The data reveals a system that handles the simulator's demanding rendering loads with consistent, playable frame rates across most settings, though the highest quality presets push it to its limits. The CPU's 14 cores and 14 threads, paired with a boost clock of 5.00 GHz, provide ample single-thread performance for the simulator's core simulation logic, while the GPU's 12 GB of VRAM and RDNA 2.0 architecture shoulder the heavy visual lifting.

CPU Role

The Intel Core Ultra 5 235 is a 14-core, 14-thread processor built on Arrow Lake architecture with a 3 nm process node from TSMC. Its base clock of 3.40 GHz and boost clock of 5.00 GHz place it in a strong position for Microsoft Flight Simulator, a title known for its heavy reliance on single-threaded performance for the core flight simulation model. The CPU's Cinebench R23 single-core score of 2085 and multi-core score of 14769 indicate solid performance, with the single-thread score being particularly relevant for the simulator's main thread. The 24 MB of shared L3 cache and 3 MB per-core L2 cache help feed the simulation's complex world-loading routines.

In the broader CPU landscape, the Ultra 5 235 sits at the 89th percentile of all CPUs, with an average benchmark score of 46062. Its nearest rivals show how tightly packed the mid-to-high-end market is: the AMD Ryzen AI 9 HX 375 scores 46030 (a mere 0.1% behind), the Intel Core i9-13900HX scores 46098 (0.1% ahead), the AMD EPYC 4364P scores 45970 (0.2% behind), and the AMD EPYC 7303 scores 45960 (0.2% behind). This clustering indicates that for Microsoft Flight Simulator, the Ultra 5 235's performance is squarely in the expected range for its class, with no extreme deviations either way.

The CPU's performance in synthetic benchmarks, such as PassMark's multi-thread score of 37816 and single-thread score of 4516, suggests it can handle the simulator's background tasks like terrain streaming and AI traffic alongside the main simulation loop. The data compression score of 390711 and encryption score of 29293 in PassMark further indicate robust general-purpose compute capabilities that support the simulator's data processing needs. However, the CPU's 65 W TDP and lack of an unlocked multiplier suggest it is tuned for efficiency rather than extreme overclocking headroom, which aligns with its role as a balanced desktop processor.

How This Combo Ranks

The combo's rank of 1304 out of 2996 tested combinations places it in the upper-middle tier of all CPU-GPU pairings tested for Microsoft Flight Simulator. This positioning suggests that while the system is not at the bleeding edge of performance, it outperforms roughly 56% of tested configurations. The percentile ranking reflects a balanced pairing where neither component dramatically bottlenecks the other, though the data hints at the GPU being the more significant constraint at higher settings.

The rank becomes more telling when considering the CPU's 89th percentile standing among all processors. The Intel Core Ultra 5 235 is a strong CPU by itself, yet the combo's mid-pack rank indicates that the AMD Radeon RX 6750 XT, which sits at the 71st percentile among all GPUs, holds the system back from the top echelons. The GPU's average benchmark score of 26011 places it near the AMD Radeon R9 M395X (25891, 0.5% behind), AMD FirePro W7100 (25856, 0.6% behind), AMD FirePro D700 (25842, 0.7% behind), and NVIDIA GeForce RTX 3080 Ti Mobile (25740, 1.1% behind). This clustering shows the RX 6750 XT is competitive with older high-end and mobile flagship parts, but it doesn't match the raw throughput of modern top-tier desktop GPUs.

For flight simulation enthusiasts, this rank implies that the system can deliver a satisfying experience at medium to high settings, but those seeking maximum visual fidelity at 4K will need to manage expectations. The data suggests that the combo's performance ceiling is defined more by the GPU than the CPU, which is a common pattern in Microsoft Flight Simulator given its intense graphical demands.

Resolution Scaling

The measured FPS data across resolutions reveals a clear progression of performance scaling that highlights the GPU as the primary limiting factor at higher resolutions. At 1080p with Low settings, the combo achieves 127 FPS, but this drops to 75 FPS at 4K Low — a 41% reduction. At High settings, the drop is from 74 FPS at 1080p to 44 FPS at 4K, a 41% decline. Medium settings show a similar pattern, falling from 99 FPS at 1080p to 59 FPS at 4K, a 40% decrease. The Ultra preset experiences the steepest relative drop, from 71 FPS at 1080p to 42 FPS at 4K, a 41% reduction.

This consistent ~40-41% performance penalty when moving from 1080p to 4K across all settings indicates that the GPU's rendering workload scales predictably with pixel count. The RX 6750 XT's 12 GB of GDDR6 memory and 432.0 GB/s bandwidth are sufficient to feed the render pipeline, but the 13.31 TFLOPS of FP32 compute becomes the bottleneck at higher resolutions. The fact that the percentage drop is nearly identical across all quality presets suggests that the GPU is saturated at every setting level, with the CPU having ample headroom to feed it frames.

Interestingly, the scaling from 1080p to 1440p is less severe. At Low settings, FPS drops from 127 to 102 (a 20% reduction), at Medium from 99 to 79 (20% reduction), at High from 74 to 60 (19% reduction), and at Ultra from 71 to 57 (20% reduction). This gentler scaling at 1440p indicates that the GPU can still maintain reasonable utilization without hitting memory or compute walls, making 1440p a sweet spot for this combo in Microsoft Flight Simulator.

Measured FPS Breakdown

At 1920x1080, the combo delivers its strongest performance. Low settings produce an average of 127 FPS, providing a highly fluid experience for fast-paced flight maneuvers or when flying over dense urban areas. Medium settings yield 99 FPS average with minimums of 84 FPS and maximums of 113 FPS, indicating smooth gameplay with minor frame-time variance. High settings drop to 74 FPS average, while Ultra settles at 71 FPS average. The narrow gap between High and Ultra at 1080p (74 vs 71 FPS) suggests that the visual quality gains from Ultra come at a minimal performance cost at this resolution.

At 2560x1440, performance remains playable but with noticeable drops. Low settings average 102 FPS, still well above the 60 FPS threshold for smooth simulation. Medium settings average 79 FPS with a range of 68 to 91 FPS, showing that the system can maintain a stable experience. High settings average 60 FPS, which is right at the boundary of what most players consider acceptable for a flight simulator. Ultra settings drop further to 57 FPS average, beginning to show the GPU's limitations at this resolution with maximum quality.

At 3840x2160, the system struggles to maintain high frame rates. Low settings average 75 FPS, which remains playable but represents a significant drop from lower resolutions. Medium settings average 59 FPS with a range of 50 to 67 FPS, meaning some scenes will dip below the 60 FPS threshold. High settings average 44 FPS, and Ultra drops to 42 FPS average. These 4K results indicate that while the RX 6750 XT can technically run the simulator at 4K, the experience is best suited for slower-paced flight rather than dynamic scenarios with dense scenery.

The complete dataset shows a pattern where the GPU's performance ceiling is reached at 4K Ultra, with the system unable to push beyond 42 FPS average. The 12 GB VRAM capacity is sufficient for the simulator's textures, but the raw compute power of the GPU becomes the limiting factor. The Medium settings at 1440p (79 FPS average) and High settings at 1080p (74 FPS average) represent the best balance of visual quality and performance in the measured data.

At 1080p, the Ultra preset at 71 FPS average is the best choice, as it delivers a fully smooth experience with only a 3 FPS penalty compared to High settings. The minimal performance gap between High (74 FPS) and Ultra (71 FPS) suggests that players should prioritize visual fidelity at this resolution without worrying about frame rate degradation.

At 1440p, the recommendation becomes more nuanced. Medium settings at 79 FPS average provide a comfortable margin above the 60 FPS threshold, while High settings at exactly 60 FPS average sit right at the boundary. For players who prioritize smoothness, Medium is the safer choice. Those who can tolerate occasional dips below 60 FPS may prefer High settings, but the data shows Ultra at 57 FPS average is borderline for consistent playability.

At 4K, the choices are more constrained. Low settings at 75 FPS average offer the only fully smooth experience, while Medium at 59 FPS average is borderline. High and Ultra at 44 and 42 FPS respectively are not recommended for dynamic flight scenarios, as the frame rates will feel choppy. The data suggests that 4K play is best reserved for scenic flying at low altitudes where frame rate fluctuations are less noticeable.

Overall, the combination of 1440p Medium or 1080p Ultra provides the best balance of visual quality and performance. The narrow performance gap between High and Ultra at 1080p makes Ultra the clear winner at that resolution, while the larger gap at 1440p favors Medium for consistent frame times.

GPU Role

The AMD Radeon RX 6750 XT is built on the RDNA 2.0 architecture with the Navi 22 chip, fabricated on a 7 nm process from TSMC. Its 2560 shading units, 160 texture mapping units, and 64 raster output pipelines provide the rendering horsepower for Microsoft Flight Simulator's complex scenery. The GPU's boost clock of 2600 MHz and game clock of 2495 MHz keep it competitive in the mid-range segment, while the 12 GB of GDDR6 memory on a 192-bit bus delivers 432.0 GB/s of bandwidth.

The GPU's 40 ray tracing cores are present but not heavily utilized in Microsoft Flight Simulator, as the game's primary rendering load comes from traditional rasterization. The 13.31 TFLOPS of FP32 compute is the key specification for this title, as it determines how quickly the GPU can process the simulator's detailed terrain and aircraft models. The 166.4 GPixel/s pixel rate and 416.0 GTexel/s texture rate indicate how the GPU handles the high-resolution textures and geometry that the simulator streams.

In the context of the measured performance, the RX 6750 XT's 71st percentile ranking among all GPUs aligns with the observed frame rates. The GPU's average benchmark score of 26011 places it in the company of older high-end parts like the AMD Radeon R9 M395X (25891, 0.5% behind) and AMD FirePro W7100 (25856, 0.6% behind), as well as the NVIDIA GeForce RTX 3080 Ti Mobile (25740, 1.1% behind). This positioning suggests the RX 6750 XT is a capable but not exceptional GPU for modern demanding titles.

The GPU's 12 GB VRAM capacity proves sufficient for Microsoft Flight Simulator at all tested settings, as no memory-related stuttering was evident in the frame rate data. The 432.0 GB/s memory bandwidth supports the high-resolution texture streaming that the simulator relies on, though the 192-bit bus width limits peak bandwidth compared to higher-end cards. The GPU's 250 W TDP and dual-slot design indicate it requires adequate cooling and power delivery, but these are standard requirements for its performance class.

The measured FPS data shows the GPU's performance ceiling is reached at 4K Ultra, where the 42 FPS average represents the system's absolute limit. At 1080p, the GPU has enough headroom to deliver 127 FPS at Low settings, indicating that the CPU can feed it frames faster than it can render them at lower resolutions. This pattern confirms the GPU as the primary performance constraint in this combo, particularly at higher resolutions and quality settings.
