Fortnite

Fortnite at 4K High on the Intel Core Ultra 5 235 and Intel Arc B580 pairing delivers an average of 37 FPS, which is below the 60 FPS target most players expect from a modern desktop setup. The data shows a clear and steep performance cliff as resolution increases, with the Ultra preset at 4K falling to just 24 FPS. This combination is best understood as a high-refresh-rate 1080p machine for this title, with the headroom to handle 1440p if you are willing to drop settings to Low or Medium.

Resolution Scaling

The measured FPS data illustrates how dramatically the load shifts from the CPU to the GPU as resolution climbs. At 1080p Low, the system produces 200 FPS, which indicates that the CPU is feeding the GPU effectively at lower resolutions. Moving to 1440p Low, the average drops to 127 FPS, a 36.5% reduction, and at 4K Low it falls further to 67 FPS, which is a 47.2% reduction from the 1440p figure. This scaling pattern suggests that the Arc B580 is the limiting factor as pixel count increases, a typical situation for a mid-range GPU.

The scaling becomes more punishing at higher quality presets. At High settings, the transition from 1080p (109 FPS) to 1440p (69 FPS) represents a 36.7% loss, and the jump to 4K (37 FPS) is a 46.4% loss from 1440p. The Ultra preset shows the most severe drop-off: 72 FPS at 1080p, 46 FPS at 1440p, and 24 FPS at 4K. The difference between 1440p High and 4K High is a 32 FPS gap, which is larger than the gap between 1080p High and 1440p High (40 FPS). This indicates that the GPU is running out of raw throughput and memory bandwidth at 4K, particularly with the more demanding settings.

The data indicates that the CPU is not the primary bottleneck at higher resolutions. While the Core Ultra 5 235 has a boost clock of 5.00 GHz and 14 cores, the consistent FPS drops across all settings when moving from 1440p to 4K point directly at the GPU's limits. For example, at 1080p Medium, the system hits 141 FPS, but at 1440p Medium it drops to 89 FPS, and at 4K Medium it reaches only 47 FPS. The scaling factor from 1080p to 1440p is 0.63, and from 1440p to 4K is 0.53, showing that the performance penalty is not linear and the GPU struggles more as resolution increases.

Settings Recommendations

For players prioritizing a smooth competitive experience on a 1080p display, the Low preset at 200 FPS is the clear choice, as it provides the highest headroom for high-refresh-rate monitors. The Medium preset at 141 FPS is a strong alternative for those who want better visual fidelity without sacrificing too much responsiveness, and the data shows it maintains a 120 FPS minimum, which is still above the 100 FPS threshold many players consider playable. High at 109 FPS is acceptable for 60Hz displays, but it is a significant drop from Medium, making Medium the sweet spot for 1080p.

At 1440p, the recommendation shifts based on display refresh rate. The Low preset at 127 FPS is the only setting that clears the 120 FPS mark, making it the go-to for 120Hz+ panels. Medium at 89 FPS is a balanced choice for 60-100Hz monitors, offering a solid visual upgrade over Low with a 76 FPS minimum that stays above typical VSync thresholds. High at 69 FPS is playable on a 60Hz screen but leaves little margin for drops in busy scenes, and Ultra at 46 FPS is not recommended for anything other than screenshot-style play.

The 4K data is straightforward: this pairing is not suited for 4K Fortnite. Even Low at 67 FPS is marginal, and the Medium preset at 47 FPS with a 40 FPS minimum will feel stuttery. High at 37 FPS and Ultra at 24 FPS are below playable thresholds for a shooter. The benchmark results indicate that 4K should be avoided unless the player is willing to accept a significant performance compromise, and even then, the experience will be suboptimal.

GPU Role

The Intel Arc B580 is the decisive component in this pairing's gaming performance, and the data shows its limitations clearly. With 12 GB of GDDR6 memory on a 192-bit bus and 456.0 GB/s of bandwidth, the card has enough memory capacity for high-resolution textures, but the throughput is not sufficient to maintain high frame rates at 4K with demanding settings. The base and boost clock are both locked at 2670 MHz, which is a modest frequency for a modern GPU, and the 13.67 TFLOPS of FP32 compute is a mid-range figure.

The GPU's benchmark scores place it in the 68th percentile of all GPUs, with an average benchmark score of 23021. Its nearest rivals in the database include the NVIDIA GeForce RTX 2080, which it trails by 0.6%, and the NVIDIA GeForce RTX 3080, which it trails by 0.7%. This puts the Arc B580 in the performance class of older high-end cards, but not the current generation of top-tier hardware. The 3DMark Steel Nomad DX12 score of 3068 and the Geekbench Vulkan score of 109672 reflect a card that is capable in modern APIs, but the passmark DirectX 11 score of 128 and DirectX 12 score of 76 suggest that legacy API performance is not a strength.

The memory configuration is interesting for this game. The 12 GB capacity is more than enough for Fortnite's textures, even at 4K Ultra, so the card is not running out of VRAM. The bottleneck is the memory bandwidth of 456.0 GB/s, which is insufficient to feed the shading units at high resolutions and settings. The data shows that at 4K Ultra, the card produces only 24 FPS, which is a clear sign that the GPU is compute and bandwidth limited, not capacity limited. The 20 RT cores are present for ray tracing, but Fortnite's standard rasterization performance is the primary concern here, and the card's results are in line with its synthetic benchmarks.

Q: Is the CPU or GPU the bottleneck in this pairing?

A: The benchmark results indicate the GPU is the limiting factor at higher resolutions. The FPS drops significantly from 1080p to 1440p and again to 4K, which is a classic sign of GPU saturation, while the CPU's performance is sufficient to feed the GPU at lower resolutions.

CPU Role

The Intel Core Ultra 5 235 provides a solid foundation for this gaming configuration, but its role shifts depending on the resolution and settings. With 14 cores and 14 threads, it has a high core count for a mainstream desktop processor, and its boost clock of 5.00 GHz ensures strong single-thread performance, which is critical for Fortnite's game logic and physics. The benchmark scores reflect this: a Cinebench R23 single-core score of 2085 and a Passmark single-thread score of 4516 are competitive figures.

The CPU's multi-threaded performance is also robust, as shown by a Cinebench R23 multi-core score of 14769 and a Passmark multithread score of 37816. These numbers place the CPU in the 89th percentile of all CPUs, with an average benchmark score of 46062. Its nearest rivals include the AMD Ryzen AI 9 HX 375, which it matches within 0.1%, and the Intel Core i9-13900HX, which it trails by 0.1%. This indicates that the processor is not a weak link in the system.

The data shows that the CPU is only a bottleneck at very high frame rates and low resolutions. At 1080p Low, the system reaches 200 FPS, which is near the practical limit for many game engines and indicates that the CPU is working hard. However, the FPS does not increase beyond this point, suggesting that the CPU's single-thread performance is the limiting factor at this extreme. At 1080p Medium, the FPS drops to 141, and at High to 109, which shows that the GPU is taking over the workload as settings increase.

The CPU's memory support includes DDR5 on a dual-channel bus with 102.4 GB/s of bandwidth, which is adequate for feeding the 14 cores. The 24 MB of shared L3 cache is a modest amount, but it is sufficient for gaming workloads. The integrated Arc Xe-LPG Graphics 24EU is present but not relevant for gaming with a discrete GPU installed. The TDP of 65 watts is low, which means the CPU will not generate excessive heat, allowing for a capable air cooler to suffice.

Measured FPS Breakdown

The measured FPS data provides a complete picture of this system's performance in Fortnite. At 1920x1080, the Low preset achieves an average of 200 FPS, which is the highest score recorded. The Medium preset produces an average of 141 FPS with a minimum of 120 FPS and a maximum of 162 FPS, showing a stable frame time. The High preset delivers 109 FPS, and the Ultra preset drops to 72 FPS. The scaling from Low to Ultra at this resolution is a 64% performance loss, which is significant but still leaves the system playable at all settings.

At 2560x1440, the performance drops are more pronounced. The Low preset averages 127 FPS, which is a 36.5% decrease from 1080p Low. The Medium preset averages 89 FPS with a minimum of 76 FPS and a maximum of 103 FPS, representing a 36.9% decrease from its 1080p counterpart. The High preset averages 69 FPS, a 36.7% drop, and the Ultra preset averages 46 FPS, a 36.1% drop. The consistency of the percentage drops across settings at this resolution indicates that the GPU is scaling uniformly with pixel count.

At 3840x2160, the system struggles to maintain playable frame rates. The Low preset averages 67 FPS, which is a 47.2% decrease from 1440p Low. The Medium preset averages 47 FPS with a minimum of 40 FPS and a maximum of 54 FPS, showing significant frame time variance. The High preset averages 37 FPS, a 46.4% drop from 1440p High, and the Ultra preset averages 24 FPS, a 47.8% drop. The data shows that the GPU's performance degrades at a faster rate when moving from 1440p to 4K than from 1080p to 1440p, indicating that the memory bandwidth and compute resources are being exhausted.

The combo rank in the database is 2032 out of 2740 combinations for this game, which places this pairing in the lower-middle range for Fortnite performance. This ranking is influenced by the GPU's limitations at higher resolutions, despite the CPU's strong showing. The data suggests that this system is best utilized at 1080p with Medium or High settings for a balanced experience, or at 1440p with Low settings for competitive play. The 4K results are uniformly poor and should not be a target for this hardware configuration.
