Microsoft Flight Simulator

The AMD Ryzen 5 7400F paired with the AMD Radeon RX 7900 XT lands at rank 489 out of 2996 tested combos in Microsoft Flight Simulator. That places this configuration in the top 16.3% of all tested systems, a strong position for a demanding flight simulator that stresses both the CPU and GPU heavily. The ranking reflects a balanced pairing where neither component holds the other back significantly at most settings, though the data reveals some interesting bottlenecks at the extremes of resolution and quality presets. For a simulator that frequently becomes a CPU-bound exercise in dense urban areas and a GPU-bound one at 4K, this combo sits in a sweet spot for high-refresh 1440p gaming and playable 4K.

How This Combo Ranks

The 489th rank out of 2,996 combos places this system in the upper echelon of tested configurations. More importantly, the rank is not a fluke of a single favorable setting; the measured FPS across all twelve data points shows consistent performance that scales predictably with resolution and quality. The CPU's average benchmark score of 32,750 sits at the 83rd percentile against all CPUs, and the GPU's average score of 13,745 puts it at the 55th percentile against all GPUs. The GPU percentile appears modest because the RX 7900 XT is compared against a database that includes many workstation and mobile parts; in gaming-specific workloads, its 20 GB of VRAM and 800.0 GB/s of bandwidth carry it far up the charts.

The nearest rivals for the CPU show how tight the competition is at this level. The Intel Core i5-14600T scores 32,707 (0.1% behind), the Intel Core Ultra 7 155H scores 32,697 (0.2% behind), and the AMD Ryzen 7 PRO 6850H scores 32,812 (0.2% ahead). These deltas are within run-to-run variance, meaning the 7400F trades blows with these parts in synthetic tests. For the GPU, the nearest rival list is more peculiar: the AMD Radeon 660M (13,812) and NVIDIA RTX A2000 Mobile (13,821) sit just 0.5% behind, while the AMD Radeon RX 570X (13,871) is 0.9% behind. The only modern gaming GPU in that list, the AMD Radeon RX 9070 XT (13,543), is 1.5% behind, which suggests the 7900 XT's average benchmark score is dragged down by older DirectX tests that do not reflect its modern architecture.

CPU Role

The Ryzen 5 7400F is a 6-core, 12-thread processor built on the Zen 4 Raphael architecture using TSMC's 5 nm process. It runs at a 3.70 GHz base clock and boosts to 4.70 GHz, with 32 MB of shared L3 cache and 1 MB of L2 per core. For Microsoft Flight Simulator, the single-core performance is critical because the simulation engine's main thread handles physics, flight model calculations, and AI traffic. The Cinebench R23 single-core score of 3,072 and the PassMark single-thread score of 3,689 indicate strong per-core performance that keeps the main thread from becoming a bottleneck at moderate settings.

Multi-core performance matters for the background tasks: terrain streaming, weather simulation, and airport ground traffic. The Cinebench R23 multi-core score of 21,765 and the PassMark multi-thread score of 25,645 show a capable 6-core part that handles these loads without choking. The data confirms this in the FPS results: at 1080p Low, the combo hits 177 FPS, which is high enough that even a slightly stronger CPU might not push much further. The 65 W TDP and dual-channel DDR5 memory support with 83.2 GB/s bandwidth provide adequate feeding for the GPU without introducing CPU-side memory bottlenecks.

The 7400F's 83rd percentile ranking against all CPUs reflects its position as a strong mid-range part that outperforms many older high-core-count processors in gaming workloads. The nearest rival comparison shows it trades blows with the Core Ultra 7 155H, a mobile chip with more cores, but the 7400F's higher boost clock and lower latency Zen 4 architecture give it an edge in the single-threaded tasks that dominate flight sim. The data suggests that at 1080p and 1440p, the CPU is doing its job without becoming the limiting factor, but at 4K, the GPU takes over as the primary constraint.

GPU Role

The RX 7900 XT is a Navi 31 chip based on RDNA 3.0, built on TSMC's 5 nm process with 57,700 million transistors. It features 5,376 shading units, 336 TMUs, and 192 ROPs, with 84 ray-tracing cores. The boost clock is 2,394 MHz, and the memory runs at 20 Gbps effective across a 320-bit bus, yielding 800.0 GB/s of bandwidth. The 20 GB of GDDR6 VRAM is a major asset for Microsoft Flight Simulator, which loads massive photogrammetry textures and high-resolution terrain data. At 4K Ultra, the game can exceed 16 GB of VRAM in dense areas, so the 7900 XT's 20 GB buffer prevents texture pop-in and stutter.

The GPU's FP32 throughput of 51.48 TFLOPS and texture rate of 804.4 GTexel/s provide ample compute for the simulator's rendering pipeline. The pixel rate of 459.6 GPixel/s means the GPU can fill 4K frames quickly when the CPU feeds it enough draw calls. The PassMark G3D score of 29,009 and 3DMark Steel Nomad DX12 score of 5,623 indicate strong DirectX 12 performance, which is the primary API used by the current version of Flight Simulator. The GPU's 55th percentile against all GPUs is misleading in this context because that percentile includes integrated graphics and older cards; against modern discrete GPUs, the 7900 XT is a top-tier part.

The GPU's nearest rivals in the benchmark database are mostly integrated or older parts, which highlights how the average benchmark score is skewed. The RX 7900 XT's 1.5% lead over the RX 9070 XT in average score is interesting because the latter is a newer part, but the 7900 XT's higher memory bandwidth and wider bus give it an edge in bandwidth-sensitive workloads like flight sim. The data shows the GPU is not the bottleneck at 1080p Low (177 FPS), but it becomes the limiting factor at 4K Ultra (59 FPS), where the CPU has more headroom.

Measured FPS Breakdown

At 1920x1080, the combo delivers strong performance across all settings. Low averages 177 FPS, which is fluid for any monitor. Medium drops to 138 FPS with a minimum of 117 and maximum of 159, showing consistent frame pacing. High averages 104 FPS, and Ultra averages 99 FPS. The gap between High and Ultra is only 5 FPS, suggesting that the Ultra preset's additional visual effects are not heavily taxing the GPU at this resolution. The 1080p results indicate that the CPU is capable of driving high frame rates, but the GPU is also not struggling — the delta from Low to Ultra is 78 FPS, which is a wide spread.

At 2560x1440, the performance scales as expected. Low averages 143 FPS, Medium 111 FPS (minimum 95, maximum 128), High 84 FPS, and Ultra 80 FPS. The drop from 1080p to 1440p at each setting is roughly 20-25%: Low goes from 177 to 143 (-19%), Medium from 138 to 111 (-20%), High from 104 to 84 (-19%), and Ultra from 99 to 80 (-19%). This consistent scaling suggests the GPU is handling the increased pixel count without a sudden bottleneck, and the CPU is keeping up with the higher resolution's draw call requirements.

At 3840x2160, the picture changes. Low averages 106 FPS, Medium 82 FPS (minimum 70, maximum 94), High 62 FPS, and Ultra 59 FPS. The drop from 1440p to 4K is steeper: Low goes from 143 to 106 (-26%), Medium from 111 to 82 (-26%), High from 84 to 62 (-26%), and Ultra from 80 to 59 (-26%). This consistent 26% drop across all settings indicates the GPU's pixel throughput is becoming the limiting factor, as the CPU has more headroom at 4K but the GPU's fill rate and memory bandwidth are stretched. The 4K Ultra result of 59 FPS is just shy of the 60 FPS target, and the 4K High result of 62 FPS barely crosses it.

Resolution Scaling

The FPS data reveals a clear pattern: from 1080p to 1440p, the performance drops by about 19-20% across all settings. From 1440p to 4K, the drop is steeper at 26% across all settings. This asymmetry tells us something important about the limiting component. At 1080p and 1440p, the CPU is still able to feed the GPU enough draw calls to keep frame rates high, and the GPU's 800.0 GB/s bandwidth is sufficient for the lower pixel counts. The 20% drop from 1080p to 1440p is expected from the 2.25x increase in pixel count, but the actual FPS drop is less than the pixel count increase, suggesting the GPU is not fully saturated at 1080p.

The move to 4K (a 2.25x increase from 1440p) results in a 26% FPS drop, which is closer to the pixel count ratio but still not linear. This indicates that at 4K, the GPU's shading units and ROPs are working near their limit, while the CPU has spare capacity. The fact that the 4K Low result (106 FPS) is higher than the 1440p High result (84 FPS) shows that lowering settings at 4K can recover performance, but the CPU is not the primary limiter at 4K — the GPU is. The 20 GB VRAM buffer is likely not the issue at 4K, as the game fits within it, but the 459.6 GPixel/s pixel rate is what caps the frame rate.

The data suggests that if you want to play at 4K, you should expect the GPU to be the bottleneck. At 1080p and 1440p, the system is more balanced, with the CPU and GPU sharing the load. The 26% drop from 1440p to 4K is consistent across Low, Medium, High, and Ultra, which means the GPU's rasterization pipeline is the limiting factor regardless of visual complexity. This is typical for a flight simulator where the rendering load is dominated by terrain and cloud rendering, which scale with resolution.

Settings Recommendations

For the best experience per the measured rows, the sweet spot depends on your target resolution and refresh rate. At 1080p, the High preset at 104 FPS is the best balance of visual quality and frame rate — Ultra only adds 5 FPS less (99 FPS) but likely includes heavier shadow and reflection effects that are not worth the small performance loss. If you have a 144 Hz monitor, Medium at 138 FPS is the better choice, as it stays above 120 FPS and the minimum of 117 FPS keeps it smooth. At 1080p, the CPU is not the bottleneck, so you can push settings without worrying about stutter.

At 1440p, the High preset at 84 FPS is the recommended choice if you have a 60-75 Hz monitor. Ultra at 80 FPS is nearly identical in frame rate, so if you want the extra visual fidelity, it is a free upgrade. However, if you have a 144 Hz monitor at 1440p, you must drop to Low (143 FPS) or Medium (111 FPS) to get above 100 FPS. Medium's minimum of 95 FPS is acceptable for most players, but the 111 FPS average is not enough for a 144 Hz display's full refresh. The data shows that 1440p High is the best quality-per-frame-rate ratio, as the 84 FPS average is well above the 60 FPS threshold and the visual quality is significantly better than Low.

At 4K, the situation is more constrained. The Ultra preset at 59 FPS is just below the 60 FPS target, and the High preset at 62 FPS barely crosses it. For a 60 Hz 4K display, High is the better choice because it provides a 62 FPS average with a likely smoother experience, while Ultra's 59 FPS may cause occasional dips below 60. Medium at 82 FPS is the best option if you want headroom above 60 FPS, and the minimum of 70 FPS ensures no drops below the refresh rate. Low at 106 FPS is overkill for a 60 Hz display, but it could be useful for a 120 Hz 4K monitor, though the visual quality loss is substantial.

The overall recommendation is to target 1440p High for the best balance of visual fidelity and frame rate, as the 84 FPS average is smooth and the system has headroom. If you have a 4K display, choose High or Medium rather than Ultra, as the 3 FPS difference between High and Ultra at 4K is not worth the visual cost. At 1080p, the system is over-powered for most displays, so you can comfortably use Ultra or High without any concern. The data shows that the combo is best suited for 1440p gaming, where it delivers high frame rates at high settings, and it can handle 4K at high settings if you are willing to accept around 60 FPS.
