Microsoft Flight Simulator

The Intel Core Ultra 9 275HX paired with the AMD Radeon 880M delivers a severely limited experience in Microsoft Flight Simulator, ranking in the bottom 2.4% of all tested combinations. The data shows a hard ceiling imposed by the integrated graphics, where even the most CPU-favoring settings fail to produce playable frame rates. This is a configuration for low-resolution, low-detail testing only, not for practical flight simulation.

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

The Intel Core Ultra 9 275HX is a 24-core, 24-thread mobile processor based on the Arrow Lake-HX architecture. It operates at a base clock of 2.70 GHz and reaches a boost clock of 5.40 GHz, with a 55 W TDP. This is a high-end part in raw compute terms, placing in the 94th percentile of all CPUs tested on this database. Its synthetic performance is substantial: a Cinebench R23 multi-core score of 35589 and a single-core score of 2204, along with a Geekbench multi-core score of 20795. These numbers indicate that the processor itself is not the primary bottleneck in most scenarios.

However, in Microsoft Flight Simulator, the measured frame rates tell a different story. At 1080p Low, the combo achieves 47 FPS, which is the highest result in the entire measured set. At 1080p Ultra, that drops to 26 FPS. The CPU has ample headroom; the game’s engine is not being starved for processing power. The 24 cores and high boost clock are largely irrelevant when the graphics subsystem cannot keep pace. The data shows that even with the CPU's strong single-thread performance (a Cinebench R20 single-core score of 2809), the frame rates remain low across all settings, confirming that the processor is idle much of the time while waiting on the GPU.

The Intel Core Ultra 9 275HX’s nearest rivals in the CPU benchmark database include the Intel Xeon w5-3525 (0.3% slower), the AMD EPYC 4484PX (0.5% slower), and the AMD Ryzen Threadripper PRO 5955WX (0.6% slower). The Ultra 9 275HX is effectively tied with these workstation-class parts in average score, proving its compute capability. Yet in this game, that capability yields nothing beyond a baseline of performance. The processor’s 36 MB of shared L3 cache and support for DDR5 memory with a dual-channel bus (102.4 GB/s bandwidth) are adequate for flight simulation’s world-streaming demands, but the data indicates that the CPU never becomes the limiting factor. The bottleneck lies elsewhere, and the frame rates scale almost entirely with the GPU’s workload.

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

The AMD Radeon 880M is an integrated graphics processor (IGP) based on the RDNA 3.5 architecture, built on a 4 nm process. It has a base clock of 400 MHz and a boost clock of 2900 MHz, with a 15 W TDP. Critically, its memory is "System Shared," meaning it uses the system’s DDR5 RAM rather than dedicated VRAM. The memory bandwidth is listed as "System Dependent," which in this configuration is the Achilles' heel. The GPU has 768 shading units, 48 texture mapping units, and 16 raster operation units, with 12 ray tracing cores. Its theoretical peak performance is 4.454 TFLOPS of FP32 compute.

The benchmark results are stark. The GPU sits in the 43rd percentile of all GPUs, with an average score of 8436. Its nearest rivals are the NVIDIA GeForce GTX 675MX (0.1% faster), the NVIDIA GeForce MX330 (0.3% faster), and the AMD Radeon HD 8870M (0.3% faster). These are all legacy discrete mobile parts from a decade ago. The 880M’s Passmark G3D score of 7615 and DirectX 12 score of 32 reflect a part that is fundamentally unsuited for heavy 3D rendering.

In Microsoft Flight Simulator, the GPU’s limitations are exposed immediately. At 1080p Low, the combo produces 47 FPS, but this is the only setting that approaches playability. At 1080p Medium, it falls to 37 FPS, and at 1080p High, it drops to 28 FPS. The 4K results are catastrophic: 16 FPS at High, 22 FPS at Medium, and 28 FPS at Low. The data shows a clear pattern: the frame rate is directly tied to the pixel count and the detail level, which are both processed by the GPU. The lack of dedicated VRAM means the IGP must share memory bandwidth with the CPU, causing severe contention as resolution and texture quality increase. This is why the difference between 1080p Low and 4K Low is a 19 FPS drop—the GPU is overwhelmed by the fill rate and memory traffic demands.

How This Combo Ranks — use comboRankInGame vs other tested combos

The combination of the Intel Core Ultra 9 275HX and AMD Radeon 880M ranks 2924 out of 2996 tested combos in Microsoft Flight Simulator. This places it in the bottom 2.4% of all configurations, a position that reflects the GPU’s severe handicap rather than any CPU deficiency. The data indicates that this combo is outclassed by nearly every other pairing, including those with older, slower processors but dedicated graphics cards.

The rank is not a reflection of the CPU’s standing—the Ultra 9 275HX is a 94th-percentile processor. Instead, it is a measure of the integrated GPU’s inability to drive this simulation. The 880M’s 43rd-percentile GPU ranking and its nearest rivals being GTX 675MX and MX330-class parts confirm that this is entry-level or legacy-tier graphics performance. In a game like Microsoft Flight Simulator, which is known for its heavy GPU load at higher settings, this combo is effectively non-competitive. The 2924th rank means that 72 other combos are even slower, but that is faint consolation; the absolute frame rates are still below the threshold for a smooth experience in almost every configuration tested.

The data shows a large gap between this combo and anything with a discrete GPU. While the CPU can feed the game engine, the GPU cannot render the frames. The result is a system that is theoretically capable of high-end compute but practically limited to low-resolution, low-detail flight simulation. The rank serves as a warning: do not pair a high-end mobile CPU with an IGP for this game.

FAQ

Q: What is the best frame rate this combo can achieve in Microsoft Flight Simulator?

A: The highest measured average FPS is 47, achieved at 1920x1080 with Low settings. This is the only setting that exceeds 40 FPS.

Q: Is the Intel Core Ultra 9 275HX the bottleneck in this configuration?

A: No. The CPU ranks in the 94th percentile of all processors, with a Cinebench R23 multi-core score of 35589. The frame rates are nearly identical when comparing 1080p Low and 4K Low (47 vs 28 FPS), indicating the GPU is the limiting component.

Q: How does the AMD Radeon 880M compare to its closest rivals?

A: The 880M’s average benchmark score of 8436 is within 0.3% of the NVIDIA GeForce GTX 675MX and 0.3% of the NVIDIA GeForce MX330. It is also 1.3% faster than the AMD Radeon R9 M375X.

Q: What resolution and settings produce the most playable experience?

A: The only playable result is 1080p Low, which yields 47 FPS. All other settings at 1080p and above fall below 40 FPS, with 4K Ultra producing just 16 FPS.

Q: Does the game benefit from the CPU’s high core count?

A: The data suggests no. The CPU has 24 cores and a boost clock of 5.40 GHz, but the frame rate does not improve with CPU headroom. The GPU’s shared memory and low fill rate cap performance far below what the CPU can support.

Q: What is the GPU’s memory configuration, and how does it affect performance?

A: The GPU uses System Shared memory with a bandwidth listed as System Dependent. This means it shares the system’s DDR5 memory, which is a primary cause of the severe FPS drops at higher resolutions.

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

The measured FPS data shows a consistent and predictable decline as resolution increases, which is a textbook sign of a GPU-bound scenario. At Low settings, the frame rates are 47 FPS at 1080p, 38 FPS at 1440p, and 28 FPS at 4K. This represents a 40% drop from 1080p to 4K. At Medium settings, the drop is from 37 FPS at 1080p to 29 FPS at 1440p and 22 FPS at 4K—a 41% reduction. At High settings, the numbers are 28 FPS, 22 FPS, and 16 FPS, respectively, a 43% drop. At Ultra, the trend continues: 26 FPS, 21 FPS, and 16 FPS, a 38% drop.

These percentages are remarkably consistent across all settings, indicating that the GPU’s pixel throughput is the primary constraint. If the CPU were the bottleneck, we would expect to see a smaller FPS difference between 1080p and 4K, because the CPU workload would remain similar. Instead, the frame rate scales almost linearly with the number of pixels rendered. The 880M’s shared memory architecture exacerbates this, as the memory bandwidth is "System Dependent" and cannot keep up with the increased data transfer demands of higher resolutions.

The data also reveals that the gap between settings narrows at 4K. At 1080p, the difference between Low and Ultra is 21 FPS (47 vs 26). At 4K, the difference is only 12 FPS (28 vs 16). This compression suggests that at 4K, the GPU is so overwhelmed that even lowering the settings cannot fully compensate for the pixel count. The limiting component is unequivocally the GPU, as the CPU’s strong single-core and multi-core scores (2204 and 35589 in Cinebench R23) are not reflected in any meaningful FPS advantage.

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

Based on the measured rows, the only viable configuration for Microsoft Flight Simulator is 1920x1080 with Low settings, which produces an average of 47 FPS. This is the sole preset that exceeds the 40 FPS threshold that most users consider minimally playable for a simulator. All other settings at 1080p fall below this: Medium averages 37 FPS, High averages 28 FPS, and Ultra averages 26 FPS. The data shows that the jump from Low to Medium costs 10 FPS, which is a significant 21% reduction, while the jump from High to Ultra costs only 2 FPS.

At 2560x1440, no preset achieves playable frame rates. Low is the best at 38 FPS, followed by Medium at 29 FPS, High at 22 FPS, and Ultra at 21 FPS. The 1440p Low result is 9 FPS slower than 1080p Low, indicating that the resolution increase is not worth the performance penalty. At 3840x2160, the situation is dire: Low averages 28 FPS, Medium averages 22 FPS, and both High and Ultra average 16 FPS. These are all far below playable levels.

The recommendation is clear: use 1080p Low. This preset offers the highest FPS and the only smooth experience. If the user insists on higher visual quality, Medium at 1080p is the next best option at 37 FPS, but the data shows that the 880M cannot sustain a consistent frame rate, with a minimum of 31 FPS recorded. For any resolution above 1080p, the measured FPS drops below 40, making the game feel sluggish and unresponsive. The data suggests that the user should prioritize frame rate over detail, as the GPU’s shared memory and low compute power (4.454 TFLOPS) are insufficient for higher presets.
