Microsoft Flight Simulator

The Intel Core i7-12700KF pairs a 12-core, 20-thread Alder Lake architecture with a 3.60 GHz base clock and a 5.00 GHz boost clock. This configuration is a strong foundation for a flight simulator, where the simulation of physics, aerodynamics, and complex avionics systems creates significant single-thread pressure. The processor’s single-thread performance, reflected in a 3DMark single-thread score of 1043 and a Cinebench R23 single-core score of 4091, is critical for maintaining a stable frame rate in this genre. The high boost clock ensures that the primary simulation thread can execute quickly, avoiding bottlenecks that would otherwise drag down the entire experience. The 20 threads provide ample headroom for background tasks, dynamic scenery generation, and the numerous auxiliary processes that a modern sim runs concurrently. The 25 MB of shared L3 cache helps keep frequently accessed data close to the cores, reducing latency. The processor’s overall position is solid, with an average benchmark score of 35355, placing it in the 89th percentile of all CPUs tested. In direct comparison, the data shows it is virtually tied with the Intel Core i5-14400, trailing by only 0.1%, and it leads the Intel Core i9-12900HX by 0.2%. This indicates that for the CPU's role in this combo, it is operating at a performance level consistent with other highly capable desktop and high-end mobile processors.

GPU Role

The NVIDIA GeForce RTX 3080 Ti is the primary engine for rendering the vast, detailed scenery of Microsoft Flight Simulator. It carries 12 GB of GDDR6X memory on a 384-bit bus, delivering 912.4 GB/s of bandwidth, which is essential for streaming high-resolution textures of terrain, aircraft, and cities. Its 80 RT cores and 320 Tensor cores are available for advanced effects, and the 10,240 shading units provide the raw computational power for pixel and vertex processing. The GPU’s boost clock of 1665 MHz allows it to sustain high throughput during demanding scenes. In the broader context of all tested GPUs, the RTX 3080 Ti sits in the 83rd percentile, with an average benchmark score of 41224. The data shows it is a close competitor to the NVIDIA GeForce RTX 3090, with a delta of -0.5%, meaning the 3080 Ti trails the 3090 by a negligible margin in synthetic tests. It is also positioned near the AMD Radeon Pro 5300, which scores 41610, a -0.9% difference. This suggests that the GPU is a high-end part that should provide a substantial level of graphical performance, but its exact impact in this game is best understood through the measured frame rates.

Resolution Scaling

The measured FPS data reveals a clear pattern of scaling across resolutions that points to a complex balance between CPU and GPU load. At 1080p with Low settings, the combo achieves 162.6 FPS, indicating that the CPU is capable of feeding the GPU at a high rate. However, at 4K with Ultra settings, the average drops to 53.5 FPS. The scaling from 1080p to 4K is not linear across settings. At High settings, the FPS drops from 93.5 at 1080p to 58.9 at 4K, a decrease of 34.9 FPS. This indicates that as resolution increases, the GPU becomes a more significant limiting factor, as the number of pixels to render quadruples. The difference between Low and Ultra settings at 4K is substantial, with a 43.7 FPS gap (97.2 vs 53.5 FPS). This suggests that while the CPU has enough headroom to handle the simulation logic, the GPU’s rendering workload is the primary constraint when pushing high resolutions and graphical fidelity. At 1440p, the scaling is more moderate, with High settings producing 78.2 FPS and Ultra producing 71.6 FPS, showing a smaller performance penalty for increasing detail compared to the jump to 4K. This indicates a balanced system at 1440p, where both components contribute to the final frame rate.

Measured FPS Breakdown

The benchmark results provide a comprehensive view of performance across four settings presets and three resolutions. At 1920x1080, the data shows a wide range of performance. With Low settings, the average FPS is 162.6, a figure that indicates a high level of headroom, likely limited by the CPU’s ability to issue draw calls. Moving to Medium settings, the average drops to 127.4 FPS, a 35.2 FPS reduction. Interestingly, High and Ultra settings at 1080p produce identical results, both averaging 93.5 FPS. This plateau suggests that at 1080p, the system becomes limited by something other than raw GPU shading power, likely the CPU’s single-thread performance in handling the simulation’s main loop, as the increase in settings does not change the output. At 2560x1440, the frame rates are lower but still robust. Low settings yield 132.3 FPS, Medium produces 99.8 FPS, and High drops to 78.2 FPS. The Ultra preset at 1440p averages 71.6 FPS, which is a solid result for a demanding flight simulator. The scaling from Medium to High at 1440p is a 21.6 FPS drop, indicating that the GPU is starting to feel the load. At 3840x2160, the GPU is clearly the bottleneck. Low settings produce 97.2 FPS, which is still very playable. Medium settings average 71.4 FPS, and High settings drop to 58.9 FPS. The Ultra preset at 4K is the most demanding scenario, with an average of 53.5 FPS. This progression shows that the combo can handle 4K at lower presets, but for the highest fidelity, users would need to accept a frame rate near 60 FPS.

How This Combo Ranks

In the specific context of Microsoft Flight Simulator, this combination of an Intel Core i7-12700KF and an NVIDIA GeForce RTX 3080 Ti is measured at a rank of 474 out of 1795 tested combos. This places it in the top quartile of all systems tested for this game. The rank indicates that while this is a high-performance pairing, there are a significant number of configurations that achieve higher average frame rates. Given the CPU's near-identical standing to rivals like the Intel Core i5-14400 and its slight lead over the Intel Core i9-12900HX, the CPU is not the primary source of limitation in this ranking. The GPU, while powerful, is also operating in a field where the RTX 3090 is slightly ahead. The measured FPS data shows that at 4K Ultra, the system delivers 53.5 FPS, which is a demanding scenario. The rank of 474 suggests that many other combinations of high-end CPUs and GPUs can produce higher frame rates, especially at lower resolutions. The fact that 1080p High and Ultra produce identical frame rates of 93.5 FPS points to a specific bottleneck in the simulation engine itself, which might be limiting the combo's ability to climb higher in the ranking. This performance plateau indicates that for this title, the combination of this specific CPU and GPU provides a balanced experience that is more constrained by the game's engine at lower resolutions than by the hardware itself.
