Microsoft Flight Simulator

The Intel Core i5-10400F paired with the AMD Radeon RX 7900 XT delivers a versatile experience in Microsoft Flight Simulator, but the data reveals that the Ultra preset is the only setting that fails to provide a consistently smooth experience across all resolutions. The sweet spot for this combination is the High preset at 1440p , which balances visual fidelity with a robust 81.9 FPS average, or the Medium preset at 1080p for those prioritizing higher frame rates at 122.1 FPS. The Ultra preset, while playable at 1080p with 102 FPS, drops below the 60 FPS threshold at 4K (55.9 FPS), making it less ideal for demanding 4K displays.

Settings Recommendations

Benchmark results indicate that the High preset offers the most balanced experience, delivering frame rates above 100 FPS at 1080p (106.2 FPS) and maintaining a solid 81.9 FPS at 1440p. At 4K, the High preset drops to 58.9 FPS, which is borderline for smooth gameplay but still acceptable for a flight simulator where precise timing is less critical than in fast-paced genres. The Medium preset provides a notable performance boost over High, with a 15% increase at 1080p (122.1 vs 106.2 FPS) and a 31% increase at 4K (81.7 vs 58.9 FPS), making it the best choice for 4K displays where the High preset struggles. While the Low preset yields the highest frame rates—136 FPS at 1080p, 124.5 FPS at 1440p, and 105.5 FPS at 4K—the visual compromise is substantial for a game that relies heavily on scenery detail. Ultimately, Medium at 4K or High at 1440p provides the best experience per the measured rows, balancing image quality with performance headroom.

GPU Role

The AMD Radeon RX 7900 XT serves as the primary driver of frame rates in this configuration, especially at higher resolutions. With 20 GB of GDDR6 memory and a 320-bit bus delivering 800.0 GB/s of bandwidth, the GPU has ample resources for Microsoft Flight Simulator's vast textures and detailed environments. The GPU's boost clock of 2394 MHz and game clock of 2025 MHz, built on the 5 nm RDNA 3.0 architecture with 5376 shading units, provide substantial computational power. The data shows a clear GPU-bound behavior: at 1080p, the FPS difference between Low and Ultra settings is 34 FPS (136 vs 102), but at 4K, this gap narrows to 49.6 FPS (105.5 vs 55.9), indicating that the GPU's workload scales significantly with resolution. The card's 51.48 TFLOPS FP32 performance and 804.4 GTexel/s texture rate are well-suited for the game's complex rendering demands, though the Ultra preset pushes the GPU to its limits at 4K where it averages just 55.9 FPS.

Resolution Scaling

The measured FPS data reveals a predictable performance degradation as resolution increases, but the severity depends heavily on the preset. At Low settings, the drop from 1080p to 4K is 30.5 FPS (136 to 105.5), a 22% reduction, while at Ultra settings, the drop is 46.1 FPS (102 to 55.9), a 45% reduction. This disparity highlights that the GPU becomes increasingly the limiting component at higher settings, as the more demanding Ultra preset amplifies the resolution penalty. The scaling from 1440p to 4K at High settings shows a 23 FPS decrease (81.9 to 58.9), while the jump from 1080p to 1440p at the same preset costs 24.3 FPS (106.2 to 81.9). These numbers suggest that the RX 7900 XT maintains playable frame rates up to 1440p on High settings, but 4K requires dropping to Medium or Low to achieve frame rates above 80 FPS. The 6-core, 12-thread i5-10400F with a 2.90 GHz base and 4.30 GHz boost clock appears sufficient to feed the GPU at 1080p, but the GPU's performance ceiling becomes the bottleneck at higher resolutions.

FAQ

Q: What is the best preset for 4K gaming with this combo?

A: The Medium preset at 3840x2160 delivers 81.7 FPS, which is the highest frame rate above 80 FPS at 4K. The High preset drops to 58.9 FPS, and Ultra falls to 55.9 FPS, making Medium the recommended choice for 4K.

Q: How does the Ultra preset perform at 1080p?

A: At 1920x1080 with Ultra settings, the combo achieves 102 FPS average, which is playable but 34 FPS lower than the Low preset at the same resolution (136 FPS). The Ultra preset at 1080p is viable for high-refresh displays, but Medium (122.1 FPS) offers a better balance.

Q: Is the CPU a bottleneck at 1080p?

A: The data suggests the GPU is the primary limiter even at 1080p, as the FPS varies significantly with settings (102 to 136 FPS). The i5-10400F's 6 cores and 12 threads, with a boost clock of 4.30 GHz, provide sufficient processing power to keep frame rates high across all presets.

Q: What is the frame rate difference between High and Ultra at 1440p?

A: At 2560x1440, the High preset averages 81.9 FPS, while Ultra averages 78.7 FPS—a difference of just 3.2 FPS. This small gap indicates diminishing returns from Ultra settings at this resolution.

Q: Can this combo handle 4K at all?

A: Yes, but only with reduced settings. At 4K, the Low preset achieves 105.5 FPS and Medium 81.7 FPS, both above the 60 FPS threshold. High and Ultra fall below 60 FPS, making them less suitable for 4K.

Q: How does the combo rank among all tested configurations?

A: This combination ranks 410th out of 1795 tested combos in Microsoft Flight Simulator, placing it in the top 23% of all configurations tested.

CPU Role

The Intel Core i5-10400F, a 6-core, 12-thread processor from the Comet Lake architecture, plays a supporting role in this configuration. With a base clock of 2.90 GHz and boost clock of 4.30 GHz, the CPU provides adequate single-threaded performance, evidenced by a Geekbench single-core score of 1454 and a Cinebench R23 single-core score of 1453. Multi-threaded performance is also respectable, with a Cinebench R23 multi-core score of 10297 and a Passmark multithread score of 12115. In Microsoft Flight Simulator, which is known for heavy single-threaded workloads, the CPU's single-core capabilities are crucial. The data shows that at 1080p with Low settings, the combo achieves 136 FPS, which is only 21% higher than the 1080p Ultra score of 102 FPS, suggesting the CPU is not a bottleneck even at lower settings where the GPU load is reduced. The CPU's 12 MB of shared L3 cache and support for DDR4 memory at 42.7 GB/s bandwidth are adequate for feeding the GPU, though the GPU's 800.0 GB/s bandwidth far exceeds the CPU's memory throughput, reinforcing that the GPU handles the bulk of the rendering workload.

Measured FPS Breakdown

At 1920x1080, the combo delivers 136 FPS on Low, 122.1 FPS on Medium, 106.2 FPS on High, and 102 FPS on Ultra. The spread of 34 FPS between Low and Ultra indicates that settings have a moderate impact at this resolution. Moving to 2560x1440, the frame rates decrease to 124.5 FPS on Low, 107.5 FPS on Medium, 81.9 FPS on High, and 78.7 FPS on Ultra. The gap between Low and Ultra widens to 45.8 FPS, showing the GPU's workload increasing. At 3840x2160, the scores are 105.5 FPS on Low, 81.7 FPS on Medium, 58.9 FPS on High, and 55.9 FPS on Ultra. The Low-to-Ultra gap at 4K is 49.6 FPS, the largest of all resolutions, confirming that the GPU is heavily taxed at 4K with higher settings. Notably, the Medium preset at 4K (81.7 FPS) outperforms the High preset at 1440p (81.9 FPS) by a negligible margin, showing that resolution scaling is not uniform across settings.

How This Combo Ranks

In the comprehensive database of tested configurations for Microsoft Flight Simulator, this Intel Core i5-10400F and AMD Radeon RX 7900 XT combo ranks 410th out of 1795 combinations, placing it in the top 22.8% of all tested systems. This ranking reflects the GPU's high performance percentile of 82 among all GPUs, while the CPU sits at the 73rd percentile among all CPUs. The GPU's average benchmark score of 38358 is closely matched by its nearest rivals, with the NVIDIA GeForce RTX 5080 Mobile at 38349 (0% delta) and the NVIDIA GeForce RTX 4080 Mobile at 38135 (0.6% delta). The CPU's average score of 14168 is nearly identical to the AMD EPYC 7552 at 14115 (0.4% delta) and the AMD Ryzen 3 7320C at 14277 (-0.8% delta). This ranking suggests that the combination is well-balanced, with the GPU driving the overall performance tier, but the CPU's mid-range standing prevents the combo from reaching the top tier. The data indicates that users seeking higher rankings would need a more powerful CPU to complement the GPU's capabilities, though the current pairing still delivers strong frame rates across most settings and resolutions.
