# Microsoft Flight Simulator: Intel Core Ultra 9 275HX + NVIDIA GeForce RTX 4080

This combination of Intel's Core Ultra 9 275HX mobile processor and NVIDIA's GeForce RTX 4080 laptop GPU produces a 917th-place ranking out of 2,996 tested combos in Microsoft Flight Simulator, placing it in the 69th percentile of all configurations. The pairing demonstrates solid performance headroom across resolution tiers, though the data reveals interesting bottlenecks that shift depending on settings and pixel count.

How This Combo Ranks

The combo rank of 917 out of 2,996 tested configurations places this system firmly in the upper third of all tested hardware pairings for Microsoft Flight Simulator. With 2,079 other combos ranking below it, this setup outperforms roughly 69% of the tested field, a respectable showing for a mobile platform. The rank reflects a balanced pairing where neither component completely overshadows the other, though the measured FPS data suggests the GPU becomes the primary constraint at higher resolutions while the CPU handles lower-resolution workloads with ample headroom.

Comparing the individual components to their nearest rivals provides context for this ranking. The Core Ultra 9 275HX posts an average benchmark score of 67,469, sitting within 0.7% of the Intel Xeon 6515P (67,006) and just 0.3% below the Intel Xeon w5-3525 (67,673). This tight clustering places the mobile chip in workstation-class territory for synthetic workloads, though Microsoft Flight Simulator's demands differ significantly from those benchmarks. The RTX 4080 laptop GPU, with its average score of 54,247, lands within 0.1% of the RTX 4080 SUPER (54,209) and trails the AMD Radeon RX 6750 GRE 12 GB (55,698) by 2.6%. This puts the GPU in close competition with desktop parts despite its mobile form factor.

The 86th percentile ranking for the GPU versus all GPUs and 94th percentile for the CPU versus all CPUs suggests the processor is relatively stronger in the synthetic benchmark landscape. However, the in-game rank of 917 out of 2,996 indicates that real-world flight simulation performance depends heavily on how these components interact, particularly given the game's known CPU sensitivity in certain scenarios.

CPU Role

The Intel Core Ultra 9 275HX brings 24 cores and 24 threads to the table, a configuration that omits hyperthreading entirely. This design choice, combined with Arrow Lake architecture built on a 3 nm process at TSMC, delivers strong single-threaded performance that flight simulators heavily favor. The base clock of 2.70 GHz can boost up to 5.40 GHz, giving the processor significant frequency headroom for bursty simulation workloads that involve physics calculations, AI traffic, and weather system updates.

Synthetic benchmarks paint a picture of a capable processor: Cinebench R23 multi-core scores 35,589, while single-core reaches 2,204. Geekbench results show 20,795 multi-core and 2,458 single-core, with PassMark single-thread performance at 4,713. These numbers place the CPU in the 94th percentile of all processors, indicating it outperforms the vast majority of available chips in general computing tasks. The L3 cache totals 36 MB shared across cores, with 3 MB L2 per core and 192 KB L1 per core, providing substantial on-die storage for simulation data.

For Microsoft Flight Simulator specifically, the CPU's role becomes evident when examining FPS at lower resolutions where the GPU isn't the limiting factor. At 1080p Low, the combo achieves 151 FPS, suggesting the CPU can feed frames quickly when graphical load is minimal. The 24 threads handle the game's multi-threaded rendering pipeline well, though the lack of hyperthreading means the processor relies on physical cores rather than logical threads for concurrency. Given that the CPU's nearest rival scores differ by less than 1%, the 275HX's performance profile is well-established relative to workstation-grade alternatives.

GPU Role

The NVIDIA GeForce RTX 4080 in this configuration carries 16 GB of GDDR6X memory across a 256-bit bus, delivering 716.8 GB/s of bandwidth. The GPU's boost clock reaches 2,505 MHz with a base of 2,205 MHz, and its 9,728 shading units process geometry and pixel data through 304 texture mapping units and 112 raster output pipelines. Built on Ada Lovelace architecture at 5 nm, this mobile part includes 76 RT cores and 304 tensor cores, enabling hardware-accelerated ray tracing and DLSS features that flight simulation enthusiasts might leverage.

The GPU's average benchmark score of 54,247 places it in the 86th percentile of all GPUs, with its nearest rival being the RTX 4080 SUPER at nearly identical performance (0.1% delta). This suggests the mobile 4080 trades blows with its desktop SUPER counterpart in synthetic workloads, an impressive feat given power constraints. The 320 W TDP and triple-slot design indicate this is a high-power mobile implementation, requiring a 700 W suggested PSU in desktop terms.

Looking at measured FPS data, the GPU's influence becomes clear at higher resolutions. At 4K Ultra, the combo manages 50 FPS, while dropping to 4K Low yields 90 FPS — a 40 FPS swing purely from settings changes. This demonstrates that the GPU has significant headroom when graphical load is reduced, but at Ultra settings, the 4K resolution pushes the RTX 4080 to its limits. The 16 GB VRAM capacity proves sufficient for the game's texture-heavy environments, as no memory-related stuttering appears in the min FPS data at Medium settings (59 FPS minimum at 4K).

Resolution Scaling

The measured FPS data reveals clear resolution scaling trends across all settings presets. Starting at 1080p Low with 151 FPS, dropping to 1440p Low yields 122 FPS (a 29 FPS reduction), and 4K Low produces 90 FPS (another 32 FPS drop). This consistent decline indicates that even at Low settings, higher pixel counts increasingly tax the GPU.

At Medium settings, the pattern continues: 1080p delivers 118 FPS, 1440p drops to 95 FPS, and 4K reaches 70 FPS. The minimum FPS values at Medium settings show similar scaling — 100 FPS at 1080p, 81 FPS at 1440p, and 59 FPS at 4K — suggesting stable frame delivery without major stutters. The maximum FPS at Medium settings scales from 135 at 1080p to 109 at 1440p and 80 at 4K.

High settings exhibit the same trend: 88 FPS at 1080p, 71 FPS at 1440p, and 53 FPS at 4K. Ultra settings follow with 84 FPS, 68 FPS, and 50 FPS respectively. The percentage drop from 1080p to 4K at each setting level reveals where the bottleneck shifts. At Low settings, the 1080p-to-4K reduction is 40.4% (151 to 90 FPS), while at Ultra it's 40.5% (84 to 50 FPS). This consistency suggests the GPU handles resolution scaling proportionally regardless of settings, meaning the RTX 4080 remains the primary constraint as pixel count increases.

The CPU's role becomes evident when comparing settings at the same resolution. At 1080p, moving from Low to Ultra only costs 67 FPS (151 to 84), indicating the CPU can maintain high frame rates even with reduced graphical load. However, at 4K, the same settings change costs just 40 FPS (90 to 50), showing the GPU's diminishing returns at higher resolutions.

Settings Recommendations

For players prioritizing smooth frame rates, Low settings at 1080p deliver 151 FPS average, making this the best choice for competitive or fast-paced scenarios where frame rate matters most. Medium settings at 1440p provide a balanced experience with 95 FPS average and minimums of 81 FPS, ensuring consistent performance without sacrificing too much visual fidelity.

At 4K, Medium settings offer the best compromise between visual quality and playability, with 70 FPS average and 59 FPS minimums. While Ultra at 4K achieves 50 FPS, the Medium preset's 20 FPS advantage over Ultra at the same resolution makes it the recommended choice for 4K displays. The High preset at 4K (53 FPS) sits between Medium and Ultra, but the marginal improvement over Medium doesn't justify the 17 FPS drop from Medium to High.

For those with high-refresh-rate 1440p monitors, High settings at 71 FPS average might be preferable if visual detail takes priority over maximum frame rates. However, the data suggests that Medium at 1440p (95 FPS) provides a 24 FPS advantage over High with presumably similar visual improvements. The Ultra preset at any resolution below 4K delivers playable frame rates (68 FPS at 1440p, 84 FPS at 1080p) but doesn't offer enough of an improvement over High to warrant the performance cost.

Measured FPS Breakdown

At 1920x1080, the combo delivers 151 FPS at Low, 118 FPS at Medium (with 100 FPS minimum and 135 FPS maximum), 88 FPS at High, and 84 FPS at Ultra. These numbers show a 67 FPS spread between the lowest and highest settings, with the Medium preset's minimum FPS of 100 indicating smooth frame delivery even during complex flight scenarios.

Moving to 2560x1440, performance scales down predictably: Low achieves 122 FPS, Medium reaches 95 FPS (81 minimum, 109 maximum), High produces 71 FPS, and Ultra delivers 68 FPS. The gap between Medium and High at 1440p is 24 FPS, while the difference between High and Ultra narrows to just 3 FPS, suggesting the Ultra preset offers minimal visual gains over High at this resolution.

At 3840x2160, the GPU becomes the clear limiting factor: Low yields 90 FPS, Medium drops to 70 FPS (59 minimum, 80 maximum), High manages 53 FPS, and Ultra bottoms out at 50 FPS. The Medium preset's minimum of 59 FPS at 4K indicates that even during demanding scenes, the combo maintains playable frame rates. The 40 FPS difference between Low and Ultra at 4K demonstrates the significant GPU workload increase from higher graphical settings.

The overall data pattern shows diminishing returns from High to Ultra at every resolution, while the jump from Low to Medium provides substantial FPS gains alongside improved visuals. For this CPU-GPU pairing, Medium settings at 1440p or 4K represent the sweet spot, with 95 FPS and 70 FPS averages respectively, offering the best balance of performance and image quality across all measured configurations.
