Microsoft Flight Simulator

Microsoft Flight Simulator is notoriously demanding, and the data for this AMD Ryzen 5 8400F and NVIDIA GeForce RTX 4070 Ti SUPER configuration shows a system that can handle it with authority across the board. The measured results indicate a pairing that scales predictably with resolution and settings, making it a versatile option for virtual pilots. This analysis breaks down the performance metrics, focusing on where the CPU and GPU each flex their muscles and what the numbers mean for your flight plan.

Resolution Scaling

The frame rate progression from 1080p to 4K reveals a classic shift in system bottleneck. At 1920x1080 with Low settings, the rig pushes an average of 194 FPS. Moving to 2560x1440 at the same Low preset, that figure drops to 157 FPS, and at 3840x2160 it falls further to 116 FPS. This steep decline—a 40% reduction from 1080p to 4K on Low—shows that even at the lowest visual load, the GPU is being tasked harder as pixel count rises. The CPU is clearly capable of feeding frames at lower resolutions, as evidenced by the very high 194 FPS mark, but the GPU begins to feel the pressure sooner.

When we switch to the High preset, the scaling pattern shifts. The average FPS goes from 114 at 1080p, to 92 at 1440p, and finally to 68 at 4K. The relative drop from 1080p to 1440p is about 19%, and from 1440p to 4K it's another 26%. This indicates that at High settings, the load is more balanced, but the GPU is still the primary limiter as resolution increases. The system is not CPU-bound at High settings, as the 1080p score of 114 FPS is still high enough to suggest headroom, but the GPU's workload is scaling significantly with each resolution step.

The Medium preset data tells a similar story with a tighter range. The average FPS at 1080p is 151, dropping to 122 at 1440p, and then to 90 at 4K. This represents a 20% and 26% drop for each successive resolution jump, respectively. The presence of min FPS data for Medium settings—129 at 1080p, 104 at 1440p, and 77 at 4K—provides a useful look at frame time consistency. The gap between average and minimum FPS widens as resolution increases, from 22 FPS at 1080p to 13 FPS at 4K, suggesting that the GPU is not only producing lower averages but also experiencing more variance in complex scenes at higher resolutions.

At Ultra settings, the highest visual fidelity, the system still manages playable frame rates. The average FPS is 108 at 1080p, 87 at 1440p, and 64 at 4K. The performance hit from 1080p to 4K is approximately 41%, which is substantial but expected for a flight simulator with heavy draw distances. The 4K Ultra result of 64 FPS is particularly telling; it is the lowest average recorded in the entire dataset, highlighting that this is the most demanding configuration tested. Overall, the data shows that the 4070 Ti SUPER is the scaling bottleneck, with its workload increasing predictably as resolution climbs, while the CPU maintains a strong foundation.

CPU Role

The AMD Ryzen 5 8400F is a 6-core, 12-thread processor based on the Zen 4 architecture, running on the AM5 socket. Its base clock is 4.20 GHz with a boost clock of 4.70 GHz. In synthetic benchmarks, it scores 20,851 in Cinebench R23 multi-core and 2,943 in single-core. This places it in the 77th percentile among all CPUs, with an average benchmark score of 25,005. Its nearest rival, the AMD Ryzen 5 7500F, scores 24,964, a delta of just 0.2%, indicating near-identical multi-threaded performance. The data suggests that the 8400F is more than sufficient to drive the RTX 4070 Ti SUPER in this game.

The CPU's role in Microsoft Flight Simulator is to handle the complex simulation logic, physics, and AI traffic, which often rely on single-thread performance. The single-core score of 2,943 in Cinebench R23 is robust, and the 3dmark single-thread score of 951 reinforces this. Looking at the frame rates, the 1080p Low result of 194 FPS is a clear sign that the CPU is not a limiting factor at lower resolutions. Even at 1080p Ultra, the 108 FPS average suggests the CPU can keep up with the GPU's output. The 8400F's 16 MB of shared L3 cache and dual-channel DDR5 memory support provide a solid platform for the game's data streaming needs.

The benchmark data indicates that the CPU's performance is consistent with its rivals, but it doesn't need to be exceptional to satisfy this game. The 0.2% delta with the Ryzen 5 7500F shows they are effectively interchangeable in performance. The 8400F's 12 threads are adequate, as the game rarely scales perfectly with core counts. The key takeaway is that the CPU provides a stable, high-frequency foundation that allows the GPU to become the star of the show when settings and resolution are increased. The CPU's 65 W TDP also suggests it runs efficiently, leaving thermal headroom for sustained performance during long flights.

GPU Role

The NVIDIA GeForce RTX 4070 Ti SUPER is a powerhouse built on the Ada Lovelace architecture with 16 GB of GDDR6X memory on a 256-bit bus, yielding a bandwidth of 672.3 GB/s. Its boost clock is 2610 MHz, and it has 8448 shading units. It scores 31,811 in the Passmark G3D test and sits in the 76th percentile among all GPUs, with an average benchmark score of 31,087. Its nearest rival, the NVIDIA TITAN RTX, scores 31,676, a delta of -1.9%, showing the 4070 Ti SUPER is slightly behind that older flagship in raw compute but benefits from newer architecture and more VRAM.

In Microsoft Flight Simulator, the GPU role is primarily about rendering the vast landscapes, detailed aircraft models, and lighting effects. The 16 GB VRAM is a significant asset, as this game can consume large amounts of memory at high resolutions and with high texture quality. The data shows the GPU is the main scaling factor. At 1080p Low, the 194 FPS average shows the GPU is not heavily taxed, but as resolution and settings increase, the GPU's workload rises proportionally. The 4K Ultra result of 64 FPS is the GPU's most strenuous test, and it passes, but with less headroom.

The GPU's performance relative to its rivals is interesting. While it scores lower than the TITAN RTX in the Passmark G3D test, its performance in this game is strong. The 4070 Ti SUPER's architecture supports DirectX 12 Ultimate, which the game can leverage. The 44.10 TFLOPS of FP32 compute power is ample for the game's shader complexity. The data indicates that the GPU is the primary component affecting frame rate changes across the measured presets. For instance, the jump from Low to Ultra at 1440p results in a 44% drop in average FPS, from 157 to 87. This is a clear sign that the GPU is doing the heavy lifting and that its performance scales with the graphical demands placed upon it.
