Microsoft Flight Simulator

The benchmark data for Microsoft Flight Simulator, paired with the Intel Core i5-14600K and AMD Radeon RX 5700 XT, reveals a configuration that is heavily constrained by the graphics card, particularly at higher resolutions. The measurements provide a clear picture of a system that is capable of smooth performance at 1080p, but struggles to maintain high frame rates at 4K, with the CPU showing significant headroom.

Resolution Scaling

The progression from 1080p to 4K demonstrates a classic GPU-bound scenario. At 1080p with Low settings, the combo achieves an average of 101.6 FPS, which drops to 78.8 FPS at 1440p, and further to 58 FPS at 4K. This represents a 42.5% reduction in frame rate when moving from 1080p to 4K at Low settings, a steep decline that indicates the rendering load is scaling heavily with pixel count.

The pattern is consistent across all settings. At High settings, the average FPS falls from 58.1 at 1080p to 46.2 at 1440p and 33.5 at 4K. The gap between 1440p and 4K is particularly telling: a 27.5% drop in performance at High settings. This substantial decrease points directly to the GPU as the limiting component, as the Radeon RX 5700 XT’s 8 GB of GDDR6 memory and 448.0 GB/s bandwidth become exhausted as resolution increases.

Interestingly, the scaling between 1080p and 1440p is less severe, with roughly a 20% performance loss across most settings. This suggests that at 1080p, the CPU is still contributing to the frame rate, but once the resolution increases, the GPU’s fill rate and memory bandwidth become the primary bottlenecks. The data indicates that this combo is best suited for 1080p gaming, where it can deliver playable frame rates even at Ultra settings.

How This Combo Ranks

Within the database of tested configurations for Microsoft Flight Simulator, this specific pairing of the Intel Core i5-14600K and AMD Radeon RX 5700 XT holds a rank of 1373 out of 1795 tested combos. This places it in the lower 25th percentile of all tested systems, suggesting that while it is functional, it is far from optimal for this demanding simulator.

The CPU itself is not the limiting factor in this ranking. The Core i5-14600K sits in the 93rd percentile among all CPUs tested, with an average benchmark score of 49166. Its nearest rivals include the AMD Ryzen 9 5950X, which scores 49062 (a delta of 0.2%), and the Intel Core i5-14600KF, which scores 49367 (a delta of -0.4%). These margins are negligible, indicating that the 14600K is a high-performing processor that should not bottleneck most games.

However, the GPU tells a different story. The Radeon RX 5700 XT is in the 68th percentile among all GPUs, with an average score of 24731. Its nearest rivals include the NVIDIA RTX A5000 Mobile (24763, delta -0.1%) and the Intel Arc A350M (24647, delta 0.3%). The relatively low ranking of the combo suggests that the GPU’s performance is dragging down the overall experience, as the CPU has significant headroom that the GPU cannot utilize.

GPU Role

The AMD Radeon RX 5700 XT, built on the RDNA 1.0 architecture with a 7 nm process, provides the graphical muscle for this combo. Its 8 GB of GDDR6 memory on a 256-bit bus delivers 448.0 GB/s of bandwidth, which is adequate for 1080p but becomes a limiting factor at higher resolutions. The GPU’s boost clock of 1905 MHz and game clock of 1755 MHz are respectable for its generation, but the data shows that this hardware is struggling with the demands of Microsoft Flight Simulator at 4K.

The GPU’s FP32 performance of 9.754 TFLOPS and texture rate of 304.8 GTexel/s are moderate figures, but they are insufficient for the heavy draw calls and complex scenery in this simulator. The benchmark results show that at 4K Ultra settings, the combo can only manage 33.5 FPS, which is below the threshold for smooth gameplay. Even at 4K Low settings, the 58 FPS average is playable but not ideal.

The GPU’s VRAM capacity of 8 GB is also a concern. At 4K resolution, the texture data required by Microsoft Flight Simulator can easily exceed this amount, leading to potential stuttering or texture popping. The fact that the 4K High and Ultra settings both produce 33.5 FPS suggests that the GPU is hitting a hard performance ceiling, likely due to memory bandwidth limitations rather than compute capacity.

Measured FPS Breakdown

The complete set of measured frame rates provides a detailed view of this combo’s capabilities across different resolutions and settings.

At 1920x1080, the combo performs admirably:

• Low: 101.6 FPS
• Medium: 75.4 FPS
• High: 58.1 FPS
• Ultra: 55.8 FPS

The 1080p results show a clear progression, with Low settings nearly doubling the frame rate of Ultra. The difference between High and Ultra is minimal (58.1 vs 55.8 FPS), suggesting that the Ultra preset adds graphical features that have a negligible impact on performance at this resolution.

At 2560x1440, the performance drops noticeably:

• Low: 78.8 FPS
• Medium: 61.8 FPS
• High: 46.2 FPS
• Ultra: 43.6 FPS

The 1440p results show a more pronounced drop from Low to Medium (78.8 to 61.8 FPS), indicating that the GPU is starting to struggle with the increased pixel count. The gap between High and Ultra narrows further (46.2 vs 43.6 FPS), suggesting that both presets are hitting similar GPU limits.

At 3840x2160, the performance is severely constrained:

• Low: 58 FPS
• Medium: 42.5 FPS
• High: 33.5 FPS
• Ultra: 33.5 FPS

The 4K results are telling. Low settings can still achieve 58 FPS, but Medium drops to 42.5 FPS, and both High and Ultra are locked at 33.5 FPS. This indicates that the GPU is completely saturated at High settings, and the Ultra preset offers no additional performance cost because the hardware is already maxed out.

FAQ

Q: What is the best resolution for this combo in Microsoft Flight Simulator?

A: The data shows that 1920x1080 is the optimal resolution. At 1080p Low settings, the combo achieves 101.6 FPS, and even at Ultra settings, it maintains 55.8 FPS, which is playable. At 1440p and 4K, the frame rates drop significantly, with 4K Ultra yielding only 33.5 FPS.

Q: How does the CPU compare to its nearest rivals?

A: The Intel Core i5-14600K has an average benchmark score of 49166, placing it in the 93rd percentile. It is essentially tied with the AMD Ryzen 9 5950X (49062, delta 0.2%) and slightly behind the Intel Core i5-14600KF (49367, delta -0.4%). These differences are negligible in real-world performance.

Q: Is the GPU the bottleneck in this system?

A: Yes, the data strongly suggests this. The CPU is in the 93rd percentile, while the GPU is in the 68th percentile. At 4K, the frame rates for High and Ultra settings are identical (33.5 FPS), indicating the GPU is fully saturated and cannot render faster regardless of the CPU’s capability.

Q: What is the GPU’s memory configuration?

A: The AMD Radeon RX 5700 XT has 8 GB of GDDR6 memory on a 256-bit bus, with a bandwidth of 448.0 GB/s. The memory clock is 1750 MHz, which translates to 14 Gbps effective. This configuration is sufficient for 1080p but limits performance at higher resolutions.

Q: How does this combo rank among all tested configurations?

A: It ranks 1373 out of 1795 tested combos for Microsoft Flight Simulator. This places it in the lower quartile, primarily due to the GPU’s performance limitations relative to the CPU’s high capability.

Q: What are the GPU’s clock speeds?

A: The base clock is 1605 MHz, the boost clock is 1905 MHz, and the game clock is 1755 MHz. These clocks are consistent with the GPU’s generation, but the benchmark results show they are not enough to maintain high frame rates at 4K resolution in this simulator.
