# Microsoft Flight Simulator — Intel Core i5-14400F + AMD Radeon RX 6700 XT

This combination of the Intel Core i5-14400F and AMD Radeon RX 6700 XT delivers a playable, though not flawless, Microsoft Flight Simulator experience across common resolutions. The measured frame rates reveal a system that scales predictably with settings and resolution, but the data also exposes where the bottleneck shifts between CPU and GPU depending on the load. The combo ranks 967th out of 1795 tested combinations, placing it in the middle of the pack — a position that suggests balanced, mainstream performance rather than enthusiast-class headroom. The 10-core, 16-thread processor with a 2.50 GHz base and 4.70 GHz boost clock pairs with a 12 GB RDNA 2 GPU that boosts to 2581 MHz, and the measured results show how these two components interact under the demands of a flight simulator that is notoriously sensitive to both processor and graphics throughput.

Resolution Scaling

The frame rate drop from 1080p to 4K is steep but not catastrophic, and the pattern reveals a system that becomes progressively GPU-limited at higher resolutions. At Low settings, the average FPS falls from 123.3 at 1920x1080 to 98 at 2560x1440 — a 20.5% reduction — and then to 72.1 at 3840x2160, another 26.4% drop from the 1440p figure. This consistent decline suggests the RX 6700 XT is the limiting factor as pixel count rises, with the CPU's 10 cores and 16 threads able to feed the GPU adequately even at 4K Low.

The scaling story changes somewhat at higher settings. At Ultra, the 1080p average of 64.5 FPS drops to 55.1 at 1440p (a 14.6% decline) and then to 40.7 at 4K (a 26.1% decline from 1440p). The smaller gap between 1080p and 1440p at Ultra compared to Low hints that the CPU is doing more work at Ultra settings, possibly due to increased physics and AI simulation load, but the GPU still dominates the 4K bottleneck. At Medium, the progression from 93.4 FPS at 1080p to 76.9 at 1440p and 56.8 at 4K shows a nearly linear scaling with pixel count, reinforcing that this combo's performance is largely resolution-bound rather than settings-bound in the mid-range.

What the data implies is that the RX 6700 XT's 384.0 GB/s memory bandwidth and 192-bit bus are sufficient for 1440p gaming but start to strain at 4K, especially when texture and shading demands increase. The 12 GB VRAM is likely not the constraint here, as even the 4K Ultra result of 40.7 FPS suggests the GPU is processing frames rather than stalling on memory allocation.

How This Combo Ranks

With a combo rank of 967 out of 1795 tested combinations, this pairing sits just above the median in the database. This ranking reflects a mid-tier position that aligns with the individual component percentiles: the CPU scores in the 88th percentile against all CPUs, while the GPU sits in the 77th percentile against all GPUs. The combination of a strong processor with a mid-range graphics card produces a system that is capable but not exceptional for Microsoft Flight Simulator.

The CPU's nearest rivals provide context for its contribution. The Intel Core i7-12800H matches the i5-14400F almost exactly with a 0% deltaPct, while the AMD Ryzen 5 PRO 7645 is 0.2% higher and the AMD Ryzen 7 250 is 0.2% lower. These tiny differences suggest that the i5-14400F delivers performance on par with mobile and desktop chips from adjacent generations, meaning its 10 cores and 20 MB of shared L3 cache are competitive for this workload. On the GPU side, the RX 6700 XT's nearest rivals include the AMD Radeon RX 6800 at 0.7% higher average score, and the NVIDIA RTX A5000 at 1.3% higher, while the AMD Radeon HD 7950 and RX 480 are both about 1% lower. The RX 6700 XT's position between these older and newer cards shows it holds its own in raw compute, but the flight simulator's specific demands may not align perfectly with its strengths.

The rank of 967 suggests that many other combos achieve better frame rates, likely due to more powerful GPUs or CPUs with higher single-thread performance, which is critical for this game's simulation logic.

Settings Recommendations

The measured data points to Medium settings as the sweet spot for this combo across all three resolutions, offering the best balance of visual quality and frame rate headroom. At 1080p, Medium produces 93.4 FPS, which is 29.9 FPS higher than High and 28.9 FPS higher than Ultra — a substantial margin that allows for smoother gameplay without sacrificing too much visual fidelity. At 1440p, Medium delivers 76.9 FPS, which remains comfortably above the 60 FPS threshold for most displays, while High drops to 54.1 and Ultra to 55.1, both below that target. At 4K, Medium's 56.8 FPS is close to playable, but the 72.1 FPS at Low is the only setting that provides clear headroom above 60 FPS.

For users prioritizing smoothness over maximum detail, Low at 4K is the only viable option based on the data, as it is the sole 4K setting to exceed 70 FPS. At 1440p, Medium appears ideal, as it surpasses 60 FPS while retaining more visual features than Low. At 1080p, users can afford to push to High or Ultra, though the 64.5 FPS at Ultra is barely above 60 and may dip in dense scenery. The data suggests that Medium is the default recommendation, with High reserved for 1080p users who prefer sharper textures over frame rate stability.

Measured FPS Breakdown

At 1920x1080, the full settings range shows a clear hierarchy: Low leads at 123.3 FPS, followed by Medium at 93.4 FPS, High at 73.3 FPS, and Ultra at 64.5 FPS. The gap between Low and Medium is 29.9 FPS, while the gap between Medium and High is 20.1 FPS, and High to Ultra is 8.8 FPS. This diminishing returns pattern means that each step up in settings costs progressively less performance, with the largest single drop occurring when moving from Low to Medium.

At 2560x1440, the numbers shift downward: Low achieves 98 FPS, Medium 76.9 FPS, High 54.1 FPS, and Ultra 55.1 FPS. Notably, Ultra actually outperforms High by 1 FPS, which is within measurement variance but suggests that the Ultra preset may adjust certain settings that are less demanding on this GPU. The 1440p results show that only Low and Medium exceed 60 FPS, while High and Ultra fall below that threshold.

At 3840x2160, the pattern continues: Low delivers 72.1 FPS, Medium 56.8 FPS, High 40.2 FPS, and Ultra 40.7 FPS. Again, Ultra edges out High slightly, reinforcing the idea that the Ultra preset's specific configuration may be better optimized for this GPU's architecture. The 4K results indicate that Low is the only preset that maintains 60+ FPS, and even it drops by 26.1 FPS compared to the 1440p Low result.

CPU Role

The Intel Core i5-14400F brings 10 cores and 16 threads to the simulation, with a base clock of 2.50 GHz and a boost clock of 4.70 GHz. These specifications place it in the 88th percentile against all CPUs, and its Cinebench R23 multi-core score of 21914 and single-core score of 3093 indicate strong all-around performance. For Microsoft Flight Simulator, the single-thread performance is often critical for the main simulation loop, and the 4.70 GHz boost clock provides the necessary speed for those tasks.

The CPU's 20 MB of shared L3 cache and per-core L2 cache of 1.25 MB help reduce memory latency, which can be beneficial for the game's continuous terrain streaming and weather calculations. The 65 W TDP suggests efficient power draw, but the game's demands may push the processor into boost states frequently. The data shows that at 1080p Low, the CPU is able to feed the GPU enough to reach 123.3 FPS, indicating it is not a significant bottleneck at lower resolutions, but at 1080p Ultra, the 64.5 FPS result could indicate some CPU limitation as the simulation complexity increases.

The nearest rival comparison shows the i5-14400F is essentially tied with the i7-12800H, which is a mobile chip, and slightly ahead of the Ryzen 5 PRO 7645, suggesting that its architecture is well-suited for this workload. The L3 cache size and core count appear adequate for the game's multithreaded rendering and physics.

GPU Role

The AMD Radeon RX 6700 XT is built on the RDNA 2.0 architecture with a 7 nm process and contains 17,200 million transistors on a 335 mm² die. Its 2560 shading units and 40 ray tracing cores provide the raw compute for rendering, while the 12 GB of GDDR6 memory on a 192-bit bus delivers 384.0 GB/s of bandwidth. The boost clock of 2581 MHz is relatively high, and the game clock of 2424 MHz provides a sustained performance level.

The GPU's 77th percentile ranking against all GPUs places it as a mid-range part, and its Passmark G3D score of 19786 reflects solid DirectX performance. The 3DMark Steel Nomad DX12 score of 2435 suggests competent modern API support, which is relevant for a game that uses DirectX 12. The 13.21 TFLOPS of FP32 compute is substantial, but the 4K results show that this is not enough to maintain high frame rates at maximum settings.

The nearest rival data shows the RX 6700 XT is close to the RX 6800 (0.7% lower) and RTX A5000 (1.3% lower), which are both higher-tier cards. The fact that it also sits just above the RX 480 and HD 7950 (both 1% lower) highlights its position as a generational improvement over older GPUs but not a leap ahead. The measured FPS data suggests that the GPU's memory bandwidth and pixel rate of 165.2 GPixel/s are sufficient for 1440p Medium at 76.9 FPS, but the 4K Ultra result of 40.7 FPS indicates that the GPU's compute resources are stretched thin at higher resolutions and settings.
