# Microsoft Flight Simulator with AMD Ryzen 7 5700X + AMD Radeon RX 7900 XTX

This combo pairs an 8-core, 16-thread AMD Ryzen 7 5700X with the flagship Radeon RX 7900 XTX, producing measured frame rates that reveal a heavily GPU-bound title at higher resolutions. The data shows a system capable of excellent 1080p performance, but the scaling pattern across settings and resolutions tells a more nuanced story about where the bottleneck lies in this flight simulator.

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

The AMD Ryzen 7 5700X brings 8 cores and 16 threads based on Zen 3 architecture, with a base clock of 3.40 GHz and boost clock of 4.60 GHz. This 7 nm Vermeer chip sits in the 5000 series family, supporting DDR4 memory with dual-channel bandwidth of 51.2 GB/s. Its 32 MB shared L3 cache and 512 KB L2 per core provide the memory hierarchy needed for simulation workloads that often involve streaming terrain and aircraft systems data.

Benchmark results place this CPU in the 83rd percentile against all processors, with an average benchmark score of 26214. Its nearest rivals show tight competition: the Intel Core i9-11900KF scores 26196 (deltaPct 0.1), while the AMD Ryzen 5 7600X scores 26272 (deltaPct -0.2). This clustering indicates the 5700X delivers compute performance squarely in the mid-high range, with 3DMark multi-threaded scores reaching 6858 and Cinebench R23 multi-core at 22620.

In Microsoft Flight Simulator, the CPU's role becomes apparent when examining the FPS deltas between settings at the same resolution. At 1080p, dropping from Ultra (106.5 FPS) to Low (176.8 FPS) yields a 66% performance increase, suggesting the CPU can feed frames faster when the GPU workload is lightened. However, at 4K, the same settings change produces only a 68% gain (64.6 to 108.7 FPS), indicating that at higher resolutions the GPU becomes the primary limiter, while the CPU still has headroom. The single-thread score of 921 in 3DMark and 3193 in Cinebench R23 suggests this processor handles the simulation's primary thread reasonably well, though it is not class-leading.

Settings Recommendations — which preset gives the best experience per the measured rows

The measured data provides clear guidance for optimizing the experience. At 1080p, the High preset delivers 110.8 FPS, while Ultra drops to 106.5 FPS — a marginal 4 FPS difference. The Medium preset at 151 FPS offers a substantial 36% improvement over High while maintaining visual quality that is likely acceptable for most users. Low at 176.8 FPS is the fastest but sacrifices the visual fidelity that makes flight simulation immersive.

At 1440p, the pattern shifts. High produces 86.7 FPS, Medium 120 FPS, and Low 152.6 FPS. The jump from High to Medium (33.3 FPS gain) is more significant than the jump from Medium to Low (32.6 FPS gain), suggesting Medium represents the sweet spot for balanced performance. Ultra at 85.4 FPS is only 1.3 FPS behind High, making High and Ultra nearly interchangeable at this resolution.

For 4K, High achieves 66.7 FPS, which is playable but not smooth by competitive standards. Medium at 88.4 FPS provides a comfortable margin above 60 FPS, while Ultra drops to 64.6 FPS — just above the 60 FPS threshold. Given that Medium at 4K is 32% faster than High and 37% faster than Ultra, it represents the recommended preset for 4K users seeking consistent frame rates without severe visual compromise.

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

The resolution scaling data reveals the GPU-bound nature of this title. At Low settings, FPS drops from 176.8 at 1080p to 152.6 at 1440p (a 13.7% reduction) and then to 108.7 at 4K (a 38.5% reduction from 1440p). This steep drop at 4K indicates the RX 7900 XTX's rendering load scales significantly with pixel count.

At High settings, the progression is 110.8 → 86.7 → 66.7 FPS, representing a 21.7% drop from 1080p to 1440p and a 23.1% drop from 1440p to 4K. The consistent percentage drops across these steps suggest the GPU is the primary constraint, with the CPU maintaining adequate frame delivery even at lower resolutions.

Ultra settings show a similar pattern: 106.5 → 85.4 → 64.6 FPS. The fact that Ultra at 1080p (106.5 FPS) is only 60% of Low at 1080p (176.8 FPS) demonstrates that the game's visual effects at Ultra place a significant load on the GPU, independent of resolution. The narrowing gap between High and Ultra at higher resolutions (4.1 FPS difference at 1080p, 1.3 FPS at 1440p, 2.1 FPS at 4K) suggests that Ultra's additional effects become less impactful as the GPU becomes more pixel-bound.

How This Combo Ranks — use comboRankInGame vs other tested combos

This specific combination of AMD Ryzen 7 5700X and AMD Radeon RX 7900 XTX ranks 255th out of 1795 tested combos in Microsoft Flight Simulator, placing it in the 85.8th percentile of all tested systems. This rank reflects the strong GPU contribution, as the RX 7900 XTX itself sits in the 85th percentile against all GPUs with an average benchmark score of 44019.

The GPU's nearest rivals include the AMD Radeon Pro 580 (avg score 44195, deltaPct -0.4), NVIDIA GeForce RTX 4090 Mobile (43667, deltaPct 0.8), and NVIDIA GeForce RTX 4070 Ti (44900, deltaPct -2). The RX 7900 XTX outperforms the RTX 4090 Mobile by 0.8% but trails the RTX 4070 Ti by 2%. This competitive positioning explains why the combo ranks in the top 15% despite the CPU being in the 83rd percentile — the GPU is the dominant factor in this game's performance.

The 255th rank out of 1795 combos means there are 254 configurations that deliver higher FPS in this title, likely featuring faster CPUs paired with this or similar GPUs. However, given that the CPU's average benchmark score is within 0.2% of rivals like the Ryzen 5 7600X, the performance difference in-game would be minimal. The data suggests this combo is well-balanced for Flight Simulator, with neither component severely bottlenecking the other at typical gaming resolutions.

GPU Role — VRAM, clocks, and how they relate to this game's results

The AMD Radeon RX 7900 XTX serves as the performance anchor for this combo. Built on RDNA 3.0 architecture with the Navi 31 chip, this GPU features 24 GB of GDDR6 memory on a 384-bit bus, delivering 960.0 GB/s of bandwidth. Its 6144 shading units, 384 TMUs, and 192 ROPs provide substantial raw compute capability, with FP32 performance rated at 61.39 TFLOPS.

Clock speeds reach a base of 1929 MHz and boost up to 2498 MHz, with a game clock of 2365 MHz. Memory runs at 2500 MHz (20 Gbps effective), which is crucial for a game like Flight Simulator that streams large textures and terrain data. The 24 GB VRAM capacity ensures no memory capacity bottlenecks at 4K Ultra settings, where texture detail can consume significant memory.

The GPU's benchmark scores demonstrate its strength: PassMark G3D scores 31238, Geekbench Vulkan scores 192597, and 3DMark Steel Nomad DX12 scores 6841. In the measured FPS data, the RX 7900 XTX's role is evident in the 4K results — at Ultra settings it maintains 64.6 FPS, which is impressive given the game's demanding nature. The GPU's performance at 1080p Low (176.8 FPS) shows it can push well beyond typical monitor refresh rates when unconstrained.

The power requirements are substantial, with a 355 W TDP and suggested 750 W PSU, using dual 8-pin connectors. The dual-slot cooler and 287 mm length make it a physically large component, but the performance justifies the footprint in this simulation title.

The data reveals a consistent pattern where Medium settings deliver substantially higher frame rates than High or Ultra at every resolution. At 1080p, Medium (151 FPS) is 36% faster than High (110.8 FPS). At 1440p, Medium (120 FPS) is 38% faster than High (86.7 FPS). At 4K, Medium (88.4 FPS) is 32% faster than High (66.7 FPS). This consistent 32-38% advantage makes Medium the standout preset for users prioritizing frame rate stability.

Low settings provide the highest ceiling, reaching 176.8 FPS at 1080p, but the visual trade-off is significant. The progression from Low to Medium at each resolution shows a 14.6% drop at 1080p (176.8 to 151), 21.4% drop at 1440p (152.6 to 120), and 18.7% drop at 4K (108.7 to 88.4). These percentages suggest that Medium retains most of the performance while adding meaningful visual improvements. The Ultra preset, by contrast, offers only marginal gains over High — just 4.1 FPS at 1080p and 1.3 FPS at 1440p — making High the more efficient choice for those who want maximum quality without the slight Ultra penalty.
