Microsoft Flight Simulator

Microsoft Flight Simulator with the AMD Ryzen 5 7600 and AMD Radeon RX 6800 XT presents a compelling balance between CPU and GPU capabilities for a demanding flight simulation. The measured data indicates a system that is capable of high frame rates at mainstream resolutions but begins to show its limits when pushed to maximum graphical presets at 4K. Overall, this combination ranks in the 69th percentile of all tested combos in this game, demonstrating strong, though not top-tier, performance for this specific title.

Resolution Scaling

The performance scaling from 1080p to 4K clearly illustrates the transition from a CPU-bound scenario to a GPU-bound one. At the "Low" preset, the average frame rate drops from 153 FPS at 1920x1080 to 123 FPS at 2560x1440, a 20% reduction, and then further to 91 FPS at 3840x2160, a 26% reduction from 1440p. This steep decline at 4K with low settings suggests that while the GPU is becoming the primary limiter, the Ryzen 5 7600's strong single-thread performance is still able to feed the graphics card adequately at the higher resolutions.

The scaling pattern shifts with more demanding settings. At "High" settings, the average FPS is 90 at 1080p, 72 at 1440p, and 53 at 4K. The drop from 1080p to 1440p is 20%, while the drop from 1440p to 4K is 26%. For the "Ultra" preset, the numbers are 85 FPS at 1080p, 69 FPS at 1440p, and 51 FPS at 4K. The consistent 20% and 26% reductions across these presets indicate that the rendering load is scaling predictably with resolution, and the system is hitting a performance ceiling that is heavily influenced by the GPU's fillrate and memory bandwidth once the resolution increases.

The most significant observation is the performance gap between the "Low" and "Ultra" presets at each resolution. At 1080p, the difference is 68 FPS (153 vs 85), but at 4K, this gap narrows to 40 FPS (91 vs 51). This convergence suggests that at 4K, the pixel throughput demands of even the "Low" preset are so high that the GPU cannot fully stretch its legs, making the absolute frame rate more dependent on the GPU's raw compute power than on the CPU's ability to prepare frames. The data shows the CPU is not the bottleneck at 4K, even on the "Low" preset, as the frame rate drop is substantial when moving from 1440p to 4K.

How This Combo Ranks

In the grand scheme of tested hardware combinations for Microsoft Flight Simulator, this pairing of the Ryzen 5 7600 and RX 6800 XT achieves a rank of 1156 out of 3714 combos. This places it in the upper third of all systems tested, indicating a solid performance level that should satisfy most users. The rank is a holistic measure that takes into account all tested resolutions and settings, showing that this system is well above the median performer for this specific title.

The CPU's individual standing in the broader market reinforces this. The Ryzen 5 7600 sits at the 78th percentile among all CPUs, which is a strong result. Its nearest rivals, such as the AMD Ryzen 9 6900HX and the Intel Core i9-11900KF, have average benchmark scores within 0.5% of the 7600, indicating that its processing power is very competitive with those parts. This high CPU percentile helps ensure that the combo does not fall behind due to processor limitations.

When considering the GPU's contribution, the RX 6800 XT is at the 85th percentile among all GPUs. This is a very high standing, but its nearest rivals include the NVIDIA GeForce RTX 5070 Ti, which is 3% faster in average benchmark scores. This suggests that while the GPU is a strong performer, there are faster options available that could push this combo higher in the rankings. The combination of a high-percentile CPU and a very high-percentile GPU results in the overall rank of 1156, demonstrating that the system's performance is well-balanced, with neither component holding the other back to a significant degree.

GPU Role

The AMD Radeon RX 6800 XT is a formidable component for this simulation, featuring 16 GB of GDDR6 memory on a 256-bit bus, providing a substantial 512.0 GB/s of memory bandwidth. This large memory pool is particularly advantageous for Microsoft Flight Simulator, which is known for loading vast amounts of high-resolution terrain and aircraft data. The benchmark results show that the GPU can handle the game's demands effectively, though its performance is influenced by clock speeds and rendering load.

With a boost clock of 2250 MHz and a game clock of 2015 MHz, the GPU demonstrates strong raw compute capability, rated at 20.74 TFLOPS for FP32 operations. This power is evident in the frame rates achieved. At the "Medium" preset, the GPU maintains a minimum FPS above 60 at both 1440p and 4K, with averages of 96 FPS and 71 FPS respectively. This suggests that the GPU has enough headroom to keep the experience smooth even when the visual complexity increases.

However, the data also shows the GPU's limits. At the "Ultra" preset, the average frame rate drops to 51 FPS at 4K and 69 FPS at 1440p. This indicates that the most demanding settings place a significant load on the GPU's shaders and memory system. The fact that the "Ultra" preset at 1080p (85 FPS) is not dramatically faster than the "High" preset at 1440p (72 FPS) suggests that the GPU is scaling well with resolution but is ultimately constrained by its pixel throughput and texture fillrate when all effects are enabled. The 16 GB VRAM is not a limiting factor in these results; rather, the GPU's compute and memory bandwidth are the primary determinants of performance at higher settings.

Settings Recommendations

Based on the measured frame rates, the "High" preset offers the best balance of visual fidelity and performance across all resolutions. At 1920x1080, it delivers a very smooth 90 FPS average, which is ideal for a flight simulator where smooth camera panning is crucial. At 2560x1440, the average drops to 72 FPS, which is still perfectly playable and provides a significant visual upgrade over 1080p. Even at 3840x2160, the "High" preset maintains a playable 53 FPS average, demonstrating that this setting is the sweet spot for this hardware combination.

For users with high-refresh-rate 1080p monitors, the "Low" preset provides an excellent experience with an average of 153 FPS, but it does so by sacrificing much of the visual detail that makes the simulator immersive. The "Medium" preset is a viable alternative for 1440p, offering a 96 FPS average with a minimum of 82 FPS, ensuring a consistent and stutter-free experience. However, the jump from "Medium" to "High" at 1440p is a 25% reduction in FPS (96 to 72), which may not be worth the visual gains for all users.

The "Ultra" preset is the most demanding, and the data suggests it is only suitable for 1080p displays, where it achieves an 85 FPS average. At 1440p and 4K, the "Ultra" preset pushes the system to its limits, with average frame rates of 69 FPS and 51 FPS respectively. For 4K gaming, the "High" preset is the clear recommendation, as it provides a 53 FPS average, which is a more stable and enjoyable experience than the 51 FPS average of the "Ultra" preset, likely with a higher minimum frame rate. Users seeking the best visual quality on a 4K display should consider that the "Ultra" preset's performance may dip too low for consistent smoothness.

Measured FPS Breakdown

The measured data provides a complete picture of performance across resolutions and presets. At 1920x1080, the system delivers an average of 153 FPS on "Low", 119 FPS on "Medium" (with a minimum of 101 FPS and maximum of 137 FPS), 90 FPS on "High", and 85 FPS on "Ultra". The 1080p results show a clear hierarchy, with the "Low" preset offering the highest frame rates and the "Ultra" preset providing the lowest, but all presets are highly playable at this resolution.

Moving to 2560x1440, the average frame rates are 123 FPS on "Low", 96 FPS on "Medium" (with a minimum of 82 FPS and maximum of 110 FPS), 72 FPS on "High", and 69 FPS on "Ultra". The 1440p results show a significant drop from 1080p, particularly on the "Low" preset, but the "Medium" and "High" presets still offer very good performance. The "Ultra" preset begins to approach the lower limit of what is considered smooth, but it remains playable.

At 3840x2160, the system produces averages of 91 FPS on "Low", 71 FPS on "Medium" (with a minimum of 60 FPS and maximum of 81 FPS), 53 FPS on "High", and 51 FPS on "Ultra". The 4K results are the most demanding, and while the "Low" and "Medium" presets are very smooth, the "High" and "Ultra" presets fall below the 60 FPS threshold. This indicates that for a locked 60 FPS experience at 4K, users must rely on the "Medium" preset or lower. The minimum FPS data at "Medium" (60 at 4K) suggests that this preset is the highest setting that can maintain a consistent 60 FPS floor.

CPU Role

The AMD Ryzen 5 7600, a 6-core, 12-thread processor based on the Zen 4 architecture, plays a crucial role in this system's performance. With a base clock of 3.80 GHz and a boost clock of 5.10 GHz, it provides excellent single-thread performance, which is critical for Microsoft Flight Simulator's main simulation thread. The benchmark data shows a strong single-thread score of 999 in 3DMark and 1852 in Cinebench R23, indicating its capability to handle the game's primary logic.

The CPU's 32 MB of shared L3 cache is also beneficial for this title, as it helps reduce memory latency when accessing frequently used game data. While the CPU has a significant impact on the game's ability to prepare frames, the measured results at low settings and high resolutions indicate that it is not the primary bottleneck at 4K. The frame rate drops from 1440p to 4K are substantial across all presets, confirming that the GPU is the limiting factor at those resolutions.

However, at 1080p with the "Low" preset, the system achieves 153 FPS, which is a very high frame rate. This indicates that the Ryzen 5 7600 has sufficient headroom to support high FPS gaming, even with a powerful GPU like the RX 6800 XT. The CPU's performance is consistent with its 78th percentile ranking among all CPUs, and its nearest rivals, including the AMD Ryzen 7 7435HS and the Intel Core i9-11900KF, show that it is a well-rounded processor. For this flight simulator, the CPU provides a solid foundation that does not impede the GPU's performance until the resolution and settings are pushed to their limits.
