Microsoft Flight Simulator

Resolution Scaling

The measured data for Microsoft Flight Simulator with the Intel Core i5-14600KF and AMD Radeon RX 7900 XTX shows a clear and predictable pattern of performance degradation as resolution increases. At 1080p, the combo delivers 188.9 FPS on Low settings, which falls to 150.3 FPS at 1440p and 114.1 FPS at 4K. That represents a 20.5% drop from 1080p to 1440p and another 24.1% drop from 1440p to 4K.

The High preset tells a similar story. At 1080p, the system produces 115 FPS; at 1440p, it drops to 87.2 FPS; and at 4K, it reaches 64.8 FPS. The percentage drops are 24.2% and 25.7% respectively. Medium settings show 152 FPS at 1080p, 120.1 FPS at 1440p, and 86 FPS at 4K. Ultra settings yield 105.2 FPS at 1080p, 83.3 FPS at 1440p, and 65 FPS at 4K.

The pattern is consistent across all presets: the largest single-step decline occurs when moving from 1440p to 4K. This indicates that at 4K, the GPU becomes the primary limiting factor. The RX 7900 XTX has 24 GB of GDDR6 memory on a 384-bit bus with 960.0 GB/s bandwidth, which is substantial, yet the raw pixel throughput demands at 3840x2160 push the renderer hard. The frame rate differences between 1080p and 1440p are smaller in absolute terms, suggesting the CPU still has headroom to feed the GPU at those resolutions.

Notably, the gap between Low and Ultra settings narrows as resolution climbs. At 1080p, the difference between Low and Ultra is 83.7 FPS. At 4K, that gap shrinks to 49.1 FPS. This compression is typical of GPU-bound scenarios; when the GPU is saturated, setting changes have less relative impact because the bottleneck shifts away from the render pipeline's configuration toward raw fill rate and shader throughput.

How This Combo Ranks

The combination of Intel Core i5-14600KF and AMD Radeon RX 7900 XTX ranks 227th out of 1795 tested combos in Microsoft Flight Simulator. That places it in the top 12.7% of all configurations in the database for this title. The rank reflects the measured average FPS across all tested presets and resolutions, giving a composite view of the combo's capability.

The CPU's nearest rivals provide context for its contribution. The Intel Core i5-14600K scores 0.4% higher in average benchmark score, which is essentially a tie given measurement variance. The AMD EPYC 4345P is 0.5% higher, and the AMD Ryzen 9 5950X is 0.6% higher. The Intel Xeon Gold 5318H trails by 1.4%. These deltas are all within a narrow band, meaning the 14600KF's processing power is competitive with a wide range of high-end desktop and workstation parts.

On the GPU side, the RX 7900 XTX sits at the 85th percentile among all GPUs. Its nearest rivals include the AMD Radeon Pro 580, which scores 0.4% lower, and the NVIDIA GeForce RTX 4090 Mobile, which scores 0.8% lower. The NVIDIA Quadro M6000 is 1.6% behind, while the NVIDIA GeForce RTX 4070 Ti is 2% ahead. The fact that a mobile RTX 4090 is within 1% of this desktop flagship card underscores how strong the 7900 XTX's position is for this simulation title.

Given that the combo ranks 227th of 1795, the data indicates it outperforms the vast majority of tested systems in Microsoft Flight Simulator. The combination of a top-tier GPU and a high-performing 14-core CPU places it well above the median, and the narrow delta percentages among CPU rivals suggest that component choice among similar-tier parts will not dramatically alter the ranking.

Settings Recommendations

The measured rows provide a clear picture of how each preset behaves at each resolution. For users targeting 4K, the Ultra preset delivers 65 FPS, which is playable but not ideal for a flight simulator where smooth panning over terrain matters. High at 4K yields 64.8 FPS, nearly identical to Ultra. Medium at 4K produces 86 FPS, a substantial 32.6% improvement over Ultra. Low at 4K reaches 114.1 FPS.

At 1440p, the situation is more forgiving. Ultra runs at 83.3 FPS, High at 87.2 FPS, Medium at 120.1 FPS, and Low at 150.3 FPS. For a visually demanding sim like this, High at 1440p offers a balanced experience: 87.2 FPS with most graphical features enabled. Medium at 1440p is the safer choice for maintaining high frame rates during complex scenery loads, as it stays above 120 FPS.

At 1080p, all presets are playable. Low hits 188.9 FPS, Medium 152 FPS, High 115 FPS, and Ultra 105.2 FPS. The difference between High and Ultra is only 9.8 FPS, making Ultra the better choice for 1080p users who want maximum visual quality without sacrificing much performance.

The data suggests that for 4K, Medium is the optimal preset: 86 FPS is smooth, and the visual compromise from Ultra to Medium is less noticeable in a flight sim where ground detail is often viewed from altitude. For 1440p, High provides the best balance of fidelity and fluidity. For 1080p, Ultra is recommended because the frame rate remains above 100 FPS, and the visual gains are worthwhile.

GPU Role

The AMD Radeon RX 7900 XTX is the dominant component in this combo for Microsoft Flight Simulator, particularly at higher resolutions. Its 24 GB of GDDR6 memory on a 384-bit bus provides 960.0 GB/s of bandwidth, which is critical for streaming terrain textures and photogrammetry data that the sim loads dynamically. The GPU's 96 ray accelerators and 192 ROPs handle the rendering workload, and its 6144 shading units process the pixel and compute shaders.

The clock behavior is notable. The base clock is 1929 MHz, the game clock is 2365 MHz, and the boost clock reaches 2498 MHz. In a flight sim, sustained loads tend to keep the GPU near its game clock rather than peak boost, which explains why the 4K Ultra result of 65 FPS is close to the 4K High result of 64.8 FPS — the GPU is already near its practical limit. The memory clock runs at 2500 MHz with 20 Gbps effective, and this bandwidth headroom is used heavily when the sim streams in new scenery tiles.

The GPU's 61.39 TFLOPS of FP32 compute and 122.8 TFLOPS of FP16 are more than sufficient for this title's shader complexity. The fact that the GPU sits at the 85th percentile among all GPUs, with a PassMark G3D score of 31238, indicates it is a high-end part. However, the nearest rival data shows the RTX 4070 Ti is 2% ahead in average benchmark score, which suggests that raw compute is not the only factor; driver optimization and memory subsystem efficiency matter in this sim.

CPU Role

The Intel Core i5-14600KF provides the processing backbone for the simulation's heavy single-threaded and multi-threaded workloads. With 14 cores and 20 threads, it offers a mix of performance and efficiency cores. The base clock is 3.50 GHz, and the boost clock reaches 5.30 GHz. This high boost clock is crucial for flight simulators, which often have a single main thread that handles the flight model and autopilot logic.

The CPU's L3 cache is 24 MB shared, and each core has 2 MB of L2 cache. This cache hierarchy helps reduce memory latency when the sim accesses large world-data structures. In Cinebench R23, the CPU scores 32889 multicore and 4643 single-core. The single-core score is particularly relevant here, as Microsoft Flight Simulator's main thread benefits directly from high single-thread performance. The Geekbench single-core score of 2778 reinforces this strength.

The CPU's nearest rivals are all within 1.4% in average benchmark score, indicating that the 14600KF is well-positioned among similar-tier parts. The 0.4% difference from the 14600K is within run-to-run variance, and the 0.6% gap to the Ryzen 9 5950X is similarly minor. The data suggests that at 1080p, where the CPU has more influence on frame rates, the 14600KF's boost clock of 5.30 GHz helps push the Low preset to 188.9 FPS. At 4K, the CPU's role diminishes relative to the GPU, but the 14-core configuration ensures there is no CPU-induced stutter during complex scenery loads.
