How This Combo Ranks

The combo's rank of 3538 out of 3714 tested combinations places it in the 5th percentile of all tested systems in Microsoft Flight Simulator. This is a very low ranking, suggesting that this specific pairing is far from optimal for this title. The data suggests a significant bottleneck exists, as the CPU's high performance is not being utilized by the GPU. The CPU itself ranks in the 80th percentile of all CPUs, while the GPU ranks in the 74th percentile of all GPUs. However, the combination of a top-tier CPU with a low-end GPU results in a system that performs far worse than the sum of its parts would suggest.

The benchmark results indicate that the RX 570 is the limiting factor in almost every scenario. While the Ryzen 7 5800X3D has the processing power to handle the complex simulation calculations, the GPU cannot keep up with the rendering demands, especially at higher resolutions. This is a classic case where the CPU has significant headroom, but the GPU is saturated, preventing the system from achieving higher frame rates. In practical terms, this combo is ranked among the lowest-performing systems in the database for this game, making it a poor choice for a smooth experience.

GPU Role

The AMD Radeon RX 570 is a 14 nm GPU based on the Polaris 20 chip and GCN 4.0 architecture. It has 2048 shading units, 128 TMUs, and 32 ROPs. Its memory configuration consists of 4 GB of GDDR5 on a 256-bit bus, providing a bandwidth of 224.0 GB/s. The GPU operates at a base clock of 1168 MHz and a boost clock of 1244 MHz.

In Microsoft Flight Simulator, the GPU's role is to render the highly detailed scenery, aircraft, and weather effects. The data shows that this GPU is simply not powerful enough for high-fidelity rendering at higher resolutions. At 3840x2160, the average FPS is 29 on Low, 22 on Medium, 17 on High, and 16 on Ultra. These numbers are consistently low, indicating the GPU is the primary bottleneck. The 4 GB VRAM is also a concern, as the game's high-resolution textures can easily exceed this limit, potentially causing stuttering or texture pop-in.

The GPU's performance relative to its rivals is interesting. Its average benchmark score is within 0.4% of the AMD Radeon RX 6800M and within 0.8% of the AMD Radeon RX 470. This indicates that in synthetic benchmarks, the RX 570 is on par with these other cards. However, in this game, the performance is dictated by the same hardware limitations. The GPU's 5.095 TFLOPS of FP32 performance is a modest figure that is insufficient for the demands of this simulation at high settings and resolutions.

Measured FPS Breakdown

The measured FPS data provides a clear picture of the system's capabilities across different settings and resolutions.

At 1920x1080, the best-case scenario is the Low preset, which yields an average of 48 FPS. The Medium preset averages 38 FPS, with a minimum of 32 and a maximum of 43 FPS. The High preset averages 28 FPS, and the Ultra preset averages 27 FPS. This resolution is the only one where the combo approaches playable frame rates, but only on the Low preset.

At 2560x1440, performance drops significantly. The Low preset averages 39 FPS. The Medium preset averages 30 FPS, with a minimum of 26 and a maximum of 35 FPS. The High preset averages 23 FPS, and the Ultra preset averages 22 FPS. The jump from 1080p to 1440p results in a roughly 20% performance drop on the Low preset and a 24% drop on the Medium preset.

At 3840x2160, the system struggles to maintain playable frame rates. The Low preset averages 29 FPS. The Medium preset averages 22 FPS, with a minimum of 19 and a maximum of 26 FPS. The High preset averages 17 FPS, and the Ultra preset averages 16 FPS. This resolution is not viable for this combo, as even the Low preset fails to hit a consistent 30 FPS average.

The data shows a clear trend: as resolution increases, the average FPS drops consistently. The difference between 1080p and 4K is substantial, with the Low preset dropping from 48 FPS to 29 FPS, a 40% reduction. This reinforces the conclusion that the RX 570 is the limiting factor, as the CPU's performance is resolution-independent while the GPU's workload scales with pixel count.

CPU Role

The AMD Ryzen 7 5800X3D is a desktop processor from the 5000 series, based on the Zen 3 architecture (codenamed Vermeer). It has 8 cores and 16 threads, with a base clock of 3.40 GHz and a boost clock of 4.50 GHz. It features a substantial 96 MB of shared L3 cache, which is a key characteristic of this specific processor. The CPU has a TDP of 105 W and uses the AMD Socket AM4.

In Microsoft Flight Simulator, the CPU is responsible for simulating flight physics, handling AI traffic, and managing the game's complex world data. The benchmark data for this CPU is strong, showing it in the 80th percentile of all CPUs. Its Cinebench R23 multi-core score is 14317, and its single-core score is 1452. Its 3DMark 16-thread score is 7299. Compared to its nearest rivals, it performs within 0.1% of the Intel Core i9-10900K and within 0.3% of the Intel Core i5-12600KF.

Given these strong CPU scores, the CPU is unlikely to be a significant bottleneck in this pairing. The high L3 cache and strong multi-threaded performance are well-suited for a simulation title. However, the measured FPS data shows that the system's performance is still very low, which strongly suggests that the GPU is the limiting factor. The CPU has ample headroom to push a more powerful GPU, but it is held back by the RX 570's inability to render frames quickly enough.

Settings Recommendations

Based on the measured FPS data, the optimal experience for this combo is found at 1920x1080 with the Low preset. This is the only configuration that achieves an average frame rate above 40 FPS, hitting 48 FPS. This is the only setting that provides a smooth and responsive experience, which is critical for a flight simulator where precise control is needed.

If a user prefers higher visual quality, the Medium preset at 1920x1080 is the next best option, averaging 38 FPS. While this is lower than the Low preset, it may still be acceptable for some users, especially in less demanding scenarios like cruising at altitude. The High and Ultra presets at 1080p should be avoided, as they both average below 30 FPS, which is generally considered the minimum for playable performance.

At higher resolutions, the data shows that the system is not capable of delivering a good experience. The 2560x1440 Low preset averages 39 FPS, which is borderline, but the Medium preset drops to 30 FPS. All settings at 3840x2160 are essentially unplayable, with averages ranging from 16 to 29 FPS. For this reason, it is recommended to stick to 1080p to get the best performance. The data clearly indicates that the Low preset at 1080p provides the best balance of playability and visual quality for this hardware combination.
