# Fortnite with AMD Ryzen 5 7400F + Intel Arc B370

This pairing of AMD's 6-core Zen 4 desktop processor with Intel's integrated-class Arc B370 graphics produces playable frame rates only at 1080p with reduced settings, and the data shows a system that is overwhelmingly GPU-limited across every resolution tested. The Ryzen 5 7400F is a strong modern CPU — sitting in the 83rd percentile of all CPUs with an average benchmark score of 32,750 — while the Arc B370 lands in just the 5th percentile among GPUs with an average score of 1,184. That massive gap defines every result in this Fortnite test run.

FAQ

Q: What is the best resolution to play Fortnite with this combo?

A: 1920x1080 is the only resolution where the average frame rate exceeds 60 FPS, and only at Low settings (104 FPS). At 1440p, the best result is 66 FPS at Low, while 4K tops out at 35 FPS at Low.

Q: How does the Arc B370 compare to its nearest GPU rivals?

A: The Arc B370 scores 1,184 in 3DMark Steel Nomad DX12. That is virtually identical to the ATI Mobility Radeon HD 5570 (1,186, delta -0.2%) and ATI Radeon HD 5770 (1,190, delta -0.5%), while sitting 1.4% ahead of the AMD FirePro M2000 (1,168).

Q: Is the Ryzen 5 7400F holding back the Arc B370?

A: No. The CPU is far more capable than the GPU. The Ryzen 5 7400F scores 21,765 in Cinebench R23 multi-core and 3,072 in single-core, placing it in the 83rd percentile of all CPUs. The Arc B370's 5th percentile GPU ranking means the graphics solution is the clear bottleneck.

Q: How much FPS do you lose going from 1080p to 4K at the same settings?

A: At Low settings, average FPS drops from 104 at 1080p to 66 at 1440p (a 36% reduction) and then to 35 at 4K (a 66% reduction from 1080p). At High settings, the drop is from 57 to 36 to 19 across the same resolutions.

Q: What is the highest FPS this combo achieves in Fortnite?

A: The highest measured average is 104 FPS at 1920x1080 with Low settings. The next best is 73 FPS at 1080p Medium, followed by 66 FPS at 1440p Low.

Q: How does this combo rank among all tested combinations?

A: It ranks 2,517 out of 2,740 total combos in Fortnite, placing it in the bottom 8% of all tested CPU-GPU pairings for this game.

GPU Role

The Intel Arc B370 is an integrated graphics processor with 1,280 shading units, 40 texture mapping units, and 20 raster output units. It operates at a 300 MHz base clock and boosts to 2,400 MHz, with a 25 W TDP. The GPU has 10 ray tracing cores and supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Its pixel rate is 48.00 GPixel/s and texture rate is 96.00 GTexel/s, delivering 6.144 TFLOPS of FP32 performance.

Critically, the Arc B370 uses system shared memory for both its frame buffer and bandwidth. This means the GPU's memory performance is entirely dependent on the host system's DDR5 RAM, and the memory bus width is also system dependent. This architecture explains why the GPU struggles so severely at higher resolutions — it must compete with the CPU for memory bandwidth, and the shared memory design limits effective throughput in memory-intensive scenarios like 4K rendering.

The GPU's 3DMark Steel Nomad DX12 score of 1,184 places it in the 5th percentile of all GPUs. Its nearest rivals are all legacy ATI parts from over a decade ago: the Mobility Radeon HD 5570 (1,186), Radeon HD 5770 (1,190), and Radeon HD 7650M (1,192). The Arc B370 trails the HD 7650M by 0.7%, while beating the FirePro M2000 by 1.4%. These comparisons underscore that this is entry-level integrated graphics performance, not discrete GPU territory.

In Fortnite specifically, the GPU's limitations dominate all measured results. Even the best case scenario — 1080p Low at 104 FPS — is a modest result by modern standards. The ray tracing cores present in the Arc B370 are essentially irrelevant in this test data, as Fortnite's measured settings do not show any ray tracing configuration, and the frame rates at Ultra settings suggest the hardware cannot handle the additional rendering complexity.

Resolution Scaling

The measured FPS data reveals a classic GPU-bound scaling pattern. At 1080p Low, the combo achieves 104 FPS. Moving to 1440p Low drops that to 66 FPS — a 36.5% reduction. At 4K Low, the average falls to 35 FPS, which is a 66.3% reduction from 1080p and a 47% reduction from 1440p. These are steep drops that indicate the GPU is saturated at even the lowest settings.

At High settings, the scaling is even more punishing: 57 FPS at 1080p, 36 FPS at 1440p (36.8% drop), and 19 FPS at 4K (66.7% drop from 1080p). The consistency of these percentage drops across Low and High settings suggests the bottleneck is purely the GPU's rendering throughput scaling with pixel count, rather than any CPU limitation or settings-specific constraint.

The Medium settings tell a similar story with additional data points. At 1080p Medium, the combo averages 73 FPS with a minimum of 62 and maximum of 84. At 1440p Medium, that falls to 46 FPS (min 39, max 53). At 4K Medium, the average is 25 FPS (min 21, max 28). The minimum FPS figures at Medium settings show that frame pacing remains reasonably stable — the 4K min of 21 FPS is only 4 FPS below the average, and the 1440p min of 39 is 7 FPS below its 46 FPS average.

The Ultra settings are nearly unplayable at any resolution. The combo manages 37 FPS at 1080p Ultra, 24 FPS at 1440p Ultra, and just 13 FPS at 4K Ultra. These numbers confirm that the Arc B370 lacks the raw compute power for high-fidelity rendering, regardless of the capable CPU paired with it.

The scaling behavior strongly indicates that the Ryzen 5 7400F is not the limiting factor. The CPU's Cinebench R23 multi-core score of 21,765 and single-core score of 3,072 are robust figures that would support much higher frame rates in Fortnite if paired with a stronger GPU. The fact that FPS scales almost linearly with pixel count — halving as resolution roughly doubles — points entirely to the GPU as the constraint.

Settings Recommendations

Based on the measured data, the only truly playable configuration is 1920x1080 with Low settings, which produces 104 FPS on average. This is the sole combination that clears the 60 FPS threshold comfortably. The 1080p Medium preset delivers 73 FPS, which is also serviceable for competitive play, though it comes with a 30% FPS penalty compared to Low.

For players who prioritize smoothness over visual fidelity, 1080p Low is the clear choice. The 104 FPS average at this setting provides headroom above 60 FPS, which helps absorb frametime spikes during busy scenes. The 1080p Medium preset's 73 FPS average (min 62, max 84) is the second-best option and still maintains a minimum above 60 FPS, making it viable if the visual upgrade is worth the frame rate cost.

At 1440p, Low settings are the only viable option, producing 66 FPS. This is above the 60 FPS threshold but leaves little margin. The 1440p Medium preset drops to 46 FPS, which will feel noticeably less smooth, and the 1440p High preset at 36 FPS is borderline for gameplay. The 1440p Ultra preset at 24 FPS is not recommended.

At 4K, no setting is truly playable. The best result is 35 FPS at Low, which is below the 60 FPS target and at the edge of what most players would consider acceptable. The 4K Medium preset at 25 FPS and 4K High at 19 FPS are both too slow for a fast-paced battle royale. The 4K Ultra preset at 13 FPS is effectively a slideshow.

For the best balance of visual quality and performance, the 1080p Medium preset appears to be the sweet spot. It delivers 73 FPS average with a minimum of 62 FPS, keeping gameplay above the critical 60 FPS floor while offering improved visuals over Low. However, for competitive play where maximum frame rate matters, 1080p Low at 104 FPS is the optimal choice.

How This Combo Ranks

This Ryzen 5 7400F + Arc B370 combination ranks 2,517 out of 2,740 tested combos in Fortnite, placing it in the bottom 8.1% of all configurations. The ranking is unsurprising given the GPU's 5th percentile standing among all graphics processors. The CPU, by contrast, sits in the 83rd percentile among all processors, which suggests the combo's poor rank is almost entirely attributable to the GPU.

The CPU's nearest rivals in overall benchmark performance are the Intel Core i5-14600T (avg score 32,707, delta 0.1%), Intel Core Ultra 7 155H (32,697, delta 0.2%), AMD Ryzen 7 PRO 6850H (32,812, delta -0.2%), and AMD Ryzen AI 7 PRO 360 (32,662, delta 0.3%). These are all close competitors within a 0.5% band, confirming the Ryzen 5 7400F is a solid mid-range processor.

The GPU's nearest rivals are all significantly older parts. The ATI Mobility Radeon HD 5570 (1,186) is essentially tied with the Arc B370, differing by just 0.2%. The ATI Radeon HD 5770 (1,190) is 0.5% ahead, and the AMD Radeon HD 7650M (1,192) is 0.7% ahead. Only the AMD FirePro M2000 (1,168) sits behind, by 1.4%. These comparisons to early-2010s hardware illustrate just how limited the Arc B370 is for gaming.

In practical terms, this combo ranks below the vast majority of dedicated gaming setups. The 2,517th position out of 2,740 means roughly 92% of tested combinations perform better in Fortnite. The data suggests this pairing might be suitable for light gaming or as a general-purpose system, but it is not competitive for Fortnite beyond the lowest settings at 1080p.

Measured FPS Breakdown

1920x1080 (1080p):

• Low: 104 FPS average
• Medium: 73 FPS average (min 62, max 84)
• High: 57 FPS average
• Ultra: 37 FPS average

2560x1440 (1440p):

• Low: 66 FPS average
• Medium: 46 FPS average (min 39, max 53)
• High: 36 FPS average
• Ultra: 24 FPS average

3840x2160 (4K):

• Low: 35 FPS average
• Medium: 25 FPS average (min 21, max 28)
• High: 19 FPS average
• Ultra: 13 FPS average

The data reveals a consistent pattern across all resolutions: each settings tier costs roughly 30% of the previous tier's performance. At 1080p, dropping from Low to Medium costs 31 FPS (104 to 73), Medium to High costs 16 FPS, and High to Ultra costs 20 FPS. At 1440p, the progression is 66 to 46 to 36 to 24. At 4K, it's 35 to 25 to 19 to 13.

Only the Medium settings provide both minimum and maximum FPS measurements, and they show relatively tight ranges. At 1080p Medium, the spread is 62 to 84 FPS; at 1440p Medium, 39 to 53; at 4K Medium, 21 to 28. These ranges indicate consistent frame delivery without major stuttering, but the absolute performance ceiling is simply too low for demanding play.

The 4K results are particularly telling. Even at Low settings, the combo only manages 35 FPS, which is below the standard 60 FPS target. The gap between 1440p Low (66 FPS) and 4K Low (35 FPS) is 31 FPS, nearly identical to the 1080p Low to 1440p Low drop of 38 FPS. This linear scaling with pixel count confirms the GPU is the sole bottleneck, as a CPU-limited system would show diminishing FPS drops at higher resolutions rather than proportional ones.
