This combination of the Intel Core Ultra 9 275HX and NVIDIA GeForce RTX 5080 Mobile delivers a measured performance profile in Microsoft Flight Simulator that places it at rank 984 out of 3714 tested combos, putting it in the upper third of all tested configurations. The data shows a system capable of smooth flight simulation across most settings, though the demanding nature of this title becomes apparent at higher resolutions and quality presets.

How This Combo Ranks

The combo rank of 984 out of 3714 tested combinations means this system sits comfortably in the top 26.5% of all tested hardware pairings for Microsoft Flight Simulator. This position reflects a balanced configuration where both the 24-core processor and the Blackwell-architecture GPU contribute meaningfully to the experience. The CPU itself ranks in the 94th percentile against all CPUs in the database, with an average benchmark score of 67469. That places it just 0.3% behind the Intel Xeon w5-3525 and 0.5% behind the AMD EPYC 4484PX, while being 0.7% ahead of the Intel Xeon 6515P. These are extremely tight margins — the Core Ultra 9 275HX is effectively trading blows with workstation-class server processors in raw compute performance.

The GPU, meanwhile, sits in the 81st percentile against all GPUs, with an average benchmark score of 38349. Its nearest rival is the NVIDIA GeForce MX570, which trails by just 0.1%, while the RTX 4080 Mobile is 0.6% behind. This near-parity with the previous generation's flagship mobile GPU is noteworthy — the RTX 5080 Mobile's average score of 38349 is only 214 points higher than the RTX 4080 Mobile's 38135. The overall combo ranking in this specific game suggests that the CPU's strong multi-threaded performance is being leveraged effectively, since Microsoft Flight Simulator is known to scale with processor capability. The rank of 984 indicates that roughly three-quarters of tested combos deliver either higher frame rates or better consistency in this title, which aligns with the measured FPS numbers showing playable but not exceptional results at the most demanding settings.

GPU Role

The NVIDIA GeForce RTX 5080 Mobile brings 16 GB of GDDR7 memory on a 256-bit bus, yielding a bandwidth of 896.0 GB/s. This memory configuration is substantial for a flight simulator that streams terrain and scenery data continuously. The GPU's base clock runs at 975 MHz with a boost clock of 1500 MHz, while the memory operates at 1750 MHz with 28 Gbps effective transfer. The Blackwell 2.0 architecture implements 7680 shading units, 240 texture mapping units, and 96 ROPs, with 60 RT cores and 240 tensor cores available for accelerated workloads.

The measured frame rates in Microsoft Flight Simulator show that this GPU handles the 16 GB VRAM allocation comfortably across all tested settings and resolutions. At 4K Ultra, the average FPS drops to 54, while at 4K Low it reaches 96. The gap between these two extremes — 42 FPS — indicates that the GPU's shading and texture throughput is heavily taxed by the Ultra preset's additional visual effects. The FP32 throughput of 23.04 TFLOPS provides the raw compute foundation, and the pixel rate of 144.0 GPixel/s combined with a texture rate of 360.0 GTexel/s explains why the card can maintain over 90 FPS at 1080p even on High settings. The GPU's 81st percentile ranking against all GPUs, with an average benchmark score of 38349, places it in a competitive position, though the near-tie with the RTX 4080 Mobile suggests that generational gains in this specific workload are modest.

CPU Role

The Intel Core Ultra 9 275HX is a 24-core, 24-thread processor based on the Arrow Lake-HX architecture, built on a 3 nm process at TSMC with 17,800 million transistors on a 243 mm² die. It operates at a base clock of 2.70 GHz with a boost clock of 5.40 GHz, drawing a TDP of 55 W. The cache hierarchy includes 192 KB of L1 per core, 3 MB of L2 per core, and 36 MB of shared L3 cache. Memory support is DDR5 over a dual-channel bus, providing 102.4 GB/s of bandwidth.

For Microsoft Flight Simulator, the CPU's multi-threaded capability is critical because the simulation engine handles physics, weather, and AI traffic across multiple threads. The Cinebench R23 multi-core score of 35589 and single-core score of 2204 demonstrate strong performance in both heavily threaded and lightly threaded scenarios. The Geekbench multi-core score of 20795 and single-core score of 2458 reinforce this profile. The PassMark multi-thread score of 55759 and single-thread score of 4713 show that the processor can feed the GPU with sufficient draw calls and simulation updates. The 94th percentile ranking against all CPUs, with an average benchmark score of 67469, places this chip in elite company — its nearest rivals include the Intel Xeon w5-3525 at 67673 (0.3% ahead) and the AMD EPYC 4484PX at 67822 (0.5% ahead). The high boost clock of 5.40 GHz is particularly relevant for flight simulation, where single-threaded performance often dictates minimum frame rates during complex scenery loading.

Measured FPS Breakdown

At 1920x1080, the combination produces an average of 162 FPS on Low settings, 126 FPS on Medium, 95 FPS on High, and 90 FPS on Ultra. The Medium preset shows a minimum of 107 FPS and a maximum of 145 FPS, indicating good frame pacing with a 38 FPS range. The drop from Low to Ultra at 1080p is 72 FPS, representing a 44.4% reduction in average frame rate.

Moving to 2560x1440, the averages are 131 FPS on Low, 102 FPS on Medium, 76 FPS on High, and 73 FPS on Ultra. The Medium preset at this resolution shows a minimum of 86 FPS and a maximum of 117 FPS, with a 31 FPS range. The transition from Low to Ultra at 1440p reduces average FPS by 58 frames, a 44.3% decrease. At 3840x2160, the averages fall to 96 FPS on Low, 75 FPS on Medium, 56 FPS on High, and 54 FPS on Ultra. The Medium preset at 4K shows a minimum of 64 FPS and a maximum of 86 FPS, with a 22 FPS range. The drop from Low to Ultra at 4K is 42 FPS, a 43.8% reduction.

The pattern across all three resolutions shows that the Ultra preset costs roughly 44% of the Low preset's frame rate, regardless of resolution. This consistency suggests that the settings scaling is primarily GPU-bound, with the additional visual effects taxing the shading units and texture units uniformly across resolutions.

Resolution Scaling

The frame rate scaling from 1080p to 4K reveals where the bottleneck lies. At Low settings, the average FPS drops from 162 at 1080p to 131 at 1440p (a 19.1% reduction) and then to 96 at 4K (a 26.7% reduction from 1440p). The total drop from 1080p to 4K at Low is 66 FPS, or 40.7%. At Medium settings, the progression goes from 126 at 1080p to 102 at 1440p (19.0% lower) and then to 75 at 4K (26.5% lower from 1440p), for a total reduction of 40.5%. High settings show 95 at 1080p, 76 at 1440p (20.0% lower), and 56 at 4K (26.3% lower from 1440p), a total drop of 41.1%. Ultra settings follow the same pattern: 90 at 1080p, 73 at 1440p (18.9% lower), and 54 at 4K (26.0% lower from 1440p), for a total reduction of 40.0%.

The near-constant percentage drop across all settings indicates that resolution scaling is consistent and predictable for this configuration. The smaller percentage loss when going from 1440p to 4K compared to 1080p to 1440p suggests that pixel throughput is not the sole limiting factor — if it were, the 4K transition would be proportionally larger given the higher pixel count. This points to a combination of CPU simulation overhead and GPU shading throughput sharing the load, with the CPU's 24 cores providing enough headroom to keep simulation updates flowing even at 4K. At 4K Ultra, the 54 FPS average is above the 50 FPS threshold that many flight sim enthusiasts consider acceptable for immersive gameplay, though it leaves limited headroom for complex scenery or heavy weather scenarios.

Settings Recommendations

The measured data supports a tiered approach to settings depending on the target display resolution. At 1920x1080, the Ultra preset delivers 90 FPS average, which is smooth for a flight simulator, and the High preset at 95 FPS offers nearly identical performance with only a 5 FPS difference. Given that Ultra at 1080p maintains 90 FPS, there is little reason to drop below High unless frame rate consistency is a priority. The Medium preset at 1080p provides 126 FPS with a minimum of 107 FPS, making it the best choice for users with high-refresh displays who want to maximize smoothness over visual fidelity.

At 2560x1440, the High preset delivers 76 FPS average, which is playable but not ideal for fast-paced maneuvering. The Medium preset at 102 FPS with a minimum of 86 FPS provides a better balance, offering a 34.2% higher average frame rate than High while maintaining a minimum above 85 FPS. The Ultra preset at 73 FPS is only 3 FPS lower than High, so if visual quality is paramount, Ultra at 1440p is viable, but Medium represents the best measured experience for maintaining high frame rates.

At 3840x2160, the Medium preset delivers 75 FPS average with a minimum of 64 FPS, which is the only 4K preset that stays comfortably above 60 FPS in the minimum frame rate. High at 56 FPS and Ultra at 54 FPS are both close to the 50 FPS threshold, making them suitable only for users who prioritize visual quality over frame rate stability. The Low preset at 96 FPS at 4K is smooth but strips out many of the visual features that make flight simulation immersive. For 4K users, Medium is the recommended preset based on the measured data, as it maintains frame rates above 60 FPS while retaining a reasonable level of visual detail.
