Microsoft Flight Simulator

Microsoft Flight Simulator is notoriously demanding, and the measured data for the AMD Ryzen 7 5800X paired with the AMD Radeon RX 7600 XT confirms that this combination occupies a specific performance tier. The benchmark results show a system that can deliver playable frame rates at lower resolutions and settings, but which struggles to maintain smooth performance at 4K with high visual fidelity. This analysis breaks down the measured FPS data to understand the balance between the CPU and GPU, how the system scales with resolution, and what settings provide the best experience.

Resolution Scaling

The measured FPS data reveals a steep performance curve as resolution increases, clearly indicating that the graphics card becomes the primary limiting factor at higher pixel counts. At 1080p with Low settings, the system achieves an average of 104 FPS, but this drops to 83.9 FPS at 1440p and further to 61.7 FPS at 4K. This represents a 40.6% reduction in frame rate from 1080p to 4K at Low settings, which is a significant hit that points directly at the GPU struggling to fill the increased pixel count.

The scaling pattern becomes even more pronounced at higher settings. With High settings, the average FPS falls from 64.2 at 1080p to 47.1 at 1440p (a 26.6% drop), and then to 36.7 at 4K (a further 22.1% drop from 1440p). At Ultra settings, the numbers show 56.1 FPS at 1080p, 49.2 FPS at 1440p, and 31.5 FPS at 4K. The relatively smaller gap between 1080p and 1440p at Ultra settings, compared to the larger drop to 4K, suggests that the CPU is still contributing meaningfully at lower resolutions, but the GPU's workload becomes overwhelming at 4K.

The data indicates that the transition from 1440p to 4K is particularly brutal for this combination. At Medium settings, the frame rate drops from 67 FPS at 1440p to 44.8 FPS at 4K, a 33.1% reduction. This pattern across all settings suggests that the RX 7600 XT's 128-bit memory bus and 288.0 GB/s bandwidth are insufficient to sustain high frame rates at 4K, especially with the demanding scenery and terrain rendering of Microsoft Flight Simulator. The 8-core, 16-thread Ryzen 7 5800X with its 32 MB of L3 cache appears to keep up with the GPU at 1080p, but the rendering pipeline becomes GPU-bound as resolution rises.

GPU Role

The AMD Radeon RX 7600 XT is built on the RDNA 3.0 architecture with a Navi 33 chip, featuring 16 GB of GDDR6 memory on a 128-bit bus. The memory runs at 2250 MHz with 18 Gbps effective speed, providing a bandwidth of 288.0 GB/s. This memory configuration is a key factor in the 4K performance, as the large frame buffers required by flight simulation at high resolutions can strain the bandwidth. The GPU's boost clock of 2755 MHz and game clock of 2470 MHz are relatively high, but the 2048 shading units and 64 ROPs limit the raw fill rate.

The GPU benchmarks place it in the 63rd percentile among all GPUs, with an average benchmark score of 20146. Its nearest rival in the data is the AMD Radeon RX 7600, which scores 20258, a delta of -0.6% relative to the RX 7600 XT. This indicates that the two cards perform nearly identically in synthetic benchmarks, despite the XT variant having double the memory (16 GB vs 8 GB). The RX 7600 XT also sits 1.9% ahead of the NVIDIA GeForce RTX 2060 SUPER (score 19774) and 1.9% behind the NVIDIA GeForce RTX 3070 Mobile (score 20534).

In the context of Microsoft Flight Simulator, the 16 GB VRAM capacity is a significant asset, as the game can consume large amounts of memory for high-resolution textures and scenery data. However, the measured FPS at 4K Ultra (31.5 FPS) suggests that memory capacity is not the bottleneck; rather, it is the memory bandwidth and raw compute throughput. The GPU's FP32 performance of 22.57 TFLOPS is respectable, but the game's complex rendering pipeline, including dynamic lighting and shadow calculations, requires more than raw throughput at 4K. The data shows that the GPU is the limiting component at 4K, as evidenced by the dramatic FPS drops across all settings when moving from 1440p to 4K.

FAQ

Q: What is the maximum average FPS this combination can achieve in Microsoft Flight Simulator?

A: The highest measured average FPS is 104, which occurs at 1920x1080 resolution with Low settings. This drops to 83.9 FPS at 1440p Low and 61.7 FPS at 4K Low.

Q: How does the RX 7600 XT compare to its closest rival, the RX 7600?

A: The RX 7600 XT has an average benchmark score of 20146, while the RX 7600 scores 20258. This represents a delta of -0.6%, meaning the RX 7600 XT is actually slightly slower in average benchmarks, despite having 16 GB of VRAM compared to the RX 7600's 8 GB.

Q: Is the CPU or GPU the bottleneck at 1080p resolution?

A: The data suggests the CPU is still relevant at 1080p. At Low settings, the FPS drops from 104 at 1080p to 83.9 at 1440p, which is a 19.3% reduction. This relatively modest drop indicates that the CPU can still feed the GPU adequately at 1080p, but the GPU becomes more of a limiting factor as resolution increases.

Q: What is the largest FPS drop when moving from 1440p to 4K?

A: The largest percentage drop occurs at Medium settings, where the average FPS falls from 67 at 1440p to 44.8 at 4K, a 33.1% reduction. At High settings, the drop is 22.1% (47.1 to 36.7 FPS), and at Ultra it is 36.0% (49.2 to 31.5 FPS).

Q: How does this combo rank compared to other tested combinations?

A: This combination ranks 1152 out of 1795 tested combos in Microsoft Flight Simulator, placing it in the lower third of all configurations. This suggests that while it can run the game, many other CPU-GPU pairings deliver higher performance.

Q: What is the lowest measured FPS for this combo?

A: The lowest average FPS is 31.5, recorded at 3840x2160 resolution with Ultra settings. This is below the generally accepted 60 FPS threshold for smooth gameplay and indicates that 4K Ultra is not a viable configuration.

Settings Recommendations

The measured FPS data provides clear guidance on which settings preset offers the best balance of visual quality and performance. At 1080p, the Medium preset delivers 82.4 FPS, which is a substantial 28.3% improvement over High settings (64.2 FPS) while still offering better visuals than Low (104 FPS). The Ultra preset at 1080p yields 56.1 FPS, which is playable but not ideal for a flight simulator where smooth panning is important. The data suggests that 1080p Medium is the sweet spot, providing a comfortable frame rate headroom above 60 FPS.

For 1440p resolution, the Medium preset at 67 FPS is the only setting that maintains a playable frame rate above 60 FPS. The High preset at 47.1 FPS and Ultra at 49.2 FPS are very close, but both fall below the 60 FPS threshold. The Low preset at 83.9 FPS offers the smoothest experience, but it sacrifices significant visual detail. Given that the gap between High and Ultra at 1440p is only 2.1 FPS, there is little reason to choose High over Ultra if visual quality is the priority; the Ultra preset provides better visuals at nearly the same performance cost.

At 4K resolution, the data shows that only the Low preset (61.7 FPS) comes close to 60 FPS, while Medium (44.8 FPS), High (36.7 FPS), and Ultra (31.5 FPS) all fall well below. The recommendation is to avoid 4K unless the user is willing to accept Low settings, as the performance penalty for higher presets is severe. The overall best experience across all resolutions is the Medium preset at 1080p, which provides a balanced 82.4 FPS that leaves room for the complex scenery loading that occurs during flight.

How This Combo Ranks

In the database of tested combinations for Microsoft Flight Simulator, this pairing of the AMD Ryzen 7 5800X and the AMD Radeon RX 7600 XT ranks 1152 out of 1795 total combos. This places the system in the 64.2nd percentile of all tested configurations, meaning roughly 64% of other combinations perform better. The rank is a direct reflection of the measured FPS data, which shows strong 1080p performance but significant weaknesses at higher resolutions.

The CPU's benchmark scores help contextualize this rank. The Ryzen 7 5800X has an average benchmark score of 27606 and sits in the 84th percentile among all CPUs. Its nearest rival, the AMD Ryzen 7 5800, scores 27535, a delta of 0.3% in favor of the 5800X. The Intel Core i7-13700H scores 27716, which is 0.4% higher than the 5800X, while the Intel Core i5-12600KF scores 27827, 0.8% higher. These small deltas indicate that the CPU is well within the performance range of its immediate competitors.

The GPU, on the other hand, shows a more mixed picture. The RX 7600 XT's average benchmark score of 20146 places it in the 63rd percentile of all GPUs. Its nearest rival, the RX 460, scores 20088 (a 0.3% delta), which is a surprising comparison given the generational gap. The RX 7600 scores 20258 (-0.6% delta), and the RTX 2060 SUPER scores 19774 (1.9% delta). The fact that this modern GPU is only marginally faster than the RX 460 in average benchmarks, while being slower than the RX 7600, suggests that the card's performance is not exceptional in this dataset. The overall rank of 1152 reflects the GPU's mid-tier positioning rather than the CPU's strong showing.

Measured FPS Breakdown

The complete set of measured average FPS values provides a comprehensive view of the system's performance across resolutions and settings. At 1920x1080, the Low preset delivers 104 FPS, the Medium preset delivers 82.4 FPS, the High preset delivers 64.2 FPS, and the Ultra preset delivers 56.1 FPS. The progression from Low to Ultra shows a 46.1% decrease in frame rate, which is a substantial cost for the visual improvements.

At 2560x1440, the values are 83.9 FPS for Low, 67 FPS for Medium, 47.1 FPS for High, and 49.2 FPS for Ultra. The unusual inversion where Ultra (49.2 FPS) outperforms High (47.1 FPS) by 2.1 FPS is notable, though it could be attributed to measurement variance or specific scene loading. The overall trend from Low to Ultra shows a 41.3% decrease, similar to the 1080p pattern.

At 3840x2160, the Low preset achieves 61.7 FPS, Medium achieves 44.8 FPS, High achieves 36.7 FPS, and Ultra achieves 31.5 FPS. The drop from Low to Ultra is 49.0%, the largest percentage reduction across all resolutions. This reinforces the conclusion that the GPU is heavily taxed at 4K, with the highest settings producing an unplayable average FPS. The data across all resolutions shows a clear pattern: the system is capable at 1080p, usable at 1440p with Medium settings, and only viable at 4K with Low settings.
