Fortnite

Fortnite on the Intel Core i7-14700K paired with the Intel Arc B390 presents a stark study in bottleneck dynamics. The CPU is a high-end desktop part sitting in the 94th percentile of all processors, while the GPU is an integrated solution that ranks in the 9th percentile of all graphics cards. The measured frame rates across resolutions and settings tell a clear story: this is a system where the graphics processor is the definitive limiting factor, and the substantial processing headroom of the i7-14700K is largely left untapped in this title.

Resolution Scaling

The data shows a predictable yet severe collapse in performance as resolution increases, confirming that the Intel Arc B390 is the primary constraint. At 1080p with Low settings, the combo produces an average of 115 FPS. Moving to 1440p at the same preset drops the average to 73 FPS, a reduction of roughly 36.5%. The jump to 4K at Low settings further crushes performance down to 39 FPS, which is just a third of the 1080p figure. This pattern indicates that the GPU is being saturated at even the lowest fidelity settings, leaving little room for the resolution to scale without catastrophic frame loss.

The scaling behavior is consistent across all settings presets. With High settings, the average frame rate falls from 63 FPS at 1080p to 40 FPS at 1440p, and then to 21 FPS at 4K. This is a roughly 67% drop from 1080p to 4K. The Medium preset shows the same trend, with averages of 81 FPS at 1080p, 51 FPS at 1440p, and 27 FPS at 4K. The Ultra preset is the most demanding, yielding only 41 FPS at 1080p, which plummets to 26 FPS at 1440p and a practically unplayable 14 FPS at 4K.

These numbers suggest that the performance curve is largely linear with pixel count, indicating that the system is not hitting a memory bandwidth or CPU limitation wall, but rather the raw shading and fill-rate capabilities of the Arc B390. The delta between 1080p and 1440p is consistently a factor of roughly 0.6, and the delta between 1440p and 4K is another factor of 0.5. This consistent scaling implies that the Intel Core i7-14700K is delivering frames to the GPU fast enough, but the GPU simply cannot process them any faster as the pixel workload increases. The i7-14700K’s 20 cores and 28 threads, capable of a 33440.5 score in Cinebench R23 multi-core, are not the bottleneck; the data indicates that the Arc B390's 7.680 TFLOPS FP32 compute is the ceiling.

GPU Role

The Intel Arc B390 is an integrated graphics processor (IGP) built on the Xe3-LPG architecture with a 3 nm process node. Its role in this pairing is to render frames, and the benchmark results show it is overwhelmed by Fortnite's demands at higher resolutions. The GPU's memory configuration is "System Shared," meaning it relies on the system's main memory rather than dedicated VRAM. This architecture is a key factor in its performance profile, as the bandwidth is described as "System Dependent." This shared memory arrangement often leads to performance penalties, particularly at higher resolutions where memory pressure increases.

The Arc B390's clock speeds are listed with a base of 300 MHz and a boost of 2500 MHz. While the boost clock is relatively high, the GPU's modest specifications—1536 shading units, 48 TMUs, and 24 ROPs—limit its throughput. The pixel rate is 60.00 GPixel/s, and the texture rate is 120.0 GTexel/s. These figures are low for modern gaming, and the measured FPS reflects this. For instance, at 4K Ultra, the average FPS is just 14, which is below the minimum threshold for a playable experience. Even at 1080p Low, the 115 FPS average is respectable, but the lack of dedicated VRAM could cause hitches in more complex scenes, although the provided data does not show min FPS for that setting.

The GPU's DirectX 12 Ultimate support (12_2) means it is feature-compatible with modern titles, but its raw compute power is insufficient for high-fidelity gaming. The 3DMark Steel Nomad DX12 score of 1482 places it in the 9th percentile of all GPUs, and its nearest rivals include legacy parts like the NVIDIA GeForce GT 710 and GT 625 OEM. This positioning is evident in the Fortnite results, where even the High preset at 1080p yields only 63 FPS. The data suggests that the Arc B390 is more suited for esports-level settings at low resolutions than for demanding visual fidelity, and the Core i7-14700K's capabilities are entirely secondary to this GPU limitation.

How This Combo Ranks

In the grand database of tested combinations, this specific pairing of the Intel Core i7-14700K and Intel Arc B390 ranks 2417 out of 2740 combos for Fortnite. This places it in the bottom 12% of all configurations, a position that is heavily influenced by the GPU's low percentile ranking. The combo's rank is a direct consequence of the Arc B390's performance, which is in the 9th percentile of all GPUs, rather than the CPU, which is in the 94th percentile of all CPUs.

The disparity between the components is stark. While the CPU's nearest rivals include the AMD Ryzen 9 7950X and AMD Ryzen 9 7940HX, with performance deltas of -0.2% and -0.7% respectively, the GPU's nearest rivals are the NVIDIA GeForce GT 520MX and NVIDIA GeForce 800M. This indicates that the CPU is competing at the highest tier, while the GPU is competing with entry-level mobile parts from over a decade ago. The combo's overall rank of 2417 suggests that for Fortnite, this pairing is not a balanced one. The data implies that a much weaker CPU paired with a stronger discrete GPU would likely achieve a higher rank, as the i7-14700K's processing power is largely irrelevant when the GPU is the limiting factor.

The benchmark results show that the combo's performance is entirely GPU-bound. The average FPS at 1080p Low is 115, which is a decent result, but it falls off a cliff as the resolution increases. This is not a sign of a well-balanced system; rather, it highlights the extreme bottleneck created by the integrated GPU. The data positions this combo as one for basic play or as a reference point for how a powerful CPU cannot compensate for a weak GPU in a modern game like Fortnite.

Measured FPS Breakdown

The measured FPS data provides a complete picture of the combo's performance across twelve distinct configurations. At 1080p, the results show a wide spread based on settings. The Low preset delivers an average of 115 FPS, which is the highest score recorded for this combo. The Medium preset yields an average of 81 FPS, with a minimum of 69 FPS and a maximum of 93 FPS. The High preset drops to an average of 63 FPS, and the Ultra preset falls to an average of 41 FPS. This shows that even at the lowest resolution, the Ultra preset is only playable at a modest frame rate.

At 1440p, the performance is noticeably lower. The Low preset averages 73 FPS, while the Medium preset averages 51 FPS, with a minimum of 44 FPS and a maximum of 59 FPS. The High preset averages 40 FPS, and the Ultra preset averages 26 FPS. These numbers indicate that 1440p gaming with this combo is only viable on the Low preset, as the Medium preset's minimum of 44 FPS might feel inconsistent to some players.

At 4K, the results are largely unplayable. The Low preset averages 39 FPS, the Medium preset averages 27 FPS with a minimum of 23 FPS and a maximum of 31 FPS, the High preset averages 21 FPS, and the Ultra preset averages a mere 14 FPS. The data clearly shows that 4K is not a target resolution for this hardware pairing. The Medium preset at 4K has a min FPS of 23, which indicates severe stuttering potential. The combination of the CPU and GPU is simply not equipped for high-resolution gaming, as the Arc B390's shared memory and low compute power cannot handle the pixel workload.

Settings Recommendations

Based on the measured FPS data, the optimal settings for this combo depend entirely on the target resolution and desired smoothness. For a 1080p display, the Low preset is the only configuration that provides a consistently high frame rate, averaging 115 FPS. This is the best choice for competitive play where high refresh rates are beneficial. The Medium preset at 1080p offers a reasonable 81 FPS average, with a minimum of 69 FPS, which is still playable and provides better visual quality. The High preset at 1080p, with an average of 63 FPS, is acceptable for a slower-paced experience, but the Ultra preset at 41 FPS is not recommended for smooth gameplay.

For 1440p, the Low preset is the only setting that achieves a comfortable average frame rate, at 73 FPS. The Medium preset at 1440p, with an average of 51 FPS and a minimum of 44 FPS, is borderline; it may be acceptable for users who prioritize visual fidelity over smoothness, but the frame dips could be noticeable. The High and Ultra presets at 1440p, averaging 40 FPS and 26 FPS respectively, are not recommended for a playable experience.

At 4K, no preset provides a consistently playable experience. The Low preset averages 39 FPS, which is below the threshold for smooth gameplay, and the Medium preset's minimum of 23 FPS confirms significant stuttering. The data suggests that users should avoid 4K with this hardware. The most balanced recommendation is to use the Low preset at 1080p for the highest frame rates, or the Medium preset at 1080p if visual quality is more important than maximum FPS. The Ultra preset should be avoided entirely, as it only yields a playable frame rate at no tested resolution.
