# Microsoft Flight Simulator: Intel Core i5-10400F + AMD Radeon RX 9070 XT

This combination pairs a 6-core/12-thread Intel Comet Lake processor with AMD's RDNA 4 flagship, targeting a demanding flight simulator where the CPU handles heavy simulation logic while the GPU renders dense scenery. The benchmark data shows a system that scales predictably across resolutions, with the GPU becoming the clear bottleneck at 4K Ultra while the CPU holds its own at 1080p. For a simulator known for punishing both components, this pairing delivers playable frame rates across most settings, though 4K Ultra pushes the GPU to its limits.

Resolution Scaling

The FPS drop from 1080p to 4K is substantial and reveals a GPU-bound system at higher resolutions. At High settings, the average frame rate falls from 94.1 FPS at 1920x1080 to 78.7 FPS at 2560x1440, then further to 56.4 FPS at 3840x2160. That is a 40% reduction from 1080p to 4K, indicating the RX 9070 XT is doing progressively heavier lifting as pixel count rises. The scaling is not linear — the jump from 1440p to 4K costs 22.3 FPS, while 1080p to 1440p costs only 15.4 FPS — which points to memory bandwidth and shading throughput becoming strained at 4K.

At Low settings, the pattern shifts dramatically. The RX 9070 XT delivers 131.9 FPS at 1080p, 124.7 FPS at 1440p, and 94 FPS at 4K. The smaller gap between 1080p and 1440p (7.2 FPS) suggests the CPU begins to limit performance at low graphical loads, especially at 1080p where the i5-10400F's single-thread performance matters more. The 4K Low result of 94 FPS is still higher than 4K High's 56.4 FPS, showing that reducing settings offloads work from the GPU and keeps the simulator responsive.

The scaling behavior indicates that at 1080p and 1440p, the system is reasonably balanced, but at 4K the GPU becomes the primary constraint. The i5-10400F's 6 cores and 12 threads, with a boost clock of 4.30 GHz, are sufficient to feed the GPU at lower resolutions, but the RX 9070 XT's 16 GB of GDDR6 memory and 644.6 GB/s bandwidth are the deciding factors at 4K. The data shows that users targeting 4K should expect a significant performance hit, while 1440p offers a better compromise between visual fidelity and frame rate.

FAQ

Q: Can this system run Microsoft Flight Simulator at 4K?

A: Yes, but only at reduced settings. The measured data shows 4K Low averages 94 FPS, 4K Medium averages 74 FPS, and 4K High averages 56.4 FPS. 4K Ultra drops to 50.4 FPS, which is playable but not smooth for a simulator where consistent frame pacing matters.

Q: What is the best resolution for this CPU/GPU combo?

A: 2560x1440 offers the best balance. At High settings, the system averages 78.7 FPS, which is smooth for flight simulation. 1080p High hits 94.1 FPS, but the visual fidelity gain at 1440p is more significant than the 15.4 FPS loss.

Q: How does the i5-10400F hold up in this game?

A: The CPU's 6 cores and 12 threads, with a boost clock of 4.30 GHz, are adequate. The benchmark data shows that at 1080p Low, the system reaches 131.9 FPS, suggesting the CPU is not a hard bottleneck at lower settings. However, at 4K, the GPU dominates the performance profile.

Q: Is the RX 9070 XT overkill for 1080p?

A: For this simulator, yes. At 1080p Ultra, the system averages 90.8 FPS, and at 1080p Low it hits 131.9 FPS. The GPU's 48.66 TFLOPS of FP32 performance is more than enough for 1080p, meaning the i5-10400F's single-thread score of 688 in 3dmark becomes more relevant at that resolution.

Q: How does the system perform at Ultra settings across resolutions?

A: Ultra settings produce 90.8 FPS at 1080p, 75.9 FPS at 1440p, and 50.4 FPS at 4K. The drop from 1080p to 4K is 40.4 FPS, which shows that Ultra is only viable at 1080p and 1440p for consistent smoothness.

Q: What setting changes have the biggest impact on FPS?

A: The jump from Low to Medium at 1080p costs only 5.7 FPS (131.9 to 126.2), while High to Ultra costs 3.3 FPS (94.1 to 90.8). At 4K, Low to Medium costs 20 FPS (94 to 74), and High to Ultra costs 6 FPS (56.4 to 50.4), indicating that 4K Medium is the sweet spot for quality per frame.

CPU Role

The Intel Core i5-10400F is a 6-core, 12-thread processor from the Comet Lake architecture, built on Intel's 14 nm process node. It has a base clock of 2.90 GHz and a boost clock of 4.30 GHz, with 12 MB of shared L3 cache. Its benchmark scores show a processor that is solidly mid-pack: it ranks in the 73rd percentile among all CPUs, with an average benchmark score of 14168. In multi-threaded tests, it scores 10297 in Cinebench R23 and 12115 in Passmark multithread, while single-thread performance is 1453 in Cinebench R23 and 2541 in Passmark single-thread.

In Microsoft Flight Simulator, the CPU's role is to handle simulation physics, flight model calculations, and world-building logic, which are largely single-threaded. The 3dmark single-thread score of 688 and the Cinebench R15 single-core score of 146 indicate that this CPU is not a top-tier performer for single-thread workloads. However, the measured FPS data shows that at 1080p Low, the system reaches 131.9 FPS, which suggests the CPU can keep up with the GPU at lower graphical loads.

The nearest rival comparisons show the i5-10400F sits close to the AMD EPYC 7552 (0.4% faster) and the AMD Ryzen 3 7320C (0.8% slower) in average benchmark scores. This positioning indicates that the CPU is not the limiting factor in most scenarios tested here. At 4K, the GPU's workload increases, and the FPS differences between Low (94 FPS) and Ultra (50.4 FPS) are driven by the RX 9070 XT's rendering capabilities, not the CPU's instruction throughput.

The 12 threads allow the CPU to handle background tasks and simulator threading, but the game's core logic likely relies on fewer threads. The boost clock of 4.30 GHz provides adequate headroom for the simulator's more demanding single-thread sections, but users should not expect this CPU to push frame rates significantly higher than what the data shows at 1080p.

Measured FPS Breakdown

At 1920x1080, the system delivers its highest frame rates across all settings. Low settings average 131.9 FPS, Medium 126.2 FPS, High 94.1 FPS, and Ultra 90.8 FPS. The gap between Medium and High is 32.1 FPS, which is the largest jump between adjacent settings at this resolution, indicating that High settings introduce a significant graphical load increase. The difference between High and Ultra is only 3.3 FPS, suggesting that Ultra's additional effects are not heavily taxing the RX 9070 XT at 1080p.

At 2560x1440, the frame rates scale down but remain playable. Low averages 124.7 FPS, Medium 102.2 FPS, High 78.7 FPS, and Ultra 75.9 FPS. The Medium to High drop is 23.5 FPS, similar in proportion to 1080p. The High to Ultra gap narrows to 2.8 FPS, showing that the GPU handles Ultra effects nearly as well as High at this resolution. The 1440p Low result of 124.7 FPS is close to the 1080p Low result, suggesting that the CPU is starting to become a factor at lower graphical loads.

At 3840x2160, the GPU becomes the dominant constraint. Low averages 94 FPS, Medium 74 FPS, High 56.4 FPS, and Ultra 50.4 FPS. The drop from Low to Medium is 20 FPS, and from Medium to High is 17.6 FPS, showing that each setting tier has a significant cost at 4K. The Ultra setting at 50.4 FPS is the only result below 60 FPS in the entire dataset, making it the least desirable configuration for smooth gameplay.

The data shows a consistent pattern: Medium settings offer the best frame rate per graphical quality across all resolutions. At 1080p, Medium is 34.1% faster than High; at 1440p, it is 29.9% faster; and at 4K, it is 31.2% faster. The High and Ultra settings produce similar results, with Ultra being only 3-5% slower than High in most cases, but the visual improvement from High to Ultra may not justify the frame rate cost.

How This Combo Ranks

This specific combination of the Intel Core i5-10400F and AMD Radeon RX 9070 XT ranks 537 out of 1795 tested combos in Microsoft Flight Simulator, placing it in the 70th percentile of all tested systems. This is a strong showing, given that the database includes many higher-end CPUs and GPUs. The rank reflects that the RX 9070 XT, which sits in the 82nd percentile among all GPUs with an average benchmark score of 39647, is doing most of the heavy lifting, while the i5-10400F's 73rd percentile CPU score provides adequate support.

The GPU's nearest rivals in benchmark scores include the AMD Radeon Pro 575 (0.1% slower), NVIDIA RTX A500 Mobile (0.2% faster), and AMD Radeon RX Vega 64 (0.6% slower). These comparisons show that the RX 9070 XT is a solid performer, but not an outlier in its class. The CPU's nearest rivals — the AMD EPYC 7552, AMD Ryzen 3 7320C, and Intel Core i5-8500 — are all within 1.2% of its average score, confirming that the i5-10400F is a mainstream processor.

The combo rank of 537 out of 1795 indicates that there are 1258 combinations that perform worse and 536 that perform better. This positioning suggests that the system is well-matched for the simulator, with the GPU providing most of the performance headroom. The fact that the combo ranks higher than the median (897.5) shows that this pairing is above average for Microsoft Flight Simulator, even though neither component is a top-tier performer in its respective category.

Settings Recommendations

Based on the measured FPS data, the optimal settings depend on the target resolution and desired frame rate. For 4K, Medium settings at 74 FPS provide the best balance of visual quality and smoothness, as High drops to 56.4 FPS and Ultra to 50.4 FPS. The 20 FPS penalty from Low to Medium is worth the graphical improvement, but the additional 17.6 FPS loss from Medium to High is not justified for a simulator where smooth panning is critical.

At 1440p, High settings at 78.7 FPS are the recommended choice, as they deliver a substantial visual upgrade over Medium's 102.2 FPS while maintaining a frame rate well above the 60 FPS threshold. The Ultra setting at 75.9 FPS is only 2.8 FPS slower than High, so users with high-refresh-rate monitors may prefer Ultra for the extra visual fidelity without a meaningful performance cost.

At 1080p, High settings at 94.1 FPS are ideal for most users, as they offer a significant visual improvement over Medium's 126.2 FPS while staying comfortably above 90 FPS. The Ultra setting at 90.8 FPS is also viable, with only a 3.3 FPS penalty over High. For users prioritizing maximum frame rates, Low settings at 131.9 FPS are available, but the visual compromise is steep for a game that relies heavily on scenery and weather effects.

The data consistently shows that Medium is the most efficient settings tier across all resolutions, but for the best experience, users should target High at 1080p and 1440p, and Medium at 4K. The Ultra preset is only recommended for 1080p, where the RX 9070 XT has enough headroom to absorb the extra load without dropping below 90 FPS.
