Microsoft Flight Simulator

The Intel Core i5-14600KF paired with the Intel Arc B570 is a combination that places near the middle of the pack for Microsoft Flight Simulator, ranking 2406 out of 2996 tested combos. This pairing of a high-end 14-core CPU with a mid-range 10 GB GPU yields playable performance at lower resolutions but struggles significantly at 4K Ultra. The data shows a system that is heavily GPU-limited at higher settings, while the CPU provides ample headroom at lower resolutions.

CPU Role — cores, clocks, and how they relate to this game's results

The Intel Core i5-14600KF is a 14-core, 20-thread processor built on the Raptor Lake architecture, with a base clock of 3.50 GHz and a boost clock of 5.30 GHz. It features a substantial 24 MB of shared L3 cache and supports both DDR4 and DDR5 memory. This is a 125 W desktop part with an unlocked multiplier for overclocking, and it sits in the 90th percentile of all CPUs based on its average benchmark score of 49394. In synthetic tests, it scores 32544 in Cinebench R23 multi-core and 4594 in single-core, with a Geekbench multi-core score of 17085.

In Microsoft Flight Simulator, the CPU's role is most apparent at lower resolutions and settings where the GPU is not the primary bottleneck. At 1080p Low, the combo produces 86 FPS, which is the highest average recorded across all tested configurations. This suggests the i5-14600KF has enough processing power to feed the Arc B570 effectively when the graphical load is light. The CPU's strong single-core performance, evidenced by its 4594 Cinebench R23 single-core score, is particularly relevant for a flight simulator that relies heavily on simulation and physics calculations, which are typically single-threaded.

However, the data indicates that the CPU is not the limiting factor in most scenarios. When moving from 1080p Low to 1080p Ultra, the average FPS drops from 86 to 48, a 44% reduction. This steep decline is far more attributable to the GPU's workload than to CPU limitations. The i5-14600KF's nearest rivals in the CPU benchmark database include the AMD Ryzen 9 7900, which scores a nearly identical average (49228, a 0.3% difference), and the Intel Core Ultra 5 245, which is 0.8% slower. This places the i5-14600KF in a performance tier where it is unlikely to be the weak link in this specific game combo.

The core and thread count of the i5-14600KF is more than adequate for the game's demands. While the game may not fully utilize all 20 threads, the available processing power ensures that the CPU does not bottleneck the GPU at any of the tested settings. The benchmark results confirm this: the FPS scaling from Low to Ultra is consistent with a GPU-bound workload, meaning the CPU is delivering frames faster than the GPU can render them at higher graphical presets.

How This Combo Ranks — use comboRankInGame vs other tested combos

The combination of the Intel Core i5-14600KF and Intel Arc B570 achieves a combo rank of 2406 out of 2996 tested combinations in Microsoft Flight Simulator. This places it in the lower half of the database, which is a critical indicator of its overall performance ceiling. Given the CPU's strong benchmark scores, this rank reflects the limitations of the GPU rather than the processor.

The data suggests that the CPU is performing at a level that would allow for a much higher combo rank if paired with a more powerful GPU. The i5-14600KF's percentile of 90 versus the Arc B570's percentile of 65 highlights this disparity. The GPU is the bottleneck in this pairing, and the combo rank of 2406 is a direct consequence of the Arc B570's inability to keep up with the CPU's output at higher settings.

Compared to other combos in the database, this system is not competitive for high-refresh-rate play at 4K, but it is serviceable for 1080p gaming. The rank should be interpreted as a mid-to-low tier result for a flight simulator that is known to be demanding. While the CPU is a top-tier performer, the overall combo is dragged down by the GPU, resulting in a rank that does not reflect the processor's individual capabilities.

Resolution Scaling — how FPS drops from 1080p to 4K and what it says about the limiting component

The FPS scaling across resolutions clearly identifies the GPU as the limiting component in this system. At Low settings, the average FPS drops from 86 at 1080p to 69 at 1440p, and then to 51 at 4K. This is a 41% reduction from 1080p to 4K. At High settings, the drop is from 50 FPS at 1080p to 41 FPS at 1440p, and finally to 30 FPS at 4K, representing a 40% decrease.

This pattern is a textbook example of GPU-bound scaling. As the resolution increases, the number of pixels the GPU must render grows exponentially, and the FPS drops accordingly. If the CPU were the limiting factor, the FPS would remain relatively flat across resolutions, as the CPU's workload would be unchanged. The data shows that is not the case, confirming the CPU has significant headroom.

The most telling comparison is between 1080p Low and 4K Low. The FPS falls by 35 FPS (86 down to 51), which is a substantial loss that can only be attributed to the GPU's fill rate and memory bandwidth. The Arc B570 has a 160-bit memory bus and 380.0 GB/s of bandwidth, which is sufficient for 1080p but becomes a constraint at 4K. The data suggests that for a smooth 4K experience, this GPU is inadequate, as even Low settings yield only 51 FPS.

Measured FPS Breakdown — resolution by resolution, settings by settings, exact numbers

The measured FPS data provides a detailed picture of the system's performance across all tested configurations. At 1080p, the results are as follows: Low averages 86 FPS, Medium averages 67 FPS with a minimum of 57 and a maximum of 77, High averages 50 FPS, and Ultra averages 48 FPS. The gap between High and Ultra is notably small, only 2 FPS, which is an important detail for settings recommendations.

At 1440p, the performance drops noticeably. Low averages 69 FPS, Medium averages 54 FPS (minimum 46, maximum 62), High averages 41 FPS, and Ultra averages 39 FPS. The scaling from 1080p to 1440p is roughly a 20-25% reduction in FPS across all settings, which is consistent with the resolution's pixel count increase.

At 4K, the system struggles to maintain playable frame rates. Low averages 51 FPS, Medium averages 40 FPS (minimum 34, maximum 46), High averages 30 FPS, and Ultra averages 28 FPS. The drop from High to Ultra at 4K is only 2 FPS, mirroring the 1080p pattern, but the overall performance is below 60 FPS even at Low settings. The minimum FPS of 34 at 4K Medium indicates that there are moments of significant stutter, which can be particularly jarring in a flight simulator.

GPU Role — VRAM, clocks, and how they relate to this game's results

The Intel Arc B570 is a 10 GB GDDR6 graphics card based on the Xe2-HPG architecture, built on a 5 nm process at TSMC. It has a base and boost clock of 2500 MHz, with memory running at 2375 MHz (19 Gbps effective). The GPU features 2304 shading units, 144 TMUs, and 80 ROPs, along with 18 ray tracing cores. It delivers 11.52 TFLOPS of FP32 compute performance and has a texture rate of 360.0 GTexel/s.

The GPU's performance in this game is clearly the primary bottleneck. Its 65th percentile ranking among all GPUs, with an average benchmark score of 20556, places it in the mid-range of the market. Its nearest rivals include the NVIDIA GeForce RTX 3070 Mobile (0.1% faster) and the Intel Arc A750 (0.1% slower), which gives a sense of its relative standing. The 10 GB VRAM is not the limiting factor here, as even at 4K Ultra, the game does not appear to exceed this capacity, but the raw compute power is insufficient for high-resolution gaming.

The GPU's 380.0 GB/s memory bandwidth is a key constraint at 4K. The high-resolution textures and rendering demands of the game require significant bandwidth, and the B570's 160-bit bus width likely contributes to the steep FPS drop at 4K. The data shows that the GPU is capable of delivering 86 FPS at 1080p Low, indicating that it is not a weak part per se, but it is out of its depth at higher resolutions and settings in this specific simulation.

Settings Recommendations — which preset gives the best experience per the measured rows

Based on the measured FPS data, the optimal settings for this combo depend heavily on the user's target resolution and frame rate preference. For a 60 FPS experience, the only viable option is 1080p Low, which averages 86 FPS. This provides a significant performance buffer, ensuring smooth gameplay even in complex scenes. For users who prioritize visual quality over frame rate, the 1080p Medium preset, averaging 67 FPS, is a strong choice, offering a substantial improvement in visuals over Low while still maintaining a comfortable frame rate above 60 FPS.

At 1440p, the system cannot consistently achieve 60 FPS. The Low preset averages 69 FPS, which is playable, but the Medium preset drops to 54 FPS. Given the small 2 FPS difference between High (41 FPS) and Ultra (39 FPS) at this resolution, there is no reason to use Ultra over High; the visual gains are minimal, and the performance cost is not worth it. The Medium preset at 1440p, with a minimum of 46 FPS, may be acceptable for some users, but it is borderline for a smooth experience.

At 4K, the system is not recommended for any preset if a stable 60 FPS is desired. The Low preset averages 51 FPS, which is below the 60 FPS target. The Medium preset averages 40 FPS, and High and Ultra are both below 30 FPS. The data suggests that the best experience at 4K is to use the Low preset, as it provides the highest frame rate, but even this is not ideal. For the best overall experience, the 1080p Medium preset offers the best balance of visual fidelity and performance, with an average of 67 FPS and a minimum of 57 FPS, ensuring a mostly stable and enjoyable flight simulation experience.
