Microsoft Flight Simulator

Microsoft Flight Simulator presents an unusual workload where the AMD Ryzen 7 9800X3D and AMD Radeon RX 6600 XT combination produces a clear hierarchy of playable settings. The measured data shows that this pairing is capable of smooth performance, but only when the graphical load is carefully managed. The 8-core, 16-thread processor with its 96 MB of shared L3 cache demonstrates why CPU headroom matters in a simulation, while the 8 GB Radeon RX 6600 XT frequently becomes the constraining factor at higher resolutions. The results across 12 tested configurations reveal that this is a system which rewards users who prioritize frame rate stability over maximum visual fidelity.

Settings Recommendations

The benchmark data points to Medium as the optimal preset for this hardware combination, particularly at 1440p and 1080p. At 1920x1080 with Medium settings, the system produces 76.3 FPS average, which is a substantial margin above the 57.0 FPS seen at High. The jump from Medium to High costs 19.3 FPS at 1080p, while the jump from Low to Medium only costs 21.0 FPS but delivers significantly better visuals. The sweet spot is clear: Medium offers 76.3 FPS at 1080p and 61.8 FPS at 1440p, both of which are comfortably playable.

At 4K, the situation changes dramatically. The Ultra preset at 3840x2160 yields only 34.0 FPS average, which is marginal for a flight simulator where smooth panning is essential. Even High at 4K struggles, hitting 32.6 FPS. The only 4K preset that approaches playability is Low at 56.5 FPS, but that sacrifices too much visual detail for most users. The data suggests that 4K is not a realistic target for this combo unless users are willing to accept Low settings. For the best balance of visual quality and performance, Medium at 1440p (61.8 FPS) or Medium at 1080p (76.3 FPS) are the recommended configurations.

CPU Role

The Ryzen 7 9800X3D brings substantial processing power to this pairing, and the benchmark results indicate that the CPU is rarely the limiting factor at lower resolutions. With a base clock of 4.70 GHz boosting to 5.20 GHz, the processor's single-thread performance is exceptional, as evidenced by its 3dmark_single_thread score of 1212. In a simulation like Microsoft Flight Simulator, which relies heavily on physics calculations and scenery loading, this single-core strength matters. The processor's 96 MB of shared L3 cache is particularly relevant, as flight simulators often access large datasets for terrain and aircraft models.

The CPU's multi-threaded capabilities are equally strong, with a 3dmark_max_threads score of 10067 and a cinebench_r23_multicore score of 34004. However, the measured FPS data suggests that at 1080p, the GPU becomes the bottleneck even at Medium settings. The 97.3 FPS at Low 1080p indicates the CPU can feed frames well above what the GPU can render at higher settings. The processor's 90th percentile ranking among all CPUs and its average benchmark score of 37780 place it near rivals like the Intel Core i5-13600KF, which scores 38028 (a -0.7% delta). This suggests the CPU has ample headroom for future GPU upgrades without becoming obsolete.

GPU Role

The Radeon RX 6600 XT is the component that most directly determines playability in this configuration. With 8 GB of GDDR6 memory on a 128-bit bus delivering 256.0 GB/s bandwidth, the GPU has enough capacity for 1080p and 1440p gaming but struggles with 4K textures. The measured FPS deltas between settings confirm this: at 1440p, dropping from High (47.7 FPS) to Medium (61.8 FPS) provides a 14.1 FPS improvement, while dropping to Low (82.9 FPS) adds another 21.1 FPS. This pattern shows a GPU that is heavily taxed by higher quality presets.

The GPU's 71st percentile ranking among all GPUs, with an average benchmark score of 27985, places it just ahead of the NVIDIA GeForce GTX 980 Ti (27956, +0.1% delta) but behind the NVIDIA GeForce RTX 3070 (28238, -0.9% delta). The 32 ray tracing cores and 2048 shading units are not utilized heavily in this sim, but the raw fill rate matters. The 165.7 GPixel/s pixel rate and 331.4 GTexel/s texture rate are adequate for 1080p Medium, but the 4K results show the GPU's limits. The 34.0 FPS at 4K Ultra versus 53.7 FPS at 1080p Ultra represents a 36.7% performance drop, indicating that the GPU's 8 GB frame buffer becomes a critical constraint at higher resolutions.

How This Combo Ranks

Among 1795 tested combinations in Microsoft Flight Simulator, this pairing ranks 1364th. That places it in the bottom quarter of all configurations tested, which is notable given the CPU's strength. The data implies that the RX 6600 XT significantly holds back the Ryzen 7 9800X3D in this particular game. The CPU's performance metrics are elite — its 3dmark_8_threads score of 8252 and cinebench_r23_singlecore score of 4800 demonstrate top-tier capability. Yet the combo rank of 1364 suggests that many systems with weaker CPUs but stronger GPUs outperform this pairing in actual flight sim scenarios.

This rank disparity between component quality and combo performance is the key finding. The CPU sits at the 90th percentile among all processors, while the GPU sits at the 71st percentile among all GPUs. When combined, the system should theoretically perform better than its 1364th rank suggests. The measured FPS data indicates that at 1080p Medium, the system achieves 76.3 FPS, which is respectable. However, the rank reflects that many competitors with more balanced pairings — or with GPUs that have more VRAM — achieve higher average frame rates across all tested settings.

Resolution Scaling

The FPS scaling from 1080p to 4K reveals where the bottleneck lies. At Medium settings, the system delivers 76.3 FPS at 1080p, 61.8 FPS at 1440p, and 47.3 FPS at 4K. This represents an 18.9% drop from 1080p to 1440p and a 38.0% drop from 1440p to 4K. The scaling is not linear, which suggests the GPU is the limiting factor. At Low settings, the drop is more severe: 97.3 FPS at 1080p drops to 82.9 FPS at 1440p (a 14.8% drop) and then to 56.5 FPS at 4K (a 31.8% drop from 1440p). The fact that Low settings at 4K still cannot reach 60 FPS, while 1080p Low achieves 97.3 FPS, points directly to the GPU's memory bandwidth and capacity constraints.

At Ultra settings, the pattern is even more telling. The system manages 53.7 FPS at 1080p, 43.6 FPS at 1440p, and 34.0 FPS at 4K. The consistent degradation across resolutions indicates that the GPU is working at its limits even at 1080p Ultra. The CPU, by contrast, shows no signs of being the constraint — the 3dmark_16_threads score of 10081 and the 89.6 GB/s memory bandwidth provide more than enough throughput for this game's CPU demands. The data suggests that users with 4K displays should either reduce settings to Low or consider a GPU upgrade.

Measured FPS Breakdown

At 1920x1080, the system delivers its highest frame rates. Low settings average 97.3 FPS, Medium averages 76.3 FPS, High averages 57.0 FPS, and Ultra averages 53.7 FPS. The gap between Medium and High is 19.3 FPS, while the gap between High and Ultra is only 3.3 FPS, suggesting diminishing returns at the top end.

At 2560x1440, performance remains respectable but drops noticeably. Low settings average 82.9 FPS, Medium averages 61.8 FPS, High averages 47.7 FPS, and Ultra averages 43.6 FPS. The Medium preset is the only one that maintains an average above 60 FPS, while Ultra falls 16.2 FPS below the Medium result.

At 3840x2160, the GPU struggles across all presets. Low settings average 56.5 FPS, Medium averages 47.3 FPS, High averages 32.6 FPS, and Ultra averages 34.0 FPS. Interestingly, High performs slightly worse than Ultra (32.6 vs 34.0), which may indicate variability in the test scenarios. None of the 4K presets achieve the 60 FPS threshold, and even Low falls short by 3.5 FPS.
