Microsoft Flight Simulator

Microsoft Flight Simulator presents one of the most demanding rendering workloads in PC gaming, and the pairing of the Intel Core i7-14700K with the AMD Radeon RX 9070 produces a revealing dataset. The measured frames per second across resolutions and presets show a system that is consistently capable but whose bottlenecks shift dramatically depending on the settings applied. This analysis examines the raw numbers to understand where the limiting factor lies and what the data implies for pilots seeking smooth skies.

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

The FPS drop from 1080p to 4K is steep, but the pattern is not uniform across all settings. At Low settings, the average frame rate falls from 154.8 FPS at 1920x1080 to 90.4 FPS at 3840x2160, a reduction of 64.4 FPS or roughly 42%. At Medium settings, the drop is from 123 FPS to 71.9 FPS, a 51.1 FPS decline. The High preset sees a fall from 88.9 FPS to 50.3 FPS, a 38.6 FPS reduction. Ultra settings show a similar absolute drop, going from 87.2 FPS at 1080p to 50.5 FPS at 4K, a difference of 36.7 FPS.

The relative scaling tells a more nuanced story. At Low settings, the 1080p result of 154.8 FPS is extremely high, suggesting the CPU has significant headroom to feed the GPU. As resolution increases, the GPU becomes more saturated, but even at 4K Low, the system maintains 90.4 FPS, which indicates the RX 9070 is not the limiting factor at this preset. The gap between 1440p and 4K at Low is 34.8 FPS (from 125.2 to 90.4), which is a substantial 28% drop. This contrasts with the High preset, where the drop from 1440p (70.5 FPS) to 4K (50.3 FPS) is 20.2 FPS, a 29% decline.

The data implies that at higher presets, the scaling behavior changes character. The difference between 1080p High (88.9 FPS) and 1440p High (70.5 FPS) is 18.4 FPS, while the difference between 1440p High and 4K High is 20.2 FPS. These are relatively consistent absolute drops, which suggests that at High settings, the workload is becoming more evenly balanced between CPU and GPU. The Ultra preset shows a nearly identical pattern, with a 18.3 FPS drop from 1080p to 1440p and a 18.4 FPS drop from 1440p to 4K. This consistent scaling indicates that the game's engine is effectively utilizing the available hardware at these higher settings, though the absolute numbers are lower than the Low preset's results.

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

The AMD Radeon RX 9070 brings 16 GB of GDDR6 memory on a 256-bit bus, with a memory bandwidth of 644.6 GB/s. The 16 GB frame buffer is a critical asset for Microsoft Flight Simulator, which is known for loading vast textures for terrain and aircraft. The data shows that the GPU is not running out of memory at any tested resolution, as the frame rates do not collapse at 4K, which would be a symptom of VRAM spilling to system memory. The boost clock of 2520 MHz and game clock of 2070 MHz provide the raw compute throughput, with the card rated at 36.13 TFLOPS FP32 performance.

The GPU's role becomes more pronounced as resolution rises. At 1080p Low, the 154.8 FPS result far exceeds what the GPU's 3DMark Steel Nomad score of 6290 might suggest for a typical title, but Flight Simulator's CPU-heavy rendering pipeline at lower resolutions means the RX 9070 is not fully taxed. The passmark G3D score of 25381 places this GPU in the 79th percentile of all GPUs, and the data shows it handles the 4K Ultra preset at 50.5 FPS, which is playable but not ideal for a flight sim where smooth panning is essential. The transition from Low to Ultra at 4K costs 39.9 FPS (from 90.4 to 50.5), which demonstrates the GPU is the dominant factor at this resolution.

The 16 GB VRAM capacity appears to be sufficient for the Ultra preset at 4K, as the frame rate does not exhibit the erratic drops that would indicate memory pressure. The memory clock of 2518 MHz (20.1 Gbps effective) combined with the 644.6 GB/s bandwidth ensures that texture streaming does not become a bottleneck, even with the dense scenery that Flight Simulator renders. The data suggests that the GPU's compute capabilities, not its memory subsystem, are the primary constraint at 4K Ultra.

How This Combo Ranks — use comboRankInGame vs other tested combos

This specific combination of the Intel Core i7-14700K and AMD Radeon RX 9070 achieves a rank of 589 out of 1795 tested combos in Microsoft Flight Simulator. This places the pairing in the top third of all tested systems, which is a strong showing given the game's notorious demands. The rank of 589 means that 1206 other CPU-GPU combinations performed better in this title, while 588 performed worse. This is a mid-to-high tier result, suggesting that while the system is capable, there are more powerful configurations available.

The CPU itself sits in the 96th percentile of all CPUs based on its average benchmark score of 70074. Its nearest rivals include the Intel Core i7-14700KF, which has a deltaPct of 0, indicating identical performance, and the AMD Ryzen 9 9950X, which is 0.5% faster. The GPU, however, is only in the 79th percentile of all GPUs, with an average score of 34780. Its nearest rivals are the NVIDIA A2 (0.2% slower) and the Quadro GV100 (0.3% faster). This disparity between the CPU's high percentile and the GPU's lower percentile suggests that the combo rank is limited more by the graphics card than the processor.

The rank of 589 out of 1795 implies that many other combos with similar CPUs but faster GPUs outperform this configuration. Conversely, combos with slower CPUs but equivalent GPUs would likely rank lower. The data indicates that the i7-14700K has the headroom to drive a more powerful GPU, as evidenced by its 28 threads and 20 cores, but the RX 9070's 79th percentile standing caps the overall performance. This is a balanced pairing, but not one that maximizes the CPU's potential in this specific title.

Measured FPS Breakdown — resolution by resolution, settings by settings, exact numbers

At 1920x1080, the system delivers its highest frame rates. The Low preset achieves 154.8 FPS, which is exceptionally smooth for a flight simulator. Medium settings drop to 123 FPS, still well above the threshold for a fluid experience. High settings yield 88.9 FPS, and Ultra produces 87.2 FPS. The difference between High and Ultra at 1080p is only 1.7 FPS, which is negligible and suggests that Ultra is not significantly more demanding at this resolution.

Moving to 2560x1440, the frame rates decrease but remain respectable. Low settings produce 125.2 FPS, a 29.6 FPS drop from 1080p. Medium settings hit 94.6 FPS, while High settings average 70.5 FPS. Ultra at 1440p gives 68.9 FPS, which is only 1.6 FPS less than High. The gap between Low and Ultra at 1440p is 56.3 FPS, showing the significant impact of preset selection.

At 3840x2160, the system starts to show its limits. Low settings average 90.4 FPS, which is still smooth. Medium settings drop to 71.9 FPS. High settings produce 50.3 FPS, and Ultra yields 50.5 FPS. Interestingly, the Ultra preset at 4K (50.5 FPS) is marginally faster than High (50.3 FPS), which is likely due to measurement variance but suggests that the game's Ultra preset is not always more demanding than High in every scene. The 4K results show that the system can handle 4K, but only at Low or Medium settings for a consistently smooth experience above 60 FPS.

Settings Recommendations

For a smooth experience at 4K, the Medium preset is the best option, yielding 71.9 FPS, which is comfortably above the 60 FPS threshold. The Low preset at 4K offers even higher performance at 90.4 FPS, but the visual compromise may be significant. At 1440p, the High preset provides 70.5 FPS, which is a good balance of visual quality and performance, while Ultra at 68.9 FPS is also viable. The data shows that the jump from Medium to High at 1440p costs 24.1 FPS (from 94.6 to 70.5), so users who prioritize frame rate should stick with Medium.

At 1080p, the system has ample performance for any preset. Ultra at 87.2 FPS is perfectly playable, and the 1.7 FPS difference between High and Ultra makes Ultra the obvious choice for the highest visual fidelity. The Low preset at 1080p (154.8 FPS) is only useful for competitive scenarios or if the user has a very high refresh rate monitor. The data suggests that for most users, the Medium preset at 4K or the High preset at 1440p offers the best experience, as these settings maintain frame rates above 70 FPS while providing enhanced visuals over the Low preset.

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

The Intel Core i7-14700K is a 20-core, 28-thread processor based on the Raptor Lake architecture, with a base clock of 3.40 GHz and a boost clock of 5.60 GHz. The 33 MB of shared L3 cache and 2 MB per-core L2 cache provide substantial on-die storage for game data. In Microsoft Flight Simulator, which is known for its complex physics and AI calculations, the CPU's multi-threading capabilities are heavily utilized. The Cinebench R23 multi-core score of 44534 and single-core score of 6287 demonstrate strong performance in both heavily threaded and lightly threaded workloads.

The data shows that at 1080p Low, the system achieves 154.8 FPS, which is likely near the CPU's limit for this game's engine. The fact that the frame rate drops to 125.2 FPS at 1440p Low and 90.4 FPS at 4K Low indicates that the GPU is taking over as the bottleneck at higher resolutions. This is a classic sign of a well-balanced system where the CPU can feed the GPU at lower resolutions, but the GPU's pixel throughput becomes the limiting factor at 4K.

The CPU's 96th percentile ranking among all CPUs suggests that it is not the weak link in this pairing. The boost clock of 5.60 GHz is particularly valuable for Flight Simulator's single-threaded rendering tasks, and the 28 threads handle the background simulation work. The data implies that if a user were to upgrade the GPU to a faster model, the i7-14700K would likely still be able to keep up, as the 1080p Low result of 154.8 FPS indicates the CPU has headroom beyond what the RX 9070 can deliver at that resolution.
