# How This Combo Ranks

The Intel Core i5-14600KF paired with the AMD Radeon RX 9070 lands at rank 569 out of 1795 tested combos in Microsoft Flight Simulator, placing it in the upper third of all configurations. This is a strong result for a flight simulator, where sustained frame rates matter more than peak performance. The combo outperforms roughly 68% of all tested pairings, and the data shows it is well-suited for the game's demanding rendering of terrain and weather systems.

What makes this ranking notable is the balance between the two components. The CPU sits in the 93rd percentile among all processors tested, while the GPU ranks in the 79th percentile among all graphics cards. In a simulation title like this, where CPU physics and draw-call processing often bottleneck GPU output, having a CPU that outperforms the GPU in relative standing is advantageous. The measured frame rates confirm this synergy, with the combo delivering playable performance even at maximum settings across all tested resolutions.

# CPU Role

The Intel Core i5-14600KF brings 14 cores and 20 threads to the simulation, running at a base clock of 3.50 GHz and boosting up to 5.30 GHz. This configuration is built on the Raptor Lake architecture using a 10 nm process, with 24 MB of shared L3 cache and 2 MB of L2 cache per core. For Microsoft Flight Simulator, the high boost clock is critical, because the game's simulation loop—which handles aircraft systems, weather modeling, and terrain loading—relies heavily on single-threaded performance.

Benchmark data supports this: the CPU scores 4643 in Cinebench R23 single-core and 2778 in Geekbench single-core, both strong results that translate directly to the game's main thread. Multi-core performance is also robust, with a Cinebench R23 multi-core score of 32889 and a Passmark multithread score of 38697. This matters for Flight Simulator's background tasks, such as loading scenery tiles and processing AI traffic, which can offload work to additional threads.

Relative to its nearest rivals, the i5-14600KF is essentially tied with the Intel Core i5-14600K, showing a delta of 0.4% in average benchmark score. It also edges out the AMD Ryzen 9 5950X by 0.6% and trails the AMD EPYC 4345P by just 0.5%. This means the CPU is not the limiting factor in this combo; it has ample headroom to feed the RX 9070 in most scenarios.

# FAQ

Q: Does this combo achieve 60 FPS at 4K in Microsoft Flight Simulator?

A: At 4K with High settings, the average frame rate is 52.6 FPS, which falls short of 60. However, at 4K Medium, the average rises to 68.1 FPS, and at 4K Low, it reaches 92.3 FPS, so 60 FPS is attainable by adjusting settings.

Q: How does the CPU compare to its closest rival, the Intel Core i5-14600K?

A: The i5-14600KF scores 49367 in average benchmark, which is 0.4% higher than the i5-14600K's 49166. This is a negligible difference, so performance in-game should be virtually identical.

Q: What is the best resolution for high refresh rate play?

A: At 1080p with Low settings, the combo averages 153.4 FPS, which supports high refresh rate monitors. Even at 1440p Low, it hits 125.9 FPS, and at 1080p Medium, it maintains 122.9 FPS.

Q: Is the GPU's VRAM sufficient for this game at 4K Ultra?

A: The RX 9070 has 16 GB of GDDR6 memory on a 256-bit bus, delivering 644.6 GB/s bandwidth. At 4K Ultra, the combo averages 50.6 FPS, indicating the VRAM is adequate for the game's highest settings.

Q: How does the GPU rank against its nearest rival, the NVIDIA A2?

A: The RX 9070 scores 34780 in average benchmark, which is 0.2% lower than the NVIDIA A2's 34866. This places them in a dead heat, though the RX 9070 has significantly more gaming-focused features.

Q: Can this combo handle 1440p Ultra?

A: Yes, at 1440p Ultra, the average frame rate is 70.2 FPS, which is above the 60 FPS threshold for smooth gameplay. The 1440p High setting pushes this to 74.8 FPS.

# Measured FPS Breakdown

At 1080p, the combo delivers its highest frame rates. Low settings produce an average of 153.4 FPS, while Medium drops to 122.9 FPS. High settings yield 88.7 FPS, and Ultra brings the average down to 84.6 FPS. The gap between Low and Ultra is 68.8 FPS, showing that the GPU has significant headroom at this resolution but the game's settings scale heavily with graphical load.

Moving to 1440p, frame rates remain strong. Low settings average 125.9 FPS, Medium drops to 99.2 FPS, and High reaches 74.8 FPS. Ultra settings produce 70.2 FPS, which is only 4.6 FPS lower than High. This suggests that the jump from High to Ultra at 1440p is relatively modest in performance cost, making Ultra a viable option.

At 4K, the combo begins to show its limits. Low settings average 92.3 FPS, which is still highly playable. Medium drops to 68.1 FPS, and High falls to 52.6 FPS. Ultra settings produce 50.6 FPS, which is below the 60 FPS target but still within a range that many players find acceptable for a flight simulator. The delta between 1080p Low and 4K Low is 61.1 FPS, indicating that resolution scaling has a substantial impact on this configuration.

# Resolution Scaling

The frame rate drop from 1080p to 4K reveals a clear GPU-bound trend at higher resolutions, but the CPU remains a strong partner throughout. At Low settings, the combo drops from 153.4 FPS at 1080p to 92.3 FPS at 4K, a reduction of 39.8%. At Medium settings, the drop is from 122.9 FPS to 68.1 FPS, a 44.6% reduction. High settings fall from 88.7 FPS to 52.6 FPS, a 40.7% drop, and Ultra goes from 84.6 FPS to 50.6 FPS, a 40.2% decrease.

These percentages are remarkably consistent, hovering around 40% across all settings. This uniformity suggests that the GPU is the primary scaling factor, as its workload scales linearly with pixel count. The CPU's role remains stable, because Flight Simulator's simulation thread is not resolution-dependent. The data indicates that the i5-14600KF can maintain its thread performance even when the GPU is taxed at 4K, preventing it from becoming a bottleneck at lower resolutions.

The limiting component shifts with resolution. At 1080p, the GPU is clearly the constraint, as evidenced by the large frame rate differences between settings. At 4K, the GPU is still the limiting factor, but the margins narrow, and the CPU's high single-thread score ensures that it does not exacerbate the drop.

# Settings Recommendations

For the best balance of visual fidelity and frame rate, Medium settings at 1440p are the sweet spot. The combo averages 99.2 FPS at this configuration, which is well above the 60 FPS threshold while still offering enhanced textures and lighting over Low. Players prioritizing smoothness over visuals should consider 1440p Low, which delivers 125.9 FPS, or 1080p Medium at 122.9 FPS.

At 4K, Medium settings are the recommended choice, with an average of 68.1 FPS. This stays above 60 FPS and provides a significant visual upgrade over Low, which runs at 92.3 FPS but sacrifices detail. High settings at 4K dip to 52.6 FPS, which may be acceptable for simulation enthusiasts who prioritize realism over frame rate, but the data shows that Medium offers the better experience for most users.

For maximum visual quality on a 1440p monitor, Ultra settings at 70.2 FPS are viable. The 4.6 FPS difference between High and Ultra at this resolution is small enough to justify the extra visual detail. At 1080p, Ultra runs at 84.6 FPS, which is also smooth, but the gains over High are less pronounced given the lower pixel count.

# GPU Role

The AMD Radeon RX 9070 is built on the RDNA 4.0 architecture with a Navi 48 chip manufactured on a 4 nm process. It features 3584 shading units, 224 texture mapping units, and 128 render output units, with 56 ray tracing cores. The GPU's boost clock reaches 2520 MHz, with a game clock of 2070 MHz, and it operates at a 1330 MHz base. Memory consists of 16 GB of GDDR6 on a 256-bit bus, providing 644.6 GB/s of bandwidth.

In Microsoft Flight Simulator, the GPU's role is to render the vast draw distances and dense geometry typical of flight simulators. The 16 GB VRAM is particularly important, as the game loads large texture sets for terrain and aircraft. The 3DMark Steel Nomad DX12 score of 6290 indicates strong rasterization performance, and the Passmark G3D score of 25381 places it in the 79th percentile of all GPUs.

Relative to its nearest rivals, the RX 9070 is essentially tied with the NVIDIA A2, showing a delta of -0.2% in average benchmark score. It also outperforms the AMD Radeon HD 7970 by 0.7% and the AMD Radeon PRO W6400 by 0.8%. The GPU's 36.13 TFLOPS of FP32 compute and 564.5 GTexel/s texture rate are more than sufficient for the game's demands, though the measured frame rates show that it is the primary bottleneck at 4K Ultra, where it averages 50.6 FPS.
