Fortnite

Fortnite on the Intel Core Ultra 5 235 and NVIDIA GeForce RTX 4080 pairing shows a system that is overwhelmingly GPU-bound at higher resolutions, but transitions into a CPU-limited state at 1080p. The measured data reveals a clear hierarchy: the RTX 4080 is the dominant component for 4K and 1440p performance, while the Core Ultra 5 235’s 14-core/14-thread design becomes the bottleneck at lower resolutions where frame rates exceed 300 FPS. This analysis breaks down the exact FPS figures, component roles, and optimal settings based solely on the provided benchmark data.

Resolution Scaling

The progression from 1080p to 4K demonstrates a classic GPU workload curve, but with notable inflection points. At 1920x1080 with Low settings, the system delivers 432 avg FPS, which drops to 275 avg FPS at 2560x1440 (a 36% reduction) and further to 145 avg FPS at 3840x2160 (a 66% reduction from 1080p). This scaling pattern indicates that at 1080p Low, the CPU is the limiting factor—the GPU is not being fully utilized, as evidenced by the massive jump from 432 FPS at Low to 304 FPS at Medium (a 30% drop) suggesting the GPU is still not saturated.

The high-resolution data tells a different story. Moving from 1440p to 4K at High settings, the FPS drops from 150 to 79—a 47% decrease that closely mirrors the pixel count increase (from 3.7M to 8.3M pixels, a 2.25x jump that would theoretically halve FPS). This near-linear scaling confirms the RTX 4080 is the limiting factor at 4K. The Ultra preset at 4K yields only 52 avg FPS, which is the lowest measured result and shows the GPU struggling with the most demanding settings.

The Medium preset provides the only complete dataset with min/max FPS values, which helps illustrate variance. At 4K Medium, the system averages 102 FPS with a range of 87-118 FPS (a 31 FPS spread). At 1440p Medium, the average is 194 FPS with 165-223 FPS (a 58 FPS spread). At 1080p Medium, the average is 304 FPS with 259-350 FPS (a 91 FPS spread). The widening variance at lower resolutions further supports the CPU becoming the bottleneck—the Core Ultra 5 235's thread scheduling is creating frame pacing inconsistencies as it approaches its limits.

GPU Role

The NVIDIA GeForce RTX 4080 is the clear performance driver for Fortnite at resolutions above 1080p. With 16 GB of GDDR6X memory on a 256-bit bus delivering 716.8 GB/s bandwidth, the GPU has ample memory resources for Fortnite's textures and draw calls. The 2205 MHz base clock and 2505 MHz boost clock provide the raw compute throughput needed for the game's visual effects, and the data shows this hardware is well-matched to 1440p gaming.

The RTX 4080's benchmark scores place it in the 86th percentile of all GPUs, with an average benchmark score of 54247. Its nearest rival is the NVIDIA GeForce RTX 4080 SUPER, which scores 54209 (a 0.1% difference), meaning the standard 4080 is effectively identical in performance to its SUPER variant. The AMD Radeon Pro W5700X trails at 54828 (-1.1%), and the AMD Radeon RX 6750 GRE 12 GB scores 55698 (-2.6%), showing the RTX 4080 is competitive but not dominant in synthetic benchmarks.

In Fortnite specifically, the GPU's role becomes evident when comparing presets at 4K. The jump from Low (145 FPS) to Medium (102 FPS) is a 30% drop, and from Medium to High (79 FPS) is another 23% drop. This consistent degradation with each preset tier shows the GPU's rendering pipeline being progressively loaded with more shadows, post-processing, and geometry. The Ultra preset (52 FPS) halves the High preset's performance, indicating Fortnite's Ultra settings include features that disproportionately tax the Ada Lovelace architecture, likely related to ray tracing or advanced lighting that the RTX 4080's 76 RT Cores must handle.

CPU Role

The Intel Core Ultra 5 235 is a 14-core, 14-thread processor with a 3.40 GHz base clock and 5.00 GHz boost clock, using the Arrow Lake architecture on a 3 nm process. Its benchmark results show a balanced performer: the Cinebench R23 multicore score is 14769 and single-core is 2085, while PassMark scores include 37816 for multithread and 4516 for single thread. These numbers place it in the 89th percentile of all CPUs, with an average benchmark score of 46062.

The CPU's nearest rivals are remarkably close in synthetic performance. The AMD Ryzen AI 9 HX 375 scores 46030 (a 0.1% delta), the Intel Core i9-13900HX scores 46098 (-0.1%), and the AMD EPYC 4364P scores 45970 (0.2%). This clustering suggests the Core Ultra 5 235's 14 cores provide competitive multi-threaded performance, but its 14 threads (equal to cores, no hyper-threading) may limit certain workloads.

In Fortnite, the CPU's role is most apparent at 1080p Low where the system hits 432 FPS. This extreme frame rate requires the CPU to process game logic, physics, and draw calls at a rate that likely exceeds the Core Ultra 5 235's single-thread capacity. The fact that 1080p Medium (304 FPS) shows a 30% drop from Low, while 1440p Low (275 FPS) shows only a 9% drop from 1080p Low, indicates the CPU is saturated at 1080p regardless of GPU load. The 5.00 GHz boost clock provides decent single-thread performance, but the 14-thread configuration means only a fraction of cores are handling the game's main thread, creating a bottleneck that prevents the RTX 4080 from reaching its full potential at low resolutions.

Settings Recommendations

The measured data provides clear guidance for different display configurations. For 4K displays, the High preset (79 avg FPS) is the highest playable option, with Medium (102 avg FPS) offering a safer margin above 60 FPS. Ultra at 4K (52 avg FPS) should be avoided for competitive play, as it falls below the 60 FPS threshold and introduces responsiveness issues. Low at 4K (145 avg FPS) is overkill—the visual compromise doesn't justify the frame rate, since the game looks noticeably worse without the visual fidelity improvements.

For 1440p displays, the High preset (150 avg FPS) hits the sweet spot for high-refresh monitors, while Medium (194 avg FPS) is ideal for 165Hz panels. Low (275 avg FPS) is only useful for professional competitive players running 240Hz+ monitors who prioritize reaction time over visuals. Ultra (99 avg FPS) is playable but not optimal—the visual gains over High don't justify the 34% performance drop.

For 1080p displays, the Medium preset (304 avg FPS) is the recommended choice. It provides the best balance of visual quality and performance, with frame rates high enough for any current monitor. Low (432 avg FPS) is excessive for most users—the difference between 304 and 432 FPS is imperceptible on 240Hz displays but the visual downgrade is noticeable. High (236 avg FPS) is also viable, but Medium's higher frame rate and better frame pacing (as shown by the min/max data) make it the superior choice. Ultra (156 avg FPS) is not recommended at 1080p because the CPU bottleneck at this resolution means the extra GPU work doesn't translate to proportionally better visuals.
