# Microsoft Flight Simulator — Intel Core i5-14400F + AMD Radeon RX 6600 XT

This combination ranks 1270th out of 1795 tested combos in Microsoft Flight Simulator, placing it in the lower-middle tier of the database. The pairing of Intel's 10-core Raptor Lake refresh CPU with AMD's RDNA 2 mid-range GPU produces playable but not exceptional results, with the data indicating that the graphics card is the primary constraint at higher resolutions while the processor holds up well at 1080p. The measured frame rates show a clear pattern: this system is best suited for 1080p gaming, acceptable at 1440p with moderate settings, and only marginally playable at 4K on lower presets.

Resolution Scaling

The frame rate drop from 1080p to 4K reveals a GPU-bound configuration. At Low settings, the average FPS falls from 98.8 at 1920x1080 to 81.2 at 2560x1440 (a 17.8% reduction), then to 56.5 at 3840x2160 (a 30.4% further drop). This steep decline as pixel count increases strongly indicates that the AMD Radeon RX 6600 XT, with its 8 GB of GDDR6 memory on a 128-bit bus, is the limiting factor at higher resolutions. The 256.0 GB/s memory bandwidth becomes increasingly strained as resolution scales.

The pattern holds across all settings presets. At Ultra, the drop from 1080p to 4K is from 57.9 FPS down to 33.5 FPS — a 42.1% reduction. At Medium, the drop is from 78.5 to 46.8 FPS (40.4% lower). The consistency of these reductions across presets confirms that resolution scaling, not CPU throughput, governs performance here. The Intel Core i5-14400F, with its boost clock of 4.70 GHz and 20 MB of shared L3 cache, has ample headroom; the data shows the GPU saturating well before the CPU becomes a bottleneck.

Interestingly, the gap between Low and Ultra settings narrows as resolution increases. At 1080p, Low delivers 98.8 FPS versus 57.9 FPS at Ultra — a 70.6% difference. At 4K, Low yields 56.5 FPS versus 33.5 FPS at Ultra — a 68.7% difference. This suggests that even at lower settings, the GPU's compute resources (10.60 TFLOPS FP32) are fully engaged at 4K, leaving little room for quality improvements without significant frame rate penalties.

FAQ

Q: Is this combo capable of 60+ FPS at 1080p?

A: Yes, at Low and Medium settings. The measured data shows 98.8 FPS at Low and 78.5 FPS at Medium for 1920x1080. High settings produce 58.7 FPS, which is just under 60, while Ultra drops to 57.9 FPS.

Q: What frame rate can I expect at 1440p with High settings?

A: The measured average is 47.7 FPS at 2560x1440 with High settings. This is below the 60 FPS threshold but remains playable for a flight simulator, which is less sensitive to frame rate fluctuations than fast-paced action games.

Q: Can this system handle 4K resolution?

A: Only with compromises. At 3840x2160, Low settings produce 56.5 FPS, Medium drops to 46.8 FPS, High yields 35.7 FPS, and Ultra falls to 33.5 FPS. Users targeting 4K will need to accept Low or Medium presets for smooth gameplay.

A: Based on the measured data, 8 GB of GDDR6 memory appears adequate for Microsoft Flight Simulator at the tested settings. The frame rates decline smoothly with resolution, suggesting no catastrophic VRAM overflow even at 4K Ultra, though the 33.5 FPS result indicates the GPU is heavily strained.

How This Combo Ranks

The combination of the Intel Core i5-14400F and AMD Radeon RX 6600 XT ranks 1270th out of 1795 tested combos in Microsoft Flight Simulator. This places the system in the 29th percentile of all tested configurations — meaning roughly 71% of tested combos outperform it in this specific title. The rank reflects the mid-range positioning of both components: the CPU sits at the 88th percentile among all CPUs in the database, while the GPU is at the 71st percentile among all GPUs. The lower combo rank relative to the individual component percentiles suggests that Microsoft Flight Simulator's demanding rendering workload punishes the GPU more heavily than typical benchmarks would indicate.

The delta between the CPU's strong standing (88th percentile) and the overall combo rank (29th percentile among combos) is telling. It implies that in this game, the RX 6600 XT holds the system back relative to what the processor could otherwise support. For context, the CPU's nearest rivals — the Intel Core i7-12800H, AMD Ryzen 5 PRO 7645, and AMD Ryzen 7 250 — all have average benchmark scores within 0.2% of the i5-14400F, so the processor itself is not the differentiating factor in this ranking.

Measured FPS Breakdown

At 1920x1080, the system delivers its best results. Low settings produce 98.8 FPS, Medium reduces this to 78.5 FPS, High drops further to 58.7 FPS, and Ultra yields 57.9 FPS. The small gap between High and Ultra (0.8 FPS) suggests that the Ultra preset adds visual fidelity without a proportional performance cost at this resolution.

Moving to 2560x1440, the frame rates decline noticeably. Low settings give 81.2 FPS, Medium produces 64.5 FPS, High falls to 47.7 FPS, and Ultra reaches 43.6 FPS. The delta between Low and Ultra widens to 37.6 FPS at this resolution, indicating that GPU load scales significantly with quality settings when pixel count rises.

At 3840x2160, performance becomes marginal. Low settings yield 56.5 FPS, Medium drops to 46.8 FPS, High produces 35.7 FPS, and Ultra bottoms out at 33.5 FPS. The progression from Low to Ultra at 4K shows a 23.0 FPS spread, with each preset step costing roughly 7-11 FPS. The data indicates that only Low settings can sustain near-60 FPS at 4K, while Medium remains playable but not smooth by conventional standards.

CPU Role

The Intel Core i5-14400F features 10 cores and 16 threads, with a base clock of 2.50 GHz and a boost clock of 4.70 GHz. Its Raptor Lake architecture, built on Intel's 10 nm process, includes 20 MB of shared L3 cache and 1.25 MB of L2 cache per core. Benchmark results show strong single-thread performance (3093 in Cinebench R23 single-core) and robust multi-core capabilities (21914 in Cinebench R23 multi-core), placing it at the 88th percentile among all CPUs.

In Microsoft Flight Simulator, the CPU's role is primarily handling simulation logic, physics, and draw-call preparation. The data shows that at 1080p Low, the system achieves 98.8 FPS, which indicates the CPU can feed the GPU at a high rate. The fact that frame rates at 4K drop to 56.5 FPS even at Low settings — while the CPU's workload remains largely resolution-independent — confirms that the processor is not the limiting factor in this pairing. The i5-14400F's Passmark single-thread score of 3723 and Geekbench single-core score of 2333 support its capability in single-threaded game workloads.

The CPU's 65 W TDP and dual-channel DDR4/DDR5 memory support make it a mainstream part, but its 10-core configuration provides ample headroom for the flight simulator's multithreaded systems. The Passmark physics score of 1594 and integer math score of 81964 indicate solid computational throughput that would not bottleneck the RX 6600 XT in this title.

Settings Recommendations

For users prioritizing smooth frame rates, the Low preset at 1920x1080 delivers the best experience with 98.8 FPS — a clear margin above the 60 FPS threshold. However, the Medium preset at 78.5 FPS offers a substantial visual upgrade for only a 20.3 FPS penalty, making it the recommended compromise for most players at 1080p. High settings at 58.7 FPS and Ultra at 57.9 FPS are functionally equivalent in performance, so choosing Ultra provides better visuals at virtually no cost.

At 2560x1440, the Medium preset at 64.5 FPS is the only setting above 60 FPS for this resolution. Low at 81.2 FPS is the smoothest option but sacrifices significant visual quality. High at 47.7 FPS and Ultra at 43.6 FPS are playable for a flight simulator but will feel less fluid. The 1440p Ultra result of 43.6 FPS is only 10.1 FPS higher than the 4K Low result of 56.5 FPS is not the right comparison — rather, 1440p Ultra delivers 43.6 FPS, which is 12.9 FPS lower than 4K Low.

For 4K, only the Low preset (56.5 FPS) approaches playable smoothness. Medium at 46.8 FPS is acceptable for casual flight, while High (35.7 FPS) and Ultra (33.5 FPS) are best reserved for screenshots or stationary viewing. Given the genre's tolerance for lower frame rates, 4K Medium at 46.8 FPS may be the most balanced choice for visual fidelity, but users seeking consistent performance should target 1080p Medium or 1440p Low.

GPU Role

The AMD Radeon RX 6600 XT, built on the RDNA 2.0 architecture with the Navi 23 chip, features 2048 shading units, 128 texture mapping units, and 64 raster operation pipelines. Its boost clock of 2589 MHz and game clock of 2359 MHz drive 10.60 TFLOPS of FP32 compute. The 8 GB of GDDR6 memory on a 128-bit bus delivers 256.0 GB/s of bandwidth, which proves adequate for 1080p but strained at higher resolutions.

The GPU's benchmark profile shows a Passmark G3D score of 16461 and a 3DMark Steel Nomad DX12 score of 1804, placing it at the 71st percentile among all GPUs. Its nearest rivals in raw score include the NVIDIA GeForce GTX 980 Ti (27956, 0.1% behind), AMD Radeon R9 M395X (27883, 0.4% behind), and NVIDIA GeForce RTX 3070 (28238, 0.9% ahead). This positions the RX 6600 XT as a solid mid-range part that competes with older high-end cards.

In Microsoft Flight Simulator, the GPU's rendering workload dominates performance. The measured frame rates show that the card loses 42.1% of its 1080p Ultra performance when moving to 4K Ultra (57.9 to 33.5 FPS), and 42.7% of its 1080p Low performance at 4K Low (98.8 to 56.5 FPS). The 8 GB VRAM capacity does not appear to cause a hard failure at 4K — the frame rate declines smoothly rather than collapsing — but the 128-bit memory interface limits throughput. The card's 165.7 GPixel/s pixel rate and 331.4 GTexel/s texture rate are sufficient for 1080p and 1440p but struggle to maintain high fill rates at 4K, especially with the Ultra preset's increased geometric and texture detail.
