# How This Combo Ranks

The AMD Ryzen 9 9900X paired with the AMD Radeon RX 7700 XT achieves a combo rank of 1378 out of 3714 tested combinations in Microsoft Flight Simulator. This places the pairing in the 63rd percentile of all tested combos, indicating a solid mid-to-upper tier position for this flight simulator. The ranking reflects the balance between a high-end 12-core CPU and a mid-range GPU, which is a typical configuration for gamers seeking strong 1440p performance without chasing absolute 4K supremacy.

The CPU itself sits at the 92nd percentile among all processors, while the GPU ranks at the 67th percentile among all graphics cards. This disparity is notable: the processor is significantly stronger relative to its peers than the graphics card is relative to its own peer group. In a simulation title like Microsoft Flight Simulator, which is known for heavy single-threaded and multi-threaded CPU demands, this imbalance can actually work in the combo's favor at lower resolutions, but it creates a clear GPU bottleneck at 4K Ultra settings.

CPU Role

The AMD Ryzen 9 9900X brings 12 cores and 24 threads based on the Zen 5 architecture, built on a 4 nm process. Its base clock of 4.40 GHz and boost clock of 5.60 GHz provide substantial headroom for the simulation's complex flight dynamics and scenery processing. The CPU's 64 MB of L3 cache and dual-channel DDR5 memory support with 89.6 GB/s bandwidth ensure that the flight simulator's streaming terrain data has adequate bandwidth to avoid stuttering.

Benchmark data shows this processor excels in both single-threaded and multi-threaded workloads: it scores 2253 in Cinebench R23 single-core and 32172 in multi-core, with a Geekbench single-core score of 3010 and multi-core of 22174. These numbers place it among the top tier of desktop processors, with a percentile ranking of 92 versus all CPUs. Its nearest rivals in average benchmark score include the AMD EPYC 9015 (deltaPct -0.1%), the AMD EPYC 7313 (deltaPct 0.2%), the Intel Core i9-14900 (deltaPct -1.1%), and the Intel Xeon Platinum 8260M (deltaPct -1.4%). The Ryzen 9 9900X effectively trades blows with these server and high-end desktop parts, confirming its strength in CPU-bound scenarios.

In Microsoft Flight Simulator, the CPU's role is paramount for calculating physics, AI traffic, and the complex autogen scenery system. The measured FPS data shows that at 1080p Low settings, the combo reaches 139 FPS average, which is a strong indicator that the CPU can feed the GPU effectively at lower graphical loads. However, the single-thread performance, while excellent, is not the absolute fastest available, and the simulation's engine does not scale perfectly across all 24 threads. The 3DMark single-thread score of 1286 and 2-thread score of 2519 suggest that the first two cores are well-optimized, but the real-world flight sim performance will depend on how well the game utilizes the additional cores.

The CPU's 120W TDP and unlocked multiplier indicate it is designed for enthusiast overclocking, though the stock boost clock of 5.60 GHz already provides high frequency headroom. This is a desktop part on the AMD Socket AM5 platform with PCIe Gen 5 support, which future-proofs the system for faster storage and GPU interfaces. For Microsoft Flight Simulator, the combination of high clocks and 12 cores means the CPU is rarely the limiting factor at 1080p and 1440p settings, but at 4K Ultra, the GPU takes over as the primary constraint.

GPU Role

The AMD Radeon RX 7700 XT features 12 GB of GDDR6 memory on a 192-bit bus, delivering 432.0 GB/s of bandwidth. Its base clock is 1435 MHz, with a boost clock of 2544 MHz and a game clock of 2171 MHz. The GPU is built on the RDNA 3.0 architecture with 3456 shading units, 216 texture mapping units, and 96 raster operation pipelines, along with 54 ray tracing cores. This configuration provides 35.17 TFLOPS of FP32 compute performance and a pixel rate of 244.2 GPixel/s.

The GPU's benchmark results place it at the 67th percentile among all graphics cards, with an average score of 22549. Its nearest rivals in average benchmark score are the NVIDIA GeForce RTX 5060 Mobile (deltaPct 0.5%), the NVIDIA GeForce RTX 4060 Mobile (deltaPct -0.8%), the NVIDIA GeForce RTX 2080 (deltaPct -1.5%), and the AMD Radeon RX 5700 (deltaPct 1.7%). This places the RX 7700 XT in a competitive position against last-generation high-end cards and current-generation mid-range mobile parts, but it is not a top-tier performer in the absolute sense.

In Microsoft Flight Simulator, the GPU's role is to render the detailed cockpit, terrain textures, and lighting effects. The 12 GB VRAM is sufficient for 1080p and 1440p Ultra settings, but at 4K with High or Ultra presets, the memory bandwidth and compute power become limiting factors. The measured FPS shows that at 4K Ultra, the combo drops to 46 FPS average, which is playable but not smooth by modern standards. At 1080p Low, the GPU is less stressed, allowing the CPU to push the frame rate to 139 FPS average.

The RDNA 3.0 architecture supports DirectX 12 Ultimate, which is important for the flight simulator's use of DirectX 12 features. The GPU's 54 ray tracing cores are present, but Microsoft Flight Simulator's ray tracing implementation is not heavily utilized, so the rasterization performance is the primary driver of results. The 5 nm process node from TSMC keeps power consumption at a 245W TDP, with a suggested 550W PSU, making it a reasonable choice for mid-range builds.

Measured FPS Breakdown

At 1080p resolution, the combo delivers strong performance across all settings presets. The Low preset achieves 139 FPS average, Medium reaches 108 FPS with a minimum of 92 and maximum of 124, High hits 81 FPS, and Ultra drops to 77 FPS. These numbers indicate that at 1080p, the system is largely CPU-bound at lower settings, with the GPU becoming more relevant as the preset increases. The gap between Low and Ultra is 62 FPS, which is a significant reduction but still leaves the Ultra preset comfortably above 60 FPS.

Moving to 1440p, the performance scales down as expected. The Low preset averages 112 FPS, Medium averages 87 FPS with a minimum of 74 and maximum of 100, High averages 65 FPS, and Ultra averages 62 FPS. At this resolution, the Medium preset offers the best balance between visual fidelity and smoothness, staying above 60 FPS with a reasonable minimum. The High and Ultra presets are close together, with only 3 FPS separating them, suggesting that the GPU is becoming the limiting factor at this resolution.

At 4K (3840x2160), the performance drops more dramatically. The Low preset averages 82 FPS, Medium averages 64 FPS with a minimum of 55 and maximum of 74, High averages 48 FPS, and Ultra averages 46 FPS. The jump from Low to Medium is 18 FPS, while the jump from Medium to High is 16 FPS, and from High to Ultra is only 2 FPS. This pattern indicates that the GPU is heavily taxed at 4K, and the difference between High and Ultra presets is negligible in terms of frame rate, suggesting a VRAM or compute bottleneck.

Resolution Scaling

The FPS scaling from 1080p to 4K reveals where the bottleneck lies. At Low settings, the combo drops from 139 FPS at 1080p to 112 FPS at 1440p (a 19% reduction) and then to 82 FPS at 4K (a further 27% reduction from 1440p). This scaling pattern is typical of a system where the GPU begins to take over as the limiting factor at higher resolutions, but the CPU still has enough headroom to maintain high frame rates at lower settings.

At Medium settings, the scaling is similar: 108 FPS at 1080p, 87 FPS at 1440p (a 19% drop), and 64 FPS at 4K (a 26% drop from 1440p). The consistency of these percentage drops suggests a balanced system where neither component is severely underpowered for the target resolution.

At High settings, the drops become more pronounced: 81 FPS at 1080p, 65 FPS at 1440p (a 20% drop), and 48 FPS at 4K (a 26% drop from 1440p). The 4K High setting falls below 60 FPS, indicating that the GPU is no longer able to keep up with the increased pixel count and graphical demands.

At Ultra settings, the scaling is the most severe: 77 FPS at 1080p, 62 FPS at 1440p (a 19% drop), and 46 FPS at 4K (a 26% drop from 1440p). The fact that High and Ultra perform nearly identically at 4K (48 vs 46 FPS) strongly suggests that the RX 7700 XT's 12 GB VRAM or its compute resources are exhausted, and further graphical increases yield diminishing returns.

The overall pattern indicates that the CPU is the primary driver at 1080p, while the GPU becomes the limiting factor as resolution increases. At 4K, the GPU is clearly the bottleneck, as evidenced by the small performance gap between High and Ultra presets. For users targeting 4K, the data suggests that Medium settings provide the best playable experience, while 1440p Medium or High offers a good balance.

Settings Recommendations

Based on the measured FPS data, the optimal settings preset depends heavily on the target resolution and desired frame rate. At 1080p, all presets are playable, with even Ultra achieving 77 FPS average. For users with high refresh rate monitors, the Low preset at 139 FPS or Medium at 108 FPS will provide the smoothest experience, though the visual quality trade-off may not be worth it for a simulation game where detail matters. The Medium preset at 108 FPS with a minimum of 92 FPS is the sweet spot for 1080p, offering a good balance of visuals and performance.

At 1440p, the Medium preset is the recommended choice, with 87 FPS average and a minimum of 74 FPS, ensuring smooth gameplay even in demanding scenes. The High preset at 65 FPS is also viable, but the 62 FPS average on Ultra is borderline for a flight simulator where frame pacing consistency matters. The data shows that the jump from Medium to High costs 22 FPS, which is a significant drop, while the jump from High to Ultra only costs 3 FPS, suggesting that High is the most efficient setting for visual quality per frame.

At 4K, the situation is more constrained. The Medium preset at 64 FPS average with a 55 FPS minimum is the only preset that stays above 60 FPS on average, making it the clear recommendation for 4K gaming. The Low preset at 82 FPS is also playable, but the visual fidelity loss is substantial. The High and Ultra presets at 48 and 46 FPS respectively are below 60 FPS and may result in noticeable stuttering during complex scenes. Users with FreeSync or G-Sync displays may tolerate these lower frame rates, but for the best experience, Medium is the way to go.

For users who prioritize visual quality over frame rate, the 1440p High preset offers a good compromise, while those with 4K displays should accept the Medium preset as the maximum playable setting. The data does not support pushing beyond Medium at 4K, as the performance gains from lowering settings are more significant than the visual improvements from raising them.
