Fortnite

AMD Ryzen 5 8400F paired with the Intel Arc B570 delivers a mixed bag in Fortnite, positioning itself as a capable but not elite configuration. The data shows the combo sits at rank 2178 out of 2740 tested combos, placing it in the lower-middle tier of the database. That ranking, however, requires context: the measured frame rates reveal a system that can push high refresh rates at 1080p but struggles to maintain playable performance at 4K, indicating a GPU-bound scenario at higher resolutions and a CPU-bound one at lower settings.

How This Combo Ranks

The combo rank of 2178 out of 2740 combos places this pairing in roughly the 20th percentile of all tested configurations. This is a modest standing, and the data suggests the Arc B570 is the limiting factor for Fortnite’s performance envelope. The GPU’s average benchmark score of 20556 places it in the 65th percentile of all GPUs, while the CPU’s average score of 25005 puts it in the 77th percentile of all CPUs. The gap between these two percentile positions is telling: the processor is significantly stronger relative to its peers than the graphics card, which means the GPU is more likely to become the bottleneck as resolution and settings increase.

Looking at the CPU’s nearest rivals, the Ryzen 5 8400F scores within 0.4% of the Intel Core i7-13620H and 0.3% of the Intel Core i7-11850H, indicating that its compute performance is well understood and competitive for its class. The GPU, meanwhile, sits within 0.1% of the NVIDIA GeForce RTX 3070 Mobile and 0.1% of the Intel Arc A750. This close grouping shows the Arc B570 is a known quantity, but it is not a top-tier part. In Fortnite specifically, the measured FPS numbers show that the combo’s rank is dragged down by the GPU’s inability to sustain high frame rates at 4K, where the average drops to just 32 FPS on High settings.

GPU Role

The Intel Arc B570’s specifications are modest for Fortnite’s demands, and the measured FPS data confirms that its role is the decisive factor in this combo’s performance. The GPU features 10 GB of GDDR6 memory on a 160-bit bus, delivering a bandwidth of 380.0 GB/s. Its base and boost clocks are both set at 2500 MHz, with memory clocked at 2375 MHz (19 Gbps effective). These figures are not exceptional, but they are paired with 2304 shading units, 144 texture mapping units, and 80 raster operations pipelines. The pixel rate is 200.0 GPixel/s, and the texture rate is 360.0 GTexel/s, with an FP32 throughput of 11.52 TFLOPS.

In Fortnite, the GPU’s memory configuration becomes relevant when comparing resolutions. The 10 GB VRAM is adequate for 1080p and 1440p, but at 4K the frame rates suggest the card is running out of headroom. The data shows that at 2560x1440 with High settings, the average FPS is 61, which is exactly the threshold for smooth 60Hz gameplay. At 3840x2160 with the same settings, the average drops to 32 FPS, a near-halving that aligns with the GPU’s limited compute resources. The GPU’s benchmark percentile of 65 and its close rivalry with the Arc A750 (deltaPct of -0.1%) indicate that it is a mid-range part, and Fortnite’s performance reflects that positioning.

Measured FPS Breakdown

The measured FPS data provides a clear picture of how this combo scales across resolutions and settings. At 1920x1080, the results are strong for competitive play. Low settings deliver an average of 176 FPS, Medium settings yield 124 FPS (with a minimum of 106 and maximum of 143), High settings produce 96 FPS, and Ultra settings drop to 64 FPS. This is a playable range, with even Ultra settings breaking the 60 FPS barrier.

Moving to 2560x1440, the frame rates show significant scaling. Low settings average 112 FPS, which is still excellent for high-refresh monitors. Medium settings average 79 FPS (minimum 67, maximum 91), High settings average 61 FPS, and Ultra settings fall to 40 FPS. These numbers suggest that 1440p is viable for medium to high settings, but Ultra becomes a stretch.

At 3840x2160, the combo struggles. Low settings average 59 FPS, which is barely playable. Medium settings drop to 42 FPS (minimum 35, maximum 48), High settings fall to 32 FPS, and Ultra settings plummet to 21 FPS. None of these 4K results are ideal for a smooth experience, and the data strongly implies that this resolution is beyond the GPU’s intended capability for Fortnite.

Resolution Scaling

The scaling from 1080p to 4K reveals a clear bottleneck story. At Low settings, the average FPS drops from 176 at 1920x1080 to 112 at 2560x1440 (a 36% decrease) and then to 59 at 3840x2160 (a 47% decrease from 1440p). This is a substantial performance loss that tracks with the GPU’s pixel throughput limitations. The pixel rate of 200.0 GPixel/s and the FP32 compute of 11.52 TFLOPS are being saturated as the resolution increases.

For High settings, the scaling is even more pronounced: 96 FPS at 1080p drops to 61 FPS at 1440p (a 36% decrease) and then to 32 FPS at 4K (a 48% decrease from 1440p). This pattern indicates that the GPU is the limiting component, as the CPU’s relative strength (77th percentile) does not compensate for the GPU’s mid-range position. If the CPU were the bottleneck, we would expect to see less variation between resolutions at the same settings. Instead, the data shows that every step up in resolution costs roughly a third to half of the frame rate, which is characteristic of a GPU-bound scenario.

The Ultra settings scaling is similarly steep: 64 FPS at 1080p, 40 FPS at 1440p, and 21 FPS at 4K. This suggests that the combination of high resolution and demanding settings exceeds what the Arc B570 can handle, making 4K Ultra a non-starter for this pairing.

Settings Recommendations

Based on the measured FPS rows, the best experience for this combo depends on the target resolution. At 1920x1080, High settings provide an average of 96 FPS, which is ideal for most gamers seeking a balance between visual quality and smoothness. For those prioritizing competitive performance, Low settings at 176 FPS is the clear choice, but the jump from Low to Medium (124 FPS) is a reasonable trade-off for improved visuals.

At 2560x1440, Medium settings offer an average of 79 FPS with a minimum of 67 FPS, making it the most reliable option for a steady 60Hz experience. High settings at 61 FPS are playable but leave little headroom for dips, while Low settings at 112 FPS are excellent for fast-paced play. Ultra settings at 40 FPS are not recommended, as the frame rate falls below the threshold for smooth gameplay.

At 3840x2160, none of the settings deliver a consistently smooth experience. Low settings at 59 FPS are the only option that approaches playability, but even this is marginal. Medium settings at 42 FPS and High settings at 32 FPS are not viable for most players. The data suggests that 4K should be avoided unless the user is willing to accept significant compromises.

CPU Role

The AMD Ryzen 5 8400F is a 6-core, 12-thread processor based on the Zen 4 architecture, manufactured on a 4 nm process by TSMC. It has a base clock of 4.20 GHz and a boost clock of 4.70 GHz, with a TDP of 65 W. The CPU features 64 KB of L1 cache per core, 1 MB of L2 cache per core, and 16 MB of shared L3 cache. Its memory support is DDR5 with a dual-channel bus, offering a bandwidth of 83.2 GB/s. These specifications are solid for gaming, and the CPU’s benchmark scores reflect that: it achieves 20851 in Cinebench R23 multicore and 2943 in single-core, with a Passmark multithread score of 24389 and a single-thread score of 3685.

In Fortnite, the CPU’s role is to feed frames to the GPU, and the data shows it does so effectively at lower resolutions. At 1080p Low, the combo hits 176 FPS, which is a strong result that likely approaches the CPU’s limit for this game. However, the CPU’s percentile of 77 versus the GPU’s 65 suggests that the processor has more headroom than the graphics card. This is confirmed by the resolution scaling: if the CPU were the bottleneck, we would see similar FPS numbers across resolutions at the same settings. Instead, the FPS drops consistently as resolution increases, indicating the GPU is the primary constraint. The CPU’s 12 threads and high boost clock are sufficient to avoid becoming a limiting factor in Fortnite, which is known to favor higher clock speeds over core counts. The nearest rivals, including the Ryzen 5 7500F with a deltaPct of 0.2%, show that this CPU is competitive for its class, but it is paired with a GPU that cannot fully exploit its potential at higher resolutions.
