Microsoft Flight Simulator

The AMD Ryzen 7 5800X paired with the AMD Radeon RX 5700 XT delivers a playable but resolution-sensitive experience in Microsoft Flight Simulator. The benchmark data shows a system where the GPU becomes the dominant limiter as resolution climbs, while the CPU’s eight-core architecture provides enough headroom to keep frame rates consistent at lower settings. This analysis draws exclusively on measured FPS rows, component specifications, and comparative ranking data.

Resolution Scaling

The measured FPS data reveals a clear and predictable pattern: as resolution increases from 1920x1080 to 3840x2160, average frame rates drop substantially across all four settings presets. The scaling is nearly linear in some cases, but the GPU’s workload becomes increasingly heavy at higher pixel counts, making the RX 5700 XT the primary constraint.

At 1920x1080, the RX 5700 XT delivers its highest measured averages. Low settings produce 98 FPS, Medium produces 77 FPS, High produces 58 FPS, and Ultra produces 55 FPS. This is the only resolution where any preset exceeds the 90 FPS mark, and it shows that the CPU is not limiting the frame rate here. Moving to 2560x1440, the average FPS drops by roughly 19-20% across all presets. Low goes from 98 to 79, Medium from 77 to 62, High from 58 to 46, and Ultra from 55 to 44. The drop from 1080p to 1440p is moderately steep, indicating that the GPU is already starting to strain under the added pixel workload.

At 3840x2160, the RX 5700 XT is clearly overwhelmed. Low preset average FPS falls to 59, Medium to 46, High to 34, and Ultra to 33. The gap between 1440p and 4K is dramatic for Low and High. Low drops from 79 to 59 (a 25% reduction), while High drops from 46 to 34 (a 26% reduction). The Medium preset shows the most representative scaling, with 62 FPS at 1440p dropping to 46 FPS at 4K, a 26% loss. Ultra is the only preset that barely changes, going from 55 at 1080p to 44 at 1440p to 33 at 4K, but this is because Ultra is already GPU-limited at every resolution.

The data suggests that the RX 5700 XT is the limiting component at 4K, regardless of settings. Even at Low, the 4K average of 59 is barely above the 1440p High average of 46, meaning the GPU cannot sustain high frame rates at this resolution. The steepest scaling occurs between 1440p and 4K, where the pixel count doubles from 3.7 million to 8.3 million, and the GPU’s 448 GB/s memory bandwidth and 9.754 TFLOPS of FP32 compute are insufficient to handle the geometry and texture loads of Microsoft Flight Simulator at 4K.

The CPU is not the bottleneck at any resolution. The Ryzen 7 5800X’s eight cores with SMT provide enough thread-level parallelism for the flight sim’s simulation and rendering tasks. The data shows that when settings are lowered, the FPS increases in a way that is consistent with GPU scaling, not CPU scaling. For example, at 1080p, the difference between Low and Ultra is 98 vs 55 FPS, which is a 78% increase from Low to Ultra. This is a GPU-driven gap, not a CPU-driven one. The CPU’s single-thread performance, as seen in Cinebench R23 single-core scoring 1574.5, is more than enough for the game’s main thread.

CPU Role

The AMD Ryzen 7 5800X is an eight-core, sixteen-thread processor based on the Zen 3 architecture, code-named Vermeer, built on TSMC’s 7 nm process node. It has a base clock of 3.80 GHz and a boost clock of 4.70 GHz. The processor has 32 MB of L3 cache, 512 KB of L2 per core, and 64 KB of L1 per core. It supports DDR4 memory with dual-channel access and a theoretical memory bandwidth of 51.2 GB/s. This platform, with its PCIe Gen 4 interface offering 20 lanes, is well-suited for modern GPUs.

In Microsoft Flight Simulator, the CPU is responsible for the game’s simulation loop, physics, and scenery generation. The benchmark results indicate that the CPU is not limiting the frame rate at any tested resolution. The 3DMark single-thread score of 943 and passmark single-thread score of 3445 show strong per-core performance. The 3DMark 8-thread score of 6035 and max-thread score of 7578 demonstrate that the processor scales well with more threads, which is useful for a game that can utilize multiple cores for background tasks like terrain streaming and AI traffic.

The CPU’s 81st percentile ranking among all CPUs confirms that it sits above the vast majority of desktop processors. Its average benchmark score of 29123 is nearly identical to its closest rivals, with a delta of only 0.1% to the Intel Core Ultra 5 135H and -0.5% to the Intel Core i5-13500HX. This tells us the 5800X’s raw compute is in the same league as modern mid-range mobile chips, which is a positive sign for a processor released in 2020.

The Ryzen 7 5800X’s 8-core/16-thread configuration is more than adequate for this flight. The game does not require massive core counts, but the processor’s high single-core boost of 4.70 GHz helps maintain low latency for the game’s main thread. The CPU’s 32 MB of L3 cache reduces memory access time, which is important for the game’s loading and streaming behaviors. The measured FPS data shows that even at 1080p Low, the CPU can push 98 fps without bottleneck, and the frame rate scales down with GPU load rather than CPU load.

A key observation from the data is the effect of settings on CPU load. At 4K Ultra, the average FPS is 33, which is lower than the 4K Low average of 59. This is a GPU limitation, not a CPU limitation. The CPU’s ability to feed the GPU is not the issue. The GPU’s texture rate of 304.8 GTexel/s and pixel rate of 121.9 GPixel/s are the limiting factors. The CPU’s memory bandwidth of 51.2 GB/s is also not a bottleneck in this case, as the game’s data does not require more than that.

The Ryzen 7 5800X’s 3DMark max-thread score of 7578 is nearly identical to its 16-thread score of 7586, indicating that the processor is fully saturated with 16 threads. This suggests that the game might benefit from more cores, but the performance would not double. In this game, the CPU is not the limiting factor at any resolution or setting, as the FPS scaling is entirely driven by GPU load.

Settings Recommendations

The measured FPS rows provide clear guidance for what settings to use at each resolution. At 1920x1080, all presets are playable, but the best experience depends on the user’s preference. Low averages 98 FPS, which is ideal for high-refresh-rate monitors. Medium averages 77 FPS, High averages 58 FPS, and Ultra averages 55 FPS. For a balanced experience, Medium is the recommendation, as it offers a 77 FPS average with a 65 FPS minimum and 88 FPS maximum. This preset keeps the frame rate above 60 FPS most of the time while providing better visual quality than Low. High and Ultra are still playable but dip below 60 FPS, which may be noticeable in a simulation that requires smooth camera movement.

At 2560x1440, the options are more limited. Low averages 79 FPS, Medium averages 62 FPS with a 52 FPS minimum and 71 FPS maximum. High and Ultra fall to 46 and 44 FPS, respectively. The data shows that Medium is the best choice for 1440p. It maintains an average close to 60 FPS, and the measured minimum of 52 FPS is not a severe drop. High and Ultra are not recommended at this resolution unless the user is willing to accept lower frame rates.

At 3840x2160, the RX 5700 XT struggles. Low averages 46 FPS, Medium averages 46 FPS, High averages 34 FPS, and Ultra averages 33 FPS. None of these are ideal for a smooth experience. The best option is Low, which offers 57 FPS but still dips below 60. Medium is the second-best, with 46 FPS and a 39 FPS minimum. High and Ultra are not recommended at 4K because they drop below 35 FPS, which is too low for a flight simulator.

The Ultra preset is not the best choice at any resolution. At 1080p, it averages 55 FPS, which is only 3 FPS lower than High, but the visual difference may not justify the performance cost. At 1440p, Ultra drops to 44 FPS, and at 4K, it drops to 33 FPS. The data indicates that Ultra is a heavy preset that the RX 5700 XT cannot handle at higher resolutions.

For the best overall experience, prioritize resolution over settings. At 1080p, High is the sweet spot. At 1440p, Medium is the only preset that stays near 60 FPS. At 4K, the GPU is not capable of 60 FPS even on Low, so users should be prepared for a lower frame rate if they insist on 4K.

How This Combo Ranks

The combo of the AMD Ryzen 7 5800X and the AMD Radeon RX 5700 XT ranks 2745 out of 3714 tested combinations in Microsoft Flight Simulator. This places it in the 74th percentile of all tested combos. This is a mid-to-low ranking, which is consistent with the GPU’s position in the hardware hierarchy. The RX 5700 XT has a percentile of 59 among all GPUs, while the CPU has a percentile of 81 among all CPUs. The GPU is the weaker component in this pairing, and its performance in this game reflects that.

The combo rank is not surprising given the GPU’s average benchmark score of 16361, which is near its nearest rivals. The AMD Radeon Pro 5600M scores 16351 (delta 0.1%), the NVIDIA RTX PRO 6000 Blackwell scores 16408 (delta -0.3%), and the AMD Radeon PRO W7500 scores 16415 (delta -0.3%). These are all professional or high-end cards, but their scores are essentially identical to the RX 5700 XT. This means the RX 5700 XT’s raw compute is on par with much more modern cards, yet its lack of advanced features like hardware ray tracing limits its potential in some games, though not in Microsoft Flight Simulator’s.

The CPU’s ranking is better, but the combo rank is dragged down by the GPU. The Ryzen 7 5800X’s performance is in the 81st percentile, and its average benchmark score of 29123 is within 0.6% of the AMD Ryzen 5 5600XT and 0.1% of the Intel Core Ultra 5 135H. This shows that the CPU is not a weak link in this combo. The limitation is purely the GPU.

In the context of Microsoft Flight Simulator, the combo’s rank of 2745 out of 3714 is logical. The game is extremely demanding on the GPU due to its high-resolution textures and complex geometry. The RX 5700 XT with its 8 GB of GDDR6 memory and 448 GB/s bandwidth is enough for 1080p and medium settings at 1440p, but it lacks the raw compute to handle 4K. The CPU, on the other hand, provides enough single-thread performance and multi-thread capability to keep the game running smoothly. The rank reflects the GPU’s mid-range standing in the current market.

Measured FPS Breakdown

The measured FPS data provides a complete picture of the combo’s performance across three resolutions and four settings presets. At 1920x1080, the RX 5700 XT achieves its best results. For Low settings, the average FPS is 98. Medium settings produce an average of 77 FPS, with a minimum of 65 FPS and a maximum of 88 FPS. High settings yield an average of 58 FPS, and Ultra settings yield an average of 55 FPS. The difference between Medium and High is 19 FPS, which is significant. High drops below 60 FPS, while Medium stays above it.

At 2560x1440, the frame rates drop. Low settings average 79 FPS, which is still above 60. Medium settings average 62 FPS, with a minimum of 52 FPS and a maximum of 71 FPS. This is the only other preset that stays near 60. High settings average 46 FPS, and Ultra settings average 44 FPS. The gap between Low and High at 1440p is 33 FPS, which is larger than at 1080p. This indicates that the GPU is starting to become more of a limiting factor as resolution increases.

At 3840x2160, the RX 5700 XT’s limits are exposed. Low settings average 59 FPS, which is barely below the 60 FPS target. Medium settings average 46 FPS, with a minimum of 39 FPS and a maximum of 52 FPS. High settings average 34 FPS, and Ultra settings average 33 FPS. The 4K Medium result shows a minimum of 39 FPS, which indicates that the GPU can have significant frame drops even at the Medium preset. The data shows that 4K is not a viable resolution for this combo beyond Low.

The FPS breakdown also shows the scaling efficiency of the GPU. From 1080p to 1440p, the average FPS across all presets drops by about 19%. From 1440p to 4K, the drop in average FPS varies by preset. Low drops from 79 to 59 (a 25% reduction), Medium from 62 to 46 (a 26% reduction), High from 46 to 34 (a 26% reduction), and Ultra from 44 to 33 (a 25% reduction). This consistency indicates that the GPU is the bottleneck in all cases, and the CPU is not introducing any additional frame rate limiting.

The measured data confirms that the combo is best suited for 1080p and 1440p gaming. At 1080p, all presets are playable, with Low and Medium exceeding 60 FPS. At 1440p, only Low and Medium exceed 60 FPS. At 4K, no preset reaches 60 FPS, and the best option is Low with a 59 FPS average. This is the definitive performance profile for this combination.
