# Microsoft Flight Simulator: AMD Ryzen 5 7400F + NVIDIA GeForce RTX 3080 Analysis

This combination of AMD's Ryzen 5 7400F processor and NVIDIA's GeForce RTX 3080 graphics card delivers a mid-pack performance profile in Microsoft Flight Simulator, ranking 786th out of 2,996 tested combinations. That places this pairing comfortably in the upper quartile of all tested systems, suggesting a balanced platform that can handle the simulator's demanding rendering workload, though it is not among the elite performers. The data reveals a system that scales predictably across resolutions and settings, with the RTX 3080 emerging as the primary driver of frame rates while the six-core Zen 4 processor provides a solid foundation without becoming a bottleneck at most configurations.

How This Combo Ranks

The combo rank of 786 out of 2,996 tested configurations places this system in the 74th percentile overall, indicating that roughly three-quarters of tested combinations deliver lower performance in Microsoft Flight Simulator. This is a strong showing for a pairing that combines a mid-range 2025 processor with a 2020 flagship GPU. The rank reflects the synergy between the two components; neither is the absolute fastest in its class, but together they produce consistently playable frame rates across all tested scenarios.

Breaking down the individual components, the CPU's percentile versus all processors is 83, meaning the Ryzen 5 7400F outperforms 83% of all CPUs in the database's aggregate benchmarks. Its average benchmark score of 32,750 is remarkably close to its nearest rivals; the Intel Core i5-14600T scores 32,707 (a 0.1% delta), the Intel Core Ultra 7 155H scores 32,697 (0.2% delta), and the AMD Ryzen 7 PRO 6850H scores 32,812 (a -0.2% delta, meaning the 7400F is slightly behind). This clustering shows that in raw computational throughput, the 7400F is essentially interchangeable with these competitors, differing by less than a third of a percent.

The GPU's percentile versus all graphics cards is 68, with an average benchmark score of 23,172. Its nearest rivals are intriguingly diverse: the NVIDIA P106-100 (23,249, -0.3% delta), AMD Radeon Pro Vega 16 (23,250, -0.3% delta), AMD Radeon RX 6600M (23,273, -0.4% delta), and AMD Radeon R9 M290X (23,276, -0.4% delta). The RTX 3080 sits slightly below all four in aggregate scores, though the deltas are minuscule. This suggests that in synthetic benchmarks, the 3080 is statistically tied with these very different cards, but in this flight simulator, its real-world performance is what matters.

The composite rank of 786 is better than either component's individual percentile might suggest on its own, indicating that this specific pairing is well-matched for Microsoft Flight Simulator's workload. The data implies that the combination extracts more performance from the hardware than the sum of its parts would predict.

CPU Role

The AMD Ryzen 5 7400F is a six-core, twelve-thread processor built on the Zen 4 architecture with a 5 nm process node. It operates at a base clock of 3.70 GHz and boosts to 4.70 GHz, with a 65 W TDP. The cache hierarchy includes 64 KB of L1 per core, 1 MB of L2 per core, and 32 MB of shared L3 cache. This configuration represents a modern, efficient design that pairs well with the simulator's need for consistent single-thread performance.

In Microsoft Flight Simulator, the CPU's role is primarily to manage the simulation logic, physics calculations, and asset streaming. The 7400F's single-thread performance is strong, as evidenced by its Cinebench R23 single-core score of 3,072 and PassMark single-thread score of 3,689. These numbers indicate that the processor can handle the simulator's heavy single-threaded workloads without becoming the limiting factor. The multi-threaded scores — Cinebench R23 multi-core at 21,765, Cinebench R20 multi-core at 9,141, and PassMark multi-thread at 25,645 — show that the processor also has ample headroom for background tasks and the simulator's multi-threaded components.

The 7400F's 83rd percentile ranking among all CPUs, combined with its average benchmark score of 32,750, places it in a tightly contested performance tier. The delta of just 0.1% versus the Intel Core i5-14600T and 0.2% versus the Intel Core Ultra 7 155H means that swapping between these processors would produce virtually identical results in this game. The AMD Ryzen 7 PRO 6850H is marginally ahead at -0.2% delta, while the AMD Ryzen AI 7 PRO 360 trails by 0.3%. This suggests that CPU choice within this performance band has minimal impact on the final frame rates.

The processor's 32 MB of shared L3 cache is particularly relevant for flight simulation, where terrain data and object information are frequently accessed. The dual-channel DDR5 memory support with 83.2 GB/s bandwidth provides sufficient data throughput for the simulator's streaming requirements. The 7400F supports PCIe Gen 5 with 24 lanes, though the RTX 3080 uses PCIe 4.0 x16, which is fully compatible and does not bottleneck the GPU.

GPU Role

The NVIDIA GeForce RTX 3080 is built on the Ampere architecture using Samsung's 8 nm process, with a chip designated GA102 containing 28,300 million transistors on a 628 mm² die. It operates at a base clock of 1440 MHz and boosts to 1710 MHz, with memory clocked at 1188 MHz (19 Gbps effective). The GPU features 8,704 shading units, 272 texture mapping units, 96 raster output units, 68 ray tracing cores, and 272 tensor cores. Its compute capabilities include 29.77 TFLOPS for both FP32 and FP16, with pixel rate of 164.2 GPixel/s and texture rate of 465.1 GTexel/s.

The 10 GB of GDDR6X memory on a 320-bit bus provides 760.3 GB/s of bandwidth, which is crucial for Microsoft Flight Simulator's high-resolution texture streaming. The simulator renders vast landscapes, detailed aircraft models, and dynamic weather systems, all of which place significant demands on GPU memory and bandwidth. The 3080's substantial memory bandwidth ensures that texture loads do not cause stuttering, even at 4K resolution.

The RTX 3080's performance in this game is moderated by its 68th percentile ranking among all GPUs, with an average benchmark score of 23,172. The nearest rival comparisons are unusual; the NVIDIA P106-100, AMD Radeon Pro Vega 16, AMD Radeon RX 6600M, and AMD Radeon R9 M290X all score within 0.4% of the 3080 in aggregate benchmarks. However, these synthetic scores do not fully capture the 3080's capabilities in a demanding title like Flight Simulator, where its ray tracing cores and tensor cores may provide advantages that aggregate benchmarks do not measure.

The GPU's 10 GB VRAM is sufficient for the tested settings, as evidenced by the measured frame rates. At no point does the simulator appear to be VRAM-limited; the performance scales consistently with resolution and settings, suggesting the 3080 has adequate memory headroom. The dual-slot design and 320 W TDP indicate a power-hungry card, though the 700 W suggested PSU provides adequate headroom for this pairing.

Measured FPS Breakdown

At 1080p, the RTX 3080 delivers excellent performance across all settings. Low settings produce an average of 158 FPS, which is extraordinarily high for a flight simulator and suggests the CPU is not limiting at this configuration. Medium settings yield 123 FPS with a minimum of 104 FPS and maximum of 141 FPS, showing consistent frame delivery. High settings drop to 92 FPS average, while Ultra settings produce 88 FPS. The gap between High and Ultra at 1080p is minimal (4 FPS), indicating that the Ultra preset's additional visual features have diminishing performance costs at this resolution.

At 1440p, the frame rates remain strong but show the expected scaling. Low settings reach 127 FPS, Medium delivers 99 FPS with a minimum of 84 FPS and maximum of 114 FPS, High produces 74 FPS, and Ultra drops to 71 FPS. The High-to-Ultra gap narrows further to just 3 FPS at this resolution, suggesting that the GPU is beginning to become the primary bottleneck. The difference between Low and Ultra at 1440p is 56 FPS, representing a 44% reduction in frame rate when enabling maximum visual quality.

At 4K, the performance profile shifts decisively toward GPU-bound behavior. Low settings still deliver a playable 94 FPS, while Medium produces 73 FPS with a minimum of 62 FPS and maximum of 84 FPS. High settings drop to 55 FPS, and Ultra settings fall to 52 FPS. The High-to-Ultra gap remains small at 3 FPS, but the overall range from Low to Ultra is 42 FPS, representing a 45% reduction. The minimum FPS of 62 at Medium settings indicates that even at 4K, the system maintains playable frame rates without severe dips.

The data shows that this combination delivers its best experience at 1440p with High or Ultra settings, where frame rates remain above 70 FPS while retaining visual quality. At 1080p, all settings are playable, with even Ultra exceeding 88 FPS. At 4K, the system is best suited to Medium or Low settings for smooth gameplay, though High remains marginally playable at 55 FPS.

Resolution Scaling

The performance scaling from 1080p to 4K reveals important insights about which component is limiting performance at various configurations. At Low settings, the frame rate drops from 158 FPS at 1080p to 127 FPS at 1440p to 94 FPS at 4K. This represents a 41% reduction from 1080p to 4K, which is less than the pixel-count increase of 400%. This sub-linear scaling indicates that at Low settings, the CPU or another system component is partially limiting performance, preventing the GPU from fully utilizing its capabilities at lower resolutions.

At Medium settings, the progression is 123 FPS at 1080p, 99 FPS at 1440p, and 73 FPS at 4K. The reduction from 1080p to 4K is also 41%, mirroring the Low setting behavior. The minimum FPS values at Medium settings — 104 at 1080p, 84 at 1440p, and 62 at 4K — show consistent scaling, with each resolution step reducing the minimum by approximately 20 FPS.

At High settings, the frame rates are 92 FPS at 1080p, 74 FPS at 1440p, and 55 FPS at 4K. This represents a 40% reduction from 1080p to 4K, nearly identical to the Low and Medium scaling. At Ultra settings, the progression is 88 FPS at 1080p, 71 FPS at 1440p, and 52 FPS at 4K, again showing a 41% reduction.

The uniformity of the scaling across all settings — consistently around 40-41% reduction from 1080p to 4K — suggests that the system is balanced, with neither the CPU nor GPU creating a disproportionate bottleneck at any resolution. However, the relatively modest scaling compared to the 4x pixel increase indicates that the CPU does exert some influence on performance even at 4K. If the GPU were the sole bottleneck, the frame rate would drop more steeply with resolution. The fact that the reduction is consistent across settings suggests that the Ryzen 5 7400F's six cores provide adequate simulation throughput, while the RTX 3080's rendering capabilities scale predictably with resolution.

Settings Recommendations

For the best overall experience, Medium settings at 1440p provide an excellent balance of visual fidelity and performance. The measured 99 FPS average with an 84 FPS minimum ensures smooth gameplay even in complex scenes with dense terrain or weather effects. The 114 FPS maximum shows that the system has headroom for less demanding moments, such as high-altitude cruising or simple airfields. This configuration delivers frame rates that are 82% higher than the 4K Ultra setting while maintaining good visual quality.

For players prioritizing smoothness over visuals, Low settings at 1080p deliver an exceptional 158 FPS average, which is far beyond what flight simulation typically requires. Even at 4K, Low settings maintain 94 FPS, making this the best choice for a high-resolution experience without performance compromises. The Low preset at 4K provides a 71% frame rate improvement over Ultra at the same resolution, at the cost of reduced detail density and visual effects.

High settings at 1440p (74 FPS) represent the sweet spot for players who want near-maximum visual quality without sacrificing playability. The difference between High and Ultra at 1440p is only 3 FPS, suggesting that the Ultra preset's additional effects are relatively inexpensive at this resolution. However, the High preset at 4K (55 FPS) is borderline playable, making Medium at 4K (73 FPS) a safer choice for 4K displays.

Ultra settings are best reserved for 1080p, where the system maintains 88 FPS average. At 1440p, Ultra's 71 FPS is still playable, but the 3 FPS gain over High makes the Ultra preset a questionable choice given its additional visual effects. At 4K, Ultra's 52 FPS is marginally playable but may cause noticeable stuttering in dense environments, making Medium or High the recommended settings for 4K users. The data consistently shows that this system delivers the best experience at 1440p with High or Medium settings, with 1080p Ultra as a strong alternative for maximum visual quality.
