Microsoft Flight Simulator

Microsoft Flight Simulator is one of the most demanding titles in the benchmark database, and the pairing of the Intel Core i5-12600KF with the AMD Radeon RX 7900 XT produces a dataset that clearly delineates the boundaries between CPU and GPU limitations. The measured results span three resolutions and four quality presets, offering a complete picture of how this specific hardware combination scales under load. This analysis interprets those measured frames per second (FPS) values, contextualizes them against the system's component specifications, and explains what the data indicates about the limiting factors at each configuration.

Resolution Scaling

The measured FPS data shows a pronounced and consistent drop as resolution increases from 1920x1080 to 3840x2160, which is the classic signature of a system transitioning from a CPU-bound state to a GPU-bound state. At the Low preset, the average FPS falls from 177 at 1080p to 143 at 1440p, a reduction of approximately 19%, and then again to 106 at 4K, a further 26% drop from the 1440p figure. This scaling pattern indicates that at 1080p Low, the CPU is the primary bottleneck, as the frame rate is exceptionally high and the GPU has ample headroom to render frames quickly.

Moving to the Medium preset reveals a similar trend with slightly lower absolute numbers: 138 FPS at 1080p, 111 FPS at 1440p, and 82 FPS at 4K. The percentage drop from 1080p to 1440p is about 20%, and from 1440p to 4K it is about 26%, showing that the GPU is becoming more of a limiting factor at higher resolutions, but the CPU still plays a significant role at 1080p. The High preset continues this pattern with 104 FPS at 1080p, 84 FPS at 1440p, and 62 FPS at 4K, representing drops of roughly 19% and 26% respectively.

The Ultra preset shows the most severe scaling, with average FPS at 99 for 1080p, 80 for 1440p, and 59 for 4K. The delta between 1080p and 1440p is again around 19%, and the delta between 1440p and 4K is approximately 26%. The consistency of these percentage drops across all presets is notable. It suggests that the frame rate scaling is highly systematic and tied to pixel count, which is a hallmark of a GPU-limited scenario at 4K, especially when comparing the 4K Ultra result of 59 FPS to the 1080p Ultra result of 99 FPS. The data indicates that at 4K, the RX 7900 XT is the definitive limiting component, while at 1080p, particularly on the Low preset, the i5-12600KF is what prevents the system from achieving even higher frame rates.

Settings Recommendations

The measured rows provide clear guidance on the optimal settings for this hardware combination, balancing visual fidelity with smooth gameplay. For a target of 60 FPS or higher, the Ultra preset is only viable at 1080p and 1440p, where it delivers 99 and 80 FPS respectively. At 4K, the Ultra preset drops to 59 FPS, which is just below the 60 FPS threshold, so it may not be ideal for users with a 60Hz display who want to maintain a perfect frame-pacing.

The High preset offers a more consistent experience across all resolutions. At 1080p, it achieves 104 FPS, at 1440p it reaches 84 FPS, and at 4K it holds at 62 FPS. This makes High the only preset that maintains an average FPS above 60 at 4K, making it the recommended choice for users prioritizing a smooth 4K experience. The Medium preset also performs well, with 138 FPS at 1080p, 111 FPS at 1440p, and 82 FPS at 4K, but it offers no advantage over High in terms of hitting the 60 FPS mark at 4K, making High the superior choice for visual quality without sacrificing performance.

For users with high-refresh-rate monitors at 1080p, the Low preset provides 177 FPS, which is the only configuration that approaches the 144Hz or 165Hz territory. However, the jump from Low to Medium at 1080p only costs 39 FPS (from 177 to 138), which is a moderate drop that still leaves the frame rate well above 120 FPS. The data suggests that the Medium preset is the sweet spot for 1080p high-refresh gaming, as it offers a substantial visual upgrade over Low while remaining far above the CPU-bound ceiling that limits the Low preset. The overall recommendation is to use High for 4K, High or Medium for 1440p depending on refresh rate preference, and Medium or Low for 1080p if chasing maximum frame rates.

GPU Role

The AMD Radeon RX 7900 XT is the dominant component in this pairing for most settings, and its specifications directly explain the measured performance. The GPU features 20 GB of GDDR6 memory on a 320-bit bus, providing a bandwidth of 800.0 GB/s. This large memory pool and high bandwidth are critical for Microsoft Flight Simulator, which is known for streaming vast amounts of terrain and scenery data. The 20 GB capacity ensures that even at 4K with high-resolution textures, the GPU is unlikely to be constrained by memory capacity, allowing the benchmark results to reflect pure compute performance rather than memory swapping.

The GPU's clock speeds are also relevant to the observed frame rates. The base clock is 1387 MHz, with a game clock of 2025 MHz and a boost clock of 2394 MHz. The boost clock behavior is what allows the card to reach the high frame rates seen at 1080p, where the GPU is not fully saturated and can operate at its maximum frequency. The measured FPS at 1080p Low (177 FPS) and 1080p Medium (138 FPS) show that the GPU has significant headroom, as these frame rates are likely limited by the CPU's ability to feed the renderer, not by the GPU's rasterization throughput.

The GPU's raw compute capabilities, such as 51.48 TFLOPS FP32 performance and 5376 shading units, are more than sufficient for this title. The data shows that at 4K Ultra, the GPU is the bottleneck, delivering 59 FPS. This is a very high workload, and the fact that the card can maintain nearly 60 FPS at 4K Ultra in one of the most demanding simulators on the market reflects its processing power. The 84 ray tracing cores are present, but the measured data does not specify whether ray tracing was enabled, so their impact cannot be directly assessed from these numbers. What is clear is that the GPU's combination of high bandwidth, substantial VRAM, and powerful compute units allows it to scale from a CPU-limited 1080p scenario to a GPU-limited 4K scenario without hitting a memory wall.

How This Combo Ranks

In the global database of tested combos for Microsoft Flight Simulator, this specific pairing of the Intel Core i5-12600KF and AMD Radeon RX 7900 XT ranks 664 out of 3714 tested combinations. This places it in the top 18% of all tested systems, which is a strong result considering the breadth of hardware that has been benchmarked. The rank reflects the system's ability to maintain playable frame rates across all tested configurations, with the 4K High result of 62 FPS being a particularly notable achievement that contributes to its high standing.

The rank of 664 is influenced by the CPU's mid-range positioning. The i5-12600KF has an average benchmark score of 27799, which places it at the 79th percentile among all CPUs. Its nearest rivals in the CPU benchmark database include the Intel Core i9-10900K, which is 0.3% slower, and the AMD Ryzen 7 5800X3D, which is 0.3% faster. This tight grouping indicates that the i5-12600KF is a very competitive performer, and it is unlikely to be the primary reason this combo does not rank higher. The GPU, despite its high-end specifications, has a percentile of 55 among all GPUs, which is lower than expected. Its average benchmark score of 13745 is comparable to the AMD Radeon 660M (0.5% slower) and the NVIDIA RTX A2000 Mobile (0.5% slower), which are much lower-tier products. This suggests that the RX 7900 XT's average benchmark scores may be dragged down by tests that do not favor its architecture, but in this specific game, its performance is clearly strong, as evidenced by the combo's high rank.

CPU Role

The Intel Core i5-12600KF provides the computational backbone for this system, and its specifications are directly reflected in the 1080p performance data. The CPU has 10 cores and 16 threads, with a base clock of 3.70 GHz and a boost clock of 4.90 GHz. This hybrid architecture, based on the Alder Lake design, is capable of high single-thread performance, which is essential for a flight simulator that relies heavily on a single main simulation thread. The CPU's single-thread performance is demonstrated by its 3DMark single-thread score of 1016 and its Cinebench R23 single-core score of 3302.

The data shows that at 1080p with the Low preset, the average FPS is 177. This is the highest frame rate recorded in the entire dataset, and it is likely constrained by the CPU's ability to process the game's simulation logic and issue draw calls. The fact that the frame rate drops to 143 FPS at 1440p Low and 106 FPS at 4K Low confirms that the GPU becomes the limiting factor as resolution increases. The CPU's multi-threading capabilities, as evidenced by its Cinebench R23 multi-core score of 23391 and its 3DMark max-threads score of 7952, are sufficient to avoid becoming a bottleneck at higher resolutions, but they are not enough to push the 1080p Low frame rate beyond 177 FPS.

The CPU's cache hierarchy also plays a role. It features a 20 MB shared L3 cache, which is moderate by modern standards. The data suggests that this cache size is adequate for the game's working set, as the CPU is able to maintain high frame rates without experiencing severe stuttering, which would typically manifest as low minimum FPS values. The measured minimum FPS for Medium settings at 1080p is 117 FPS, which is a healthy margin above the average, indicating that the CPU is not causing frame-time spikes. The i5-12600KF's 10 cores and 16 threads provide enough parallelism for the game's background tasks, such as AI traffic and weather simulation, while its high boost clock ensures that the primary simulation thread is processed quickly.

Measured FPS Breakdown

The complete dataset provides a detailed matrix of performance across all tested configurations. At 1920x1080, the Low preset delivers an average of 177 FPS. The Medium preset averages 138 FPS, with a minimum of 117 FPS and a maximum of 159 FPS. The High preset averages 104 FPS, and the Ultra preset averages 99 FPS. This shows a clear progression where each step up in quality costs roughly 20-40 FPS, with the largest single drop occurring from Low to Medium.

At 2560x1440, the performance scales down as expected. The Low preset averages 143 FPS, the Medium preset averages 111 FPS with a minimum of 95 FPS and a maximum of 128 FPS, the High preset averages 84 FPS, and the Ultra preset averages 80 FPS. The minimum FPS at 1440p Medium is 95 FPS, which is still very smooth, indicating that the system maintains consistent frame delivery even under load.

At 3840x2160, the frame rates become more demanding on the GPU. The Low preset averages 106 FPS, the Medium preset averages 82 FPS with a minimum of 70 FPS and a maximum of 94 FPS, the High preset averages 62 FPS, and the Ultra preset averages 59 FPS. The 4K Medium minimum of 70 FPS is notable, as it suggests that even in complex scenes, the system rarely drops below a very playable threshold. The 4K High result of 62 FPS is the highest preset that maintains an average above 60 FPS, making it the definitive recommendation for 4K owners. The 4K Ultra result of 59 FPS is borderline, and users may prefer to step down to High to ensure a stable frame rate.
