Microsoft Flight Simulator

The data for Microsoft Flight Simulator with the Intel Core i5-14600K and AMD Radeon RX 7900 XT shows a system that scales predictably with resolution, but the relationship between settings and frame rate reveals where the bottleneck shifts. At 4K, the average frame rate drops from 103.7 FPS on Low settings to 54.9 FPS on Ultra, a steep decline of nearly half. This pattern indicates that at 4K Ultra, the GPU is working at its limit, as the gap between Low and Medium is 26.0 FPS, while the gap between High and Ultra is only 4.6 FPS. The 4K High result of 59.5 FPS sits just above the 54.9 FPS Ultra figure, suggesting that the final settings tier demands more from the rendering pipeline than the hardware can comfortably deliver at this resolution.

Stepping down to 1440p, the same settings ladder shows a different story. Low settings produce 143.6 FPS, Medium reaches 112.2 FPS, High drops to 84.7 FPS, and Ultra lands at 79.0 FPS. The delta between High and Ultra here is 5.7 FPS, which is small but not negligible. The 1080p results reinforce this: Low hits 178.8 FPS, Medium 138.3 FPS, High 104.8 FPS, and Ultra 98.2 FPS. The drop from 1080p Ultra to 4K Ultra is 43.3 FPS, a substantial reduction that points to pixel count as the primary limiter. At 1080p, the CPU can feed the GPU enough data to maintain high frame rates, but as resolution climbs, the GPU’s rendering workload becomes the dominant factor. The data shows that this combination is capable of smooth flight simulation at 4K, but only if settings are moderated.

GPU Role

The AMD Radeon RX 7900 XT is built on the RDNA 3.0 architecture with a Navi 31 chip, and its specifications explain much of the 4K behavior. The GPU has 20 GB of GDDR6 memory on a 320-bit bus, delivering 800.0 GB/s of bandwidth, which is ample for the large texture sets and detailed scenery in Microsoft Flight Simulator. The boost clock of 2394 MHz and game clock of 2025 MHz provide the computational headroom needed for the simulator’s continuous geometry and lighting calculations. The GPU’s 5376 shading units and 192 ROPs are directly relevant to the fill-rate demands at higher resolutions, and the 51.48 TFLOPS FP32 performance indicates a card that can handle heavy shader work.

Comparing the GPU to its nearest rivals in the benchmark database, the RX 7900 XT’s average score of 38358 places it nearly identical to the NVIDIA GeForce RTX 5080 Mobile, which scores 38349 with a deltaPct of 0.0. The NVIDIA CMP 70HX scores 38225, a deltaPct of 0.3 percent behind, while the NVIDIA GeForce MX570 scores 38494, a deltaPct of -0.4 percent ahead, and the NVIDIA GeForce RTX 4080 Mobile scores 38135, a deltaPct of 0.6 percent behind. These figures place the RX 7900 XT in the 82nd percentile of all GPUs, meaning it outperforms the majority of tested cards. In the context of this game, the GPU’s 20 GB VRAM is a key asset, as flight simulators often load large photogrammetry areas, and the measured 4K Ultra result of 54.9 FPS shows that the card is not running out of memory but rather reaching its compute limit.

CPU Role

The Intel Core i5-14600K is a 14-core, 20-thread processor with a base clock of 3.50 GHz and a boost clock of 5.30 GHz, built on the Raptor Lake architecture with a 10 nm process. Its 24 MB of shared L3 cache and 2 MB per-core L2 cache help with the simulator’s single-threaded physics and scenery streaming. The CPU’s benchmark scores are strong: a Cinebench R23 multi-core score of 32881 and a single-core score of 4642, along with a Geekbench single-core score of 2803. These numbers place the CPU in the 93rd percentile of all processors, and the average benchmark score of 49166 is close to the AMD Ryzen 9 5950X, which scores 49062 with a deltaPct of 0.2 percent behind.

The CPU’s role in this game is most evident at 1080p, where the frame rates exceed 170 FPS on Low settings. At 178.8 FPS, the CPU is providing enough instructions to keep the GPU busy, but the fact that 1080p Ultra only reaches 98.2 FPS suggests that the GPU is still the limiting factor at higher settings. The 1440p results show a similar pattern, with the gap between Low and Ultra being 64.6 FPS, which is larger than the 1080p gap of 80.6 FPS, indicating that resolution scaling is consistent. The CPU’s nearest rivals in the database include the Intel Core i5-14600KF, which scores 49367 with a deltaPct of -0.4 percent, and the AMD EPYC 4345P, which scores 49595 with a deltaPct of -0.9 percent. The i5-14600K’s boost clock of 5.30 GHz is particularly relevant for flight simulators, which often rely on high single-core performance for frame pacing.

How This Combo Ranks

The combined system of the i5-14600K and RX 7900 XT ranks 359th out of 1795 tested combos in Microsoft Flight Simulator, placing it in the top 20 percent of all configurations. This rank reflects the balance between the CPU’s 93rd percentile standing and the GPU’s 82nd percentile standing. The data shows that this combo is not at the absolute top tier, but it sits comfortably above the median, and the measured frame rates confirm that it can handle the game at high settings across all resolutions. The rank of 359 out of 1795 means that 1436 other combos perform worse, which is a strong indicator of overall capability.

The deltaPct values from the nearest rivals provide context: the CPU is 0.2 percent behind the AMD Ryzen 9 5950X in average score, and the GPU is 0.0 percent different from the NVIDIA GeForce RTX 5080 Mobile. These small deltas suggest that the combo’s performance is tightly clustered with other high-end parts, and the rank is more a function of the game’s specific demands than any single component weakness. The fact that the GPU is end-of-life in production status does not diminish its measured performance in this title, as the 4K High result of 59.5 FPS is close to the 60 FPS target that many users consider optimal for simulation.

Settings Recommendations

Based on the measured FPS rows, the best experience depends on the display resolution. At 3840x2160, the High preset at 59.5 FPS is the sweet spot, as it stays above 55 FPS while delivering more visual detail than Medium at 77.7 FPS. The Ultra preset at 54.9 FPS is borderline, and the 4.6 FPS gain from High to Ultra is not worth the stability risk. At 2560x1440, the Medium preset at 112.2 FPS is the recommended choice for a balance of smoothness and quality, but High at 84.7 FPS is also viable for users who prioritize visuals over frame rate. The 1440p Low preset at 143.6 FPS is unnecessary for most players, as the simulator’s ground and cloud detail suffers. At 1920x1080, the High preset at 104.8 FPS is the clear winner, as it provides a fluid experience with good detail, while Medium at 138.3 FPS is an alternative for competitive or fast-paced flying. The 1080p Ultra at 98.2 FPS is playable but does not offer a meaningful improvement over High.

The data indicates that the Low preset is only useful for benchmarking or extreme frame rate targets, as it produces 178.8 FPS at 1080p and 103.7 FPS at 4K, but the visual penalty is severe. For most users, the High preset across all resolutions is the most consistent choice, with frame rates that range from 59.5 FPS at 4K to 104.8 FPS at 1080p.

Measured FPS Breakdown

The exact measured averages are as follows. At 3840x2160, the Low preset averages 103.7 FPS, Medium averages 77.7 FPS, High averages 59.5 FPS, and Ultra averages 54.9 FPS. At 2560x1440, Low averages 143.6 FPS, Medium averages 112.2 FPS, High averages 84.7 FPS, and Ultra averages 79.0 FPS. At 1920x1080, Low averages 178.8 FPS, Medium averages 138.3 FPS, High averages 104.8 FPS, and Ultra averages 98.2 FPS. These numbers show a consistent pattern: the gap between Low and Medium is roughly 25 to 40 FPS depending on resolution, while the gap between High and Ultra is much smaller, ranging from 4.6 FPS at 4K to 6.6 FPS at 1080p. This compression at the top settings tier is typical of a GPU that is nearing its throughput ceiling, and it confirms that the Ultra preset is not optimized for this hardware combination. The 4K Ultra result of 54.9 FPS is the only measured value below 55 FPS, and it serves as a warning that maxing out the game at 4K will introduce stutter. The 1440p and 1080p results all exceed 79 FPS, which is well within the smooth range for simulation.
