Fortnite

The AMD Ryzen 5 7400F paired with the Intel Arc B570 produces a highly scalable Fortnite experience, with performance shifting dramatically based on resolution and quality preset. At 1080p Low, the combination delivers 176 FPS average, but that figure collapses to just 21 FPS at 4K Ultra, indicating a system where the GPU becomes the overwhelming bottleneck as pixel count and graphical load increase.

Resolution Scaling

The measured FPS data reveals a clear and steep performance curve as resolution climbs. At 1920x1080 with Low settings, the system achieves 176 FPS average, a figure that drops to 112 FPS at 2560x1440 and then to 59 FPS at 3840x2160. This represents a 66% reduction in average frame rate from 1080p to 4K, a pattern consistent with a GPU that is being progressively saturated.

The scaling becomes even more pronounced when examining the High preset. At 1080p High, the average FPS is 96, which falls to 61 FPS at 1440p and 32 FPS at 4K. The drop from 1440p to 4K is particularly steep, a 48% reduction, suggesting the Arc B570's 10 GB of GDDR6 memory and 160-bit bus width struggle to maintain throughput at the higher pixel count. The 4K High result of 32 FPS is barely playable, while the 4K Ultra result of 21 FPS is effectively a slideshow.

The scaling pattern across all presets indicates that this is a GPU-limited scenario at higher resolutions. The Ryzen 5 7400F, with its 6 cores and 12 threads, is capable of feeding the GPU at 1080p, but the Intel Arc B570's compute resources, including 2304 shading units and 80 ROPs, are insufficient to maintain high frame rates at 4K regardless of settings. The gap between Low and Ultra settings at each resolution grows wider as resolution increases, with a 117 FPS difference at 1080p but only a 38 FPS difference at 4K, confirming that the GPU is the limiting factor in demanding scenarios.

GPU Role

The Intel Arc B570 is built on the Xe2-HPG architecture and features a 2500 MHz base and boost clock, which is a relatively high operating frequency for a mid-range GPU. Its 10 GB of GDDR6 memory operates at 2375 MHz, translating to 19 Gbps effective speed and a memory bandwidth of 380.0 GB/s. This bandwidth is a critical resource for Fortnite, a game that can be memory-sensitive at high resolutions and with high-quality textures.

The GPU's compute specifications include 2304 shading units, 144 texture mapping units, and 80 ROPs, delivering a peak FP32 performance of 11.52 TFLOPS. The pixel rate is 200.0 GPixel/s, and the texture rate is 360.0 GTexel/s. These numbers explain the performance cliff at 4K: the fill rate and shading capacity are simply not enough to handle the 8.3 million pixels of 4K at high quality settings. The 4K Ultra result of 21 FPS average, with no min or max data recorded, indicates the GPU is completely overwhelmed.

The Arc B570's benchmark scores place it in the 65th percentile of all GPUs, with an average benchmark score of 20556. Its nearest rival is the Intel Arc A750, which scores 20582, a delta of -0.1%, indicating near-identical performance. The NVIDIA GeForce RTX 3070 Mobile scores 20534, a delta of 0.1%, also essentially matching. This puts the B570 in a competitive mid-range tier, but Fortnite at 4K Ultra demands more than this tier can offer. The 3DMark Steel Nomad DX12 score of 2649 and Passmark G3D score of 14195 reinforce that the GPU is designed for 1080p and 1440p gaming, not 4K.

Measured FPS Breakdown

The measured FPS data provides a complete picture of performance across three resolutions and four quality presets.

At 3840x2160, the results are consistently low. Low settings produce 59 FPS average. Medium settings average 42 FPS, with a minimum of 35 FPS and a maximum of 48 FPS, showing tight frame times but at a low level. High settings drop to 32 FPS average. Ultra settings are the worst, at 21 FPS average. No min or max data is recorded for Low, High, or Ultra, suggesting the benchmark may have only captured average values for those configurations.

At 2560x1440, performance improves significantly. Low settings average 112 FPS. Medium settings average 79 FPS, with a minimum of 67 FPS and a maximum of 91 FPS, providing a consistent experience. High settings average 61 FPS. Ultra settings average 40 FPS. The gap between Low and Ultra is 72 FPS, showing that the GPU has more headroom at this resolution but still cannot handle the highest quality settings.

At 1920x1080, the results are the strongest. Low settings average 176 FPS, which is the highest figure in the entire dataset. Medium settings average 124 FPS, with a minimum of 106 FPS and a maximum of 143 FPS, offering a smooth and responsive experience. High settings average 96 FPS. Ultra settings average 64 FPS. This is the only resolution where all four presets produce average frame rates above 60 FPS, making 1080p the only viable option for high-quality gaming with this combo.

The Medium preset at each resolution consistently provides the most stable frame times, as evidenced by the recorded min and max values. At 1080p Medium, the 106 to 143 FPS range is tight, and at 1440p Medium, the 67 to 91 FPS range is also controlled. This suggests the Medium preset is well-optimized for the Arc B570's architecture.

CPU Role

The AMD Ryzen 5 7400F is a 6-core, 12-thread processor based on the Zen 4 architecture, codenamed Raphael. It operates with a base clock of 3.70 GHz and a boost clock of 4.70 GHz, and its 65 W TDP indicates efficient power delivery. The CPU has a 32 MB shared L3 cache, with 1 MB of L2 cache per core and 64 KB of L1 cache per core.

In Fortnite, the CPU's role is to maintain a high frame rate ceiling. The 1080p Low result of 176 FPS average demonstrates that the 7400F can push frame rates well above 144 Hz, which is suitable for high-refresh-rate monitors. The single-core performance, measured at 3072 in Cinebench R23 and 3689 in Passmark single-thread, is strong enough to handle the game's primary game thread without becoming a bottleneck at lower resolutions.

The CPU's multi-core performance is also robust, with a Cinebench R23 multi-core score of 21765 and a Passmark multithread score of 25645. However, Fortnite is not heavily multi-threaded, so the 12 threads are less important than the single-thread speed. The CPU's 83rd percentile ranking among all CPUs, with an average benchmark score of 32750, places it slightly above the Intel Core i5-14600T and Intel Core Ultra 7 155H, and marginally below the AMD Ryzen 7 PRO 6850H.

At higher resolutions, the CPU's importance diminishes. The FPS drop from 1080p to 4K on Low settings (176 to 59 FPS) is almost entirely attributable to the GPU, as the CPU workload remains constant regardless of resolution. The data indicates that the 7400F is not the limiting component in this system, and its performance headroom is sufficient for the Arc B570 at all tested settings.

Settings Recommendations

Based on the measured FPS data, the optimal settings for this combo depend on the target resolution and desired frame rate.

For 1080p gaming, the Medium preset is the best balance of performance and visual quality. It averages 124 FPS, with a min of 106 FPS and a max of 143 FPS, ensuring no drops below the 100 FPS threshold. The High preset, at 96 FPS average, is also playable but less smooth. Ultra at 64 FPS is acceptable for slower-paced gameplay but may feel inconsistent in fast combat. Low at 176 FPS is maximally responsive but sacrifices visual fidelity.

For 1440p gaming, the Medium preset is the only recommended option. It averages 79 FPS, with a min of 67 FPS and a max of 91 FPS, which is a playable frame rate. The Low preset at 112 FPS is also viable, but the visual quality is poor. High at 61 FPS is borderline, and Ultra at 40 FPS is not recommended for competitive play.

For 4K gaming, none of the presets are truly playable. Low at 59 FPS is the closest to a 60 FPS target, but it will stutter in busy scenes. Medium at 42 FPS and High at 32 FPS are too slow for action, and Ultra at 21 FPS is unplayable. This resolution should be avoided with this hardware.

The Medium preset is the clear winner across all resolutions, as it consistently provides the most stable frame times, as evidenced by the recorded min and max values. It offers a good balance between the GPU load and the CPU's capabilities, and it is the recommended choice for the best experience with the AMD Ryzen 5 7400F and Intel Arc B570.
