# How This Combo Ranks

The AMD Ryzen 5 3600 paired with the AMD Radeon RX 9070 lands at rank 1193 out of 3714 tested combos in Microsoft Flight Simulator, placing it in the 68th percentile of all configurations. That is a solidly upper-mid-tier result, though not a top-tier one. The ranking reflects a combination that handles the simulator's demands competently but leaves headroom on both sides: the CPU is a six-core Zen 2 part from 2019, while the GPU is a modern RDNA 4.0 card with substantial memory bandwidth. In this context, the combo outperforms roughly two-thirds of tested systems, which is notable given the game's reputation for stressing both processor and graphics hardware heavily.

What pushes this combo above median is the GPU's ability to maintain playable frame rates even at high resolutions. The data shows 4K Ultra at 51 FPS average, which is only slightly below the 60 FPS threshold many consider smooth. At 1440p Ultra, the average climbs to 70 FPS, and at 1080p Ultra, it reaches 86 FPS. These numbers indicate that the Radeon RX 9070 carries the load effectively at higher settings, while the Ryzen 5 3600 provides sufficient single-threaded performance for the simulator's core logic. The gap between this combo and the top-ranked ones likely stems from the CPU's age—newer processors with higher single-core clocks would push the bottleneck further toward the GPU.

CPU Role

The AMD Ryzen 5 3600 is a 6-core, 12-thread processor based on the Zen 2 architecture, manufactured on a 7nm process at TSMC. Its base clock is 3.60 GHz, boost clock is 4.20 GHz, and it has 32 MB of shared L3 cache. In synthetic benchmarks, it scores 15045 in Cinebench R23 multi-core and 2124 in single-core, with a Geekbench multi-core score of 7372 and single-core of 1536. Its Passmark multithread score is 17700, and single-thread is 2562. These numbers place it at the 71st percentile among all CPUs, with nearest rivals including the Intel Core i7-1260P (within 0.2%) and Intel Core i5-11400 (within -0.2%).

In Microsoft Flight Simulator, the CPU's role is primarily about maintaining a stable frame delivery, especially at lower resolutions where the GPU is less stressed. The data shows that at 1080p Low, the combo achieves 135 FPS average, which suggests the CPU is not severely limiting at that setting. However, the gap between Low and Ultra at 1080p is 49 FPS (from 135 down to 86), indicating that the GPU becomes more involved as settings increase. The CPU's single-thread performance, which is critical for flight simulation logic (weather, physics, AI traffic), is adequate but not exceptional—its 2124 Cinebench R23 single-core score is modest by 2025 standards. This likely explains why the combo does not crack the top quartile, as newer CPUs with higher IPC and clock speeds would reduce frame time variance in complex scenarios.

The 6-core/12-thread configuration is sufficient for the game's multi-threaded aspects, but the simulator is known to favor fewer, faster cores. The Ryzen 5 3600's 3DMark 16-thread score of 4605 shows it can handle parallel workloads, yet the single-thread score of 696 in 3DMark suggests that the primary thread may occasionally become a bottleneck, particularly in dense urban areas or complex weather systems. That said, the measured frame rates indicate that at most settings, the CPU holds up well enough to keep average FPS in playable territory.

GPU Role

The AMD Radeon RX 9070 is a RDNA 4.0 architecture GPU with 16 GB of GDDR6 memory on a 256-bit bus, providing 644.6 GB/s of bandwidth. Its boost clock is 2520 MHz, game clock is 2070 MHz, and it has 3584 shading units, 224 texture mapping units, and 128 ROPs. It supports PCIe 5.0 x16 and has a TDP of 220 W. In synthetic tests, it scores 25381 in Passmark G3D and 14737 in GPU compute, placing it at the 69th percentile among all GPUs. Its nearest rivals include the NVIDIA GeForce RTX 2080 SUPER (within -1.2%) and AMD Radeon RX 6800S (within -0.8%).

In Microsoft Flight Simulator, the GPU's role is dominant at higher resolutions and settings. The measured data shows a clear progression: at 4K, the average FPS ranges from 92 (Low) down to 51 (Ultra), while at 1080p, it ranges from 135 (Low) to 86 (Ultra). This indicates that the GPU is the primary scaling factor as resolution increases. The 16 GB VRAM is likely sufficient for the game's high-resolution textures, as the simulator is known to consume large amounts of memory at 4K with Ultra settings. The 644.6 GB/s bandwidth helps maintain texture streaming performance, which is crucial for a game that loads terrain and scenery dynamically.

The GPU's performance relative to its rivals—being within 1.2% of the RTX 2080 SUPER and 0.8% of the RX 6800S—suggests it is not a top-tier card but is competitive in this specific workload. The 4K Ultra average of 51 FPS is playable, though not ideal for a flight simulator where smooth panning is important. At 1440p High, the average of 73 FPS offers a better balance, and at 1080p High, the 91 FPS average is strong. The GPU's 36.13 TFLOPS FP32 performance is notable, but the simulator's engine may not fully utilize it, as the frame rates at 4K Ultra suggest a bottleneck that could be either the CPU or the GPU's raw throughput.

Q: Does this combo perform better at 1440p or 1080p?

A: At 1440p, the average FPS across all settings is 91.25 (average of Low, Medium, High, Ultra), while at 1080p it is 108.25. The higher average at 1080p indicates that the GPU has more headroom, but 1440p remains playable with High settings delivering 73 FPS.

Resolution Scaling

The measured data shows a clear pattern of FPS degradation as resolution increases from 1080p to 4K. At Low settings, the average FPS drops from 135 at 1080p to 125 at 1440p (a 7.4% decrease) and then to 92 at 4K (a 31.8% decrease from 1080p). At Medium settings, the averages are 121 at 1080p, 97 at 1440p, and 72 at 4K, representing a 20% drop from 1080p to 1440p and a 40.5% drop from 1080p to 4K. At High settings, the averages are 91 at 1080p, 73 at 1440p, and 54 at 4K, with drops of 19.8% and 40.7% respectively. At Ultra settings, the averages are 86 at 1080p, 70 at 1440p, and 51 at 4K, showing drops of 18.6% and 40.7%.

These percentages indicate that the scaling from 1440p to 4K is more severe than from 1080p to 1440p, which is expected given the pixel count quadruples from 1080p to 4K but only doubles from 1080p to 1440p. The fact that the drops are consistent across settings (around 40% from 1080p to 4K) suggests that the GPU is the primary limiting factor at higher resolutions. At 1080p Low, the 135 FPS average may be partially CPU-limited, as the GPU is not fully taxed at that resolution and setting combination. The data implies that the Ryzen 5 3600 can deliver enough frames per second to keep the GPU busy at 1080p, but as resolution increases, the GPU's workload grows and becomes the bottleneck.

This behavior is typical for a flight simulator, where the rendering workload scales heavily with resolution. The 4K Low average of 92 FPS is notably high, indicating that the GPU has significant headroom when settings are lowered, even at 4K. Conversely, the 4K Ultra average of 51 FPS shows that the combination of high resolution and high settings pushes the GPU to its limits.

Settings Recommendations

For this combo, the best experience depends on resolution and the user's preference for visual fidelity versus frame rate. At 1080p, the High preset provides 91 FPS average, which is smooth and visually detailed, while Ultra offers 86 FPS (5.5% lower) with marginal visual gains. At 1440p, High (73 FPS) is the sweet spot, as it stays above 70 FPS and looks significantly better than 1080p, while Ultra (70 FPS) is only 4.1% slower and may be acceptable for those who prioritize image quality. At 4K, Medium (72 FPS) is the recommended starting point, as it offers a playable frame rate with decent visuals, while High (54 FPS) and Ultra (51 FPS) dip below 60 FPS, which can be noticeable in a simulator where smooth camera movement is important.

The Low preset is not recommended for any resolution above 1080p unless the user needs maximum frame rates (e.g., 125 FPS at 1440p or 92 FPS at 4K), because the visual downgrade is substantial. The Medium preset at 1440p (97 FPS) is also a strong choice for users who want high frame rates with moderate visual quality. The data suggests that the combo's optimal performance envelope is 1080p Ultra (86 FPS) and 1440p High (73 FPS), both of which deliver a balanced experience. For 4K, Medium (72 FPS) is the only preset that clears 60 FPS, making it the default recommendation for UHD displays.

Measured FPS Breakdown

At 1920x1080, the combo achieves the following average frame rates: Low at 135 FPS, Medium at 121 FPS (with a minimum of 103 and maximum of 139), High at 91 FPS, and Ultra at 86 FPS. The spread from Low to Ultra is 49 FPS, indicating that settings have a moderate impact at this resolution. The Medium preset shows a tight min-max range (103-139), suggesting consistent frame delivery, while the lack of min/max data for other presets means we cannot assess frame time stability for those.

At 2560x1440, the average FPS values are: Low at 125, Medium at 97 (min 83, max 112), High at 73, and Ultra at 70. The drop from Low to Ultra is 55 FPS, which is slightly larger than at 1080p, reflecting the increased GPU load. The Medium preset's min-max range (83-112) indicates some variability but remains playable. The High and Ultra presets are within 3 FPS of each other, which is a small gap, suggesting that the game's Ultra preset does not add much GPU cost over High at this resolution.

At 3840x2160, the averages are: Low at 92, Medium at 72 (min 61, max 83), High at 54, and Ultra at 51. The drop from Low to Ultra is 41 FPS, and the transition from High to Ultra is only 3 FPS, showing that the Ultra preset is only slightly more demanding than High at 4K. The Medium preset's minimum of 61 FPS is reassuring, as it indicates that even in the worst-case measured frames, the combo stays above 60 FPS at Medium. The High and Ultra presets dip below 60 FPS, which may be noticeable during panning or when flying over dense scenery.

Overall, the measured data shows that this combo is best utilized at 1080p or 1440p with High or Ultra settings, while 4K requires Medium settings to maintain a consistent 60+ FPS experience. The GPU's 16 GB VRAM and high bandwidth ensure that texture streaming is not a bottleneck at any resolution, as evidenced by the relatively smooth degradation of performance from Low to Ultra at each resolution.
