Microsoft Flight Simulator

Microsoft Flight Simulator is a demanding title that scales heavily with both resolution and graphical presets, and the measured results for the AMD Ryzen 9 7900X paired with the Intel Arc B580 provide a clear picture of this pairing's capabilities. The data shows a consistent and predictable pattern: as resolution increases from 1920x1080 to 3840x2160, average frame rates drop substantially across all settings, revealing where the performance bottleneck lies for this specific combination of hardware.

Resolution Scaling

The FPS drop from 1080p to 4K is significant and tells a clear story about the limiting component. At Low settings, the average frame rate falls from 94.1 FPS at 1920x1080 to 79.1 FPS at 2560x1440, and finally to 56.6 FPS at 3840x2160. This represents a 40% reduction in performance from the lowest to the highest resolution tested. The pattern holds for Medium settings, where the average drops from 75.2 FPS at 1080p to 62.7 FPS at 1440p, and then to 42.8 FPS at 4K — a 43% decrease overall.

The scaling becomes even more pronounced at higher presets. High settings see averages of 59.0 FPS at 1080p, 47.8 FPS at 1440p, and 31.1 FPS at 4K, which is a 47% drop from 1080p to 4K. Ultra settings follow suit, with 57.1 FPS at 1080p, 45.3 FPS at 1440p, and 29.3 FPS at 4K, a 49% reduction. The widening gap between resolutions as settings increase indicates that the Intel Arc B580 is the primary constraint at higher resolutions, as the GPU must work progressively harder to fill the larger pixel counts. At 1080p, the frame rates remain relatively high, suggesting the CPU has more headroom, but the GPU becomes the limiting factor as pixel count rises.

GPU Role

The Intel Arc B580 brings 12 GB of GDDR6 memory on a 192-bit bus, yielding a bandwidth of 456.0 GB/s. This memory configuration is relevant for Microsoft Flight Simulator, which streams large amounts of terrain and scenery data. The GPU's base and boost clocks are both locked at 2670 MHz, and its 2560 shading units deliver a pixel rate of 213.6 GPixel/s and a texture rate of 427.2 GTexel/s. These specifications translate into a passmark G3D score of 15748, placing the GPU in the 66th percentile of all GPUs.

The benchmark results show that the GPU's performance is adequate for 1080p gaming but struggles to maintain playable frame rates at 4K with higher presets. At Ultra settings, the average FPS at 3840x2160 is 29.3, which is barely above the threshold for smooth gameplay. The GPU's nearest rivals in the benchmark database include the NVIDIA GeForce RTX 4060, which scores 23181 on average, just 0.7% higher than the B580's average of 23021. This close margin indicates that the Arc B580 performs similarly to a mainstream competitor, but the data confirms it is not a high-end solution for 4K gaming in this title. The GPU's TDP of 190 W and its PCIe 4.0 x8 interface suggest it is designed for mainstream builds rather than extreme performance.

CPU Role

The AMD Ryzen 9 7900X is a 12-core, 24-thread processor based on the Zen 4 architecture, with a base clock of 4.70 GHz and a boost clock of 5.60 GHz. Its 64 MB of shared L3 cache and dual-channel DDR5 memory support with 83.2 GB/s of bandwidth provide ample resources for the simulation's complex physics and AI computations. The CPU scores 43695 in Cinebench R23 multicore and 6168 in single-core, with an average benchmark score of 50556, placing it in the 93rd percentile of all CPUs.

In this pairing, the CPU appears to be less of a bottleneck than the GPU, particularly at lower resolutions. At 1920x1080 with Low settings, the average FPS of 94.1 indicates that the Ryzen 9 7900X can feed frames quickly enough to keep the GPU busy. The 3DMark single-thread score of 1093 and the 3DMark 16-thread score of 10972 show strong performance across both single and multi-threaded workloads, which is beneficial for a game that uses multiple cores for scenery generation. The CPU's nearest rivals include the Intel Core i9-13980HX, which scores 50944 on average, just 0.8% higher, and the AMD Ryzen 9 5900XT at 50738, 0.4% higher. These marginal differences mean the 7900X is on par with other high-end processors, and the data suggests it is not the primary limiting factor in most scenarios tested.

How This Combo Ranks

Within the benchmark database, this specific combination of the Ryzen 9 7900X and the Arc B580 ranks 1385 out of 1795 tested combos for Microsoft Flight Simulator. This ranking places it in the lower-middle portion of all configurations, which aligns with the GPU's mid-range standing. The CPU's high percentile (93rd) is offset by the GPU's more modest percentile (66th), resulting in a combo that performs adequately but not exceptionally.

The rank of 1385 suggests that while the CPU is powerful, the GPU holds the overall combo back in this gaming workload. For comparison, the GPU's nearest rival, the RTX 4060, would likely produce a slightly higher ranking given its marginally better average score, but the difference is small. The data indicates that this combo is better suited for 1080p and 1440p gaming rather than 4K, where the GPU's limitations become apparent. Users with this pairing should expect a balanced experience at mainstream resolutions, but they will need to lower settings to achieve playable frame rates at 4K.

Settings Recommendations

Based on the measured FPS values, the optimal settings for this combo depend on the target resolution. At 1920x1080, the High preset delivers 59.0 FPS, which is smooth for most players, and the Ultra preset only drops to 57.1 FPS, making it a viable option for those who prioritize visual fidelity. The Medium preset at 75.2 FPS offers a good balance if higher frame rates are desired, but the jump from Medium to High is only 13.8 FPS, while High to Ultra is a mere 1.9 FPS, suggesting Ultra is nearly free at 1080p.

At 2560x1440, the High preset provides 47.8 FPS, which is playable but not ideal for fast-paced action. The Medium preset at 62.7 FPS is a better recommendation for smoother gameplay, as it offers a 31% improvement over High. The Ultra preset drops to 45.3 FPS, which is below the comfort threshold for many users. At 3840x2160, the Medium preset yields 42.8 FPS, which is the highest playable setting, while High and Ultra fall to 31.1 and 29.3 FPS respectively, making them unsuitable for consistent gameplay. The Low preset at 56.6 FPS is the only 4K option that clears the 60 FPS target, but it sacrifices significant visual quality.

Measured FPS Breakdown

At 1920x1080, the average FPS across settings is 94.1 at Low, 75.2 at Medium, 59.0 at High, and 57.1 at Ultra. The performance difference between Low and Ultra is 37.0 FPS, representing a 39% reduction. At 2560x1440, the averages are 79.1 at Low, 62.7 at Medium, 47.8 at High, and 45.3 at Ultra, with a 33.8 FPS difference between Low and Ultra. At 3840x2160, the averages are 56.6 at Low, 42.8 at Medium, 31.1 at High, and 29.3 at Ultra, with a 27.3 FPS difference between Low and Ultra.

The data shows that the scaling from Low to Ultra is more pronounced at lower resolutions in absolute terms, but the relative percentage drop is similar across all resolutions. For instance, at 1080p, Ultra is 39% slower than Low, while at 4K, Ultra is 48% slower. This indicates that the GPU's workload increases disproportionately at higher resolutions and settings, reinforcing the conclusion that the Arc B580 is the limiting component. The minimum and maximum FPS values are not provided, but the average FPS figures are sufficient to characterize the performance envelope for this configuration.
