Microsoft Flight Simulator

Microsoft Flight Simulator is one of the most demanding titles in the database, and the Intel Core i5-12400 + AMD Radeon RX 7900 XT combination delivers a performance profile that is heavily dictated by resolution and settings. The data indicates a pairing that is capable of high refresh rates at 1080p but transitions into a strictly 60 FPS-oriented experience at 4K, with the CPU acting as a significant anchor in lower resolutions.

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

The Intel Core i5-12400 provides 6 cores and 12 threads, operating at a base clock of 2.50 GHz and a boost clock of 4.40 GHz. This Alder Lake-S architecture chip, built on a 10 nm process, has a 65 W TDP and supports DDR4 and DDR5 memory through a dual-channel interface. In synthetic benchmarks, the processor scores 15,935 in Cinebench R23 multi-core and 2,249 in single-core, placing it in the 77th percentile among all CPUs. Its average benchmark score of 19,850 puts it in a tight race with the Intel Core i7-9700, which it edges out by 0.1%, and the Intel Core i7-8700, which it trails by 0.2%. This shows the i5-12400 has enough thread throughput for the simulation’s background tasks, but its single-core performance is what drives the flight model and physics calculations.

In Microsoft Flight Simulator, the CPU’s role becomes evident when examining the frame rate scaling from 1080p to 4K. At 1080p with Low settings, the combo produces 177.6 FPS, which is a clear indication that the graphics card is not the limiting factor at this resolution. However, as settings increase to Ultra at 1080p, the frame rate drops to 98.3 FPS, a reduction of 44.6% that is largely attributable to increased CPU overhead from draw calls and AI traffic simulation. The processor’s 18 MB of shared L3 cache and 1.25 MB per-core L2 cache are sufficient for the game’s data streaming, but the architecture does not provide the headroom needed to maintain peak frame rates when the GPU is underutilized. The benchmark results suggest that the i5-12400 is a balanced mid-range option that allows the GPU to stretch its legs at lower resolutions, but it cannot fully saturate the RX 7900 XT at 1080p with high refresh rate targets.

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

The AMD Radeon RX 7900 XT is a high-end RDNA 3.0 graphics card with 20 GB of GDDR6 memory on a 320-bit bus, delivering 800.0 GB/s of bandwidth. Its boost clock reaches 2394 MHz, with a game clock of 2025 MHz, and it features 5,376 shading units and 192 ROPs. In the Passmark G3D benchmark, it scores 29,009, placing it in the 82nd percentile among all GPUs. Its average benchmark score of 38,358 is virtually identical to the NVIDIA GeForce RTX 5080 Mobile, which it matches with a 0.0% delta, and it sits 0.6% ahead of the RTX 4080 Mobile. This positions the card as a strong 4K-capable solution on paper, but the measured FPS in this simulation tells a more nuanced story.

The GPU’s 20 GB VRAM is never a bottleneck in this title, even at 4K Ultra, where the frame rate settles at 54.9 FPS. The limiting factor is raw compute throughput, as the card’s 51.48 TFLOPS FP32 performance is heavily taxed by the game’s complex terrain rendering and weather effects. At 1440p High, the combo achieves 84.2 FPS, which is a 74.4% increase over 4K High’s 58.2 FPS, demonstrating that the GPU has substantial headroom when pixel count is reduced. The card’s memory bandwidth of 800.0 GB/s ensures texture streaming is smooth, but the data suggests that the RX 7900 XT is capable of exceeding 100 FPS only when paired with lower settings and resolutions, as seen in the 1080p Medium result of 137.1 FPS. The GPU’s performance is consistent with its theoretical specs, but the simulation’s engine places a premium on both geometry and pixel shading, which the card handles with decreasing efficiency as resolution climbs.

Settings Recommendations — which preset gives the best experience per the measured rows

The measured data suggests that the Ultra preset is not viable for smooth gameplay at 4K, as it averages 54.9 FPS, which falls below the 60 FPS threshold. At 4K, the High preset provides 58.2 FPS, still marginally below 60 FPS, making Medium the best choice for 4K, with an average of 82.1 FPS. This represents a 49.5% improvement over Ultra and ensures a fluid experience without sacrificing too much visual fidelity. At 1440p, the High preset delivers 84.2 FPS, which is a comfortable margin above 60 FPS and preferable to Medium’s 109.5 FPS if visual quality is prioritized; however, for competitive or high-refresh displays, Medium is the sweet spot. At 1080p, the High preset at 103.9 FPS is the most balanced option, as it provides a triple-digit frame rate while retaining better shadows and textures than Medium’s 137.1 FPS. The Ultra preset at 1080p yields 98.3 FPS, which is still playable but offers diminishing returns over High. The data indicates that the Low preset is only necessary for extreme frame rate targets, such as 177.6 FPS at 1080p, which is 71.0% higher than High but at a significant visual cost. For most users, Medium at 4K and High at 1440p/1080p represent the optimal balance of performance and image quality.

How This Combo Ranks — use comboRankInGame vs other tested combos

This specific CPU-GPU combination ranks 383rd out of 1,795 tested combos in Microsoft Flight Simulator, placing it in the top 21.3% of all configurations. The rank reflects a pairing that is above average but not elite, which aligns with the component’s individual percentiles: the CPU sits in the 77th percentile and the GPU in the 82nd percentile. The rank suggests that while the RX 7900 XT is a high-tier GPU, the i5-12400 holds the combo back from reaching the upper echelons of the leaderboard. The data shows that combos with stronger CPUs achieve higher ranks at 1080p, where the GPU is not the bottleneck, but at 4K, the combo’s rank likely improves relative to others, as the GPU becomes the dominant factor. The 383rd position indicates that this is a solid mid-to-high-tier setup, but users seeking top-tier performance in this simulation would need a more powerful processor to better complement the GPU’s capabilities.

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

The frame rate scaling across resolutions reveals a classic CPU-bound-to-GPU-bound transition. At Low settings, the combo drops from 177.6 FPS at 1080p to 138.6 FPS at 1440p, a 22.0% reduction, and then to 100.6 FPS at 4K, a further 27.4% reduction from 1440p. This indicates that even at Low settings, the GPU is increasingly taxed as resolution rises, but the CPU still has headroom, as the 4K Low result of 100.6 FPS is higher than the 4K High result of 58.2 FPS. At High settings, the drop from 1080p to 1440p is 19.0% (from 103.9 to 84.2 FPS), and from 1440p to 4K is 30.9% (from 84.2 to 58.2 FPS). This larger percentage drop at higher resolutions confirms that the GPU is the primary limiter at 4K, as the pixel throughput demand scales super-linearly with resolution. Conversely, the relatively modest drop from 1080p to 1440p at High settings (19.0%) compared to the drop from 1440p to 4K (30.9%) suggests that the CPU is still contributing to the bottleneck at 1440p, whereas at 4K, the GPU is fully saturated. The Ultra preset shows a similar pattern, with 98.3 FPS at 1080p, 82.2 FPS at 1440p, and 54.9 FPS at 4K, representing a 16.4% and 33.2% drop respectively. The data clearly indicates that the CPU limits performance at 1080p, while the GPU becomes the sole limiting component at 4K, making the combo more balanced at 1440p where both components are moderately stressed.
