Microsoft Flight Simulator

The AMD Ryzen 7 5800XT and Intel Arc B580 pairing presents a clear performance hierarchy in Microsoft Flight Simulator, with resolution acting as the primary governor of frame rates. At 1080p with Low settings, the combo achieves 96.4 FPS, which drops to 76.4 FPS at 1440p and 56 FPS at 4K. This scaling pattern—a 20 FPS loss from 1080p to 1440p and another 20.4 FPS loss to 4K—indicates that the graphics card becomes increasingly dominant as pixel count rises. The gap between Low and Ultra settings widens dramatically at higher resolutions: at 1080p, the spread is 42 FPS (96.4 to 54.4), while at 4K it narrows to 22.9 FPS (56 to 33.1). This compression suggests that at 4K, the Arc B580 is nearing its throughput ceiling, making the CPU’s role less consequential for maximum frame rates.

Resolution Scaling

The measured data reveals a steep performance curve across the three tested resolutions. At 1080p, the system shows strong headroom, with Low settings hitting 96.4 FPS and Medium at 74.5 FPS. However, the transition to 1440p exacts a significant toll: High settings fall from 54.5 FPS to 43.1 FPS, a 21% reduction, while Ultra drops from 54.4 FPS to 44.1 FPS. The 4K results confirm the GPU-bound nature of this pairing—Ultra manages just 33.1 FPS, and even Low settings only reach 56 FPS. The data shows that 1440p is the practical ceiling for playable frame rates with this combo, provided settings are kept below Ultra. The scaling from 1440p to 4K is particularly steep for Medium settings, which drop from 62.8 FPS to 42.8 FPS, a 31.8% decrease. This nonlinear behavior indicates that memory bandwidth and pixel throughput become limiting factors beyond 1440p, as the Arc B580’s 456.0 GB/s bandwidth and 213.6 GPixel/s pixel rate are taxed heavily by the simulator’s dense terrain rendering.

Settings Recommendations

For users prioritizing smoothness, the Low preset at 1080p delivers the highest measured average at 96.4 FPS, but this sacrifices visual fidelity in a game where scenery detail is central to the experience. The Medium preset at 1440p offers a more balanced compromise: 62.8 FPS, which remains above the 60 FPS threshold for most monitors. At 4K, no preset achieves 60 FPS; the best option is Low at 56 FPS, which is marginally playable but requires significant visual compromises. The High preset at 1080p (54.5 FPS) and Ultra at 1080p (54.4 FPS) are nearly identical in performance, suggesting that the game’s Ultra settings add minimal overhead at this resolution—likely due to CPU-side bottlenecks in draw call processing. Conversely, at 1440p, Ultra (44.1 FPS) trails High (43.1 FPS) by only 1 FPS, indicating that the GPU is the binding constraint. The optimal experience per the measured rows is Medium at 1440p, which provides 62.8 FPS while retaining moderate detail levels; stepping up to High at 1440p sacrifices nearly 20 FPS for marginal visual gains. For 4K users, Low is the only viable preset, as Medium (42.8 FPS) and High (35.9 FPS) fall below acceptable smoothness thresholds.

GPU Role

The Intel Arc B580’s specifications directly shape these results. With 12 GB of GDDR6 memory on a 192-bit bus, the card delivers 456.0 GB/s of bandwidth—sufficient for 1080p and 1440p workloads but strained at 4K where texture streaming demands increase. The GPU’s 2560 shading units and 80 ROPs produce a pixel rate of 213.6 GPixel/s, which explains the sharp drop between 1440p and 4K: at 4K, the pixel count quadruples from 1080p, yet the card’s throughput cannot scale accordingly. The boost clock of 2670 MHz is consistent across base and boost, indicating a fixed operating point that doesn’t provide additional headroom under load. The card’s 13.67 TFLOPS FP32 performance places it in a mid-range tier, as evidenced by its 66th percentile ranking among all GPUs. In game-specific terms, the 4K Ultra result of 33.1 FPS shows that the Arc B580 lacks the raw compute to handle this simulator’s highest settings at high resolution. The 20 RT cores and DirectX 12 Ultimate support are present but do not meaningfully influence these average FPS figures, as Microsoft Flight Simulator’s rendering workload is primarily rasterization-based. The 12 GB frame buffer prevents capacity-related stuttering even at 4K Ultra, but the card’s memory bandwidth (456.0 GB/s) becomes the limiting factor, as evidenced by the disproportionate FPS drops at higher resolutions.

How This Combo Ranks

In the comprehensive benchmark database, this CPU-GPU pairing ranks 1401st out of 1795 tested combos for Microsoft Flight Simulator, placing it in the lower 22% of configurations. This ranking reflects the GPU’s mid-tier standing rather than the CPU’s capabilities—the Ryzen 7 5800XT holds an 86th percentile ranking among all CPUs, while the Arc B580 sits at the 66th percentile among GPUs. The combo’s position suggests that pairing this processor with a stronger graphics card would yield substantially better results, as the CPU’s 3DMark max-thread score of 7680 indicates ample headroom for higher frame rates. The measured FPS data supports this: at 1080p Low, the system reaches 96.4 FPS, but this is likely constrained by the GPU’s driver overhead and rasterization limits rather than the CPU. The ranking also implies that many competing combinations with less powerful CPUs but stronger GPUs achieve better scores in this title, which is consistent with the game’s known GPU-heavy nature. For users with this combo, the data suggests that the 5800XT is not the bottleneck—the Arc B580’s 13.67 TFLOPS and 66th percentile standing are the limiting factors in achieving higher rankings.

CPU Role

The AMD Ryzen 7 5800XT contributes 8 cores and 16 threads based on the Zen 3 architecture, with a base clock of 3.80 GHz and boost clock of 4.80 GHz. In Microsoft Flight Simulator, which relies heavily on single-thread performance for game logic and physics, the CPU’s single-thread benchmarks are telling: a 3DMark single-thread score of 959 and Cinebench R23 single-core score of 3359. These figures indicate strong per-core performance that should prevent CPU-bound scenarios at lower resolutions. However, the data shows that at 1080p, the FPS difference between Low (96.4) and Ultra (54.4) is substantial, implying that the GPU is still the primary limiter even at the lowest resolution. The CPU’s 32 MB of L3 cache and 51.2 GB/s memory bandwidth are adequate for feeding the GPU, but the game’s complex scenery streaming benefits from the 8-core layout, as evidenced by the Cinebench R23 multicore score of 23794. The fact that the 5800XT’s nearest rivals in synthetic benchmarks—including the AMD Ryzen 7 PRO 5755GE (0.1% faster average score) and AMD Ryzen AI 7 PRO 360 (0.3% slower)—show negligible differences suggests that CPU choice among similarly performing chips will not meaningfully alter FPS in this title. Instead, the data points to the GPU as the decisive component: the Arc B580’s 66th percentile ranking aligns with the combo’s low overall rank, confirming that CPU-side upgrades would yield diminishing returns for this specific pairing.
