# Microsoft Flight Simulator: AMD Ryzen 7 5800XT + AMD Radeon RX 9070

This pairing brings an 8-core Zen 3 processor together with a RDNA 4.0 GPU, and the measured frame rates across resolutions reveal a system that scales predictably with workload. The combo ranks 571st out of 1795 tested configurations, placing it comfortably in the upper third of all combinations. What stands out immediately is how the FPS deltas between Low and Ultra settings compress as resolution climbs — a classic sign of the GPU taking over as the primary constraint at higher pixel counts.

Resolution Scaling

The FPS drop from 1080p to 4K follows a steep but consistent curve. At Low settings, the average frame rate falls from 152.6 at 1920x1080 to 126.2 at 2560x1440, then plunges to 89.1 at 3840x2160. That represents a 41.6% reduction from 1080p to 4K at Low. At Ultra settings, the decline is shallower in absolute terms: 87.8 at 1080p, 68.9 at 1440p, and 52.1 at 4K — a 40.7% drop from 1080p to 4K. The similarity in these percentages suggests the GPU is the limiting factor even at 1080p Ultra, though the CPU still has headroom.

The Medium preset tells a more revealing story. At 1080p Medium, the system delivers 122.7 FPS, which falls to 99.1 at 1440p (a 19.2% drop) and then to 69.6 at 4K (a 29.8% drop from 1440p). This non-linear scaling indicates that the transition from 1440p to 4K imposes a disproportionately heavier load on the GPU, while the 1080p to 1440p step is less punishing. The data implies that at 1080p and 1440p Medium, the CPU still contributes meaningfully to frame delivery, but at 4K the GPU becomes the definitive bottleneck.

High settings follow a similar pattern: 91.6 at 1080p, 72.1 at 1440p, and 50.3 at 4K. The 4K High result is notably close to the 4K Ultra result (52.1), suggesting diminishing returns from the High-to-Ultra transition at that resolution. The scaling behavior indicates that for this flight simulator, 4K gaming will consistently land in the 50-89 FPS range depending on preset, while 1440p offers the widest playable envelope.

CPU Role

The AMD Ryzen 7 5800XT contributes 8 cores and 16 threads from the Zen 3 architecture, with a base clock of 3.80 GHz and a boost clock of 4.80 GHz. Its 32 MB of L3 cache and dual-channel DDR4 memory support at 51.2 GB/s bandwidth provide adequate feeding for the GPU. The processor's benchmark profile shows a 3DMark 16-thread score of 7683 and a single-thread score of 959, which places it in the 86th percentile of all CPUs.

The CPU's role in this game becomes evident when examining the frame rates at lower resolutions. At 1080p Low, the system reaches 152.6 FPS, which is the highest measured value across all configurations. This indicates the CPU can drive high frame rates when the GPU is not heavily taxed. However, the single-thread performance (959 in 3DMark single-thread, 3359 in Cinebench R23 single-core) suggests that simulation-heavy scenes in Microsoft Flight Simulator could strain individual cores. The multi-threaded capabilities (Cinebench R23 multi-core score of 23794) provide headroom for background tasks and complex scenes.

Compared to its nearest rivals, the 5800XT sits within 0.3% of the AMD Ryzen 7 7840H and AMD Ryzen 7 6800HS in average benchmark scores. This tight clustering means the CPU is not an outlier in either direction. The 5800XT's 8-core configuration is well-suited for a flight simulator that benefits from multiple threads, but the data suggests that at 4K, the CPU's influence on frame rates diminishes significantly — the GPU becomes the dominant factor.

GPU Role

The AMD Radeon RX 9070 brings 16 GB of GDDR6 memory on a 256-bit bus, yielding 644.6 GB/s of bandwidth. Its RDNA 4.0 architecture with 3584 shading units and 128 ROPs delivers a boost clock of 2520 MHz. The GPU's passmark G3D score of 25381 and 3DMark Steel Nomad DX12 score of 6290 put it in the 79th percentile of all GPUs.

The 16 GB VRAM capacity is particularly relevant for Microsoft Flight Simulator, which is known for loading extensive terrain and aircraft data. The measured frame rates show that the GPU handles 4K Ultra at 52.1 FPS, which is playable but not smooth by competitive standards. At 1080p Low, the GPU pushes 152.6 FPS, demonstrating its raw throughput capability when not constrained by resolution.

Interestingly, the GPU's nearest rivals in average benchmark scores include the NVIDIA A2 (within 0.2%) and the AMD Radeon PRO W6400 (within 0.8%). These comparisons are based on synthetic benchmarks, but the in-game results show the RX 9070 delivering consistent frame rates across all settings. The GPU's memory bandwidth of 644.6 GB/s appears sufficient for this title, as the frame rate drops from 1080p to 4K are proportional to the pixel count increase rather than showing a sudden cliff that would indicate memory capacity issues.

Measured FPS Breakdown

At 1920x1080, the system delivers a wide spread of results: 152.6 FPS at Low, 122.7 FPS at Medium, 91.6 FPS at High, and 87.8 FPS at Ultra. The gap between Low and Medium is 29.9 FPS, while the gap between High and Ultra is only 3.8 FPS. This suggests that the High preset captures most of the visual fidelity gains without the performance penalty of Ultra.

Moving to 2560x1440, the numbers shift to 126.2 FPS at Low, 99.1 FPS at Medium, 72.1 FPS at High, and 68.9 FPS at Ultra. The Low-to-Medium gap narrows to 27.1 FPS, while High-to-Ultra remains tight at 3.2 FPS. The 1440p results show that even at Ultra, the system maintains nearly 69 FPS, which is smooth for a flight simulator.

At 3840x2160, the results compress further: 89.1 FPS at Low, 69.6 FPS at Medium, 50.3 FPS at High, and 52.1 FPS at Ultra. Notice that at 4K, the High and Ultra results are essentially identical within a margin of 1.8 FPS, while Medium offers a significant 19.3 FPS advantage over High. This inversion suggests that the High preset at 4K may include settings that are disproportionately expensive on the GPU, making Medium the more efficient choice at that resolution.

How This Combo Ranks

With a combo rank of 571 out of 1795 tested configurations, this pairing sits in the 68th percentile of all combinations. The rank reflects a balanced system where neither component dramatically overperforms or underperforms relative to the other. The CPU's 86th percentile standing and the GPU's 79th percentile standing combine to produce a system that is stronger than the average combo but not at the top tier.

The rank suggests that in the broader context of tested systems, there are 570 combinations that outperform this one, but also 1224 that it beats. This places the system in the upper third, which is respectable for a mid-generation pairing. The data implies that users seeking higher ranks would need to pair the RX 9070 with a stronger CPU or vice versa, but the current combination delivers consistent frame rates across the tested settings.

Settings Recommendations

Based on the measured rows, the optimal preset depends heavily on resolution. At 1080p, the High preset (91.6 FPS) offers a strong balance, as stepping to Ultra only provides a marginal visual gain while costing 3.8 FPS. At 1440p, the Medium preset (99.1 FPS) is the sweet spot, delivering over 30 FPS more than High while maintaining smoothness. At 4K, the Medium preset (69.6 FPS) is clearly the recommended choice, as High and Ultra both drop below 55 FPS with negligible visual differences between them.

For users prioritizing maximum visual fidelity, 1440p Ultra at 68.9 FPS is the highest-quality setting that remains playable. At 4K, even Low settings (89.1 FPS) require a compromise on visuals, but Medium provides the best balance of fidelity and performance. The data strongly indicates that 4K Ultra is not advisable for this combo, given the 52.1 FPS result and the minimal improvement over High.
