Resolution Scaling

The measured FPS data for Microsoft Flight Simulator with the Intel Core i9-14900K and AMD Radeon RX 7600 shows a clear pattern of GPU-bound scaling as resolution increases. At 1080p Low, the combo produces 98.8 FPS, which drops to 80.2 FPS at 1440p Low and 58.2 FPS at 4K Low. That is a 41.1% reduction from 1080p to 4K at Low settings, indicating the GPU is the primary limiter even at the lowest quality preset.

The scaling becomes more pronounced at higher settings. At Ultra, the combo delivers 59.8 FPS at 1080p, 43.6 FPS at 1440p, and 33.7 FPS at 4K. The 4K Ultra result is 43.6% lower than the 1080p Ultra result, which is a larger relative drop than the Low preset's 41.1% decline. This suggests that as settings increase, the GPU workload grows disproportionately, reinforcing that the RX 7600 is the bottleneck in this pairing.

The Medium preset shows similar behavior: 77.9 FPS at 1080p, 63.8 FPS at 1440p, and 46 FPS at 4K. The 4K Medium result is 40.9% below the 1080p Medium result. High settings follow the same trend: 60.5 FPS at 1080p, 49.9 FPS at 1440p, and 35.9 FPS at 4K, with the 4K High result 40.7% lower.

Notably, the gap between 1080p and 1440p is smaller than the gap between 1440p and 4K across all settings. For example, at Low, 1080p to 1440p drops 18.8% (98.8 to 80.2 FPS), while 1440p to 4K drops 27.4% (80.2 to 58.2 FPS). This non-linear scaling is typical of a GPU that runs out of memory bandwidth or raw throughput at higher resolutions. The data clearly indicates that the CPU has ample headroom; the i9-14900K is not the limiting component in any resolution or settings combination.

How This Combo Ranks

The Intel Core i9-14900K and AMD Radeon RX 7600 combination ranks 1219 out of 1795 tested combos in Microsoft Flight Simulator. This places it in the 32.1st percentile of all tested configurations, meaning roughly two-thirds of tested combos deliver higher average FPS in this game. The rank is heavily influenced by the GPU, as the CPU alone sits in the 97th percentile among all processors.

The i9-14900K's own benchmark scores are exceptional: it achieves 49872 in Cinebench R23 multi-core and 7040 in single-core, with a Geekbench multi-core score of 20370 and single-core of 3064. Its Passmark multi-thread score is 58674, and its average benchmark score is 79824, placing it 0.3% below the AMD EPYC 7413 (80041) and 0.7% above the Intel Core i9-14900KF (79245). The data shows this CPU is a top-tier part, but the RX 7600's 63rd percentile GPU ranking (average benchmark score 20258) drags the combo down.

The RX 7600's nearest rivals in GPU benchmarks include the RX 7600 XT (0.6% higher score), the RX 460 (0.8% higher), the RTX 3070 Mobile (1.3% lower), and the Intel Arc B570 (1.5% lower). This tight clustering around the 20258 average score indicates that the GPU is a mid-range part, and its performance in Microsoft Flight Simulator is consistent with that positioning. The combo rank reflects this: the CPU is overqualified for the GPU, and the measured FPS is dictated almost entirely by the RX 7600's capabilities.

GPU Role

The AMD Radeon RX 7600 is built on the RDNA 3.0 architecture with the Navi 33 chip, fabricated on a 6 nm process at TSMC. It has 8 GB of GDDR6 memory on a 128-bit bus, providing 288.0 GB/s of bandwidth. The GPU features 2048 shading units, 128 texture mapping units, and 64 raster operation units, along with 32 ray tracing cores. Its base clock is 1720 MHz, with a game clock of 2250 MHz and a boost clock of 2655 MHz.

In Microsoft Flight Simulator, the 8 GB VRAM capacity and 288.0 GB/s bandwidth are the most relevant specifications. The game's high-resolution textures and complex scenery data place significant demands on memory bandwidth. The measured FPS at 4K Ultra (33.7 FPS) versus 4K Low (58.2 FPS) shows a 42.1% performance gap, which is consistent with a GPU that becomes bandwidth-starved at high settings and high resolution.

The GPU's compute capabilities are moderate: 21.75 TFLOPS FP32 and 43.50 TFLOPS FP16 (2:1). The pixel rate is 169.9 GPixel/s and the texture rate is 339.8 GTexel/s. These figures indicate a GPU that can handle 1080p gaming comfortably but struggles with 4K in a demanding simulation title. The benchmark data shows the GPU's Passmark G3D score is 16634, and its DirectX 12 score is 58, which aligns with its mid-range positioning.

The RX 7600's 63rd percentile ranking among all GPUs means it outperforms a majority of graphics cards, but it is not designed for 4K Ultra gaming in a title like Microsoft Flight Simulator. The data confirms this: 4K Ultra produces 33.7 FPS, which is below the 35.9 FPS at 4K High, and both are below the 46 FPS at 4K Medium. The GPU's role is the limiting factor at every resolution above 1080p Low.

Settings Recommendations

Based on the measured FPS data, the optimal settings for this combo depend on the target resolution. At 1080p, all four presets are playable: Low delivers 98.8 FPS, Medium delivers 77.9 FPS, High delivers 60.5 FPS, and Ultra delivers 59.8 FPS. The data shows that High and Ultra are nearly identical at 1080p, differing by only 0.7 FPS. This suggests that High is the most efficient choice at 1080p, as it provides nearly the same frame rate as Ultra with presumably lower GPU load.

At 1440p, the recommended preset is Medium, which produces 63.8 FPS. Low delivers 80.2 FPS but sacrifices visual quality, while High (49.9 FPS) and Ultra (43.6 FPS) fall below the 60 FPS threshold. The data shows that 1440p Medium offers the best balance of frame rate and visual fidelity among the measured options.

At 4K, the only playable preset is Low, which produces 58.2 FPS. Medium drops to 46 FPS, High to 35.9 FPS, and Ultra to 33.7 FPS. None of the higher presets at 4K reach 60 FPS, and all are below 50 FPS. For 4K gaming, the data indicates that Low is the only viable choice, and even then, the frame rate is just below the 60 FPS target.

The data suggests that this combo is best suited for 1080p gaming, where it can handle Ultra settings at nearly 60 FPS. For 1440p, Medium is the recommended preset. For 4K, users should expect to play at Low settings or consider lowering resolution. The measured FPS values show a clear trade-off: each step from Low to Ultra at any resolution costs between 20% and 30% performance.
