GPU Role

The Intel Arc B390 is unequivocally the performance anchor for this system. Its synthetic benchmark score of 1482 in 3DMark Steel Nomad DX12 places it in the 9th percentile of all GPUs, a position that firmly establishes it as entry-level hardware. The nearest rivals in the data, the NVIDIA GeForce GT 520MX and GeForce 800M, are ancient mobile parts, and the Arc B390 is only 1.3% and 1.5% faster, respectively. This context is crucial; the Arc B390 is not just a low-end card, it is operating in a performance tier that is decades old.

The GPU's architecture is Xe3-LPG, built on Intel's 3 nm process. It features 1536 shading units, 48 texture mapping units, and 24 raster output pipelines. The boost clock is rated at 2500 MHz, with a base clock of 300 MHz. Critically, the memory configuration is "System Shared," meaning the GPU has no dedicated VRAM of its own. The memory bandwidth is listed as "System Dependent," which means its performance is tied directly to the speed of the system's main RAM. This is a significant handicap for a game like Fortnite, which can be sensitive to memory bandwidth.

The impact of this GPU is clearly visible in the measured FPS data. The frame rate is heavily influenced by resolution and settings, which is a classic sign of a GPU-bound scenario. At 1920x1080 with Low settings, the system averages 115 FPS. This is a playable frame rate, but it is the peak of its performance. Moving to 2560x1440 drops the average to 73 FPS at Low settings, and at 3840x2160, the average plummets to 39 FPS. This scaling shows that the GPU's compute and memory resources are quickly exhausted as the pixel count increases.

The GPU's pixel rate is rated at 60.00 GPixel/s and its texture rate at 120.0 GTexel/s. While these figures are not directly comparable to rival specs in the pack, they provide a baseline for its fill-rate capabilities. The FP32 performance is 7.680 TFLOPS. In practice, these specifications translate to a card that can handle competitive gaming at low resolutions and settings, but it struggles under the load of higher detail levels. The 14 FPS average at 4K Ultra confirms how quickly the GPU's limited resources are overwhelmed.

CPU Role

In stark contrast to the GPU, the AMD Ryzen 9 9900X3D is a high-end desktop processor. It is a 12-core, 24-thread part based on the Zen 5 architecture (Granite Ridge), built on TSMC's 4 nm process. It is in the 91st percentile of all CPUs, with an average benchmark score of 54762. The data shows it is a formidable processor, with its closest rival, the Intel Core Ultra 5 245KF, being only 0.6% faster. This places the 9900X3D in a performance bracket that is entirely wasted in this configuration.

The CPU's specifications are impressive. It has a base clock of 4.40 GHz and a boost clock of 5.50 GHz. It features a massive 128 MB of L3 cache, which is a hallmark of the X3D line and is particularly beneficial for gaming. It supports DDR5 memory on a dual-channel bus, with a memory bandwidth of 89.6 GB/s. The processor's TDP is rated at 120 W. In synthetic benchmarks, it scores 47737 in Cinebench R23 multi-core and 6739 in single-core, demonstrating its immense compute power.

However, in Fortnite, this power is largely irrelevant. The measured FPS data shows that the system's performance is entirely dictated by the GPU. The CPU is not the bottleneck; it is waiting for the Intel Arc B390 to render each frame. This is evident from the fact that performance scales almost linearly with resolution. At 1080p Low, the CPU could theoretically push hundreds of frames, but the GPU limits it to 115 FPS. At 1080p Ultra, the average is 41 FPS, which is a drop of 74 FPS. This drop is not a result of the CPU being unable to handle the game's physics or draw calls at Ultra settings, but rather the GPU being unable to render the increased visual complexity.

The CPU's 91st percentile ranking compared to the GPU's 9th percentile ranking creates a massive imbalance. The data in the nearestRivals section for the CPU shows it competing with high-end desktop parts like the Intel Core i7-14700F, where it is 2.1% faster. The GPU, on the other hand, is competing with the GeForce GT 710. This system is a prime example of a bottleneck, where a top-tier processor is paired with a graphics solution that severely limits the overall gaming experience.

Measured FPS Breakdown

The measured FPS data reveals a performance profile that is almost entirely dictated by the graphics settings and resolution. The system's peak performance is 115 FPS at 1920x1080 with Low settings. This is the only configuration that approaches a high-refresh-rate experience. As settings are increased at 1080p, the average FPS drops to 81 at Medium, 63 at High, and 41 at Ultra. The 1080p Medium row also provides a min FPS of 69 and a max FPS of 93, indicating some frame-time variance.

At 2560x1440, the performance takes a significant hit. The Low preset yields an average of 73 FPS, which is still playable. However, Medium drops to 51 FPS, High to 40 FPS, and Ultra to 26 FPS. The 1440p Medium row shows a min FPS of 44 and a max of 59. This demonstrates that 1440p is only viable at the lowest settings for a smooth experience, and even then, the frame rate is lower than the 1080p Low result.

The 3840x2160 resolution is where the combination struggles to remain playable. Low settings produce an average of 39 FPS, which is below the standard 60 FPS target. Medium settings yield 27 FPS, with a min of 23 and a max of 31. High settings drop to 21 FPS, and Ultra settings result in an unplayable 14 FPS average. The data clearly shows that 4K gaming is out of the question for this hardware, even at the lowest visual quality preset.

The data pattern is consistent: for every resolution, the jump from Low to Medium results in a significant loss of frames. At 1080p, the drop is 34 FPS (115 to 81). At 1440p, the drop is 22 FPS (73 to 51). At 4K, the drop is 12 FPS (39 to 27). The incremental losses from Medium to High and High to Ultra are also severe, showing that the GPU lacks the raw compute power to handle higher levels of detail. The performance scaling suggests that the system is heavily bound by the GPU's fill rate and memory bandwidth, which are "System Dependent" and "System Shared," respectively.

How This Combo Ranks

The comboRankInGame data places this system at 2417 out of 2740 tested combinations. This ranking is a direct reflection of the GPU's poor performance. A rank of 2417 means that 88% of all tested systems perform better in Fortnite. This is a low ranking, and it is almost entirely attributable to the Intel Arc B390.

The CPU's performance class is irrelevant to this ranking. While the Ryzen 9 9900X3D is a high-end processor, its 91st percentile ranking does not translate to a good gaming experience when paired with a GPU in the 9th percentile. The CPU's performance in synthetic benchmarks, such as its 47737 score in Cinebench R23 multi-core, is a measure of its compute potential, but that potential cannot be utilized in a GPU-bound game like Fortnite.

The nearest rival data for the GPU provides a clear picture of its performance tier. It is 1.3% faster than the NVIDIA GeForce GT 520MX and 2.7% faster than the NVIDIA GeForce GT 710. These are incredibly old and low-powered GPUs. In contrast, the CPU's nearest rivals are modern desktop processors like the Intel Core Ultra 5 245KF and the Intel Core i7-14700F. This juxtaposition highlights the extreme imbalance of this combination. The ranking of 2417 is not a reflection of the CPU's capabilities but rather a sentence imposed by the GPU.

Settings Recommendations

The measured FPS data provides clear guidance for the optimal settings on this system. The primary goal should be to achieve a playable frame rate, which is generally considered to be at least 60 FPS. The data shows that only one configuration achieves this target: 1920x1080 with Low settings, which averages 115 FPS. This is the only preset that provides a comfortable margin above the 60 FPS threshold.

For users with a 1080p monitor, the Low preset is the recommended choice. It is the only way to achieve a smooth, responsive experience. The Medium preset at 1080p, with an average of 81 FPS, is also playable and offers a visual upgrade. The data shows a min FPS of 69 for this setting, which is still above 60, making it a viable alternative for those who prioritize visual quality over maximum frame rates. The High and Ultra presets at 1080p, with averages of 63 and 41 FPS respectively, should be avoided, as the frame rate drops too low to provide a consistent competitive experience.

At 2560x1440, the options are limited. The Low preset, with an average of 73 FPS, is the only recommended configuration. The Medium preset, at 51 FPS, is below the 60 FPS target and will likely feel less smooth. The High and Ultra presets are not recommended for playable frame rates. At 3840x2160, no settings are recommended for competitive play. Even the Low preset, at 39 FPS, is too slow for a game like Fortnite where quick reactions are essential. The data suggests that for the best experience, the system should be used at 1080p with Low or Medium settings. This configuration allows the game to be played at a frame rate that is competitive, while the powerful CPU ensures stable frame pacing.
