Microsoft Flight Simulator

The pairing of the Intel Core i7-13700K with the AMD Radeon RX 6650 XT produces a distinctly GPU-limited experience in Microsoft Flight Simulator, though the degree of that limitation shifts dramatically depending on resolution. The measured frame rates show a clear pattern: the RX 6650 XT is the primary bottleneck at 4K, while the i7-13700K’s strong single-thread performance keeps the system competitive at lower resolutions. This combination ranks 1171 out of 1795 tested combos in the game, placing it in the lower-middle tier of the database, which aligns with the GPU’s 72nd percentile standing among all graphics cards. The CPU, by contrast, sits at the 93rd percentile, underscoring that the graphics card is the limiting factor in this pairing.

Resolution Scaling

The frame rate drop from 1080p to 4K is steep and consistent across all settings, revealing a system where the RX 6650 XT’s 8 GB of GDDR6 memory and 128-bit bus width are working hard. At Low settings, 1080p yields 105.8 FPS, but 1440p drops to 83.6 FPS, and 4K falls to 59 FPS — a 44% reduction from 1080p to 4K. The pattern intensifies at High settings: 58.9 FPS at 1080p, 47.3 FPS at 1440p, and 33.5 FPS at 4K, representing a 43% loss from the lowest to highest resolution. Medium settings show similar scaling, with 80.4 FPS at 1080p dropping to 68.1 FPS at 1440p and 47.4 FPS at 4K.

Ultra settings tell the most revealing story about the limiting component. At 1080p, Ultra produces 60.7 FPS, which is only 1.8 FPS higher than High at the same resolution — a negligible gain that suggests the CPU is already providing all the geometry and draw-call throughput the GPU can handle. At 4K Ultra, the average falls to 34.8 FPS, a 43% drop from 1080p Ultra. This scaling behavior indicates that the RX 6650 XT’s pixel throughput and memory bandwidth are the constraints; the 10.79 TFLOPS of FP32 compute and 280.3 GB/s bandwidth simply cannot sustain high frame rates at 4K. The i7-13700K, with its 5.40 GHz boost clock and 30 MB of shared L3 cache, is not the bottleneck here — the data shows that reducing resolution consistently yields proportional FPS gains, which is the hallmark of a GPU-limited scenario.

Settings Recommendations

The measured rows suggest that Medium settings offer the most balanced experience across all resolutions. At 1080p, Medium delivers 80.4 FPS, which is comfortably above the 60 FPS threshold and only 25.4 FPS below Low — a reasonable trade-off for visual fidelity. At 1440p, Medium produces 68.1 FPS, which remains playable, while 4K Medium falls to 47.4 FPS, still smooth enough for a flight simulator where precise control matters more than twitch response. High settings are viable only at 1080p, where 58.9 FPS is borderline but usable; at 1440p High drops to 47.3 FPS, and at 4K High collapses to 33.5 FPS, which is rough for a game that requires steady visual feedback during landing approaches.

Ultra settings are not recommended for this pairing. The 1080p Ultra result of 60.7 FPS is only 1.8 FPS faster than High, meaning the extra visual detail is nearly free in performance terms, but the 4K Ultra figure of 34.8 FPS is the worst measured result in the entire dataset. Low settings, while producing the highest frame rates (105.8 FPS at 1080p, 83.6 FPS at 1440p, 59 FPS at 4K), sacrifice too much visual quality for a simulator that relies heavily on scenery readability. The sweet spot is clearly Medium: it provides a 70% uplift over High at 1080p (80.4 vs 58.9 FPS), a 44% uplift at 1440p (68.1 vs 47.3 FPS), and a 41% uplift at 4K (47.4 vs 33.5 FPS), all while maintaining frame rates that are smooth enough for the genre.

GPU Role

The AMD Radeon RX 6650 XT’s specifications directly explain its behavior in Microsoft Flight Simulator. The GPU features a base clock of 2055 MHz and a boost clock of 2635 MHz, with a game clock of 2410 MHz, and its 2048 shading units are arranged in a configuration that yields a texture rate of 337.3 GTexel/s and a pixel rate of 168.6 GPixel/s. The 8 GB of GDDR6 memory on a 128-bit bus provides 280.3 GB/s of bandwidth, which is the critical constraint at higher resolutions. Flight Simulator streams vast amounts of terrain and photogrammetry data, and the RX 6650 XT’s memory subsystem is clearly taxed at 4K, where even Medium settings drop below 50 FPS.

The 32 ray accelerators on the Navi 23 chip (RDNA 2.0 architecture) are largely irrelevant for this title, as the measured FPS data shows no evidence of ray tracing workload. The GPU’s transistor count of 11,060 million on a 7 nm TSMC process gives it a density of 46.7M transistors per square millimeter, which is efficient but does not overcome the memory bandwidth wall. The card’s 176 W TDP and PCIe 4.0 x8 interface are adequate for the workload, but the bus width is the limiting factor. Benchmark results place the RX 6650 XT at the 72nd percentile among all GPUs, with an average benchmark score of 29024. Its nearest rivals include the AMD Radeon RX 6800M (deltaPct 0), the AMD Radeon RX 470 (deltaPct 0.1), and the Intel Arc A370M (deltaPct -0.5), which cluster tightly around this performance level — but none of those rivals are tested in this specific game configuration, so the observed FPS figures stand alone.

Measured FPS Breakdown

At 1920x1080, the full settings range is usable. Low settings produce 105.8 FPS, which is the highest measured result in the entire dataset. Medium drops to 80.4 FPS, High to 58.9 FPS, and Ultra to 60.7 FPS — the Ultra figure being slightly higher than High, which is an anomaly likely explained by variable scene complexity in the benchmark run. At 2560x1440, the pattern becomes more consistent: Low delivers 83.6 FPS, Medium 68.1 FPS, High 47.3 FPS, and Ultra 45.9 FPS. The gap between High and Ultra narrows to 1.4 FPS at 1440p, suggesting diminishing returns from the highest preset. At 3840x2160, the results are as follows: Low achieves 59 FPS, Medium 47.4 FPS, High 33.5 FPS, and Ultra 34.8 FPS. The High and Ultra figures at 4K are nearly identical (a 1.3 FPS difference), which indicates that the GPU is fully saturated regardless of the extra detail Ultra adds.

The most striking data point is the 1080p Low result of 105.8 FPS versus the 4K Low result of 59 FPS — a 44% reduction that persists across all settings. This consistency confirms that the RX 6650 XT’s memory bandwidth, not the CPU’s processing power, dictates the ceiling. The i7-13700K’s 3DMark scores (10717 for 16 threads, 12412 for max threads, 1136 for single thread) and Cinebench R23 results (39000 multicore, 5505 singlecore) are far above what this game demands at any resolution, and the CPU’s nearest rivals — the Intel Core i7-13700KF (deltaPct -0.1), AMD EPYC 4364P (deltaPct 0.3), and Intel Core i9-12900F (deltaPct 0.4) — all sit within a fraction of a percent of its average score, confirming it is not the differentiator here.

FAQ

Q: What is the best resolution for this CPU-GPU combo in Microsoft Flight Simulator?

A: The data shows 1920x1080 is the only resolution where all settings remain playable, with Low at 105.8 FPS, Medium at 80.4 FPS, High at 58.9 FPS, and Ultra at 60.7 FPS. At 1440p, only Low and Medium stay above 60 FPS (83.6 and 68.1 FPS respectively), while 4K drops below 60 FPS even at Low (59 FPS).

Q: How much FPS does upgrading from High to Ultra cost?

A: The penalty is minimal. At 1080p, Ultra is actually 1.8 FPS faster than High (60.7 vs 58.9 FPS). At 1440p, Ultra is 1.4 FPS slower (45.9 vs 47.3 FPS). At 4K, Ultra is 1.3 FPS faster (34.8 vs 33.5 FPS). The performance difference between High and Ultra is negligible, so Ultra is effectively free.

Q: Is the Intel Core i7-13700K bottlenecking the AMD Radeon RX 6650 XT?

A: No. The CPU ranks at the 93rd percentile among all processors with an average benchmark score of 47282, while the GPU sits at the 72nd percentile. The consistent FPS scaling from 1080p to 4K indicates the GPU is the limiting component; the CPU’s 3DMark single-thread score of 1136 and Cinebench R23 single-core score of 5505 are more than sufficient for this title.

Q: What FPS can I expect at 1440p with Medium settings?

A: The measured average is 68.1 FPS. This is the highest playable setting at 1440p that maintains smooth performance, as High drops to 47.3 FPS and Ultra to 45.9 FPS. Low yields 83.6 FPS at 1440p but sacrifices significant visual detail.

Q: Can this system handle 4K gaming in Microsoft Flight Simulator?

A: Only at Low settings, which produce 59 FPS at 3840x2160. Medium drops to 47.4 FPS, High to 33.5 FPS, and Ultra to 34.8 FPS. The RX 6650 XT’s 8 GB memory and 280.3 GB/s bandwidth are insufficient for high-detail 4K in this simulator.

Q: How does the RX 6650 XT compare to its nearest rivals in overall GPU performance?

A: The GPU’s average benchmark score is 29024, placing it at the 72nd percentile. Its nearest rivals are the AMD Radeon RX 6800M (average score 29011, deltaPct 0), the AMD Radeon RX 470 (average score 28996, deltaPct 0.1), and the Intel Arc A370M (average score 29175, deltaPct -0.5). These scores are effectively identical, but none of these rivals have measured FPS data for this specific game configuration.
