Fortnite

Fortnite with the AMD Ryzen 5 7400F and Intel Arc B390 presents a challenging performance profile. The benchmark data indicates this pairing is positioned at the lower end of the spectrum for this title, with the GPU acting as the primary constraint across most configurations. The measured results show clear scaling patterns that define the playable envelope for this hardware combination, with the CPU demonstrating sufficient capability to drive the integrated graphics to its limits in lighter settings.

Settings Recommendations

The measured FPS data across different presets reveals a clear hierarchy of playability for the AMD Ryzen 5 7400F and Intel Arc B390 combination in Fortnite. At 1920x1080, the Low preset delivers an average of 115 FPS, which is the only configuration in the entire dataset that approaches high-refresh-rate territory. This represents a substantial jump over the Medium preset's 81 FPS average, indicating that the Low setting removes a significant bottleneck for the Arc B390's 1536 shading units. The High preset drops further to 63 FPS, while Ultra falls to 41 FPS, showing that each step up in visual fidelity exacts a heavy toll on this iGPU.

For 2560x1440, the Low preset still manages a respectable 73 FPS average, which is playable for most users, though the Medium preset drops to 51 FPS and High falls to 40 FPS. At 3840x2160, even the Low preset only achieves a 39 FPS average, which is marginal for a fast-paced Battle Royale title. The data suggests that the Low preset at 1080p is the optimal experience for this combo, as it is the only setting that provides a framerate high enough to keep up with the game's dynamic combat scenarios. The Medium preset at 1080p offers a compromise at 81 FPS, but the 34 FPS delta between Low and Medium indicates that the visual upgrade is not worth the performance penalty for competitive play.

The Ultra preset is effectively unusable across all resolutions, with the best case being 41 FPS at 1080p and a dismal 14 FPS at 4K. This pattern strongly suggests that users should prioritize framerate over fidelity with this hardware. The measured minimum FPS data for the Medium preset at 1080p shows a floor of 69 FPS, which is still within a playable range, but the average of 81 FPS means that intense build fights or busy endgame circles could cause noticeable stutter. The Low preset's lack of minimum FPS data in the pack suggests it maintains a more consistent frame delivery, reinforcing its status as the recommended choice for this combination.

GPU Role

The Intel Arc B390 is the decisive factor in this combo's Fortnite performance, and the data shows it is severely underpowered for this game. The GPU's benchmark score of 1482 in 3DMark Steel Nomad places it in the 9th percentile of all GPUs, a figure that aligns with its nearest rivals, which include the NVIDIA GeForce GT 520MX and GT 625 OEM, all within a 2.7% deltaPct of each other. This is an entry-level integrated graphics solution, and its performance in Fortnite reflects that positioning. The GPU's boost clock of 2500 MHz and base clock of 300 MHz are relevant, but the memory configuration is the more critical limitation; the system-shared memory with system-dependent bandwidth means the GPU is competing with the CPU for the same DDR5 resources. This is evident in the 4K results, where the High preset manages only 21 FPS and Ultra drops to 14 FPS, indicating that memory bandwidth starvation is likely compounding the raw compute limitations.

The Arc B390's architecture, Xe3-LPG on a 3 nm process, provides 7.680 TFLOPS of FP32 performance, but this is clearly insufficient for Fortnite's demands at higher settings. The pixel rate of 60.00 GPixel/s and texture rate of 120.0 GTexel/s are modest figures that translate directly to the framerate drops observed when transitioning from Low to Medium to High presets. At 1080p, the jump from Low (115 FPS) to Medium (81 FPS) represents a 34 FPS loss, and the jump to High (63 FPS) costs another 18 FPS. This scaling suggests that the GPU's 24 ROPs and 48 TMUs are quickly saturated as draw calls and texture complexity increase. The 12 RT cores are present but irrelevant for Fortnite, as the game's implementation of ray tracing is not a factor in these measured results.

The fact that the Arc B390 is an IGP with no dedicated VRAM and relies on system shared memory is a critical weakness. The measured data at 4K Ultra, which yields only 14 FPS, illustrates how the memory subsystem becomes a bottleneck at higher resolutions. Users should set expectations accordingly; this is not a GPU for high-fidelity gaming, and the benchmark results confirm that it is best suited for low-preset esports titles.

CPU Role

The AMD Ryzen 5 7400F is a vastly more capable component than the GPU it is paired with, and the data suggests it is not the limiting factor in Fortnite. The CPU's 6 cores and 12 threads based on Zen 4 architecture provide strong single-threaded performance, as evidenced by its Cinebench R23 single-core score of 3072. The boost clock of 4.70 GHz is high, and the 32 MB of shared L3 cache helps with game-level data locality. The CPU's percentile ranking of 83rd among all CPUs, with an average benchmark score of 32750, places it in a solid mid-range tier. Its nearest rivals include the Intel Core i5-14600T and AMD Ryzen 7 PRO 6850H, all within a 0.3% deltaPct of each other, indicating that the 7400F is competitive with those parts.

In Fortnite, the CPU's role is to feed the GPU with draw calls and physics calculations. Given that the Arc B390 is the bottleneck, the 7400F likely has headroom to spare. This is supported by the FPS scaling pattern: at 1080p Low, the combo achieves 115 FPS, which is still below the CPU's potential ceiling. The move from 1080p to 1440p at Low settings shows a 42 FPS drop (from 115 to 73 FPS), which is a GPU-side limitation, not a CPU one. If the CPU were the constraint, the framerate would remain constant across resolutions. The data shows a consistent decline as resolution increases, which is the classic signature of a GPU-bound scenario.

The CPU's memory bandwidth of 83.2 GB/s and dual-channel DDR5 support are adequate for feeding the iGPU, but the shared memory architecture means that the CPU and GPU are both accessing the same pool. The 7400F's Passmark multithread score of 25645 and single-thread score of 3689 indicate it can handle Fortnite's engine threads without issue. The 65W TDP and 5 nm process node mean it runs cool and efficient, but this is irrelevant to the gaming experience. The verdict is clear: the Ryzen 5 7400F is overqualified for this GPU, and users would see significant performance gains by pairing it with a discrete graphics card.

How This Combo Ranks

The combination of the AMD Ryzen 5 7400F and Intel Arc B390 ranks 3289 out of 3700 tested combos in Fortnite, placing it in the bottom 11% of all systems. This is a poor ranking that reflects the GPU's limitations rather than the CPU's capabilities. The rank is consistent with the GPU's individual 9th percentile standing, suggesting that the iGPU drags the entire system down to entry-level status. The data indicates that this combo is not suitable for Fortnite at any competitive level, as the framerates are too low to provide a smooth experience in most settings.

The ranking also highlights the mismatch between the components. The CPU's 83rd percentile ranking is in stark contrast to the GPU's 9th percentile, meaning that the system is severely unbalanced. The benchmark results show that the combo is 411 positions away from the middle of the pack, which is a significant gap. For context, the GPU's nearest rivals, such as the GeForce GT 710, would likely produce similar results, and the combo's ranking reflects that performance tier. Users with this setup should be aware that they are getting entry-level gaming performance, and the CPU is not the reason for the low rank.

Resolution Scaling

The FPS drop from 1080p to 4K is dramatic and reveals the limiting component clearly. At Low settings, the combo delivers 115 FPS at 1080p, 73 FPS at 1440p, and 39 FPS at 4K. This represents a 33% decrease from 1080p to 1440p and a 47% decrease from 1440p to 4K. The scaling is consistent with a GPU-bound scenario, where the rendering workload increases with pixel count, and the Arc B390's limited compute and memory bandwidth cannot keep up. The same pattern holds for High settings: 63 FPS at 1080p, 40 FPS at 1440p, and 21 FPS at 4K.

The percentage drops are steep, indicating that the GPU is overwhelmed as resolution increases. The fact that the CPU's performance does not change with resolution means that the 7400F is not a factor in these declines. For a CPU-bound system, the framerate would remain flat across resolutions, but this is clearly not the case. The data suggests that the Arc B390's system-shared memory is a major contributor to the poor scaling, as the memory bandwidth requirements at 4K exceed what the system can provide. Users should stick to 1080p to get playable framerates, as the 1440p results are borderline and 4K is only viable on Low settings with a 39 FPS average, which is still not ideal for a competitive shooter.

Measured FPS Breakdown

At 1920x1080, the data shows a clear progression across presets. Low settings deliver 115 FPS average, which is the highest score in the entire dataset. Medium settings drop to 81 FPS with a minimum of 69 FPS and a maximum of 93 FPS, indicating some variance in frame delivery. High settings yield 63 FPS, and Ultra settings fall to 41 FPS. The 74 FPS spread between Low and Ultra at 1080p is substantial, but the Low preset is the only one that approaches the 120Hz mark that competitive players often target.

At 2560x1440, the average framerates are 73 FPS for Low, 51 FPS for Medium (with a minimum of 44 FPS and maximum of 59 FPS), 40 FPS for High, and 26 FPS for Ultra. The Medium preset's minimum of 44 FPS is concerning for gameplay consistency, as it indicates the GPU can occasionally struggle to maintain a playable rate. The Low preset remains the only viable option at this resolution, with 73 FPS being sufficient for casual play but not ideal for high-level competition.

At 3840x2160, the results are grim. Low settings produce 39 FPS, Medium drops to 27 FPS (with a minimum of 23 FPS and maximum of 31 FPS), High manages only 21 FPS, and Ultra falls to 14 FPS. None of these framerates are acceptable for a Battle Royale game, where player movement and building require fast reaction times. The 4K Medium preset's minimum of 23 FPS is particularly problematic, as it suggests the system will experience noticeable hitches during intense moments. The Arc B390 is not capable of delivering a smooth Fortnite experience at 4K, and users should avoid this resolution entirely with this combo.
