Microsoft Flight Simulator

The AMD Ryzen 7 5800X3D and AMD Radeon RX 6600 pairing in Microsoft Flight Simulator delivers a playable, if not spectacular, experience, with performance heavily dictated by resolution and the game’s demanding workload. The data shows this is a combination that favors 1080p and 1440p gaming over 4K, where the GPU becomes the primary limiting factor.

CPU Role — cores, clocks, and how they relate to this game's results

The Ryzen 7 5800X3D is an 8-core, 16-thread processor based on the Zen 3 architecture, with a base clock of 3.40 GHz and a boost clock of 4.50 GHz. This is a CPU designed to handle heavy multi-threaded workloads, and its substantial 96 MB of shared L3 cache is particularly relevant for a simulation like Microsoft Flight Simulator, which streams large amounts of terrain and aircraft data. The processor’s cache hierarchy includes 64 KB of L1 per core and 512 KB of L2 per core, creating a deep memory pool that helps maintain smooth frame pacing when the sim is processing complex scenery.

In synthetic benchmarks, the CPU posts a Cinebench R23 multicore score of 14317 and a single-core score of 1452. The Geekbench results show a multicore score of 11765 and a single-core score of 2017. These figures place the CPU in the 80th percentile among all tested processors, indicating it is a strong performer. However, in this specific game, the CPU’s role is less about raw multi-threaded peak and more about maintaining consistent frame delivery. The 3D V-Cache technology, which is implied by the "X3D" naming and the large L3 cache, helps ensure that the flight simulator’s data-heavy threads have quick access to information, reducing stutter and bottlenecking the GPU less than a CPU with a smaller cache might.

Compared to its nearest rivals, the Ryzen 7 5800X3D’s average benchmark score of 27896 is effectively tied with the AMD Ryzen 7 6800U (27887) and the Intel Core i9-10900K (27872), with a delta of 0% and 0.1% respectively. It is also within 0.1% of the AMD Ryzen AI 5 PRO 340 (27932) and 0.3% ahead of the Intel Core i5-12600KF (27799). This shows that while the CPU is capable, the core architecture isn't dramatically outpacing these rivals in general compute tasks; its advantage lies in the specific cache-sensitive workload of this flight simulator.

How This Combo Ranks

Within the database of tested combinations for Microsoft Flight Simulator, this specific CPU and GPU pairing ranks 2870 out of 3714 total combos. This places it in the lower-middle portion of the pack, ranking in roughly the 23rd percentile of tested configurations. This ranking is a direct result of the GPU’s limitations at higher resolutions, as the CPU is more than capable of feeding it data.

The rank indicates that while this is a functional setup, it is far from the top tier of performance for this sim. Many other combinations will deliver higher average frame rates, particularly at 4K. The data suggests that the bottleneck shifts dramatically across resolutions; at 1080p, the CPU and GPU are more balanced, but at 4K, the RX 6600’s performance ceiling prevents the 5800X3D from stretching its legs fully. The combo’s rank is a holistic measure that pulls down the CPU’s strong relative performance due to the GPU’s mid-range standing in the 63rd percentile of all GPUs.

A: The RX 6600 has an average benchmark score of 19036 and sits in the 63rd percentile of all GPUs. This places it in the mid-range tier. It is not a high-end card, and its performance is directly reflected in the 4K frame rates, which are below 60 FPS.

Q: Does the CPU become a bottleneck at 1080p?

A: The data suggests it is less of a bottleneck at 1080p. With the Low preset at 1080p, the combo reaches 92 FPS, and at Medium, it hits 72 FPS. These higher frame rates indicate that the CPU is able to feed the GPU effectively at this resolution, allowing the graphics card to work to its potential.

Measured FPS Breakdown

The measured FPS data reveals a clear performance hierarchy across resolutions and settings.

At 1920x1080, the combo performs best. The Low preset averages 92 FPS, providing a very fluid experience. Moving to Medium, the average drops to 72 FPS, with a minimum of 61 FPS and a maximum of 82 FPS, ensuring a stable and playable session. The High preset averages 54 FPS, and the Ultra preset averages 51 FPS. This means at 1080p, the user can choose between high-refresh-rate play on Low or a more visually robust, yet still playable, experience on High or Ultra.

At 2560x1440, performance takes a noticeable hit. The Low preset averages 74 FPS, which is still smooth. The Medium preset averages 58 FPS, with a minimum of 49 FPS and a maximum of 66 FPS, which is acceptable for a flight sim. The High preset drops to 43 FPS, and the Ultra preset falls to 41 FPS. These lower averages indicate the GPU is now struggling to maintain high frame rates, making 1440p High or Ultra a less desirable choice for consistent smoothness.

At 3840x2160, the GPU is clearly the limiting factor. The Low preset averages 55 FPS, which is the only 4K setting that approaches a smooth experience. The Medium preset averages 43 FPS, with a minimum of 36 FPS and a maximum of 49 FPS. The High preset averages 32 FPS, and the Ultra preset averages 31 FPS. The data shows that 4K is only viable on the Low preset, and even then, it is not guaranteed to maintain 60 FPS.

GPU Role — VRAM, clocks, and how they relate to this game's results

The AMD Radeon RX 6600 is a mid-range GPU built on the RDNA 2.0 architecture, featuring 8 GB of GDDR6 memory on a 128-bit bus, providing a memory bandwidth of 224.0 GB/s. The GPU has a base clock of 1626 MHz and a boost clock of 2491 MHz, with a game clock of 2044 MHz. This hardware configuration is the primary reason for the performance drop at higher resolutions.

The 8 GB of VRAM is sufficient for 1080p and 1440p at the settings tested, but at 4K, the combination of high resolution and texture detail can strain the memory capacity. The GPU’s raw compute power, rated at 8.928 TFLOPS for FP32, is simply not enough to push the high pixel counts of 4K at high settings in a demanding sim. The data shows this clearly: the average FPS at 4K Ultra is 31, which is only slightly better than the 4K High result of 32 FPS, showing that the GPU is likely maxed out in both scenarios.

In terms of its own benchmark scores, the RX 6600 has an average score of 19036, placing it in the 63rd percentile. This is a mid-range standing, and the card is closely matched with rivals like the NVIDIA Quadro K6000 (19030), the NVIDIA GeForce RTX 4050 Mobile (19049), and the NVIDIA Tesla K20m (19089). The performance deltas are less than 0.4%, meaning the RX 6600 is a solid, but not exceptional, performer in this class. The GPU's role in this combo is to provide a baseline of graphical capability that is best utilized at lower resolutions.

Settings Recommendations

Based on the measured FPS data, the optimal experience with this hardware depends heavily on the user's target resolution and frame rate preference.

For 1080p gaming, the Medium preset offers the best balance. With an average of 72 FPS and a minimum of 61 FPS, it provides a smooth and stable experience that is well above the 30 FPS baseline for a simulator. This setting will offer a significantly better visual experience than Low (92 FPS) while maintaining playable frame rates. The Ultra preset (51 FPS) is also viable for those who prioritize visual fidelity over a high frame rate, but the Medium preset is the safest recommendation for consistent smoothness.

For 1440p gaming, the Medium preset is the recommended choice. It averages 58 FPS, with a minimum of 49 FPS, which is playable for a flight simulator. The Low preset (74 FPS) is also an option for a smoother experience, but the Medium preset provides a better visual balance without falling below 45 FPS. The High and Ultra presets, averaging 43 and 41 FPS respectively, are less recommended as they are more likely to feel less responsive.

For 4K gaming, the Low preset is the only realistic option, yielding an average of 55 FPS. The Medium preset (43 FPS) is borderline playable, but the High and Ultra presets (32 and 31 FPS) should be avoided for a smooth experience. The data suggests that users with 4K displays should either stick to the Low preset or consider reducing the resolution to 1440p for a better visual and performance trade-off.
