# Microsoft Flight Simulator: Intel Core i5-14600KF + AMD Radeon RX 6750 XT

This combination of the Intel Core i5-14600KF and AMD Radeon RX 6750 XT ranks 1674 out of 3714 tested combos in Microsoft Flight Simulator, placing it in the 55th percentile of all pairings evaluated. The CPU itself sits at the 90th percentile against all processors in general benchmark data, while the GPU reaches the 71st percentile among all graphics cards — a notable gap that hints at where the performance ceiling lives in this flight sim. The measured FPS data reveals a system that can handle the game comfortably at 1080p and 1440p, but struggles to maintain smooth framerates at 4K on higher presets, suggesting the graphics card becomes the primary constraint as resolution climbs.

How This Combo Ranks

The combo's rank of 1674 out of 3714 places it slightly above the median of all tested pairings, which is a respectable position given the mid-range nature of both components. The Intel Core i5-14600KF demonstrates strong synthetic performance with an average benchmark score of 49394, landing just 0.3% behind the AMD Ryzen 9 7900 and 0.8% ahead of the Intel Core Ultra 5 245. This CPU is clearly not the bottleneck in most scenarios, as its single-core and multi-core scores in Cinebench R23 (4594 and 32544 respectively) indicate robust processing power that flight simulators typically leverage heavily for physics, weather, and AI traffic calculations.

The AMD Radeon RX 6750 XT, by contrast, shows a more modest standing with an average benchmark score of 26011, placing it just 0.5% ahead of the AMD Radeon R9 M395X and 1.1% ahead of the NVIDIA GeForce RTX 3080 Ti Mobile. The GPU's 71st percentile ranking versus the CPU's 90th percentile highlights a meaningful imbalance — the processor has more headroom than the graphics card can exploit, particularly at higher resolutions. The measured FPS data confirms this interpretation: at 1080p Low the system delivers 127 FPS, but that number drops by nearly half at 4K Ultra to 42 FPS, a pattern consistent with GPU-bound performance.

When examining where this combo falls in the broader context, the rank of 1674 out of 3714 means roughly 55% of tested combinations perform better, but many of those likely pair higher-tier GPUs with similar or weaker CPUs. The data suggests this pairing is well-balanced for 1080p and 1440p gaming but leaves performance on the table at 4K, where the GPU's 12 GB of VRAM and 432.0 GB/s bandwidth struggle to keep pace with the CPU's capabilities.

GPU Role

The AMD Radeon RX 6750 XT is built on the RDNA 2.0 architecture with a 7 nm process node, featuring 2560 shading units, 160 TMUs, and 64 ROPs. Its base clock runs at 2150 MHz, boosting up to 2600 MHz, with a game clock of 2495 MHz that represents typical sustained performance during gaming workloads. The memory subsystem consists of 12 GB of GDDR6 on a 192-bit bus, delivering 432.0 GB/s of bandwidth — a configuration that proves adequate for 1080p and 1440p but becomes strained at 4K with higher detail settings.

In Microsoft Flight Simulator specifically, the GPU's role is critical due to the game's heavy reliance on texture streaming and detailed terrain rendering. The measured FPS data shows the GPU's impact clearly: at 1080p Medium the combo achieves 99 FPS (84 min, 113 max), but at 4K Medium it drops to 59 FPS (50 min, 67 max). This 40% reduction in average framerate from 1080p to 4K at the same settings indicates the GPU is the limiting factor, as the CPU has ample headroom with its 14 cores and 20 threads.

The RX 6750 XT's DirectX 12 Ultimate support and 40 RT cores provide modern API compatibility, though Microsoft Flight Simulator does not heavily utilize ray tracing. The GPU's 13.31 TFLOPS of FP32 compute and 416.0 GTexel/s texture rate are sufficient for the game's complex scenery rendering, but the 4K Ultra result of 42 FPS suggests the card is pushed to its limits at maximum settings. The 12 GB VRAM capacity is worth noting — flight simulators can consume significant memory with high-resolution textures, and 12 GB provides some headroom, but the 192-bit bus width limits memory bandwidth compared to wider implementations.

Resolution Scaling

The FPS scaling across resolutions reveals a predictable pattern with the GPU as the primary constraint. From 1080p to 1440p, average framerates drop by roughly 20-25% across all settings: High falls from 74 to 60 FPS, Medium from 99 to 79, Low from 127 to 102, and Ultra from 71 to 57. This scaling is consistent with GPU-bound behavior, as the additional pixel count increases the rendering workload proportionally.

The jump from 1440p to 4K produces a more dramatic decline, with High dropping from 60 to 44 FPS (27% reduction), Medium from 79 to 59 (25% reduction), and Ultra from 57 to 42 (26% reduction). Interestingly, Low settings show the smallest relative drop from 102 to 75 FPS (26% reduction), suggesting that even at the lowest preset, the GPU remains the limiting factor. The fact that no settings combination produces a sub-40 FPS average at 4K indicates the combo can technically run the game at 4K, but only at Low or Medium settings for acceptable playability.

The data implies that the CPU's 5.30 GHz boost clock and 24 MB of shared L3 cache are sufficient to feed the GPU at 1080p, where framerates reach 127 FPS at Low settings. However, the GPU's bandwidth and compute limitations become apparent at higher resolutions, where the framerate drops are consistent with pixel-throughput constraints rather than CPU bottlenecks. This pattern suggests that users targeting 4K would benefit from a more powerful GPU, while the CPU remains a capable partner for 1080p and 1440p gaming.

Measured FPS Breakdown

At 1920x1080, the combo delivers its strongest performance. Low settings produce an average of 127 FPS, Medium achieves 99 FPS (84 min, 113 max), High hits 74 FPS, and Ultra reaches 71 FPS. The gap between Low and Medium is 28 FPS, while the difference between High and Ultra is only 3 FPS — indicating diminishing returns at the top end of the settings range. The 84 FPS minimum at Medium suggests occasional dips, but the overall experience remains smooth for most displays.

Moving to 2560x1440, all settings see notable reductions. Low averages 102 FPS, Medium 79 FPS (68 min, 91 max), High 60 FPS, and Ultra 57 FPS. The Medium preset shows a 79 FPS average with a 68 FPS minimum, which remains playable but approaches the threshold where motion smoothness may suffer on high-refresh monitors. The High and Ultra results of 60 and 57 FPS respectively are right at the edge of 60 Hz displays, making them viable but not ideal for competitive or fast-paced scenarios.

At 3840x2160, performance becomes marginal. Low averages 75 FPS, Medium 59 FPS (50 min, 67 max), High 44 FPS, and Ultra 42 FPS. The 50 FPS minimum at Medium is concerning for smooth gameplay, as it indicates potential stuttering during complex scenes. High and Ultra presets at 4K produce framerates below 45 FPS, which may be acceptable for a flight simulator's slower pace but falls short of the smoothness most gamers expect. The data clearly shows that 1080p and 1440p are the sweet spots for this combination, with 4K reserved for Low or Medium settings.

Settings Recommendations

Based on the measured FPS data, the optimal experience depends on the target resolution. At 1920x1080, Ultra settings at 71 FPS average provide the best visual quality without sacrificing smoothness, making this the recommended preset for 1080p displays. The 3 FPS difference between High (74 FPS) and Ultra (71 FPS) is negligible, so choosing Ultra maximizes visual fidelity.

For 2560x1440, Medium settings at 79 FPS (68 min, 91 max) offer the best balance, as High drops to 60 FPS and Ultra to 57 FPS — both right at the edge of 60 Hz refresh rates. The 68 FPS minimum at Medium ensures fewer noticeable dips during complex scenes, making this the safest choice for consistent performance.

At 3840x2160, Low settings at 75 FPS are the only option that maintains a comfortable margin above 60 FPS. Medium at 59 FPS (50 min, 67 max) is playable but risks dips below 60 FPS, while High and Ultra at 44 and 42 FPS respectively fall short of smooth gameplay. For 4K users, Low settings provide the most reliable experience, with Medium as a compromise if minor stuttering is acceptable.

The data suggests that the combo's sweet spot is 1440p Medium or 1080p Ultra, where the GPU's capabilities align well with the CPU's performance. Users with high-refresh 1080p monitors can enjoy Ultra settings, while those with 1440p displays should prioritize Medium for framerate stability.

CPU Role

The Intel Core i5-14600KF features 14 cores and 20 threads, combining performance and efficiency cores in a Raptor Lake architecture built on Intel's 10 nm process. Its base clock of 3.50 GHz boosts up to 5.30 GHz, with a 125 W TDP that indicates substantial power delivery requirements. The 24 MB shared L3 cache and dual-channel memory support for DDR4 and DDR5 provide the memory bandwidth necessary for flight simulation workloads.

In Microsoft Flight Simulator, the CPU handles physics calculations, weather simulation, AI traffic, and scenery loading — tasks that benefit from high single-thread performance. The Cinebench R23 single-core score of 4594 places it among the top processors, while the multi-core score of 32544 ensures smooth handling of background tasks. The 90th percentile ranking against all CPUs confirms that this processor can handle the game's demanding computational requirements without becoming a bottleneck.

The measured FPS data supports this assessment: at 1080p Low, the combo reaches 127 FPS, indicating the CPU can feed the GPU adequately even at high framerates. The fact that framerates drop consistently across resolutions and settings, rather than showing a plateau at a CPU-limited ceiling, suggests the processor maintains sufficient headroom. The nearest rival comparisons — 0.3% ahead of the AMD Ryzen 9 7900 and 0.8% ahead of the Intel Core Ultra 5 245 — show the i5-14600KF holds its own against higher-tier options.

The CPU's 20 threads and boost clock of 5.30 GHz are particularly relevant for flight simulators, which often exhibit single-thread sensitivity. The PassMark single-thread score of 4273 and Geekbench single-core score of 2445 reinforce this strength ape. However, the CPU's performance advantage becomes less relevant at 4K, where the GPU's limitations dominate. This suggests that users considering an upgrade path might prioritize a stronger GPU to complement the CPU's capabilities, rather than investing in a higher-end processor.
