Fortnite

The AMD Ryzen 5 5600F and Intel Arc B370 pairing delivers playable performance at 1080p, but the data shows a hard ceiling as resolution climbs. This is a combination where the GPU becomes the dominant constraint early, and the measured frames reflect a system that is best suited for competitive settings rather than visual fidelity.

Resolution Scaling

The measured FPS data shows a steep and consistent decline as resolution increases across all settings presets. At Low settings, the average frame rate drops from 104 FPS at 1920x1080 to 66 FPS at 2560x1440, and finally to 35 FPS at 3840x2160. That represents a 36.5% performance loss when moving from 1080p to 1440p, and a further 47% loss when moving from 1440p to 4K. The scaling is similarly harsh on the Medium preset, which falls from 73 FPS at 1080p to 46 FPS at 1440p and 25 FPS at 4K.

The High preset shows the same pattern: 57 FPS at 1080p, 36 FPS at 1440p, and 19 FPS at 4K. Ultra settings are the most punishing, starting at 37 FPS at 1080p and collapsing to 24 FPS at 1440p and 13 FPS at 4K. The pattern here is unambiguous — the frame rate drops are far larger than what would be expected from a CPU-limited scenario. The data indicates that the Intel Arc B370, which carries a 5th percentile ranking among all GPUs and a 3DMark Steel Nomad score of 1184, is the limiting component in this configuration. Its nearest rivals in synthetic benchmarks are legacy parts like the ATI Radeon HD 5770 and AMD FirePro M2000, which places it in a performance tier that simply cannot sustain high frame rates at higher resolutions.

At 1080p, the system manages a respectable 104 FPS on Low, which suggests the CPU is doing its share of the work. The Ryzen 5 5600F, with its PassMark single-thread score of 2872 and multithread score of 19236, sits at the 85th percentile of all CPUs. That is a strong result, but the GPU’s 5th percentile position is the bottleneck. The scaling curve confirms this: if the CPU were the constraint, the 4K numbers would not drop so dramatically relative to 1080p. Instead, the data shows a GPU that is overwhelmed by pixel count.

CPU Role

The Ryzen 5 5600F is a 6-core, 12-thread processor based on the Zen 3 architecture, running on the AMD Socket AM4 platform. It has a base clock of 3.00 GHz and a boost clock of 4.00 GHz, with a 65 W TDP. The 32 MB shared L3 cache and 4,150 million transistors on a 7 nm TSMC process give it solid fundamentals for gaming workloads. In synthetic tests, it scores 59,339 in integer math, 34,548 in floating-point math, and 23,422 in random string sorting. These numbers place it in the upper tier of desktop processors, and its nearest rivals in aggregate benchmark score are the Intel Core Ultra 5 225, the AMD Ryzen 5 5500X3D, and the AMD Ryzen AI 7 PRO 450, all within 0.5% of its average score of 36,945.

For Fortnite specifically, the CPU has enough headroom to push well beyond what the GPU can deliver. At 1080p Low, the system hits 104 FPS, which is a solid competitive frame rate. The fact that the same CPU with a more capable GPU would likely produce higher numbers is evident from the benchmark data — the CPU’s PassMark physics score of 1,043 and data encryption score of 13,839 are respectable, but the GPU’s 6.144 TFLOPS FP32 performance and 48.00 GPixel/s pixel rate are the limiting factors. The CPU’s role here is to feed the GPU adequately at lower resolutions, and the data shows it does that without causing a hard bottleneck at 1080p. At higher resolutions, the CPU becomes irrelevant because the GPU is so far behind.

The 12 threads and 6 cores are sufficient for modern Fortnite builds, and the 4.00 GHz boost clock ensures that single-threaded game logic is handled well. However, the data does not suggest that more CPU headroom would help this specific pairing. Moving from 1080p to 1440p at Low settings drops the frame rate by 36.5%, and that is purely a GPU limitation. The CPU’s benchmark scores, including its 85th percentile ranking, indicate it is not the weak link.

Settings Recommendations

The measured rows provide a clear picture of what this system can achieve. At 1920x1080, the Low preset delivers 104 FPS average, which is the only setting that breaks the 100 FPS threshold. The Medium preset at 1080p achieves 73 FPS with a minimum of 62 FPS and a maximum of 84 FPS, which is still playable but noticeably lower. The High preset drops to 57 FPS, and Ultra falls to 37 FPS. Based on this data, the Low preset at 1080p is the recommended configuration for players who prioritize smooth, responsive gameplay. The 104 FPS average provides a significant margin above the 62 FPS minimum seen on Medium, which suggests more consistent frame pacing.

At 2560x1440, the Low preset manages 66 FPS, which is playable but not ideal for fast-paced battles. The Medium preset drops to 46 FPS, and High falls to 36 FPS. The Ultra preset at 1440p is effectively unplayable at 24 FPS. At 3840x2160, even the Low preset only manages 35 FPS, and the High preset drops to 19 FPS. The data strongly suggests that 4K is not a viable option for this pairing, regardless of settings. The Ultra preset at 4K produces a 13 FPS average, which is a slideshow.

For the best experience, the recommendation is to run the Low preset at 1080p. This provides the highest frame rate and the lowest input latency, which matters in a competitive Battle Royale. If visual quality is more important than frame rate, the Medium preset at 1080p is a compromise, but the 73 FPS average is a significant step down. The High and Ultra presets at 1080p are not recommended because they drop below 60 FPS, which is a common threshold for smooth gameplay. At higher resolutions, the data shows diminishing returns — the Low preset at 1440p is the only viable option above 1080p.

GPU Role

The Intel Arc B370 is an integrated graphics solution based on the Xe3-LPG architecture, built on a 3 nm process by Intel. It has a base clock of 300 MHz and a boost clock of 2400 MHz, with 1280 shading units, 40 texture mapping units, and 20 raster output pipelines. It includes 10 ray tracing cores and supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4. The memory is system shared, with bandwidth described as system dependent, which means the GPU relies on the CPU’s DDR4 memory subsystem.

The GPU’s synthetic benchmark results are modest. It scores 1,184 in the 3DMark Steel Nomad DX12 test, which places it in the 5th percentile of all GPUs. Its nearest rivals are the ATI Mobility Radeon HD 5570 at 1,186, the ATI Radeon HD 5770 at 1,190, and the AMD Radeon HD 7650M at 1,192 — all within 0.7% of its score. The AMD FirePro M2000 trails at 1,168, which is 1.4% behind. These comparisons place the Arc B370 in a legacy performance tier, which explains its difficulty with Fortnite at higher resolutions.

The GPU’s pixel rate of 48.00 GPixel/s and texture rate of 96.00 GTexel/s are low by modern standards. The FP32 throughput of 6.144 TFLOPS is sufficient for light 1080p gaming, but the data shows it struggles as resolution increases. At 1080p Low, the GPU delivers 104 FPS, which is a respectable result for an integrated part. However, at 4K Low, the frame rate drops to 35 FPS, and at 4K Ultra, it falls to 13 FPS. This performance curve is characteristic of a GPU with insufficient fill rate and memory bandwidth for high-resolution workloads.

The system shared memory is a notable constraint. Since the GPU has no dedicated VRAM, it must compete with the CPU for memory bandwidth. The CPU’s memory bandwidth is rated at 51.2 GB/s over a dual-channel DDR4 bus, which is shared with the GPU. This shared bandwidth likely contributes to the severe frame rate drops at higher resolutions, where the GPU needs more data per frame. The 25 W TDP and IGP slot width confirm this is not a high-performance discrete part, but rather an integrated solution meant for basic gaming and productivity.

Measured FPS Breakdown

At 1920x1080, the system produces its best results. The Low preset averages 104 FPS, which is the highest measured frame rate in the entire dataset. The Medium preset averages 73 FPS, with a minimum of 62 FPS and a maximum of 84 FPS. The High preset drops to 57 FPS, and the Ultra preset averages 37 FPS. The gap between Low and Ultra at 1080p is 67 FPS, which is a significant range that shows the GPU’s sensitivity to settings changes.

At 2560x1440, the performance drops noticeably. The Low preset averages 66 FPS, which is a 36.5% reduction from the 1080p result. The Medium preset averages 46 FPS, with a minimum of 39 FPS and a maximum of 53 FPS. The High preset averages 36 FPS, and the Ultra preset drops to 24 FPS. The Medium preset’s minimum of 39 FPS is below the 60 FPS threshold, which indicates that even modest settings at 1440p will result in noticeable stuttering during intense scenes.

At 3840x2160, the system is severely constrained. The Low preset averages 35 FPS, the Medium preset averages 25 FPS with a minimum of 21 FPS and maximum of 28 FPS, the High preset averages 19 FPS, and the Ultra preset averages 13 FPS. None of these results are playable for a competitive Battle Royale. The gap between Low and Ultra at 4K is 22 FPS, which shows that settings changes have a smaller absolute impact at this resolution because the GPU is already overwhelmed.

The data is consistent across all resolutions: the Low preset provides the best frame rate, followed by Medium, High, and Ultra in descending order. The Medium preset is the only one that provides minimum and maximum FPS values in the dataset, with a 21-28 FPS range at 4K, a 39-53 FPS range at 1440p, and a 62-84 FPS range at 1080p. This suggests the Medium preset has the most variable performance, likely due to the GPU being pushed into different thermal or power states. For players seeking the most stable experience, the Low preset at 1080p is the clear choice, as it delivers 104 FPS with no reported minimum dips, suggesting a consistent frame delivery. The combination of the 85th percentile CPU and 5th percentile GPU produces a system that is firmly entry-level for Fortnite, with the measured results showing that 1080p Low is the only configuration that fully utilizes the CPU’s capabilities.
