# Microsoft Flight Simulator: AMD Ryzen 7 5800XT + NVIDIA GeForce RTX 5090

This combo ranks 35th out of 1,795 tested combinations in Microsoft Flight Simulator, placing it in the top 2% of all systems benchmarked. The pairing of AMD's 5000-series desktop processor with NVIDIA's flagship GeForce 50-series GPU delivers exceptional performance, though the data reveals interesting scaling characteristics that highlight where each component's strengths lie. The RTX 5090's massive 32 GB frame buffer and the Ryzen 7 5800XT's eight Zen 3 cores combine to produce triple-digit frame rates across most settings, with only the most demanding 4K Ultra configuration dropping below 100 FPS.

How This Combo Ranks

The 35th position out of 1,795 combos represents a strong showing, placing this system ahead of approximately 98% of all tested configurations in Microsoft Flight Simulator. This ranking reflects the balanced nature of the pairing—the RTX 5090's raw compute power is complemented by the Ryzen 7 5800XT's solid multi-threaded performance. The CPU's average benchmark score of 29,774 places it in the 86th percentile among all processors, while the GPU's average score of 84,306 puts it in the 94th percentile among all graphics cards. This slight gap between CPU and GPU percentiles suggests the processor is the more limiting factor, though the practical impact remains minimal given the high overall ranking.

Interestingly, the RTX 5090's nearest rivals in the GPU benchmark database include the RTX 5090 D (0.1% higher average score), the RTX 5050 Mobile (0.2% higher), and the AMD Radeon PRO W6600 (1.3% higher), while the NVIDIA CMP 40HX trails by 1.6%. For the CPU, the Ryzen 7 5800XT sits within 0.3% of the AMD Ryzen 7 PRO 5755GE and Ryzen AI 7 PRO 360, and within 0.3% of the Ryzen 7 6800HS and Ryzen 7 7840H. These tight margins indicate that the 5800XT delivers performance consistent with its mid-range positioning, yet the combo still achieves top-35 status thanks to the GPU's dominance.

GPU Role

The NVIDIA GeForce RTX 5090 is the clear performance driver in this configuration, built on the Blackwell 2.0 architecture with 21,760 shading units, 680 texture mapping units, and 176 raster output units. Its 32 GB of GDDR7 memory on a 512-bit bus provides 1.79 TB/s of bandwidth, which proves critical for Microsoft Flight Simulator's vast, texture-heavy environments. The GPU's base clock of 2017 MHz and boost clock of 2407 MHz, combined with memory running at 1750 MHz (28 Gbps effective), enable the card to sustain high frame rates even when the simulator streams detailed terrain and aircraft models. The RTX 5090's 170 ray tracing cores and 680 tensor cores also contribute to the game's visual fidelity features, though the benchmark data focuses on rasterized performance.

The GPU's 104.8 TFLOPS of FP32 performance and 423.6 GPixel/s pixel rate explain why the combo excels at higher resolutions. At 4K Ultra, the card still manages 80.6 FPS, proof of its raw throughput. The 1,636.8 GTexel/s texture rate ensures that the game's dense scenery textures are processed without bottlenecking the frame pipeline. The GPU's 94th percentile ranking among all GPUs, with an average benchmark score of 84,306, confirms its position as a top-tier component. Notably, the RTX 5090's predecessor is the GeForce 40 series, and this Blackwell card represents a significant architectural leap with its 92,200 million transistors on a 5 nm TSMC process.

CPU Role

The AMD Ryzen 7 5800XT provides the computational foundation for this combo, featuring 8 cores and 16 threads based on the Zen 3 architecture (codenamed Vermeer). With a base clock of 3.80 GHz and boost clock of 4.80 GHz, this processor delivers strong single-threaded performance—critical for Microsoft Flight Simulator's simulation logic—while its 32 MB of L3 cache helps reduce memory latency during complex flight calculations. The CPU's 105 W TDP and dual-channel DDR4 memory support (51.2 GB/s bandwidth) are adequate for feeding the RTX 5090, though the PCIe Gen 4 interface with 20 lanes provides sufficient bandwidth for the GPU's data transfers.

Benchmark results show the 5800XT achieving a Cinebench R23 multi-core score of 23,794 and a single-core score of 3,359, with a PassMark multi-thread score of 27,988. The CPU's 86th percentile ranking among all processors and average benchmark score of 29,774 place it within 0.3% of several comparable AMD parts, including the Ryzen 7 PRO 5755GE and Ryzen 7 7840H. While the processor is not the absolute fastest available, its 3DMark scores—7,683 for 16 threads and 959 for single thread—demonstrate balanced performance that avoids creating a severe bottleneck. The CPU's launch MSRP of $249 reflects its mainstream positioning, but the data shows it pairs effectively with the flagship GPU.

Measured FPS Breakdown

At 1920x1080, the combo delivers its highest frame rates: 183.7 FPS on Low settings, 172.8 FPS on Medium, 142.3 FPS on High, and 133.9 FPS on Ultra. These numbers indicate that at 1080p, the CPU begins to limit performance—the gap between Low and Ultra is only 49.8 FPS, suggesting the GPU has ample headroom at this resolution. Moving to 2560x1440, the results remain strong: 175.5 FPS on Low, 152.4 FPS on Medium, 115.1 FPS on High, and 106.2 FPS on Ultra. The scaling from 1080p to 1440p shows a 8.2 FPS drop on Low settings but a 27.7 FPS drop on Ultra, indicating that higher settings shift more load onto the GPU.

At 3840x2160, the RTX 5090's capabilities become fully apparent: 139.2 FPS on Low, 109.6 FPS on Medium, 80.5 FPS on High, and 80.6 FPS on Ultra. The near-identical performance between High (80.5 FPS) and Ultra (80.6 FPS) at 4K suggests the game's Ultra preset may introduce settings that are not GPU-bound at this resolution, or that the CPU's simulation workload becomes the limiting factor. The 4K results show a 58.6 FPS difference between Low and Ultra settings, demonstrating that the GPU handles the increased resolution effectively but that the most demanding preset still pushes the system to its limits.

Resolution Scaling

The transition from 1080p to 4K reveals important insights about component utilization. At Low settings, the frame rate drops from 183.7 FPS at 1080p to 175.5 FPS at 1440p (a 4.5% decrease) and then to 139.2 FPS at 4K (a 20.7% decrease from 1440p). This pattern indicates that at Low settings, the CPU is the primary bottleneck at 1080p—the GPU can easily render the simpler scenes, but the processor's simulation calculations cap performance. As resolution increases, the GPU gradually becomes more engaged, yet the relatively modest 4K drop suggests the CPU still plays a significant role even at higher pixel counts.

At Ultra settings, the scaling is more pronounced: 133.9 FPS at 1080p drops to 106.2 FPS at 1440p (a 20.7% decrease) and then to 80.6 FPS at 4K (a 24.1% decrease from 1440p). This steeper decline at higher settings demonstrates that the GPU becomes the limiting component when visual fidelity increases, though the 4K Ultra result of 80.6 FPS remains highly playable. The High settings tell a similar story: 142.3 FPS at 1080p, 115.1 FPS at 1440p (19.1% decrease), and 80.5 FPS at 4K (30.1% decrease). The data suggests that for this game, the sweet spot is 1440p with High or Ultra settings, where the combo maintains above 100 FPS while delivering strong visual quality. At 4K, users may prefer Medium settings (109.6 FPS) over High or Ultra (both around 80 FPS) for smoother gameplay, as the visual difference may not justify the 29 FPS drop.
