# Microsoft Flight Simulator — Intel Core i5-10400F + AMD Radeon RX 6650 XT

The combined mid-range pairing of the Intel Core i5-10400F with the AMD Radeon RX 6650 XT lands at rank 2392 out of 3714 tested combos in Microsoft Flight Simulator, placing it in the lower-middle tier of the benchmark database. The data set reveals a system that can deliver playable framerates at 1080p but begins to strain significantly as resolution climbs, with the GPU's 8 GB VRAM and the CPU's six-core Comet Lake architecture each playing distinct roles in shaping the experience. The measured FPS rows show a clear pattern: this combo is tuned for 1080p gaming, where it achieves 58-105 FPS depending on settings, but 4K Ultra drops to 35 FPS, indicating a hard ceiling on visual fidelity at high resolutions.

Resolution Scaling

The resolution scaling behavior in Microsoft Flight Simulator is dramatic and reveals a system that transitions from CPU-bound to GPU-bound as pixel count increases. At 1080p Low, the combo produces 105 FPS, which is the highest measured value across all resolutions. Dropping to 1440p Low yields 84 FPS, a 20% reduction, while 4K Low produces 62 FPS, representing a 41% drop from the 1080p baseline. This scaling pattern suggests that at lower resolutions, the frame rate is heavily influenced by the CPU's ability to feed the GPU with draw calls — a scenario where the i5-10400F's 6 cores and 12 threads at up to 4.30 GHz boost clock are doing the heavy lifting.

The medium settings tier tells a slightly different story, as the GPU begins to assert its influence. At 1080p Medium, the combo achieves 81 FPS, while 1440p Medium drops to 66 FPS, and 4K Medium falls to 48 FPS. The percentage drops between these steps are 18.5% and 27.3% respectively, showing that the RX 6650 XT's 8 GB GDDR6 memory on a 128-bit bus with 280.3 GB/s bandwidth starts to become the limiting factor as resolution increases. The 4K Medium row includes min and max FPS values of 41 and 56, indicating some frame-time variance that could impact smoothness during complex flight scenarios.

At High settings, the pattern continues: 61 FPS at 1080p, 49 FPS at 1440p, and 36 FPS at 4K. The Ultra preset is the most demanding, with 58 FPS at 1080p, 47 FPS at 1440p, and 35 FPS at 4K. The gap between High and Ultra at 1080p is only 3 FPS, but at 1440p it widens to 2 FPS, and at 4K it narrows to just 1 FPS. This compression of performance at the highest settings indicates that the GPU is hitting a hard computational ceiling, likely due to the combination of the 2048 shading units and the 64 ROPs on the Navi 23 chip.

The data implies that the limiting component shifts based on resolution and settings. At 1080p Low, the CPU's single-thread performance — evidenced by a 3dmark single-thread score of 688 — is likely the primary constraint, preventing the GPU from reaching even higher frame rates. At 4K Ultra, the GPU's raw throughput is the bottleneck, as the 10.79 TFLOPS FP32 performance of the RX 6650 XT cannot keep pace with the rendering demands of Microsoft Flight Simulator's detailed terrain and weather systems.

GPU Role

The AMD Radeon RX 6650 XT, built on the RDNA 2.0 architecture with the Navi 23 chip, plays a nuanced role in this combo's performance profile. The GPU's memory configuration — 8 GB of GDDR6 across a 128-bit bus — proves adequate for 1080p and 1440p gaming but becomes a limiting factor at 4K. The memory bandwidth of 280.3 GB/s is a modest figure, and the measured FPS data shows that at 4K, even Low settings yield only 62 FPS, suggesting that the memory subsystem is being saturated by the larger frame buffers required at that resolution.

The clock speeds of the RX 6650 XT are notable: a base clock of 2055 MHz, a game clock of 2410 MHz, and a boost clock of 2635 MHz. These aggressive clocks help explain why the GPU can sustain 105 FPS at 1080p Low, as the high boost frequency compensates for the relatively modest pixel rate of 168.6 GPixel/s. However, the 64 ROPs are a constraint, and the data shows that increasing settings from Low to Ultra at 1080p costs 47 FPS (from 105 to 58), a 45% reduction that reflects the GPU's limited fill-rate capacity when handling more complex shaders and textures.

The GPU's benchmark scores provide context for its role. A passmark G3D score of 17166 places the RX 6650 XT at the 65th percentile among all GPUs, with nearest rivals including the NVIDIA Tesla K40m (avg score 19885, delta -0.6%) and AMD FirePro W7000 (avg score 19905, delta -0.7%). These rivals are professional-grade cards with different design goals, but the delta percentages indicate that the RX 6650 XT is competitive with them in raw compute terms. The 3dmark Steel Nomad DX12 score of 1859 further demonstrates the GPU's capability, though Microsoft Flight Simulator's engine appears to be more sensitive to memory bandwidth than raw compute, given the steep FPS drops at higher resolutions.

The 8 GB VRAM is adequate for the measured settings, but the data shows that at 4K Medium, the frame rate drops to 48 FPS, and at 4K Ultra, it falls to 35 FPS. These figures suggest that the GPU is not only compute-limited but also potentially VRAM-limited, as the flight simulator's high-resolution textures can easily exceed 8 GB when combined with the game's dynamic weather and terrain streaming systems.

How This Combo Ranks

The combo rank of 2392 out of 3714 tested combos places this system in the 64th percentile — meaning roughly 36% of tested combos perform worse in Microsoft Flight Simulator. This ranking is consistent with the hardware's mid-range positioning: the i5-10400F sits at the 68th percentile among all CPUs with an average benchmark score of 14185, while the RX 6650 XT sits at the 65th percentile among GPUs with an average benchmark score of 19765.

The CPU's nearest rivals in the benchmark database include the Intel Xeon 6756E (avg score 14163, delta 0.2%) and the AMD EPYC 7552 (avg score 14115, delta 0.5%). These comparisons show the i5-10400F is solidly in the middle of the pack, with its 6 cores and 12 threads delivering balanced multi-threaded performance. The GPU's nearest rivals are the NVIDIA Tesla K40m (delta -0.6%) and AMD FirePro D300 (delta 0.7%), indicating that the RX 6650 XT is competitive with a range of professional and consumer cards from different generations.

The rank of 2392 suggests that while this combo is not a top-tier performer in Microsoft Flight Simulator, it is far from the bottom. The 3714 total combos represent a wide range of hardware configurations, and this pairing's position in the lower-middle segment is expected given the GPU's 8 GB VRAM and the CPU's 14 nm Comet Lake architecture, which is now several generations old. The data implies that users with this combo should not expect to run the game at maximum settings at high resolutions, but the 1080p performance is competitive with many other tested configurations.

Measured FPS Breakdown

The measured FPS data provides a comprehensive picture of this combo's performance across 12 distinct scenarios. At 1920x1080, the lowest resolution tested, the Low preset achieves 105 FPS, which is a very playable frame rate for a flight simulator. Medium drops to 81 FPS with a min of 69 and max of 94, showing a stable frame delivery with only 25 FPS of variance between minimum and maximum. High settings produce 61 FPS, and Ultra yields 58 FPS — a modest 3 FPS difference that suggests the CPU is starting to limit performance at higher settings, as the GPU has more headroom than the CPU can feed.

Moving to 2560x1440, the Low preset still delivers 84 FPS, which is excellent for a 1440p flight sim experience. Medium drops to 66 FPS with a min of 56 and max of 75, indicating some frame-time spikes during complex scenes. High settings produce 49 FPS, and Ultra yields 47 FPS. The 2 FPS gap between High and Ultra at 1440p is narrower than at 1080p, suggesting the GPU is becoming more of a bottleneck. The 1440p Medium row shows a 19 FPS range between min and max, which could be noticeable as stuttering during terrain loading or weather changes.

At 3840x2160, the performance drops significantly. Low settings achieve 62 FPS, which is playable, but Medium drops to 48 FPS with a min of 41 and max of 56. High settings produce 36 FPS, and Ultra yields 35 FPS. The 4K Ultra figure of 35 FPS is below the 60 FPS threshold that most gamers consider smooth, and even the 4K Medium figure of 48 FPS may be borderline for a game that requires precise control inputs. The 4K Medium min FPS of 41 indicates that in dense areas or during heavy weather effects, the frame rate can dip further.

The data shows a consistent pattern across all settings: the 1080p to 1440p transition costs roughly 20-25% performance, while the 1440p to 4K transition costs another 25-30%. This scaling is typical for a GPU with 8 GB VRAM and a 128-bit memory bus, as the bandwidth requirements increase quadratically with resolution.

Settings Recommendations

Based on the measured FPS rows, the optimal settings for this combo depend on the user's resolution and performance priorities. At 1080p, the High preset at 61 FPS offers the best balance of visual quality and smoothness, as the jump to Ultra only yields 58 FPS — a 3 FPS gain that is unlikely to justify the additional visual fidelity. The Medium preset at 81 FPS is also a strong choice for users who prefer higher frame rates, as the flight simulator benefits from smoother motion during landing approaches and low-altitude maneuvers.

For 1440p users, the data suggests that Medium settings at 66 FPS are the sweet spot, as the High preset drops to 49 FPS, which may be too low for a game that requires precise control. The Low preset at 84 FPS is viable for competitive play or for users with high-refresh-rate monitors, but the visual compromise may be significant for a flight simulator that emphasizes scenery detail. The Ultra preset at 47 FPS is not recommended, as the 2 FPS gain over High does not justify the additional performance cost.

At 4K, the data indicates that only the Low preset at 62 FPS is truly playable, with Medium at 48 FPS being borderline. The High and Ultra presets at 36 and 35 FPS respectively are below the playable threshold for most users. The 4K Medium min FPS of 41 suggests that even this preset can drop below 45 FPS in demanding scenes, making it a risky choice for a game where smooth frame delivery is important for immersion.

The overall recommendation from the data is to use Medium settings at 1080p or 1440p, as these provide the best combination of visual quality and frame rate stability. Users with 4K displays should either lower their resolution to 1440p or accept Low settings, as the GPU's 8 GB VRAM and 64 ROPs are insufficient for high-quality 4K rendering in this game.

CPU Role

The Intel Core i5-10400F, with its 6 cores and 12 threads, plays a critical role in this combo's performance, particularly at lower resolutions and settings. The CPU's base clock of 2.90 GHz and boost clock of 4.30 GHz provide enough single-thread performance for Microsoft Flight Simulator's main thread, which handles the game's core simulation logic. The 3dmark single-thread score of 688 and the passmark single-thread score of 2541 indicate that this CPU is capable for gaming, but its 14 nm Comet Lake architecture is showing its age compared to more modern designs.

The CPU's multi-threaded performance, as evidenced by the cinebench R23 multicore score of 10283 and the passmark multithread score of 12115, suggests that the 12 threads are sufficient for the game's background tasks, such as terrain streaming and AI traffic simulation. However, the data shows that at 1080p Low, the frame rate is capped at 105 FPS, which may be a CPU limitation — the GPU is capable of higher frame rates, as evidenced by its passmark G3D score of 17166, but the CPU cannot feed it fast enough.

The CPU's nearest rivals in the benchmark database include the Intel Core 7 160UL (avg score 14232, delta -0.3%) and the AMD Ryzen 3 7320C (avg score 14277, delta -0.6%). These comparisons show that the i5-10400F is competitive with newer low-power chips, but it lags behind modern mid-range CPUs in single-thread performance, which is crucial for flight simulators that rely heavily on a single main thread. The 12 MB of shared L3 cache provides adequate data locality for the game's working set, but the 42.7 GB/s memory bandwidth of the dual-channel DDR4 controller may be a limiting factor when the game needs to stream large terrain textures.

The CPU's 65 W TDP and 14 nm process node also have implications for system thermals and power consumption, though these are not directly measured in the FPS data. The data implies that for users who want to improve performance in Microsoft Flight Simulator, upgrading the CPU could yield significant gains at 1080p, where the GPU has more headroom. At 4K, however, the GPU is the primary bottleneck, and a CPU upgrade would have minimal impact on frame rates.
