Microsoft Flight Simulator

CPU Role — cores, clocks, and how they relate to this game's results

The AMD Ryzen 5 7400F is a 6-core, 12-thread processor built on the Zen 4 architecture (Raphael) using TSMC's 5 nm process. It runs at a base clock of 3.70 GHz and boosts up to 4.70 GHz, with a 65 W TDP and support for DDR5 memory in a dual-channel configuration. The CPU's 32 MB of shared L3 cache and 1 MB per-core L2 cache are typical for the 7000 series desktop stack, and its 83.2 GB/s memory bandwidth is a direct result of the dual-channel DDR5 interface.

In the context of Microsoft Flight Simulator, a title that heavily emphasizes single-thread performance for flight model calculations, rendering thread scheduling, and terrain/scenery loading, this CPU's single-core capabilities are the primary driver of the simulation's "minimum frame" behavior. The benchmark data shows the Ryzen 5 7400F scores 3,072 points in Cinebench R23 single-core and 21,765 points in multi-core. For comparison, its nearest rivals in the aggregate CPU benchmark ranking include the Intel Core i5-14600T (average score 32,707, delta 0.1%), the Intel Core Ultra 7 155H (32,697, delta 0.2%), and the AMD Ryzen 7 PRO 6850H (32,812, delta -0.2%). The 7400F's average benchmark score of 32,750 places it in the 83rd percentile of all CPUs, meaning it outperforms the vast majority of processors in general-purpose workloads.

The 12 threads are sufficient for the game's background tasks like scenery streaming and AI traffic, but the observed frame rates across resolutions suggest the CPU is not the primary bottleneck in most settings. At 1080p Low, the combo achieves 121 FPS, which is a strong indicator that the CPU can feed the GPU well beyond typical flight sim needs. The processor's 5 nm process and 6,570 million transistors in a 71 mm² die contribute to efficient power delivery, though the game's performance is more dependent on clock speed and IPC than raw core count. The 7400F's boost behavior, up to 4.70 GHz, is what allows the simulation's main thread to maintain consistent frame pacing, as evidenced by the relatively small gap between High and Ultra settings at 1080p (71 vs 67 FPS).

GPU Role — VRAM, clocks, and how they relate to this game's results

The AMD Radeon RX 6700 XT is built on the RDNA 2.0 architecture (Navi 22 chip) using TSMC's 7 nm process, with 17,200 million transistors on a 335 mm² die. It features 2,560 shading units, 160 texture mapping units, and 64 render output units, along with 40 ray tracing cores. The card has a base clock of 2,321 MHz, a game clock of 2,424 MHz, and a boost clock of 2,581 MHz. Its memory subsystem consists of 12 GB of GDDR6 on a 192-bit bus, delivering 384.0 GB/s of bandwidth, with memory clocked at 2000 MHz (16 Gbps effective).

For Microsoft Flight Simulator, the GPU's role is primarily in rendering the detailed terrain, photogrammetry cities, aircraft models, and dynamic weather effects. The 12 GB VRAM is a significant asset at higher resolutions, as the game is known for loading large texture sets for ground scenery and aircraft liveries. The card's FP32 compute rating of 13.21 TFLOPS and texture rate of 413.0 GTexel/s provide adequate throughput for the game's deferred rendering pipeline. The pixel rate of 165.2 GPixel/s becomes more relevant at 4K, where the GPU is pushing more than 8 million pixels per frame.

The RX 6700 XT's benchmark scores show a mixed picture: it scores 19,786 in Passmark G3D and 9,336 in GPU compute, with a Passmark DirectX 12 score of 77. Its average benchmark score of 27,425 places it in the 72nd percentile of all GPUs. Nearest rivals include the NVIDIA GeForce RTX 4070 Mobile (average score 27,435, delta 0%), the NVIDIA GeForce RTX 3090 (27,565, delta -0.5%), and the AMD Radeon Pro Vega 20 (27,839, delta -1.5%). This positioning indicates the RX 6700 XT is a capable mid-range performer, though in Flight Simulator's specific workload, the data shows the GPU becomes the limiting factor at 4K Ultra settings, where average FPS drops to 40.

Resolution Scaling — how FPS drops from 1080p to 4K and what it says about the limiting component

The measured FPS data across resolutions reveals a clear scaling pattern that identifies where the bottleneck shifts. At 1080p, the combo delivers 121 FPS on Low, 94 FPS on Medium, 71 FPS on High, and 67 FPS on Ultra. Moving to 1440p, those numbers drop to 97 FPS on Low, 76 FPS on Medium, 57 FPS on High, and 54 FPS on Ultra. At 4K, the figures further decline to 72 FPS on Low, 56 FPS on Medium, 42 FPS on High, and 40 FPS on Ultra.

The percentage drops between 1080p and 1440p are roughly 20% for Low (121 to 97), 19% for Medium (94 to 76), 20% for High (71 to 57), and 19% for Ultra (67 to 54). Between 1440p and 4K, the drops are more pronounced: 26% for Low (97 to 72), 26% for Medium (76 to 56), 26% for High (57 to 42), and 26% for Ultra (54 to 40). The consistent ~20% drop from 1080p to 1440p and ~26% drop from 1440p to 4K across all settings indicates a GPU-bound scenario at higher resolutions.

The gap between Low and Ultra settings widens as resolution increases. At 1080p, the difference is 54 FPS (121 vs 67), at 1440p it is 43 FPS (97 vs 54), and at 4K it is 32 FPS (72 vs 40). This narrowing gap at higher resolutions suggests the GPU's raw pixel throughput becomes the dominant constraint, while at 1080p, the CPU has more headroom to allow setting changes to have a larger impact. The fact that 4K Low (72 FPS) is lower than 1080p Ultra (67 FPS) in absolute terms—though close—further confirms that resolution scaling has a more significant effect on performance than graphical preset changes at this hardware level.

Settings Recommendations — which preset gives the best experience per the measured rows

The data reveals that the Medium preset provides the most balanced experience across all resolutions, with the additional benefit of having measured minimum and maximum frame data. At 1080p Medium, the combo averages 94 FPS with a minimum of 80 and maximum of 108. At 1440p Medium, it averages 76 FPS with a minimum of 64 and maximum of 87. At 4K Medium, it averages 56 FPS with a minimum of 47 and maximum of 64.

The High preset offers a modest visual upgrade over Medium but costs roughly 25% performance at each resolution: 71 vs 94 at 1080p, 57 vs 76 at 1440p, and 42 vs 56 at 4K. Given that Flight Simulator is a slow-paced game where frame rates above 30 FPS are generally playable, the Medium preset at 1440p appears to be the sweet spot for this combination. It delivers 76 FPS on average, which is well above the typical 60 FPS target, and the 64 FPS minimum ensures smooth panning over dense scenery.

For users prioritizing visual fidelity, the Ultra preset at 1080p (67 FPS) is a viable option that stays above 60 FPS. However, at 1440p Ultra (54 FPS) and 4K Ultra (40 FPS), the frame rates dip below the 60 FPS threshold, which could be noticeable during fast descents or heavy weather effects. The Low preset, while achieving high frame rates (121 FPS at 1080p, 97 FPS at 1440p, 72 FPS at 4K), sacrifices too much of the game's visual appeal—the detailed terrain textures and aircraft models that define the experience—making it less desirable despite the performance headroom.
