Microsoft Flight Simulator

Microsoft Flight Simulator is one of the most demanding titles in the benchmark database, and this pairing of the AMD Ryzen 7 5800XT with the AMD Radeon RX 7900 XTX delivers a strong, predictable experience. The data shows a system that is heavily GPU-bound at higher resolutions but retains enough CPU headroom to push very high frame rates at 1080p. This is a balanced combination for a flight sim where smoothness in the cockpit view matters more than raw competitive speed.

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

The AMD Ryzen 7 5800XT is an 8-core, 16-thread processor based on the Zen 3 architecture, running on the AM4 socket. It has a base clock of 3.80 GHz and a boost clock of 4.80 GHz, with a 105 W TDP. For a flight simulator that often has to simulate complex physics, weather systems, and AI traffic simultaneously, the thread count is critical. The 16 threads allow the CPU to handle the simulation workload while leaving resources for background tasks like scenery streaming.

In this specific pairing, the CPU’s single-thread and multi-thread performance are both relevant. The benchmark data shows a strong single-thread score of 959 in 3dmark_single_thread and a cinebench_r23 multicore score of 23794. These numbers suggest the 5800XT has enough per-core strength to feed the high-end RX 7900 XTX in less demanding scenes, but the measured frame rates reveal that the GPU becomes the limiting factor quickly as resolution increases. The CPU’s 32 MB of L3 cache helps with the large datasets often used in flight simulators, and its PCIe Gen 4 support with 20 lanes ensures the GPU has a fast path to system memory.

The processor’s performance relative to its peers is solid. It sits in the 86th percentile of all CPUs tested, with an average benchmark score of 29774. When compared to its nearest rivals, it trades blows with the AMD Ryzen 7 6800HS (deltaPct -0.3) and the AMD Ryzen 7 7840H (deltaPct -0.3), while slightly outperforming the AMD Ryzen 7 PRO 5755GE (deltaPct 0.1) and the AMD Ryzen AI 7 PRO 360 (deltaPct 0.3). These are all mobile or low-power chips, which highlights that the 5800XT is a very capable desktop part in its class.

How This Combo Ranks — use comboRankInGame vs other tested combos

Looking at the entire database of tested CPU-GPU combinations for Microsoft Flight Simulator, this pairing of the Ryzen 7 5800XT and Radeon RX 7900 XTX ranks 219th out of 1795 combos. That places it in the top 12% of all systems tested, which is a strong result given the game’s notorious demand on hardware. This rank indicates that the combination is well above average for this specific title, outperforming the vast majority of systems in the database.

The rank is not surprising given the raw power of both components. The RX 7900 XTX sits in the 85th percentile of all GPUs tested, and the CPU is in the 86th percentile. When you pair two components that are both above the 85th percentile, the resulting system will naturally land in the upper echelon of results. However, the rank also reflects the game’s specific scaling patterns; it is not a simple linear combination of scores, but rather a measure of how well these parts work together in this particular simulation environment.

Resolution Scaling — how FPS drops from 1080p to 4K and what it says about the limiting component

The resolution scaling tells a clear story about where the bottleneck lies. At 1080p with Low settings, the system achieves 188.6 FPS. Moving to 1440p Low drops that to 155.2 FPS, a 17.7% reduction. At 4K Low, the frame rate falls to 110.1 FPS, which is another 29% drop from 1440p. This pattern is consistent with a GPU-bound scenario; the CPU has plenty of headroom at lower resolutions, but the GPU’s workload increases dramatically as pixel count grows.

The gap between settings at each resolution further confirms this. At 1080p, the difference between Low and Ultra is 82.2 FPS (188.6 to 106.4). At 1440p, that spread narrows to 70.1 FPS (155.2 to 85.1). At 4K, the spread is just 46.2 FPS (110.1 to 63.9). As resolution increases, the Ultra settings become less punishing relative to Low because the GPU is already saturated with pixel work. This is a textbook sign of a GPU-limited system at higher resolutions, while the CPU is only really stretched at 1080p with lower settings.

Measured FPS Breakdown — resolution by resolution, settings by settings, exact numbers

The measured frame rates provide a complete picture of what to expect from this combo. At 1920x1080, the results are excellent across the board. Low settings produce 188.6 FPS, Medium drops to 151 FPS, High comes in at 109.3 FPS, and Ultra maintains a very playable 106.4 FPS. Even at Ultra, the system stays well above the 60 FPS threshold, making 1080p a non-issue for this hardware.

Moving to 2560x1440, the performance remains strong but the scaling becomes more apparent. Low settings yield 155.2 FPS, Medium produces 117.6 FPS, High delivers 88.9 FPS, and Ultra drops to 85.1 FPS. The jump from High to Ultra is only 3.8 FPS, suggesting that the Ultra preset is mostly GPU-bound at this resolution and the extra visual fidelity comes at a relatively small frame rate cost.

At 3840x2160, the system starts to feel the pressure. Low settings still manage 110.1 FPS, Medium hits 88.8 FPS, High provides 68.1 FPS, and Ultra drops to 63.9 FPS. The 4K Ultra result is the only point where the system dips close to the 60 FPS mark, but it stays above it. This indicates that the RX 7900 XTX’s 24 GB of GDDR6 memory and 960.0 GB/s bandwidth are sufficient for 4K, but the raw compute power is the limiting factor at the highest settings.

FAQ

Q: Is this CPU-GPU combo suitable for 4K gaming in Microsoft Flight Simulator?

A: Yes, the measured data shows 4K Ultra produces 63.9 FPS, which is above the 60 FPS target. Lowering to High settings at 4K provides a more comfortable 68.1 FPS, giving a small performance buffer.

Q: How does the Ryzen 7 5800XT compare to other CPUs in its price range?

A: The 5800XT scores 29774 on average, placing it in the 86th percentile. It outperforms the AMD Ryzen 7 PRO 5755GE by 0.1% and the AMD Ryzen AI 7 PRO 360 by 0.3%, while being slightly behind the AMD Ryzen 7 6800HS and AMD Ryzen 7 7840H by 0.3% each.

Q: What is the biggest performance gap between settings at 1440p?

A: The largest gap is between Low (155.2 FPS) and Ultra (85.1 FPS), a difference of 70.1 FPS. The gap between High and Ultra is only 3.8 FPS, suggesting diminishing returns at the top end.

Q: Does the system maintain 60+ FPS at all tested settings?

A: Yes, the lowest recorded average is 63.9 FPS at 4K Ultra. All other resolution and settings combinations stay above 68 FPS, with many exceeding 100 FPS.

Q: Which component limits performance at 1080p Low?

A: At 1080p Low, the system hits 188.6 FPS, which is likely near the CPU’s maximum frame delivery capability in this simulation. The GPU has plenty of headroom, so the CPU becomes the primary limiter at this low resolution and settings level.

Q: How does the RX 7900 XTX compare to its nearest GPU rivals?

A: The RX 7900 XTX has an average benchmark score of 44019, placing it in the 85th percentile. It is 0.8% faster than the NVIDIA GeForce RTX 4090 Mobile, 1.6% faster than the NVIDIA Quadro M6000, and 2% faster than the NVIDIA GeForce RTX 4070 Ti, while being 0.4% slower than the AMD Radeon Pro 580.

Settings Recommendations

For the best balance of visual fidelity and frame rate, the High preset is the recommended starting point across all resolutions. At 1080p, High delivers 109.3 FPS, which is a 2.9 FPS improvement over Ultra while likely providing 99% of the visual quality. At 1440p, High produces 88.9 FPS, which is smooth and leaves headroom for weather effects or dense scenery. At 4K, High gives 68.1 FPS, which is the sweet spot for a flight sim where consistent frame pacing is more important than absolute maximum detail.

If you prioritize maximum visual quality and have a 4K display, Ultra is viable at 63.9 FPS, but the data shows only a 4.2 FPS difference between High and Ultra at 4K. That 4 FPS is likely not worth the extra load on the GPU, especially in a game where frame drops during complex scenes can be jarring. For competitive or fast-paced flying, the Medium preset at 1440p provides 117.6 FPS, which is a strong option if you want high refresh rates without sacrificing too much detail. The Low preset is only recommended if you are chasing maximum frame rates for benchmarking or have a very high refresh rate monitor, as it produces 188.6 FPS at 1080p but sacrifices most of the visual immersion that makes the sim engaging.
