Microsoft Flight Simulator

How This Combo Ranks

The AMD Ryzen 7 5800XT paired with the AMD Radeon RX 9070 XT lands at rank 440 out of 1795 tested combos in Microsoft Flight Simulator. That places this configuration in the top 25% of all combinations in the database, which is a strong showing for a flight sim known to hammer both CPU and GPU heavily. The rank reflects a balanced pairing rather than a lopsided one — neither component is obviously dragging the other down, and the measured frame rates confirm that this combo can handle the game's demands across most settings.

What stands out is how the combo's percentile positions align. The CPU sits at the 86th percentile among all processors, while the GPU holds the 82nd percentile among all graphics cards. These are closely matched, meaning the system is unlikely to experience severe bottlenecking in either direction. In a game like Microsoft Flight Simulator, where draw calls and scenery streaming can spike CPU usage while GPU load varies with weather and terrain, this kind of equilibrium is valuable. The data shows a setup that performs consistently rather than one that excels in isolated scenarios but falters in others.

GPU Role

The Radeon RX 9070 XT brings 16 GB of GDDR6 memory on a 256-bit bus, with memory bandwidth rated at 644.6 GB/s. In Microsoft Flight Simulator, VRAM capacity matters because the game streams high-resolution textures for terrain, aircraft, and buildings. The 16 GB frame buffer ensures that even at 4K with Ultra presets, the card is unlikely to run out of memory, which is a common cause of stuttering in this title. The memory clocks run at 2518 MHz, translating to 20.1 Gbps effective, which helps feed the 4096 shading units at a steady pace.

The GPU's clock behavior is worth noting. The base clock sits at 1660 MHz, but the boost clock reaches 2970 MHz, with a game clock of 2400 MHz. In practice, the card will spend most of its time near the game clock during sustained loads, and the boost headroom allows for short bursts of higher performance when scenery complexity spikes. The architecture is RDNA 4.0 on a 4 nm process, with 64 ray accelerators — though ray tracing is not a primary factor in Flight Simulator's measured results. The pixel rate of 380.2 GPixel/s and texture rate of 760.3 GTexel/s are more relevant here, as the game relies heavily on fill rate for rendering dense cockpit instruments and ground detail.

When compared to its nearest rivals in the benchmark database, the RX 9070 XT's average score of 39647 is within 0.6% of the AMD Radeon Pro 575X, which posts 39836. It also edges out the NVIDIA RTX A500 Mobile by 0.2% and the AMD Radeon Pro 575 by 0.1%. These deltas are negligible, meaning the card's raw compute performance is essentially on par with those alternatives, but the 16 GB VRAM and modern RDNA 4.0 feature set give it an edge in a VRAM-hungry sim like this one.

CPU Role

The Ryzen 7 5800XT is an 8-core, 16-thread processor based on Zen 3 architecture, codenamed Vermeer, built on TSMC's 7 nm process. It has a base clock of 3.80 GHz and a boost clock of 4.80 GHz, with 32 MB of L3 cache. For Microsoft Flight Simulator, the single-thread performance is critical because the game's main simulation loop — flight physics, weather calculations, and AI traffic — runs on a limited number of threads. The CPU's 3dmark_single_thread score of 959 and cinebench_r23_singlecore score of 3359 indicate strong per-core performance, which translates directly to smoother frame pacing in CPU-bound scenarios.

Multi-threaded performance is also solid, with a cinebench_r23_multicore score of 23794 and a passmark_multithread score of 27988. This matters for Flight Simulator because the game does spread some workload across cores, particularly when rendering complex airport environments with many buildings and ground vehicles. The 16 threads allow the CPU to handle background tasks like scenery loading without stealing cycles from the main simulation thread. The L3 cache of 32 MB is generous and helps with the game's tendency to repeatedly access the same texture and object data.

The CPU's benchmark scores place it just 0.3% behind the AMD Ryzen 7 7840H (29868 average) and 0.3% ahead of the AMD Ryzen AI 7 PRO 360 (29682). It also trades blows with the AMD Ryzen 7 PRO 5755GE, which scores 29740, a 0.1% delta. These are all close competitors, but the 5800XT's advantage in this pairing is its compatibility with DDR4 memory — the system can run dual-channel at 51.2 GB/s, which is sufficient for feeding the GPU without creating a memory bandwidth bottleneck.

Measured FPS Breakdown

At 1080p, the combo delivers playable to excellent frame rates across all settings. Low preset hits 165 FPS average, which is well above any display refresh rate for competitive or casual play. Medium drops to 128.5 FPS, High to 99.1 FPS, and Ultra to 93 FPS. The gap between Low and Ultra is 72 FPS, showing that the GPU has headroom at this resolution, but the CPU starts to become a factor at lower settings where frame rates exceed 120.

Moving to 1440p, the numbers remain strong. Low preset averages 128.7 FPS, Medium hits 99.9 FPS, High lands at 74.8 FPS, and Ultra drops to 72.6 FPS. The delta between Low and Ultra here is 56.1 FPS, a smaller spread than at 1080p, which indicates the GPU is taking on more of the load as resolution increases. The step from High to Ultra at 1440p is only 2.2 FPS, suggesting that the Ultra preset's additional effects are not heavily taxing the GPU at this resolution.

At 4K, the combo still holds its own. Low preset averages 97.7 FPS, which is respectable for 4K in a flight sim. Medium drops to 76.9 FPS, High to 55.6 FPS, and Ultra to 53.5 FPS. The spread from Low to Ultra is 44.2 FPS, the smallest of the three resolutions, confirming that the GPU is the limiting factor at 4K. The High and Ultra results are both above 50 FPS, which is playable for a sim where frame rates in the 50s are often tolerated due to the slower-paced gameplay.

Resolution Scaling

The scaling from 1080p to 4K reveals the bottleneck dynamics clearly. At Low settings, the frame rate drops from 165 FPS at 1080p to 128.7 FPS at 1440p and then to 97.7 FPS at 4K. That is a 40.8% reduction from 1080p to 4K, which is a larger percentage drop than the pure pixel count increase would suggest — 4K has 4 times the pixels of 1080p. This indicates that at Low settings, the CPU is still a significant factor, and the GPU has enough headroom that the resolution scaling does not fully saturate it.

At Ultra settings, the scaling is different. The frame rate goes from 93 FPS at 1080p to 72.6 FPS at 1440p and then to 53.5 FPS at 4K. That is a 42.5% reduction from 1080p to 4K, but the absolute values are much lower. The fact that Ultra at 1080p only reaches 93 FPS, compared to 165 FPS at Low, shows that the Ultra preset's effects — likely higher shadow quality, more detailed clouds, and increased draw distance — are heavily taxing the GPU even at lower resolutions. The GPU becomes the clear limiting component at Ultra across all resolutions, while the CPU is more relevant at Low and Medium presets.

The 1440p results sit almost exactly in the middle between 1080p and 4K for all presets, which is expected given the pixel count. What is notable is that the difference between High and Ultra at 1440p (2.2 FPS) is smaller than at 1080p (6.1 FPS) and 4K (2.1 FPS). This suggests that at 1440p, the system reaches a sweet spot where neither the CPU nor the GPU is severely stressed, and the Ultra preset's additional load is absorbed without a large frame rate hit.

Settings Recommendations

For the best experience, the data points to 1440p with High settings as the balanced choice. At 1440p High, the combo averages 74.8 FPS, which is smooth for a flight sim and leaves headroom for weather changes or busy airport scenery that can cause dips. The jump to Ultra at 1440p only costs 2.2 FPS (72.6 FPS), so if visual fidelity is the priority, Ultra is effectively free at this resolution. There is no reason to run Medium at 1440p (99.9 FPS) unless you are targeting very high refresh rates, but the visual difference between Medium and High is substantial in this game.

At 1080p, the recommendation is High settings (99.1 FPS) or Ultra (93 FPS). Both are comfortably above 90 FPS, and the difference of 6.1 FPS is worth accepting Ultra for the improved draw distance and cloud rendering. Running Low at 1080p (165 FPS) is only sensible if you are chasing maximum frame rates for a high-refresh display, but the game's visual identity suffers significantly at Low.

At 4K, the situation is more nuanced. Ultra averages 53.5 FPS, which is playable but close to the edge of smoothness for a sim where you may want to pan the camera quickly. High at 4K (55.6 FPS) is nearly identical, so there is no benefit to dropping from Ultra to High — you lose visual quality for essentially the same frame rate. Medium at 4K (76.9 FPS) is the better option if you want a comfortable margin above 60 FPS, and it still looks far better than Low (97.7 FPS), which sacrifices too much detail for the resolution.

The overall best experience per the measured rows is 1440p Ultra at 72.6 FPS. It delivers the highest visual fidelity without dropping below 70 FPS, and the CPU-GPU balance at this resolution means the system is not leaving performance on the table. For users with a 4K display, Medium settings at 4K (76.9 FPS) provide the best trade-off between immersion and smoothness.
