# Microsoft Flight Simulator: AMD Ryzen 5 3600 + AMD Radeon RX 7900 XTX

This pairing of AMD's six-core Ryzen 5 3600 with the flagship Radeon RX 7900 XTX delivers a playable flight sim experience across all tested presets, though the data reveals a significant performance ceiling at 4K Ultra that falls just short of the 60 FPS mark. The combo ranks 395th out of 1,795 tested configurations, placing it in the top 22% of all systems evaluated, with the GPU's 85th percentile standing against all GPUs outweighing the CPU's 76th percentile ranking.

Settings Recommendations

The measured FPS data across three resolutions and four quality presets shows a clear pattern: Medium settings at 1440p or 1080p provide the best balance of fluidity and visual fidelity. At 1920x1080, the Medium preset delivers 126.4 FPS average, which is only 10.4 FPS behind the Low preset's 136.8 FPS but represents a substantial jump in visual quality over Low. Moving to 2560x1440, Medium produces 113.4 FPS average, remaining far above the 60 FPS threshold while High drops to 90.1 FPS and Ultra falls to 82.5 FPS.

For users prioritizing maximum smoothness, the Low preset at 1080p reaches 136.8 FPS, but the jump from Low to Medium costs only 10.4 FPS at 1080p and 9.4 FPS at 1440p, making Medium the sensible default. At 4K, the situation becomes more constrained: Medium yields 86.4 FPS, which is the highest 4K average among the non-Low presets, while High drops to 62.4 FPS and Ultra falls to 59.6 FPS. The 4K Low preset hits 111.1 FPS, but the visual compromise is severe for a flight sim where terrain detail matters.

The data suggests that 1440p Medium is the sweet spot for this combo, offering 113.4 FPS with enough headroom for complex scenery. At 4K, Medium is the only preset that comfortably exceeds 60 FPS, with High and Ultra both hovering near or below the 60 FPS line. Users with high-refresh 1080p displays can push to High at 113.6 FPS, which is nearly identical to the 1440p Medium result, indicating the CPU begins to limit at lower resolutions.

CPU Role

The AMD Ryzen 5 3600 brings six cores and twelve threads based on the Zen 2 architecture, with a base clock of 3.60 GHz and a boost clock of 4.20 GHz. This 3000-series processor, built on TSMC's 7 nm process, shows its age in synthetic benchmarks relative to modern rivals. In Cinebench R23, the multicore score of 15,045 and single-core score of 2,124 indicate a processor that remains capable for gaming but lags newer designs.

The CPU's nearest rivals in average benchmark score include the Intel Core i5-11400 at 18,150 (deltaPct -0.1), the AMD Ryzen 5 7535HS at 18,101 (deltaPct 0.2), the AMD Ryzen 5 1600 at 18,158 (deltaPct -0.2), and the AMD EPYC 9274F at 18,189 (deltaPct -0.3). These deltas are all within 0.3%, meaning the Ryzen 5 3600 performs essentially on par with these processors in aggregate benchmarks, despite architectural differences.

In Microsoft Flight Simulator, the CPU's influence becomes evident when comparing resolution scaling. At 1080p, the difference between Low and Ultra is 31.1 FPS (136.8 to 105.7), while at 1440p the spread is 40.3 FPS (122.8 to 82.5), and at 4K it reaches 51.5 FPS (111.1 to 59.6). This widening gap at higher resolutions indicates the GPU becomes the primary bottleneck as pixel count increases, while the CPU maintains relatively consistent performance across settings.

The single-thread performance, measured at 696 in 3DMark single-thread and 2,562 in PassMark single-thread, likely constrains maximum frame rates in CPU-bound scenarios like low-resolution gameplay. However, the 12 threads provide sufficient parallelism for the flight sim's background simulation tasks. The 32 MB of shared L3 cache helps maintain data locality, though it is not the 3D V-Cache design seen in later AMD parts.

GPU Role

The AMD Radeon RX 7900 XTX is a RDNA 3.0 flagship featuring the Navi 31 chip, built on TSMC's 5 nm process with 57,700 million transistors. Its 24 GB of GDDR6 memory on a 384-bit bus provides 960.0 GB/s of bandwidth, which proves critical for 4K textures in a dense flight sim environment. The GPU's boost clock of 2498 MHz and game clock of 2365 MHz deliver substantial compute throughput, with FP32 performance rated at 61.39 TFLOPS.

The GPU's benchmark standing shows an 85th percentile against all GPUs, with an average benchmark score of 44,019. Its nearest rivals include the AMD Radeon Pro 580 (deltaPct -0.4), the NVIDIA GeForce RTX 4090 Mobile (deltaPct 0.8), the NVIDIA Quadro M6000 (deltaPct 1.6), and the NVIDIA GeForce RTX 4070 Ti (deltaPct -2). These deltas indicate the RX 7900 XTX performs within 2% of these competing products in aggregate GPU benchmarks.

In Microsoft Flight Simulator, the GPU's 24 GB VRAM capacity is unlikely to be a limiting factor at any tested setting, as the game's texture requirements at 4K Ultra fall well within this allocation. The 960.0 GB/s memory bandwidth supports the game's streaming-heavy design, where terrain and photogrammetry data must be loaded rapidly as the aircraft moves.

The GPU's performance scaling across resolutions reveals its dominance: at 1080p High, the combo achieves 113.6 FPS, while at 1440p High it drops to 90.1 FPS, and at 4K High it reaches 62.4 FPS. The 4K Ultra result of 59.6 FPS shows the GPU's limits under maximum load, but the fact that 4K Medium hits 86.4 FPS demonstrates substantial headroom. The GPU's 192 ROPs and 96 RT cores contribute to its ability to handle the game's rendering demands, though flight sims rely less on ray tracing than other genres.

How This Combo Ranks

The combo's rank of 395 out of 1,795 tested combinations places it in the top 22% of all systems evaluated in this game. This ranking reflects the synergy between a mid-range 2019 CPU and a flagship 2022 GPU, where the GPU carries most of the performance weight. The CPU's 76th percentile standing against all CPUs and the GPU's 85th percentile suggest that the pairing is GPU-heavy, which is appropriate for a flight sim that scales well with GPU resources.

When examining the measured FPS data relative to the combo's rank, the 1440p Medium result of 113.4 FPS stands out as particularly strong, likely exceeding many higher-ranked combos that may have faster CPUs but less capable GPUs. The 1080p Low result of 136.8 FPS shows the ceiling of what this combination can achieve, but this preset is unlikely to be the primary use case for a GPU of this caliber.

The rank of 395 becomes more meaningful when considering that many of the 1,400 combos ranked higher likely include newer CPUs with stronger single-thread performance. The Ryzen 5 3600's 3DMark single-thread score of 696 and PassMark single-thread score of 2,562 are modest by 2024 standards, yet the combo still outperforms the vast majority of systems in this game due to the RX 7900 XTX's raw power. Users upgrading from weaker GPUs will notice the most significant gains at 4K, where the GPU's 960.0 GB/s bandwidth and 24 GB VRAM shine.
