Resolution Scaling

The measured FPS data for Microsoft Flight Simulator with the Intel Core i5-12400F and Intel Arc B580 reveals a clear pattern: this combo is heavily GPU-bound at higher resolutions. From 1080p to 1440p, the average FPS across all settings drops by roughly 20-25%, and the climb to 4K costs another 30-35% on average. At 1080p Low, the combo delivers 96.4 FPS; at 1440p Low that falls to 76.9 FPS, and at 4K Low it reaches 56.4 FPS. This scaling curve is steep and consistent, indicating that the Arc B580's rendering throughput, not the CPU, is the limiting factor as pixel count rises.

The gap between 1080p and 4K is most pronounced at Low settings, where the frame rate drops from 96.4 to 56.4 FPS — a 41.5% reduction. At Ultra settings, the same resolution climb yields a smaller relative drop: from 52.5 FPS at 1080p to 31.7 FPS at 4K, a 39.6% decline. The fact that the Ultra preset at 1080p (52.5 FPS) is only slightly faster than the Low preset at 4K (56.4 FPS) underscores how much resolution dominates performance. The data suggests that users targeting 4K should expect playable but not smooth frame rates, while 1080p and 1440p remain viable for higher refresh rates at lower presets.

FAQ

Q: What is the best resolution for this CPU-GPU combo in Microsoft Flight Simulator?

A: Based on the measured FPS, 1440p offers the best balance. At High settings it delivers 45.2 FPS, and at Medium it reaches 59.4 FPS, which is smoother than 4K while still offering more detail than 1080p.

Q: Can this combo handle 4K Ultra settings?

A: No. At 4K Ultra, the average FPS is 31.7 FPS, which is below the 60 FPS threshold for smooth flight simulation. Even 4K High only reaches 31.5 FPS, so 4K is only playable at Low (56.4 FPS) or Medium (43 FPS).

Q: How much faster is 1080p compared to 1440p at the same settings?

A: At High settings, 1080p delivers 57.6 FPS versus 45.2 FPS at 1440p — a 27.4% advantage. At Low settings, the gap is 96.4 FPS versus 76.9 FPS, which is a 25.3% improvement.

Q: Is the CPU or GPU the bottleneck at 1080p?

A: The data shows the GPU is the primary limiter even at 1080p. The i5-12400F has a passmark single-thread score of 3481 and a multithread score of 19433, which are strong, yet the frame rates scale predictably with resolution — a sign the Arc B580 is maxed out before the CPU becomes a constraint.

Q: What settings preset gives the highest FPS at 1440p?

A: Low settings at 1440p produce 76.9 FPS, which is the highest measured at that resolution. Medium follows at 59.4 FPS, while High and Ultra drop to 45.2 and 41.3 FPS respectively.

Q: How does the Arc B580 compare to its nearest GPU rival in this game?

A: The Arc B580's average benchmark score is 23021, which is 0.7% lower than the GeForce RTX 4060 (23181) and 1.3% higher than the RTX 4060 Mobile (22729). This places it in the same performance class, though flight sim results will vary.

How This Combo Ranks

The Intel Core i5-12400F paired with the Intel Arc B580 ranks 1420 out of 1795 tested combos in Microsoft Flight Simulator. This places it in the bottom 21% of all tested configurations, which is a low position for a modern setup. The ranking reflects the demanding nature of the flight simulator and the GPU's mid-range positioning. For context, the i5-12400F itself has a percentile of 77 against all CPUs, meaning it outperforms 77% of processors, while the Arc B580 has a percentile of 66 against all GPUs. Despite both components being above-average individually, their combination lands in a low rank because the game is exceptionally demanding and the GPU's raw performance, while respectable, is not enough to push the combo higher in the rankings.

The nearest CPU rivals for the i5-12400F — the Intel Core i7-8700K (0.1% faster), the Intel Core i5-1335U (0.3% faster), and the AMD Ryzen 5 7533HS (0.7% slower) — all have nearly identical average scores, confirming the CPU is not the weak link. Similarly, the GPU's nearest rival, the GeForce RTX 4060, is only 0.7% faster on average, which means swapping in that card would not dramatically improve the combo's rank. The low rank is more a function of the game's extreme hardware requirements than a flaw in this specific pairing.

Measured FPS Breakdown

At 1920x1080, the combo delivers its best results. Low settings produce 96.4 FPS, which is the highest recorded across all resolutions and settings. Medium settings yield 74.1 FPS, High settings drop to 57.6 FPS, and Ultra bottoms out at 52.5 FPS. The spread between Low and Ultra is 43.9 FPS, indicating that the GPU has significant headroom at 1080p but still cannot maintain 60 FPS at Ultra.

At 2560x1440, the performance tiers shift downward. Low settings average 76.9 FPS, Medium reaches 59.4 FPS, High falls to 45.2 FPS, and Ultra drops to 41.3 FPS. The gap between Low and Ultra narrows to 35.6 FPS, showing that resolution pressure is compressing the settings range.

At 3840x2160, the results are the weakest. Low settings achieve 56.4 FPS, Medium drops to 43 FPS, High falls to 31.5 FPS, and Ultra is nearly identical at 31.7 FPS. Notably, the difference between High and Ultra at 4K is just 0.2 FPS, which indicates the GPU is fully saturated and the extra visual fidelity costs almost nothing in performance because the card is already maxed out.

GPU Role

The Intel Arc B580's 12 GB of GDDR6 memory on a 192-bit bus provides 456.0 GB/s of bandwidth, which is sufficient for the large textures and terrain data in Microsoft Flight Simulator. The GPU's base and boost clocks are both 2670 MHz, and its 2560 shading units deliver 13.67 TFLOPS of FP32 compute. These specifications place the card at the 66th percentile against all GPUs, with an average benchmark score of 23021.

In this game, the GPU's role is dominant. The measured FPS data shows that the Arc B580 is the limiting component at every resolution and setting. At 1080p Low, the 96.4 FPS result suggests the card is working hard but has some headroom. By 4K Ultra, the 31.7 FPS result indicates the GPU is completely saturated, as evidenced by the negligible difference between High (31.5 FPS) and Ultra (31.7 FPS) at that resolution. The 19.6 billion transistors on a 272 mm² die running at a 190 W TDP provide enough compute for medium settings at 1440p, but the card struggles to maintain smooth frame rates at higher presets. The nearest rival, the GeForce RTX 4060, is only 0.7% faster on average, so the Arc B580 is not unusually weak for its class — it simply faces a game that demands more than mid-range GPUs can deliver.

Settings Recommendations

For this combo in Microsoft Flight Simulator, the data points to 1080p Medium as the best experience. It delivers 74.1 FPS, which is well above the 60 FPS threshold for smooth gameplay, while still offering better visual fidelity than Low (96.4 FPS). At 1080p High, the frame rate drops to 57.6 FPS, which is playable but not consistently smooth, and Ultra at 52.5 FPS is borderline for a flight simulator where precision matters.

At 1440p, the recommendation shifts to Medium settings, which produce 59.4 FPS — just under 60 FPS but still playable. High at 1440p (45.2 FPS) and Ultra (41.3 FPS) are too choppy for a smooth experience, while Low (76.9 FPS) sacrifices too much visual detail for a marginal gain. At 4K, the only viable preset is Low, which yields 56.4 FPS. Medium at 4K drops to 43 FPS, and both High and Ultra fall below 32 FPS, making them unsuitable for anything but static viewing. The data suggests that users should prioritize resolution over preset: 1440p Medium offers a better balance than 1080p Ultra, and 1080p Medium is the most consistently smooth option across all tested configurations.

CPU Role

The Intel Core i5-12400F provides 6 cores and 12 threads, with a base clock of 2.50 GHz and a boost clock of 4.40 GHz. Its 18 MB of shared L3 cache and 80 KB of L1 cache per core support the game's single-threaded flight model calculations. The CPU's benchmark scores are strong: a Cinebench R23 multi-core score of 16518 and a single-core score of 2332, plus a Geekbench single-core score of 2221 and multi-core score of 9138. These place the i5-12400F at the 77th percentile against all CPUs.

In Microsoft Flight Simulator, the CPU's role is secondary to the GPU, as the FPS scaling with resolution demonstrates. However, the CPU's single-thread performance is critical for the game's physics and AI calculations. The 3DMark single-thread score of 909 and passmark single-thread score of 3481 indicate strong per-core performance, which prevents the CPU from becoming a bottleneck even at 1080p where frame rates are highest. The nearest CPU rivals — the i7-8700K, i5-1335U, and Ryzen 5 7533HS — all perform within 0.7% of the i5-12400F, confirming that this processor is not holding back the combo. The data shows that the i5-12400F has sufficient headroom to feed the Arc B580, and any performance limitations in this game are attributable to the GPU, not the CPU. The 65 W TDP and 10 nm process node also indicate efficient operation, though the game's performance is ultimately dictated by the graphics card.
