Microsoft Flight Simulator

Microsoft Flight Simulator presents one of the most demanding rendering workloads in the benchmark database, and the measured results for the Intel Core i7-12700KF paired with the AMD Radeon RX 6800 XT reveal a configuration that scales predictably with resolution and settings. The data, drawn from actual measurement rather than estimation, shows a system that is capable of smooth flight at 1080p and 1440p, but which begins to strain at 4K with higher quality presets. The relationship between the CPU's computational headroom and the GPU's raw throughput is the defining characteristic of these results, with the balance shifting as the pixel count increases.

Resolution Scaling

The measured frame rates show a clear and consistent decline as resolution increases from 1920x1080 to 3840x2160, which is typical for a title where pixel fill rate becomes the dominant factor at higher resolutions. At Low settings, the average frame rate drops from 151.7 FPS at 1080p to 122.5 FPS at 1440p and then to 90.9 FPS at 4K. This represents a 19.3% reduction from 1080p to 1440p and a further 25.8% reduction from 1440p to 4K. The scaling pattern indicates that even at Low settings, the GPU is becoming the limiting factor at 4K, as the CPU is likely still able to feed frames quickly at the lower resolution.

The Medium preset tells a similar story, with average FPS falling from 116.4 at 1080p to 94.2 at 1440p and 66.9 at 4K. The absolute drop from 1080p to 4K is 49.5 FPS, which is a 42.5% reduction in performance. At High settings, the figures are 88.0 FPS at 1080p, 73.3 FPS at 1440p, and 51.8 FPS at 4K. The Ultra preset, which is the most demanding, yields 82.3 FPS at 1080p, 69.9 FPS at 1440p, and 47.7 FPS at 4K. The difference between the 1080p and 4K results at Ultra is 34.6 FPS, a 42.0% reduction.

What the data reveals is a system where the CPU is not the bottleneck at any resolution, even at 1080p with Low settings. The 151.7 FPS figure at 1080p Low is likely near the ceiling of what the game engine can deliver with this CPU, but the GPU is clearly being pushed harder as resolution climbs. The fact that the gap between Low and Ultra at 1080p is only 69.4 FPS, while at 4K it is 43.2 FPS, suggests that the GPU's shading and memory bandwidth are being taxed more heavily at higher resolutions. The RX 6800 XT, with its 16 GB of GDDR6 memory and 512.0 GB/s bandwidth, is sufficient for 4K, but the frame rates at Ultra remain below the 60 FPS threshold.

CPU Role

The Intel Core i7-12700KF 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 benchmark scores are strong, with a Cinebench R23 multicore score of 28979 and a single-core score of 4091. The processor sits in the 89th percentile of all CPUs, and its nearest rivals in the database include the Intel Core i5-14400, which scores 35336 (a 0.1% delta), and the Intel Core i9-12900HX, which scores 35289 (a 0.2% delta). These figures indicate that the 12700KF is performing at a level consistent with its position in the market.

In Microsoft Flight Simulator, the CPU's role is primarily to handle the simulation logic, physics, and draw call preparation. The game is known to be sensitive to single-threaded performance, and the 12700KF's single-core score of 4091 in Cinebench R23 is robust. The measured frame rates suggest that the CPU is not holding back the GPU, as the scaling from 1080p to 4K is consistent with GPU-bound behavior. At 1080p Low, the 151.7 FPS result is likely close to the engine's physics or draw call limit, but the CPU's 20 threads provide ample headroom for background tasks and complex scenes. The L3 cache of 25 MB (shared) helps with the large data sets used in flight simulation, and the 20 threads ensure that the simulation can run alongside the rendering pipeline without stuttering.

The data shows that the 12700KF is a capable partner for the RX 6800 XT in this title. The CPU's performance percentile of 89 relative to all CPUs indicates that it is well above average, and its benchmark scores in 3DMark (max_threads score of 9983) and Geekbench (multicore score of 13596) align with its role as a high-end desktop processor. For a flight simulator, where frame pacing is critical for smooth visuals, the CPU's consistent performance is a positive factor.

Settings Recommendations

The measured FPS data provides clear guidance on which settings preset offers the best experience for this combination. At 1920x1080, the High preset delivers 88.0 FPS, which is well above the 60 FPS target for smooth gameplay. The Medium preset at 116.4 FPS is even smoother, but the visual fidelity gains from High are likely worth the 28.4 FPS reduction. The Ultra preset at 82.3 FPS is also playable, but the marginal visual improvement over High may not justify the 5.7 FPS drop. For 1080p, High is the recommended preset, as it balances image quality with a frame rate that leaves headroom for complex scenes.

At 2560x1440, the High preset yields 73.3 FPS, which is still above 60 FPS and provides a smooth experience. The Medium preset at 94.2 FPS is excellent for competitive play or fast-moving scenarios, but for a flight simulator, the higher fidelity of High is preferable. The Ultra preset at 69.9 FPS is also viable, but it is closer to the 60 FPS threshold, and any demanding scenery could cause dips. The recommended preset for 1440p is High, as it offers a 4.9% improvement over Ultra in frame rate while likely providing a similar visual experience in most scenarios.

At 3840x2160, the situation changes. The High preset delivers 51.8 FPS, which is below the 60 FPS target, while the Medium preset at 66.9 FPS is the only option that exceeds 60 FPS. The Low preset at 90.9 FPS is very smooth, but the visual compromise is significant. For 4K, the Medium preset is the recommended choice, as it provides a playable frame rate without the severe visual degradation of Low. The Ultra preset at 47.7 FPS is the most demanding, but the 4.1 FPS difference between High and Ultra is minimal, suggesting that the GPU is hitting a ceiling. The data indicates that this combination is best suited for 1080p and 1440p gaming, with 4K requiring a reduction in settings to maintain smooth performance.

How This Combo Ranks

In the benchmark database, this specific combination of the Intel Core i7-12700KF and the AMD Radeon RX 6800 XT ranks 629th out of 1795 tested combos in Microsoft Flight Simulator. This places it in the top 35% of all systems, which is a strong showing given the game's demanding nature. The rank reflects the balanced performance of the CPU and GPU, with neither component being a clear weak point. The combo's position is likely influenced by the CPU's high single-threaded performance and the GPU's substantial memory bandwidth, both of which are critical for flight simulation.

The rank of 629 out of 1795 means that this system outperforms the majority of tested configurations, but it is not at the very top tier. Systems with higher-end GPUs, such as those with more shading units or faster memory, would likely rank higher, as would CPUs with even stronger single-core performance. However, for a mid-to-high-end desktop configuration, this combo is well above average. The data shows that the RX 6800 XT's 4608 shading units and 128 ROPs are sufficient for this game at 1080p and 1440p, but the 4K results suggest that a more powerful GPU would be needed to maintain high frame rates at Ultra settings. The combo's rank reflects the synergy between the 12700KF's 20 threads and the RX 6800 XT's 16 GB of VRAM, which allows for large textures and complex scenes without memory-related stuttering.

GPU Role

The AMD Radeon RX 6800 XT is a high-end graphics card based on the RDNA 2.0 architecture, with a chip size of 520 mm² and 26,800 million transistors. It operates at a base clock of 1825 MHz and a boost clock of 2250 MHz, with a game clock of 2015 MHz. The GPU features 4608 shading units, 288 TMUs, and 128 ROPs, along with 72 ray tracing cores. Its memory subsystem consists of 16 GB of GDDR6 memory on a 256-bit bus, delivering a bandwidth of 512.0 GB/s. The GPU's FP32 performance is rated at 20.74 TFLOPS, and its texture rate is 648.0 GTexel/s.

In Microsoft Flight Simulator, the GPU's role is to render the vast landscapes, detailed aircraft models, and dynamic weather effects. The measured frame rates show that the RX 6800 XT is capable of handling this workload, but the 4K results are limited by its raw compute power. At 4K Ultra, the 47.7 FPS average is below the 60 FPS target, indicating that the GPU is the bottleneck. The GPU's 16 GB of VRAM is sufficient for the game's high-resolution textures, but the shading units are not enough to maintain high frame rates at 4K with the most demanding presets.

The GPU's benchmark scores support its performance in this title. Its Passmark G3D score of 24980 places it in the 87th percentile of all GPUs, and its nearest rivals include the NVIDIA GeForce RTX 4070 Ti SUPER, which scores 48704 (a 2.6% delta), and the NVIDIA RTX A1000, which scores 50826 (a -1.7% delta). The RX 6800 XT's performance in 3DMark Steel Nomad (3689) and Geekbench Vulkan (152200) indicates that it is a strong DirectX 12 performer, which is relevant for a game like Microsoft Flight Simulator. The data shows that the GPU is the primary factor in the 4K performance drop, as the CPU is likely still able to provide enough data for the rendering pipeline. For users who want to play at 4K with this combo, the Medium preset is the best choice, as it balances visual quality with a playable frame rate.
