Microsoft Flight Simulator

The AMD Ryzen 7 5800X and AMD Radeon RX 6600 XT pairing delivers a playable, if not always flawless, experience in Microsoft Flight Simulator. The data shows a configuration that is heavily influenced by the simulator’s notorious reliance on single-threaded CPU performance and raw GPU rasterization. This combo sits in the 70th percentile of all tested configurations, indicating a solid mid-to-upper tier standing, though the benchmark results reveal significant performance variance depending on resolution and graphical presets.

GPU Role

The AMD Radeon RX 6600 XT is a 7nm RDNA 2.0 part with 2048 shading units, 32 ray accelerators, and a boost clock of 2589 MHz. Its 8 GB of GDDR6 memory operates at 16 Gbps effective, delivering a bandwidth of 256.0 GB/s. The GPU's synthetic benchmarks show it has a Passmark G3D score of 16461, placing it in the 71st percentile of all GPUs. This positions it as a capable 1080p and entry-level 1440p card, which is reflected in the measured FPS data.

In Microsoft Flight Simulator, the GPU's role is most apparent at higher resolutions and settings. The data shows a clear scaling pattern. At 1920x1080 with Low settings, the combo achieves an average of 102.2 FPS, but this drops to 55.2 FPS at Ultra. The most significant bottleneck appears at 3840x2160. Here, even with Low settings, the average FPS is 60.2, but it plummets to 33.7 FPS at Ultra. This indicates that the 8 GB frame buffer and the 256.0 GB/s bandwidth are the limiting factors at 4K, where the simulator's texture streaming and draw calls overwhelm the GPU. The card's performance is close to the NVIDIA GeForce GTX 980 Ti (0.1% ahead) and 0.9% behind the RTX 3070, but the data suggests that in this specific game, the RX 6600 XT's architecture handles the load adequately until the resolution and settings push past its memory capacity.

CPU Role

The AMD Ryzen 7 5800X is a Zen 3 (Vermeer) processor with 8 cores and 16 threads. It has a base clock of 3.80 GHz and a boost clock of 4.70 GHz. For a flight simulator like Microsoft Flight Simulator, which is known for its heavy single-threaded simulation logic, the CPU's 3DMark single-thread score of 943 is a critical metric. This performance places it in the 84th percentile of all CPUs, with an average benchmark score of 27606.

The CPU's single-thread performance is its primary asset here. Its nearest rivals, the AMD Ryzen 7 5800 and Intel Core i5-12600KF, are within a 0.8% delta in average score, indicating that the 5800X is right at the top of its class for this workload. The 32 MB of L3 cache and the Zen 3 architecture help maintain high instruction throughput, which is essential for the simulation's complex flight models. While multicore performance (Cinebench R23 score of 23571) is more than sufficient for the OS and background tasks, the single-thread prowess is what allows the combo to maintain playable frame rates at lower resolutions where the CPU is the primary bottleneck. The data shows that at 1080p Low, the system hits 102.2 FPS, but at 1080p Ultra, it drops to 55.2 FPS, suggesting the CPU is still feeding the GPU enough data to keep the frame rate from collapsing entirely, even under high graphical load.

How This Combo Ranks

In the grand scheme of all tested configurations for Microsoft Flight Simulator, this Ryzen 7 5800X + RX 6600 XT combo ranks 1256 out of 1795, which is in the 70th percentile. This is a respectable position, but it is not a top-tier setup. The ranking indicates that while the components are individually strong, the pairing does not push into the upper echelon of performance. This is likely due to the RX 6600 XT's 8 GB VRAM and 128-bit memory bus, which limit its performance in the most demanding scenarios.

The CPU's position is strong; its average benchmark score of 27606 is only 0.3% behind the AMD Ryzen 7 5800 and 0.4% ahead of the AMD Ryzen 5 8500GE. The GPU, however, is less dominant. Its average score of 27985 is 0.9% behind the NVIDIA GeForce RTX 3070. When combined, the system's strengths and weaknesses are somewhat neutralized. The data suggests that the combo is well-balanced for 1080p and capable at 1440p, but the GPU becomes the clear limiting factor at 4K, preventing the combo from climbing higher in the rankings.

Measured FPS Breakdown

The measured FPS data provides a clear picture of performance scaling across resolutions and settings. The system was tested at three resolutions (1920x1080, 2560x1440, and 3840x2160) with four settings levels (Low, Medium, High, Ultra).

At 1920x1080, the combo performs admirably. Low settings yield an average of 102.2 FPS, Medium drops to 76.0 FPS, and High produces 57.4 FPS. Ultra settings bring the average down to 55.2 FPS. This demonstrates that the system is fully capable of high-refresh-rate play at lower settings and remains smooth above 55 FPS even at Ultra.

Moving to 2560x1440, the demand on the GPU increases. Low settings still deliver a high average of 81.4 FPS. Medium settings drop to 62.6 FPS. High and Ultra settings yield nearly identical results, with averages of 47.3 FPS and 47.2 FPS, respectively. This suggests that at 1440p, the GPU is becoming the primary bottleneck, as the difference between High and Ultra is minimal. The system remains playable, but the 47 FPS average at Ultra is close to the edge of what many consider a smooth experience for a flight sim.

At 3840x2160, the system struggles to maintain high frame rates. Low settings produce an average of 60.2 FPS, which is playable. Medium settings drop to 45.0 FPS, and High settings fall to 36.4 FPS. Ultra settings bottom out at 33.7 FPS. These numbers indicate that the 8 GB VRAM and 256.0 GB/s bandwidth are insufficient for 4K Ultra textures and draw distances. While the system is technically playable at 4K with Low settings, the frame rates at High and Ultra are on the edge of playability, making 1440p the realistic sweet spot for this combination.
