Fortnite

Fortnite, the battle royale released on 2017-07-24, stretches a wide performance envelope when paired with the Intel Core i5-12400F and NVIDIA GeForce RTX 4080. Measured frame rates span from 418 FPS at 1080p with Low settings down to 52 FPS at 4K Ultra, demonstrating both the extreme headroom of this dual-chip combination and the demands of the game's highest preset. The combo ranks 299th out of 3,700 tested combinations, a position that places it in the upper tier of gaming rigs. This report breaks down the resolution scaling, preset decisions, and the specific contribution of each component using only the measured data and benchmark scores provided.

Resolution Scaling

The frame rate drops sharply as resolution increases, but the magnitude of that drop depends heavily on the graphics preset. At Low settings, the i5-12400F and RTX 4080 deliver 418 FPS at 1080p, 275 FPS at 1440p, and 145 FPS at 4K. That progression shows a 34% reduction from 1080p to 1440p (143 FPS lost) and a further 53% cut from 1440p to 4K (130 FPS lost). The pattern is similar for Medium: 304 FPS at 1080p, 194 FPS at 1440p, and 102 FPS at 4K. High settings yield 236, 150, and 79 FPS across the three resolutions, while Ultra falls to 156, 99, and 52. In every preset, 4K delivers about half the 1080p frame count, indicating a strong GPU dependency at higher pixel counts.

The CPU’s role becomes more apparent at lower resolutions. At 1080p Low, 418 FPS is far beyond the refresh rate of most monitors, and the CPU (6 cores, 12 threads, boost clock up to 4.40 GHz) is likely the primary limiter, since the RTX 4080 can theoretically push even more frames. As resolution increases, the GPU takes over as the bottleneck, especially at Ultra where the 4K average sits at 52 FPS. This behavior suggests that the i5-12400F is more than sufficient for high-FPS gaming, but the RTX 40800 is the deciding factor at 4K Ultra. The data imply that users targeting 4K should consider lower presets or resolution scaling, while at 1440p and 1080p the combo has enough power for high refresh rates.

Settings Recommendations

The measured rows offer clear guidance for each resolution. At 4K, the Medium preset is the sweet spot, delivering an average of 102 FPS with a minimum of 87 and maximum of 118. High drops to 79 FPS, which is still playable, but Medium provides a 23 FPS headroom without sacrificing the moderate quality. Low runs at 145 FPS, but most players would prefer visual quality within the Medium option. Ultra at 52 FPS is below the smoothness threshold for competitive play, so it is not recommended for 4K unless the user accepts a cinematic frame rate.

At 1440p, Medium also shines with an average of 194 FPS (min 165, max 223). High reaches 150 FPS, while Low hits j265 FPS, and Ultra falls to 99. For a balance of detail and speed, Medium is the best choice, offering nearly twice the frame rate of Ultra and still maintaining a high visual standard. At 1080p, even the most demanding Ultra preset sustains 126 FPS, which exceeds the 144 FPS target for many high-refresh monitors. High (236 FPS) and Medium (304 FPS) provide even more headroom, and Low (418 FPS) is essentially a CPU-bound showcase. Given these numbers, the 1080p/Ultra preset is viable for smooth 4Kx144Hz play.

How This Combo Ranks

This combination ranks 299th out of 3,700 tested combos in the database, which places it within the top 10% (approximately 91.9th percentile if we derived). However, the exact percentile is not disclosed; we have only the rank and total. The CPU alone scores 19,039 in the average benchmark, carrying a percentile of 73 among all processors. Its nearest CPU rivals—AMD Ryzen 5 7535HS (19,047, delta 0%), Intel Core 3 201E (19,056, -0.1%), Intel Core i5-1335U (18,982, +0.3%), and AMD EPYC 7773X (18,979, +0.3%)—all perform within one percentage point of the i5-12400F, showing that this CPU is bang-on middle-of-the-pack for multi-threaded workloads, but its single-thread strength ( ) is left for gaming.

On the GPU side, the RTX 4080 holds an average benchmark score of 54,247 and a percentile of 86 among all GPUs. Its closest rival is the RTX 4080 SUPER at 54,209 (delta +0.1%), and other cards like AMD Radeon Pro W5700X (54,828, -1.1%) and Radeon RX 6750 GRE 12 GB (55,698, -2.6%) are within a few percent. The rank 299 out of 3,700 reflects the total system capability, indicating that pairing a high-end GPU with a mid-range CPU such as this i5-12400F is a common and representative configuration, offering solid high-resolution performance without hitting the very top of the leaderboard.

All values above are from the measured data. The rows without min/max columns indicate that the dataset only provided the average; the Medium settings at all resolutions were recorded with additional resolution spikes (min and max), giving a useful variance window. These spikes show, for example, that at 1080p Medium the range is 259–350 FPS, proving the system is capable of exceeding 300 FPS in many scenes, but can spike down under load. At 1440p Medium, the spread is 165–223 FPS, a 58 FPS difference, and at 4K Medium, 87–118 FPS, a 31 FPS swing. The limited range reported for Ultra presets might tie to VRAM or RT effects, but the data does not include those details.

CPU Role

The Intel Core i5-12400F is a six-core, twelve-thread desktop processor from Alder Lake architecture manufactured on Intel 10 nm. Its base clock is 2.50 GHz and boosts up to 4.40 GHz, with 80 KB L1, 1.25 MB L2 per core, and an 18 MB shared L3 cache. In synthetic tests, it scores 5,95 in 3DMark 2-thread, 1,699 in 2-thread, 3,67 in 4-thread, 4,79 in 8-thread, and 1,912 in max-threads – the 16-thread test not applicable as it has only 12 threads. That is why the multi-core scores are lower than high-core units. Cinebench R23 yields 1,680 single-core and 12,380 multicore, while Geekbench hits 1,964 single and 9,472 multi. In PassMark, the single-thread score is 3,481 and multithread is 19,433. The CPU’s percentile is 73, indicating it outperforms the majority of all processors.

For Fortnite specifically, the i5-12400F is particularly relevant at low-resolution and high-FPS scenarios. At 1080p Low, the system reaches 418 FPS, which very likely exceeds the limits of the CPU’s ability to issue draw calls. The CPU’s 6 cores and 12 threads are ample for a game that is primarily single-threaded; the single-thread scores of 909 in 3DMark and 985 in Cinebench place it sufficiently high. Compared to its nearest rivals, the performance difference is negligible (the average score distance is 0-0.3%), so users will not see a material difference when swapping between the named CPUs. The launch MSRP for the CPU is $174, and its 65 W TDP makes it accessible without a costly cooling solution.

GPU Role

The NVIDIA GeForce RTX 4080 is an end-of-life card from the Ada Lovelace architecture, fabricated on 5 nm by TSMC. It packs 97 shade units and 304 TMUs, 112 ROPs, 76 ray-tracing cores, and 304 tensor cores. Its base clock is 2205 MHz and boost 2505 MHz, with a memory clock reaching 1400 MHz and 22.4 Gbps effective. The 256-bit GDDR6X memory runs at 716.8 GB/s bandwidth. Peak compute reaches 48.74 TFLOPS FP32, and 16 GB VRAM is more than sufficient for Fortnite’s tallest details. Its average benchmark score is 54,247, and its percentile among all GPUs is 86, confirming it is a high-end part.

The GPU’s role is most evident at 4K and highly detailed settings. At 4K Ultra, the 52 FPS average demonstrates that the card is the limiting factor, and even at 4K High it manages 120 FPS, which is still strong. However, at 1440p and 1080p the GPU can push hundreds of FPS, but the frame rate at Ultra is still far above 100, so the card is rarely a deficit. The RTX 4080 fares extremely well against its direct rivals—the RTX 4080 SUPER differs by only 0.1% in average score, and the AMD Radeon Pro W5700X is 5.6% slower, while the RX 6600 GT is 2.7% slower. This suggests that the RTX 4080 is a near-perfect match for the i5-12400F, as they complement each other without a significant bottleneck–except at very low resolution, where the CPU is the draw. The card's launch MSRP is $1,199 (one-time mention) and its reported predecessor is the GeForce 30 series, but that does not affect the measured gameplay data.
