# Microsoft Flight Simulator — AMD Ryzen 7 5800X + AMD Radeon RX 9070

This combination of an AMD Ryzen 7 5800X and AMD Radeon RX 9070 produces a clear hierarchy of performance across resolutions and settings in Microsoft Flight Simulator, with the data revealing where the bottleneck shifts between CPU and GPU as workload intensity changes. The measured frames per second (FPS) range from a demanding 52.6 at 4K Ultra to a fluid 157.4 at 1080p Low, showing that this pairing can span the spectrum from visually rich simulation to high-refresh-rate flying. The combo ranks 561st out of 1,795 tested combinations, placing it in the upper third of all tested systems while still leaving headroom for more powerful configurations.

Resolution Scaling

The FPS drop from 1080p to 4K is steep and consistent, indicating that the GPU becomes the dominant limiting factor at higher resolutions. At High settings, the average FPS falls from 89.0 at 1920x1080 to 75.4 at 2560x1440, a reduction of 13.6 FPS, then further to 53.4 at 3840x2160 — meaning 4K High delivers roughly 60% of the 1080p High performance. This pattern intensifies at Ultra settings, where 1080p produces 84.8 FPS, 1440p drops to 66.6 FPS, and 4K falls to 52.6 FPS, representing a 38% loss from 1080p to 4K. The scaling suggests that the RX 9070's 16 GB of GDDR6 memory and 644.6 GB/s bandwidth are sufficient for the data demands, but the raw compute throughput of 36.13 TFLOPS becomes the ceiling at higher pixel counts.

Interestingly, the Low preset shows a different scaling curve. At 1080p Low, the combo reaches 157.4 FPS, and even at 4K Low it maintains 91.7 FPS — a much shallower drop of 42% from 1080p to 4K compared to the 50% drop at Ultra. This indicates that at Low settings, the CPU's single-thread performance begins to matter more, as the reduced graphics load allows the Ryzen 7 5800X's 4.70 GHz boost clock to keep up more effectively. The 1440p Medium result of exactly 100.0 FPS sits neatly between the 1080p Medium at 124.0 and 4K Medium at 67.8, reinforcing that resolution scaling is nearly linear for this game at medium workloads.

Settings Recommendations

The measured data points to High as the most balanced preset for this combination, particularly at 1440p where it delivers 75.4 FPS — comfortably above the 60 FPS threshold for smooth flight simulation. At 1080p, High produces 89.0 FPS, which is excellent for a game where camera panning and ground detail are frequent, while 4K High at 53.4 FPS is playable but noticeably below the smoothness most users would prefer. The Ultra preset offers only marginal visual gains over High in this game's engine, yet it costs 15.6% of performance at 1080p (84.8 vs 89.0) and 1.5% at 4K (52.6 vs 53.4) — the latter difference being almost negligible, suggesting that at 4K the GPU is already saturated and the extra settings cost little.

For users prioritizing frame rate, Medium at 1080p yields 124.0 FPS, which is 39% faster than High, and at 1440p Medium hits exactly 100.0 FPS — a sweet spot for high-refresh monitors. Low settings push performance to 157.4 FPS at 1080p and 123.3 FPS at 1440p, but the visual compromise in a flight simulator — where cockpit readability and terrain clarity matter — likely outweighs the FPS gain for most. The data suggests that High at 1080p or 1440p is the recommended starting point, with Medium as a fallback for demanding scenes, and Ultra reserved for 4K users who accept the 52.6 FPS result.

GPU Role

The Radeon RX 9070's specifications directly explain several observed behaviors. With 16 GB of GDDR6 memory on a 256-bit bus, the card provides 644.6 GB/s of bandwidth, which appears sufficient for Microsoft Flight Simulator's streaming terrain and aircraft models — none of the resolution steps show catastrophic FPS collapses that would indicate memory capacity limits. The boost clock of 2520 MHz and game clock of 2070 MHz drive the 3584 shading units, and the FP32 throughput of 36.13 TFLOPS is the likely performance ceiling at 4K, where the Ultra preset's 52.6 FPS and High's 53.4 FPS are nearly identical, implying that the GPU is compute-bound rather than settings-bound at this resolution.

The GPU's 79th percentile ranking among all GPUs and average benchmark score of 34,780 place it in the upper tier, yet its nearest rivals — such as the NVIDIA A2 with a deltaPct of -0.2 and the Quadro GV100 at +0.3 — are professional or data-center cards, not gaming-focused alternatives. This suggests that the RX 9070's gaming performance is somewhat specialized; in Microsoft Flight Simulator, the measured results show it can handle 1440p High at 75.4 FPS but struggles to maintain 60 FPS at 4K Ultra. The 56 ray accelerators and DirectX 12 Ultimate support are present, but the game's reliance on traditional rasterization means these features likely contribute little to the measured FPS.

Measured FPS Breakdown

At 1920x1080, the four presets deliver: Low at 157.4 FPS, Medium at 124.0 FPS, High at 89.0 FPS, and Ultra at 84.8 FPS. The step from Medium to High is the largest single drop at 35 FPS, while High to Ultra costs only 4.2 FPS — a pattern that repeats at other resolutions, indicating that High captures most of the visual fidelity with a manageable performance hit. Moving to 2560x1440, the numbers shift to 123.3 FPS at Low, 100.0 FPS at Medium, 75.4 FPS at High, and 66.6 FPS at Ultra. The 1440p Medium result of exactly 100.0 FPS is notable for high-refresh 1440p monitors, though the 1440p Ultra figure of 66.6 FPS shows that the most demanding preset begins to strain at this resolution.

At 3840x2160, the performance compresses significantly: Low produces 91.7 FPS, Medium drops to 67.8 FPS, High falls to 53.4 FPS, and Ultra bottoms out at 52.6 FPS. The near-parity between High and Ultra at 4K (0.8 FPS difference) is a statistical tie, suggesting that the GPU is fully saturated and additional settings have diminishing returns. The overall pattern across all 12 data points shows that the combo loses roughly 40-45% of its 1080p performance when moving to 4K, regardless of settings, which is a typical GPU-bound scaling curve for a demanding simulator.

CPU Role

The Ryzen 7 5800X brings 8 cores and 16 threads based on the Zen 3 architecture, with a base clock of 3.80 GHz and boost clock of 4.70 GHz. Its 32 MB of L3 cache and 4,150 million transistors on a 7 nm process from TSMC contribute to a strong single-thread performance, as seen in the 3DMark single-thread score of 943 and Cinebench R23 single-core score of 3,327. These single-thread metrics matter for flight simulators, which often rely on a primary simulation thread; the data supports this, as the combo achieves 157.4 FPS at 1080p Low, where CPU overhead is more likely to limit performance than the GPU.

The CPU's 84th percentile ranking among all CPUs and average benchmark score of 27,606 show it is slightly above average, with nearest rivals including the AMD Ryzen 7 5800 at +0.3% and Intel Core i5-12600KF at -0.8%. In multithreaded tests, the 16 threads deliver a Cinebench R23 multicore score of 23,571, but the game's scaling appears to favor the single-thread score, as FPS does not increase linearly with thread count. The measured FPS at 1080p Ultra (84.8) versus 1080p High (89.0) suggests that as GPU load decreases, the CPU's 4.70 GHz boost clock becomes the limiting factor, keeping performance from rising above the 157.4 FPS ceiling seen at Low settings.

How This Combo Ranks

In Microsoft Flight Simulator, this specific CPU-GPU pairing achieves a rank of 561 out of 1,795 total tested combinations, placing it in the 68.7th percentile of all combos. This ranking reflects a balanced but not top-tier configuration: the GPU's 79th percentile and CPU's 84th percentile individually are higher than the combo's game-specific percentile, indicating that the game's engine does not fully utilize both components' strengths. The measured FPS data shows that the combo excels at 1080p and 1440p with High or Medium settings, where it delivers 89.0 and 75.4 FPS respectively, but falls short of the highest-tier combos at 4K Ultra, where 52.6 FPS is below the 60 FPS threshold many simmers target.

Compared to other tested combos, the 561st rank suggests that many systems with newer or higher-end components outperform this pairing in this specific title. The gap between the CPU's strong single-thread benchmarks (e.g., Geekbench single-core score of 2,194) and the game's modest FPS scaling implies that Microsoft Flight Simulator's engine may not fully exploit the 5800X's capabilities, or that the RX 9070's 36.13 TFLOPS is insufficient for the highest settings at 4K. The rank also reflects that while this combo handles 1080p Low at 157.4 FPS — a result many systems would envy — the game's demanding nature at higher presets pulls the overall ranking down relative to the component's individual standings.
