Fortnite

The AMD Ryzen 7 7700 paired with the Intel Arc B370 produces a highly constrained gaming experience in Fortnite. The data indicates that this combination is severely limited by the graphics processor, resulting in frame rates that are generally below competitive thresholds at most resolutions and settings. The Arc B370 operates as an integrated graphics part with system-shared memory, which fundamentally shapes the performance profile observed in the measured rows.

Resolution Scaling

The resolution scaling behavior of this combo is stark. Moving from 1920x1080 to 2560x1440 and then to 3840x2160 shows a consistent and substantial performance penalty at every settings level. At Low settings, the average frame rate drops from 104 FPS at 1080p to 66 FPS at 1440p, a reduction of 38 FPS. Scaling further to 4K at Low settings yields an average of only 35 FPS, which is less than one-third of the 1080p result. This pattern indicates that the rendering pipeline is heavily pixel-bound, with the integrated GPU struggling to maintain throughput as the pixel count increases.

At Medium settings, the same trend is visible: 73 FPS at 1080p, 46 FPS at 1440p, and 25 FPS at 4K. The proportional drop from 1080p to 1440p is approximately 37%, which is slightly larger than the drop seen at Low settings, suggesting that the additional shading work at Medium settings compounds the resolution pressure. High settings follow a similar trajectory, with 57 FPS at 1080p, 36 FPS at 1440p, and 19 FPS at 4K. The 4K High result is below playable thresholds for most users, indicating that this resolution is not viable for this combo outside of the absolute lowest setting.

The scaling from 1080p to 4K at Ultra settings is particularly revealing. The average frame rate plummets from 37 FPS at 1080p to 24 FPS at 1440p and finally to 13 FPS at 4K. The fact that even 1080p Ultra only achieves 37 FPS demonstrates that the GPU is the primary limiting factor, as the CPU is not being saturated at these low frame rates. The data suggests that the integrated graphics unit has a hard ceiling around 104 FPS at 1080p Low, and every increase in resolution or graphical fidelity directly subtracts from that ceiling. This is a classic signature of a GPU-bound scenario where the system memory bandwidth and execution units of the Arc B370 are the constraining resources.

GPU Role

The Intel Arc B370 is the decisive component in this pairing. Its specifications paint a clear picture of an entry-level integrated solution: 1280 shading units, 40 texture mapping units, and 20 render output units. The boost clock of 2400 MHz provides the theoretical peak, but the memory configuration is "System Shared" with "System Dependent" bandwidth, which means performance is tied to the host system's memory speed and allocation. The GPU's TDP is a mere 25 W, reinforcing its role as a low-power integrated part rather than a discrete solution.

The benchmark results for the GPU confirm its position. In 3DMark Steel Nomad DX12, it scores 1184 points, which places it in the 5th percentile of all GPUs. Its nearest rivals in the database are older parts like the ATI Mobility Radeon HD 5570, which scores 1186, and the ATI Radeon HD 5770, which scores 1190. The delta percentages are negligible, with the Arc B370 trailing the HD 5570 by 0.2% and the HD 5770 by 0.5%. This places the Arc B370 in the same performance tier as graphics hardware from over a decade ago, which directly explains the Fortnite frame rates observed.

The GPU's 6.144 TFLOPS of FP32 compute is theoretically adequate for light workloads, but the shared memory architecture creates a bottleneck. In Fortnite, a game that relies heavily on draw calls and texture streaming, the system-shared memory bandwidth becomes the limiting factor. The measured FPS data supports this: at 1080p Low, the combo reaches 104 FPS, which is likely near the practical limit for this memory subsystem. At higher settings, the increased texture and geometry complexity saturates the available bandwidth, causing the steep drops to 73 FPS at Medium and 57 FPS at High. The 4K results, ranging from 35 FPS at Low to 13 FPS at Ultra, demonstrate that the GPU cannot maintain even basic playability at that resolution, regardless of how much the CPU is capable of.

Settings Recommendations

Given the measured data, the optimal settings for this combo depend heavily on the target resolution and desired frame rate. For 1920x1080, the Low preset delivers an average of 104 FPS, which is the only configuration that approaches a high-refresh experience. Medium settings at 1080p yield 73 FPS, which is still playable for most users, but High drops to 57 FPS, and Ultra falls to 37 FPS. The data suggests that 1080p Low is the only setting that allows the hardware to stretch its legs, while Medium provides a reasonable balance for users who prioritize visual quality over raw speed.

At 2560x1440, the options become more limited. Low settings produce 66 FPS, which is acceptable for casual play, but Medium drops to 46 FPS, and High falls to 36 FPS. Ultra at 1440p is effectively unplayable at 24 FPS. For 4K, the only remotely viable setting is Low at 35 FPS, which is below the 60 FPS threshold that most players consider smooth. Medium at 4K drops to 25 FPS, and High and Ultra are in single-digit-to-low-20s territory.

The recommendation based on the measured rows is to use Low settings at 1080p for the best experience, as this is the only configuration that breaks the 100 FPS barrier. For users who must play at 1440p, Low is the only sensible choice, as it maintains 66 FPS. Users with 4K displays should either lower the resolution or accept that the game will run at sub-30 FPS, as the data unequivocally shows that this GPU cannot handle 4K Fortnite with any degree of fluidity. The Medium preset at 1080p offers a compromise, but the 31 FPS penalty compared to Low is steep, suggesting that the visual improvements do not justify the performance cost on this hardware.

Measured FPS Breakdown

The measured FPS data provides a comprehensive look at the combo's capabilities across twelve configurations. At 1920x1080, the results are as follows: Low averages 104 FPS, Medium averages 73 FPS with a minimum of 62 and maximum of 84, High averages 57 FPS, and Ultra averages 37 FPS. The variance at Medium indicates some frame time instability, but the averages are consistent with the expected scaling.

At 2560x1440, the performance curve shifts downward. Low averages 66 FPS, Medium averages 46 FPS with a minimum of 39 and maximum of 53, High averages 36 FPS, and Ultra averages 24 FPS. The Medium preset at 1440p shows a tighter range than at 1080p, suggesting that the GPU is hitting its limits more consistently.

At 3840x2160, the results are marginal. Low averages 35 FPS, Medium averages 25 FPS with a minimum of 21 and maximum of 28, High averages 19 FPS, and Ultra averages 13 FPS. The 4K Medium range is narrow, indicating that the GPU is fully saturated and cannot handle any scene complexity beyond its baseline. The 13 FPS at Ultra is effectively a slideshow, confirming that 4K Ultra is not a viable option.

CPU Role

The AMD Ryzen 7 7700 is a high-end desktop processor that is significantly overpowered relative to the Intel Arc B370 GPU in this configuration. The CPU features 8 cores and 16 threads based on the Zen 4 architecture, with a base clock of 3.80 GHz and a boost clock of 5.30 GHz. It supports DDR5 memory with dual-channel bandwidth of 83.2 GB/s, and its L3 cache is 32 MB shared. The CPU's benchmark scores are robust: it achieves 18760 in Cinebench R23 multicore and 1930 in single-core, and it scores 2525 in Geekbench single-core. Its average benchmark score is 40081, placing it in the 87th percentile of all CPUs.

The nearest rival CPUs include the AMD Ryzen AI 9 365 with an average score of 40048 (0.1% slower), the Intel Core 5 221E with 40144 (0.2% faster), and the AMD Ryzen 9 270 with 40246 (0.4% faster). These deltas are negligible, indicating that the 7700 sits in a tight performance bracket. In Fortnite, however, this CPU power is largely unused. At 1080p Low, the GPU is already at its limit at 104 FPS, and the CPU is nowhere near saturation. The measured frame rates scale almost entirely with GPU load, not CPU load, confirming that the 7700 is not a bottleneck in any scenario presented in the data.

The CPU's high single-thread performance, as evidenced by its 1930 Cinebench R23 single-core score, would normally be beneficial for Fortnite's game logic and physics. However, the GPU's inability to render frames quickly enough means that the CPU spends most of its time idle. The only scenario where the CPU might matter is at 1080p Low, where the 104 FPS average suggests the system is pushing toward a balance, but even then, the GPU's shared memory architecture is likely the limiting factor. The 7700's 65 W TDP and 5 nm process node make it an efficient part, but efficiency does not translate to higher FPS when the GPU is this weak.

How This Combo Ranks

In the benchmark database, this specific combination of the AMD Ryzen 7 7700 and Intel Arc B370 ranks 2517 out of 2740 tested combos for Fortnite. This places it in the bottom 8% of all configurations, which aligns with the measured frame rates. The rank reflects the GPU's severe limitation, as the CPU's strong performance cannot compensate for the integrated graphics part's low throughput.

The combo's rank is a direct consequence of the Arc B370's position in the GPU hierarchy. With a percentile rank of 5 among all GPUs, the Arc B370 is in the bottom 5% of graphics hardware. Even a mid-range CPU like the Ryzen 7 7700, which sits in the 87th percentile, cannot lift the combo's overall ranking. The data shows that combos with discrete GPUs, even older ones, would likely rank significantly higher due to the dedicated memory bandwidth and higher compute throughput.

The rank of 2517 out of 2740 suggests that there are only 223 combos that perform worse than this one, which is a stark indicator of the Arc B370's limitations. For a game like Fortnite, which is known for being well-optimized and capable of running on modest hardware, this rank is particularly notable. It implies that almost any discrete GPU from the last decade would provide a better experience than this integrated solution. The combo's performance is consistent with its rank: it can barely manage 60 FPS at 1080p Low, and it fails to reach 30 FPS at 4K on any setting. The conclusion from the ranking data is that this is a pairing for low-end, low-resolution gaming, not for competitive or high-fidelity play.
