Fortnite

Fortnite on the Intel Core Ultra 7 265 and NVIDIA GeForce RTX 4080 combination produces a wide spread of frame rates that scale predictably with both resolution and quality preset. The measured data shows a system capable of high refresh rate play at 1080p and 1440p, while 4K remains playable but demands careful settings selection. This analysis walks through the measured FPS rows, the CPU and GPU contributions, and how this specific pairing ranks among all tested combinations.

Resolution Scaling

The transition from 1920x1080 to 3840x2160 reveals a substantial performance cost that grows as the quality preset increases. At Low settings, the average frame rate drops from 432 FPS at 1080p to 275 FPS at 1440p, a reduction of 157 FPS, and then further down to 145 FPS at 4K, another 130 FPS drop. The scaling from 1080p to 4K at Low settings represents a 66% reduction in average FPS, which is characteristic of a GPU-bound scenario where pixel count dominates the workload.

Moving to Medium settings, the same resolution progression shows 304 FPS at 1080p, 194 FPS at 1440p, and 102 FPS at 4K. The percentage drops between each step are consistent, with 1440p delivering 64% of the 1080p performance and 4K delivering 53% of the 1440p performance. This pattern indicates that the RTX 4080 is the primary limiter as resolution increases, with the CPU maintaining sufficient headroom to feed the GPU at lower resolutions.

High settings present a similar trend with 236 FPS at 1080p, 150 FPS at 1440p, and 79 FPS at 4K. The 4K result at High settings falls below the 80 FPS threshold that many users consider minimum for smooth gameplay, but remains playable with adaptive sync. The Ultra preset shows the most dramatic scaling, dropping from 156 FPS at 1080p to 99 FPS at 1440p and finally 52 FPS at 4K. That 4K Ultra result is the only measured configuration that dips below 60 FPS, suggesting the combination of maximum pixel count and maximum settings overwhelms the GPU.

The scaling behavior across all presets points to a system where the RTX 4080 becomes the bottleneck as resolution increases, while the Core Ultra 7 265 provides enough throughput to avoid limiting at 1080p and 1440p. At 4K, the frame rate differences between Low and Ultra become more pronounced, with the 145 FPS Low result versus 52 FPS Ultra representing a 2.8x spread, which is larger than the spread at 1080p where Low achieves 432 FPS versus Ultra at 156 FPS, a 2.8x difference as well. This consistency suggests the GPU scaling with settings is uniform across resolutions.

CPU Role

The Intel Core Ultra 7 265 brings 20 cores and 20 threads to this pairing, with a base clock of 2.40 GHz and a boost clock of 5.30 GHz. The architecture, Arrow Lake-S, uses a 3 nm process from TSMC with 17,800 million transistors on a 243 mm² die. The cache hierarchy includes 192 KB of L1 per core, 3 MB of L2 per core, and 30 MB of shared L3 cache. These specifications position the CPU as a high-core-count desktop part that excels in threaded workloads, which is reflected in its Cinebench R23 multicore score of 42216 and single-core score of 5960.

In Fortnite, the game's engine typically scales with a limited number of threads, making single-core performance and memory latency more relevant than raw core count. The 5.30 GHz boost clock provides strong single-thread performance, as evidenced by the PassMark single-thread score of 4689 and Cinebench R23 single-core result of 5960. The 20 cores ensure that background tasks and the game's auxiliary threads do not interfere with the main rendering threads, which is important for maintaining consistent frame pacing.

The data indicates the CPU is not the limiting factor at 1080p, where the RTX 4080 produces 432 FPS at Low settings and 236 FPS at High settings. These frame rates are high enough that even a capable GPU would struggle to exceed them without a matching CPU, but the Core Ultra 7 265's boost clock keeps the system ahead of the GPU's output. At 4K, the CPU's role diminishes further as the GPU becomes the clear bottleneck, with the measured FPS at High settings (79 FPS) being roughly one-third of the 1080p High result (236 FPS).

The CPU's memory bandwidth of 102.4 GB/s over a dual-channel DDR5 interface is sufficient for this workload, and the 30 MB of L3 cache helps keep frequently accessed game data close to the cores. The PassMark multithread score of 49682 and integer math score of 134773 indicate strong overall processing capability, but in Fortnite, the single-thread performance is the more critical metric, and the 5.30 GHz boost clock delivers accordingly.

Settings Recommendations

The measured FPS rows provide clear guidance for optimizing the experience across different display refresh rates. For 1080p displays with 240 Hz refresh, the High preset at 236 FPS is the recommended choice, as it stays above the refresh rate while leaving headroom for occasional dips. The Medium preset at 304 FPS exceeds 240 Hz comfortably but the visual quality reduction may not be worth the extra frame rate. The Ultra preset at 156 FPS is acceptable for 144 Hz displays but falls short of 240 Hz, making High the better balance.

For 1440p at 144 Hz, the High preset delivers 150 FPS, which sits just above the refresh rate and provides a smooth experience. The Medium preset at 194 FPS is also viable and offers more headroom for demanding scenes, but the step up to High at 150 FPS is the minimum recommended for competitive play. The Ultra preset at 99 FPS is below 144 Hz and would result in screen tearing without VRR, so it is only recommended for slower-paced gameplay or when visual fidelity takes priority.

For 4K at 60 Hz, the Medium preset at 102 FPS is the best experience, as it exceeds the 60 Hz refresh rate with room to spare. The Low preset at 145 FPS is overkill for a 60 Hz display and sacrifices visual quality unnecessarily. The High preset at 79 FPS is playable but may dip below 60 FPS in heavy scenes, making Medium the safer choice. The Ultra preset at 52 FPS falls below 60 Hz and is not recommended for smooth gameplay.

The data shows that the Medium preset offers the most consistent performance across all resolutions, with the only measured minimum FPS values (87 at 4K, 165 at 1440p, 259 at 1080p) appearing in this preset. This suggests Medium provides a stable frame time distribution, making it the safest default recommendation for users who prioritize consistency over absolute visual quality.
