Microsoft Flight Simulator

Microsoft Flight Simulator is a uniquely demanding title, and the combination of the Intel Core Ultra 5 235 and AMD Radeon RX 6650 XT produces a system that is consistently bound by the graphics card, especially at higher resolutions. The benchmark data shows a processor with substantial headroom, as the frame rate scales almost entirely with GPU workload. This pairing is capable of delivering playable performance at 1080p and 1440p, but it struggles to maintain smooth frame rates at 4K, where the GPU's 8 GB memory and mid-range compute power become the definitive bottleneck.

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

The Intel Core Ultra 5 235 is a 14-core, 14-thread processor based on the Arrow Lake architecture, with a base clock of 3.40 GHz and a boost clock of 5.00 GHz. The data indicates this CPU is not the limiting factor in this game. Its PassMark single-thread score of 4516 and multi-thread score of 37816 place it in the 89th percentile of all CPUs, which is a strong indicator of its ability to handle the simulation's heavy single-threaded physics and rendering calls. While the game is known for pushing CPU limits, the measured FPS shows that the GPU is the primary constraint in this specific configuration.

The processor's 24 MB of shared L3 cache and dual-channel DDR5 memory support provide a robust foundation for feeding the GPU. In this context, the CPU's performance is best understood by comparing it to its nearest rivals. The data shows the Core Ultra 5 235 is essentially tied with the AMD Ryzen AI 9 HX 375, with a deltaPct of 0.1%, and is just 0.1% behind the Intel Core i9-13900HX. This means that in a CPU-bound scenario, the 235 would perform nearly identically to these high-end mobile and desktop parts. However, the measured FPS in Microsoft Flight Simulator does not show a CPU bottleneck; instead, the frame rates drop by roughly 30% when moving from 1080p to 4K at the same settings, which is a classic sign of GPU limitation.

The fact that the CPU's benchmark scores are high, yet the system's performance in the game scales so heavily with resolution, suggests that the processor is waiting on the GPU. For example, at 1080p High settings, the system achieves 61 FPS, but at 4K High settings, it falls to 36 FPS. This 25 FPS drop is far more than what a CPU limitation would cause, as the CPU's workload does not increase proportionally with pixel count. The Core Ultra 5 235 is a capable air-cooled desktop part with a 65 W TDP, and its performance headroom is evident; it is not the component that holds back the experience in this title.

FAQ — 4-6 Q&A pairs answerable from FACT PACK data

Q: What is the best resolution for this CPU and GPU combo in Microsoft Flight Simulator?

A: The data shows that 1080p is the most comfortable resolution, with all settings presets achieving above 58 FPS. At 1440p, performance is still acceptable, ranging from 47 FPS on Ultra to 84 FPS on Low, but 4K is the most challenging, with only the Low preset achieving a playable 62 FPS.

Q: How does the CPU's performance compare to its closest rivals?

A: The Intel Core Ultra 5 235 has an average benchmark score of 46062, placing it 0.1% ahead of the AMD Ryzen AI 9 HX 375 and 0.1% behind the Intel Core i9-13900HX. It is also 0.2% ahead of both the AMD EPYC 4364P and AMD EPYC 7303.

Q: What is the limiting component at 4K resolution?

A: The AMD Radeon RX 6650 XT is the limiting component at 4K. The frame rates drop significantly from 1080p to 4K at the same settings, and the GPU's 8 GB VRAM and 128-bit memory bus are insufficient for the high-resolution textures and rendering demands of the game.

Q: What is the highest average FPS achievable with this pair?

A: The highest average FPS is 105, achieved at 1080p with the Low settings preset. This indicates that the system has significant headroom when graphical demands are reduced.

Q: How does the GPU's performance percentile reflect its capability?

A: The AMD Radeon RX 6650 XT sits in the 65th percentile of all GPUs, with an average benchmark score of 19765. This places it in the mid-range tier, and its nearest rivals are older professional cards like the NVIDIA Tesla K40m and AMD FirePro W7000, which are not modern gaming parts.

Q: Is the CPU's 14-thread configuration sufficient for this game?

A: Yes, the data suggests it is more than sufficient. The CPU's PassMark multi-thread score of 37816 is high, and the frame rate scaling with resolution indicates that the GPU is the bottleneck, not the CPU's thread count.

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

The measured FPS data reveals a clear pattern of GPU-bound performance. At the High settings preset, the average frame rate drops from 61 FPS at 1080p to 49 FPS at 1440p, and then to 36 FPS at 4K. This represents a 20% decrease from 1080p to 1440p and a further 27% decrease from 1440p to 4K. This scaling is characteristic of a graphics card that is overwhelmed by the pixel count, as the CPU's workload remains relatively constant across these resolutions.

The story is similar for the Medium preset. At 1080p, the system achieves 81 FPS; at 1440p, it drops to 66 FPS; and at 4K, it falls to 48 FPS. The gap between 1080p and 4K is 33 FPS, or a 41% reduction. This is a substantial drop that cannot be explained by CPU limitations. The Core Ultra 5 235 has enough single-thread performance to feed the GPU at lower resolutions, but as the resolution increases, the GPU must render more pixels, and its compute resources become the limiting factor.

The Low preset shows the same trend, with 105 FPS at 1080p, 84 FPS at 1440p, and 62 FPS at 4K. The fact that even on Low settings the frame rate drops by 43 FPS from 1080p to 4K confirms that the GPU is the primary constraint. The CPU is not the bottleneck here, as its performance is sufficient to push the frame rate higher at lower resolutions. This analysis strongly suggests that if a more powerful GPU were paired with the Core Ultra 5 235, the frame rates at all resolutions would increase, particularly at 4K.

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

The benchmark results provide a complete picture of performance across three resolutions and four settings presets. At 1920x1080, the system is at its most capable. The Low preset delivers an average of 105 FPS, which is very smooth. The Medium preset yields 81 FPS, with a minimum of 69 FPS and a maximum of 94 FPS. The High preset achieves 61 FPS, and the Ultra preset drops to 58 FPS. These numbers indicate that 1080p is the sweet spot for this hardware, as even the Ultra preset stays above the 60 FPS threshold.

Moving to 2560x1440, the performance becomes more demanding. The Low preset still delivers a solid 84 FPS. The Medium preset averages 66 FPS, with a minimum of 56 FPS and a maximum of 75 FPS, which is playable but with occasional dips. The High preset drops to 49 FPS, which is below the ideal 60 FPS mark. The Ultra preset falls to 47 FPS, indicating that high-fidelity gaming at this resolution will require compromises.

At 3840x2160, the GPU is clearly struggling. The Low preset is the only one that reaches a playable average, at 62 FPS. The Medium preset averages 48 FPS, with a minimum of 41 FPS and a maximum of 56 FPS, which will be noticeable as stutter. The High preset averages 36 FPS, and the Ultra preset averages 35 FPS. These results show that 4K gaming is only viable on the lowest settings, and even then, the frame rate is not ideal for a smooth experience.

The overall combo rank in the game's benchmark database is 1902 out of 2996 combinations, which places this system in the lower half of tested configurations. This ranking is a reflection of the GPU's limitations at high resolutions, rather than the CPU's capabilities.

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

The AMD Radeon RX 6650 XT is the defining component in this system's gaming performance. It features 8 GB of GDDR6 memory on a 128-bit bus, with a bandwidth of 280.3 GB/s. The GPU has a base clock of 2055 MHz and a boost clock of 2635 MHz, with a game clock of 2410 MHz. The 8 GB VRAM is a critical factor in Microsoft Flight Simulator, as the game is known for its massive textures and detailed scenery. At 4K resolution, the VRAM capacity is likely exceeded, leading to texture swapping and performance degradation.

The GPU's compute performance, at 10.79 TFLOPS FP32, is modest by modern standards, and it sits in the 65th percentile of all GPUs. Its nearest rivals in the benchmark database are the NVIDIA Tesla K40m and the AMD FirePro D300, which are professional workstation cards from a different era. This comparison highlights that the RX 6650 XT is a mid-range gaming part that is not designed for 4K gaming at high settings. The GPU's DirectX 12 score of 62 in PassMark is a low number, further indicating its limitations in modern APIs.

The data shows that the GPU is the primary bottleneck at all resolutions. Even at 1080p, the difference between the Low preset (105 FPS) and Ultra preset (58 FPS) is 47 FPS, which shows how much the GPU's workload affects the frame rate. The CPU, on the other hand, has enough headroom to allow these frame rate variations. If the GPU were stronger, the frame rates would be more consistent across settings, as the CPU would be able to keep up.

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

Based on the measured FPS data, the optimal settings preset depends heavily on the target resolution and the user's preference for smoothness over visual fidelity. At 1080p, the High preset is the best balance, offering 61 FPS, which is just above the 60 FPS threshold for smooth gameplay. The Ultra preset at 58 FPS is also acceptable, but the 3 FPS gain from High to Ultra is not worth the performance cost. For a more stable experience, the Medium preset at 81 FPS is the best choice for ensuring high frame rates with good visuals.

At 1440p, the situation is more complex. The Medium preset, at 66 FPS, is the only one that provides a frame rate above 60 FPS, with a minimum of 56 FPS. This is the recommended preset for a balance of visual quality and smoothness. The High preset at 49 FPS and Ultra at 47 FPS are not ideal, as they will cause noticeable stutter. For users who prioritize frame rate over visuals, the Low preset at 84 FPS is the best option.

At 4K, the data suggests that the system is not well-suited for high-fidelity gaming. The Low preset at 62 FPS is the only playable option, but it compromises visual quality significantly. The Medium preset at 48 FPS is borderline, with a minimum of 41 FPS that will be noticeable. The High and Ultra presets, at 36 FPS and 35 FPS, respectively, are not recommended, as they provide a poor experience. For a 4K experience, users should stick to the Low preset or consider lowering the resolution to 1440p and using the Medium preset for a better overall experience. The data clearly indicates that the GPU is the limiting factor, and settings should be adjusted to reduce the GPU's workload.
