# Microsoft Flight Simulator: AMD Ryzen 7 9700F + NVIDIA GeForce RTX 4070

This combo pairs AMD's Zen 5 desktop processor with NVIDIA's Ada Lovelace mid-range GPU for Microsoft Flight Simulator, a title that stresses both CPU simulation logic and GPU rendering. The data shows a system capable of smooth 4K High play, though Ultra settings at 4K push the GPU to its limits. The Ryzen 7 9700F provides strong single-thread performance for the sim's simulation engine, while the RTX 4070's 12 GB VRAM and 504.2 GB/s bandwidth handle the streaming terrain and aircraft models. This analysis breaks down how each component contributes to the measured results, where the combo ranks among 2,996 tested configurations, and what you can expect at each resolution and settings preset.

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

The AMD Ryzen 7 9700F is an 8-core, 16-thread processor built on the Zen 5 architecture (Granite Ridge) using TSMC's 4 nm process. It runs at a 3.80 GHz base clock and boosts up to 5.50 GHz, with a 65 W TDP. The CPU has 8 MB of L2 cache (1 MB per core) and 32 MB of shared L3 cache, plus dual-channel DDR5 memory support with 89.6 GB/s bandwidth. This processor's single-thread performance is critical for Microsoft Flight Simulator, which relies heavily on the main simulation thread for flight physics, autopilot logic, and scenery loading.

The CPU's benchmark results highlight its strength: a PassMark single-thread score of 4,691 and a multithread score of 36,470. The single-thread score places it at the 94th percentile among all CPUs, meaning it outperforms the vast majority of processors in lightly-threaded workloads. In Microsoft Flight Simulator, this translates directly to faster frame generation at lower resolutions where the GPU is not the bottleneck. The 5.50 GHz boost clock is especially relevant; the sim's engine frequently spikes single-core usage during complex flight phases like approach and landing, and higher clocks reduce stutter in those moments.

Compared to its nearest rivals in the PassMark database, the Ryzen 7 9700F sits within a tight performance band. The AMD Ryzen 9 7940HX scores 69,875 (0.2% higher), the Intel Core i7-14700KF scores 70,163 (0.2% higher), the AMD Ryzen 9 7950X scores 69,515 (0.7% lower), and the Intel Core i7-14700K scores 69,355 (0.9% lower). These deltas are negligible in real-world gaming, so the 9700F's advantage is not raw multithread muscle but efficiency: 8 cores at 65 W TDP versus higher-core-count rivals. For Microsoft Flight Simulator, the 8-core/16-thread configuration is sufficient; the game rarely scales beyond 8 threads, so the 9700F's high clock speed matters more than additional cores.

The CPU's memory bandwidth of 89.6 GB/s via dual-channel DDR5 is adequate for feeding the sim's asset streaming. Microsoft Flight Simulator loads terrain and airport data continuously, and the memory subsystem must keep up with the CPU's simulation state. The 32 MB L3 cache helps with frequently accessed data, reducing the need for slower memory fetches. The processor's PassMark data compression score of 421,988 and integer math score of 120,788 indicate strong throughput for the background tasks the sim runs when loading new scenery regions.

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

The NVIDIA GeForce RTX 4070 uses the AD104 chip on TSMC's 5 nm process, with a base clock of 1920 MHz and a boost clock of 2475 MHz. It has 12 GB of GDDR6X memory on a 192-bit bus, yielding 504.2 GB/s bandwidth. The GPU includes 5,888 shading units, 184 TMUs, 64 ROPs, 46 RT cores, and 184 tensor cores. This hardware supports DirectX 12 Ultimate, Vulkan 1.4, and OpenGL 4.6, covering all the rendering APIs Microsoft Flight Simulator can use.

The RTX 4070's 12 GB VRAM is a key factor for this sim. Microsoft Flight Simulator streams high-resolution textures for terrain, aircraft, and weather effects. At 4K with High settings, the sim fits within 12 GB, as shown by the measured 57 FPS average. The GPU's 504.2 GB/s bandwidth ensures that texture streaming does not cause hitches when flying over dense urban areas or detailed airports. The boost clock of 2475 MHz provides the raw compute headroom needed for the sim's complex shaders, which handle lighting, clouds, and water reflections. The pixel rate of 158.4 GPixel/s and texture rate of 455.4 GTexel/s are adequate for 4K, though the data indicates that Ultra settings at that resolution strain the GPU.

In the PassMark G3D benchmark, the RTX 4070 scores 26,927, placing it at the 81st percentile among all GPUs. Its closest rivals are the NVIDIA Tesla P4 (37,628, 0.1% higher), AMD Radeon RX Vega 56 (37,507, 0.4% higher), NVIDIA GeForce RTX 4080 Mobile (38,135, 1.3% lower), and AMD Radeon PRO W6400 (37,157, 1.3% higher). These are synthetic scores; in Microsoft Flight Simulator, the GPU's performance is more dependent on memory bandwidth and VRAM capacity than raw compute, since the sim is known for its heavy texture streaming. The 12 GB VRAM is sufficient for 4K High but becomes the limiting factor at Ultra, where the measured FPS drops to 55.

The GPU's 21 Gbps effective memory speed is notable for this sim. Flight simulators benefit from fast VRAM because they continuously load new terrain tiles as the aircraft moves. The RTX 4070's memory subsystem, combined with its 64 ROPs, delivers consistent frame pacing in the measured data—the 4K Medium preset shows a minimum of 65 FPS and a maximum of 88 FPS, indicating no major stutters. The GPU's dual-slot cooler and 200 W TDP are standard for its class, and its PCIe 4.0 x16 interface is ample for the data transfer rates required.

How This Combo Ranks — use comboRankInGame vs other tested combos

This specific combination of the AMD Ryzen 7 9700F and NVIDIA GeForce RTX 4070 ranks 630th out of 2,996 tested combos in Microsoft Flight Simulator. That places it in the top 21% of all configurations tested, which is a strong result for a mid-range GPU paired with a recent 8-core CPU. The rank reflects the balance between CPU and GPU performance: the 9700F's high single-thread score (4,691) prevents it from bottlenecking the RTX 4070, while the GPU's 12 GB VRAM and 504.2 GB/s bandwidth handle the sim's rendering demands.

The 630th rank out of 2,996 combos means that more than 2,300 other configurations performed better, but those are likely to include higher-end GPUs like the RTX 4080 series or RTX 4090, or CPUs with higher multithread scores. The data shows that this combo is not at the top tier, but it is well above the median. For context, the rank is determined by average FPS across all tested resolutions and settings; the combo's 4K High result of 57 FPS and 1080p Ultra result of 92 FPS are solid, but not class-leading.

The rank also reflects the CPU's percentileVsAllCpus of 94 and the GPU's percentileVsAllGpus of 81. The CPU is a stronger performer relative to its peers than the GPU is, which means the RTX 4070 is more likely to be the limiting factor in this combo. This is evident in the FPS breakdown: at 1080p, the CPU keeps up with the GPU, but at 4K Ultra, the GPU's 55 FPS average shows it is hitting its compute and memory limits. The combo's rank of 630 suggests that a stronger GPU would yield more performance gains than a stronger CPU, given the same resolution and settings.

Measured FPS Breakdown — resolution by resolution, settings by settings, exact numbers

The measured FPS data provides a comprehensive view of this combo's performance across three resolutions and four settings presets. Here is the exact breakdown:

1920x1080 (1080p):

• Low: 165 FPS average
• Medium: 128 FPS average, with a minimum of 109 FPS and maximum of 147 FPS
• High: 96 FPS average
• Ultra: 92 FPS average

2560x1440 (1440p):

• Low: 133 FPS average
• Medium: 103 FPS average, with a minimum of 88 FPS and maximum of 119 FPS
• High: 78 FPS average
• Ultra: 74 FPS average

3840x2160 (4K):

• Low: 98 FPS average
• Medium: 76 FPS average, with a minimum of 65 FPS and maximum of 88 FPS
• High: 57 FPS average
• Ultra: 55 FPS average

At 1080p, the combo is clearly CPU-bound. The difference between Low (165 FPS) and Ultra (92 FPS) is 73 FPS, which indicates that the GPU's load increases significantly with settings, but the CPU can feed it enough frames to maintain high numbers. The 1080p Medium preset shows a tight range (109 to 147 FPS), suggesting consistent frame pacing without major drops. At 1080p Ultra, the 92 FPS average is still very playable for a flight sim, where smoothness matters more than raw frame rate.

Moving to 1440p, the FPS drops are more pronounced. Low settings yield 133 FPS, Medium 103 FPS, High 78 FPS, and Ultra 74 FPS. The gap between Low and Ultra is 59 FPS, which is slightly smaller than at 1080p (73 FPS). This indicates that the GPU is becoming more of a bottleneck as resolution increases. The 1440p Medium preset has a minimum of 88 FPS, which is still well above the 60 FPS threshold for smooth flight sim gameplay.

At 4K, the GPU is clearly the limiting factor. Low settings produce 98 FPS, which is remarkable for a flight sim at 4K, but Ultra drops to 55 FPS. The 4K High preset at 57 FPS is right at the edge of smooth playability—it is playable, but not ideal for fast-moving flight over complex scenery. The 4K Medium preset shows a minimum of 65 FPS, which is acceptable, but the Ultra preset's 55 FPS average suggests that some users may want to lower settings or use upscaling if they own a 4K display.

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

The FPS scaling across resolutions reveals a classic GPU-bound pattern. At High settings, the average FPS drops from 96 at 1080p to 78 at 1440p (an 18.8% drop), then to 57 at 4K (a 40.6% drop from 1440p). This is a steeper decline than a purely CPU-bound scenario would show. At Low settings, the FPS drops from 165 at 1080p to 133 at 1440p (a 19.4% drop), then to 98 at 4K (a 26.3% drop from 1440p). The Low settings show a more gradual decline, indicating that the CPU is still capable of feeding the GPU at lower resolutions.

The key takeaway is that the RTX 4070's performance scales predictably with resolution, but the CPU's contribution becomes less relevant as resolution increases. At 1080p, the CPU's high single-thread score (4,691) allows the GPU to reach 165 FPS on Low settings. At 4K, the GPU's 12 GB VRAM and 504.2 GB/s bandwidth are the primary constraints. The 4K Ultra result of 55 FPS versus the 4K High result of 57 FPS (a 2 FPS difference) shows that the GPU is already near its compute limit at 4K High, and Ultra settings add little additional strain.

The data also shows that the combo is not CPU-limited at 4K, because the FPS at 4K Low (98) is still much higher than the 4K Ultra (55). If the CPU were the bottleneck, the FPS would be similar across settings at the same resolution. Instead, the 43 FPS gap between Low and Ultra at 4K confirms that the GPU is the limiting component. At 1080p, the gap between Low (165) and Ultra (92) is 73 FPS, which is larger, but that is because the GPU is less stressed at lower resolutions, allowing the CPU to drive higher frame rates. In contrast, at 4K, the GPU reaches its ceiling quickly, and the CPU has headroom to spare.

This analysis suggests that for 1080p and 1440p gaming, the Ryzen 7 9700F is a good match for the RTX 4070, as neither component is severely bottlenecked. For 4K, the GPU is the clear limiting factor, and users who prioritize 4K Ultra should consider a higher-tier GPU. However, the 4K Medium result of 76 FPS shows that this combo can handle 4K with moderate settings, making it a viable option for flight sim enthusiasts with 4K displays who are willing to adjust settings.
