Microsoft Flight Simulator

Microsoft Flight Simulator is notoriously demanding, and this pairing of the Intel Core i7-14700KF with the AMD Radeon RX 6750 XT shows a clear narrative about where bottlenecks lie. The data indicates a system that is heavily reliant on the GPU at higher resolutions, while the substantial CPU resources provide a strong foundation for the lower-resolution, higher-refresh-rate end of the spectrum. This is a classic example of a balanced 1440p setup that can stretch into 4K territory with some graphical compromises.

Resolution Scaling

The measured FPS data reveals a predictable but steep decline as resolution increases, confirming that the AMD Radeon RX 6750 XT is the primary limiting factor in this pairing. At 1080p with High settings, the system achieves an average of 74 FPS. Moving to 1440p drops that average to 60 FPS, a 19% reduction. The jump to 4K is more punishing, with the average falling to 44 FPS, which is a further 27% drop from the 1440p figure and a 41% decline from the 1080p baseline.

This scaling pattern is crucial for understanding the system's behavior. The fact that the 4K High average is 44 FPS, while the 1080p Ultra average is 71 FPS, suggests that the GPU is being saturated by the pixel count at 4K, leaving little headroom for visual fidelity. The performance gap between 1080p and 1440p is moderate, but the gap between 1440p and 4K is significantly larger, indicating that the GPU's memory bandwidth and compute resources are stretched thin at the highest resolution.

The data also shows how settings impact performance at the same resolution. At 4K, dropping from High to Medium yields a significant 15 FPS average increase (from 44 to 59 FPS), and dropping to Low yields a 31 FPS increase (from 44 to 75 FPS). This wide variance suggests that the GPU is the bottleneck; if the CPU were the limiting factor, the FPS would remain relatively flat regardless of the graphics settings. The scaling from Low to Ultra at 1080p (from 127 FPS to 71 FPS) further confirms this, as the CPU can clearly push well beyond 100 FPS, but the GPU's rendering workload at Ultra settings brings it down.

CPU Role

The Intel Core i7-14700KF is a powerhouse with 20 cores and 28 threads, built on the Raptor Lake architecture. Its benchmark scores are impressive, including a Cinebench R23 multi-core score of 44167 and a single-core score of 6235. This raw computational strength is what allows the system to achieve high frame rates at lower resolutions where the GPU is not the primary bottleneck.

In this game, the CPU's role is to handle the complex simulation logic, physics, and AI that Microsoft Flight Simulator is known for. The high single-core performance ensures that the main game thread runs efficiently, while the multi-core capabilities can assist with background tasks and asset streaming. The data suggests the CPU is more than capable for this task. At 1080p Low, the system averages 127 FPS, which is likely near the upper limit of what the game engine can process, indicating the CPU is not holding the system back.

The CPU's percentileVsAllCpus of 94 places it in the top tier of processors, and its average benchmark score of 70163 is nearly identical to its nearest rival, the AMD Ryzen 7 9700F, which scores 69996 with a 0.2% delta. This means that in synthetic benchmarks, these two CPUs are effectively interchangeable. However, the 14700KF's high core count and 33 MB of shared L3 cache likely provide a solid foundation for maintaining stable frame times in a simulation-heavy game like this.

How This Combo Ranks

The combined Intel Core i7-14700KF and AMD Radeon RX 6750 XT configuration ranks at 1674 out of 3714 tested combos in this game's database. This places it in the 45th percentile of all possible pairings, which is a solid but not exceptional position. This rank is primarily dragged down by the GPU, as the CPU is a top-6% performer, while the GPU's percentileVsAllGpus is 71, making it a mid-range to upper-mid-range component.

The ranking indicates that this is a sensible pairing for a 1440p gaming setup. It is not a top-tier combination for 4K or maximum settings, but it is far from a weak one. The data shows that this combo is well-optimized for the middle ground of gaming, where the CPU's strength can be leveraged to maintain high frame rates without the GPU being completely overwhelmed. The rank suggests that while many other combinations are faster, this one offers a balanced experience that will satisfy most users targeting high refresh rates at 1440p.

Measured FPS Breakdown

The measured FPS data provides a complete picture of the system's capabilities. At 1080p, the system performs admirably. With Low settings, it averages 127 FPS, which is excellent for fast-paced action. Medium settings drop the average to 99 FPS, with a minimum of 84 FPS and a maximum of 113 FPS, indicating smooth gameplay. High settings yield an average of 74 FPS, and Ultra settings produce an average of 71 FPS. The relatively small difference between High and Ultra at this resolution suggests that the CPU is starting to become a secondary factor, but the GPU is still handling the workload adequately.

At 1440p, the numbers are still very playable. Low settings average 102 FPS, making the game feel very fluid. Medium settings see the average fall to 79 FPS, with a minimum of 68 FPS and a maximum of 91 FPS. High settings hit an average of 60 FPS, which is the threshold for smooth gameplay on many displays. Ultra settings bring the average down to 57 FPS, which is still playable but shows that the GPU is working harder.

At 4K, the system is clearly GPU-bound. Low settings average 75 FPS, which is surprisingly high for 4K and shows the CPU is not a limiting factor. Medium settings average 59 FPS, with a minimum of 50 FPS and a maximum of 67 FPS, which is a playable experience. High settings average 44 FPS, and Ultra settings average 42 FPS, both of which are below the ideal 60 FPS target and may require a variable refresh rate display to feel smooth. The narrow gap between High and Ultra at 4K (44 vs 42 FPS) suggests that the GPU is hitting a hard computational ceiling.

GPU Role

The AMD Radeon RX 6750 XT is a 12 GB GDDR6 card based on the RDNA 2.0 architecture. It has a boost clock of 2600 MHz and a memory bandwidth of 432.0 GB/s. Its 3DMark Steel Nomad DX12 score is 2548, and its Passmark G3D score is 20700. Its percentileVsAllGpus is 71, meaning it outperforms 71% of all GPUs in the database.

The GPU's role in this pairing is to handle the graphical rendering load, and the data shows it is the main bottleneck at higher resolutions. The 12 GB of VRAM is sufficient for 1080p and 1440p gaming, but at 4K with High or Ultra settings, the memory capacity and bandwidth may become a limiting factor. The fact that the 4K High and Ultra averages are within 2 FPS of each other (44 vs 42 FPS) strongly suggests that the GPU's compute units are saturated, and the VRAM is not the primary constraint in this specific scenario.

The GPU's nearest rival in the database is the AMD Radeon R9 M395X, which has an average score of 25891, a 0.5% delta from the RX 6750 XT's 26011. This is a surprising comparison, but it highlights that the RX 6750 XT's performance is not exceptional in the grand scheme of things. However, for this game, the data shows it can deliver a solid 60 FPS at 1440p with High settings, which is a realistic target for most users. The card's 40 ray accelerators are present, but the game's reliance on rasterization performance likely means these are not heavily utilized.
