Fortnite

The Intel Core i7-13700K paired with the NVIDIA GeForce RTX 5080 delivers a broad range of performance in Fortnite, scaling from an average of 448 FPS at 1080p Low down to 54 FPS at 4K Ultra. The data shows a system that is heavily CPU-limited at lower resolutions and settings, with the GPU becoming the dominant constraint only as resolution and visual complexity increase. This analysis breaks down the measured FPS results to interpret how each component contributes to the experience.

Resolution Scaling

The frame rate behavior across the three tested resolutions reveals the typical profile of a high-end gaming system in Fortnite. At 1080p with Low settings, the combo produces a staggering 448 FPS average, a figure that suggests the workload is far from saturating the RTX 5080. Moving to 1440p Low, the average drops to 285 FPS, a reduction of roughly 36%. At 4K Low, the average falls to 150 FPS, which is a 47% drop from the 1440p figure and a 67% drop from 1080p. This gradual reduction in frame rate as resolution increases is classic behavior when the CPU is the limiting factor; the GPU is not being fully utilized at the lower resolutions, so the performance does not scale down proportionally to pixel count.

The scaling pattern changes when we look at higher settings. With High settings, the frame rates are 245 FPS at 1080p, 155 FPS at 1440p, and 82 FPS at 4K. The drop from 1080p to 1440p is 37%, and from 1440p to 4K is 47%. The 4K High result is almost exactly one-third of the 1080p Low result, which shows that the GPU is now a more significant limiting factor. The most telling data point is the 4K Ultra result at 54 FPS, which is only 12% of the 1080p Low FPS. This shows a dramatic shift in the bottleneck: at low resolutions, the GPU has plenty of headroom, but at 4K Ultra, the GPU is fully saturated, and the processor is no longer the limiting factor. The 4K Medium result, at 106 FPS, is higher than the 4K High result of 82 FPS, which indicates that the Medium preset reduces GPU load enough to allow the CPU to feed the GPU more effectively.

The data shows that the combo is not limited by the CPU at 4K when settings are high. At 1080p, the GPU is idle for a significant portion of the time, but at 4K Ultra, the GPU is the clear bottleneck. This makes the system's behavior very scalable: the player can choose to favor high frame rates at 1080p or prioritize visual fidelity at 4K, with a correspondingly large FPS range.

CPU Role

The Intel Core i7-13700K is a 16-core, 24-thread desktop processor built on the Raptor Lake architecture. It has a base clock of 3.40 GHz and a boost clock of 5.40 GHz. It has an L3 cache of 30 MB shared, and it supports DDR4 and DDR5 memory. The CPU is unlocked, meaning it can be overclocked. In the benchmark database, this CPU has a 89th percentile ranking among all CPUs, with an average benchmark score of 46881. Its nearest rivals include the AMD Ryzen 9 5900, which scores 46971, a delta of -0.2%, and the AMD Ryzen 9 7845HX, which scores 46654, a delta of 0.5%. This puts the i7-13700K essentially on par with these high-end chips.

In Fortnite, this processor's role is most evident at lower resolutions. The 1080p Low result of 448 FPS indicates the CPU is capable of feeding the GPU far more frames than the GPU can render at higher settings. The processor has strong single-thread performance, as shown by a Geekbench single-core score of 2529 and a Cinebench R23 single-core score of 2116. This is important because Fortnite is known to be sensitive to single-thread performance. The multi-threaded performance is also strong, with a Cinebench R23 multi-core score of 30745. At 4K Ultra, the CPU is not the limiter, so the frame rate is determined by the GPU. The 3DMark 2-thread score of 2262 and the 3DMark 4-thread score of 4469 also show the CPU’s strength. The combination of high single-threaded and multi-threaded performance means the CPU can handle the game's logic at very high frame rates without becoming a constraint. The data does not show any signs of CPU throttling or frame instability, as the frame times are consistent across the Medium settings where min FPS data is available.

GPU Role

The NVIDIA GeForce RTX 5080 is a 16 GB GDDR7 GPU on the Blackwell 2.0 architecture, built on a 5 nm process at TSMC. It has a base clock of 2295 MHz and a boost clock of 2617 MHz. The memory is configured on a 256-bit bus and provides a bandwidth of 960.0 GB/s. The GPU has 10752 shading units and 84 RT cores. It has a launch MSRP of 999 USD. The GPU's benchmark scores are impressive, with a Passmark G3D score of 36565, a Geekbench Vulkan score of 255450, and a Geekbench OpenCL score of 235901. The GPU has an 87th percentile ranking among all GPUs, with an average benchmark score of 56083. Its nearest rivals include the AMD Radeon 8060S, which has a 0.6% higher score, and the AMD Radeon RX 9070 GRE, which has a 2.2% higher score.

In Fortnite, the GPU's role is most evident at 4K. At 4K Ultra, the combo produces 54 FPS, indicating the GPU is fully loaded. The 4K High setting yields 82 FPS, and the 4K Medium setting yields 106 FPS. The 4K Low setting yields 150 FPS. This is a clear demonstration of the GPU's scaling with visual load. The GPU's power is also shown in the 1440p High result of 155 FPS, and the 1080p High result of 245 FPS. The data indicates that the GPU is not the limiting factor at 1080p Low, where the 448 FPS is likely limited by the CPU. The memory bandwidth of 960.0 GB/s is a high number, but the 16 GB of GDDR7 on a 256-bit bus is sufficient for the game's requirements. The GPU has a boost clock of 2617 MHz, which is high, and helps to explain the strong performance in the high FPS ranges. The GPU is the bottleneck at 4K Ultra, where the frame rate drops to 54 FPS, and the GPU is clearly the limiting factor.
