Microsoft Flight Simulator

Microsoft Flight Simulator is a demanding title, and the combination of the Intel Core Ultra 7 270K Plus and AMD Radeon RX 6600 XT produces a playable, but not universally smooth, experience. The data indicates this pairing is firmly GPU-limited at higher resolutions, with the CPU providing ample headroom to push frame rates at 1080p. The measured results show a system that can hit 60 FPS at 4K only on Low settings, while 1080p Ultra remains below 60 FPS, highlighting the GPU as the primary bottleneck for this flight sim.

Resolution Scaling

The frame rate data shows a clear and consistent pattern: performance degrades significantly as resolution increases, which points directly at the GPU as the limiting component. At 1080p, the average frame rates are 101 FPS on Low, 78 FPS on Medium, 59 FPS on High, and 56 FPS on Ultra. Moving to 1440p, these figures drop to 81 FPS on Low, 63 FPS on Medium, 47 FPS on High, and 45 FPS on Ultra. At 4K, the averages fall further to 60 FPS on Low, 47 FPS on Medium, 35 FPS on High, and 33 FPS on Ultra.

The scaling from 1080p to 4K is steep. For instance, on Low settings, the average frame rate drops from 101 FPS at 1080p to 60 FPS at 4K, a reduction of 41 FPS. On Medium settings, the drop is from 78 FPS to 47 FPS, a 31 FPS reduction. This pattern is typical of a system where the graphics card's rendering throughput is the constraint. As the pixel count rises, the GPU must work harder to fill each frame, and the frame rate falls proportionally. The CPU, with its high core count and boost clock, is not shown to be holding the system back in these scenarios.

The fact that the 4K Low setting still achieves an average of 60 FPS, while 1440p Ultra only manages 45 FPS, further emphasizes the GPU's dominance. The difference between Low and Ultra at any given resolution is substantial. At 1080p, the gap between Low and Ultra is 45 FPS, while at 4K, the gap narrows to 27 FPS. This narrowing suggests that at 4K, the GPU is so saturated that even reducing settings has a smaller absolute impact on the frame rate than at lower resolutions. The data strongly suggests that for a smoother experience at higher resolutions, the graphics card is the component that would need to be upgraded.

GPU Role

The AMD Radeon RX 6600 XT, with its 8 GB of GDDR6 memory on a 128-bit bus, is the central figure in this system's performance profile. The memory provides a bandwidth of 256.0 GB/s, and the card's boost clock is rated at 2589 MHz. In the context of Microsoft Flight Simulator, the benchmark results indicate that the GPU's capabilities are the deciding factor for frame rates at 1440p and 4K. The card's performance percentile is 70, meaning it outperforms 70% of all GPUs in the database, which places it as a mid-range part.

The VRAM capacity of 8 GB is a key consideration. The measured data shows that at 4K Ultra, the average frame rate is 33 FPS, which is the lowest result in the set. While the frame rate is low, the data does not explicitly state that VRAM capacity is the cause. However, for a flight simulator that renders vast landscapes and detailed aircraft, the 8 GB frame buffer could be a limiting factor at higher resolutions and settings. The data shows a clear drop from 47 FPS at 4K Medium to 35 FPS at 4K High, and further to 33 FPS at 4K Ultra. This suggests that the more demanding settings are taxing the GPU heavily.

The GPU's nearest rival, the NVIDIA GeForce RTX 2080 SUPER, has an average benchmark score that is only 1.1% higher. This is a notable data point, as the RTX 2080 SUPER is a card from a higher tier in its generation. The RX 6600 XT's performance, therefore, is competitive with that older, higher-end card in general compute benchmarks. However, in this specific game, the measured FPS tells the real story. The GPU's 10.60 TFLOPS of FP32 performance and 165.7 GPixel/s pixel rate are the raw numbers that translate into the 33-101 FPS range seen across the test matrix. The data indicates that for this game, the GPU is the bottleneck, especially as resolution and settings are increased.

CPU Role

The Intel Core Ultra 7 270K Plus is a high-end desktop processor with 24 cores and 24 threads, a boost clock of 5.50 GHz, and a TDP of 125 W. Its benchmark scores are impressive, with a Cinebench R23 multi-core score of 44253 and a single-core score of 2439. The CPU's performance percentile is 96, indicating it is faster than 96% of all CPUs in the database. This is a powerful part, and the data suggests it is not the limiting factor in this gaming scenario.

In Microsoft Flight Simulator, which is known for being demanding on both the CPU and GPU, the measured FPS data shows that the CPU has significant headroom. At 1080p Low, the system achieves 101 FPS, which is the highest average in the entire dataset. If the CPU were the bottleneck, we would expect to see this frame rate cap across multiple resolutions. However, the FPS drops consistently as resolution increases, which is a hallmark of a GPU-limited system. The CPU is likely able to feed the GPU with enough data to keep it busy, but at higher resolutions, the GPU's rendering workload becomes the primary constraint.

The CPU's nearest rival, the Intel Xeon 6520P, has an identical average benchmark score with a deltaPct of 0, while the AMD EPYC 4564P is 1.5% slower. This shows that the Core Ultra 7 270K Plus is in the top tier of processor performance. For this game, the high single-core performance, as evidenced by the Cinebench R23 single-core score of 2439, is likely more important than the multi-core might. Flight simulators often rely heavily on single-threaded performance for game logic and physics. The data indicates that the CPU does not prevent the system from reaching its maximum potential with this GPU; instead, the GPU's limits are what define the frame rates.

How This Combo Ranks

The combined performance of the Intel Core Ultra 7 270K Plus and AMD Radeon RX 6600 XT in Microsoft Flight Simulator is ranked 2058 out of 2996 tested combos. This places the system in the lower third of all tested configurations. This ranking is a direct result of the GPU's performance, as the CPU is a top-tier part. The combo's rank is significantly lower than the individual component percentiles would suggest, which reinforces the conclusion that the GPU is the bottleneck.

The CPU is in the 96th percentile, and the GPU is in the 70th percentile. A combination of two parts that are at the 70th percentile or higher should, in theory, rank higher than 2058 out of 2996. The fact that it does not indicates that the pairing is imbalanced for this specific game. The data shows that the GPU is holding back what is otherwise a very capable processor. In other words, the Core Ultra 7 270K Plus is not being fully utilized in this configuration. The measured FPS data supports this, as the system struggles to maintain 60 FPS at 1080p Ultra, a task that a high-end CPU should be able to handle if paired with a more powerful GPU. The combo's rank of 2058 out of 2996 is a clear signal that for Microsoft Flight Simulator, the graphics card is the weak link in this chain.

Measured FPS Breakdown

The measured FPS data provides a complete picture of the system's performance across all settings and resolutions. At 1920x1080, the system delivers an average of 101 FPS on Low, 78 FPS on Medium, 59 FPS on High, and 56 FPS on Ultra. The Medium setting has a min FPS of 66 and a max FPS of 90, showing some variance but a generally stable experience. The 1080p results are the best of the dataset, with only the Low and Medium settings achieving an average above 60 FPS.

At 2560x1440, the averages are 81 FPS on Low, 63 FPS on Medium, 47 FPS on High, and 45 FPS on Ultra. The Medium setting here shows a min FPS of 54 and a max of 73. This is a playable experience on Medium, but High and Ultra settings fall below the 60 FPS target. At 3840x2160, the averages are 60 FPS on Low, 47 FPS on Medium, 35 FPS on High, and 33 FPS on Ultra. The Medium setting at 4K has a min FPS of 40 and a max of 54. This data shows that 4K gaming is only viable at Low settings, and even then, it is right at the 60 FPS mark.

The pattern is consistent: for every resolution, the average FPS decreases as settings increase. The delta between Low and Ultra is 45 FPS at 1080p, 36 FPS at 1440p, and 27 FPS at 4K. This indicates that at 4K, the GPU is so heavily loaded that the difference between Low and Ultra settings has a smaller absolute impact on frame rate. The data provides a clear roadmap for what to expect from this hardware combination. For example, a user wanting a smooth 60 FPS experience would need to be at 1080p Medium or Low, or 1440p Low. At 4K, only the Low preset achieves 60 FPS on average.

Settings Recommendations

Based on the measured FPS data, the best experience for this combination of Intel Core Ultra 7 270K Plus and AMD Radeon RX 6600 XT depends heavily on the user's target resolution and preference for frame rate versus visual fidelity. The data shows that no single preset delivers a perfect 60 FPS at all resolutions. The goal is to find the highest settings that maintain a playable frame rate, which is generally considered to be at least 60 FPS for a smooth experience.

For 1080p gaming, the Medium preset is the sweet spot. It achieves an average of 78 FPS, with a min FPS of 66, ensuring that the frame rate stays above 60 FPS even in demanding scenes. The High preset drops to an average of 59 FPS, which is just below the 60 FPS target, and the Ultra preset is at 56 FPS. Therefore, Medium offers the best balance of visual quality and performance at 1080p, providing a comfortable margin above the 60 FPS threshold. If a user prioritizes visual fidelity over frame rate, High is a viable option, but they must accept an average slightly below 60 FPS.

At 1440p, the Medium preset is again the recommended choice. It delivers an average of 63 FPS, with a min FPS of 54. While the average is above 60, the min FPS indicates that there will be some dips below that target. The Low preset is the only other option that averages above 60 FPS (81 FPS). High and Ultra averages of 47 and 45 FPS, respectively, are not ideal for a smooth experience. For a more stable frame rate at 1440p, choosing Low would be the safest option, but Medium provides a better balance of quality and performance, with the understanding that occasional drops below 60 FPS will occur.

For 4K gaming, the options are more limited. The Low preset is the only one that achieves an average of 60 FPS. The Medium preset averages 47 FPS, with a min of 40, which is playable but not consistently smooth. High and Ultra averages of 35 and 33 FPS are not recommended for a good experience. Therefore, at 4K, the Low preset is the only way to achieve a 60 FPS average. The data shows that this hardware combination is not suited for high-fidelity 4K gaming in Microsoft Flight Simulator. The recommendation is to play at 4K Low if 60 FPS is the target, or to drop to a lower resolution to use higher quality presets. Overall, the best experience across all resolutions is on the Medium preset, which provides a good balance of visual detail and frame rate, especially at 1080p and 1440p.
