

In practical terms, the CPU is not the primary bottleneck in this configuration. The measured FPS at 1080p Low (323.4) and 1080p Medium (230.9) shows that the GPU is handling the majority of the rendering load. The CPU's 18 MB of shared L3 cache and support for both DDR4 and DDR5 memory provide enough bandwidth to avoid stuttering, although the specific memory type used was not part of the measured data. The 65W TDP suggests efficient power draw, but this is not a performance metric.

Measured FPS Breakdown

At 1920x1080, the average frame rates are consistently high across all presets. Low settings deliver 323.4 FPS, Medium drops to 230.9 FPS, High comes in at 175 FPS, and Ultra sits at 115 FPS. The spread of 208.4 FPS between Low and Ultra shows that the RTX 3080 has significant headroom at this resolution, and the CPU is able to maintain frame delivery without issue.

Moving to 2560x1440, the averages are 207.6 FPS for Low, 142.6 FPS for Medium, 110.6 FPS for High, and 72.2 FPS for Ultra. The relative performance gap between Low and Ultra narrows to 135.4 FPS, indicating that the GPU is starting to become more saturated. The 1440p High result of 110.6 FPS is particularly notable, as it offers a high refresh rate experience with good visual fidelity.

At 3840x2160, the averages drop significantly. Low settings produce 107.9 FPS, Medium produces 78.7 FPS, High produces 61.6 FPS, and Ultra produces 39.5 FPS. The Low preset at 4K is the only one that remains above 100 FPS, making it the only viable option for smooth 4K play. The Ultra preset at 39.5 FPS is below the 60 FPS threshold that most players consider playable, confirming that this setting is too demanding for this combo at 4K.

How This Combo Ranks

The combination of the Intel Core i5-12400F and NVIDIA GeForce RTX 3080 ranks 453rd out of 1564 tested combos in Fortnite. This places the system in the top 29% of all combinations tested, which is a strong showing given the CPU's mid-range positioning and the GPU's status as a previous-generation high-end part. The rank reflects the measured FPS data, which shows that the combo excels at 1080p and 1440p but struggles at 4K Ultra.

Compared to the CPU's individual percentile (77th) and the GPU's individual percentile (80th), the combo rank is slightly lower, suggesting that the pairing is not perfectly optimized for this specific game. However, the delta between the CPU and its nearest rival, the Intel Core i7-8700K, is only 0.1%, and the GPU's nearest rival, the AMD Radeon Pro Duo, is only 0.2% behind. This indicates that small changes in component selection would not significantly alter the combo's ranking.

The data shows that the combo's performance is heavily influenced by the settings preset, with the 1080p Low result of 323.4 FPS being exceptional and the 4K Ultra result of 39.5 FPS being poor. The rank of 453 suggests that there are 452 other combos that achieve better overall performance across the tested scenarios, likely featuring newer or higher-end GPUs that can handle 4K Ultra more effectively.

Settings Recommendations

For the best balance of visual quality and frame rate, the 2560x1440 High preset is the standout choice, delivering 110.6 FPS. This configuration provides a smooth experience on 100 Hz or 120 Hz monitors while maintaining high-quality textures and effects. If a higher refresh rate is the priority, the 1920x1080 Medium preset at 230.9 FPS is ideal for 144 Hz or 240 Hz displays, offering a significant frame rate boost with only a minor reduction in visual fidelity.

For competitive players who prioritize frame rate above all else, the 1920x1080 Low preset at 323.4 FPS is the clear winner, as it maximizes responsiveness and minimizes input lag. The 4K resolution should only be used with the Low preset, which yields 107.9 FPS, as any higher preset at 4K drops below 80 FPS. The Ultra preset is not recommended at any resolution, as even at 1080p it only achieves 115 FPS, which is lower than the 1440p High result of 110.6 FPS with better visuals.

The data suggests that the RTX 3080 has enough headroom at 1080p to allow for higher settings without sacrificing too much performance. The jump from Medium to High at 1080p costs 55.9 FPS, but the visual improvement is substantial. For most players, 1440p High is the recommended sweet spot, as it balances the GPU's capabilities with the need for smooth gameplay.

GPU Role

The NVIDIA GeForce RTX 3080 is the dominant component in this pairing, and its 10 GB of GDDR6X memory on a 320-bit bus provides 760.3 GB/s of bandwidth. This memory configuration is sufficient for 1080p and 1440p at all settings, but the 4K Ultra result of 39.5 FPS shows that the 10 GB capacity and the GPU's compute power are stretched thin at that resolution. The GPU's 8704 shading units and 68 RT cores are tasked with rendering Fortnite's stylized graphics, which are not particularly demanding compared to photorealistic titles.

The GPU's clock speeds, with a base of 1440 MHz and a boost of 1710 MHz, are typical for the Ampere architecture and contribute to its 29.77 TFLOPS of FP32 performance. In Fortnite, this translates to high frame rates at lower resolutions, as evidenced by the 323.4 FPS at 1080p Low. The GPU's percentile rank of 80th places it ahead of a majority of tested graphics cards, and its average benchmark score of 35787 is closely matched by its nearest rivals, with all deltas within 1%.

The data shows that the GPU is the primary limiter at 4K and at higher quality presets. The frame rate drops from 323.4 FPS at 1080p Low to 107.9 FPS at 4K Low, a 67% reduction, which is consistent with the increase in pixel count. The GPU's 320W TDP and support for DirectX 12 Ultimate indicate that it is a high-power component designed for demanding workloads, but Fortnite's engine is not fully utilizing its ray tracing capabilities at the tested settings. The measured results show that the RTX 3080 is best paired with a 1440p monitor for this game, where it can deliver high refresh rates without hitting its memory or compute limits.
