Microsoft Flight Simulator

# Microsoft Flight Simulator: Intel Core i5-12400F + AMD Radeon RX 7900 XT

This combination pairs a 6-core, 12-thread Alder Lake processor with a flagship RDNA 3 graphics card, producing a system that handles Microsoft Flight Simulator with distinct performance tiers depending on resolution and preset. The measured data reveals a setup where the GPU dominates at higher resolutions, while the CPU's single-thread capabilities become increasingly relevant as resolution drops. The combo ranks 342nd out of 1795 tested configurations, placing it in the top 19% of all pairings.

Resolution Scaling

The FPS drop from 1080p to 4K is steep but predictable, with the scaling pattern exposing the GPU as the primary limiter at higher resolutions. At Low settings, performance falls from 176.7 FPS at 1920x1080 to 143.1 FPS at 2560x1440, then to 100.9 FPS at 3840x2160—a cumulative reduction of 75.8 FPS from 1080p to 4K. This represents a 42.9% performance loss, which is substantial but not catastrophic, indicating the RX 7900 XT's 800.0 GB/s memory bandwidth and 51.48 TFLOPS FP32 compute are being progressively taxed.

The Ultra preset shows a similar but slightly steeper curve: 98.4 FPS at 1080p, 77.3 FPS at 1440p, and 59.6 FPS at 4K. The 4K Ultra result barely crosses the 60 FPS threshold, while 1440p Ultra delivers a comfortable margin above it. Interestingly, the gap between 1080p and 1440p at Ultra (21.1 FPS) is nearly identical to the gap between 1440p and 4K (17.7 FPS), suggesting consistent scaling behavior across the resolution spectrum.

The Medium preset tells a similar story with higher absolute numbers: 140.9 FPS at 1080p, 110.9 FPS at 1440p, and 79.2 FPS at 4K. The 4K Medium result is nearly 20 FPS higher than 4K Ultra, making it a viable option for users prioritizing frame rate over visual fidelity. The High preset sits between Medium and Ultra, with 106.2 FPS at 1080p, 83.5 FPS at 1440p, and 60.2 FPS at 4K.

What the scaling reveals is that the RX 7900 XT is the bottleneck at 4K across all settings, as evidenced by the 59.6–100.9 FPS range. At 1080p, however, the CPU begins to assert itself—the 176.7 FPS Low result suggests the i5-12400F's 4.40 GHz boost clock is sufficient to feed the GPU, but the relatively modest 909 single-thread score in 3DMark indicates headroom is limited. The data shows diminishing returns on FPS gains as resolution drops below 1440p, particularly at Low settings where the 143.1 FPS at 1440p jumps only 33.6 FPS to 176.7 FPS at 1080p.

CPU Role

The Intel Core i5-12400F brings 6 cores and 12 threads, with a base clock of 2.50 GHz and a boost clock of 4.40 GHz. Its 18 MB shared L3 cache and 80 KB L1 cache per core provide the memory hierarchy needed for flight simulation's complex world-streaming workloads. The CPU's 3DMark single-thread score of 909 and multi-thread score of 5912 at max threads indicate balanced performance that suits a game like Microsoft Flight Simulator, which depends heavily on single-thread performance for physics and AI calculations.

The CPU's benchmark profile shows strong scaling from 2 threads (1699) to 4 threads (3067), then to 8 threads (4779), and finally to 16 threads (5895) and max threads (5912). This near-flat performance beyond 8 threads reveals that the i5-12400F has limited headroom for heavily threaded workloads, but flight simulation rarely utilizes more than a few cores effectively. The Cinebench R23 multicore score of 16518 and single-core score of 2332 reinforce this interpretation—the single-core result is competitive, while the multicore figure reflects the 6-core design.

The CPU's PassMark multithread score of 19433 and single-thread score of 3481 place it in the 77th percentile of all CPUs. Compared to its nearest rivals, the i5-12400F's average benchmark score of 19221 is essentially tied with the Intel Core i7-8700K (19210, deltaPct 0.1%) and Intel Core i5-1335U (19167, deltaPct 0.3%), while slightly trailing the AMD Ryzen 5 7533HS (19364, deltaPct -0.7%) and leading the AMD EPYC 7773X (18979, deltaPct 1.3%). This clustering indicates that the i5-12400F delivers performance squarely in the mainstream desktop range.

In the context of Microsoft Flight Simulator, the CPU's role becomes evident when comparing 1080p Low (176.7 FPS) to 4K Low (100.9 FPS). The 75.8 FPS difference at Low settings—where GPU load is minimized—suggests the CPU is not the limiting factor even at 1080p. However, the 65W TDP and locked multiplier mean there is no overclocking headroom, so the 4.40 GHz boost clock represents the ceiling for this processor.

The data indicates that this combo is well-balanced for 1440p gaming, where both components contribute meaningfully to the final frame rate.

Settings Recommendations

For 4K displays, the data shows that High settings (60.2 FPS) are the safest choice for maintaining a playable frame rate, while Ultra (59.6 FPS) dips just below the 60 FPS threshold. Medium at 4K (79.2 FPS) provides a substantial frame rate buffer and is recommended for users who prioritize smoothness over maximum visual quality. Low at 4K (100.9 FPS) is viable for competitive or high-refresh-rate scenarios, though it sacrifices the visual fidelity that flight simulation enthusiasts typically seek.

For 1440p monitors, Ultra settings (77.3 FPS) deliver a fully playable experience with maximum visual quality. High (83.5 FPS) adds a modest frame rate cushion, while Medium (110.9 FPS) and Low (143.1 FPS) offer options for higher refresh rates. The 1440p Ultra result is particularly noteworthy—it provides the best balance of visual fidelity and performance in the entire dataset.

For 1080p, all settings are playable, but the recommendation depends on monitor refresh rate. Ultra (98.4 FPS) is suitable for 60 Hz and 100 Hz displays, while High (106.2 FPS) and Medium (140.9 FPS) support 120 Hz panels. Low (176.7 FPS) is the only preset that approaches 144 Hz territory, though the visual compromise may not be worth it for most flight simulation users.

The optimal preset across all resolutions is Medium at 1440p, delivering 110.9 FPS with a comfortable margin above 60 FPS and visual quality that retains the core flight simulation experience. For users with 4K displays, High at 4K (60.2 FPS) is the recommended compromise, as it crosses the 60 FPS line while preserving most visual details. The Ultra preset at any resolution offers the highest fidelity but requires accepting frame rates at or near the 60 FPS floor.
