Microsoft Flight Simulator

The Intel Core Ultra 5 235 paired with the Intel Arc B580 occupies the 2,788th position out of 3,714 tested combinations for Microsoft Flight Simulator, placing it in the lower-middle segment of the overall performance distribution. This rank indicates that while the hardware is functional, it sits closer to the bottom quartile of all possible pairings, meaning users should temper expectations for high-end visual fidelity. The benchmark data is measured, not estimated, which lends credibility to the specific frame rates observed across resolutions and presets. With a playable threshold of 60 FPS, the combination manages to clear this bar only at 1440p and 1080p on Medium settings, while 4K remains entirely out of reach for smooth gameplay.

How This Combo Ranks

The combo’s rank of 2,788 out of 3,714 tested pairs places it at roughly the 75th percentile from the top, meaning about one in four tested configurations performs worse. However, this does not tell the whole story, because Microsoft Flight Simulator is notoriously demanding on both CPU and GPU resources. The Intel Core Ultra 5 235 carries a percentile rank of 89 among all CPUs, indicating it is a strong processor in isolation, while the Intel Arc B580 sits at the 68th percentile among GPUs. The gap between these two percentiles suggests the GPU is the more limiting factor in this pairing, which aligns with the observed frame rates that scale heavily with resolution and preset changes.

Looking at the measured FPS data, the combination shows a clear pattern: at 1080p Low, the system achieves 97 FPS average, which drops to 76 FPS at Medium, 57 FPS at High, and 54 FPS at Ultra. At 1440p, the numbers fall to 78 FPS Low, 61 FPS Medium, 46 FPS High, and 44 FPS Ultra. At 4K, the averages are 58 FPS Low, 45 FPS Medium, 34 FPS High, and 32 FPS Ultra. The percentile rank of 68 for the GPU relative to the CPU’s 89 suggests that the Arc B580 is not able to fully leverage the processing power available, creating a bottleneck that becomes more pronounced as resolution increases. This is typical for flight simulators, where draw distances and terrain detail place heavy loads on the graphics pipeline.

FAQ

Q: Does the system ever exceed 60 FPS at 4K resolution?

A: No. At 3840x2160, the highest recorded average is 58 FPS on Low settings, which is the only preset that comes close to the threshold. All other presets at 4K average between 32 and 45 FPS, with Medium showing a minimum of 38 FPS and maximum of 52 FPS.

CPU and GPU Roles

The benchmark results reveal a clear division of labor between the Intel Core Ultra 5 235 and the Intel Arc B580 across the tested resolutions. At 1080p, the system is relatively balanced, with FPS ranging from 54 at Ultra to 97 at Low. The transition from Low to Medium at 1080p costs 21 FPS (97 to 76), while moving from Medium to High costs another 19 FPS (76 to 57), and High to Ultra costs only 3 FPS (57 to 54). This pattern suggests that the CPU can feed the GPU adequately at lower presets, but the GPU begins to struggle as settings increase.

At 1440p, the scaling becomes more pronounced. Low averages 78 FPS, Medium drops to 61 FPS, High falls to 46 FPS, and Ultra bottoms out at 44 FPS. The gap between Low and Medium is 17 FPS, but the gap between Medium and High is 15 FPS, indicating that the GPU is reaching its limits. At 4K, the situation worsens dramatically: Low averages 58 FPS, Medium 45 FPS, High 34 FPS, and Ultra 32 FPS. The difference between Low and Ultra at 4K is 26 FPS, which is smaller in absolute terms than at 1080p (43 FPS), but the overall performance is far below playable levels.

The CPU’s 89th percentile ranking among all processors suggests it is not the primary constraint. Instead, the GPU’s 68th percentile ranking aligns with the observed frame rates, particularly at higher resolutions where pixel throughput becomes the dominant factor. The Arc B580’s 12 GB of GDDR6 memory and 456.0 GB/s bandwidth are sufficient for 1080p and 1440p, but the 4K results indicate that the memory interface and compute resources are stretched thin. For users targeting 1080p or 1440p, the CPU can maintain adequate frame pacing, but at 4K, the GPU becomes the unequivocal bottleneck.

Similar Performance Alternatives

For the Intel Core Ultra 5 235, the nearest rivals in terms of average benchmark score are the AMD Ryzen AI 9 HX 375 (46,030, delta 0.1%), the Intel Core i9-13900HX (46,098, delta -0.1%), the AMD EPYC 4364P (45,970, delta 0.2%), and the AMD EPYC 7303 (45,960, delta 0.2%). The Core Ultra 5 235 scores 46,062, which is effectively identical to all of these processors, meaning any of them would deliver nearly the same CPU-bound performance in Microsoft Flight Simulator. The differences of less than 0.2% are within measurement noise, so users upgrading from or considering these alternatives should not expect any meaningful change in frame rates.

On the GPU side, the Intel Arc B580’s average score of 23,021 places it in the company of the AMD Radeon RX 580 2048SP (23,061, -0.2%), the NVIDIA GeForce RTX 2080 (22,895, 0.6%), the NVIDIA GeForce RTX 3080 (23,172, -0.7%), and the NVIDIA P106-100 (23,249, -1%). These deltas are all within 1% of the Arc B580, so any of these graphics cards would produce nearly identical FPS numbers in this game. Notably, the RTX 3080 is a much more powerful card in other contexts, but its average benchmark score here is only 0.7% higher, suggesting that the Arc B580 punches above its weight in synthetic tests. For flight simulator purposes, swapping to any of these GPUs would change results by less than a frame on average.

Measured FPS Breakdown

At 1920x1080, the system delivers its strongest performance. On Low settings, the average FPS is 97, which is well above the 60 FPS threshold and provides a smooth experience. Medium settings reduce the average to 76 FPS, with a minimum of 64 and maximum of 87, still comfortably playable. High settings drop to 57 FPS, which is just below the threshold and may introduce noticeable stutter in dense areas. Ultra settings average 54 FPS, with no recorded minimum or maximum values, indicating a generally consistent but sub-60 experience.

At 2560x1440, the numbers shift downward. Low settings average 78 FPS, which remains playable, while Medium averages 61 FPS with a minimum of 52 and maximum of 70. This makes Medium the highest playable preset at this resolution, though the 52 FPS minimum suggests occasional dips below the threshold. High settings average 46 FPS, and Ultra averages 44 FPS, both of which are below the playable threshold and would result in a less fluid experience during complex flight maneuvers.

At 3840x2160, the performance is marginal at best. Low settings average 58 FPS, which is tantalizingly close to 60 but still below it. Medium averages 45 FPS with a minimum of 38 and maximum of 52, while High averages 34 FPS and Ultra averages 32 FPS. None of these presets achieve the 60 FPS threshold, and even the Low preset’s 58 FPS average means the system would frequently dip below 60, making 4K unsuitable for playable frame rates.

The Verdict

This PC can run Microsoft Flight Simulator, but only under specific conditions. The verdict by resolution confirms that 1920x1080 and 2560x1440 are the only resolutions with playable settings, and in both cases, the best achievable preset is Medium. At 1080p, Medium delivers an average of 76 FPS, which is 16 FPS above the 60 FPS threshold, providing a comfortable margin for most scenarios. At 1440p, Medium averages 61 FPS, which is just barely above the threshold, meaning users may experience occasional dips to 52 FPS as seen in the minimum recorded value. At 4K, no preset clears 60 FPS, so users should avoid this resolution entirely.

For users who prioritize visual quality, the High preset at 1080p averages 57 FPS and is close to playable, but it falls short of the threshold. The Ultra preset at 1080p averages 54 FPS and is also below the mark. At 1440p, both High and Ultra are firmly in the 44-46 FPS range, which is playable for some but not smooth by the 60 FPS standard. The data indicates that this system is best suited for 1080p Medium or 1440p Medium, with no headroom for higher presets at any resolution.

Best Settings per Resolution

At 3840x2160, there is no preset that achieves an average of 60 FPS or higher. The Low preset comes closest with 58 FPS, but since it does not meet the threshold, there is no recommended setting for 4K.

At 2560x1440, the best playable preset is Medium, with an average FPS of 61. This preset also shows a minimum of 52 and maximum of 70, indicating reasonable stability. Users can choose Low for a higher average of 78 FPS, but Medium offers the best balance of visual fidelity and performance while staying above the 60 FPS threshold.

At 1920x1080, the best playable preset is also Medium, with an average of 76 FPS and a minimum of 64 and maximum of 87. This provides a solid margin above the threshold, making it the recommended choice for most users. Low settings average 97 FPS for those who prioritize frame rate over visuals, but Medium is the highest preset that maintains playable performance. High and Ultra at 1080p average 57 and 54 FPS respectively, which are below the threshold and not recommended for a consistent 60 FPS experience.
