Microsoft Flight Simulator

Microsoft Flight Simulator presents one of the most demanding workloads in the benchmark database, and the pairing of the Intel Core i7-14700KF with the AMD Radeon RX 570 illustrates a severe imbalance between processing capability and rendering throughput. The measured FPS data shows a system that is overwhelmingly GPU-limited across all tested resolutions and settings, with the CPU's substantial compute resources left largely underutilized. This analysis examines the resolution scaling, component roles, and overall ranking of this specific combination based solely on the provided measurement data.

Resolution Scaling

The measured FPS data reveals a predictable but steep decline in performance as resolution increases, confirming the AMD Radeon RX 570 as the primary bottleneck. At 1920x1080 with Low settings, the system achieves an average of 50 FPS, which drops to 37.8 FPS at 2560x1440 and further to 30.6 FPS at 3840x2160. This represents a 24.4% reduction from 1080p to 1440p and a 38.8% reduction from 1080p to 4K, illustrating how pixel count directly taxes the GPU's fill rate and memory bandwidth.

The scaling pattern across settings at each resolution is telling. At 1080p, moving from Low to Medium reduces the average from 50 FPS to 36.4 FPS, a 27.2% penalty, while High drops it to 30.8 FPS and Ultra to 27.9 FPS. The gap between Medium and High is 15.4%, but the gap between High and Ultra is only 9.4%, suggesting diminishing returns from the highest preset. At 1440p, the same progression yields 37.8, 32.8, 23.9, and 23.5 FPS for Low, Medium, High, and Ultra respectively, showing a more dramatic collapse between Medium and High at 27.1%.

The 4K results are uniformly below playable thresholds. Ultra at 3840x2160 averages 14.6 FPS, High averages 18.7 FPS, and Medium averages 20.7 FPS. Even the Low preset at 4K only reaches 30.6 FPS, which is marginal for a flight simulator where smooth panning is essential. The data indicates that this combination is not viable for 4K gaming under any preset, as the GPU's 4 GB GDDR5 memory and 224.0 GB/s bandwidth are insufficient for the texture and geometry loads typical of this resolution.

CPU Role

The Intel Core i7-14700KF is a 20-core, 28-thread processor based on the Raptor Lake architecture, with a base clock of 3.40 GHz and a boost clock of 5.60 GHz. Its benchmark scores place it in the 96th percentile of all CPUs tested, with a Cinebench R23 multi-core score of 44557 and a single-core score of 6290. This is a high-end desktop part designed for heavy multi-threaded workloads, and its synthetic performance is impressive on its own terms.

However, in Microsoft Flight Simulator, the CPU's role is largely secondary due to the GPU bottleneck. The measured FPS data shows no meaningful variation that could be attributed to CPU performance differences across the tested settings. For example, at 1080p Low, the system produces 50 FPS, but at 1080p Ultra it produces 27.9 FPS. If the CPU were the limiting factor, we would expect the FPS to remain relatively constant regardless of GPU settings, which is not the case. The data clearly shows that the RX 570's rendering limits cap the frame rate well before the i7-14700KF's processing capacity is exhausted.

The CPU's nearest rivals in the database include the Intel Core i7-14700K with a deltaPct of 0, the AMD EPYC 9115 at 0.3% higher average score, and the AMD Ryzen 9 9950X at 0.4% lower. These differences are negligible in real-world gaming terms, and none of these CPUs would change the outcome here. The i7-14700KF's 33 MB of shared L3 cache and dual-channel memory support for DDR4 and DDR5 are architectural strengths, but they do not manifest in higher FPS when the GPU is the constraining component.

GPU Role

The AMD Radeon RX 570 is a legacy Polaris 20 part from the RX 500 generation, built on a 14 nm process. It features 2048 shading units, 128 texture mapping units, and 32 ROPs, with a base clock of 1168 MHz and a boost clock of 1244 MHz. Its 4 GB of GDDR5 memory on a 256-bit bus provides 224.0 GB/s of bandwidth, which is modest by modern standards. The GPU's average benchmark score of 30158 places it in the 74th percentile of all GPUs, but its nearest rivals include the NVIDIA GeForce RTX 5060 and AMD Radeon RX 7700 XT, both within 0.2% deltaPct, which is surprising given the age difference.

In this game, the RX 570's limitations are stark. The 4 GB VRAM is likely a significant constraint at higher resolutions and settings, as Microsoft Flight Simulator is known for large texture sets. The measured FPS at 4K Ultra of 14.6 FPS suggests that the GPU is both bandwidth-limited and capacity-limited. The FP32 performance of 5.095 TFLOPS is insufficient for the complex shading and post-processing effects in this title, and the lack of dedicated ray tracing cores means any such effects would be handled through compute shaders, further reducing performance.

The GPU's power draw is rated at 150 W, with a suggested PSU of 450 W, but these figures are not directly relevant to the measured FPS. What matters is that the RX 570 is operating far outside its comfort zone in this game, even at 1080p. The 1080p Low average of 50 FPS is the only result that approaches a smooth experience, and it still falls short of the 60 FPS target many players prefer for flight simulation.

How This Combo Ranks

The combination of the Intel Core i7-14700KF and AMD Radeon RX 570 ranks 1691 out of 1795 tested combos in Microsoft Flight Simulator, placing it in the bottom 5.8% of all configurations. This is a remarkably low ranking given the CPU's elite status, and it directly reflects the GPU's inability to keep pace. The data shows that the i7-14700KF's 96th percentile CPU performance is completely wasted when paired with a GPU that sits in the 74th percentile but performs far worse in this specific title.

The ranking disparity is instructive. The CPU alone outperforms 96% of all processors in the database, yet the combo as a whole underperforms 94.2% of all tested combinations. This indicates that the RX 570 is not just a minor bottleneck but a severe one, dragging the entire system down to levels that are barely playable at 1080p Low settings. The deltaPct comparisons for the GPU show it is statistically tied with the RTX 5060 and RX 7700 XT in average benchmarks, but those GPUs would likely perform far better in this game due to newer architectures and higher memory bandwidth.

For context, the CPU's nearest rivals all have average scores within 1.3% of the i7-14700KF, meaning any of those processors would produce identical FPS in this configuration. The limiting factor is unambiguously the GPU, and the combo rank reflects this. Users with this pairing would see no benefit from upgrading the CPU alone; the RX 570 must be replaced to achieve meaningful performance gains.

Settings Recommendations

Based on the measured FPS rows, the only preset that provides a consistently playable experience is 1920x1080 with Low settings, which averages 50 FPS. This is the sole configuration that exceeds 30 FPS, and it does so by a comfortable margin. At 1080p Medium, the average drops to 36.4 FPS, which is still acceptable for a flight simulator but leaves little headroom for complex scenes with dense terrain or weather effects.

For users who prioritize visual fidelity over smoothness, 1080p High offers 30.8 FPS, which is borderline but may be acceptable for non-action-oriented flight. The 1080p Ultra preset at 27.9 FPS is below the 30 FPS threshold and is not recommended. At 1440p, the Low preset achieves 37.8 FPS, which might tempt some users, but the Medium preset at 32.8 FPS and High at 23.9 FPS show how quickly performance degrades. The 4K resolution is not viable under any preset, with the best case being Low at 30.6 FPS, which is still marginal and likely to stutter in busy airspace.

The data suggests that 1080p Low is the sweet spot for this combo, offering a 37.4% improvement over 1080p Medium and a 62.3% improvement over 1080p High. Users who are willing to accept lower visual quality will get the most consistent frame rates. Alternatively, 1080p Medium provides a 17.8% FPS increase over High, making it a reasonable middle ground for those who want better graphics without dropping below 30 FPS.
