Fortnite

Fortnite, when paired with the AMD Ryzen 7 5700X and Intel Arc B370, presents a dataset that is heavily constrained by the graphics processor. The measured frames per second (FPS) across all resolutions and settings presets reveal a configuration where the CPU has significant headroom, but the integrated GPU becomes the primary bottleneck, particularly as resolution and graphical fidelity increase. The data indicates a playable experience primarily at 1080p with reduced settings, while higher resolutions and presets push the system into slideshow territory.

Resolution Scaling

The FPS drop from 1080p to 4K is steep and consistent across all settings presets, indicating that the Intel Arc B370 is the limiting component. At Low settings, the average FPS falls from 104 at 1920x1080 to 66 at 2560x1440, a reduction of 38 FPS, and then to 35 at 3840x2160, a further drop of 31 FPS. This is a classic sign of a GPU-bound scenario; the pixel throughput requirement scales geometrically, and the Arc B370's fillrate and shading capabilities are insufficient to maintain performance. The data suggests that the Arc B370's performance is halved when moving from 1080p to 1440p and then halved again moving to 4K at Low settings.

The trend is even more pronounced at higher presets. At High settings, the average FPS drops from 57 at 1080p to 36 at 1440p, and then to 19 at 4K. At Ultra settings, the numbers are 37, 24, and 13 respectively. This shows that the performance penalty for increasing resolution is not linear but exponential, which is expected when the rendering pipeline is saturated. The gap between Low and Ultra settings also widens with resolution, from a 67 FPS difference at 1080p to a 22 FPS difference at 4K, further emphasizing that the GPU is the primary constraint. The benchmark results indicate that the system is not CPU-limited at any tested resolution, as the relative performance drops are consistent with pure GPU workload scaling.

The implication is that for this specific hardware combo, the resolution is the single most dominant factor in determining playability. The CPU's performance headroom, evidenced by its benchmark scores, is irrelevant to the FPS in this game once the GPU is saturated. Users targeting 4K will find the experience unplayable across all settings, while 1440p is only marginally viable at Low settings. The sweet spot for this combination is strictly at 1920x1080, where the GPU can provide a frame rate that approaches acceptable levels for competitive play, but only with lower graphical presets.

FAQ

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

A: The measured data shows that 1920x1080 is the only resolution where the average FPS exceeds 100 on any preset. At 2560x1440, the maximum average FPS recorded is 66, and at 3840x2160, it is 35. Therefore, 1080p is the only viable resolution for a fluid experience.

Q: How does the game perform at Ultra settings?

A: The Ultra preset produces the lowest frame rates across all resolutions. The data shows an average of 37 FPS at 1080p, 24 FPS at 1440p, and 13 FPS at 4K. These results are all below the threshold for smooth gameplay, indicating that the Ultra preset is not feasible with this combo.

Q: Is the AMD Ryzen 7 5700X a bottleneck for the Intel Arc B370 in Fortnite?

A: No. The FPS scaling with resolution indicates a GPU bottleneck. The CPU's benchmark scores, such as a Cinebench R23 multi-core score of 13184 and a single-core score of 1499, are substantial. The fact that FPS drops significantly as resolution increases confirms the CPU is not the limiting factor in this game's tested scenarios.

Q: What is the performance difference between Low and Medium settings at 1080p?

A: At 1920x1080, the Low preset achieves an average of 104 FPS, while the Medium preset achieves an average of 73 FPS. This represents a 31 FPS difference. The Medium preset also has a measured minimum of 62 FPS and a maximum of 84 FPS, which are still within a playable range.

Q: How does the combo rank among other tested combinations?

A: The combo ranks 2517 out of 2740 tested combinations for Fortnite. This places it in the bottom 8% of all recorded configurations, indicating that its overall performance is below the vast majority of other tested systems.

Q: Does the Intel Arc B370 have enough memory for Fortnite?

A: The GPU uses "System Shared" memory, meaning its memory size and bandwidth are dependent on the system's RAM. The data does not provide a specific VRAM capacity. The performance numbers, however, suggest that the shared memory configuration is not sufficient for high-resolution or high-detail rendering, given the low FPS at 1440p and 4K.

CPU Role

The AMD Ryzen 7 5700X is a Zen 3 architecture processor with 8 cores and 16 threads. Its base clock is 3.40 GHz and it boosts up to 4.60 GHz. The CPU's benchmark data shows it is a capable processor, with a 3DMark max threads score of 6850, a Cinebench R23 multi-core score of 13184, and a single-core score of 1499. It holds a 79th percentile ranking among all CPUs, and its average benchmark score of 27578 is on par with the Intel Core i5-12600K, which has a 0% delta. This suggests that the CPU is not a weak link in the system.

In the context of Fortnite, the game's performance is typically sensitive to single-core speed, but the data here shows that the GPU is the bottleneck. The measured FPS does not improve when the resolution is lowered, which would be the expected behavior if the CPU were the limiting factor. Instead, we see FPS scaling inversely with resolution, which is a hallmark of a GPU-bound workload. The CPU's role is to feed the GPU with draw calls and game logic, and its 16 threads provide ample parallel processing power for this task.

The data indicates that the Ryzen 7 5700X has significant headroom in this specific configuration. Even at 1080p Low settings, where the average FPS is 104, the GPU is likely still the constraining factor, as the CPU has the single-thread performance (PassMark single-thread score of 3385) to handle the game's logic at higher frame rates. The fact that the frame rate drops to 57 at High settings at the same resolution is a direct result of the GPU struggling with the increased graphical load, not the CPU. Therefore, any performance improvements for this combo in Fortnite would require a more powerful GPU, not a CPU upgrade.

Measured FPS Breakdown

The dataset provides average FPS for three resolutions and four settings presets, with some entries also recording minimum and maximum FPS.

1920x1080:

At this resolution, the performance range is broad. The Low preset delivers the highest average FPS at 104. The Medium preset averages 73 FPS, with a recorded minimum of 62 and a maximum of 84. The High preset averages 57 FPS. The Ultra preset is the weakest, averaging only 37 FPS.

2560x1440:

Performance drops significantly at this resolution. The Low preset averages 66 FPS, which is the only playable result here. The Medium preset averages 46 FPS, with a minimum of 39 and a maximum of 53. The High preset averages 36 FPS. The Ultra preset averages 24 FPS.

3840x2160:

At 4K, the game is not playable. The Low preset averages 35 FPS. The Medium preset averages 25 FPS, with a minimum of 21 and a maximum of 28. The High preset averages 19 FPS. The Ultra preset averages 13 FPS, which is the lowest score in the entire dataset.

The data shows a clear pattern: the combination of resolution and settings determines the experience. The only scenario that yields an average FPS above 100 is 1080p Low. The only other scenario that consistently stays above 60 FPS is 1440p Low. All other configurations result in average frame rates below 60 FPS, which will be noticeable as stuttering and lag in a fast-paced game like Fortnite.

How This Combo Ranks

The AMD Ryzen 7 5700X and Intel Arc B370 combination ranks 2517 out of 2740 tested combos for Fortnite. This places it in the bottom 8.2% of all recorded systems. This low ranking is almost entirely attributable to the Intel Arc B370's performance, which has a percentile ranking of 5 among all GPUs. The GPU's average benchmark score is 1184, which is comparable to the ATI Mobility Radeon HD 5570 (deltaPct -0.2%) and the ATI Radeon HD 5770 (deltaPct -0.5%).

This ranking is a quantitative summary of the FPS data. It confirms that this configuration is not competitive for Fortnite. The CPU, while ranking in the 79th percentile, cannot compensate for the GPU's lack of rendering power. The nearest rival CPUs, such as the AMD Ryzen 7 5800 (deltaPct 0.2%) and the Intel Core Ultra 5 125H (deltaPct 0.3%), have similar average benchmark scores, but they do not have the same GPU bottleneck. The data suggests that this specific pairing is highly unbalanced, with the GPU holding back the system's overall gaming potential.

Settings Recommendations

Based on the measured FPS data, the only configuration that provides a consistently smooth experience is the Low preset at 1920x1080, which achieves an average of 104 FPS. This is the only setting and resolution combination that exceeds the 100 FPS mark, which is often desirable for competitive shooters.

The Medium preset at 1920x1080 is the next best option, with an average of 73 FPS. The recorded minimum of 62 FPS ensures that frame drops are less likely to be severe, making this a viable alternative for users who prioritize visual quality over maximum frame rate. The 73 FPS average is still within the range of smooth gameplay, though it is a 30% reduction from the Low preset.

For users who insist on 1440p, the Low preset at 2560x1440 is the only option that yields an average above 60 FPS (66 FPS). However, this comes at a significant visual compromise. All other presets at 1440p, and all presets at 4K, result in average frame rates below 50 FPS, which is not recommended for a game that requires quick reactions. The data does not support using High or Ultra presets at any resolution, as they all result in average frame rates below 60 FPS, with Ultra at 1080p being the only one to reach 37 FPS.

GPU Role

The Intel Arc B370 is the primary subject of this analysis, and its performance is the decisive factor in the measured results. It is an integrated GPU (IGP) based on the Xe3-LPG architecture and built on a 3 nm process node. It has 1280 shading units, 40 texture mapping units (TMUs), and 20 render output units (ROPs). Its boost clock is 2400 MHz, and it has 10 ray tracing cores. The GPU's theoretical performance is 6.144 TFLOPS for FP32 operations and 12.29 TFLOPS for FP16 operations. It has a TDP of 25 W.

Crucially, the GPU uses "System Shared" memory, meaning it relies on the system's main RAM for its memory pool. This is a significant factor in its performance. The memory bandwidth is listed as "System Dependent," which means it is constrained by the system's memory configuration and motherboard design. This shared memory architecture is a major bottleneck in a game like Fortnite, which requires high bandwidth for texture streaming and geometry data.

The GPU's benchmark results are poor, with a 3DMark Steel Nomad DX12 score of 1184, placing it in the 5th percentile of all GPUs. Its nearest rivals are all older, low-end components like the ATI Radeon HD 5770 (deltaPct -0.5%). This explains the FPS data. At 1080p Low, which is a low-fill-rate workload, the GPU can manage 104 FPS. However, as the resolution and settings increase, the demand for pixel shading, texture filtering, and memory bandwidth overwhelms the GPU's limited resources, causing the FPS to plummet. The data indicates that this GPU is only suitable for light gaming at low resolutions and settings, and it is not designed for demanding titles like Fortnite at high fidelity.
