Microsoft Flight Simulator

Microsoft Flight Simulator is a notoriously demanding title, and the data for the AMD Ryzen 7 9850X3D paired with the AMD Radeon RX 7900 XT shows a system that is consistently capable of delivering smooth, playable frame rates across a wide range of resolutions and quality settings. The measured results indicate that this combination is well-balanced, though the scaling patterns reveal where each component’s influence is strongest.

Resolution Scaling

The frame rate progression from 1080p to 4K follows a clear and predictable pattern, with the most significant performance drop occurring when moving from 1440p to 2160p. At the High preset, the system delivers an average of 104 FPS at 1920x1080, which drops to 84 FPS at 2560x1440, and further to 62 FPS at 3840x2160. This represents an approximate 40% reduction in performance from 1080p to 4K, a substantial hit that is characteristic of a game that becomes heavily GPU-bound at higher resolutions.

The scaling data shows that the CPU is not the limiting factor in most scenarios. At 1080p with the Low preset, the system reaches 177 FPS, which is exceptionally high for a flight simulator. The fact that the Low preset at 1080p produces nearly double the frame rate of the Ultra preset at the same resolution (99 FPS) indicates that the GPU is doing the heavy lifting. When the resolution increases to 4K, the Low preset still manages 106 FPS, but the High and Ultra presets fall to 62 and 59 FPS respectively. This steep decline at 4K with higher settings suggests that the RX 7900 XT’s rendering capabilities, particularly its pixel throughput, are the primary constraint in this configuration.

Interestingly, the gap between Medium and High settings is relatively small at each resolution. At 1440p, Medium averages 111 FPS while High averages 84 FPS, a difference of 27 FPS. However, the gap between High and Ultra is much smaller: 84 FPS versus 80 FPS at 1440p, and 62 FPS versus 59 FPS at 4K. This pattern indicates that the Ultra preset introduces effects that are not proportionally more demanding, or that the GPU hits a performance ceiling where additional settings have diminishing returns. The data suggests that the CPU, with its 8 cores and 16 threads, provides a robust foundation that rarely bottlenecks the GPU, even at lower resolutions where the CPU workload is relatively heavier.

How This Combo Ranks

Within the database of tested CPU and GPU combinations for Microsoft Flight Simulator, this specific pairing holds a combo rank of 489 out of 2996 tested combos. This places the system in the top 16.3% of all tested configurations, which is a strong showing for a high-end desktop setup. The rank reflects the balanced nature of the pairing—neither component is dragging the other down, and the system is capable of handling the game’s demands at 4K with high settings.

The CPU’s individual benchmark scores are notably strong. The AMD Ryzen 7 9850X3D achieves a Cinebench R23 multi-core score of 22807 and a single-core score of 2228. Its average benchmark score is 58386, which places it in the 92nd percentile of all CPUs. When compared to its nearest rivals, the performance is nearly identical: it trails the Intel Xeon w5-2545 by only 0.2% and the AMD Ryzen AI 9 HX 470 by 0.7%, while leading the Intel Xeon Platinum 8260M by 0.1% and the Intel Core i9-14900 by 0.5%. These tiny margins indicate that the CPU is performing exactly as expected for its class, with no obvious anomalies.

The GPU, meanwhile, sits in the 55th percentile of all GPUs with an average benchmark score of 13745. Its nearest rivals include the AMD Radeon 660M, which is 0.5% slower, and the AMD Radeon RX 9070 XT, which is 1.5% faster. The RX 7900 XT’s performance in this game is consistent with its overall benchmark standing, and the combo rank of 489 reflects that the CPU’s strength helps boost the system above what the GPU alone might achieve. The data suggests that the CPU is the stronger component in this pairing, which is typical for a flight simulator that benefits from high single-thread performance.

GPU Role

The AMD Radeon RX 7900 XT is built on the RDNA 3.0 architecture and features 20 GB of GDDR6 memory on a 320-bit bus, providing a memory bandwidth of 800.0 GB/s. The GPU’s boost clock is 2394 MHz, with a game clock of 2025 MHz. These specifications are directly relevant to the measured frame rates, particularly at 4K where memory bandwidth and pixel throughput become critical. The GPU has 192 ROPs and a pixel rate of 459.6 GPixel/s, which helps explain why the system can maintain playable frame rates at 4K even with demanding settings.

The VRAM capacity of 20 GB is more than sufficient for Microsoft Flight Simulator, which is known for loading large textures and terrain data. The data shows that even at 4K Ultra, the system averages 59 FPS, which indicates that the GPU is not running out of memory. If VRAM were a constraint, the frame rates would likely be much lower or inconsistent. The measured results show a smooth progression from Low to Ultra settings, with no sudden drops that would indicate memory swapping or other VRAM-related issues.

The GPU’s compute capabilities, including its 5376 shading units and 84 RT cores, contribute to the overall rendering performance. The FP32 throughput of 51.48 TFLOPS provides ample raw compute power, but the game’s performance at 4K Ultra (59 FPS) suggests that the GPU is working near its limits. The fact that the Low preset at 4K achieves 106 FPS, while the High preset drops to 62 FPS, demonstrates that the GPU’s fixed-function hardware, such as texture units and ROPs, is the bottleneck at higher quality settings. The data indicates that the RX 7900 XT is well-suited for 1440p gaming and can handle 4K with adjusted settings, but that Ultra settings at 4K will push it to its limits.

Settings Recommendations

Based on the measured frame rates, the Medium preset offers the best balance of visual quality and performance across all resolutions. At 1080p, Medium delivers an average of 138 FPS with a minimum of 117 FPS, ensuring a consistently smooth experience. At 1440p, Medium averages 111 FPS with a minimum of 95 FPS, which is still well above the 60 FPS threshold for smooth gameplay. Even at 4K, Medium maintains an average of 82 FPS with a minimum of 70 FPS, making it the only preset that provides a comfortable margin above 60 FPS at that resolution.

The High preset is viable for users who prioritize visual fidelity over raw frame rates, but it comes with a significant performance cost. At 1080p, High averages 104 FPS, which is acceptable, but at 1440p it drops to 84 FPS, and at 4K it falls to 62 FPS. The Ultra preset, while offering the best visuals, only achieves 99 FPS at 1080p and 80 FPS at 1440p, with a marginal 59 FPS at 4K. For most users, the Medium preset provides a superior experience because it maintains higher minimum frame rates, which are crucial for a simulation game where smoothness is more important than absolute visual fidelity.

The Low preset is not recommended for this hardware, as it achieves 177 FPS at 1080p and 143 FPS at 1440p, which are frame rates far beyond what is necessary for a flight simulator. The visual quality loss is not worth the performance gain, especially since Medium already provides frame rates well above 60 FPS. The data clearly shows that Medium is the sweet spot for this combination, offering a 33% performance increase over High at 4K while still delivering a playable and visually appealing experience.

Measured FPS Breakdown

At 1920x1080, the system delivers its highest frame rates. Low settings produce an average of 177 FPS, while Medium settings average 138 FPS with a minimum of 117 and a maximum of 159. High settings average 104 FPS, and Ultra settings average 99 FPS. The difference between High and Ultra is only 5 FPS, suggesting that the Ultra preset’s additional effects are not heavily taxing the GPU at this resolution.

Moving to 2560x1440, the performance drops are more pronounced. Low settings average 143 FPS, Medium averages 111 FPS with a minimum of 95 and a maximum of 128, High averages 84 FPS, and Ultra averages 80 FPS. The gap between Low and Medium is 32 FPS, while the gap between High and Ultra is only 4 FPS. This pattern indicates that the GPU is becoming more of a limiting factor as resolution increases.

At 3840x2160, the system shows its limits. Low settings average 106 FPS, Medium averages 82 FPS with a minimum of 70 and a maximum of 94, High averages 62 FPS, and Ultra averages 59 FPS. The jump from Low to Medium is 24 FPS, but the jump from Medium to High is 20 FPS, and from High to Ultra is only 3 FPS. This suggests that at 4K, the Ultra preset offers almost no additional performance penalty over High, but both are below the 60 FPS threshold that many users consider the minimum for a smooth experience. The Medium preset at 4K is the only setting that provides a comfortable margin above 60 FPS, with an average of 82 FPS.
