Microsoft Flight Simulator

Microsoft Flight Simulator is a demanding title that stresses both the CPU and GPU heavily, and the measured data for the AMD Ryzen 5 7400F paired with the AMD Radeon RX 7800 XT provides a clear picture of how this combination scales across resolutions and settings. The benchmark results show a system that is capable of smooth gameplay at lower settings but begins to show its limits as graphical fidelity and pixel count increase, with the frame rate dropping from a highly playable 149 FPS at 1080p Low to a borderline 49 FPS at 4K Ultra.

Resolution Scaling

The frame rate progression from 1920x1080 to 3840x2160 reveals a classic shift in system bottleneck. At 1080p with Low settings, the combination produces an average of 149 FPS, which suggests that the CPU is doing the heavy lifting to keep the frame rate high, as the GPU is not fully saturated at this lower resolution and preset. Moving to 2560x1440 Low, the average drops to 120 FPS, a 19.5% decrease, and at 3840x2160 Low, it falls to 88 FPS, a further 26.7% reduction from the 1440p figure. This scaling pattern indicates that as resolution increases, the GPU becomes the primary limiting factor, with the frame rate dropping proportionally to the increase in pixel workload.

The scaling behavior is even more pronounced when examining the High preset. At 1080p High, the average frame rate is 87 FPS. When the resolution is increased to 2560x1440 High, the average drops to 70 FPS, a 19.5% reduction, and at 3840x2160 High, it falls to 52 FPS, a 25.7% drop from the 1440p result. The consistent percentage drops between resolutions suggest a well-balanced system where the GPU is scaling predictably, but the absolute numbers at 4K indicate that this combination is not optimized for ultra-high-resolution gaming with high detail levels, as the 52 FPS average is below the 60 FPS threshold that many consider the baseline for smooth play.

The largest absolute delta between presets occurs at 1080p, where the difference between Low (149 FPS) and Ultra (83 FPS) is 66 FPS, a 44.3% reduction. This gap narrows at 1440p, with a 53 FPS difference between Low (120 FPS) and Ultra (67 FPS), and narrows further at 4K, with only a 39 FPS difference between Low (88 FPS) and Ultra (49 FPS). This trend confirms that at lower resolutions, the CPU has more headroom to push higher frame rates, but the GPU's workload increases more significantly with resolution, tightening the performance spread across settings at higher pixel counts.

GPU Role

The AMD Radeon RX 7800 XT features 16 GB of GDDR6 memory on a 256-bit bus, providing a memory bandwidth of 624.1 GB/s. This substantial memory capacity is particularly relevant for Microsoft Flight Simulator, which is known for loading large amounts of terrain and scenery data. The benchmark data shows that even at 4K with Ultra settings, the system maintains an average of 49 FPS, indicating that the 16 GB VRAM allocation is sufficient to prevent memory-related stuttering or texture thrashing, as the frame rate remains stable rather than exhibiting severe dips.

The GPU's clock speeds, with a base of 1295 MHz and a boost of 2430 MHz, contribute to its overall compute capability, with a peak FP32 performance of 37.32 TFLOPS. This raw compute power is evident in the measured results, where the GPU is able to drive frame rates from 88 FPS at 4K Low to 149 FPS at 1080p Low. The RDNA 3.0 architecture, built on a 5 nm process with 28,100 million transistors, provides the efficiency needed to sustain these performance levels, though the 263 W TDP suggests that power delivery is not a constraint in these tests.

The GPU's role becomes more pronounced as settings increase. At 1080p, the difference between Low and Medium is 33 FPS (149 to 116), while the difference between Medium and High is 29 FPS (116 to 87). This non-linear scaling suggests that the GPU is still able to handle the increased workload from higher settings at this resolution. However, at 4K, the differences compress: Low to Medium is 19 FPS (88 to 69), and Medium to High is 17 FPS (69 to 52). This compression indicates that the GPU is nearing its saturation point at 4K, where each incremental increase in settings has a smaller impact on frame rate because the GPU is already working near its maximum capacity.

How This Combo Ranks

This specific combination of the AMD Ryzen 5 7400F and AMD Radeon RX 7800 XT ranks 1236 out of 3714 tested combos in Microsoft Flight Simulator. This places the combo in the 66.7th percentile of all tested systems, meaning it outperforms roughly two-thirds of the combinations in the database for this specific title. The ranking reflects a balanced pairing where neither component is severely bottlenecking the other, though the overall position suggests that there are more powerful combinations available for users seeking the absolute highest frame rates.

The CPU's individual performance relative to its rivals shows it is closely matched with several other processors. The Ryzen 5 7400F has an average benchmark score of 32750, which is 0.1% ahead of the Intel Core i5-14600T (32707), 0.2% ahead of the Intel Core Ultra 7 155H (32697), and 0.3% ahead of the AMD Ryzen AI 7 PRO 360 (32662). It sits 0.2% behind the AMD Ryzen 7 PRO 6850H (32812). These negligible differences indicate that the CPU is not a differentiating factor in the combo's ranking, as any of these processors would likely produce similar results in this game.

The GPU's ranking tells a different story. The RX 7800 XT has an average benchmark score of 11627, which is 0.5% behind the NVIDIA GeForce GTX 1660 (11680) and 1.8% behind the AMD Radeon RX 6500 XT (11842). It is 0.9% ahead of the AMD Radeon Pro 5500M (11528) and 1.3% ahead of the NVIDIA Tesla K20c (11479). The fact that the GPU is closely matched with much older or lower-tier cards in synthetic benchmarks, yet the combo still achieves a top-third ranking in this game, suggests that Microsoft Flight Simulator is particularly sensitive to the GPU's specific strengths, such as its 16 GB memory capacity and high bandwidth, which may not be fully reflected in the average benchmark score.

The Medium preset averages 93 FPS, with a minimum of 79 FPS and a maximum of 107 FPS. The High preset averages 70 FPS, and the Ultra preset averages 67 FPS. The difference between High and Ultra at 1440p is only 3 FPS, suggesting that the Ultra preset's additional graphical features have a minimal impact on performance at this resolution, likely because the GPU is already handling a significant workload.

At 3840x2160, the system struggles to maintain high frame rates. The Low preset averages 88 FPS, which is the only 4K setting that remains above 60 FPS. The Medium preset averages 69 FPS, with a minimum of 59 FPS and a maximum of 79 FPS, indicating that users may experience occasional dips below the 60 FPS threshold. The High preset averages 52 FPS, and the Ultra preset averages 49 FPS. These latter two settings are not ideal for a smooth experience, as the frame rates are below 60 FPS and approach the 30 FPS territory that is often considered the minimum for playable performance.

Settings Recommendations

Based on the measured data, the optimal experience for this combination varies by resolution. At 1920x1080, the Ultra preset is recommended, as the 83 FPS average provides a high-quality visual experience without sacrificing smoothness. The gap between High (87 FPS) and Ultra (83 FPS) is only 4 FPS, so users can enable the highest settings without a meaningful performance penalty. For users who prioritize maximum frame rates, the Low preset at 149 FPS offers an exceptionally smooth experience, but the visual quality is significantly reduced.

At 2560x1440, the High preset is the best choice, delivering 70 FPS with good visual fidelity. The Ultra preset at 67 FPS is nearly identical in performance, so users can choose either based on their preference for the specific Ultra features. The Medium preset at 93 FPS is also viable, offering a higher frame rate with a moderate reduction in visual quality. The Low preset at 120 FPS is recommended only for competitive play or if the user prioritizes frame rate above all else, as the visual downgrade is substantial.

At 3840x2160, the Medium preset is the most balanced option, with an average of 69 FPS and a minimum of 59 FPS. This ensures that the experience remains mostly smooth, with only occasional dips below 60 FPS. The Low preset at 88 FPS is the best choice for users who want a consistently high frame rate at 4K, but it sacrifices significant visual detail. The High preset at 52 FPS and Ultra at 49 FPS are not recommended, as the sub-60 FPS frame rates can lead to noticeable stuttering and a less immersive experience in a slow-paced game like Microsoft Flight Simulator.
