Fortnite

The AMD Ryzen 7 7700 paired with the Intel Arc B390 presents a highly unbalanced performance profile in Fortnite. The data shows a CPU that is exceptionally strong sitting alongside a GPU that ranks in the lowest percentile of all tested graphics cards. This combination results in a system where the graphics processor is the definitive bottleneck, limiting the experience to low frame rates even at 1080p, while the central processor remains largely underutilized. This analysis breaks down the measured FPS data to illustrate how this pairing behaves across resolutions and settings, and what users can expect from this specific configuration.

Resolution Scaling

The measured FPS data clearly demonstrates that the Intel Arc B390 is the limiting component in this system, with performance collapsing as resolution increases. At 1080p with Low settings, the combo achieves an average of 115 FPS. Moving to 1440p at the same settings drops the average to 73 FPS, a reduction of 42 FPS. At 4K, the average plummets to 39 FPS, which is just over a third of the 1080p result.

This scaling pattern is characteristic of a GPU-bound scenario. If the CPU were the primary constraint, the frame rate would remain relatively flat across resolutions, as the processor's workload does not change significantly with pixel count. Here, the steep decline in performance from 1080p to 4K indicates that the Intel Arc B390's rendering capabilities are being saturated, and it cannot keep up with the increasing pixel output demand.

The trend holds across other settings. With High settings, the average FPS falls from 63 at 1080p to 40 at 1440p, and then to 21 at 4K. The Ultra preset shows the most dramatic decline, going from an average of 41 FPS at 1080p to 26 FPS at 1440p and finally to a mere 14 FPS at 4K. The consistency of this pattern across all presets confirms that the GPU's fill rate and shader processing power are the primary determinants of frame rate in this configuration. The Ryzen 7 7700, with its 8 cores and 16 threads, is not the constraint; it has ample headroom to feed the GPU, but the GPU cannot process the frames fast enough.

How This Combo Ranks

Within the benchmark database, this specific combination of the AMD Ryzen 7 7700 and the Intel Arc B390 ranks 2417th out of 2740 tested combos for Fortnite. This places the pairing in the bottom 12% of all configurations, highlighting that it is a low-performing option for this specific game.

The ranking is heavily influenced by the GPU's weak standing. The Intel Arc B390 has a percentileVsAllGpus score of 9, meaning it performs better than only 9% of all tested graphics cards. Its average benchmark score is just 1482, and its nearest rivals in the GPU benchmark charts are the NVIDIA GeForce GT 520MX, NVIDIA GeForce 800M, NVIDIA GeForce GT 625 OEM, and NVIDIA GeForce GT 710. These are all very old, low-end graphics solutions, and the Arc B390 is in the same performance tier as them. This positions the GPU as a significant handicap for the system.

In contrast, the CPU is a top-tier performer. The AMD Ryzen 7 7700 has a percentileVsAllCpus of 87, outperforming 87% of all tested CPUs. Its average benchmark score is 40081, and it sits in a tight group with rivals like the AMD Ryzen AI 9 365 and Intel Core 5 221E, with a performance delta of only a few tenths of a percent. This shows that the processor is more than capable of handling modern games, making the low combo rank almost entirely attributable to the graphics card.

GPU Role

The Intel Arc B390 is the decisive factor in this system's Fortnite performance, and the data suggests it is fundamentally unsuited for this game. The GPU's benchmark results are stark, with its only recorded 3DMark Steel Nomad DX12 score being 1482. This places it in the 9th percentile of all GPUs, a clear indication of its limited computational power.

The card's specifications support this finding. It has 1536 shading units, 48 texture mapping units, and 24 raster output pipelines. Its FP32 performance is rated at 7.680 TFLOPS. These are low numbers for a modern discrete GPU, and in this case, the card is an integrated graphics processor (IGP) with a system-shared memory configuration. The memory size, type, and bus width are all listed as "System Shared," and the bandwidth is "System Dependent," meaning it relies on the system's main memory, which is a significant bottleneck.

The GPU's clock speeds, with a base of 300 MHz and a boost of 2500 MHz, cannot compensate for the low core counts and shared memory architecture. The measured results show this clearly: at 4K Ultra settings, the average FPS is just 14. Even at 1080p Low, the average FPS is 115, which is acceptable but not high, and this is the best-case scenario. The GPU's 80W TDP and IGP slot width confirm its position as a low-power, entry-level solution rather than a performance gaming part.

Settings Recommendations

Given the GPU's constraints, the measured data points to a single viable path for playable frame rates. The only configuration that consistently approaches a playable 60 FPS is 1080p with Low settings, which averages 115 FPS. This is the only preset at 1080p that provides a comfortable margin above 60 FPS.

The Medium preset at 1080p yields an average of 81 FPS, but with minimums that can dip to 69 FPS. While this is still technically playable, the drop from Low to Medium comes with a significant cost. The High preset at 1080p drops the average to 63 FPS, and the Ultra preset brings it down to 41 FPS.

At 1440p, the performance is considerably worse. The Low preset averages 73 FPS, but the Medium preset drops to 51 FPS with a minimum of 44 FPS. The High and Ultra presets are not recommended, with averages of 40 FPS and 26 FPS, respectively. At 4K, the results are mostly unplayable, with the Low preset being the only option above 30 FPS, averaging 39 FPS. The Ultra preset at 4K is the worst case, with an average of just 14 FPS.

For the best experience according to the measured rows, the recommendation is clear: use 1080p with the Low preset. This is the only combination that provides a high and stable frame rate. Users who prioritize visual quality over performance could consider the Medium preset at 1080p, but they must accept the lower average and minimum FPS. Any other setting or resolution combination leads to a suboptimal experience.

CPU Role

The AMD Ryzen 7 7700 is a high-end desktop processor that provides more than enough computational power for Fortnite, but its performance is completely masked by the weak GPU. The CPU has 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. Its benchmark results confirm its strength, with a Cinebench R23 multicore score of 18760 and a single-core score of 1930.

In the context of this benchmark, the CPU's role is to feed the GPU with draw calls and game logic. The data suggests that the Ryzen 7 7700 is never the limiting factor. For example, at 1080p Low, the combo achieves 115 FPS. If the CPU were weak, we would expect frame rates to be similar across different resolutions, as the CPU's workload would be the same. Instead, we see a sharp decline in FPS as resolution increases, which is the signature of a GPU bottleneck.

The CPU's percentileVsAllCpus of 87 and its performance parity with rivals like the AMD Ryzen AI 9 365 and Intel Core 5 221E (with a delta of only 0.1% and -0.2%, respectively) further demonstrate its capability. This processor is not the issue. In a system with a more powerful GPU, the Ryzen 7 7700 would likely be able to deliver significantly higher frame rates. As it stands, the system's performance is capped by the Intel Arc B390, and the CPU's potential is left on the table.

The data reveals a linear progression of performance loss. For the Low preset, moving from 1080p to 1440p reduces the average FPS by 42, and moving from 1440p to 4K reduces it by another 34. For the High preset, the drop from 1080p to 1440p is 23 FPS, and from 1440p to 4K is 19 FPS. The Medium preset shows a similar trend, with a 30 FPS drop from 1080p to 1440p and a 24 FPS drop from 1440p to 4K.

The Ultra preset at 4K produces an average of 14 FPS, which is the lowest measured result. Notably, the Medium preset is the only one with min and max FPS data provided, showing a range of 69-93 FPS at 1080p, 44-59 FPS at 1440p, and 23-31 FPS at 4K. This provides a clear picture of the frame time variance. In all cases, the average FPS figures are the primary metric, and they consistently show that this combo is only suitable for 1080p gaming at the lowest settings.
