Microsoft Flight Simulator

Microsoft Flight Simulator pairs the Intel Core Ultra 7 165H with the AMD Radeon RX 7900M, a mobile combination that places in the 1575th position out of 3714 tested combos, putting it just above the middle of the database. The benchmark results show that this setup delivers playable performance across all tested resolutions and presets, with clear scaling patterns that point to the GPU as the primary constraint in most scenarios, although the CPU’s 16 cores and 22 threads provide the necessary headroom for the simulation’s heavy single-thread and physics loads.

How This Combo Ranks

The combo rank of 1575 out of 3714 tested combinations places this system squarely in the upper-mid pack of the database. The CPU’s percentile ranking of 84 means it outperforms the majority of processors tested, while the GPU’s percentile rank of 94 places it among the top 6% of all GPUs. The average benchmark score for the CPU is 34083, and the GPU averages 97487. This suggests the pairing is balanced for the 1080p and 1440p ranges, though 4K performance is limited by the GPU’s raw fill rate rather than CPU capacity.

Looking at the CPU’s nearest rivals, the Core Ultra 7 165H is virtually tied with the Intel Core Ultra 5 338H (a 0.3% difference) and the AMD EPYC 4244P and Ryzen AI 7 350 (both 0.4% behind). The AMD Ryzen 7 3700X sits 0.5% behind, so the 165H has a slight edge in synthetic benchmarks but real-world flight sim performance remains dependent on the combination’s ability to feed the GPU with high single-thread scores. The CPU’s single-core Cinebench R23 score of 1759 and multi-core score of 14551 are substantial for a laptop chip, reinforcing that the CPU is not the bottleneck in this test.

GPU Role

The AMD Radeon RX 7900M is a 16 GB GDDR6 part with a 256-bit memory bus, delivering 576.0 GB/s of bandwidth. Its base clock is 1825 MHz and boost reaches 2090 MHz, with memory running at 2250 MHz or 18 Gbps effective. The 4608 shading units, 288 texture mapping units, and 192 ROPs give it a pixel rate of 401.3 GPixel/s and a texture rate of 601.9 GTexel/s. These specs translate into 38.52 TFLOPS of FP32 performance. The GPU’s percentile rank of 94 puts it ahead of the AMD Radeon Pro VII by 0.4%, while the NVIDIA Quadro RTX 6000 leads by 4.3%, the AMD Instinct MI60 trails by 5.4%, and the RTX A4500 lags by 6.3%.

In the game’s context, the GPU’s high bandwidth and ROP count directly influence the 4K performance, where the combos’s average FPS drops from 135 at 1080p Low to 80 at 4K Low, a reduction of 55 FPS. The GPU’s RDNA 3.0 architecture and 16 GB of VRAM are sufficient for the simulation’s texture-heavy environments, but the card’s power envelope of 180 W may limit sustained clocks in mobile chassis, a factor not directly measured here.

Resolution Scaling

The measured FPS shows a clear pattern of performance degradation as resolution increases. At 1080p Low, the system averages 135 FPS; at 1440p Low, it drops to 109; and at 4K Low, it falls further to 80. This represents a 41% reduction from 1080p to 4K at Low settings. The scaling is less linear at higher presets: Ultra at 1080p yields 75 FPS, 1440p Ultra gives 61, and 4K Ultra sits at 45. The drop of 30 FPS from 1080p to 4K at Ultra suggests that the GPU’s fill rate—192 ROPs and 401.3 GPixel/s—is the limiting factor, as the CPU’s 16-core/22-thread configuration can keep up with the single-threaded demands of the flight engine.

The data indicates that 4K performance is likely bound by the GPU’s memory bandwidth and pixel throughput. The 256-bit memory bus and 576 GB/s bandwidth are substantial, but the 4K resolution requires more than just bandwidth—the pixel fill rate and texture rate become critical. The reduction from 1080p Medium (105 FPS) to 1440p Medium (85 FPS) is 20 FPS, then to 4K Medium (63 FPS) is another 22 FPS drop. This pattern suggests that the GPU is the limiting component at 4K, while at 1080p, the CPU’s single-thread performance may impose a ceiling, as the rate from 1080p Low (135 FPS) to 1440p Low (109) is not as steep as the GPU scaling.

Measured FPS Breakdown

The data provides a full matrix of average FPS across 12 combinations of resolution and settings. At 4K, the High preset (not further defined in the pack) yields 47 FPS, Medium yields 63 with a minimum of 53 and maximum of 72, Low yields 80, and Ultra yields 45. The jump from Low to Medium is 17 FPS, but from Medium to High only drops to 47, a difference of 16 FPS, and then to Ultra is 45, a negligible 2 FPS reduction. This indicates that High and Ultra settings at 4K are nearly identical in performance, suggesting a GPU-bound limit.

At 1440p, High produces 64 FPS, Medium 85 (72-97), Low 109, and Ultra 61. The 1080p results show High at 79, Medium 105 (89-121), Low 135, and Ultra 75. The 1080p Ultra to 1440p Ultra drop is 14 FPS, while 4K Ultra is 45, a further 16 FPS decrease. The minimum and maximum FPS are only provided for Medium settings across all resolutions. At 1080p Medium, the range is 89 to 121; at 1440p, 72 to 97; and at 4K, 53 to 72. This shows that variance grows with resolution, indicating that the flight simulator’s complex scenes cause more frame-time spikes at higher resolutions.

Settings Recommendations

For a 60 FPS target, the data suggests that 1080p can run at Ultra with 75 FPS, leaving headroom. At 1440p, Medium at 85 FPS offers a smooth experience with a 72 FPS minimum, while High at 64 FPS is just above the 60 FPS threshold. At 4K, the best choice is Medium at 63 FPS with a minimum of 53, which may be acceptable for less demanding users, but High at 47 and Ultra at 45 are below 60 FPS. The data indicates that Medium is the optimal preset for 4K to maintain the highest average while keeping minimums above 50.

For users prioritizing smoothness over visuals, 1080 Low at 135 FPS or 1440 Low at 109 FPS provide the highest frame rates, but the Medium preset delivers a better visual experience with a modest FPS hit (30 FPS less at 1080p). The measured 1080p Medium range of 89-121 FPS shows that even with dips, the frame rate stays well above 60. In contrast, 4K Medium’s minimum of 53 FPS may cause stutter in dense scenes, so a reduction to 1440p High at 64 FPS would be safer for a locked 60 FPS experience. The lack of min/max data for other presets means the Medium rows are the only ones that provide frame-time stability data, making them the most reliable choice for a consistent experience.

CPU Role

The Intel Core Ultra 7 165H is a 16-core, 22-thread processor based on Meteor Lake, with a base clock of 3.80 GHz and a boost of 5.00 GHz. It has 24 MB of shared L3 cache and a dual-channel DDR5 memory interface with 89.6 GB/s bandwidth. The CPU’s Cinebench R23 multi-core score is 14551, placing it at the 84th percentile, and its single-core score of 1759 is strong for flight sim, which relies heavily on single-threaded IPC. The PassMark single-thread score of 3509 confirms this, while the multi-thread score of 25933 shows the parallel capability.

In Microsoft Flight Simulator, the CPU’s role is to simulate the physics and scenery, which often limits performance at lower resolutions. The 1080p Low to Medium scaling (135 to 105 FPS) is likely CPU-bound, as the GPU has more headroom at lower resolutions. The CPU’s memory bandwidth of 89.6 GB/s is adequate, and the 24 MB L3 cache helps with the game’s asset streaming. The 22 threads can handle the simulation’s background processes, but the single-thread performance is the key factor for maintaining high FPS. When compared to rivals, the 165H is 0.3% faster than the Ultra 5 338H, but 0.4% slower than the EPYC 4244P and Ryzen AI 7 350, indicating that the CPU is not a performance outlier in either direction.

The TDP of 28 W for the CPU and 180 W for the GPU suggests that this is a mobile platform, where thermal and power limits can affect sustained performance. However, the measured FPS indicates that the boost clocks of 5.00 GHz and 2090 MHz are being maintained during the test, as the performance is consistent with the CPU’s benchmark scores. The CPU’s PCIe Gen 5 support with 8 lanes provides sufficient bandwidth for the GPU, though the actual bus is PCIe 4.0 x16 for the graphics card, which is the standard for this class.
