GPU Role

The Intel Arc B370 is the primary graphics processor in this configuration, and its specifications paint a clear picture of its performance tier. It is an integrated graphics processor (IGP) based on the Xe3-LPG architecture with a 25 W TDP. The GPU operates at a base clock of 300 MHz and can boost up to 2400 MHz. It has 1280 shading units, 40 texture mapping units (TMUs), and 20 render output units (ROPs). The pixel rate is listed at 48.00 GPixel/s, and the texture rate is 96.00 GTexel/s, with FP32 performance rated at 6.144 TFLOPS.

The most critical specification, however, is its memory configuration. The Arc B370's memory size, type, and bus width are all listed as "System Shared." This means it does not have dedicated VRAM and must utilize a portion of the system's main memory, with the bandwidth being "System Dependent." This is a severe limitation for a game like Fortnite, which requires high memory bandwidth to stream textures and geometry. The lack of dedicated VRAM likely forces the system to rely on slower system memory, contributing to lower frame rates, especially at higher resolutions and texture quality settings.

The GPU's 3DMark Steel Nomad DX12 score of 1184 places it in the 5th percentile of all GPUs. Its nearest rivals are all legacy parts from the early 2010s, such as the ATI Radeon HD 5770 and AMD Radeon HD 7650M. This score indicates that the graphics core's raw compute power is comparable to that of a mid-range discrete GPU from over a decade ago. The benchmark results show that this GPU is the limiting factor in this system; it simply does not have the processing power or the memory bandwidth to feed the high frame rates that the CPU is capable of producing.

CPU Role

The AMD Ryzen 7 5800X3D is a desktop processor from the Ryzen 7 series, built on the Zen 3 architecture (codename Vermeer). It features 8 cores and 16 threads, with a base clock of 3.40 GHz and a boost clock of 4.50 GHz. A key feature is its large 96 MB of shared L3 cache, which is part of the "X3D" branding and is designed to improve gaming performance by reducing memory latency. The processor has a 105 W TDP and uses the AMD Socket AM4 platform.

This CPU is a powerhouse in synthetic benchmarks, with an average benchmark score of 27896, placing it in the 80th percentile of all CPUs. In Cinebench R23, it scores 14317 points in the multi-core test and 1452 points in the single-core test. Its performance is closely matched by rivals such as the AMD Ryzen 7 6800U (scoring 27887, a 0% delta) and the Intel Core i9-10900K (scoring 27872, a 0.1% delta). The passmark multi-thread score is 28309, and the single-thread score is 3234.

Given its high percentile ranking and strong multi-core and single-core scores, the CPU is more than capable of handling Fortnite's game logic, physics, and draw calls. The data suggests that in this configuration, the CPU is rarely, if ever, the bottleneck. The 5800X3D is capable of pushing far beyond the frame rates measured in this test, but it is held back by the Intel Arc B370's inability to render frames quickly enough. The CPU's high core count and fast clocks are likely underutilized, as the GPU struggles to keep up even at lower settings.

How This Combo Ranks

The combined system ranks 2517th out of 2740 tested combos in Fortnite. This places it in the bottom 8% of all systems tested, a position that is heavily influenced by the GPU's performance. This ranking is paradoxical when considering the CPU's strength. The Ryzen 7 5800X3D's 80th percentile CPU ranking is in stark contrast to the GPU's 5th percentile ranking. The system's overall performance is dragged down by the weakest link in the chain.

The data implies that the combo's ranking is not a reflection of the CPU's gaming capabilities, but rather a direct result of the Arc B370's limitations. The GPU's 3DMark score of 1184 is nearly identical to that of the ATI Radeon HD 5770, which was a mid-range card in 2009. This pairing creates a significant imbalance. While the CPU can handle the most complex game scenarios, the GPU will struggle to render them at playable frame rates in many cases. The combo's low rank confirms how critical the graphics processor is for a game like Fortnite, which relies heavily on the GPU for its rendering pipeline.

Resolution Scaling

The measured FPS data shows a clear and predictable degradation in performance as resolution increases, but the pattern is telling about the system's bottleneck. At 1920x1080 with Low settings, the system achieves an average of 104 FPS. When resolution is increased to 2560x1440, that average drops to 66 FPS. At 3840x2160, it falls further to 35 FPS. This is a 66% reduction in frame rate from 1080p to 4K at Low settings.

For High settings, the progression is from 57 FPS at 1080p, to 36 FPS at 1440p, and down to 19 FPS at 4K. This scalability suggests that the GPU is the primary limiting factor. The workload on the GPU increases with the number of pixels, and the Arc B370's limited fill rate and bandwidth are quickly overwhelmed. If the CPU were the bottleneck, the frame rates would not drop so dramatically with increasing resolution, because the CPU's workload (draw calls, physics) remains relatively constant across resolutions. The sharp drop in FPS as resolution scales up confirms that the Intel Arc B370 is the component that dictates the system's performance ceiling in Fortnite.

Measured FPS Breakdown

The measured data provides a comprehensive view of the system's performance across multiple settings and resolutions. At 1920x1080, the system delivers an average of 104 FPS on Low settings. Medium settings yield an average of 73 FPS, with minimum and maximum values of 62 and 84 FPS respectively. High settings bring the average down to 57 FPS, while the Ultra preset results in an average of 37 FPS.

Moving to 2560x1440, the performance is significantly reduced. Low settings produce an average of 66 FPS. Medium settings deliver an average of 46 FPS (min 39, max 53). High settings average 36 FPS, and Ultra settings average 24 FPS. At 3840x2160, the system is heavily strained. Low settings average 35 FPS. Medium settings average 25 FPS (min 21, max 28). High settings average 19 FPS, and Ultra settings drop to an average of just 13 FPS.

These numbers illustrate a system that can approach smooth, playable frame rates, but only at the lowest resolution and settings. The performance gap between Low and Ultra is massive, with the 1080p Low setting achieving 104 FPS compared to just 37 FPS at 1080p Ultra, a 181% difference. The data indicates that for a consistently playable experience, the player must make significant compromises in visual fidelity.

Settings Recommendations

Based on the measured FPS data, the optimal settings for this configuration are heavily dependent on the target resolution and desired frame rate. At 1920x1080, the Low preset is the only setting that provides a comfortably smooth experience, averaging 104 FPS. This is the recommended preset for competitive play where high frame rates are more important than visual quality. The Medium preset, at 73 FPS, is also viable for a more balanced experience, offering a smoother visual presentation than Low while still maintaining a frame rate above 60 FPS.

For 2560x1440, the Medium preset averages 46 FPS, which is playable but not ideal. The Low preset, averaging 66 FPS, is the recommended choice for this resolution to ensure a smoother experience. At 3840x2160, no preset achieves a consistently playable frame rate. The Low preset, at 35 FPS, is the only one that approaches playability, but it will likely feel choppy. The data suggests that this system is not suitable for 4K gaming in Fortnite. The Ultra preset is not recommended at any resolution, as it yields average frame rates of 37 FPS, 24 FPS, and 13 FPS at 1080p, 1440p, and 4K respectively. The best experience is achieved by using Low or Medium settings at 1080p, with Low at 1440p being a viable alternative for higher resolution with a moderate frame rate.
