Microsoft Flight Simulator

Microsoft Flight Simulator is an exceptionally demanding title, and the measured data for the Intel Core i7-12700K paired with the AMD Radeon RX 570 places this combination firmly in the lower tier of tested systems. The benchmark results indicate a configuration that is heavily constrained by the graphics card at every resolution, with the CPU demonstrating sufficient headroom to handle the simulation's complex physics and scenery calculations. This analysis walks through the measured frame rates, scaling behavior, and component roles to provide a clear picture of where this combo stands.

Resolution Scaling

The FPS drop from 1080p to 4K is stark and unequivocal, revealing a system that is overwhelmingly GPU-bound. At High settings, the average frame rate falls from 28.9 FPS at 1920x1080 to 25.2 FPS at 2560x1440, and finally to 15.9 FPS at 3840x2160. This represents a 45% reduction in performance when moving from 1080p to 4K, a scaling pattern that points directly at the AMD Radeon RX 570 as the limiting component. The GPU's 4 GB GDDR5 memory and 224.0 GB/s bandwidth are simply insufficient for the texture and geometry loads at higher resolutions.

The scaling behavior is even more pronounced at Low settings, where the frame rate drops from 49.7 FPS at 1080p to 37.0 FPS at 1440p and then to 26.8 FPS at 4K. The 1080p to 4K delta of 22.9 FPS is the largest across all settings, indicating that when the CPU is less burdened by graphics work, the GPU's raw throughput limits are exposed even more clearly. Conversely, at Ultra settings, the drop from 25.7 FPS at 1080p to 15.2 FPS at 4K is a 41% loss, showing that the heaviest presets overwhelm the GPU regardless of resolution.

Notably, the 1080p to 1440p transition is relatively mild compared to the 1440p to 4K jump. At Medium settings, the former costs only 10.5 FPS (from 40.9 to 30.4), while the latter costs another 7.4 FPS (to 23.0). This suggests that the RX 570 can partially cope with the pixel count increase to 1440p, but the memory bandwidth and shading power collapse when pushed to 4K. The data shows a component that is adequate for 1080p gaming but fundamentally outclassed at higher resolutions.

How This Combo Ranks

In the comprehensive database of tested CPU-GPU combinations for Microsoft Flight Simulator, this pairing ranks 1713 out of 1795 combos. This places it in the bottom 4.6% of all tested systems, a position that reflects the GPU's age and limited capabilities rather than any deficiency in the processor. The combo rank is a holistic measure, and the data indicates that while the CPU is a strong performer, the GPU drags the overall experience down to near the bottom of the rankings.

The Intel Core i7-12700K itself holds the 89th percentile among all CPUs, with an average benchmark score of 35684. Its nearest rivals in the CPU benchmark charts are the AMD Ryzen 7 PRO 5845 (avg score 35802, a 0.3% difference) and the Intel Core i5-14500HX (avg score 35940, a 0.7% difference). These are all closely matched processors, but the GPU's average benchmark score of 30158 places it in the 74th percentile among all GPUs, with rivals like the NVIDIA GeForce RTX 5060 (avg score 30109, 0.2% delta) and AMD Radeon RX 7700 XT (avg score 30097, 0.2% delta) showing nearly identical synthetic performance.

This discrepancy is crucial: the CPU is a top-tier part, but the GPU is mid-range at best. The combination rank of 1713 reflects this imbalance, showing that in a game like Microsoft Flight Simulator, which is heavily graphics-dependent, the GPU becomes the decisive factor. The data suggests that users would see a dramatic improvement in rank by simply swapping the GPU, as the CPU's strong benchmark scores (e.g., 29241 in Cinebench R23 multi-core) indicate it is not the bottleneck.

CPU Role

The Intel Core i7-12700K is a 12-core, 20-thread processor based on the Alder Lake architecture, with a base clock of 3.60 GHz and a boost clock of 5.00 GHz. Its 25 MB of shared L3 cache and support for both DDR4 and DDR5 memory provide a robust foundation for the complex, single-threaded and multi-threaded workloads that flight simulators generate. The CPU's benchmark results are consistently strong, including a 3DMark max-threads score of 9979 and a Passmark single-thread score of 4013, indicating excellent per-core performance.

In the context of Microsoft Flight Simulator, the CPU's role is to handle the simulation's physics, weather systems, and AI traffic, while the GPU renders the world. The data shows that at 1080p Low settings, the combo achieves 49.7 FPS, which is the highest measured result across all configurations. This suggests that the CPU is capable of feeding the GPU with enough data to reach near-60 FPS territory, but the GPU's limits prevent it from going further. The 3DMark 16-thread score of 9276 and the Geekbench multi-core score of 13892 further underscore the CPU's ability to handle parallel workloads.

The CPU's 89th percentile ranking among all CPUs, with a 0.8% delta from the Intel Core i7-13800H, confirms that it is not a limiting factor in this combo. Even at 4K Ultra, where the GPU is clearly overwhelmed, the CPU's strong single-thread performance (Cinebench R23 single-core score of 4128) ensures that the simulation logic runs smoothly, but the frame rate is capped by the GPU's output. The 125W TDP and unlocked multiplier suggest headroom for overclocking, but the measured data shows that such efforts would yield no benefit in this game due to the GPU bottleneck.

Measured FPS Breakdown

The measured FPS data provides a comprehensive view of the combo's performance across three resolutions and four settings presets. At 1920x1080, the frame rates range from 49.7 FPS at Low settings to 25.7 FPS at Ultra, with Medium achieving 40.9 FPS and High at 28.9 FPS. This demonstrates that at 1080p, the combo is playable at Low and Medium settings, but High and Ultra push the GPU beyond its comfort zone, resulting in sub-30 FPS averages.

Moving to 2560x1440, the frame rates drop noticeably: Low delivers 37.0 FPS, Medium 30.4 FPS, High 25.2 FPS, and Ultra 22.1 FPS. The 1440p results show that only Low settings remain comfortably above 30 FPS, with Medium barely hitting that threshold. The gap between Low and Ultra at 1440p is 14.9 FPS, indicating that the GPU's shading units and memory bandwidth are stretched thin at this resolution.

At 3840x2160, the results are uniformly poor: Low achieves 26.8 FPS, Medium 23.0 FPS, High 15.9 FPS, and Ultra 15.2 FPS. The 4K data shows a system that is entirely GPU-limited, with even the lowest settings failing to reach 30 FPS. The delta between Low and High at 4K is 10.9 FPS, which is smaller than the corresponding 21.2 FPS delta at 1080p, further confirming that the GPU is saturated at 4K regardless of settings. The most impactful settings change is from Low to Medium at 1080p, which costs 8.8 FPS, while the jump from Medium to High costs 12.0 FPS, showing that the GPU's fill rate is the primary constraint.

Settings Recommendations

Based on the measured FPS data, the optimal experience for this combo is at 1920x1080 with Low settings, which achieves 49.7 FPS — the highest frame rate in the entire dataset. This preset provides the smoothest gameplay, which is critical for a flight simulator where precise control inputs matter. The Low settings also reduce the GPU's memory pressure, mitigating the 4 GB VRAM limitation.

For users who prioritize visual fidelity over smoothness, 1080p Medium at 40.9 FPS is a viable alternative, offering a significant visual improvement over Low while still maintaining a playable frame rate. The 8.8 FPS cost of moving from Low to Medium is a worthwhile trade-off for the enhanced scenery detail. However, the jump to High at 1080p (28.9 FPS) and Ultra (25.7 FPS) is not recommended, as the frame rate drops below 30 FPS, which can lead to a noticeable stutter in a simulation that requires smooth panning and camera movement.

At 1440p, only Low settings (37.0 FPS) are acceptable, with Medium (30.4 FPS) being borderline and High/Ultra falling below 26 FPS. The 4K resolution is not viable for this combo, as even Low settings (26.8 FPS) fail to reach 30 FPS, and Ultra (15.2 FPS) is effectively unplayable. Therefore, the best experience is firmly at 1080p with Low or Medium settings, prioritizing frame rate over graphical detail to compensate for the GPU's limitations.
